Los cromosomas mitóticos y meióticos del pez tropical Petenia splendida (Cichlidae)
Revista de Biología Tropical, 2008 Para describir los cromosomas del cariotipo en mitosis y meiosis de la mojarra tenguayaca P. splendida, se procesaron 60 larvas y doce jóvenes (seis hembras y seis machos) procedentes de Tabasco, México.

Ecology and Evolution, Volume 15, Issue 4, April 2025.Six Labeobarbus species occur in the Middle Luhoho, a left‐bank affluent of the Lowa River, including two chiselmouth species (Labeobarbus brauni, L. longidorsalis) and three rubberlip species (L. caudovittatus, L. longifilis, L. paucisquamatus), as well as an intermediate phenotype referred to as the smiling phenotype.

Sexual Dimorphism in Fin Size and Shape in North American Killifish
Ecology and Evolution, Volume 15, Issue 4, April 2025.Sexual dimorphism is pervasive in North American killifish in the size and shape of their dorsal and anal fins. These fins perform multiple functions, including grasping females during spawning, dominance displays towards rival males, and courtship towards females. Sexual selection may share a common direction across this group.

Molecular Ecology Resources, Volume 25, Issue 3, April 2025.ABSTRACT Despite substantial reductions in the cost of sequencing over the last decade, genetic panels remain relevant due to their cost‐effectiveness and flexibility across a variety of sample types. In particular, single nucleotide polymorphism (SNP) panels are increasingly favoured for conservation applications.

Demonstrating the Theory of Ecological Speciation in Cichlids
PLoS Biology, 2006 The geological history of Africa’s Lake Victoria, the second largest freshwater lake in the world, provided the raw materials for investigating one of the most compelling hypotheses for the origin of species: ecological speciation. After drying out three times over its 400,000-year history, the lake refilled about 15,000 years ago, and the few cichlid ...

Ecology Letters, Volume 28, Issue 4, April 2025.We investigate how non‐native species can impact native species in a 30‐year time scale by estimating the co‐occurrence between native and non‐native species pairs. We show that interannual variability of non‐native species abundance could be more important than long‐term abundance trends in determining the effects of non‐native species through time ...
