Because of their complex life styles, amphibians and reptiles living in wetlands require both aquatic and terrestrial buffer zones in their protected conservation areas. Due to steep declines in wild populations, the gold-spotted pond frog (Rana chosenica) is listed as vulnerable by the IUCN. However, lack of data about its movements and use of habitat prevents effective conservation planning. ...

Red morwong (Cheilodactylus fuscus; Cheilodactylidae: Perciformes), are large temperate rocky reef ®sh that are patchily distributed in local aggregations of 3 to >100 ®sh. The home ranges and aggregating behaviour of red morwong were investigated using external tags (n ˆ 114, over 35 mo) and ultrasonic transmitters (n ˆ 9 over 20 d) at coastal and estuarine sites in southeast Australia. Adult ...

Quantitative assessments of home-range dynamics and movements of long-tailed weasels (Mustela frenata) are lacking, in spite of the importance of these data to understanding how habitat fragmentation influences behavior, ecology, and interspecific interactions. During autumn to late winter 1998–2000, we monitored 11 long-tailed weasels (7 male, 4 female) via radiotelemetry to examine home-range...

We perform a dynamic general equilibrium analysis of the observed increase in the weight of the average American adult over the 1960-2005 period. Existing evidence suggests that this fifteen pound increase in weight can be attributed to the dramatic raise in the consumption of foods prepared away from home, which resulted in higher caloric intake. We evaluate the impact of the observed trends i...

The views and opinions expressed or implied in this article are those of the author (or authors) and do not necessarily reflect the position of the National Marine Fisheries Service, NOAA. Abstract—Fine-scale movements of and use of habitat space by individual marine fishes can structure broader population dynamics, yet little is known about these traits. This lack of key information applies to...

We investigated effects of roost loss due to clear-fell harvest on bat home range. The study took place in plantation forest, inhabited by the New Zealand long-tailed bat (Chalinolobus tuberculatus), in which trees are harvested between the ages 26-32 years. We determined home ranges by radiotracking different bats in areas that had and had not been recently clear-fell harvested. Home ranges we...

We used radio-telemetry and collar-mounted activity sensors to compare home range size, habitat use, and activity patterns of owned and unowned free-roaming cats on the outskirts of ChampaignUrbana, Illinois, USA. Owned cats (3 M, 8 F) had smaller home ranges than unowned cats (6 M, 10 F), but we failed to detect consistent differences in home range size between the sexes or among seasons. Home...
