One Century of Breeding Bird Assessment by western travellers in Iran, 1876-1977
This article lists 99 articles on distribution of wild birds in Iran, which appeared
between 1876 and 1977 and which were published by authors writing in European
languages. Each paper has a reference number ...
Hybrids in divers (Gaviiformes)
The incidence of hybridisation in birds differs
greatly between orders and is expected to be low in orders
comprising few species. The divers or loons (Gaviiformes)
are a species-poor group in which ...
Low predictive power of mid-domain effect to explain geographic species richness patterns in Palearctic songbirds
In the study of diversity patterns, the Mid-domain effect (MDE),
which explains gradients in diversity solely on the basis of geometric
constraints, has emerged as a null-model against which
other ...
Ecomorphology of the wheatears (genus Oenanthe)
We used measurements of museum skins to assess morphological differences between
the 22 currently recognized species of wheatear and to identify correlations between
morphological features, behavioural traits ...
The mid-domain effect on the geographic species richness pattern of Palearctic songbirds
We tested a geometric constraint model, the mid domain effect (MDE), as an explanation for spatial gradient in species richness of Palearctic songbirds. A data set was created of digitized equal area distribution maps of ...
Species diversity and endemism: testing the mid-domain effect on species richness patterns of songbirds in the Palearctic Region
Explanation of the spatial distribution patterns in species
richness, and especially those of small-ranged species (endemics),
bears relevance for studies on evolution and speciation,
as well as for ...
