Globally, habitat fragmentation has increased the proximity between wildlife, humans, and emerging predators such as free-ranging dogs. In these fragmented landscapes, encounters between primates and dogs are escalating, with primates often falling victim to dog attacks while navigating patchy landscapes and fragmented forests. We aim to investigate how these primates deal with the simultaneous threats posed by humans and predators, specifically focusing on the adaptive strategies of Central Himalayan langur (CHL) in the landscape of fear.

Article Synopsis
  • Many primate populations are threatened by human activities, but establishing protected areas helps safeguard them, despite ongoing threats like climate change affecting habitat and diseases.
  • A long-term study in Kibale National Park, Uganda, over 52 years involved extensive surveys of five common diurnal primates, revealing generally stable populations, though some fluctuated without clear reasons.
  • Regenerating forests in the park are effectively supporting primate populations, demonstrating the positive impact of conservation efforts by the Uganda Wildlife Authority, despite increasing pressures on the environment.

Terrestrial vertebrates are threatened by anthropogenic activities around the world. The rapid biodiversity loss that ensues is most intense in the tropics and affects ecosystem functions, such as seed dispersal, or may facilitate pathogen transmission. Monitoring vertebrate distributions is essential for understanding changes in biodiversity and ecosystems and also for adaptive management strategies.

Article Synopsis
  • The study focuses on how flies that associate with nonhuman primates are moving between natural habitats and more populated human areas around Kibale National Park in Uganda.
  • Researchers used a mark-recapture method to track the movement of these flies, marking a large number in nine different primate groups and later recapturing some in human-inhabited areas.
  • Genetic analysis showed that these flies carry DNA from various primate parasites, suggesting they could be spreading diseases between nonhuman primates, livestock, and humans in these biodiverse regions.

With open-access publishing authors often pay an article processing charge and subsequently their article is freely available online. These charges are beyond the reach of most African academics. Thus, the trend towards open-access publishing will shift the business model from a pay-wall model, where access to literature is limited, to a pay-to-publish one, where African scholars cannot afford to publish.

Deforestation represents one of the greatest threats to tropical forest mammals, and the situation is greatly exacerbated by bushmeat hunting. To construct informed conservation plans, information must be gathered about responses to habitat degradation, regeneration, and hunting over a sufficiently long period to allow demographic responses. We quantified changes in the abundance of three commonly occurring ungulate species (i.

With 60% of all primate species now threatened with extinction and many species only persisting in small populations in forest fragments, conservation action is urgently needed. But what type of action? Here we argue that restoration of primate habitat will be an essential component of strategies aimed at conserving primates and preventing the extinctions that may occur before the end of the century and propose that primates can act as flagship species for restoration efforts. To do this we gathered a team of academics from around the world with experience in restoration so that we could provide examples of why primate restoration ecology is needed, outline how primates can act as flagship species for restoration efforts of tropical forest, review what little is known about how primate populations respond to restoration efforts, and make specific recommendations of the next steps needed to make restoration of primate populations successful.
