Applying molecular genetic data at different scales to support conservation assessment of European Habitats Directive listed species: A case study of Eurasian otter in Austria

open access: yesEvolutionary Applications, 2023
Evaluating intraspecific genetic structure and diversity is fundamental to assessing a species’ conservation status, but direct incorporation of such information into legal frameworks such as the EU's Habitats Directive is surprisingly rare.

Intraspecific Phylogeography Across the Point Conception Biogeographic Boundary [PDF]

open access: yesEvolution, 1998
Recent studies of intraspecific phylogeography have suggested that the geographic location of genetic discontinuities, or phylogeographic breaks, may frequently coincide with biogeographic boundaries. The concordance is hypothesized to reflect similarity in the processes governing species boundaries and intraspecific lineage boundaries.

Cranial and mandibular shape variation in the genus Carollia (Mammalia: Chiroptera) from Colombia: biogeographic patterns and morphological modularity [PDF]

open access: yesPeerJ, 2015
Neotropical bats of the genus Carollia are widely studied due to their abundance, distribution and relevance for ecosystems. However, the ecomorphological boundaries of these species are poorly differentiated, and consequently correspondence between ...

Phylogenomics Reveals the Evolutionary History of Phytolacca (Phytolaccaceae)

open access: yesFrontiers in Plant Science, 2022
Phytolacca is the largest genus of Phytolaccaceae. Owing to interspecific hybridization, infraspecific variation, and apparent weak genetic control of many qualitative characters, which have obscured boundaries between species, the classification and ...

A COMPARATIVE STUDY OF ASYMMETRIC MIGRATION EVENTS ACROSS A MARINE BIOGEOGRAPHIC BOUNDARY [PDF]

open access: yesEvolution, 2001
In many nonclonal, benthic marine species, geographic distribution is mediated by the dispersal of their larvae. The dispersal and recruitment of marine larvae may be limited by temperature gradients that can affect mortality or by ocean currents that can directly affect the movements of pelagic larvae.
