Comment on "Habitat split and the global decline of amphibians".
نویسنده
چکیده
Becker et al. (Reports, 14 December 2007, p. 1775) reported that forest amphibians with terrestrial development are less susceptible to the effects of habitat degradation than those with aquatic larvae. However, analysis with more appropriate statistical methods suggests there is no evidence for a difference between aquatic-reproducing and terrestrial-reproducing species.

Habitat split and the global decline of amphibians.
The worldwide decline in amphibians has been attributed to several causes, especially habitat loss and disease. We identified a further factor, namely "habitat split"-defined as human-induced disconnection between habitats used by different life history stages of a species-which forces forest-associated amphibians with aquatic larvae to make risky breeding migrations between suitable aquatic an...
متن کاملDynamics of habitat changes as a result of climate change in Zagros Mountains Range (Iran), a case study on Amphibians
Climate change is currently considered a serious threat for many species and recognized as one of the most important factors in the global biodiversity loss. Among animal groups, amphibians are known to be among the most sensitive groups of vertebrates to climate change due to their inability to travel long distances, and mountain habitat species are more exposed to climate change pressures tha...

The commentator suggests that it is necessary to extend the classical connotation of global city which focuses much on the functions of controlling global capital and production. Global city should also include the dimensions of the leading role and capacity on health improvements and well-being promotion.

متن کاملModeling Habitat Split: Landscape and Life History Traits Determine Amphibian Extinction Thresholds
Habitat split is a major force behind the worldwide decline of amphibian populations, causing community change in richness and species composition. In fragmented landscapes, natural remnants, the terrestrial habitat of the adults, are frequently separated from streams, the aquatic habitat of the larvae. An important question is how this landscape configuration affects population levels and if i...
متن کاملResponse to Comment on “Habitat Split and the Global Decline of Amphibians”
Becker et al. (1) showed a strong effect of habitat split on the richness of species with aquatic larvae but no effect on the richness of species with terrestrial development, both when habitat split was analyzed alone in linear regressions and when it was analyzed together with habitat loss and fragmentation in more complex path analyses. Cannatella (2) argues that if species with aquatic larv...
