Abstract Conservation funding is currently limited; cost‐effective conservation solutions are essential. We suggest that the thousands of field stations worldwide can play key roles at frontline biodiversity and have high intrinsic value. assessed stations’ return on investment explored impact COVID‐19. surveyed leaders across tropical regions host primate research; 157 in 56 countries responded. Respondents reported improved habitat quality reduced hunting rates over 80% lower operational...

Abstract We studied an adult female and a juvenile male aye-aye ( Daubentonia madagascariensis ) in Madagascar’s Ihofa forest from May to December 2017 investigate whether the postural diversity of this lemur varied with age, maintenance activity, habitat use. used bout sampling (female N = 488, 355) record postures during feeding resting tested for differences using . For both individuals, bimanual unimanual cling were most common (78.4% 82.9%) these behaviors strongly associated use...

Abstract The degree of dietary flexibility in primates is species specific; some incorporate a wider array resources than others. Extreme interannual weather variability Madagascar results seasonal resource scarcity which has been linked to specialized behaviors lemurs. Prolemur simus , for example, considered an obligate specialist on large culm bamboo with >60% its diet composed woody bamboos requiring morphological and physiological adaptations process. Recent studies reported...

Previous studies found that aye-ayes ( Daubentonia madagascariensis ) consume a variety of non-invertebrate resources, supporting the hypothesis are too large-bodied to focus feeding efforts on insects. However, these conclusions were based introduced populations, with little known about aye-aye behaviour and ecology in its natural habitat. This study investigates activity budgets, diet, home range/territories 2 male Kianjavato Classified Forest, disturbed forest south-eastern Madagascar,...

The aye-aye is considered the most widely distributed lemur in Madagascar; however, effect of forest quality on abundance unknown. We compared presence across degraded and non-degraded at Ranomafana National Park, Madagascar. used secondary signs (feeding sites, high activity sites) as indirect cues Canarium trees an indicator resource availability. All 3 measured variables indicated higher within forest; differences type were not significant. Both forests showed a positive correlation...

In this research, we focused on aye-aye populations in Ranomafana National Park, Madagascar. From August to December 2008, tested how feeding was influenced by presence/absence of both fruiting and non-fruiting Canarium trees. Deadwood traces were used as a proxy for evidence feeding. We enumerated deadwood 20 locations, 10 with Canarium, without. Each location contained two transects (80 m L × W) total area 5.6 ha. Feeding trace results locations compared non- not significant (Z = –1.926, p...

Madagascar’s dramatic climatic fluctuations mean most lemurs adjust behaviors seasonally as resource availability fluctuates. Many will adopt one of two strategies, a maximizer or an area minimizer, when adjusting to seasonal shifts in availability. However, it is unknown if and how aye-aye ( Daubentonia madagascariensis ) ranging behavior influenced by seasonality. We explored whether habitat use changed seasonally. followed aye-ayes, adult male female, the undisturbed forest Torotorofotsy,...

Abstract Objectives Jarman/Bell principle and Kay's threshold suggest that large animals should not be able to sustain themselves on insects. However, with specialized morphological and/or behavioral adaptations violate these assumptions. Male aye‐ayes were recently identified as having an insectivorous diet despite weighing 2.5 kg. We further explored this diet/body size disparity by studying behaviors of adult female juvenile male aye‐aye. Materials Methods collected data aye‐aye in...

Abstract The role of folivorous primates in ecosystem restoration has been largely overlooked. This may primarily be due to the lack basic ecological information on many these species. northern sportive lemur ( Lepilemur septentrionalis ), for example, is one most endangered world, yet we baseline knowledge this lemur. dearth only serves exacerbate their situation as conservation initiatives do not have fundamental needed properly manage efforts To obtain an L. , used instantaneous focal...

Abstract Aye‐ayes ( Daubentonia madagascariensis ) locate and acquire invertebrates from within woody substrates at all levels of the rainforest; yet how their locomotion helps them accommodate this diet has not been explored in detail. We studied locomotor behavior an adult female N = 1,085) juvenile male 708) aye‐aye undisturbed forest Torotorofotsy, Madagascar May to December 2017. used bout sampling record during foraging travel two radio‐collared individuals. χ 2 tests compare overall...

Infanticide occurs in an array of mammalian species, especially primates. Most infanticidal events occur polygynous societies, though they sometimes happen nongregarious populations. We witnessed a possible event 3-month-old male aye-aye, species that exhibits dispersed multimale social system, Torotorofotsy, Madagascar. Though firsthand killing the infant was not observed, physical injuries to infant, vocalizations adult female, and her subsequent chase aye-aye strongly indicates...

Abstract Anthropogenic activities are negatively affecting the flora and fauna of Madagascar, including its Endangered flagship lemur species, ring-tailed Lemur catta . Population numbers at some sites rapidly declining, yet much species' habitat is insufficiently surveyed. Because widespread population assessments critical to guiding conservation management strategies, additional data needed monitor L. trends identify limits their geographical range. Here we report survey results confirming...

Abstract.—Effective management strategies for at-risk chelonian populations require sound knowledge of populationdemographics. Previous research on the Critically Endangered Radiated Tortoise, Astrochelys radiata (Shaw 1802),revealed a trend increasing male bias in sex ratio and concomitant decrease proportion juveniles inLavavolo, southern Madagascar. This location is one few remaining sites with high concentration this speciesand was last studied ten years ago. The aim our study to provide...
