Gyrodactylus salinae n. sp. (Platyhelminthes: Monogenea) infecting the south European toothcarp Aphanius fasciatus (Valenciennes) (Teleostei, Cyprinodontidae) from a hypersaline environment in Italy [PDF]

Parasites & Vectors, 2011
Background Historically, non-native species of Gambusia (Poeciliidae) have been used to control larval stages of the Asian tiger mosquito, Stegomyia albopicta Reinert, Harbach et Kitching, 2004 throughout Italy.

Global Patterns and Drivers of Freshwater Fish Extinctions: Can We Learn From Our Losses? [PDF]

Glob Chang Biol
Nearly one‐third of freshwater fish species are currently at risk of extinction, with 100 species already lost. This study examines extinction patterns over the past 165 years, identifying habitat modification and loss, pollution, and invasive species as key drivers.

eDNA metabarcoding reveals differences in fish diversity and community structure in heterogeneous habitat areas shaped by cascade hydropower. [PDF]

Ecol Evol, 2023
Freshwater ecosystems are under great threat from humans, among which habitat heterogeneity is the most obvious, being one of the important reasons for the decline of fish diversity. This phenomenon is particularly prominent in the Wujiang River, where the continuous rapids of the mainstream have been divided into 12 mutually isolated segments by 11 ...

Variations in fish body and scale shape among Aphanius dispar (Cyprinodontidae) populations: insights from a geometric morphometric analysis

Caspian Journal of Environmental Sciences, 2017
Phenotypic variations in fish body and scale shape were investigated among the three populations of Aphanius dispar (Rüppell, 1829) in Southern Iran through the use of landmark-based geometric morphometric analyses.

Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou. [PDF]

Ecol Evol
Monitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.

Surprising spatiotemporal stability of a multi-peak fitness landscape revealed by independent field experiments measuring hybrid fitness. [PDF]

Evol Lett, 2020
Abstract The effect of the environment on fitness in natural populations is a fundamental question in evolutionary biology. However, experimental manipulations of both environment and phenotype at the same time are rare. Thus, the relative importance of the competitive environment versus intrinsic organismal performance in shaping the location, height,

Sexual Dimorphism in Fin Size and Shape in North American Killifish. [PDF]

Ecol Evol
Sexual dimorphism is pervasive in North American killifish in the size and shape of their dorsal and anal fins. These fins perform multiple functions, including grasping females during spawning, dominance displays towards rival males, and courtship towards females. Sexual selection may share a common direction across this group.
