The Atlantic sea scallop (Placopecten magellanicus) supports valuable Canadian and US fisheries in the western North Atlantic, an area projected to experience ocean acidification and increased seawater temperatures due to global climate change. In the November issue of Frontiers, Stokesbury et al. describe how this bivalve mollusk is characteristically sensitive to changing physical conditions, and explain how establishing a baseline of scallop abundance will be important to help track regional environmental variability over time.
Species phenology plays a key role in determining mutualist interactions, such as those between plants and pollinators, and specialized species are expected to show a high level of synchrony with their partners. The Talamanca Hummingbird (Eugenes spectabilis) pictured on the November cover of Ecology is endemic to the montane forests of Costa Rica and western Panama. This species is one of four hummingbirds found in the páramo ecosystem in Costa Rica and presents a moderate ecological specialization in floral resource use; see Maglianesi et al. in this issue.
Predatory blue crabs (Callinectes sapidus) utilize oyster reefs throughout the Southeastern Atlantic Bight, eating oysters and eliciting anti-predator traits from oysters with consequences (commonly referred to as nonconsumptive eﬀects, NCEs) for oyster growth and reproduction. In the October issue of Ecosphere, Kimbro et al. report that statistically signiﬁcant NCEs are uncommon in natural settings and pale in importance to biogeographic gradients in predation pressure and oceanography.
The common mistfrog from the Australian Wet Tropics bioregion is one of three species of rainforest frogs that have recolonized uplands following outbreaks of the devastating fungal disease, chytridiomycosis. Bell et al. found that despite high infection risk in the uplands, lowland environmental refuges and connectivity across the disease risk gradient have enabled natural recovery. Their results are presented in the October issue of Ecological Applications.
Finzi et al. synthesized hundreds of thousands of carbon observations collected over the last quarter century at the Harvard Forest Long-Term Ecological Research site. They found that increasing oak (Quercus) dominance and climate change, particularly longer growing seasons, have accelerated the rate at which the forest is capturing carbon from the atmosphere. Their findings are presented in the November issue of Ecological Monographs.
