Comparing Aggression Levels in Jack Dempsey Cichlids Based on Variation of Haitat Structure [PDF]
, 2013 Jack Dempsey cichlids, Rocio octofasciata, are native to South America and known for their aggressive behaviors. These fish are popular in freshwater aquariums, but can act aggressively towards other fish.

Ecology and Evolution, Volume 16, Issue 9, September 2026.We have examined the phylogenetic relationships, genomic structure, admixture, and historical gene flow among the endemic charrs from the Kronotskoe‐Uzon water system in Kamchatka, in order to reconstruct their evolutionary history. We found that this unique diversity formed in the post‐LGM—Holocene time as a result of several waves of Salvelinus malma

The effect of male coloration on female mate choice in closely related Lake Victoria cichlids (Haplochromis nyererei complex) [PDF]
, 1998 We studied the effect of male coloration on interspeciÆc female mate choice in two closely related species of haplochromine cichlids from Lake Victoria. The species differ primarily in male coloration. Males of one species are red, those of the other are

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Born This Way: Individuality Is Seeded Before Birth and Robust to Ecological Stress
Ecology Letters, Volume 29, Issue 9, September 2026.We reared and recorded behaviours of clonal Amazon mollies in standardized environments, with and without predation stress, from birth through week four of life, to understand how the developmental environment influences the emergence of behavioural individuality.

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response
Journal of Fish Biology, Volume 109, Issue 3, Page 1760-1770, September 2026.Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.
