Diet-related cranial variation in modern humans is well documented on a regional scale,
with ample examples of cranial changes related to the agricultural transition. However, the …

Males of all reed frog species (Anura: Hyperoliidae) have a prominent, often colourful, gular
patch on their vocal sac, which is particularly conspicuous once the vocal sac is inflated …

Stable carbon (δ13C) and nitrogen (δ15N) isotopes and total mercury (Hg) were used to
investigate diet and resource use among Greenland sharks (Somniosus microcephalus) and …

Freshwater fishes often show large amounts of body shape variation across divergent
habitats and, in most cases, the observed differences have been attributed to the …

This study adopts an ecomorphological approach to test the utility of body shape as a
predictor of niche relationships among a stream fish assemblage of the Tickfaw River (Lake …

This study describes the seasonal feeding habits of different size classes of Cathorops spixii
and Cathorops agassizii along an estuarine ecocline and the food overlap when different …

Bones of Pleuronectiformes (flatfish) are often not identified to species due to the lack of
diagnostic features on bones that allow adequate distinction between taxa. This hinders in …

Body shape variation should play a central role in determining the feeding ability of a fish
species. We tested whether variations in feeding resource use of sympatric and closely …

In this study, clonal lines from North American resident and migratory populations of rainbow
trout Oncorhynchus mykiss adapted to different geographical conditions and with different …

Seasonal freshwater discharge was important for defining habitat utilization by different
ontogenetic phases of Stellifer brasiliensis and Stellifer stellifer along the estuarine ecocline …
