A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, EarlyView.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Three in one-multiple faunal elements within an endangered european butterfly species [PDF]

, 2015
Ice ages within Europe forced many species to retreat to refugia, of which three major biogeographic basic types can be distinguished: "Mediterranean", "Continental" and "Alpine / Arctic" species.

REPLY TO “ALLOZYMES AND SONG DIALECTS: A REASSESSMENT” [PDF]

Evolution, 1984
Our research centers on birdsong dialects, which are culturally transmitted (learned) vocal traditions. We evaluate the influence dialects have on the population biology of the White-crowned Sparrow, Zonotrichia leucophrys. Zink and Barrowclough (1984), in this issue, criticized our recent study (Baker et al., 1982b). Our null hypothesis (Baker et al.,

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Historical shifts, geographic biases, and biological constraints shape mammal species discovery

Journal of Systematics and Evolution, EarlyView.
Taxonomic descriptions of mammals have become more robust from 1990 to 2025, with increased specimen sampling, broader comparisons, and more integrative methods. However, disparities remain: tropical and small‐bodied species are less comprehensively described, reflecting ongoing geographic and biological biases.

Inheritance and linkage of allozymes in Juniperus phoenicea L. (Cupressaceae)

Acta Societatis Botanicorum Poloniae, 2014
Eight enzyme systems coding for 14 loci were assayed in Juniperus phoenicea. Mendelian inheritance was confirmed for allozymes at 10 loci (Fle 2, Gdh, Got 1, Idh, Mdh 1, Mdh 2, Men 1, Pgi, Pgm I, Pgm 2) by testing the fit of band-pattern segregation in ...

Ancestral Origin and Structural Characteristics of Non‐Syntenic Homologous Chromosomes in Abalones (Haliotis)

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Structural variation is increasingly recognised as a pivotal contributor to genomic diversity in marine invertebrates, yet its extent and evolutionary significance remain poorly characterised in many species. Haplotype‐phased genome assembly is an excellent resource for studying such variations by comparing homologous chromosomes.

GENETIC VARIABILITY IN THE MAGDALENA RIVER TURTLE, PODOCNEMIS LEWYANA (DUMÉRIL, 1852), IN THE MOMPOS DEPRESSION, COLOMBIA VARIABILIDAD GENÉTICA DE LA TORTUGA DEL RÍO MAGDALENA, PODOCNEMIS LEWYANA (DUMÉRIL, 1852), EN LA DEPRESIÓN MOMPOSINA, COLOMBIA

Actualidades Biológicas, 2008
Two populations of the endangered Magdalena River turtle, Podocnemis lewyana, separated by 55 km in the Mompos Depression were sampled to quantify levels of genetic variation and inspect for evidence of genetic structure.

Variation in gene copy number and polymorphism of the human salivary amylase isoenzyme system in Caucasians [PDF]

, 1992
The polymorphic patterns of human salivary amylase of a large number of individuals of Caucasian origin were determined by using isoelectric focusing and polyacrylamide gel electrophoresis.
