The present investigation was designed to uncover the effect of melatonin on serum calcium, phosphorus and glucose concentration following restoration of ovarian cyclicity in summer anestrus buffalo. The investigation was conducted on 28 healthy postpartum Murrah buffalo cows of age 5.11Â±0.62 years having body weight of 539Â±17.48 kg maintained under isomanagerial conditions with intensive system. Buffaloes diagnosed as summer anestrus (28) on the basis of absence of estrus signs three months postpartum, absence of ovarian activity by rectal examination and serum progesterone assay at 10 days interval. Buffaloes were grouped as untreated (Group I, sterilized corn oil, 8) and treated (Group II, single S/C injection of melatonin (MLT) @18 mg/50 kg b.wt in sterilized corn oil, 20). Estrus detection was carried out twice daily using teaser bull parading along with observation of behavioural estrus signs till day 28 post-treatment. Blood samples were collected at 4-day interval starting from day 8 pretreatment to 28 day post-treatment and for the entire cycle length in responded animals at 4-day interval. Serum calcium, phosphorus and glucose were estimated by commercial kits. Serum Ca, P and glucose concentrations in MLT treated and control buffaloes did not differ significantly within and between both groups. Serum Ca, P and glucose concentrations did not alter significantly between days of MLT induced estrous cycle. However, the group and period effect as well as interaction effect of group and period in serum calcium and phosphorous were not significant whereas, the group and period effect was significant but interaction effect of group and period were not significant in serum glucose concentration. Estrus induction rate was 90% with overall conception rate of 32.4%. Hence, it may be concluded that MLT supplementation restored cyclicity resulting in improvement in conception rate without significantly altering serum calcium, phosphorous and glucose concentration in summer anestrus buffaloes.

This study was conducted to evaluate the protective effects of melatonin against fluoride-induced oxidative stress-mediated haematological and biochemical changes in rat at high altitude. Adult male Wistar rats (6) were given the basal diet and drinking water ad lib. for first 7-days which was considered as the control period. Thereafter, they were exposed to NaF (@ 50 ppm) per-oral through drinking water for the next 14 days followed by melatonin treatment (@ 15 mg/kg BW, p.o.) for the next 14 days. The result showed induction of oxidative stress during NaF treatment alone, which caused significant increase in alkaline phosphatase (ALP), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) activity, and % inhibition of DPPH, MDA, and water intake. Whereas, total antioxidant capacity (FRAP) and body weight gain were significantly reduced during NaF exposure. Haemogram analysis indicated significant decrease in haemoglobin, packed cell volume, erythrocytes, lymphocytes, platelets count, whereas increase in MCH, monocytes, neutrophil, and eosinophil during NaF exposure. However, melatonin administration after 14 days of fluoride treatment resulted in significant amelioration of adverse changes occurred in different blood-biochemical parameters and also increased the total antioxidant status. Notably, the body weight gain improved during melatonin administration. These findings indicated induction of oxidative stress-mediated adverse change in haematology and biochemical parameters, and amelioration effect of oral dose of melatonin in rats under high altitude stress condition. Hence it can be concluded that melatonin acts as a potent antioxidant agent, which may be orally supplemented for amelioration of fluoride-mediated oxidative stress even under prevalent high altitude stress.

The donkeys of Ladakh region of Jammu and Kashmir, are well adapted to the cold, arid and hypoxic conditions of this region. The genomic DNA, isolated from 25 blood samples collected from these donkeys, were amplified by PCR using FAM and HEX labeled primers and resolved for alleles on automatic DNA sequencer. Total 20 loci of the horse origin were tested and only 13 loci gave scorable results. Rest of the loci either did not amplify well (HMS3, HMS7, ASB17 and COR22) or showed less than four alleles (HMS5, HMS6, HTG4), in the studied population. At the 13 loci included in the final analysis, the PCR product size ranged from 79â€“85 bp at locus HTG6 to 257â€“275 bp at locus COR18. The observed number of alleles varied from 4 (HTG15, HTG6, HTG10 and VHL20) to 9 (HTG7 and COR71) with a mean of 5.92Â±1.80. The observed heterozygosity ranged from 0.44 (VHL209) to 0.90 (AHT5) with a mean of 0.76Â±0.13. The mean genetic diversity estimate (FIS) was â€“0.076. The cumulative exclusion probability (PE) of these loci was 0.999838 indicating their suitability for parentage testing in these donkeys. The sign test, standardized differences test, the Wilcoxon test using the allelic frequency data under two phased mutation model and sequential mutation model at the studied loci as well as normal â€˜Lâ€™ shaped distribution of the allelic frequency indicated the absence of any recent genetic bottleneck in donkeys of Ladakh region. When these donkeys were compared to Spiti donkeys of Himachal Pradesh and Brown type donkeys of Andhra Pradesh on the basis of allelic frequency data at these loci, they showed Neiâ€™s minimum genetic distances of 0.115 and 0.165, respectively, from these population.

Published: December 2022

This study aimed to determine the efficacy of exogenous fibrolytics enzymes (EFE) to create a synergy with Saccharomyces cerevisiae (SC) or essential oil (Eucalyptus globulus) (EO) to promote the in vitro ruminal fermentation and digestibility of wheat straw (WS). The EFE was a mixture (1:1, v/v) of Î²-1, 3-1, 4-glucanase and endo-1,4-Î²-D-xylanase produced by the Trichoderma longibrachiatum. The WS was supplemented with EFE (EFE1=1, EFE2=2 Î¼l/g DM), SC (SC1=0.5, SC2=1 mg/g DM), EO (EO1=30, EO2=60 Î¼l/g DM) and the combinations EFE1+EO1, EFE1+EO2, EFE2+EO1, EFE2+EO2 and EFE1+SC1, EFE1+SC2, EFE2+SC1, EFE2+SC2. Compared to the control, both EFE and SC alone or in combination, improved the rate and the extent of WS fermentation. The potential GP improved only with EFE2, SC1, and EFE2+SC2 by 31.7, 24.9, 37.4% and the rate Rmax by 36, 59.2 and 55.2%, respectively. The organic matter digestibility and the energetic use of WS improved with the highest doses EFE2 and EFE2+SC2. While the EO alone or combined with the EFE had a depressive effect on all fermentation and digestibility parameters. The EFE seems to be more beneficial for the fermentation and digestibility of WS than when it was combined with SC or EO. Therefore, there is no synergetic effect between EFE and SC or EO with the used doses on fibrous by-product like wheat straw.

Lactating Large White Yorkshire sows (18) with their litters were selected for the study and were divided into three groups (T1, T2, T3). In T1 and T3 groups, piglets were weaned at day 24 and 28. In group T2, heavier half of the litters were weaned at day 24 and remaining half were weaned at day 28. The piglets were reared up to 70 days of age and their performance was recorded. The result revealed that average body weight (kg) at day 70 and the ADG (g) from 1st to 10th week differed non-significantly among the groups. Nonsignificant difference was observed in pre-weaning, post-weaning and overall ADI among the different weaning groups. FCE from weaning to 10th week was similar among the different weaning groups. In conclusion, the whole litter or split litter weaning at day 24 or 28, had no effect on body weight gain, average daily gain, average daily feed intake and feed conversion efficiency of piglets. The findings may be helpful to develop managemental strategies for early weaning of piglets in Indian farm conditions.

Published: December 2022

The present study analyses energy flows through livestock production system and works out energy audit in selected mid-altitude villages in the Pithoragarh district of the Kumaun Division of Uttarakhand lying in the Central Himalayan region. The livestock population (converted into livestock units) consumed 144638094.9 kJ/day or 52792904649 kJ in a year and, in turn, produced 8490715137.07 kJ in a year through dung, 2056277724 kJ though milk, 60704289.30 kJ through calf crop and 6416.35 kJ by means of draught power supply to various agricultural operations. The gross energy produced by livestock was 10607703567 kJ/year. Proportion of the output energy from dung (80%) was much more than from milk (19%). Contribution of calf crop and draught animal power (DAP) was minimal compared to the overall energy. The gross energetic efficiency of livestock production was 20.09%. Energy for maintenance and growth available for livestock was 25.15%. The study reveals that a substantial proportion of energy in a mountain agro-ecosystem flows through livestock.

Bovine PRL gene is considered one of the important hereditary components of milk productivity, thus seems to be an excellent candidate gene for milk production traits. The study was conducted to study the distribution pattern of allelic variants at the prolactin-RsaI locus in 210 indigenous cattle of north east India (viz. Manipur, Mizoram, Nagaland, Tripura, Asom and Meghalaya,) and crossbred cattle of Mizoram. PCR-RFLP genotyping of a 156 bp fragment of prolactin (PRL) in exon 3 revealed two different allelic variants. The predominant genotype (s) were AB (0.40) and BB (0.40) in indigenous cattle of Manipur, BB in Mizoram (0.57), AB in indigenous cattle of Nagaland (0.50) and Meghalaya (0.63). Whereas in Tripura and Asom indigenous cattle, AA was the most common genotype (0.40 and 0.60). However, AB (0.80) was markedly higher in crossbred (HF Ã— indigenous) cattle. All the six indigenous cattle populations conforming to equilibrium indicated lack of selection pressure for PRL gene in these cattle population. The most frequent allele was A allele in the indigenous cattle of Nagaland (0.55), Tripura (0.55) and Asom (0.70) and B allele in indigenous cattle of Manipur (0.60) and Mizoram (0.73). Whereas, in Meghalaya indigenous and crossbred cattle, both alleles were present in equal frequencies. The findings of differences in the distributions of allelic and genotype variants of PRL-RsaI locus among the indigenous cattle populations of six states of north east India, suggested the presence of scope for genetic selection for milk production traits.

Published: December 2022

Contagious ecthyma, also known as scabby mouth or Orf, is a zoonosis, which is caused by the Orf virus (ORFV). Human contact with infected animals can cause cutaneous lesions. To prevent and control ORFV effectively, rapid detection method is very important and highly needed. Real-time quantitative fluorescence PCR (qPCR) assay is considered as a rapid techonology to detect ORFV, and has been used for clinical diagnosis and epidemiological investigation. In present study, we developed a TaqMan-based qPCR assay for detection of ORFV. Beacon Designer 7.9 was used to design specific primers and probes were based on the ORFV020 gene sequence of the virus (GenBank Accession No. KF666563.1). The method had no cross-reactions with other common bacteria and viruses, was highly specific; the sensitivity test result showed that it could detect 10 copies of ORFV genomic DNA, and was more sensitive than conventional PCR. Both intra- and inter-variabilities were less than 2%, indicating the high stability and repeatability of the method. Additionally, 99 clinical samples from sheep and goats with suspected contagious ecthyma were tested using the developed assay and conventional PCR. The results showed that the developed assay was more sensitive and faster than conventional PCR. It can be concluded that the assay was suitable for routine detection of the ORFV and the epidemiological investigation.

Published: December 2022

This study examined the comparative effect of incorporation of improved canola quality and high glucosinolates rapeseed mustard oil cake (RMC) in the supplement of crossbred cows on metabolic profile, thyroid hormones, milk yield and quality of milk. Lactating crossbred cows (18) were randomly divided into three groups of six each in a completely randomized design and allocated in three dietary supplements, viz. SBM, RMC and CM containing soybean meal (SBM), rapeseed mustard cake (RMC) and canola meal (CM), respectively as a major protein source for a period of 90 days. Daily intake of total dry matter and green fodder was comparable irrespective of dietary treatments. The supplement intake (kg/d) was significantly lower in the cows that were given RMC supplement compared to those given either SBM or CM supplement. Incorporation of CM in the supplement significantly increased daily and total milk yield (kg) as compared to RMC group. The milk thiocyanate level was significantly higher in RMC followed by CM and SBM groups. Blood-biochemical profile except significantly higher lactate dehydrogenase in RMC group remained comparable at different periods. Serum thiocyanate was significantly higher in RMC followed by CM and SBM. Serum T3 and T4 hormone levels were significantly lower in RMC fed group as compared to CM and SBM groups. It can be concluded that feeding of canola quality RMC (GSC5/6) may be used as complete replacement of soybean meal without any adverse effect on metabolic profile, thyroid hormones, milk quality and yield in crossbred cows.

Availability of green fodder with improved quality to animals is the key to success for sustainable livestock production. It is difficult to maintain the health and milk production of the livestock without supply of the quality green fodder. Therefore, the study was carried out to evaluate the forage quality of maize and legumes as influenced by varying intercropping combinations. This experiment was laid out in randomized complete block design (RCBD) with seven treatments consisting of three different forage crops, viz. maize, cowpea and guar sown in sole as well as in 1:1 and 2:1 intercropping combinations of forage cereal with legume crop components in three replications. Experimental results showed that the highest dry matter yield (94.89 q/ha) was obtained in maize+ cowpea (2:1) intercropping combinations. The quality parameters of different forage crops, viz. Organic Matter, Crude Protein, Ether Extract, Ash Content, Neutral Detergent Fiber, Acid Detergent Fiber, Acid Detergent Lignin, NDICP and ADICP were influenced significantly and favourably with inclusion of both legumes. Among intercropping combinations Maize: legume (1:1) was better over Maize: legume (2:1) and sole maize. The CP, EE and Ash yield were influenced significantly and maximum value were observed 10.74, 1.99 and 9.4 q/ha, respectively in forage maize+ cowpea (2:1) ratio. Among the different forage crops, the fiber fractions were observed minimum in (1:1) intercropping ratio of maize with legume components as compares to their sole component as well as (2:1) intercropping combinations. The insoluble crude protein content was found minimum in (1:1) intercropping combination and influenced significantly with their respective (2:1) or sole crop.

Data on birth weight and mortality pattern of Zebu (Sahiwal and Tharparkar) and Crossbred (Holstein Friesian Ã— Tharparkar) cattle spread over 16 years were utilized to analyze the causes of calf mortality and to study the effect of non-genetic factors on calf mortality. Calf mortality was higher in crossbred (27.7%) compared to either Sahiwal (20.7%) or Tharparkar cattle (11.9%). Age group wise analysis revealed maximum mortality within one month age in Zebu cattle, and during 1â€“3 months age in crossbred cattle. Mortality was higher in calves born during winter, summer and rainy seasons in Sahiwal, crossbred and Tharparkar, respectively. Mortality was higher among male calves compared to female calves. Significantly higher proportion of Sahiwal calves died due to respiratory problems, while general debility was the major reason for calf mortality in crossbred and Tharparkar cattle. Season of birth had highly significant influence within one month age in Sahiwal and crossbred cattle. Influence of all the non genetic factors on calf mortality at various age groups was found to be non significant in Tharparkar cattle. It is inferred that calf mortality was higher in crossbred compared to Zebu cattle and the effect of season of birth and birth weight had a significant effect on calf mortality during first three months age. Among the several causes, respiratory problem was a significant reason for the calf mortality.

Published: December 2022

A total of 1207 pedigreed progenies of 50 sires and 177 dams of a selected line of Rhode Island Red chicken were investigated in two hatches at ICAR-Central Avian Research Institute for genetic analysis of their body weights. The genetic and non-genetic parameters of chick weight at day-old age and body weight at different ages were estimated using least squares analysis of variance. The heritability and correlation coefficients were estimated for different traits using paternal half-sibs. The mean sum of squares for sex component of variance was significant for body weights at third week of age onwards, males being heavier throughout the ages. Sire component of variance was also significant for chick weight and different body weights except the estimates at 6th and 16th week of age. Hatch component of variance was highly significant for chick weight and body weights upto 12th week of age. Regression effect of chick weight on subsequent body weights was found significant specifically for body weights from 1st week onwards to 20th week of age. The heritability estimates were 0.775±0.151 for chick weight, 0.303±0.09 to 0.44±0.142 for body weights from 1st week to 12th week of age, and 0.258 to 0.248 for body weights from 16th week to 20th week of age. The estimates at lower age could be used in selection programme based on the flock's own performance to improve those traits. The genetic and phenotypic correlation coefficients were positive and highly significant in most of the cases. The corresponding estimates ranged from 0.044 to 0.990 and 0.020 to 0.788, and these coefficients could be combined in construct of standard selection indices for optimum growth in body weight that might be adopted in future breeding strategy for this RIR chicken genotype.

Published: December 2022

Worldwide, global databases on fishes lack fish diversity information at regional scale of a country, which has fascinated many fishery workers to know the regional scale fish diversity. Databases are essential part of the biodiversity science and have been used widely in the biological research. The present study discusses development, services and utility of the database application (UPFBase) providing information on the freshwater fish biodiversity of Uttar Pradesh. To develop UPFBase, data on the fish biodiversity of this region was compiled from different sources that include primary data generated from different projects and secondary data from published literatures. The collected data were screened and then digitized. Microsoft ACCESS relational database and Visual Basic language technologies were used for designing and implementing the standalone database application with the data management capability. Presently, UPFBase provides taxonomy, synonyms, local name, common name, morphology, biology, distribution, habitat, economic importance, conservation status and other fishery information on 129 fishes belonging to 11 orders and 27 families. UPFBase is user friendly and provides ease in working through search, query and action command button tools. It can easily be deployed on the mobile storages devices like CD-ROM, Pen drive, PCMCIA etc and can be installed on any Windows based Intel x86 machines. This version of UPFBase was built for countries, where computational hardware and software resources are in scare and it is expected that it might play imperious role in knowing and managing the indigenous fish diversity for decision making and posterity.

Abstract
Nickel slag is an industrial waste that physically in the form of natural rock which allows it to be used as a coarse aggregate material in mixing high strength concrete. The use of nickel slag as an aggregate in the concrete production is expected to have a positive impact on the compressive strength of concrete, but also to become an alternative solution in environmental impacts problem. By partially substituting nickel slag for coarse aggregate (crushed stone) with variations of 20%, 40%, 60%, 80% and 100%, a contribution model is obtained which tends to follow a polynomial equation to the degree of two. Based on this model, the optimum percentage of nickel slag is 23.93% with a maximum compressive strength of 46.96 MPa.
Keywords: Coarse aggregate, maximum compressive strength, optimum nickel slag.

As I write this editorial, the war going on the air space and on the field and over communication (invasion or the special military intervention, in the words of the Russian government in Ukraine by Russia continues. A situation that would be unthinkable to happen in the 21st century where humanist values seem to follow a path of increasing strength; at least in most continents, although the democratic political system is largely a minority in the world; dictatorships or autocracies are dominating the political landscape, especially in Asia, the Middle East and Africa. We must not forget this! I believe that even analysts and experts in international relations, including the ones in the countries with sophisticated espionage systems like USA or Great Britain, would be far from predicting a conflict of this intensity and negative impact on humanity: more than three million refugees and thousands of deaths (both amongst military and civilians) in both countries.
Local Journalism without Journalists? Metric Media and the Future of Local News
Authors: Royal Asa , Napoli Philip M.
Published: December 2022

Over the past 15 years, more than 2000 newspapers in the United States have shuttered, leaving the country pockmarked by news deserts. As local newspapers have closed, networks of online local news sites have risen to replace them. We assess the largest network of this kind, Metric Media, by scraping and analyzing the content of its 999 outlets over a 2.5-month period. We find that Metric Media prioritizes the publication of state and national partisan content at the expense of local news, algorithmically generates most of its content, and fails to live up to its mission of democratizing and revitalizing local journalism.

Discourse analysis is a field of study that examines the meanings conveyed by a person's words, sentences, or other utterances, whether they are spoken out or written down. According to Fairclough, discourse has three outcomes. Discourse, in the first place, aids in the formation of social identity and subject position. Both discourses contribute to the formation of interpersonal relationships. Thirdly, discourse has a role in the formation of knowledge and belief structures. Particularly in the Industrial Revolution 4.0 Era, when the internet has evolved into one of the most fundamental human necessities, social media development is accelerating. Social engagement takes place not only in person, but also frequently online or virtually. The public is quite fond of a number of social media sites, including Facebook, Twitter, Instagram, Pinterest, Tiktok, and others.

Along with the times and technology, the way of preaching has also changed. Compared to preaching through speech, currently preaching through writing is more urgent and effective to do, namely preaching using social media such as the internet and writings on social media that contain da'wah messages. The advantages of preaching with this model do not make the preaching material disappear even though the preacher, or the writer has died, as the expression of His Majesty Rasulullah SAW, "Indeed the ink of the scholars is better than the blood of the martyrs."  However, the purpose of da'wah with this model will be realized if it is supported by effective media. This means that in the da'wah process the preachers do not only present material verbally, but also must deliver their da'wah material via social media so that the material can be read anywhere and anytime, as is the case with the role of social media today. If we look at da'wah at this time, it is necessary to have a critical and in-depth evaluation, because the styles, models, methods and media used also influence the implementation, direction, dynamics and implementation of da'wah. Given the importance of social media as a means of preaching, it is necessary to have specific strategies, methods and approaches for preachers in preaching regarding the use of social media as a means of conveying messages of Islamic da'wah. This journal will contribute thoughts to become an inspiration for preachers to use social media as a means of conveying da'wah messages.

Por eso, suelen ser abordados por estudios multidisciplinares, entre los que destaca la psicología forense, quien aporta valiosos marcos teóricos que intentan explicar el papel de la identidad, las relaciones sociales y los estilos de crianza de los infractores. No obstante, todos esos estudios se han concentrado más en las sociedades urbanas. Los municipios regidos por usos y costumbres, que en Oaxaca, México, alcanzan aproximadamente al 80%, no han merecido la misma atención por parte de la comunidad científica. Teóricamente, esos sistemas de organización comunitaria están basados en identidades originarias sólidas, relaciones sociales estrechas y estilos de crianza tradicionales. Por lo anterior, se realizó una investigación con enfoque cualitativo y exploratorio para identificar qué estilos de crianza recibieron tres jóvenes delincuentes del municipio de San Lorenzo Cacaotepec, Oaxaca, México, quienes cometieron faltas menores en este municipio. Los principales hallazgos sugieren que, contrario a lo supuesto, las vías de comunicación entre los miembros de la familia son escazas, hay ausencia de uno de los progenitores y los grupos externos a la familia, como los equipos para practicar deporte, son factores de riesgo para ingerir sustancias prohibidas. Lo anterior sugiere que los municipios que se rigen por usos y costumbres mantienen un sentido de comunidad y tradición con efectos políticos, pero no familiares ni personales. En este sentido, no habría motivos para considerar que se cometen menos delitos menores en estas comunidades, que en las sociedades urbanizadas.

This paper discusses methodological aspects by illustrating the fi rst products of a researchproject developed as part of a collaboration agreement between the DICAr - Departmentof Civil Engineering and Architecture of the University of Pavia and the enterprise GEAs.r.l. Archaeology, for the documentation of the archaeological excavations in the former SantaMargherita Institute in Pavia (Italy). The activities, carried out by the experimental laboratoriesDAda-LAB and PLAY, regarded the documentation of the archaeological evidences, datingback to the 4th century AD, brought to light by the interventions of conversion and remodellingof the historical and architectural complex. The need to produce documentation apparatus tosupport the excavation activities is boosted by the fragility of the archaeological site, apparentlymeant to disappear to allow space for the construction of an underground car park.The research aims to develop a methodology for the organisation of the data acquired in themultiple excavation campaigns, the production of databases useful to archaeologists for thechronological interpretation of the excavation, the detection of archaeological emergencies andthe development of an information system that combines models and databases. Since March2022, data acquisition campaigns have been undertaken to progressively survey the phases ofexcavations. Data sheets were then developed for stratigraphic units and deposit units, andan effective GIS system was developed to represent the complex nature of the site by makingclear the relationships between the stratigraphic units. The fi rst results of the research outline amethodological process that leads to the development of a digital ‘container’ in which it becomespossible to include the data collected during the campaign by reducing the time gap betweenacquisition, recording, processing and synthesis of information.

Published: December 2022

Áreas de la Amazonía colombiana han sido cada vez más antropizadas y su recuperación carece de tecnologías sostenibles adaptadas a la realidad local. Los métodos de priming, como la inmersión en agua, pueden ser una alternativa sostenible para el manejo forestal, en condiciones de vivero. Así, el objetivo de esta investigación fue probar el uso de priming en semillas de tres especies nativas de importancia ecológica y social en la Amazonía colombiana (Inga bourgonii (Aubl.) DC., Zygia longifolia (Humb. & Bonpl. ex Willd.) Britton & Rose y Guarea guidonia (L.) Sleumer), para promover el vigor. Para ello, se evaluó el efecto de la inmersión en agua durante 24 horas sobre la germinación y emergencia de semillas de I. bourgonii, Z. longifolia y G. guidonia en dos experimentos separados (siembra en arena y rollos de papel), con la visualización de variables de germinación y vigor. Se observó germinación superior al 89% en 24 días de evaluación para las semillas de las especies evaluadas, en ambos experimentos. El tratamiento de inmersión en agua disminuyó el porcentaje de germinación y emergencia de las semillas de I. bourgonii y Z. longifolia, durante todo el período experimental. En cambio, para G. guidonia se observó 95% de germinación en semillas sumergidas en agua durante 24 horas. Las variables analizadas en relación con los tratamientos con inmersión en agua por 24 horas o no, fueron similares para ambos experimentos (p>0.05). Estudios adicionales con I. bourgonii, Z. longifolia y G. guidonia en vivero serían importantes para impulsar programas de reforestación en áreas degradadas de la Amazonía colombiana.

Published: December 2022

Con el propósito de determinar el estado del ecosistema de un área en regeneración asistida en el Cerro Espíritu Santo en Naranjo, Alajuela, se realizó un estudio del estado de sucesión ecológica en 2021. Se establecieron aleatoriamente 12 parcelas en tres sectores seleccionados de acuerdo con el tiempo de intervención, donde se caracterizó la vegetación leñosa con un DAP mayor o igual a 10 cm. Además, se identificaron las barreras que obstaculizan el proceso de regeneración junto a los mecanismos facilitadores del mismo. Se identificaron 22 especies en total, en su mayoría nativas y con un predominio de la familia Fabaceae. Nueve de estas especies también se encontraron en el ecosistema de referencia. Se calculó el Índice de Valor de Importancia (IVI) para identificar a las 10 especies más importantes en la estructura del ecosistema, siendo Ficus sp. la de mayor importancia. Se calculó el promedio del DAP por especie para determinar el desarrollo de las especies en cada sector y se clasificaron las especies en gremios ecológicos, a fin de definir el estado de sucesión ecológica. Los tres sectores mostraron dominio de heliófitas durables, mientras que el sector 1 mostró un mayor desarrollo de especies y un incremento en la cantidad de esciófitas parciales, lo que se deduce en un mayor avance sucesional. Finalmente, se estimó la diversidad de especies y el desarrollo de individuos como indicadores sucesionales para dar seguimiento al proceso de rehabilitación ecológica del ecosistema.

Hay creciente preocupación sobre problemas ambientales, tales como: cambio climático, agua potable escasa, pérdida de biodiversidad y, además, existe desconocimiento de las valoraciones, actitudes y comportamientos. La pregunta de investigación se basó en las Representaciones Sociales acerca del ecoturismo comunitario, problemas ambientales y relaciones con educación ambiental, de acuerdo con ello, el objetivo fue identificar las Representaciones Sociales en ese contexto sobre el territorio de cinco corregimientos de la zona rural de Florencia-Caquetá, Colombia, durante los años comprendidos entre 2019-2022. La metodología tiene carácter proyectivo, tipo mixto, método hermenéutico y las técnicas utilizadas fueron encuesta, entrevista semiestructurada, grupos de discusión con representantes del sector educativo, comunitario, político, académico-investigativo ambiental, turístico, empresarial y desplazados. También, se implementó la técnica de triangulación y análisis de contenido. El supuesto teórico de esta investigación considera a las Representaciones Sociales como una de las estrategias para el fomento del ecoturismo comunitario. En los resultados, el núcleo de las Representaciones Sociales del ecoturismo fue: territorio y conocimiento de habitantes y turistas. Los elementos periféricos fueron: la investigación, participación comunitaria y educación ambiental multidisciplinaria para articular campos de conocimiento como: cultura, historia, biodiversidad, inglés, administración, derecho y marketing. Como conclusión, la educación Ambiental es piñón del ecoturismo comunitario como oferta de formación en todos los niveles educativos para conocimiento de las dimensiones del territorio, con participación, articulada entre habitantes del territorio, academia, Estado y empresarios. El conocimiento de RS es esencial para el cambio actitudinal en la responsabilidad con el ambiente. La investigación y participación comunitaria se nutren de la educación ambiental con carácter multidisciplinario. Es de resaltar la necesidad de un papel más protagónico de la academia para el apoyo a las comunidades interesadas en el ecoturismo comunitario.

Unlike the North-East of Aceh region was previously an industrial zone and shifted to the service sector and agriculture. The central-southeast area remains in the plantation zone. Initially, the south-west region consisted of 2 regencies, namely the districts of West Aceh and South Aceh. Then in 2002, this region split into 4 districts namely Nagan Raya, Aceh Jaya, Simeulue and West Aceh districts. This study aims to analyze the potential of the regional superior sector in West Aceh Regency and its expansion area using Location Quotient analysis, or abbreviated as LQ, towards a sustainable economy in the new normal era. The data used is secondary data sourced from the central statistical agency of each district and province of Aceh. The gross regional domestic product data for the period 2010-2020 is 17 sectors. The results showed that the highest LQ value in Simeulue district was 2.18 for the government administration sector, then 1.51 for the agriculture, forestry and fishery sectors. For information, this district excels in lobster cultivation. Next is Nagan Raya district with an LQ of 2.88 in the mining/excavation sector and 1.52 in the agriculture/plantation sector. This value is obtained because this district excels in mining C and oil palm plantations. Then Aceh Jaya with an LQ of 1.81 in the construction sector and 1.55 in the transportation sector because this area is superior in terms of tourism. Finally, Aceh Barat district with an LQ value of 1.59 for the financial/information services sector. Meanwhile, in the agriculture/forestry sector it was 1.17 because this district excels in financial services and is the largest city on the south west coast of Aceh. The leading sectors above must still be managed properly, especially local potentials while still paying attention to a sustainable environmental economy. This is not an exaggeration considering that in this new normal era, the economy must continue to rise even during the COVID-19 pandemic while still adhering to health protocols.
