The conservation status of birds in the Ketambe Research Station area, Gunung Leuser National Park, needs to be done so that more attention can paid preservation bird diversity. This study aims observe various three altitude zones, namely zone 1 (350-550 m asl), 2 (550-800 and 3 (800-1050 asl). Observations were made May-August 2019 at Station, Southeast Aceh. results observations as a whole, t...

Reproductive failure is ubiquitous. However, research on the mechanisms underpinning reproductive still lacking in most species. This gap our understanding has particularly strong repercussions for threatened species and it hinders ability to establish effective interventions improve survival. In this review, we focus why eggs fail hatch – one of critical understudied aspects bird reproduction....

In this global extinction crisis, we must act urgently to prevent the loss of species. The public plays a key role in ensuring future our biodiversity, by impacting funding decisions, creating behaviour change, and pushing change corporations species loss.

Asiatic Houbara ( Chlamydotis macqueenii ) is a flagship and vulnerable species. In-situ conservation of this threatened species demands for knowledge of its habitat selection. The aim of this study was to determine habitat variables influencing birds wintering and breeding selection in semiarid central Iran. Habitat features of the detected nest and pellet sites were compared with paired and r...

We present two statistical models documenting variations in density indices of stoats and of mice in New Zealand southern beech (Nothofagus spp.) forests. They confirm previous, simpler correlations showing that the summer capture rate of stoats increases with spring mouse density index up to about 20–25 mouse captures per 100 trap-nights (C/100TN). However, at much higher mouse densities (60–8...

Fast environmental variations due to climate change can cause mass decline or even extinctions of species, having a dramatic impact on the future of biodiversity. During the last decade, different approaches have been proposed to track and monitor endangered species, generally based on costly semi-automatic systems that require human supervision adding limitations in coverage and time. However,...

Africa contains about one-fifth of all known species of plants, mammals, and birds, as well as one-sixth of amphibians and reptiles. These species compose some of the world’s most diverse and biologically important ecosystems such as savannahs, tropical forests, coral reef marine and freshwater habitats, wetlands and montane ecosystems. These globally important ecosystems provide the economic f...
