Introduction: Threats that affect the avian diversity on Galápagos Islands are increasing. We evaluated threats such as climate change and severe weather, human intrusions disturbance, biological resource use, invasive other problematic species, genes diseases, pollution, geological events loss of genetic in relation with species enlisted both international national (Ecuador) IUCN Red List, which can be used sentinel ecosystem. Here, status threatened for next ten years (present time up to...
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,...
Abstract Objective Gray Snapper Lutjanus griseus constitute a significant recreational fishery and minor commercial throughout the Gulf of Mexico. The overall stock appears healthy based on results most recent assessment; in fact, shifting climate conditions have led to range expansions subsequent population growth north‐central Mexico, region for which full suite basic biological data is currently lacking this species. This work presents comprehensive study age, growth, maturity, mortality...
Climate change and marine pollution are intertwined in the Galapagos’ living laboratory, where unabated anthropogenic is reshaping evolution Anthropocene.
