Abstract Southern Pacific humpback whales ( Megaptera novaeangliae ) breed in subtropical and tropical waters off Peru the south to Nicaragua north. The effect of warming oceans on whale distribution breeding areas remains unclear. We modeled spatial coast Ecuador relation environmental variables. analyzed temporal variability sighting rates (animals/hour) a (Manabí, 1996–1999) (Esmeraldas, 2001–2019) ground. At regional scale, we found presence was more likely shallow over continental...
We examined how dietary factors recorded by C and N influence Hg uptake in 347 individuals of yellowfin tuna (Thunnus albacares), an important subsistence resource from the Galápagos Marine Reserve (Ecuador) Ecuadorian mainland coast 2015-2016. found no differences total (THg) measured red muscle between two regions seasonal differences, likely due to age fish slow elimination rates Hg. Our THg concentrations are comparable those other studies Pacific (0.20-9.60 mg/kg wet wt), but a subset...
Yellowfin tuna, Thunnus albacares , is an important global fishery and of particular importance in the Eastern Pacific Ocean (EPO). According to 2019 Inter-American Tropical Tuna Commission (IATTC) assessment, yellowfin tuna within EPO a single stock, being managed as one stock. However, previous studies indicate site fidelity, or limited home ranges, which suggests potential for multiple stocks EPO, was supported by population genetic study using microsatellites. If numerous are present,...
