Understanding the spatial dimensions of hunting and prey population dynamics is important in order to estimate the sustainability of hunting in tropical forests. We investigated how hunting offtake of vertebrates differed in mixed forest and monodominant forest (composed of Gilbertiodendron dewevrei) and over different spatial extents within the hunting catchment around the logging town of Kabo...

Lion populations have undergone a severe decline in West Africa. As baseline for conservation management, we assessed the group structure of lions in the Pendjari Biosphere Reserve in Benin. This reserve, composed of one National Park and two Hunting Zones, is part of the WAP transboundary complex of protected areas. Overall mean group size was 2.6±1.7 individuals (n = 296), it was significantl...

Hunting is one of the human activities that directly affect wildlife and has received increasing attention given its socioeconomic dimensions. Most studies have been conducted on coastal and wetland areas and showed that hunting activity can greatly affect bird behaviour and distribution. Hunting-free reserves for game species are zones where birds find an area of reduced disturbance. We evalua...

We monitored 142 radiocollared adult (!1.0 yr old) white-tailed deer (Odocoileus virginianus) in 3 study areas of Massachusetts, USA, to estimate annual survival and mortality due to legal hunting. We then applied these rates to deer harvest information to estimate deer population trends over time, and compared these to trends derived solely from harvest data estimates. Estimated adult female s...

The island of Tenerife covers 203,000 hectares and has a resident population of 685,582. Approximately 12,500 hunting licenses are issued each year. There are 158,351 hectares currently available for hunting once security zones and protected areas have been excluded, resulting in a theoretical density of nearly 13 hectares per hunter. This excessive pressure has an impact on the following speci...

Work was conducted among traditional, subsistence whale hunters in Lamalera, Indonesia, in order to test if strict biological kinship or lineage membership is more important for explaining the organization of cooperative hunting parties ranging in size from 8 to 14 men. Crew identifications were collected for all 853 hunts that occurred between May 3 and August 5, 1999. Lineage identity and gen...

Most online feedback mechanisms publish unbiased statistics (usually averages) of past ratings. Such mechanisms fail in environments where the same seller sells products of many different qualities, such as marketplaces of used cars and collectibles. This paper presents a novel feedback management mechanism that succeeds in facilitating efficient transactions in such settings. One particularly ...
