Sorex araneus; body size; coasts; feet; islands; shrews; small mammals; temperature; Scotland
Abstract:
... Island populations of small mammals are often characterized by a larger body size compared with neighbouring mainland or continental populations of the same species. A number of reasons have been put forward to explain this phenomenon. The aim of this study was to test which of these hypotheses can best explain the increase of body size in common shrews (Sorex araneus) on islands. The fieldwork fo ...

Abstract:
... Forest restoration in ponderosa pine and mixed ponderosa pine-Douglas fir forests in the US Rocky Mountains has been highly influenced by a historical model of frequent, low-severity surface fires developed for the ponderosa pine forests of the Southwestern USA. A restoration model, based on this low-severity fire model, focuses on thinning and prescribed burning to restore historical forest struc ...

The assumedly anomalous occurrence of savannas and forest-savanna mosaics in the Gran Sabana - a neotropical region under a climate more suitable for tropical rain forests - has been attributed to a variety of historical, climatic, and anthropogenic factors. This paper describes a previously undocumented shift in vegetation and climate that occurred during the early Holocene, and evaluates its sig ...

Abstract:
... The distinct nature of island populations has traditionally been attributed either to adaptation to particular insular conditions or to random genetic effects. In order to assess the relative importance of these two disparate processes, insular effects were addressed in the European wood mouse, Apodemus sylvaticus (Linnaeus, 1758). Wood mice from 33 localities on both mainland and various Atlantic ...

Abstract:
... Although biogeography and ecology had previously been considered distinct disciplines, this outlook began to change in the early 1990s. Several people expressed interest in creating a link that would help ecologists become more aware of external influences on communities and help biogeographers realize that distribution patterns had their genesis at the community level. They proposed an interdisci ...
