A educação profissional e tecnológica e a formação docente: uma trajetória de transformações e lutas
Authors: Urnau Simone , Urbanetz Sandra Terezinha
Published: September 2022

O presente artigo tem por objetivo discutir a formação docente para a Educação Profissional e Tecnológica (EPT) a partir de um resgate histórico, em suas primeiras manifestações e os desafios enfrentados neste momento. Este arcabouço se constrói no intuito de descortinar a realidade evidenciada em discussões que tratam da formação de professores no contexto da EPT que, desde a sua formação inicial, apresentam-se distantes de concepções teóricas que discutam o mundo do trabalho e a sua intrínseca relação com a educação. Somado a isso, insuficientes ainda são as políticas públicas para a adequada formação docente continuada, intensificadas nesse momento em nosso país com as políticas de desvalorização da educação de maneira geral. Além disso, as ações ofertadas, em sua maioria, são caracterizadas como aligeiradas e fragmentadas para um diagnóstico de constante necessidade por qualificação e valorização desses profissionais. É neste cenário que o docente, compreendido como um trabalhador que carece de uma sólida formação, está desafiado cotidianamente a garantir uma construção humana sólida e integral aos seus estudantes, que supere o mero atendimento às necessidades do mercado de trabalho, ainda mais explorador diante do cenário histórico.
Thermodynamic factor and vacuum crystallization
Authors: Semenov Evgeniy , Slavyanskiy Anatoliy , Mitroshina Daria , Lebedeva Natalya
Published: September 2022

Sucrose crystallization depends on various thermal phenomena, which makes them an important scientific issue for the sugar industry. However, the rationale and theory of sucrose crystallization still remain understudied. Among the least described problems is the effect of time and temperature on the condensation rate of sucrose molecules on crystallization nuclei in a supersaturated sugar solution. This article introduces a physical and mathematical heat transfer model for this process, as well as its numerical analysis.

The research featured a supersaturated sugar solution during sucrose crystallization and focused on the condensation of sucrose molecules on crystallization nuclei. The study involved the method of physical and mathematical modeling of molecular mass transfer, which was subjected to a numerical analysis.

While crystallizing in a vacuum boiling pan, a metastable solution went through an exothermal reaction. In a supersaturated solution, this reaction triggered a transient crystallization of solid phase molecules and a thermal release from the crystallization nuclei into the liquid phase. This exogenous heat reached 39.24 kJ/kg and affected the mass transfer kinetics. As a result, the temperature rose sharply from 80 to 86 °C.

The research revealed the effect of temperature and time on the condensation of solids dissolved during crystalline sugar production. The model involved the endogenous heat factor. The numerical experiment proved that the model reflected the actual process of sucrose crystallization. The obtained correlations can solve a number of problems that the modern sugar industry faces.

Authors: Dinkar Anju , Singh Jitendra , Patel Nitish Kumar , Bhavya J  , Dewangan Ankita , Kumar Nilesh , Kumar Kalish
Published: September 2022

Background:

Tuberculosis is one of the major infectious diseases of mankind and remains a
significant health concern, especially in developing countries. Clinical manifestations of TB are broad
and sometimes very challenging for clinicians to diagnose early. Tuberculous psoas abscess was generally
secondary to spinal tuberculosis or direct extension from adjacent structures in immunocompromised
individuals, but tuberculous psoas abscess in the immunocompetent state is very infrequent. In
addition, pancytopenia and new onset neck swelling simultaneously make this presentation a very unusual
clinical entity in tuberculosis.

Case Presentation:

We now present a case of a 21-years-old, unmarried, otherwise healthy girl presented
with fever, lower abdominal pain and weight loss for two months. She also noticed painless
neck swelling for 15 days. She later had a tuberculous left sided psoas abscess with pancytopenia and a
cold abscess on the left side of the neck with no sign of any other apparent focus, according to the evidence.
Diagnosis of disseminated TB without lung involvement was established and ATT was started.
The outcome was successful on follow up.

Conclusion:

Among the broad spectrum of atypical manifestations of TB, this case report draws attention
to its rarity, diagnostic challenge and awareness of the clinical spectrum, especially in developing
countries.
Evaluation of Remineralizing Effects of CPP-ACP and Nanohydroxyapatite on Erosive Lesions of Enamel in Deciduous Teeth After Exposure to Acetaminophen Syrup: An in vitro Study
Authors: Hadidi Fateme , Haghgoo Roza , Kameli Somaye , Ahmadvand Motahare
Published: September 2022

Background:

Oral pediatric liquid medications are commonly used in children who suffer from chronic diseases. Due to acid components in their formulations, these medications may possess a high erosive potential to dental tissues. Erosion is one of the major causes of degradation and demineralization of the enamel. If demineralization causes are not inhibited, it progresses and completely degrades the enamel. So, the dentin is exposed, and, finally, the pulp will be engaged in the process.

Aim:

This study aimed to evaluate the remineralizing properties of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and nanohydroxyapatite on erosive lesions caused by acetaminophen syrup intake in vitro.

Methods:

The microhardness of 34 healthy human primary molars was determined prior to and following a seven-day, three-times-a-day, one-minute exposure to acetaminophen syrup. The teeth were then randomly divided into four groups and were immersed in artificial saliva, fluoride gel, nano-hydroxyapatite, and CPP-ACP for 10 minutes. Then, their final microhardness was measured, and repeated-measures ANOVA analyzed the data.

Results:

Enamel microhardness in two groups decreased after exposure to acetaminophen syrup and increased after applying remineralization agents, CPP-ACP, and nano-hydroxyapatite. The two groups did not show significant differences in terms of microhardness increase (p-value=0.141).

Conclusions:

According to the findings of this study, CPP-ACP and nano-hydroxyapatite can improve the microhardness of enamel, which has been reduced as a result of exposure to medicinal syrups.
A Narrative Review of the Disenfranchisement of Single Mothers in Highland Ecuador
Authors: Pino Gavidia Lisbeth A. , MacDermid Joy C. , Brunton Laura , Doralp Samantha
Published: September 2022

Background:

The Andean South American country of Ecuador presents social challenges that contribute to inequities. The social determinants of health have impacts on the physical, psychological and social health of individuals across all societies. Ecuador is an example of how the interactions of gender roles and social determinants of health impact the health of single mothers and their children.

Methods:

A retrospective historical literature review was conducted on gender role expectations within the rural context Ecuador to inform future public health strategies and health interventions.

Results:

Gender inequality contributes to higher rates of single parenting, child labour, and migration. Food insecurity and poverty are affected through the interface of economic hardships and rural agricultural livelihoods.

Conclusion:

The disenfranchisement of poor rural women in Ecuador is deeply rooted in historical gender discrimination, societal attitudes, and institutionalized gender bias that incur onto the society as a whole in terms of becoming less protectors and producers of human resources. The health of single mothers and children living in poverty and their ability to create a healthy family environment will not improve until women explore their productivity and creativity amid social tensions and livelihood struggles.

Published: September 2022

This study aimed to determine the performance of eggs and blood cholesterol of laying hens fed with fragrant pandan leaf flour (Pandanus amarylifolius Roxb). A total of 200 laying hens were used in the study, with 5 treatments and 5 replications, each filled with 8 chickens. The research design used was completely randomized (CRD), and further analysis was conducted using Duncan's Multiple Range Test. Treatments given fragrant pandan flour were 0%, 1%, 2%, 3%, and 4%. This research was conducted for 8 weeks. Parameters included: ration consumption (g/head), ration conversion, egg weight (g), Hen Day Production (%), blood cholesterol (mg/ml), blood HDL (mg/dl) and blood LDL (mg/dl). Results showed that the use of fragrant pandan leaf flour up to 4% gave a very significant effect (P < 0.01) on conversion, hen day egg weight production, blood cholesterol, blood HDL, and blood LDL, but not significantly different (P > 0.05) on ration consumption. The study concluded that using up to 4% of fragrant pandan leaf flour increases egg production and reduces ration conversion, blood cholesterol, blood HDL, and blood LDL of laying hens and ration consumption and does not cause negative effects on the laying hens.

Published: September 2022

This study aims to describe changes in the agro-industrial activities of salted eggs in Brebes Regency during the Covid-19 pandemic, both in marketing and agro-industrial processes. This research was conducted from January to April 2021. A total of 135 active salted egg agroindustries located in 12 sub-districts of 17 subdistricts in Brebes Regency were applied in this study. The research sample was 50 industries determined by purposive random sampling, namely districts with the most significant number of salted egg agroindustries (Brebes, Bulakamba, and Warnasari Regencies). Respondents are the owners of salted egg agroindustries who were selected as samples. Primary data (marketing distribution of salted eggs and salted egg processing technology) were collected by interview using a questionnaire and observation. Secondary data were collected by recording related documents from the government and the Central Bureau of Statistics of Brebes Regency. Data on the distribution of egg processing technology was analyzed descriptively. During the Covid-19 pandemic, producers had difficulty obtaining raw materials during a pandemic which triggered a 59% decline in salted egg production followed by a decrease in demand. Changes in salting salted eggs did not occur during the Covid-19 pandemic despite a decline in production. Salted egg producers do not reduce the quality of the salting method. As many as 30% of salted egg producers produce a combination of original, grilled, and baked flavors.

ematological malignancies, which include leukemia, Hodgkin's lymphoma (HL), non-Hodgkin's lymphomas (NHL) and multiple myeloma, amount 6.6% of the global incidence of malignant ne-oplasms, and 4.7% in Russia. A significant number of studies indicate the involvement of envi-ronmental factors in the occurrence of hematological malignancies. The role of electromagnetic waves in the origin of NHL is indicated by data on the increased risk of developing them in occu-pations associated with electricity. Leukemia in children is positively associated with vehicle smoke. There are indications of a role in the emergence of HL of tobacco smoke. Previously, the authors established a links between the incidence of NHL and leukemia in cohorts of young chil-dren with the activity of the Sun, and in leukemia a correlation with the smoke of forest fires was also found. In this work has been investigated the relations between the trends in the incidence of hematological malignancies in the population of Russia in 1993-2018 with smoke and solar activity. There was a tendency towards an increase in the incidence of hematological malignancies (p<0.001) by 2.8% per year. The incidence of leukemia (p=0.004), NHL (p<0.001), and multiple myeloma (p<0.001) significantly increased. This trend is presumably related to the increase in the number of cars in the country. The incidence of HL, on the contrary, is characterized by a downward trend (p=0.019). A link was found between the activity of the Sun and the incidence of leukemia (r=0.708, p=0.010, lag 2 years), NHL (r=0.689, p=0.013, lag 2 years), multiple myeloma (r=0.657, p=0.020, lag 2 years) and LH (r=0.606, p=0.037, lag 7 years). The data obtained sug-gest a significant contribution of smoke and solar activity to the occurrence of hematological ma-lignancies in children and adults. Based on the role of environmentally related oxidative stress in oncogenesis, it is recommended for the prevention of hematological malignancies to consume a sufficient amount of vitamins, regularly include in the diet fresh vegetables, fruits, foods to stimulate autophagy and Transfer Factor.

This work is devoted to a comparative analysis of the assessment of radiation risks of medical diagnostic exposure of patients using a method based on the recommendations of the International Commission on Radiological Protection (ICRP) and the method presented in the methodological recommendations of Rospotrebnadzor (MR 2.6.1.0215-20). In the course of the study, the authors analyzed the results of calculations of the lifetime attributable risk of oncological mortality calculated by these methods. As an example, the procedure of a single passage of computed tomography of the chest organs without contrast was considered. In the first case, the risk value was calculated using the methodology of ICRP Publication 103 based on organ doses for the following ages of men and women: examination at 22, 27, 32, 37, 42, 47, 52, 57, 62, 67, 72, 77, 82 and at 87 years old. In the second case, the data given in the tables presented in the methodological recommendations were considered, but without considering hereditary effects. The analysis was carried out for two cases: when the difference between effective doses between computed tomography procedures did not exceed 30%, and when the difference was more than 30%. The authors of the work found that the difference in the risk assessment between the two methods exceeds 1.5 times for the age groups of 65 years and older, for men and women, if the effective doses are close. If the difference in dose between the two procedures was more than 30%, then a 1.5-fold difference in risks was observed in age groups 60 years and older. Risk assessment was performed with account of age and gender characteristics, as well as with the use of medical and demographic data of the Russian population.

Photodynamic therapy (PDT) is the effective method for the total eradication of some types of solid malignant neoplasms. The paper presents results of research on the effectiveness of PDT of the melanoma B-16 with the intraperitoneally injected novel Russian photosensitizer (PS) "Photoran E6". To assess the response of melanoma to PDT, the following indicators were used: tumor growth inhibition index (TGI,%), tumor regression rate (%), absolute tumor growth rate (K) in mice with continued neoplasia growth. To assess the proportion of peripheral blood cells and their morphological characteristics the therapy efficiency integrated health indicators were used: increase in life expectancy (ILE,%) of mice under study in comparison with the control and the proportion of cured animals on the 90th day after PDT. The results of the study demonstrate high antitumor efficacy of Photoran E6 for PDT of mouse melanoma. The observed changes in hemogram parameters and in leukocyte indices also indicate the effectiveness of the therapy, changes in the control samples indicate the spread of the malignant process, proliferative processes, impaired normal regeneration of blood elements, severe intoxication that cause destruction and degeneration of blood cells and drastic changes in the course of immune response.

Published: September 2022

The paper presents result of ab initio methods exploiting to calculate the molar extinction spectrum of some model clusters, the molecular hybrid C24H30 included. Based on the comparison of the calculation with the experimental spectra of the main allotropic modifications of carbon, the absorption maximum with an energy of ~6 eV in the absorption spectrum of highly tetrahedral amorphous carbon (ta-C) attributed to the π->π* optical transitions of electrons in a single aromatic ring. The edge sites of the ring covalently bonded with the sp3-hybridised carbon atoms of the amorphous matrix. The manifestation of a shoulder in the spectrum of the imaginary part of the refractive index of a film of highly tetrahedral amorphous carbon (ta-C), 4.6 eV, is assigned to π->π* optical transitions of clusters distorted with hybrid Stone--Wallace-like defect, also covalently bonded with the amorphous matrix. Keywords: interaction of light with matter, new forms of carbon, tetrahedrally coordinated amorphous carbon, Stone--Wales defect.

We calculate Fermi level position in bulk HgCdTe with cadmium fraction from 19 to 22% as a function of temperature for different concentrations of mercury vacancies forming double-charged acceptors with ionization energies of 11 and 21 meV for neutral and singly charged states respectively. The concentration of free carriers in the bands at different temperatures and the proportion of acceptor centres in different charge states are calculated as well. The results explain the fast temperature quenching of photoconductivity involving the vacancies states. It is also shown that in a p-type material conductivity dependence on temperature includes an exponential growth region with a characteristic energy much greater than a half of the bandgap at zero temperature expected for an intrinsic semiconductor. Keywords: narrow-gap semiconductors, HgCdTe, Fermi level, doubly charged acceptors.
Main effects of oxygen centers in A-=SUP=-II-=/SUP=-B-=SUP=-VI-=/SUP=- optics
Authors: Morozova N. K.  , Abbasov I. I.
Published: September 2022

On the basis of the studies carried out, it is shown in the work that the influence of oxygen on the optical properties of AIIBVI crystals is determined by three main effects. This is the formation of a system of bound excitons accompanying the presence of high oxygen concentrations at stacking faults --- a long-wavelength shift by hundreds of meV of the absorption edge, and the third effect is determined by the emergence of broadband "self-activated" SA luminescence in the near-edge region of the spectrum. This work introduces the concept of a non-uniform distribution of isoelectronic oxygen centers in the bulk of crystals, both due to their predominant segregation at stacking faults and in layer of stacking faults. To analyze the optical data, we used the capabilities of the method for constructing band models, which collects extensive and multilateral information about specific samples. A refined models of the CdS(O) and ZnSeSe(O) multizone with stacking faults is presented. The paper describes the conditions and the possibility of joint and separate observation of these features in the spectra of different crystals AIIBVI and using them to create lasers. Keywords: band model, bond excitons, additional absorption edge AAE, point defects, stacking faults, band anticrossing theory (BAC), laser effect.

Impact of an eHealth Smartphone App on Quality of Life and Clinical Outcome of Patients With Hand and Foot Eczema: Prospective Randomized Controlled Intervention Study
Authors: Weigandt Wanja Alexander , Schardt Yannic , Bruch Aimee , Herr Raphael , Goebeler Matthias , Benecke Johannes , Schmieder Astrid
Published: September 2022

Background

Chronic hand and foot eczema is a polyetiological dermatological condition. Patients experience pain, itching, and sleep disturbances and have a reduced quality of life. Skin care programs and patient education can improve the clinical outcome. eHealth devices offer a new opportunity to better inform and monitor patients.

Objective

This study aimed to systematically analyze the effect of a monitoring smartphone app combined with patient education on the quality of life and clinical outcome of patients with hand and foot eczema.

Methods

Patients in the intervention group received an educational program; attended study visits on weeks 0, 12, and 24; and had access to the study app. Patients in the control group attended the study visits only. The primary end point was a statistically significant reduction in Dermatology Life Quality Index, pruritus, and pain at weeks 12 and 24. The secondary end point was a statistically significant reduction in the modified Hand Eczema Severity Index (HECSI) score at weeks 12 and 24. This is an interim analysis at week 24 of the 60-week randomized controlled study.

Results

In total, 87 patients were included in the study and randomized to the intervention group (n=43, 49%) or control group (n=44, 51%). Of the 87 patients, 59 (68%) completed the study visit at week 24. There were no significant differences between the intervention and control groups regarding quality of life, pain, itch, activity, and clinical outcome at weeks 12 and 24. Subgroup analysis revealed that, compared with the control group, the intervention group with an app use frequency of fewer than once every 5 weeks had a significant improvement in the Dermatology Life Quality Index at weeks 12 (P=.001) and 24 (P=.05), in pain measured on a numeric rating scale at weeks 12 (P=.02) and 24 (P=.02), and in the HECSI score at week 12 (P=.02). In addition, the HECSI scores assessed on the basis of pictures taken by the patients of their hands and feet correlated strongly with the HECSI scores recorded by physicians during regular personal visits (r=0.898; P=.002) even when the quality of the images was not that good.

Conclusions

An educational program combined with a monitoring app that connects patients with their treating dermatologists can improve quality of life if the app is not used too frequently. In addition, telemedical care can at least partially replace personal care in patients with hand and foot eczema because the analysis of the pictures taken by the patients correlates strongly with that of the in vivo images. A monitoring app such as the one presented in this study has the potential to improve patient care and should be implemented in daily practice.

Authors: Sasseville Maxime , Barony Sanchez Romina H , Yameogo Achille R , Bergeron-Drolet Laurie-Ann , Bergeron Frédéric , Gagnon Marie-Pierre
Published: September 2022

Background

Interactive conversational agents, also known as “chatbots,” are computer programs that use natural language processing to engage in conversations with humans to provide or collect information. Although the literature on the development and use of chatbots for health interventions is growing, important knowledge gaps remain, such as identifying design aspects relevant to health care and functions to offer transparency in decision-making automation.

Objective

This paper presents the protocol for a scoping review that aims to identify and categorize the interactive conversational agents currently used in health care.

Methods

A mixed methods systematic scoping review will be conducted according to the Arksey and O’Malley framework and the guidance of Peters et al for systematic scoping reviews. A specific search strategy will be formulated for 5 of the most relevant databases to identify studies published in the last 20 years. Two reviewers will independently apply the inclusion criteria using the full texts and extract data. We will use structured narrative summaries of main themes to present a portrait of the current scope of available interactive conversational agents targeting health promotion, prevention, and care. We will also summarize the differences and similarities between these conversational agents.

Results

The search strategy and screening steps were completed in March 2022. Data extraction and analysis started in May 2022, and the results are expected to be published in October 2022.

Conclusions

This fundamental knowledge will be useful for the development of interactive conversational agents adapted to specific groups in vulnerable situations in health care and community settings.

In EMIR, rates of stroke/systemic embolism, major adverse cardiovascular events, cardiovascular death and major bleeding were 0.57, 1.07, 0.63 and 1.04 events/100 patient-years, respectively. In ROCKET-AF, these numbers were 1.7, 3.91, 1.53 and 3.6 events/100 patient-years, respectively. In the Spanish studies, rates of stroke and major bleeding were 0–1.8 and 0.22–4.2 events/100 patient-years, respectively. In XANTUS, rates of stroke, major adverse cardiovascular events and major bleeding were 0.7, 1.8 and 2.1 events/100 patient-years, respectively.
Conclusion:
Despite the fact that rivaroxaban is prescribed for elderly patients with a high thromboembolic risk, rates of outcomes remain low.

The objective of this study was to determine the impact of environmental temperature during subprimal transporton moisture loss, color, and tenderness. Cases of striploins (n=24) and sirloins (n=24) were placed on 2 pallets. Each pallet was loaded on a refrigerated truck prechilled to −2.2°C (−2.2FT) or 3.3°C (3.3FT) and transported for 12 h prior to arriving at the South Dakota State University (SDSU) Meat Laboratory. One subprimal was subset from each case for further analysis. Purge loss was measured prior to fabrication into eight 2.54-cm steaks. Steaks were overwrapped and packaged in modified atmosphere packaging prior to a second transport. Four steaks from each subprimal were placed on 1 of 2 pallets. Each pallet was placed on a prechilled refrigerated truck set at −2.2°C or 3.3°C. The steaks were transported for 12 h prior to returning to SDSU, subjected to case life analysis, and stored fresh or frozen. Steaks were evaluated for color, cook loss, purge loss, and Warner-Bratzler shear force. Data were analyzed as a split plot design with main effects of first transport temperature, second transport temperature, and aging day. Data from fresh and frozen product were analyzed separately. Purge loss was increased for 3.3FT sirloins compared with −2.2FT (P=0.0362). L* values for −2.2FT strip steaks were increased (P<0.0001) and purge loss decreased (P=0.0188) compared with 3.3FT steaks. L* values and fresh steak purge loss for 3.3FT sirloins were increased (P=0.0356 and P=0.0460, respectively) compared with −2.2FT steaks. These data indicate varied responses to temperature differences based on subprimal. Thus, a universal recommendation for all meat products could not be made. Further investigation into the impacts of transportation temperatures on various meat products is vital to optimization of the meat supply chain.

Tonality Analysis of Wind Turbine Noise Based on IEC Standard
Authors: Arivukkodi Dr. G
Published: September 2022

Abstract: The tonality is a notable factor during the development of wind farms. Tonality is a component of acoustic noise emission from the wind turbine which annoys the surrounding area of the wind farm. This paper focuses to evaluate the tonality of the wind turbine acoustic measurement data based on the standard IEC 61400-11 AMD 2018: ed. 3.1. The narrowband analysis of the wind turbine tonal noise component is fully evaluated as given in the standard. The identification of tone and classification of spectral lines is performed for all spectra of the specified wind speed bin. The results are obtained based on the IEC approach: masking level, tonality, and tonal audibility for the sample data of a specific wind speed bin. The audible tones are found for all spectra and reported in the results. The IEC method gives a good prospect of tonality assessment for wind turbine noise measurement from this result.

The Use of Cannabis Derived Medical Products in the Treatment of Children’s Cancer: A Systematic Review
Authors: Gajic Nikolai , Murphy Cait , Ritchie Sarah , Saunders Charlie , Murphy Dermot
Published: September 2022

Legislative change to cannabis use has generated significant interest
into the therapeutic utility of cannabis-derived medical products,
particularly in the field of oncology. However, much of this research
has focused on adults, leaving physicians and caregivers uncertain as to
the safety and efficacy of cannabinoids amongst the pediatric
demographic. To this end, the aim of this review is to examine the scope
of pharmaceutical cannabis in treatment of pediatric cancer, evaluating
its utility as an anti-cancer therapeutic as well as symptom relief
agent. This systematic review was conducted following the PRISMA
guidelines. 30 included articles comprised of 16 clinical and 14
preclinical studies. There is reasonable evidence to support the use of
cannabis in CINV, with plausible utility for other facets of symptomatic
relief. Preclinical pediatric cancer models, investigating anti-cancer
cannabinoid effect, have provided evidence that may warrant first phase
clinical trials.
Intersecting effects of landscape and body size on dispersal in bee populations
Authors: Hernandez Melissa , Suni Sevan S.
Published: September 2022

Quantifying genetic structure and levels of genetic variation are
fundamentally important to predicting the ability of populations to
persist in human-altered landscapes and adapt to future environmental
changes. Genetic structure reflects the dispersal of individuals over
generations, which can be mediated by species-level traits or
environmental factors. Dispersal distances are commonly positively
associated with body size and negatively associated with the amount of
degraded habitat between sites, motivating investigation of these
potential drivers of dispersal concomitantly. We quantified genetic
structure and genetic variability within populations of ten bee species
in the tribe Euglossini across fragmented landscapes. We genotyped bees
at thousands of SNP loci and tested the following predictions: (1)
larger species disperse farther; (2) species with greater resource
specialization disperse farther; (3) deforested areas restrict
dispersal; and (4) sites surrounded by more intact habitat have higher
genetic diversity. Body size was a strong predictor of genetic
structure, but, surprisingly, larger species showed higher genetic
structure than smaller species. The way that deforestation affected
dispersal varied with body size, such that larger species dispersed less
far in areas with more forest. There was no effect of geographic
distance on dispersal, and sites with more intact habitat had higher
genetic diversity. These results challenge the dominant paradigm that
individuals of larger species disperse farther, motivating further work
into ecological drivers of dispersal for bees.

Published: September 2022

The eastern tree hyrax is thought to be a solitarily living arboreal
species of the forests of East Africa. However, in the coast of Kenya,
indigenous forests have been almost entirely cleared, and some of the
last tree hyrax populations live in limestone rocky formations and
caves. Interestingly, they seem to be living in social groups. Here, we
describe and document photographically these unique tree hyrax
populations. We also describe their acoustical communication and their
calling activity in three different habitats. Based on these animals’
physical appearance and acoustic analyses of their calls, they represent
the species eastern tree hyrax, Dendrohyrax validus. Due to immence
pressure from humans, the future of these small and isolated,
cave-living tree hyrax populations does not seem bright.
