Abstract. Convergence, defined as lineages evolving to be more similar to one another than their ancestors due to selective pressures is a hallmark of adap

For organisms with biparental care, successful reproduction hinges on coordination between partners. Seabirds face an extreme coordination challenge because parents must schedule nest attendance on la...

Muscle architecture is a key determinant of muscle performance, informing the calculation of functional traits such as force production and excursion distance. Due to its importance in understanding ....

Abstract. Understanding reproductive isolation (RI) between lineages is a central goal of speciation research. While the strength of RI has been estimated

A new Yale-led study finds that while the outward appearance of woodland salamanders has changed little over millions of years, their physiology has evolved in striking ways.

Abstract. One puzzling feature of avian life histories is that individuals in many different lineages delay reproduction for several years after they finis

Abstract. The rate of evolution of a single morphological character is not homogeneous across the phylogeny and this rate heterogeneity varies between morp

The governor said public universities and state agencies may not seek new visas without permission through the end of the 2027 legislative session.

Patterns of evolutionary change in the fin and body shapes of fishes are strongly related to dietary ecology and locomotor mechanisms, and associations between shapes affects ecomorphological relation...

Abstract. Keratinized labial teeth of the oral apparatus are a conspicuous evolutionary novelty of anuran tadpoles. Although several comparative studies ha

Abstract. One puzzling feature of avian life histories is that individuals in many different lineages delay reproduction for several years after they finis

Biofluorescence is widespread in fishes. Here, the authors compile data on biofluorescence presence across teleost fishes and demonstrate that it may have originally evolved in eels 112 million years ...

Phylogenomics reveals a younger-than-expected age of reef fish diversification.

Climate change is a major threat to biodiversity. This study predicts that climate change will reshape Neotropical frog diversity, causing losses in phylogenetic diversity and phylogenetic endemism, w...

More than 1,600 readers answered our poll; many said they were looking for jobs in Europe and Canada.

Reproductive barriers can evolve despite gene flow. A combination of genomics and behavioural assays shows two mitonuclear incompatibilities originated via ancient hybridization that underlie hybrid i...

The advent of molecular phylogenetics has rapidly transformed the understanding of relationships within Acanthopterygii, the spiny-rayed fishes. Acanthopterygii includes most of the marine fish divers...
