Size‐selective mortality evolutionarily alters collective behaviour in response to predation risk in a zebrafish (Danio rerio) harvest‐induced selection model

Journal of Fish Biology, EarlyView.
Abstract Intensive multigenerational size‐selective mortality has been found to alter collective properties like shoaling via evolutionary adaptations of individual‐level behavioural traits. For example, experimental populations of zebrafish (Danio rerio) experiencing intensive large size‐selective mortality over multiple generations developed less ...

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

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.

Recombination suppression in plant adaptation and speciation

New Phytologist, EarlyView.
Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Histological Characterization and Oocyte Development in Pearlspot, Etroplus suratensis (Bloch, 1790) From Vembanad Lake, Kerala, India

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT This study is the first to elucidate the oocyte growth pattern of Etroplus suratensis through detailed gonad histology. Ovary samples from different maturity stages were collected from October 2023 to September 2024 from cage culture systems installed in Vembanad Lake, Kumbalangi, Kerala, India.

The impact of urbanisation on social behaviour: a comprehensive review

Biological Reviews, Volume 101, Issue 2, Page 1003-1035, April 2026.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

Tagging Very Small Fish: Two Effective and Low Impact Methods

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 3, Page 213-224, April 2026.
ABSTRACT Identifying individuals over time and across contexts is essential in many scientific fields. There are a variety of well‐established methods for uniquely marking individuals (e.g., visible implant elastomer, barcodes, paint). However, for some species, life history stages, and/or experiments, existing methods are not sufficient.

Tetraopes Milkweed Beetle Genomes Elucidate the Adaptive Basis of a Temperate Coevolutionary Radiation

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...
