Transmissible tumours have been found in only a few types of animal, but there might be many more out there.

Scientists named this oddball creature after the Demogorgon from Stranger Things

Abstract. Insights into ecomorphology are enriched when investigating evolutionary correlations between ecologically and functionally important traits. How

The relative importance of genetic drift versus selection to evolutionary change has long been debated. This debate has mainly focused over long-time-scales (e.g. hundreds of thousands of generations)...

Effective population size (Ne) is a crucial parameter in the fields of evolutionary biology, conservation biology of endangered species, and selective breeding of domestic animals and crops, as it qua...

Peripheral and disjunct populations are often the result of historic geological changes in the landscape and because of the long temporal span of colonization or vicariance, they are often genetically...

Abstract. The hagfish eye is highly reduced, lacking pigment and a lens, and covered by soft tissue. The timing and mode of this loss of complexity remain

Salmonids have a remarkable ability to form sympatric morphs after postglacial colonisation of freshwater lakes. These morphs often differ in morphology, feeding and spawning behaviour. Here, we…

The European Red List provides a scientifically rigorous and evidence-based assessment of the regional extinction risk of selected European taxa. This includes all vertebrate species - fishes, amphibi...

The repeated evolution of parental care is often accompanied by shifts in the neural circuits and hormonal pathways that regulate motivation and aggre…

For over half a century, people in Central Africa have told tales of the fish seen climbing waterfalls, but these claims have never been officially confirmed. Now, these fish have finally been caught ...

Background Genome evolvability involves activation of transposable elements (TEs) that result in novel genomic rearrangements, including translocations, deletions, duplications, as well as larger stru...

Turquoise killifish are naturally short-lived vertebrates that serve as a model system for aging. The authors show that killifish exhibit age-related transformation in the immune system, which rapidly...

Researchers often use multiple genetic methods to estimate contemporary effective population size (Ne), but few formally combine estimates despite potential benefits for increasing precision. Maximis....

Abstract. Post-ejaculatory sexual selection in the form of cryptic female choice provides opportunities for females to bias paternity to favour preferred m

Analysis of the asexually reproducing Amazon molly Poecilia formosa and its sexually reproducing progenitors Poecilia mexicana and Poecilia latipinna reveals that it maintains a divergent mutational l...

Fossil polypterid elements have been recovered from the Upper Cretaceous (Maastrichtian) Maevarano Formation of Madagascar. These elements document th…

One of the most significant California water stories of this decade is the virtual extinction of the Delta Smelt in the wild and the collapse of the Sacramento-San Joaquin River Delta ecosystem that i...

Heredity - Different sex determination systems in two closely related Eurasian minnow (Phoxinus) species

Abstract. Phylogenetic comparative methods (PCMs) are fundamental tools for understanding trait evolution across species. While linear models are widely us

Witness the Klamath River’s transformation as dam removal restores salmon habitat, tribal lands, and cultural connections in this historic restoration.

Abstract. Transposable elements (TEs) are abundant selfish genetic elements that can mobilize in their host genome, causing DNA damage, mutations, and chro

Abstract. The deep sea is known for extreme biological conditions such as high pressure, little-to-no solar light and cold temperatures. Despite these chal

The contest is seeking creative ideas on how to use all parts of Great Lakes fish.

Achieving Diversity, Equity, Inclusion, and Accessibility (DEIA) in the aquatic sciences has been a chronic challenge, and while recent progress has b…

Abstract. Sex chromosome systems have evolved independently across the tree of life, at different times in the past, and the evolutionary consequences of l

Abstract. Understanding the ecological drivers and limitations of adaptive convergence is a fundamental challenge. Here, we explore how adaptive convergenc

Abstract. Methods for rapidly inferring the evolutionary history of species or populations with, genome-wide data are progressing, but computational constr
