Many animal species are detected primarily by sound. Although songs, calls and other sounds are often used for population assessment, as in bird point...

Although research has focused on density-dependent responses of hosts to single-parasite infections, hosts are exposed to numerous parasites simultane...

Pest management is essential to maintain agricultural production, but recent shifts in policies and the development of insecticide resistance have res...

Line transect survey techniques have been used to estimate population density for a variety of mammal species in tropical forests. This paper investig...

Biological control of crop pests is a major ecosystem service affected by several variables acting at multiple spatial scales. Among these variables, ...
