Providing a natural diet is key component to improving animal welfare and potentially reducing stereotypic behaviours in captivity. Wild slow lorises (Nycticebus spp.) are threatened by illegal wildlife trade, Thailand, confiscations from trade have led large number of Bengal bengalensis) greater (N. coucang) rescue centers such as Bang Phra Wildlife Domestic Research Station (Bang Phra). Due l...

Being a mosaic of miscellaneous habitats, the Toruń Valley is a refuge for numerous species of animals, who find their shelter here, food and favourable places for reproduction. Countrywide, the Valley is also an important natural ecological corridor for those animals. Regarding this function, the Vistula River is of particular significance within the described area. This study presents species...

Many problems in computational sustainability involve constraints on connectivity. When designing a new wildlife corridor, we need it to be geographically connected. When planning the harvest of a forest, we need new areas to harvest to be connected to areas that have already been harvested so we can access them easily. And when town planning, we need to connect new homes to the existing utilit...

The Ryman-Laikre (R-L) effect is an increase in inbreeding and a reduction in total effective population size (NeT ) in a combined captive-wild system, which arises when a few captive parents produce large numbers of offspring. To facilitate evaluation of the R-L effect for scenarios that are relevant to marine stock enhancement and aquaculture, we extended the original R-L formula to explicitl...

This paper studies the e¤ect of captive consumers in a competitive model of nonlinear pricing. We focus on the bene…ts and drawbacks of allowing what we call market segmentation, namely, a situation where the price-quality menu o¤ered to captive consumers can di¤er from that o¤ered to consumers that are exposed to competition. We …nd that the e¤ect of market segmentation depends on the relation...

This paper empirically examines the current state of the IS offshoring phenomenon in Germany regarding project characteristics and success patterns. Relying on a sample of 304 projects conducted at various industry sectors and companies, results show that IS offshoring primarily occurs in sectors Telecommunications and IT at large corporations. Cost reduction is the main reason for going offsho...

Genetic variability among captive and wild ring-tailed lemurs (Lemur catta) was assessed using mitochondrial and nuclear DNA data. A 529 bp segment of mtDNA was sequenced and 9 microsatellite loci were genotyped for 286 ring-tailed lemurs. Samples were obtained from the well-studied L. catta population at the Bezà Mahafaly Special Reserve and from captive animals at six institutions worldwide. ...

Housing captive primates in environments representative of their wild habitat in many cases can be challenging. Captive white-handed gibbons can be housed in a caged environment or on an island surrounded by a moat. It has been hypothesized that the quality of the captive environment can affect gibbon behavior, as expressed in (or by) their activity budgets. The researcher observed the activity...

Pointing has long been considered to be a uniquely human, universal, and biologically based gesture. However, pointing emerges spontaneously, without explicit training, in captive chimpanzees. Because pointing is commonplace in captive chimpanzees and virtually absent in wild chimpanzees, and because both captive and wild chimpanzees are sampled from the same gene pool, pointing by captive apes...

The success with which animals living in their natural environment nourish themselves must depend upon the exercise of choices in which instinct and appetite play a significant part. When such individuals are transferred to conditions of domestication their freedom of choice, particularly in t’he case of captive or farm animals, is restricted. Their diet now becomes a problem for the husbandman...
