2023年1月23日 · After wolf colonization, we quantified shifts in foraging behavior with DNA metabarcoding of 689 wolf scats and stable isotope analyses, both revealing a dietary switch from Sitka black-tailed deer...

We documented a transboundary food web interaction resulting from the recolonization of sea otters in Icy Straight, Alaska, which provided an ample marine subsidy to island wolves, and subsequently caused extirpation of a terrestrial ungulate.

2023年3月10日 · In this paper, we use a bifactorial experiment to isolate the influence of terrestrial predator extirpation on the space use (proactive behavior) and antipredator response (reactive behavior) of a model prey species, the eastern fox squirrel (Sciurus niger) towards terrestrial and avian predators.

2024年2月12日 · In this study, we analyzed functional connectivity for coyotes (Canis latrans) in Toronto, Canada, given that they are wide-ranging terrestrial mesopredators and have the potential to be an umbrella species (Breckheimer et al. 2014).

2021年9月14日 · Removal or loss of top-predators has been predicted to cause cascading negative effects for ecosystems, including mesopredator release. However, reliable evidence for these processes in...

2024年6月24日 · We synthesize global evidence for climate-driven changes in spatial predator–prey overlap resulting from species redistribution across marine and terrestrial domains. We show that spatial...

2024年12月18日 · We tested this hypothesis by investigating the escape behavior of spotted fringe-fingered lizards (Acanthodactylus maculatus) approached by a person (i.e. terrestrial predator), with or without a raptor model (i.e. aerial predator), and recording data on escape agility, display movements and refuge use.

2025年1月21日 · Here, we investigated the propensity of a giant water bug, Abedus, to prey preferentially on terrestrial taxa in fishless, intermittent streams and discuss the significance of this preference in the context of ecosystems that have highly fluctuating P/A ratios.

Sea otters (Enhydra lutris) and wolves (Canis lupus) are two apex predators with strong and cascading effects on ecosystem structure and function. After decades of recovery from near extirpation, their ranges now overlap, allowing sea otters and wolves to interact for the first time in the scientific record.
