Primates occur in 90 countries, but four—Brazil, Madagascar, Indonesia, and the Democratic Republic of Congo (DRC)—harbor 65% world’s primate species (439) 60% these primates are Threatened, Endangered, or Critically Endangered (IUCN Red List Threatened Species 2017-3). Considering their importance for global conservation, we examine anthropogenic pressures each country is facing that place populations at risk. Habitat loss fragmentation main threats to Brazil, Indonesia. However, DRC...

Abstract Threats to biodiversity are well documented. However, effectively conserve species and their habitats, we need know which conservation interventions do (or not) work. Evidence-based evaluates within a scientific framework. The Conservation Evidence project has summarized thousands of studies testing compiled these as synopses for various habitats taxa. In the present article, analyzed assessed in primate synopsis compared with other We found that despite intensive efforts study...

Some conservation prioritization methods are based on the assumption that needs overwhelm current resources and not all species can be conserved; therefore, a triage scheme (i.e., when system is overwhelmed, should divided into three groups likelihood of survival, efforts focused those in group with best survival prospects reduced or denied to no needing special for their conservation) necessary guide resource allocation. We argue this decision-making strategy appropriate because as limited...

Few Malagasy children and adults are aware of the rare unique fauna flora indigenous to their island-continent, including flagship lemur species. Even ancestral proverbs never mentioned lemurs, but these same talked about now extinct hippopotamus. Madagascar's geography, history, economic constraints contribute severe biodiversity loss. Deforestation on Madagascar is reported be over 100,000 ha/year, with only 10-15% island retaining natural forest [Green & Sussman, 1990]. Educating...

Abstract Camera traps are standard tools for assessing populations of medium–large terrestrial mammals, particularly rare, elusive or cryptic species, yet few researchers have attempted to employ camera document rare primates in arboreal settings. We examined different camera-trap techniques the Critically Endangered greater bamboo lemur Prolemur simus Madagascar. documented P. at two sites, confirming presence one site. Most including 86% all occurrences, were low light conditions (c. <...

Abstract Management and monitoring of community-based protected areas in Madagascar remain challenging because a lack financial, human technical resources, capacity. At Lake Alaotra, conversion marshland for rice cultivation effective habitat protection have pushed the locally endemic Alaotra gentle lemur Hapalemur alaotrensis to brink extinction. The highest density species is found managed Park Bandro, high-priority conservation zone within New Protected Area. We evaluated local awareness...

The growing concern for the ongoing biodiversity loss drives researchers towards practical and large-scale automated systems to monitor wild animal populations. Primates, with most species threatened by extinction, face substantial risks. We focused on vocal activity of indri (Indri indri) recorded in Maromizaha Forest (Madagascar) from 2019 2021 via passive acoustics, a method increasingly used monitoring activities different environments. first indris’ songs, loud distinctive sequences,...

Abstract Corruption affects biodiversity conservation. Mechanisms that more effectively reform corruption and mitigate negative effects of on conservation are needed, especially in hotspots such as Madagascar. Local definitions corrupt behavior, attitudes about reforms, motivations for noncompliance may generate deeper understanding corruption, which turn advance the community's thinking invite new solutions. We conducted in‐depth interviews with Malagasy residents living adjacent to...

Among mammals, the order Primates is exceptional in having a high taxonomic richness which taxa are arboreal, semiterrestrial, or terrestrial. Although habitual terrestriality pervasive among apes and African Asian monkeys (catarrhines), it largely absent of Americas (platyrrhines), as well galagos, lemurs, lorises (strepsirrhines), mostly arboreal. Numerous ecological drivers species-specific factors suggested to set conditions for an evolutionary shift from arboreality terrestriality,...
