Pipits and wagtails by Per Alström( Book )

4 editions published between 2000 and 2003 in English and held by 143 WorldCat member libraries worldwide

Pipits & wagtails of Europe, Asia and North America : identification and systematics by Per Alström( Book )

12 editions published between 2001 and 2010 in English and held by 106 WorldCat member libraries worldwide

Wagtails are noted for their bold plumage patterns and extensive racial variation. Pipits are a large and difficult group which invariably causes vexation to birders on both sides of the Atlantic. This guide covers the 26 species of northern hemisphere pipits and wagtails in detail. It treats identification in the field and in the hand, and includes colour plates, detailed distribution maps and sonograms of songs and calls

Evolution of ultraviolet vision in the largest avian radiation the passerines by Anders Ödeen( )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

Background: Interspecific variation in avian colour vision falls into two discrete classes: violet sensitive (VS) and ultraviolet sensitive (UVS). They are characterised by the spectral sensitivity of the most shortwave sensitive of the four single cones, the SWS1, which is seemingly under direct control of as little as one amino acid substitution in the cone opsin protein. Changes in spectral sensitivity of the SWS1 are ecologically important, as they affect the abilities of birds to accurately assess potential mates, find food and minimise visibility of social signals to predators. Still, available data have indicated that shifts between classes are rare, with only four to five independent acquisitions of UV sensitivity in avian evolution. Results: We have classified a large sample of passeriform species as VS or UVS from genomic DNA and mapped the evolution of this character on a passerine phylogeny inferred from published molecular sequence data. Sequencing a small gene fragment has allowed us to trace the trait changing from one stable state to another through the radiation of the passeriform birds. Their ancestor is hypothesised to be UVS. In the subsequent radiation, colour vision changed between UVS and VS at least eight times. Conclusions: The phylogenetic distribution of SWS1 cone opsin types in Passeriformes reveals a much higher degree of complexity in avian colour vision evolution than what was previously indicated from the limited data available. Clades with variation in the colour vision system are nested among clades with a seemingly stable VS or UVS state, providing a rare opportunity to understand how an ecologically important trait under simple genetic control may co-evolve with, and be stabilised by, associated traits in a character complex

Explosive radiation and spatial expansion across the cold environments of the Old World in an avian family by Baoyan Liu( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Our objective was to elucidate the biogeography and speciation patterns in an entire avian family, which shows a complex pattern of overlapping and nonoverlapping geographical distributions, and much variation in plumage, but less in size and structure. We estimated the phylogeny and divergence times for all of the world's species of Prunella based on multiple genetic loci, and analyzed morphometric divergence and biogeographical history. The common ancestor of Prunella was present in the Sino-Himalayan Mountains or these mountains and Central Asia-Mongolia more than 9 million years ago (mya), but a burst of speciations took place during the mid-Pliocene to early Pleistocene. The relationships among the six primary lineages resulting from that differentiation are unresolved, probably because of the rapid radiation. A general increase in sympatry with increasing time since divergence is evident. With one exception, species in clades younger than c. 3.7 my are allopatric. Species that are widely sympatric, including the most recently diverged (2.4 mya) sympatric sisters, are generally more divergent in size/structure than allo-/parapatric close relatives. The distributional pattern and inferred ages suggest divergence in allopatry and substantial waiting time until secondary contact, likely due to competitive exclusion. All sympatrically breeding species are ecologically segregated, as suggested by differences in size/structure and habitat. Colonizations of new areas were facilitated during glacialperiods, followed by fragmentation during interglacials-contrary to the usual view that glacial periods resulted mainly in fragmentations
