A pharyngeal jaw and loose pharyngeal teeth from Prairie Creek, Indiana, and loose pharyngeal teeth and two basioccipital pharyngeal processes from Bell Cave, Alabama, appear to be those of Moxostoma hubbsi (Copper Redhorse). Among suckers, only M. carinatum, M. hubbsi, M. robustum, and M. ugidatli have molariform teeth on their pharyngeal jaws, with M. hubbsi having the teeth of the largest relative size. Measurements of most...

Labeo is the third most diverse genus of African cyprinids and is widely distributed across the continent. Labeo parvus , a small species originally described from the Congo basin, has been considered the only species of the L. forskalii group distributed across five African ichthyofaunal provinces (Nilo‐Sudan, Congo, Cuanza, and Upper and Lower Guinea). However, morphological similarity between L. parvus and numerous congener...

Aim Previous research on how climatic niches vary across species ranges has focused on a limited number of species, mostly invasive, and has not, to date, been very conclusive. Here we assess the degree of niche conservatism between distant populations of native alpine plant species that have been separated for thousands of years. Location European A lps and F ennoscandia. Methods Of the studied pool of 888 terrestrial vascula...

Recent studies from mountainous areas of small spatial extent ( 2 ) suggest that fine‐grained thermal variability over tens or hundreds of metres exceeds much of the climate warming expected for the coming decades. Such variability in temperature provides buffering to mitigate climate‐change impacts. Is this local spatial buffering restricted to topographically complex terrains? To answer this, we here study fine‐grained therm...
