Understanding genetic differentiation and speciation processes in marine species with high dispersal capabilities is challenging. The Chilean dolphin, Cephalorhynchus eutropia, is the only endemic cetacean of Chile and is found in two different coastal habitats: a northern habitat with exposed coastlines, bays and estuaries from Valparaíso (33°02'S) to Chiloé (42°00'S), and a southern habitat w...

Aim To determine the ecological processes and drivers of range collapse, population decline eventual extinction steppe bison in Eurasia. Location Siberia. Time period Pleistocene Holocene. Major taxa studied Steppe (Bison priscus). Methods We configured 110,000 spatially explicit models (SEPMs) climate–human–steppe interactions Siberia, which we ran at generational time steps from 50,000 years ...

The European zebra mussel, Dreissena polymorpha (Pallas), has recently been introduced to North American freshwaters. Dreissena exhibits a wide range of population dynamics among different European lakes. In some lakes, long-term population size is fairly constant, while populations in other lakes can fluctuate greatly from year to year. Assessments of the potential ecological and economic effe...

© The Ecological Society of America www.frontiersinecology.org E change in North America has reinforced the importance of habitat modeling, to determine the habitat preferences and potential geographic distributions of invasive species in terrestrial (Stohlgren et al. 2006) and aquatic (Williamson et al. 2008) systems. The diatom Didymosphenia geminata is a single-celled alga (Bacillariophyceae...

a r t i c l e i n f o Heathlands are man-made habitats and their decline during the last century can be contributed to shifts in both agricultural and management practices as well as to hydrological and atmospheric changes. As a result, many heathland sites, including the Kalmthoutse Heide in Belgium, were included in the European Natura 2000 program, a network of protected areas across the Eur...

Abstract Context The amount and configuration of habitat are independent but tightly linked landscape characteristics which often confounded in ecological studies. Differentiating the effects each characteristic is critical for conservation, because mechanisms by they influence populations distinct. While studies that have measured separately found former to be more important, a subset these su...

The increasing pace of investments across academia and industry in the areas of pharmacometrics and systems pharmacology has the potential to profoundly impact drug discovery and development efficiency. In addition, it is being recognized that model-based approaches have also increasingly become important in regulatory decision making.1–3 For example, an analysis of 198 new drug application and...

Many bird species show spatial or habitat segregation of the sexes during the non-breeding season. One potential ecological explanation is that differences in bill morphology favour foraging niche specialisation and segregation. Western sandpipers Calidris mauri have pronounced bill size dimorphism, with female bills averaging 15% longer than those of males. The sexes differ in foraging behavio...
