Species identity of Gambusia (Pisces: Poeciliidae) introduced to Slovenia

Natura Sloveniae, 2007
On the basis of morphology of the gonopodium and fin ray counts it was determined that the introduced mosquitofish in Slovenia belong to the species Gambusia holbrooki Girard, 1859 rather than G. affinis (Baird & Girard, 1858).

Hypersalinity drives physiological and morphological changes in Limia perugiae (Poeciliidae)

Biology Open, 2016
A fundamental question in biology is how an organism's morphology and physiology are shaped by its environment. Here, we evaluate the effects of a hypersaline environment on the morphology and physiology of a population of livebearing fish in the genus ...

Faster Weight Growth in Invasive Mosquitofish <i>Gambusia holbrooki</i> and <i>Gambusia affinis</i> (Poeciliidae) Under Climate Change. [PDF]

Ecol Evol
Global populations of western mosquitofish G. affinis are more sensitive to climatic variation than eastern mosquitofish G. holbrooki in terms of length‐weight allometries. Under climate change, the populations of G. affinis, especially those in East Asia and Eastern Europe, are expected to grow faster in weight, posing greater threats to native ...

Male Copulatory Structures in Reproductively Functional Female Live-Bearing Fish <i>Pseudopoecilia fria</i>. [PDF]

Ecol Evol
We recently discovered a population of the live‐bearing fish Pseudopoecilia fria (Cyprinodontiformes: Poeciliidae), in which females were found to possess gonopodia, reproductive organs normally exclusive to male fish that are used in the transfer of sperm in mating.

A Global Account of Established Non-Native Fish Species. [PDF]

Glob Chang Biol
This study compiles the most complete global database of non‐native fish species that have successfully established themselves in new freshwater and marine environments. It documents 1535 species across 193 countries, identifies their main introduction routes—such as aquarium trade, aquaculture, and artificial waterways—and highlights that many ...

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.

Oil Things Bright and Beautiful? How Hydrocarbon Pollution Impacts Guppy Ornamentation. [PDF]

Ecol Evol
Spatial variation in crude oil pollution in Trinidad leads to differing levels of pollutant exposure in connected guppy populations. Male guppy ornamentation is an important sexually selected trait affected by environmental changes. Measuring area and intensity of this ornamentation, we found guppies from anthropogenically polluted habitats had greater

Predator avoidance in extremophile fish [PDF]

, 2013
Extreme habitats are often characterized by reduced predation pressures, thus representing refuges for the inhabiting species. The present study was designed to investigate predator avoidance of extremophile populations of Poecilia mexicana and P ...

Pantanodontidae (Teleostei, Cyprinodontiformes), the sister group to all other cyprinodontoid killifishes as inferred by molecular data

Zoosystematics and Evolution, 2018
Pantanodon, containing two African extant species and four European fossil species, for a long time had an uncertain position among the Cyprinodontiformes due to its peculiar morphology. In the last decades, Pantanodon has been considered closely related

Predator-induced changes of female mating preferences: innate and experiential effects [PDF]

, 2011
Background: In many species males face a higher predation risk than females because males display elaborate traits that evolved under sexual selection, which may attract not only females but also predators. Females are, therefore, predicted to avoid such
