What is a home range?
‘‘Home range’’ is a standard concept in animal ecology and behavior but few people try to understand what home ranges mean to the animals that have them and often assume that a home-range estimate, quantified using some method, is the home range. This leads to 2 problems. First, researchers put much energy into discerning and using the ‘‘best’’ methods for estimating home ranges while no one un...
متن کاملHome ranges, habitat and body mass: simple correlates of home range size in ungulates.
The spatial scale of animal space use, e.g. measured as individual home range size, is a key trait with important implications for ecological and evolutionary processes as well as management and conservation of populations and ecosystems. Explaining variation in home range size has therefore received great attention in ecological research. However, few studies have examined multiple hypotheses ...
متن کاملIs online exercise at home more effective than hydrotherapy and physiotherapy in patients with non-specific chronic low back pain? A randomized clinical trial
Abstract Purpose: Many non-pharmaceutical methods have been proposed for the treatment of non-specific chronic low back pain (NCLBP), including Online Exercise at Home (OEH), Hydrotherapy, and Physiotherapy approaches that have shown significant effects. Nevertheless, there are ambiguities in choosing the best option. Therefore, the present study was designed to compare these methods. Methods...
متن کاملHome Range Analysis Using a Mechanistic Home Range Model
The traditional models used to characterize animal home ranges have no mechanistic basis underlying their descriptions of space use, and as a result, the analysis of animal home ranges has primarily been a descriptive endeavor. In this paper, we characterize coyote (Canis latrans) home range patterns using partial differential equations for expected space use that are formally derived from unde...
متن کاملForaging optimally for home ranges
Economic models predict behavior of animals based on the presumption that natural selection has shaped behaviors important to an animal’s fitness to maximize benefits over costs. Economic analyses have shown that territories of animals are structured by trade-offs between benefits gained from resources and costs of defending them. Intuitively, home ranges should be similarly structured, but tra...
