Echoes of Evolution in Holocentridae: Harmony Between Phylogeny, Morphology and Acoustics

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Using phylogenetic, morphological, and acoustic data from 53 species, we reconstructed the evolution of acoustic communication in nocturnal reef fishes of the family Holocentridae. Our results reveal two major clades with distinct sound‐producing morphologies and acoustic features, and suggest a three‐step diversification process involving the ...

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

Journal of Animal Ecology, Volume 95, Issue 8, Page 1326-1338, August 2026.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Desert cichlids

Natura
Cichlids were given their name by the French zoologist Charles Lucien Bonaparte (1803-1857), a nephew of Napoleon, who borrowed the term from the Greek κίχλη (kichle), a word that in origin had the broad meaning of “wrasse” (a fish) or “thrush” (a bird).

Dietary utilisation of protein and energy from fresh and ensiled coffee pulp by the Nile tilapia, Oreochromis niloticus

Brazilian Archives of Biology and Technology, 2003
Dietary protein and energy utilisation of diets containing fresh and ensiled coffee pulp were studied on 3.2 ± 0.2 g Nile tilapia for 28 days. Diets formulation and feeding were designed on the basis of daily dietary protein and energy allowance.

Plasticity in parental care: Interspecific competitor cues shape biparental cooperation in a burying beetle

Journal of Animal Ecology, Volume 95, Issue 8, Page 1358-1371, August 2026.
Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Effects of Brazilian Pepper Tree (Schinus terebinthifolius Raddi) Ethanolic Leaf Extract on Growth Performance and Expression of Intestinal Immune-Related Genes in Nile Tilapia (Oreochromis niloticus)

Biology
This study investigated the ethanolic leaf extract of Brazilian pepper tree (Schinus terebinthifolius Raddi) for its metabolite composition and effects on growth performance and intestinal immune gene expression in Nile tilapia (Oreochromis niloticus ...

Growth and histomorphological responses of Chindongo socolofi to the long‐term replacement of fish meal with defatted Tenebrio molitor meal

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract The long‐term suitability of defatted Tenebrio molitor larvae meal (TM) as a substitute for fish meal (FM) protein was evaluated in Chindongo socolofi over a 170‐day feeding period. Six isonitrogenous (38% crude protein) and isoenergetic (4396 kcal kg−1) diets were formulated, in which TM protein replaced FM protein at 0% (control), 20%, 40 ...

The Integrated Genomic Architecture and Evolution of Dental Divergence in East African Cichlid Fishes (Haplochromis chilotes x H. nyererei)

G3: Genes, Genomes, Genetics, 2017
The independent evolution of the two toothed jaws of cichlid fishes is thought to have promoted their unparalleled ecological divergence and species richness.

Inbreeding in a Fission–Fusion Equid Decreases Following an Increase in the Number and Redistribution of Water Sources

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Social structures and habitat configuration influence inbreeding in wild populations. In harem‐forming, female‐defence polygynous equids, social organization promotes inbreeding avoidance, but this has not been studied in fission–fusion, resource‐defence equid species.
