Insights Into the Feeding Ecology of Young‐of‐the‐Year Bigeye Tuna (Thunnus obesus) in the Southwestern Atlantic Ocean

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Bigeye tuna (Thunnus obesus) is among the most prized tuna species sustaining fisheries worldwide. However, information on the feeding habits for the species is mostly restricted to the size range harvested by commercial fisheries. In this study, we report the diet composition of juvenile bigeye tuna schooling near the surface at night in the ...

Winter Diets of Pacific Salmon in the North Pacific

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT The winter feeding ecology of Pacific salmon and Steelhead trout in the North Pacific Ocean was investigated, with a focus on species‐specific diets and interannual and spatial variability in diet composition. We used results from the 2022 International Year of the Salmon Pan‐Pacific Expedition to examine diet composition across the North ...

Past research and future directions in understanding how birds use their sense of smell

open access: yesIbis, EarlyView.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

Environmental and Evolutionary Forces Shaping Penguin Geographic Limits

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Penguins are seabirds exclusively found in the Southern Hemisphere, with their existence dating back to the late Cretaceous. Despite their exceptional dispersal capabilities, which allow them to inhabit a wide range of environments—from polar regions to temperate zones, and even near the Equator—penguins are absent in the Northern ...

Global Change Likely to Promote the Expansion of the Quagga Mussel (Dreissena bugensis) in Europe

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Invasive aquatic species are a pressing concern for environmental managers due to their significant impacts and high eradication costs. The Ponto‐Caspian region is a notable source of aquatic invasive species, with over 40 invaders currently affecting freshwater ecosystems throughout Europe.

Comparative studies on a zooplankton–fish model subjected to infection in zooplankton with varying rates of disease transmission

open access: yesFranklin Open
Eco-epidemiological models offer practical demonstrations of non-linear dynamics, enriching the realm of mathematical biology. The importance of viruses in oceanic plankton ecosystems is becoming more widely acknowledged.
