Latin American Journal of Aquatic Research, 2014 An experiment was conducted to evaluate the effect of temperature on the intensity of predation upon snails. The experiment was run for 60 days using 15 cement tanks with water temperatures of 18, 22, 26, 30 and 34°C in a completely randomized design ...

Rapid morphological change in multiple cichlid ecotypes following the damming of a major clearwater river in Brazil. [PDF]
Evol Appl, 2020 Abstract While anthropogenic disturbances can have damaging effects on biodiversity, they also offer an opportunity to understand how species adapt to new environments and may even provide insights into the earliest stages of evolutionary diversification. With these topics in mind, we explored the morphological changes that have occurred across several

A meta‐analytic review of monoterpene for fish anaesthesia
Fish and Fisheries, Volume 24, Issue 3, Page 367-380, May 2023., 2023 Abstract The use of anaesthetic agents has been increasing to address the welfare needs of different fish species in scientific and aquaculture practices. MS‐222 is the most used synthetic anaesthetic but some limitations and side effects have been reported.

Ecology and Evolution, Volume 11, Issue 24, Page 18342-18356, December 2021., 2021 The success generalist species in urban systems is often related to a plastic diet and feeding‐related traits that allow them to take advantage of a variety of food subsidies provided by humans in cities. The classification of a species as generalist is commonly based on mean estimates of diet and feeding traits.

Molecular Ecology, Volume 30, Issue 8, Page 1880-1891, April 2021., 2021 Abstract The visual system of vertebrates has greatly contributed to our understanding of how different molecular mechanisms shape adaptive phenotypic diversity. Extensive work on African cichlid fishes has shown how variation in opsin gene expression mediates diversification as well as convergent evolution in colour vision.

Urbanization can increase the invasive potential of alien species
Journal of Animal Ecology, Volume 89, Issue 10, Page 2345-2355, October 2020., 2020 This paper looks at how urbanization enhances the success of invaders by changing species traits. The authors find that urbanization provides high food quality and quantity, which allows invasive guppies to increase body size and condition, number of offspring and population density. This suggests that urbanization promotes a highly invasive phenotype.
