Silverside fishes in Chile, abundant in marine and freshwater habitats, are classified in two genera: Odontesthes and Basilichthys. Both genera have widespread distributions across southern South America, with marine origins.

DNA barcoding the ichthyofauna of the Beibu Gulf: Implications for fisheries management in a seafood market hub. [PDF]
The fish fauna of the beibu gulf, one of the largest sea food hubs in Southeast Asia, is characterized here by DNA barcoding. The 1080 DNA barcodes analyzed show concordance between morphological identifications and DNA‐based species delimitation. Lower level of diversity detected here compared to historical observations is concordant with the stock ...

Ultrastructure of fresh and post thawed sperm of pejerrey Odontesthes bonariensis (Atheriniformes) [PDF]
In the present study it was showed for the first time the ultrastructural morphology of O. bonariensis sperm using electron microscopy techniques. Different kinds of abnormalities were described in fresh and post thawed sperm caused by crogenic protocols.

The dwarf neon rainbowfish Melanotaenia praecox, a small spiny-rayed fish with potential as a new Acanthomorpha model fish: II. Establishment of a microinjection procedure for genetic engineering. [PDF]
Abstract Background Rainbowfish is a clade of colorful freshwater fish. Melanotaenia praecox is a small rainbowfish species with biological characteristics that make it potentially useful as an experimental model species. We anticipate that M. praecox could become a new model used in various fields, such as ecology, evolution, and developmental biology.

Where the Ends Meet: An Overview of Sex Determination in Atheriniform Fishes [PDF]
Atheriniform fishes have recently emerged as attractive models for evolutionary, ecological, and molecular/physiological studies on sex determination. Many species in this group have marked temperature-dependent sex determination (TSD) and yet many species also have a sex determinant gene that provides a strong drive for male differentiation.

The dwarf neon rainbowfish Melanotaenia praecox, a small spiny-rayed fish with potential as a new Acanthomorpha model fish: I. Fin ray ontogeny and postembryonic staging. [PDF]
Abstract Background Fish fins with highly variable color patterns and morphologies have many functions. In Actinopterygii, the free parts of fins are supported by “soft rays” and “spiny rays.” Spiny rays have various functions and are extremely modified in some species, but they are lacking in popular model fish such as zebrafish and medaka ...

Accurate estimates of reproductive parameters important in understanding life history evolution and conservation of small fishes are dependent upon careful assignment of ovarian phases. We review oocyte development and the ovarian cycling process using both macroscopic and histological approaches which incorporate the clutch concept.

This dataset was extracted from case studies of animal and plant conservation translocation published in the first six volumes (2008‐2018) of the IUCN/SSC's 'Global Reintroduction Perspectives' series. Alongside project metadata, it contains the following self‐reported information: select project strategies and methods; information relating to any ...

Abstract Trait‐based models of ecological communities and ecosystem functioning often fail to account for intraspecific variation in functional traits, assuming that intraspecific variability is negligible compared with interspecific variability. However, this assumption remains poorly tested across vertebrate animals where past studies routinely ...

Abstract Feeding specialisations are known to play an important role in the ecology and evolution of many organisms. In this study, we performed a comparative analysis based on the data of the gut content of eight species of the genus Limia (family Poeciliidae) to explore the potential role of feeding ecology in the radiation of this genus in the ...
