Understanding the perceptual world of horses
From the viewpoint of experimental psychology, there are two problems with our current knowledge of equine perception. The first is that the behavioral and neurophysiological research in this area has enormous gaps, reflecting that this animal is not a co

Wildlife encounters by Lewis and Clark: A spatial analysis of interactions between native Americans and wildlife
The Lewis and Clark journals contain some of the earliest and most detailed written descriptions of a large part of the United States before Euro-American settlement. We used the journal entries to assess the influence of humans on wildlife distribution a

Social and sexual behaviour of horses under semi-natural and stable conditions in relation to their reproductive efficiency: A review.
In mares kept under stable conditions, oestrus detection is mainly based on mare’s behaviour towards a teaser stallion. Weak or equivocal signs of oestrus in mares may be one of the reasons of decreasing reproduction indices in horses in recent years in Poland. Social aspects of horses’ sexual behaviour under natural conditions and the impact [...]

Researching feral horse ecology and behavior: Turning political debate into opportunity
Funding for biological research on feral horse populations is often motivated by political debate. Thus, research may start too late to contribute substantially to decisions about population monitoring and management, or to resolve public debate. Feral ho

Preliminary study of the development of the flehmen response in Equus caballus
The flehmen response is commonly seen in most ungulates as well as in several other species (e.g. felids). The behavior is most often thought to be part of the sexual behavioral repertoire of males. One reigning hypothesis suggests that this behavior allo

No other animal had influenced the economic and cultural history of men in such extend. Hunting prey since the icetimes, domesticated 4000 B.C. and used for thousands of years as unique animal all over the world [...]

Grazing patterns of Pantaneiro horses. An element of adaptability to the Pantanal region, Brazil
Seasonal foods and habitat use of Pantaneiro horses were determined in two Pantanal subregions: Nhecolandia (March 1990 to February 1991) and Abobral (December 1993 to October 1995). In both sub-regions, a direct pasture observation method was used in two daily sessions (morning and afternoon). The forage plants eaten and habitat occupied by animals were recorded [...]

Genetics and behaviour in horses.
The genetics of behaviour in horses is just starting. The interest of including behavioural traits in selection has been only recently underlined. Moreover, it is a difficult question to tackle in horses as animals are dispersed in a variety of environmen
