ABSTRACT Aim Knowledge of the main drivers of population differentiation is crucial for understanding evolutionary processes and preserving biodiversity. While primarily studied in terrestrial habitats, the mechanisms operating in the marine realm are less well understood.

Population structure of avian malaria parasites
The geographic distribution of genetic diversity in malaria parasite populations (Apicomplexa: Haemosporida) presumably influences local patterns of virulence and the evolution of host‐resistance, but little is known about population genetic structure in

Reproductive Isolation and Cryptic Introgression in a Sky Island Enclave of Appalachian Birds [PDF]
Reproductive isolation is central to the speciation process, and cases where the strength of reproductive isolation varies geographically can inform our understanding of speciation mechanisms.

ABSTRACT Aim Modelling demographic changes through time in combination with phylogenomic reconstructions provides a promising avenue to better understand the impact of past environmental changes on biogeographic patterns, yet we have only begun to exploit this potential.

A key to selected rockfishes (Sebastes spp.) based on mitochondrial DNA restriction fragment analysis [PDF]
Larval and juvenile rockfishes (Sebastes spp.) are difficult to identify using morphological characters. We developed a key based on sizes of restriction endonuclease fragments of the NADH dehydrogenase-3 and -4 (ND3/ND4) and 12S and 16S ribosomal RNA ...

The hitchhiker's guide to avian malaria [PDF]
The ecological mechanisms underlying the dispersal of parasites are poorly understood, which is of particular concern in view of currently emerging infectious diseases.

The complete mitochondrial genome sequence of the little egret (Egretta garzetta)
Many phylogenetic questions in the Ciconiiformes remain unresolved and complete mitogenome data are urgently needed for further molecular investigation.

Extensive polymorphism and geographical variation at a positively selected MHC class II B gene of the lesser kestrel (Falco naumanni) [PDF]
Understanding the selective forces that shape genetic variation in natural populations remains a high priority in evolutionary biology. Genes at the major histocompatibility complex (MHC) have become excellent models for the investigation of adaptive ...
