The Early Development of the Blue‐Eye Cichlid, Cryptoheros spilurus (Cichliformes: Cichlidae)

open access: yesEvolution &Development, Volume 27, Issue 4, December 2025.
We document the early development of Cryptoheros spilurus, highlighting rapid cranial differentiation, sensory organ formation, and fin development. Ontogenetic allometry and ultrastructural traits reveal functional adaptations for early foraging and locomotion, offering insights into ecological success and the developmental basis of cichlid ...

How Do Morphological Traits and Abundance Reflect the Effects of Land Use Change in a Seasonal Floodable Savannah? A Dung Beetle Case in the Brazilian Pantanal

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 12, Page 1268-1277, December 2025.
We investigated the effects of land‐use change on the abundance and morphological traits (body mass, pronotum ratios, protibial size, elytra ratio, and pronotum–abdomen proportion) of two dung beetle species (Dichotomius bos and D. nisus) in the Brazilian Pantanal.

The Overlooked Link Between Different Resource Partitioning Strategies and Plant Species Richness in Tropical Alpine Ecosystems

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 12, December 2025.
ABSTRACT Aim Species coexistence is based on resource partitioning and modulates biodiversity patterns across climates, latitudes and altitudes. Resource partitioning can occur via niche size or separation in the geographic range or ecological niche. While resource partitioning promotes biodiversity, the impact of different partitioning strategies on ...
