DOI: 10.1007/s00227-020-03699-6
Abstract: The El Niño Southern Oscillation (ENSO) is a recurrent climatic pattern with important ecological consequences for seabirds due to its impacts on the abundance and distribution of food resources. We investigated the effects of ENSO… read more here.

Cascading effects of predation risk under high organic and inorganic turbidity: impacts on individuals and shoals of a mesopredator fish
Sign Up to like & getrecommendations! Published in 2020 at "Aquatic Ecology"
DOI: 10.1007/s10452-020-09782-w
Abstract: We tested whether changes in water transparency caused either by precipitation-mediated sedimentation (inorganic turbidity) or eutrophication (organic turbidity) differently interact with top predator presence to determine predation rates, and individual decisions of mesopredators between foraging… read more here.

DOI: 10.1007/s12591-016-0307-9
Abstract: In ecology, disease in the top-predator population plays an important role for controlling chaotic dynamics of a predator-prey system. We modify Hastings and Powell’s (HP) (Hastings and Powell, Ecology 72:896–903, 1991 ) food chain model… read more here.

DOI: 10.1007/s40435-016-0255-9
Abstract: Food uptake ability of higher trophic level species are more complicated and interesting due to their choice and availability of food and consequently their growth. In the present study, the effect of top predator interference… read more here.

DOI: 10.1016/j.pocean.2018.03.007
Abstract: Abstract Most oceanographic systems, especially shelf ecosystems, are characterised by interannual variability in the timing, extent and intensity of their seasonal patterns. Such interannual variations have important consequences on top predator habitat preferences. Capitalising on… read more here.

Legacy Polybrominated Diphenyl Ethers (PBDEs) Trends in Top Predator Fish of the Laurentian Great Lakes (GL) from 1979 to 2016: Will Concentrations Continue to Decrease?

DOI: 10.1021/acs.est.9b00933
Abstract: Polybrominated diphenyl ethers (PBDEs) were widely used as fire retardants and have been detected throughout the Great Lakes (GL) ecosystem. The concentration trends (after fish age normalization) of PBDEs in top predator fish (lake trout… read more here.

Local-scale impacts of extreme events drive demographic asynchrony in neighbouring top predator populations

DOI: 10.1098/rsbl.2022.0408
Abstract: Extreme weather events are among the most critical aspects of climate change, but our understanding of their impacts on biological populations remains limited. Here, we exploit the rare opportunity provided by the availability of concurrent… read more here.

Environmental drivers of population-level variation in the migratory and diving ontogeny of an Arctic top predator

DOI: 10.1098/rsos.211042
Abstract: The development of migratory strategies that enable juveniles to survive to sexual maturity is critical for species that exploit seasonal niches. For animals that forage via breath-hold diving, this requires a combination of both physiological… read more here.

Top predator restricts the niche breadth of prey: effects of assisted colonization of Tasmanian devils on a widespread omnivorous prey

DOI: 10.1098/rspb.2022.2113
Abstract: Few landscape-scale experiments test the effects of predators on the abundance and distribution of prey across habitat gradients. We use the assisted colonization of a top predator, the Tasmanian devil (Sarcophilus harrisii), to test the… read more here.
