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...
Animal communication has long been thought to be subject pressures and constraints associated with social relationships. However, our understanding of how the nature quality relationships relates use evolution is limited by a lack directly comparable methods across multiple levels analysis. Here, we analysed observational data from 111 wild groups belonging 26 non-human primate species, test vocal dominance style (the strictness which hierarchy enforced, ranging ‘despotic’ ‘tolerant’). At...
Abstract Social behavior is a key adaptation for group‐living primates. It important to assess changes social in human‐impacted landscape zones better understand the impact of anthropogenic disturbance on primate species. We investigated rate and type three species platyrrhines across 100 m edge interior fragmented forest Costa Rica, La Suerte Biological Research Station (LSBRS). Following results from other sites, we predicted that spider monkeys ( Ateles geoffroyi ), capuchin Cebus...
Abstract Rivers represent natural edges in forests, serving as transition zones between landscapes. Natural edge effects are important to study understand how intrinsic habitat variations affect wildlife well the impact of human‐induced forest fragmentation. We examined influence riparian and anthropogenic on mantled howler, white‐faced capuchin, Central American spider monkeys, vegetation structure at La Suerte Biological Research Station (abbreviated LSBRS), Costa Rica. predicted lower...
The ring-tailed lemur (Lemur catta) is a group-living strepsirrhine primate endemic to Madagascar that faces considerable predation pressure from aerial and terrestrial predators. This species engages in mobbing vigilance behavior response predators, has referential alarm vocalizations. Because L. catta female dominant, less known about the calls of males. We tested 3 hypotheses for male antipredator vocalization on at Bezà Mahafaly Special Reserve Madagascar: predator confusion, group...
Abstract The function of long calling is a subject interest across animal behaviour study, particularly within primatology. Many primate species have male‐specific long‐distance calls, including platyrrhines like the folivorous howler monkey ( Alouatta spp.). Howler monkeys may howl to defend resources such as feeding trees or areas rich vegetation from other groups. This study tests ecological resource defence hypothesis for howling in mantled palliata ) and investigates how anthropogenic...
Forest fragmentation increases forest edge relative to interior, with lower vegetation quality common for primates in zones. Because most live human-modified tropical forests within 1 km of their edges, it is critical understand how cope effects. Few studies have investigated inhabiting a fragment alter behaviour across and interior Here we investigate anthropogenic edges affect the activity spatial cohesion mantled howler monkeys ( Alouatta palliata ) at La Suerte Biological Research...
Abstract The ways that forest edges may affect animal vocalization behaviour are poorly understood. We investigated the effects of various types edge habitat on loud calls (howls) a folivorous-frugivorous primate species, Alouatta palliata , with reference to ecological resource defence hypothesis, which predicts males howl defend vegetation resources. tested this hypothesis across four zones — interior, riparian, anthropogenic, and combined in riparian fragment Costa Rica. predicted howling...
Abstract Squeals are sharp and forceful short‐range vocalizations used as aggressive submissive agonistic signals by many mammalian species. The ring‐tailed lemur ( Lemur catta ), a female‐dominant strepsirhine primate, has male‐specific squeal call with proposed male–male functions male–female courtship that have never been empirically tested. goal of my study is to clarify why males at other females applying the handicap hypothesis this vocalization. This rarely tested in primates,...
Abstract Rivers are important components of animal habitats worldwide. The area near riparian edge (⩽100 m from the river) has different abiotic characteristics and vegetation than both forest interior areas bordering human development, which may lead to differences in feeding behaviour. To better contextualize impact human-caused habitat destruction on ecology, it is study natural anthropogenic edges within same habitat. We compared howler monkey ( Alouatta palliata ) behaviour tree use...
Maderas Rainforest Conservancy (MRC) was incorporated as a conservation nonprofit organization in 2008, and manages two sites where biological field courses have been offered since the 1990s: La Suerte Biological Research Station Costa Rica, Ometepe Nicaragua. MRC employs One Health approach to education, can serve model for other sites. The Nicaraguan Molina family, who owns sites, partnered with primatologist Paul Garber 1994 develop primate course aimed at introducing university students...
Maderas Rainforest Conservancy (MRC) is a conservation-focused non-profit organization that devoted to protecting the tropical forests they manage in Costa Rica and Nicaragua providing conservation education for international university students through biological field schools.

This involves classroom lectures, training primate identification methods, execution of research...
Abstract The ring‐tailed lemur ( Lemur catta ) is a group‐living strepsirhine primate endemic to Madagascar that has complex vocal repertoire including affiliative moan and hmm calls. Past research suggested both vocalisations may be contact calls, we assessed their usage in addition examining the effect of individual differences social factors on male calling behaviour. We tested three hypotheses: group cohesion, preferred companion hypotheses. From March July 2010, 565 h focal animal data...
Affiliative vocalizations occur across primate taxa and may be used to maintain spatial cohesion and/or regulate social interactions in group-living species. For gregarious strepsirhines like the ring-tailed lemur ( Lemur catta ), with large vocal repertoires several distinct affiliative including chirp wail, it is important understand behavioural usage of these gain insight into their interactions. To determine whether wail facilitate group cohesion, achieve socially positive outcomes, are...
Abstract Objectives Many group‐living primate species have evolved the capacity for some individuals to live alone part of their lives, but this solitary life stage has rarely been subject focused research. The mantled howler monkey ( Alouatta palliata ) is a social with bisexual dispersal that lives in mixed‐sex groups low male‐to‐female sex ratios. Consequently, males often spend long period as individuals. This study compares tree use, feeding, and long‐distance vocalization behavior...
In mammals, purring has been described in mostly affiliative contexts. the ring-tailed lemur (Lemur catta), both males and females purr, but only were observed agonistic order to determine whether male lemurs purr as aggressive displays during intrasexual encounters, 480 h of focal data collected on 25 adult from Beza Mahafaly Special Reserve, Madagascar, March July 2010. The rate increased periods male-male agonism when compared times without agonism, was positively correlated with...
