Climate-driven changes in biotic interactions can profoundly alter ecological
communities, particularly when they impact foundation species. In marine systems,
changes in herbivory and the consequent loss of dominant habitat forming species can
result in dramatic community phase shifts, such as from coral to macroalgal
dominance when tropical fish herbivory decreases,...

Carbonate communities:The activity of anaerobic methane oxidizing microbes facilitates
precipitation of vast quantities of authigenic carbonate at methane seeps. Here we demonstrate
the significant role of carbonate rocks in promoting diversity by providing unique habitat
and food resources for macrofaunal assemblages at seeps on the Costa Rica margin
(400–1850 m)....

Anthropogenic and natural stressors often interact to affect organisms. Amphibian populations are undergoing unprecedented declines and extinctions with pesticides and emerging infectious diseases implicated as causal factors. Although these factors often co-occur, their effects on amphibians are usually examined in isolation. We hypothesized that exposure of larval and metamorphic amphibians...

Trophic interactions within and among species vary widely across spatial scales and species’ ontogeny. However, the drivers and implications of this variability are not well understood. Juvenile Chinook salmon Oncorhynchus tshawytscha have a wide distribution, ranging from northern California to the eastern Bering Sea in North America, but it is...
Capture-recapture studies offer a powerful tool to assess abundance, survival and population rate of change (λ). A previous capture-recapture study, based on DNA profiles, estimated that the IUCN-listed Endangered Oceania population of humpback whales had a superpopulation size of 4329 whales (95% confidence limits, CL: 3345, 5315) and λ =...

Emerging application areas such as air pollution in megacities, wind energy, urban security, and operation of unmanned aerial vehicles have intensified scientific and societal interest in mountain meteorology. To address scientific needs and help improve the prediction of mountain weather, the U.S. Department of Defense has funded a research effort—the...
Microbial communities are responsible for the bulk of biogeochemical processing in temporary headwater streams, yet there is still relatively little known about how community structure and function respond to periodic drying. Moreover, the ability to sample temporary habitats can be a logistical challenge due to the limited capability to measure...
