Salinity plays a limited role in determining rates of size evolution in fishes globally across multiple scales

Global Ecology and Biogeography, Volume 33, Issue 9, September 2024.
Abstract Aim Substantial progress has been made to map biodiversity and its drivers across the planet at multiple scales, yet studies that quantify the evolutionary processes that underpin this biodiversity, and test their drivers at multiple scales, are comparatively rare.

Comparison of traditional and molecular surveys of fish biodiversity in southern Te Wāhipounamu/Fiordland (Aotearoa/New Zealand)

Environmental DNA, Volume 6, Issue 1, January–February 2024.
At the remote UNESCO Word Heritage Site Te Wāhipounamu, we show that eDNA analysis is a highly sensitive tool with strong potential for biodiversity surveys, which is still limited by the unavailability of local reference data. We hope that by demonstrating the extend of divergence between eDNA and more traditional tools in a real‐life case study of a ...

Otolith and vertebral morphology of marine atherinid species (Atheriniformes, Atherinopsidae) coexisting in the southwestern Atlantic Ocean

Ciencias Marinas, 2010
Studies on marine ecosystems rely on the identification of fish prey species of piscivores (fish, aquatic mammals, and aquatic birds) based on their bones and otoliths. The stomach contents of piscivores show predation on marine atherinids of commercial

Post-mortem Fertilizing Capacity of Spermatozoid Chirostoma jordani (Atheriniformes: Atherinopsidae)

Genetics of Aquatic Organisms, 2023
Post-mortem fertilization is considered a technique in which semen is extracted from a dead male to fertilize the egg of a living female. Therefore, this technique can be an excellent option in the face of the loss of biodiversity of multiple animal species. The objective of this research is to implement post-mortem assisted reproduction in the charal,

Fish predation in the proximity of purse seine fishing lights: The case of Atherina boyeri (Actinopterygii: Atheriniformes: Atherinidae) in a Greek Lake [PDF]

Acta Ichthyologica et Piscatoria, 2018
Background. Purse seining with the use of light is among the most common fishing practices around the world, but there is lack of studies on the effect of light on the feeding of the target species in this kind of fishery and the possible consequences ...

Oocyte structure and ultrastructure in the Mexican silverside fish Chirostoma humboldtianum (Atheriniforme: Atherinopsidae)

Revista de Biología Tropical, 2007
The structural and ultrastructural features of gonads from endemic Mexican fish have received scarce attention. This study describes the histological and ultrastructural characteristics of the oocyte in Chirostoma humboldtianum. The ovary is asynchronic, and as such, most phases of oocyte development are found in the same ovary. The complete process of
