While marine hermit crabs are well known for being omnivorous filter feeders, less is known about the role they may play as active camion scavengers in intertidal ecosystems. Prior studies have revealed that intertidal hermit crabs can be attracted to chemical cues from gastropods(snails) killed by predators. Yet their attraction is usually assumed to be driven primarily by the availability of new shells for shelters rather than by food. Researchers conducted field experiments to assess hermit crabs potential role as generalist carrion scavengers on the California coast, examining their speed of attraction and the size of the aggregations they formed in response to chemical cues from freshly smashed gastropods and mussels both of which indicated available carrion. Compared to all other marine species, hermit crabs were the fastest to arrive at the provisioning sites. Hermit crabs also dominated the provisioning sites, accumulating in the largest numbers, with aggregations of up to 20 individuals, which outcompeted all other scavengers for carrion. Notably, hermit crabs arrived equally quickly for both smashed gastropod and mussel, even though the latter does not offer suitable shells for hermit crabs and even though the former only yields shell-related chemical cues over time frames longer than the experiments. These results thus suggest that shell availability is not the only, or even the primary reason marine intertidal hermit crabs aggregate at carrion sites; they also aggregate to forage, thereby playing an important role as active carrion scavengers in intertidal ecosystems.

In 1995, after an absence of nearly 10 years, wolves were reintroduced into Yellowstone National Park. During the wolf-free era, heavy browsing of aspen trees by elk populations spelled doom not only for the trees themselves but for a host of other creatures dependent on them, such as beavers, whose population in Yellowstone crashed after wolves were removed. Without beavers to create ponds, wetland ecosystems-aquatic plants, amphibians, birds-were devastated. When wolves retuned, grazers and browsers resumed normal patterns of behavior, preferring safer, open areas over the dense cover and streamsides where carnivores can lurk. Keeping elk wary and on the move, wolves gave aspen and other young trees the opportunity to grow and become reestablished.
