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

Current 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.

Revision of Madagascar's Dwarf Lemurs (Cheirogaleidae:Cheirogaleus): Designation of Species, Candidate Species Status and Geographic Boundaries Based on Molecular and Morphological Data [PDF]

, 2014
The genus Cheirogaleus, the dwarf lemurs, is a radiation of strepsirrhine primates endemic to the island of Madagascar. The dwarf lemurs are taxonomically grouped in the family Cheirogaleidae (Infraorder: Lemuriformes) along with the genera Microcebus,

Validating Airborne eDNA Using Manual Surveys, Acoustic Monitoring and Camera Traps to Detect Birds and Mammals in an Agroforestry Setting

Environmental DNA, Volume 7, Issue 6, November–December 2025.
In this study, we provide the first comparison of airborne eDNA with observer‐based surveys and passive acoustic monitoring, alongside camera traps, to monitor birds and mammals in a Dutch agroforestry system. Airborne eDNA showed the highest potential species diversity, detected many unique species–including invasive mammals–and complemented ...

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

PLoS 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

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

PLoS 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

Ancient DNA & stable isotope profiling of fossil eggshell [PDF]

, 2012
Eggshell is frequently encountered within palaeontological and archaeological deposits and due to various chemical and physical properties, it is highly valued as a substrate for geochronology, palaeodietary and palaeoecological applications. Despite the

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

, 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.

Genetic Differentiation in a Wide‐Ranging Tropical Seabird in the Indian Ocean Is Linked With Oceanographic Factors

Diversity and Distributions, Volume 31, Issue 11, November 2025.
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.

Genetic divergence between isolated populations of the North Island New Zealand Rifleman (Acanthisitta chloris granti) implicates ancient biogeographic impacts rather than recent habitat fragmentation

Ecology and Evolution, 2021
This research investigates the extent and causal mechanisms of genetic population divergence in a poorly flighted passerine, the North Island Rifleman or Titipounamu (Acanthisitta chloris granti).
