Evolutionary associations between sand seatrout (Cynoscion arenarius) and silver seatrout (C. nothus) inferred from morphological characters, mitochondrial DNA, and microsatellite markers [PDF]

open access: yes, 2009
The evolutionary associations between closely related fish species, both contemporary and historical, are frequently assessed by using molecular markers, such as microsatellites.

Interpreting the process behind endemism in China by integrating the phylogeography and ecological niche models of the Stachyridopsis ruficeps. [PDF]

open access: yesPLoS ONE, 2012
An area of endemism (AOE) is a complex expression of the ecological and evolutionary history of a species. Here we aim to address the principal drivers of avian diversification in shaping patterns of endemism in China by integrating genetic, ecological ...

Population Genetic Structure and Species Delimitation of a Widespread, Neotropical Dwarf Gecko [PDF]

open access: yes, 2019
Amazonia harbors the greatest biological diversity on Earth. One trend that spans Amazonian taxa is that most taxonomic groups either exhibit broad geographic ranges or small restricted ranges.

Evolutionary factors affecting the cross-species utility of newly developed microsatellite markers in seabirds [PDF]

open access: yes, 2015
Microsatellite loci are ideal for testing hypotheses relating to genetic segregation at fine spatio-temporal scales. They are also conserved among closely related species, making them potentially useful for clarifying interspecific relationships between ...

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.

The mitogenomes of Gelochelidon nilotica and Sterna hirundo (Charadriiformes, Sternidae) and their phylogenetic implications

open access: yesMitochondrial DNA. Part B. Resources, 2017
Gelochelidon nilotica and Sterna hirundo are two sympatric breeding species. The mitogenomes of G. nilotica and S. hirundo are 16,748 bp and 16,707 bp in size.

Accounting for molecular stochasticity in systematic revisions: species limits and phylogeny of Paroaria [PDF]

open access: yes, 2009
Different frameworks have been proposed for using molecular data in systematic revisions, but there is ongoing debate on their applicability, merits and shortcomings.

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

open access: yesEnvironmental 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 ...

Evidence supporting the recent origin and species status of the Timberline Sparrow

open access: yes, 1999
The Timberline Sparrow (Spizella taverneri), although originally described as a species, is currently classified as a subspecies of the more widespread Brewer\u27s Sparrow (S. breweri). We investigated the taxonomic status and recent evolutionary history

Host associations, biogeography, and phylogenetics of avian malaria in southern African waterfowl [PDF]

open access: yes, 2012
The relevance of spatial variation in the environment and host communities for parasite community composition is poorly documented, creating a need for additional case studies from which general principles can be developed.
