Published: May 2023

Aedes aegypti is a holometabolous insect, vector of medical importance for arboviral transmission, and has shown the ability to develop chemical larvicides resistance, which are the worldwide used to control mosquitoes’ population because of their low cost. Due to the well-known photophobia, a striking characteristic of the behavior of A. aegypti larvae, this study aimed to observe the development of this insect in its larval stage under the action of certain ranges of light radiation and its possible biological effects. For that, the experiments used larvae in L1, observed during seven days under the action of LEDs (light-emitting diode) that emitted light at different wavelengths, with six different colors, one for each experiment. Some were tested with a light-dark interval every 10 minutes and others every two minutes, with three repetitions. At the end, mosquitoes, pupae and larvae were counted and the data submitted to statistical evaluation. The experiment showed a significant difference between the control and the different wavelengths used, when exposed at two-minute intervals. LEDs that emitted blue (λ = 457.9 nm) and white (λ = 448.58 nm) wave frequencies were the most promising for the development of equipment that could act synergistically with other forms of control in order to improve its efficiency.
The role of habitat complexity in the survival rates of migratory (native) and sedentary (non-native) species of fish larvae
Authors: Lacerda Carlos Henrique Figueiredo , Soares Claudemir Martins , Hayashi Carmino
Published: May 2023

The increasing losses of original features of many riverine environments and the consequent decline of native aquatic species are now a widely recognized problem. The main river basins of South America have been undergoing constant changes in their communities of fish, with native migratory species disappearing and the rising of sedentary exotic ones. However, few studies report experiments that qualify and/or quantify this correlation. Three experiments were conducted to evaluate the predation mortality of two species of fish larvae (native and non-native) regarding their habitat features. The hypothesis that natural features of habitat (aquatic vegetation and water turbidity) controls the survival rates of fish larvae was tested. The experiments highlight the importance of community structure on population dynamics. The native fish larvae showed to be more adapted than the non-native to using the aquatic plants for refuge. The habitat complexity can be closely related to the persistence of native migratory fish species.

Published: May 2023

Latin American countries have common characteristics: increase in automobile use, and decrease in the interest of users for public transport by bus caused by unsustainable urban mobility. Of these, users’ interest in public transport by bus has the most significant potential for sustainable transport changes. Therefore, this paper aimed to understand how the interaction between the importance and satisfaction of users to transport attributes can help promote the increase in the passengers’ transport demand in medium-sized cities of developing countries. The interaction between the users’ stated importance and the users’ satisfaction for automobile and public transport by bus was analyzed regarding attributes of safety, comfort, transport costs, and travel time. The study was performed in the city of Barreiras, state of Bahia, Brazil. Likert scale data analysis used three approaches that set unique importance and satisfaction ratings employed on the graphic tool Importance-Performance Analysis. It was concluded that interaction between the data of importance and satisfaction is effective, reliable, and allows the comparative analysis between the transport attributes, enabling the prioritization of strategies that help the promotion of passenger transport.

Published: May 2023

The objective was to identify the effect of regulated deficit irrigation on physiological, yield and root descriptors of ‘Tommy Atkins’ mango tree grown in a semi-arid region of Brazil. The work was carried out during two production cycles on an 11-year-old mango orchard. The design was randomized blocks with five treatments and six replications. Irrigation treatments were based on the trees’ development stage: T1, irrigation supplying 100% of the crop evapotranspiration (ETc) in three production stages: fruit set stage (SI), fruit expansion stage (SII), and physiological maturation stage of the fruits (SIII); T2, 50% ETc in SI and 100% ETc in SII and SIII; T3, 100% ETc in SI and SIII and 50% ETc in SII; T4, 100% ETc in SI and SII, and 50% ETc in SIII; and T5, without irrigation in all three stages. Physiological data were measured once per stage. After harvesting the second cycle, roots were collected, following a completely randomized design, with five treatments and three replications, to determine the total root length density. Total or partial water deficit in ‘Tommy Atkins’ mango trees was identified by decreasing transpiration (E) and photosynthesis (A) and increasing leaf temperature (Tleaf). The total root length density is similar in all irrigation strategies up to 1 m horizontal distance and 0.10 m depth. Water deficit applied in the physiological maturation stage improves yield and water use efficiency.

Does mobility restriction significantly control infectious disease transmission? Accounting for non-stationarity in the impact of COVID-19 based on Bayesian spatially varying coefficient models
Authors: Jaya I Gede Nyoman Mindra , Chadidjah Anna , Kristiani Farah , Darmawan Gumgum , Christine Princidy Jane
Published: May 2023

COVID-19 is the most severe health crisis of the 21st century. COVID-19 presents a threat to almost all countries worldwide. The restriction of human mobility is one of the strategies used to control the transmission of COVID-19. However, it has yet to be determined how effective this restriction is in controlling the rise in COVID-19 cases, particularly in small areas. Using Facebook's mobility data, our study explores the impact of restricting human mobility on COVID-19 cases in several small districts in Jakarta, Indonesia. Our main contribution is showing how the restriction of human mobility data can give important information about how COVID-19 spreads in different small areas. We proposed modifying a global regression model into a local regression model by accounting for the spatial and temporal interdependence of COVID-19 transmission across space and time. We applied Bayesian hierarchical Poisson spatiotemporal models with spatially varying regression coefficients to account for non-stationarity in human mobility. We estimated the regression parameters using an Integrated Nested Laplace Approximation. We found that the local regression model with spatially varying regression coefficients outperforms the global regression model based on DIC, WAIC, MPL, and R2 criteria for model selection. In Jakarta's 44 districts, the impact of human mobility varies significantly. The impacts of human mobility on the log relative risk of COVID-19 range from –4.445 to 2.353. The prevention strategy involving the restriction of human mobility may be beneficial in some districts but ineffective in others. Therefore, a cost-effective strategy had to be adopted.

Published: May 2023

Clubfoot is a congenital anomaly affecting 1/1,000 live births. Ponseti casting is an effective and affordable treatment. About 75% of affected children have access to Ponseti treatment in Bangladesh, but 20% are at risk of drop-out. We aimed to identify the areas in Bangladesh where patients are at high or low risk for drop-out. This study used a cross-sectional design based on publicly available data. The nationwide clubfoot program: ‘Walk for Life’ identified five risk factors for drop-out from the Ponseti treatment, specific to the Bangladeshi setting: household poverty, household size, population working in agriculture, educational attainment and travel time to the clinic. We explored the spatial distribution and clustering of these five risk factors. The spatial distribution of children <5 years with clubfoot and the population density differ widely across the different sub-districts of Bangladesh. Analysis of risk factor distribution and cluster analysis showed areas at high risk for dropout in the Northeast and the Southwest, with poverty, educational attainment and working in agriculture as the most prevalent driving risk factor. Across the entire country, twenty-one multivariate high-risk clusters were identified. As the risk factors for drop-out from clubfoot care are not equally distributed across Bangladesh, there is a need in regional prioritization and diversification of treatment and enrolment policies. Local stakeholders and policy makers can identify high-risk areas and allocate resources effectively.

Published: May 2023

Introduction. A national action plan for the acceleration of stunting reduction was prepared to encourage and strengthen convergence between programs through a stunting-risk family approach. The increasing role of Family Planning Instructors in assisting families at risk of stunting becomes a challenge to support behavioral change in the community.Materials and Methods: This study aims to determine the relationship between years of service, competence, attitude, transformational leadership, and performance of Family Planning Instructors in assisting families at risk of stunting in Lampung. The research was carried out in April-May 2022. This is a cross-sectional- quantitative study.Results and Discussion: The results showed that 49.3% of the Family Planning Instructors had years of service more than 28 years, only 36.4% were well competent, 43.1% had a positive attitude, 68% felt positive transformational leadership and 64.9% had an active performance. Years of service (r=0.017), competence (r=0.004), attitude (r=0.025) and transformational leadership (r=0.000) were proven (CI=95%) to be significantly related to the performance of Family Planning Instructors. However, only competence, attitude and transformational leadership were simultaneously related to performance. Transformational leadership had the strongest relationship with performance, that Family Planning Instructors who perceived positive transformational leadership had 5,8 times higher active performance than those who perceived negative transformational leadership after being controlled by competence and attitude variables. Conclusions: It is necessary to increase the competence, operational support in the field and leadership awareness as good role models who inspire, motivate, stimulate creativity and innovation, and pay more attention to the potential of Family Planning Instructors.

Published: May 2023

Background: During the COVID-19 pandemic, the psyche nursing staff might suffer from burnout syndrome. This subsequently leads to decreased working performance which might compromise the quality of care. Nurses experience depersonalization.Objective: The study aimed to determine the effect of burnout syndrome on job satisfaction among nurses and how self-efficacy can solve the problem.Materials and Methods: Mix method study was conducted among 79 nurses from October 2021 until February 2022. The quantitative data were collected using the Maslach Burnout Inventory questionnaire and Minnesota Satisfaction Questionnaire via proportional random sampling. The qualitative data were collected by thematic analysis to find out nurses’ self-efficacy during the pandemic.Results: The results of the Spearman rank test prove a significant value (p)=0.004 with coefficient correlation (r)=-0,315. It means that burnout syndrome can affect job satisfaction negatively. Nurses should be skillful at conducting nursing care according to their assigned duties (performance outcome). Improving communication ability, especially the ability to utilize the local language. Mastering international languages might also help to cope with the market’s demand in the future (verbal persuasion). Nurses should be careful in perceiving the faced situation (observational learning) and try to think positively (emotional arousal).Conclusion: The higher the level of job satisfaction, the lower the level of burnout syndrome. Therefore, nurses should improve their selfefficacy as they are the healthcare front liners during the pandemic. With better self-efficacy, the quality of care should improve as well.
The increasing rate of marriages and premarital pregnancies in adolescents during the transitional period of changes to the marriage law

Published: May 2023

The increasing number of adolescent marriages can have various impacts on society. The government’s effort to reduce the number of adolescent marriages is to revise Marriage Law no. 16 of 2019, which changes the minimum age for marriage to 19 years old. This study focuses on analyzing the differences in trends of adolescent marriage and premarital pregnancy during the transitional period of changes to the marriage law. This research was a cross-sectional study using secondary data from the Central Statistics Agency, Ministry of Religion, and Religious Courts of Malang Regency. The data related to adolescent marriage were the data obtained in 2016-2020. The adolescent marriage rate map was made using the QGIS application. The marriage rate of adolescents aged 19 years old increased. In 2016 the prevalence was 1.38% of the total number of marriages, and it increased to 5.85% in 2020. The marriage dispensation rate also increased from 1.77% (2016) to 8.74% (2020). The major reason for applying for marriage dispensation is because the adolescents are still aged 19 years old and have premarital pregnancies. The highest marriage rate of males was in 5 sub-districts, while the highest marriage rate for women was in 31 sub-districts. Changes in the minimum age limit for marriage do not automatically reduce the rate of adolescent marriage. Thus, it is important to have a synergistic role in society to increase awareness for a healthy marriage, relationship, and morale.

Published: May 2023

Background: Indonesia is one of the countries that have a high smoker prevalence globally. Therefore, a smoking cessation program is key to reducing the smoking prevalence in Indonesia. The role of health workers is necessary for smoking cessation programs. However, smoking behavior among health workers could limit smoking cessation practices for patients.Objective: This study aims to analyze smoking behavior and 5A smoking cessation (Ask, Advice, Assess, Assist, and Arrange) practices among health workers.Materials and Methods: This study design is cross-sectional with a simple random sampling from the population of health workers in Surabaya. The total sample of this study counted 60 health workers. The data were analyzed in univariate and bivariate using SPSS 18 application. Bivariate analysis using a chi-square or Fisher exact test was conducted to analyze the relationship between smoking status and 5A smoking cessation practice.Results: Report of main outcomes or findings, including (where relevant) levels of statistical significance and confidence intervals. The result of this study shows that the asking practice was the most practiced item in the 5A model among health workers (98.3%). There was no significant association between smoking behavior and 5A implementation among health workers (PR=0.40; 95%CI: 0.52-5.30; P=1.67).Conclusions: There was no significant association between respondents’ characteristics, smoking cessation training, and professional roles with 5A implementation.

Published: May 2023

Background: The Non-Smoking Area is a room or area that is declared prohibited for smoking activities or activities to produce, sell, advertise and/or promote tobacco products. The Regional Regulation on Non-Smoking Areas in Indonesia has been enacted since 2013, including in public places such as restaurants and cafes, but has not yet been fully implemented. The Non-Smoking Area Policy is the best choice to implement in government and private institutions. Objective: This study aimed to determine participation in implementing Non-Smoking Areas in restaurants and cafes in Indonesia. Materials and Methods: This study is a cross-sectional quantitative survey with an analytical survey approach, with a purposive sampling technique of 419 restaurants and cafes, analyzed with the help of the chi-square test and logistic regression. Results: The results showed that age, income, smoking status, knowledge, and attitudes were related to participation in implementing Non-Smoking Areas (P value 0.05). The attitude variable in multivariate logistic regression analysis had the most significant impact (OR: 2,949; 95% CI: 1,716 -5,069), and the smallest effect is the age factor (OR: 0,591; 95% CI: 0,361-0,967). Conclusions: Age, smoking status, income, knowledge, and attitudes regarding Non-Smoking Areas are the factors that contribute to the majority of restaurant and cafe managers in Indonesia not participating in the implementation of Non-Smoking Areas. Therefore, the government should maximize the role of the Non-Smoking Areas task force, socialize and provide awards such as the title of “Breathing Free” restaurant and cafe.
Predicting dengue incidence using panel data analysis
Authors: Firdaust Mela , Yudhastuti Ririh , Mahmudah Mahmudah , Notobroto Hari B.
Published: May 2023

Dengue is the most rapidly spreading infectious disease, especially in Indonesia. Dengue virus is transmitted by the bite of female Aedes mosquitoes. The high human population density and proximity to vector breeding places strengthen the interaction between the virus, vector, and humans as hosts. Using dengue incidence panel data during 2018-2019 in 34 provinces in Indonesia, this study examined the effect of human population density as a demographic variable and vector control on dengue incidence in Indonesia. The time series data were analyzed using EViews. The fixed effect model estimation showed that dengue incidence was significantly associated with demographic variables measured as human population density, with a P-value of 0.02. The vector control variable shows an insignificant association with dengue incidence. But simultaneous analysis between human population density and vector control on dengue incidence has a significant association with probability F (statistic) = 0.000. Our study demonstrated that densely populated provinces in Indonesia have a very high incidence of dengue. Improving sanitation in densely populated settlements can prevent and control dengue incidence.

Methods: The research design was cross-sectional, the number of samples was 131 out of 378 primipara mothers and lactating pregnant women selected by cluster random sampling. Chi-square and logistic regression analysis α=0.05. data was collected in April 2021.Results: The results showed that exclusive breastfeeding was associated with the onset of lactation and early initiation of breastfeeding (p-value = 0.022 and p-value = 0.014). EIBF and timely onset lactation had a greater chance of successful EB. Conclusion: EB and the timely onset of lactation are likely to determine the success of EB. Therefore, EIBF and lactation onset are enhanced for EB success.
Does size matter? Bat diversity and the use of rock shelters in Brazil
Authors: Trajano Eleonora , Etges Matheus Fragoso
Published: May 2023

A positive correlation between cave size and bat diversity has been recorded by some authors for different cave areas in South America. We analyzed published and otherwise available data from three Brazilian karst areas and phytogeography domains, including NE and SE Atlantic Forest and Cerrado (savannah-like vegetation), encompassing a wide range of cave sizes. We found no such correlation, as expected in view of previous observations by researchers and speleologists. We discuss the ecological implications of different ways to measure bat diversity, i.e. the accumulative number of species (sequential use of caves) vs. the number of species at a given occasion (species in actual cohabitation) vs. bat abundance (numbers of individuals), as well as speleological topics related to the concept of caves (based on an anthropomorphic definition, not applicable to other species), the problems of estimating topographic variables such as cave area and volume, and the value of including cave temperatures in the analyses. Multiple interacting variables may influence the composition of cave bat communities and bat species richness and abundance. The most important ones would be the density of caves in a given area (related to lithology – calcareous vs. siliciclastic caves), regional climates, and degree of preservation of epigean habitat. Cave morphology, number and size of entrances, and presence of water bodies, as well as interactions with other species, must also be considered. In conclusion, as a general statement for tropical and subtropical bats, cave size (in the human sense) by itself does not matter, except perhaps for one-off situations. Finally, a brief overview of the diversity of cave bats in Brazil is presented.
Chemical compositions of flowback and produced water from the Duvernay shale and Montney tight reservoir developments in Western Canada: potential for lithium resources from wastewater
Authors: Kingston A W , Jiang C , Wang X , Hobbs T
Published: May 2023

Increasing global demand for lithium coupled with a need to characterize domestic resources necessitates an expanded assessment for lithium production from unconventional sources. Oilfield brines are known to host elevated lithium concentrations and represent a
prime candidate for lithium extraction. The purpose of this report is to expand our knowledge of brine chemistry within the Western Canadian Sedimentary Basin with a focus on the Montney and Duvernay formations. Specifically wells that are undergoing hydrocarbon production stimulated via hydraulic
fracturing (HF) are sampled with the eventual goal of assessing the suitability of extracting lithium from flowback and produced wastewater. Two water chemistry datasets are presented, the first consisting of samples derived from numerous wells within the Montney and Duvernay formations, and the
second dataset includes time series samples from several wells in the Montney and Duvernay formations illustrating temporal variations in water chemistry following the onset of well re-open and fluid production after HF operations. The maximum measured lithium concentration in the Montney Fm. is
76.8 mg/L with an average of 52.9 mg/L. Maximum measured lithium concentration in the Duvernay Fm. is 78.6 mg/L with an average of 44.9 mg/L. Comparison of Montney and Duvernay sodium-chloride-bromide system with seawater evaporation trends suggests halite dissolution likely played a role in the
evolution of brine chemistry. Lithium concentration in brines is positively correlated with potassium concentration and inversely correlated with pH. Water chemistry time series reveal increasing lithium concentrations over time associated with increasing proportions of formation-derived water in
produced fluids. Understanding spatial and temporal variations in lithium concentrations is essential for evaluating the resource potential of oilfield brines as well as informing appropriate extraction technologies.
Adverse effects of early-life stress: focus on the rodent neuroendocrine system
Authors: Lee Seung Hyun , Jung Eui-Man
Published: May 2023

Early-life stress is associated with a high prevalence of mental illnesses such as post-traumatic stress disorders, attention-deficit/hyperactivity disorder, schizophrenia, and anxiety or depressive behavior, which constitute major public health problems. In the early stages of brain development after birth, events such as synaptogenesis, neuron maturation, and glial differentiation occur in a highly orchestrated manner, and external stress can cause adverse long-term effects throughout life. Our body utilizes multifaceted mechanisms, including neuroendocrine and neurotransmitter signaling pathways, to appropriately process external stress. Newborn individuals first exposed to early-life stress deploy neurogenesis as a stress-defense mechanism; however, in adulthood, early-life stress induces apoptosis of mature neurons, activation of immune responses, and reduction of neurotrophic factors, leading to anxiety, depression, and cognitive and memory dysfunction. This process involves the hypothalamus-pituitary-adrenal axis and neurotransmitters secreted by the central nervous system, including norepinephrine, dopamine, and serotonin. The rodent early-life stress model is generally used to experimentally assess the effects of stress during neurodevelopment. This paper reviews the use of the early-life stress model and stress response mechanisms of the body and discusses the experimental results regarding how early-life stress mediates stress-related pathways at a high vulnerability of psychiatric disorder in adulthood.

Published: May 2023

Dans les écosystèmes aquatiques, la prédation des microalgues contribue à contrôler leur prolifération, susceptible de dégrader la qualité de l’eau. Cette étude détermine le rôle de Heterotis niloticus dans le biocontrôle de la qualité de l’eau. Les microalgues ont été collectées de novembre 2020 à janvier 2021 dans le lac de barrage de Samendeni au Burkina Faso. La longueur standard (Ls) de 100 individus de Heterotis niloticus a été mesurée et les bols alimentaires de 35 d’entre eux ont été échantillonnés. Dans le plan d’eau, 14 genres de phytoplanctons et 24 genres de périphytons ont été identifiés, avec des concentrations respectives de 616,67 à 38233,33 cellules/ml et 0,19 à 38,48 cellules/cm2 . L’analyse des bols alimentaires a permis d’identifier 25 genres de microalgues avec des concentrations de 24350,65 à 1485389,61 cellules/ml. Parmi ces microalgues, 20 genres ont été recensés dans le plan d’eau. Elles constituent selon l’Organisation Mondiale de la Santé, des bioagresseurs de la qualité de l’eau. La comparaison des biomasses algales consommées par les individus des classes 260≤Ls1≤575 mm et 575≤Ls2≤950 mm, n’a pas montré de différence significative (p=0,12). Heterotis niloticus a un large spectre d’action sur les microalgues et contribue à contrôler leur prolifération dans les retenues d’eau à multiples usages.

English title: Study of the grazing and filtering of the algal microflora by Heterotis niloticus (Cuvier, 1829) and biocontrol of the water quality of the hydro-agricultural dam lake of Samendeni in Burkina Faso

In aquatic ecosystems, predation of microalgae helps to control their proliferation that could jeopardize the water quality. This study aimed at determining the role of Heterotis niloticus in the biocontrol of water quality. The microalgae were collected from November 2020 to January 2021 in the Samendeni dam lake. The standard length (Ls) of 100 individuals of H. niloticus was measured and the food bowl of 35 of them were sampled. In the water body, 14 genera of phytoplankton and 24 genera of periphyton were identified, with respective concentrations of 616.67 to 38,233.33 cells/ml and 0.19 to 38.48 cells/cm2 . The food bowl of Heterotis niloticus made it possible to identify 25 genera of microalgae with concentrations between 24,350.65 and 1,485,389.61 cells/ml. Among these microalgae, 20 genera have been identified in the watershed. These microalgae are, according to the World Health Organization, bioaggressors of water quality. The comparison of the diet according to the classes 260≤Ls1≤575 mm and 575≤Ls2≤950 mm, showed that there is no significant difference (p-value=0.12) between algal biomasses consumed by the individuals. Heterotis niloticus has a broad spectrum of action on microalgae and therefore can contribute to limit their proliferation in multipurpose water reservoirs.

Les zones humides sont essentielles à la promotion du développement durable. Elles maintiennent les fonctions des écosystèmes et assurent la croissance économique. Cependant, il est constaté une dégradation continue de ces écosystèmes et des services écosystémiques qu’elles fournissent. L’objectif de la présente étude est d’analyser la dynamique spatio-temporelle des surfaces en eau de la zone humide du bassin du NakanbéMané, au Burkina Faso, de 2000 à 2020 et de déterminer les facteurs climatiques explicatifs. La dynamique des surfaces en eau a été analysée à l’aide d’un algorithme de détection des eaux, basé sur les indices spectraux via la plateforme Google Earth Engine. Quant aux facteurs climatiques, ils ont été analysés à l’aide des indices climatiques. Les résultats montrent une tendance significative généralisée à la baisse des surfaces en eau. Les causes climatiques probables en sont (i) la longue période de sécheresse de 1991 à 2005, caractérisée par un déficit pluviométrie de 3,7%, (ii) la hausse de l’évapotranspiration de 8,5%, consécutive à la hausse des températures de 0,03°C/an, (iii) l’augmentation significative de l’intensité des pluies de 0,085 mm/an. Ces résultats constitueront un support scientifique pour orienter les décideurs vers une gestion durable de la zone humide du Nakanbé-Mané. Cela passe nécessairement par l’élaboration d’un plan de gestion intégré de ladite zone humide

English title: Spatio-temporal dynamics of water surfaces in the Nakanbé-Mané wetland in Burkina Faso

Wetlands are essential for promoting sustainable development. They maintain ecosystem functions and ensure economic growth. However, there is a continuous degradation of these ecosystems and the ecosystem services they provide. The objective of the present study is to analyze the spatio- temporal dynamics of the water surfaces of the wetland of the Nakanbé- Mané basin, in Burkina Faso, from 2000 to 2020 and to determine the explanatory climatic factors. The dynamics of water surfaces were analyzed using a water detection algorithm based on spectral indices via the Google Earth Engine platform. As for the climatic factors, they were analyzed using the climatic indices. The results show a significant generalized trend of decreasing water surfaces. The probable climatic causes are (i) the long period of drought from 1991 to 2005, characterized by a rainfall deficit of 3.7%, (ii) the increase in evapotranspiration of 8.5%, following the rise in temperature of 0.03°C/year, (iii) the significant increase in rainfall intensity of 0.085 mm/year. These results will constitute a scientific support to orient the decision-makers towards a sustainable management of the wetland of Nakanbé- Mané. This will necessarily involve the development of an integrated management plan for the said wetland.

Les forêts classées sont des aires de conservation de la biodiversité en Afrique de l’Ouest. La présente étude a été initiée afin d’évaluer la diversité de la flore de la forêt classée de Kuinima à l’ouest du Burkina Faso. Les données ont été collectées par inventaires floristiques. Les caractéristiques des ligneux ont été obtenues à travers un échantillonnage stratifié dans des placettes de formes adaptées aux formations végétales. La méthode des points quadrats a permis de mesurer les paramètres des herbacées. Au total, 254 espèces dont 158 herbacées, 92 ligneux et 4 sub ligneux ont été dénombrées. Ces espèces appartiennent à 61 familles et 175 genres. L’analyse de la structure a montré une densité moyenne de 116 pieds de ligneux à l’hectare avec une surface terrière globale de 2,05 m2 /ha. L’ensemble des paramètres étudiés révèle que la végétation de la forêt de Kuinima est de type savanicole, constituée d’un peuplement à dominance arbustive. C’est une forêt qui subit des perturbations d’origine anthropique, mais demeure un refuge de la biodiversité végétale. Ainsi, des mesures rigoureuses de conservation doivent être entreprises pour sa réhabilitation et sa survie.

English title: Diversity and floristic structure of plant formations in the Kuinima classified forest in the Sudanian zone of Burkina Faso

Classified forests are biodiversity conservation areas in West Africa. The present study was initiated to assess the diversity of the flora of the Kuinima classified forest in western Burkina Faso. Data were collected by floristic inventories. The characteristics of the woody plants were obtained through stratified sampling in plots with shapes adapted to the plant formations. The quadrat point method was used to measure herbaceous parameters. In total, 254 species were counted, including 158 herbaceous, 92 woody and 4 subwoody species. These species belong to 61 families and 175 genera. The analysis of the structure showed an average density of 116 woody plants per hectare with an overall basal area of 2.05 m2/ha. All the parameters studied reveal that the vegetation of the Kuinima forest is of the savannah type, consisting of a stand dominated by shrubs. It is a forest that is subject to anthropogenic disturbances, but remains a refuge for plant biodiversity. Thus, rigorous conservation measures must be undertaken for its rehabilitation and survival.

Cuscuta australis R. Br (cuscute) est une plante parasite de plus en plus présente au Burkina Faso qui infeste les tiges et les feuilles d’une large gamme de plantes. Cette étude visait à appréhender la diversité des plantes hôtes de C. australis au Burkina Faso. Suite à une prospection dans la ville qui a permis de repérer lesfoyers de C. australis, les plantes infestées par la cuscute ont été inventoriées et identifiées. Les résultats ont montré une grande diversité des plantes hôtes composées de 62 espèces appartenant à 58 genres et 27 familles. Une proportion de 85,38% de ces plantes relève de la classe des dicotylédones contre 14,62% de monocotylédones. Un taux de 34,5% des hôtes inventoriées sont des plantes cultivées, les 65,5% étant des plantes sauvages. Les herbacées sont les plus nombreuses avec 86,55% tandis que les ligneux sont représentés à 13,45%. Ces résultats permettraient d'alerter les producteurs et les décideurs sur la nécessité d'adopter des stratégies de lutte adaptées pour limiter la propagation de C. australis dans les champs.

Les performances zootechniques des souches de Oreochromis niloticus sont des facteurs déterminants dans la réussite de leur élevage. Cette étude visait à caractériser les performances des souches Bouaké (introduite) et Sirba (locale) au Burkina Faso. La production de larves et la survie des géniteurs ont été évaluées pendant 5 mois dans 3 happas contenant chacun 9 femelles (129,28 g ± 18,32). Les performances de croissance et de survie des juvéniles monosexes mâles (24,81 g ± 3,27) ont été déterminées pendant 6 mois dans 3 happas de 50 juvéniles chacun. Les taux de survie étaient de 100% chez les géniteurs des deux souches et chez les juvéniles Bouaké, contre 96,00% ± 2,00 chez les juvéniles Sirba. Les moyennes de production bihebdomadaire de larves par happa étaient de 933 ± 1130 chez la souche Bouaké et 1129 ± 1223 chez celle de la Sirba. Les gains de poids quotidiens des juvéniles étaient de 2,05 g/j ± 0,02 chez la souche Bouaké et 1,11 g/j ± 0,07 chez celle de la Sirba. Ces résultats montrent que les performances de reproduction des deux souches ne diffèrent pas significativement. Cependant, le potentiel de croissance de la souche Sirba pourra être davantage amélioré après sélection génétique.

English title: Characterization of the zootechnical performance of wild (Sirba) and domesticated (Bouaké) strains of Oreochromis niloticus (Linné, 1758) in Burkina Faso

The zootechnical performance of Oreochromis niloticus strains is a determining factor in their successful rearing. This study aimed at characterizing the performance of the Bouaké (introduced) and Sirba (local) strains in Burkina Faso. Larval production and broodstock survival were evaluated for 5 months in 3 happas each containing 9 females (129.28 g ± 18.32). The growth and survival performances of all-male juveniles (24.81 g ± 3.27) was determined during 6 months in 3 happas of 50 juveniles each. Survival rates were 100% for broodstock of both strains as well as for Bouaké juveniles and 96.00% ± 2.00 for Sirba juveniles. The average biweekly larval production per happa was 933 ± 1130 in the Bouaké strain and 1129 ± 1223 in the Sirba strain. Daily weight gains of all-male juveniles were 2.05 g/d ± 0.02 in the Bouaké strain and 1.11 g/d ± 0.07 in the Sirba strain. These results show that the reproductive performance of the two strains does not differ significantly. However, the growth potential of the Sirba strain could be further improved after genetic selection.
