Genetic Adaptation to Brackish Water and Spawning Season in European Cisco. [PDF]

open access: yesMol Ecol
ABSTRACTHow species adapt to diverse environmental conditions is essential for understanding evolution and the maintenance of biodiversity. The European cisco (Coregonus albula) is a salmonid that occurs in both fresh and brackish water, and this together with the presence of sympatric spring‐ and autumn‐spawning lacustrine populations provides an ...

Spawning Locations of Pallid Sturgeon in the Missouri River Corroborate the Mechanism for Recruitment Failure

open access: yesFishes, 2023
Conservation propagation of pallid sturgeon (Scaphirhynchus albus) upstream of Fort Peck Reservoir, MT, USA, has successfully recruited a new generation of spawning-capable pallid sturgeon where there would otherwise be fewer than 30 remaining wild ...

Spawning aggregation dynamics of brown-marbled grouper and camouflage grouper at a remote Indian Ocean atoll

open access: yesEndangered Species Research, 2013
The protection of grouper spawning aggregations is a global conservation issue: populations of many grouper species are threatened with collapse due to exploitation of this critical life history behaviour by fisheries.

The reproductive potential of yellowfin tuna (Thunnus albacares Bonnaterre, 1788) caught in the eastern part of the Indian Ocean [PDF]

open access: yesE3S Web of Conferences, 2021
Knowledge of reproduction biology provides valuable information to better understanding population dynamics, including a population's resilience to fishing. The yellowfin tuna reproductive biology in the eastern Indian Ocean was studied by analyzing some

Reproductive phenology of the Chesapeake Bay blue crab population in a changing climate

open access: yesFrontiers in Ecology and Evolution
Global temperatures are rising across marine ecosystems in response to climate change. Marine and estuarine-dependent species including the blue crab, Callinectes sapidus, may adapt to warming temperatures phenologically, by shifting the seasonal timing ...
