Ecophenotypic Variation of Midas Cichlid, Amphilophus citrinellus (Gunther, 1864), in Lake Batur, Bali, Indonesia [PDF]

Brazilian Journal of Biology
Cichlid fishes exhibit rapid adaptive radiations with significant diversification rates in response to ecological variability, i.e., ecological opportunity or geographical isolation.

Infectious Diseases Management in Small‐Scale Freshwater Aquaculture in West Africa: Lessons for Low‐ and Middle‐Income Countries

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Infectious diseases are an increasing threat to food security, small‐scale livelihoods and the sustainability of aquaculture in low‐ and middle‐income countries (LMICs). In sub‐Saharan Africa, aquaculture is expanding rapidly but production systems often remain fragile.

An introgressed wing pattern acts as a mating cue. [PDF]

, 2015
Heliconius butterflies provide good examples of both homoploid hybrid speciation and ecological speciation. In particular, examples of adaptive introgression have been detected among the subspecies of Heliconius timareta, which acquired red color pattern

Hypotheses for the Adaptive Maintenance of Phenotypic Polymorphisms

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Phenotypic polymorphisms offer easily observable diversity ideal for empirical and theoretical exploration, but developing and comparing hypotheses for the adaptive maintenance of polymorphism can be a challenge. Here, we propose a framework categorizing polymorphisms based on (i) one of five distinct types of maintenance selection and (ii) the context

Land Cover, Land Use, and Climate Change Impacts on Endemic Cichlid Habitats in Northern Tanzania

Remote Sensing, 2017
Freshwater ecosystems are among the most threatened on Earth, facing environmental and anthropogenic pressures often surpassing their terrestrial counterparts. Land use and land cover change (LUCC) such as degradation and fragmentation of the terrestrial

Going Beyond Body Size in Fish Acoustic Communication

Ecology and Evolution, Volume 16, Issue 5, May 2026.
ABSTRACT In this response to Dr. Eric Parmentier's comments on our paper ‘“What Does the Anemonefish Say?”: Investigating Amphiprion percula's Acoustic Behaviour’, we correct and clarify Dr. Parmentier's affirmations. Firstly, we address the statistical ‘problems’ by clarifying our statistical approach, highlighting the advantages of GLMMs in ...

Hybrid Horizons: Screening Hybridisation Through Nuclear Environmental DNA

Molecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Effective monitoring of hybrid zones is essential for understanding evolutionary dynamics and mitigating species loss caused by human‐mediated hybridisation. Conventional methods rely on sampling numerous individuals, which is costly, time‐consuming and often impractical for rare or elusive species.

Analysis of BAC end sequences of tilapia (Oreochromis niloticus) using in silico approaches (W046) [PDF]

, 2011
Tilapias are the second most important fish group in aquaculture and a primary source of animal protein for millions of people in developing countries. Over the past years a great effort has been done to increase the genomic tools in tilapia by obtaining

Recombination suppression in plant adaptation and speciation

New Phytologist, Volume 250, Issue 4, Page 2061-2077, May 2026.
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 ...
