Gametic isolation in guppies ( Poecilia reticulata ) [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2006
Post-mating reproductive isolating mechanisms may be among the earliest reproductive barriers to emerge among incipient species. Trinidadian guppy, Poecilia reticulata , populations in the Caroni and Oropouche drainages in Northern Trinidad exhibit marked genetic divergence and provide an ...

Getting into hot water:sick guppies frequent warmer thermal conditions [PDF]

, 2016
Ectotherms depend on the environmental temperature for thermoregulation and exploit thermal regimes that optimise physiological functioning. They may also frequent warmer conditions to up-regulate their immune response against parasite infection and/or ...

Dimensions of dace dynamics: temporal variation in abundance and survival of an imperiled desert fish guide habitat restoration

Restoration Ecology, EarlyView.
Abstract Introduction Desert fishes are vulnerable to anthropogenic environmental alterations that degrade habitat and reduce water availability, but these same fishes benefit from restoration actions that reverse the causes of decline. Ash Meadows speckled dace (Rhinichthys osculus nevadensis) is a federally endangered minnow endemic to the Mojave ...

Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.

Impacts of Salinity on Growth, Physiology and Tissue Integrity of Nile Tilapia: Implications for Coastal Aquaculture Under Climate Change

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT Climate change is responsible for salinity intrusion in coastal areas, which is significantly threatening the sustainability of aquaculture. This investigation focused on evaluating growth performance, proximate composition, blood morphology and histopathological modifications in Nile tilapia (Oreochromis niloticus) exposed to varying salinity
