Socio‐Economic and Ecological Drivers of the Spread of Non‐Native Tilapia (Oreochromis niloticus) Species in Kenya

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Nile tilapia (Oreochromis niloticus) is the dominant non‐native fish species in Kenya's inland waters, but its spread reflects a coupled socioecological process rather than a simple biological invasion. This review examines the socio‐economic, governance and ecological drivers of its expansion within a socioecological systems and invasion ...

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 8, Page 887-893, October 2026.
Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

Analysis of repetitive DNA sequences in the sex chromosomes of Oreochromis niloticus

, 2003
In the Nile tilapia, Oreochromis niloticus, sex determination is primarily genetic, with XX females and XY males. While the X and Y chromosomes (the largest pair) cannot be distinguished in mitotic chromosome spreads, analysis of comparative ...

Effects of Reduced Precipitation and Water Level Variability on Phytoplankton Dynamics and Thermal Structure in a Large Tropical Reservoir

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Drought is one of the most severe and complex natural hazards causing changes in water balance and impeding crucial water‐dependent ecosystem services. Over the last 25 years, multiple severe droughts linked to El Niño events have affected the Zambian and Zimbabwean regions.

Beyond Occurrence: Evidence Gaps for Non‐Native Freshwater Fishes in Brazilian Drylands

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Non‐native freshwater fishes are widely reported in inland waters, but occurrence records are often interpreted together with stronger evidence of establishment, reproduction, spread, pathways and impacts. This can overstate what published records support, especially in regions where reservoirs, river‐basin transfers and artificial ...

Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

Fisheries Management and Ecology, Volume 33, Issue 5, Page 1044-1056, October 2026.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.
