Understanding species interactions among top marine predators and interactions with their prey can provide important insight into community-level responses to changing prey availability and the role of apex predators as indicators of ecosystem change. On

Species assembly in model ecosystems, II: Results of the assembly process [PDF]
In the companion paper of this set (Capitan and Cuesta, 2010) we have developed a full analytical treatment of the model of species assembly introduced in Capitan et al. (2009).

Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Trophic ecology is an important aspect to consider when studying interactions between species, especially in ecologically similar species. We studied the trophic ecology of three sympatric insectivorous lizards in a dune system in the Eastern Iberian ...

Intrapopulation niche partitioning in a generalist predator limits food web connectivity [PDF]
Predators are increasingly recognized as key elements in food webs because of their ability to link the fluxes of nutrients and energy between spatially separated food chains.

Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.

Feeding habits of otters living on three moors in the Pannonian ecoregion (Hungary) [PDF]
Diet composition and feeding habits of Eurasian otters (Lutra lutra) living on three moors (Balata, Nagyberek and Feherviz) in Hungary were studied over two years using spraint analysis (n = 199, 503 and 3 15 samples from the three moors, respectively ...

Stable isotopes reveal differences in diet among reed bunting subspecies that vary in bill size [PDF]
Reed bunting Emberiza schoeniclus subspecies vary considerably in bill size and shape and seem to be at an early stage of speciation, in which bill might be indirectly causing reproductive isolation.

Climate change is significantly affecting biodiversity, and organisms that depend on external temperature – such as ectotherms – are particularly vulnerable to these effects. Microhabitats provide refuge for species, thereby reducing exposure to thermal and hydric stress under climate change.

Feeding Biology of Pectoral Sandpiper Calidris Melanotos (Birds: Scolopacidae) In the Floodplain of the Paraná River, Argentina [PDF]
This study focuses upon the nourishing biology of the Pectoral Sandpiper at the floodplain of the Paraná river during spring and summer. Trophic spectrum, feeding selectivity and efficiency, extent of the trophic niche, circadian rhythm of feeding ...
