Home Range
A home range is the area in which an animal lives and moves on a periodic basis. It is related to the concept of an animal's territory which is the area that is actively defended. The concept of a home range was introduced by W. H. Burt in 1943. He drew maps showing where the animal had been observed at different times. An associated concept is the utilization distribution which examines where the animal is likely to be at any given time. Data for mapping a home range used to be gathered by careful observation, but nowadays, the animal is fitted with a transmission collar or similar GPS device. The simplest way of measuring the home range is to construct the smallest possible convex polygon around the data but this tends to overestimate the range. The best known methods for constructing utilization distributions are the so-called bivariate Gaussian or normal distribution kernel density methods. More recently, nonparametric methods such as the Burgman and Fox's alpha-hull and Getz a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convex Polygon
In geometry, a convex polygon is a polygon that is the boundary of a convex set. This means that the line segment between two points of the polygon is contained in the union of the interior and the boundary of the polygon. In particular, it is a simple polygon (not self-intersecting). Equivalently, a polygon is convex if every line that does not contain any edge intersects the polygon in at most two points. A strictly convex polygon is a convex polygon such that no line contains two of its edges. In a convex polygon, all interior angles are less than or equal to 180 degrees, while in a strictly convex polygon all interior angles are strictly less than 180 degrees. Properties The following properties of a simple polygon are all equivalent to convexity: *Every internal angle is strictly less than 180 degrees. *Every point on every line segment between two points inside or on the boundary of the polygon remains inside or on the boundary. *The polygon is entirely contained in ...

Dear Enemy Recognition
The dear enemy effect or dear enemy recognition is an ethological phenomenon in which two neighbouring territorial animals become less aggressive toward one another once territorial borders are well established. As territory owners become accustomed to their neighbours, they expend less time and energy on defensive behaviors directed toward one another. However, aggression toward unfamiliar neighbours remains the same. Some authors have suggested the dear enemy effect is territory residents displaying lower levels of aggression toward familiar neighbours compared to unfamiliar individuals who are non-territorial "floaters".Bee, M.A., (2003). A test of the "dear enemy effect" in the strawberry dart-poison frog (''Dendrobates pumilio''). Behavioral Ecology and Sociobiology, 54: 601-610 The dear enemy effect has been observed in a wide range of animals including mammals, birds, reptiles, amphibians, fish and invertebrates. It can be modulated by factors such as the location of the fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indigenous peoples in Canada, Indigenous peoples have inhabited what is now Manitoba for thousands of years. In the early 17th century, British and French North American fur trade, fur traders began arriving in the area and establishing settlements. The Kingdom of England secured control of the region in 1673 and created a territory named Rupert's Land, which was placed under the administration of the Hudson's Bay Company. Rupe ...

JMIR
The ''Journal of Medical Internet Research'' is a peer-reviewed open-access medical journal established in 1999 covering eHealth and "healthcare in the Internet age". The editors-in-chief are Gunther Eysenbach and Rita Kukafka. The publisher is JMIR Publications. Publisher The journal is published by JMIR Publications, which was a cofounder of the Open Access Scholarly Publishers Association and is known for other journal titles as well, which mostly focus on specific subtopics within eHealth, such as mHealth (JMIR mHealth and uHealth), serious games (JMIR Serious Games), mental health (JMIR Mental Health), and cancer (JMIR Cancer). JMIR Publications is also notable for being one of the fastest-growing companies in Canada in 2019 . Controversy JMIR Publications has faced criticism for initially using the same editorial board of its main journal for its sister journals and for offering a fast-track review pathway for a surcharge.
