Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 8, August 2025.ABSTRACT Cape fur seals (Arctocephalus pusillus pusillus) are important apex predators and indicators of ecological health. Historically, their populations were severely reduced by the activities of sealers and guano collectors but has since increased due to legislation controlling, then banning these activities.

Accounting for molecular stochasticity in systematic revisions: species limits and phylogeny of Paroaria [PDF]
, 2009 Different frameworks have been proposed for using molecular data in systematic revisions, but there is ongoing debate on their applicability, merits and shortcomings.

Population structure of avian malaria parasites
Ecology and Evolution, 2019 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

, 1999 We examined patterns of variation in skeletal morphometrics (29 characters), allozymes (34 loci), mitochondrial DNA (mtDNA) restriction sites (n = 74) and fragments (n = 395), and mtDNA sequences (1,739 bp from cytochrome b, ND2, ND6, and the control ...

Morphometric Variation as an Indicator of Genetic Interactions between Black-capped and Carolina Chickadees at a Contact Zone in the Appalachian Mountains [PDF]
, 2000 We studied hybridization and introgression between Black-capped (Poecile atricapillus) and Carolina (P. carolinensis) chickadees along two transects in the Appalachians using four genetic markers and multivariate analysis of morphology.

Gene Expression Shifts in Emperor Penguin Adaptation to the Extreme Antarctic Environment
Molecular Ecology, Volume 34, Issue 15, August 2025.ABSTRACT Gene expression can accelerate ecological divergence by rapidly tweaking the response of an organism to novel environments, with more divergent environments exerting stronger selection and supposedly, requiring faster adaptive responses. Organisms adapted to extreme environments provide ideal systems to test this hypothesis, particularly when ...

Geographic range size and evolutionary age in birds [PDF]
, 2000 Together with patterns of speciation and extinction, post-speciation transformations in the range sizes of individual species determine the form of contemporary species-range-size distributions.

A key to selected rockfishes (Sebastes spp.) based on mitochondrial DNA restriction fragment analysis [PDF]
, 2006 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 ...
