Anhydrobiosis represents an extreme example of tolerance adaptation to water loss, where an organism can survive in an ametabolic state until water returns. Here we report the first comparative analysis examining the genomic background of extreme desiccation tolerance, which is exclusively found in larvae of the only anhydrobiotic insect, Polypedilum vanderplanki. We compare the genomes of P. v...
How ecological communities respond to predicted increases in temperature will determine the extent to which Earth's biodiversity and ecosystem functioning can be maintained into a warmer future. Warming is predicted to alter the structure of natural communities, but robust tests of such predictions require appropriate large-scale manipulations of intact, natural habitat that is open to dispersa...
We studied changes in macrobenthic communities following the environmental clean-up of metal-polluted (cadmium, nickel, and cobalt) sediments in Foundry Cove, a small inlet within the Hudson River estuary of New York. We used a BACI-style experiment to test the hypotheses that high levels of cadmium in sediments change macrobenthic assemblages relative to unpolluted areas, and removal of metals...
Between March and November 1984, Silver Creek, a small tributary of the Mahoning River in northeastern Ohio, eroded into and through a small lacustrine deposit of glacial silt. During this erosional/ siltation episode, the stream was very turbid and siltation was observed at least 5 km below the source of silt. Only a few individuals of the caddisfly, Neophylax, the mayflies, Isonychia and Sten...
Abstract Invasive alien species impacts might be mediated by environmental factors such as climatic warming. For invasive predators, multiple predator interactions could also exacerbate or dampen ecological impacts. These effects may especially pronounced in highly diverse coastal ecosystems that are prone to profound and rapid regime shifts. We examine emergent of warming on the strength intra...
