Abundant variation in microsatellites of the parasitic nematode Trichostrongylus tenuis and linkage to a tandem repeat [PDF]

open access: yes, 2006
An understanding of how genes move between and within populations of parasitic nematodes is important in combating the evolution and spread of anthelmintic resistance.

Dialect Formation in Ghost Bats: Genetic, Geographic and Morphological Drivers of Social and Echolocation Call Divergence

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Dialect formation in the vocal repertoire of the ghost bat Macroderma gigas was investigated by comparing acoustic, geographic, genetic and morphological distances among colonies in the Northern Territory Australia. Dialects were detected in all vocalisation types examined, and while genetic (and geographic distance) explained some of the variation ...

A new species of Muscicapa flycatcher from Sulawesi, Indonesia.

open access: yesPLoS ONE, 2014
The Indonesian island of Sulawesi, a globally important hotspot of avian endemism, has been relatively poorly studied ornithologically, to the extent that several new bird species from the region have been described to science only recently, and others ...

Unravelling the diversity of the Crassiphialinae (Digenea: Diplostomidae) with molecular phylogeny and descriptions of five new species

open access: yesCurrent Research in Parasitology and Vector-Borne Diseases, 2021
Crassiphialinae Sudarikov, 1960 is a large subfamily of the Diplostomidae Poirier, 1886 with a complex taxonomic history. It includes a diversity of species parasitic in the intestines of avian and mammalian definitive hosts worldwide.

Hybridization between two recently diverged Neotropical passerines: The Pearly-bellied Seedeater Sporophila pileata, and the Copper Seedeater S. bouvreuil (Aves, Passeriformes, Thraupidae).

open access: yesPLoS ONE, 2020
The small Neotropical finches called capuchinos are outstanding because they have experienced one of the most recent and explosive avian radiations ever documented for birds. Despite very low morphological and niche divergence among species, many of them

Reproductive Isolation and Cryptic Introgression in a Sky Island Enclave of Appalachian Birds [PDF]

open access: yes, 2013
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.

Genetic Divergence of an Avian Endemic on the Californian Channel Islands. [PDF]

open access: yesPLoS ONE, 2015
The Californian Channel Islands are near-shore islands with high levels of endemism, but extensive habitat loss has contributed to the decline or extinction of several endemic taxa. A key parameter for understanding patterns of endemism and demography in

The hitchhiker's guide to avian malaria [PDF]

open access: yes, 2006
The ecological mechanisms underlying the dispersal of parasites are poorly understood, which is of particular concern in view of currently emerging infectious diseases.

Phylogeny, systematics and evolution of mimicry patterns in Neotropical limenitidine butterflies

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The most comprehensive phylogeny for Adelpha reveals that it is not monophyletic, supporting the description of the new genus Adelphina for the alala‐group. The rate of mimicry evolution increases towards the tropics, consistent with the hypothesis of stronger biotic interactions near the equator.
