Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...

Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Microclimate mediates the strength and direction of avian biotic interactions
Theory predicts that the strength and direction of species interactions can shift from being competitive in benign environments toward being facilitative in stressful environments. However, the environmental context dependency of species interactions has rarely been tested in animal communities.

Responses of Antarctic seabird populations to past climate change
Higher‐order predators such as Antarctic seabirds serve as ecological indicators of environmental change and provide a crucial trophic link between marine and terrestrial ecosystems. Despite their prevalence and significance in the Antarctic ecosystem, there is a lack of understanding of the impacts of major regime shifts in paleoclimate on flighted ...

A global latitudinal decline in breeding site fidelity emerges from a single biome
Species that breed in multiple years can either return to the same location to reproduce between seasons or disperse to a different location. Previous studies have shown that breeding site fidelity varies with species‐ and individual‐specific traits, but much of the observed variation remains unexplained.
