Wildlife and Species Interactions
Human Persecution is An Important Threat to the Conservation of the Endangered Black-and-Chestnut Eagle in Northern AndesBackgroundHuman-wildlife conflicts are widespread and put threatened species at an even higher risk of extinction. Human persecution of threatened wild animals with the aim to protect domesticated animals contributes to the decline of threatened wild animals. The black-and-chestnut eagle is under threat in the northern Andes of Ecuador and Colombia due to efforts to protect domestic poultry. Open access copy available |
Lightly-harvested rustic cocoa is a valuable land cover for amphibian and reptile conservation in human-modified rainforest landscapesBackgroundTropical biodiversity is impacted by anthropogenic land covers such as agriculture. Land use has the ability to both negatively and positively impact tropical biodiversity. In the tropics, important crops are grown in tropical forested landscapes such as coffee and cocoa. These forest understories are also important habitats for highly sensitive and ecologically vulnerable amphibian species. Amphibians and reptiles are an understudied taxa in conservation ecology and targeted in this study. Open access copy available |
National parks and conservation concessions: a comparison between mammal populations in two types of tropical protected areas in Ucayali, PeruBackgroundPeru holds the second largest portion of the Amazon rainforest and is threatened by illegal logging and crop cultivation, as well as mining and other activities. Protected areas are one method of forest conservation, which can exist as conservation concessions. These areas of land granted for protection and rehabilitation area vital to maintaining the health and distribution of the forest. Biodiversity is understudied in many of these regions, especially about terrestrial mammals. Open access copy available |
Seed removal, seed dispersers, and the allocation of tissues in Myrtaceae seedsBackgroundPlants allocate resources to protective seed tissues in order to avoid seed death and ensure successful reproduction. Myrtaceae is an abundant plant family in the Brazilian Atlantic forest with many species producing fleshy fruits that are attractive to birds, rodents, and other mammals. Myrtaceae species may adapt seed characteristics to avoid predation. Available with subscription or purchase |
Safeguarding sloths and anteaters in the future: Priority areas for conservation under climate changeBackgroundSloths and anteaters come from the order Pilosa which has very little species richness and a high rate of species loss in recent years, making this order highly vulnerable to extinction. This order is distributed endemically in the Neotropics. Conservation concerns are high due to the high levels of habitat fragmentation and loss in Neotropical landscapes and conservation areas need to be prioritized to ensure Pilosa species survival.

Forest structure predicts species richness and functional diversity in Amazonian mixed-species bird flocksBackgroundSecondary forests between forest fragments are valuable sources of biodiversity during the regeneration process. In the Brazilian Amazon, understory birds are often an indicator of forest regeneration and overall health. Functional diversity is an important component of ecosystem health and services, yet little is known about the role it plays in the return of mixed-species bird flocks. Open access copy available |
Spatial density patterns of herbivore response to seasonal dynamics in the tropical deciduous forest of central IndiaBackgroundStrong seasonality of dry tropical forests causes variations in vegetation and therefore food resources for animals. This study investigates the seasonal distribution patterns between summer and winter of four ungulate species (Rusa unicolor, Axis axis, Bocephalus tragocamelus, and Sus scrofa) in the Panna Tiger Reserve in India. Ungulates tend to gravitate towards areas that are cooler with more vegetation, and at higher elevations. Available with subscription or purchase |
Effects of plant species richness on the structure of plant-bird interaction networks along a 3000-m elevational gradient in subtropical forestsBackgroundThe structure and diversity of ecological communities is shaped by symbiotic plant and animal relationships. Some birds feed on fleshy fruit producing plants to disperse seeds and facilitate plant reproduction. Bird seed-dispersal networks are plant-animal assemblages that change with environmental conditions. Species richness and species specialization interact with elevation to result in unique assemblages. In this study, the authors examine how plant and bird interactions change with plant species richness along a 3000-meter gradient in a subtropical forest in China.

Multiple invasions exert combined magnified effects on native plants, soil nutrients and alters the plant-herbivore interaction in dry tropical forestBackgroundGlobalization has resulted in a higher number of species invasions, which have had detrimental impacts on ecosystem biodiversity, functions, and services. Assessment and management of all invasive species is based on knowledge of a small number of species. Management is also focused on single-species invasions rather than multiple simultaneous invasions. India has a high level of species invasions and minimal resources to control them.

Designing optimal human-modified landscapes for forest biodiversity conservationIntroductionCurrent land-use patterns have resulted in the rapid conversion of forests to human modified forest landscapes (HMFLs). This degradation of forest landscapes can threaten species diversity and disrupt the ecological functions and services they provide. As such, designing and implementing effective landscape conservation strategies that benefit biodiversity as well as promote human well-being is essential. Open access copy available |
