Phylogenetic analysis of mtDNA sequence data confirms the observation that species diversity in world's smallest living primate (genus Microcebus ) has been greatly underestimated. The description three new to science, and resurrection two others from synonymy, justified on morphological grounds is supported by evidence reproductive isolation sympatry. This taxonomic revision doubles number recognized mouse lemur species. molecular phylogenetic analyses presented here verify add a historical...

Abstract Behavioral monitoring is the scientific collection of animal behavior data to understand normal patterns and changes in these patterns. This tool underutilized zoo industry although it can be an effective indicator many potential problems that compromise well‐being. We suggest a behavioral program should core component zoological institution's care program. detail benefits such describe its components. provide guidelines for implementing make recommendations will help institutions...

ABSTRACT Tropical habitats in South America and Africa are being transformed by artisanal gold mining, but few studies have addressed how mining impacts animals at the community level. We assessed long‐term ecological resilience to disturbance for seven primate species ( Allouatta macconnelli , Ateles paniscus Cebus olivaceus Chiropotes sagulatus Pithecia pithecia Saguinus midas Sapajus apella ) Brownsberg Nature Park, Suriname over a 20‐year period. Using 11 trails unpaved roads calculate...

This commentary emerged from a panel presentation at the International Primatological Society Congress in Nairobi, Kenya, 2018. The goal was to provide regional updates on status of primate removal habitat countries, especially for pet trade, and develop guidelines that could help primatologists address this critical problem. trade live primates includes those used as pets, entertainment, subjects biomedical experimentation, but here we focus destined trade. Such transactions are hugely...

Through a 16-mo mark–recapture trap study, I examined aspects of spatial distribution and population composition in the brown mouse lemur, Microcebus rufus, 42 g nocturnal strepsirhine. The study took place rainforest Ranomafana National Park southeastern Madagascar. Sherman live traps were set monthly for variable number nights quasi-grid 50 m apart. Captured individuals marked future identification released at site capture. More males than females captured overall (102 versus 72) 83%...

Highlights By providing mentorship and by enhancing professional development skills, primatologists can help to build the capacity of emerging conservationists. Actions be adjusted specific cultural contexts interwoven into teaching research programs. Sharing stories about pivotal career moments creates closer connections with mentees helps stimulate dialogue on issues concern. Experiential networking opportunities assist broaden perspectives students young professionals poised for...

Abstract To evaluate whether observed cycles in proceptive behavior aging lowland gorilla females (age 40+) at Brookfield Zoo were driven by ovarian activity, we compared monthly behavioral data to estradiol and progestogen based on fecal hormone assessments. Progestogen peaks showed regularity close coincidence with sexual behaviors. Estradiol was more variable. varied between 22±5 days for the control female (29 years old), 24±2.5 29±8 two aged subjects. In first female, which housed other...

As our closest living relatives, great apes likely experience physiological patterns associated with reproductive aging that are similar to humans. We present results from a nationwide zoo-based study on female western lowland gorillas during which we evaluated concentrations of progestogens via daily fecal sampling in 30 gorillas, 22 whom were geriatric (≥30). Whereas control females cycled regularly, ca. 23% acyclic (menopausal), and approximately 1/3 showed variable hormonal suggestive...

The population of western lowland gorillas in North American zoos is aging and, as the case with human population, may have unique physical and social needs. We documented previously that 25% females (5/22) ceased to show reproductive cycles entirely, could be defined menopausal. Approximately 32% showed somewhat irregular cycling patterns. review our hormonal behavioral findings on gorillas; describe range patterns we see how interpret these; discuss implications these for captive...

Abstract Combination birth control pills (CBC) are one of the most common methods used for western lowland gorillas ( Gorilla gorilla ) housed in zoos. Since zoos interested maintaining as many natural behaviors possible, it is important to know how contraception may affect social and sexual interactions among group members. Although some data available regarding influence pill on behavior human females, no its effects estrous behavior. We examined temporal trends estrous, aggressive,...

Abstract International laws and conventions have gone a long way in reducing the number of wild primates entering United States America (US) for pet trade. However, breeding sale to private owners continues, individual states present bewildering array regulations on holding as pets. As primatologists we can act decrease demand primate pets by (1) speaking out inappropriate use mass media especially social media; (2) not posing photographs close proximity primates; (3) continuing educate...

The enormous destruction of natural habitats in Madagascar by humans forces us to initiate programmes for the conservation its endangered species, such as lemurs. At present, our knowledge population biology these species is rather limited and this study has, therefore, been undertaken learn more about genetics In past, has influenced mainly ecology, but necessity genetic approaches widely recognized during last 15 years [1–5]. structure populations, e.g. amount variability, degree diversity...

This paper explores age-related post-mortem changes in zoo-housed gorillas. Our previous research examined hormonal ageing western lowland gorilla ( Gorilla ) females order to assess whether they experienced menopause. We had the opportunity investigate these showed similar those seen human females, and or not are associated with general patterns of ageing, hormone-mediated changes, both. reviewed necropsy reports for 14 ranging age from 30 56 years at time death. evaluated all...
