Mating and aggressive behaviour of Brachyrhaphis olomina (Cyprinodontiformes: Poeciliidae) [PDF]

Journal of Ethology, 2017
Abstract Despite the increasing interest in the use of intromittent male genitalia and coercive mating behaviour in poeciliids, detailed studies of the mating behaviour of most species in this family are lacking. We describe here the mating and aggressive behaviours of Brachyrhaphis olomina, and correlate them with the condition of the female’

Combining morphology, scanning electron microscopy, and molecular phylogeny to evaluate the taxonomic power of scales in genus Aphanius Nardo, 1827 (Teleostei: Cyprinodontidae)

Archives of Polish Fisheries, 2017
Scale morphology and its structural details were studied with morphometry, geometric morphometrics, and scanning electron microscopy in five Iranian Aphanius species and examined comparatively with molecular phylogeny. Scales were cycloid and circular in

Inner ear morphology in the Atlantic molly Poecilia mexicana--first detailed microanatomical study of the inner ear of a cyprinodontiform species. [PDF]

PLoS ONE, 2011
BACKGROUND: Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.

Development of the caudal-fin skeleton reveals multiple convergent fusions within Atherinomorpha

Frontiers in Zoology, 2021
Background The caudal fin of teleosts is a highly diverse morphological structure and a valuable source of information for comparative analyses. Within the Atherinomorpha a high variation of conditions of the caudal-fin skeleton can be found. These range

Viviparity stimulates diversification in an order of fish

Nature Communications, 2016
Live birth and an annual life cycle potentially enable access to new ecological niches and subsequent species diversification. Here, Helmstetter et al.build the phylogeny for fish in the order Cyprinodontiformes and find that, though live birth and ...

First complete mitochondrial genome of the South American annual fish Austrolebias charrua (Cyprinodontiformes: Rivulidae): peculiar features among cyprinodontiforms mitogenomes [PDF]

BMC Genomics, 2015
Among teleosts, the South American genus Austrolebias (Cyprinodontiformes: Rivulidae) includes 42 taxa of annual fishes divided into five different species groups. It is a monophyletic genus, but morphological and molecular data do not resolve the relationship among intrageneric clades and high rates of substitution have been previously described in ...
