TL;DR: This paper investigated the relationship between lignin oxidation/demethylation and polysaccharide metabolism in a 32-week time series study of spruce sapwood inoculated with either of two basidiomycetes fungi (Postia placenta and Gloeophyllum trabeum).

Journal ArticleDOI
TL;DR: Field predation experiments and video observation show that tethered early benthic phase lobsters were attacked by demersal fishes and crabs significantly more often when unsheltered by cobble, and that this vulnerability declines dramatically with increasing body size.

TL;DR: Results show that Batrachochytrium can negatively affect some species of amphibians at the larval stage and not others, and the implications of interspecific variation in susceptibility to fungal infection are broad.
Abstract: As part of an overall biodiversity crisis many amphibian populations are in decline throughout the world. Numerous causes have been invoked to explain these declines. These include habitat destruction, cli- mate change, increasing levels of ultraviolet radiation, environmental contamination, and the introduction of non-native species and diseases. Several types of pathogens have been implicated in contributing to amphibian population declines: viruses, bacteria, oomycetes, and fungi. One particular fungus, the chytridiomycete Batra- chochytrium dendrobatidis may have caused amphibian population declines in several regions. This pathogen causes chytridiomycosis, which is fatal to newly metamorphic and adult amphibians of certain species. We present experimental evidence that larval stages may also be susceptible to exposure to Batrachochytrium .T here was, however, differential sensitivity to B. dendrobatidis in larvae we examined. In laboratory experiments, lar- va lw estern toads ( Bufo boreas )e xposed to B. dendrobatidis experienced increased mortality and behaviors that suggested they were affected by exposure compared with unexposed control tadpoles. Larvae of Cascades frogs ( Rana cascadae), bullfrogs ( R. catesbeiana), and Pacific treefrogs ( Hyla regilla) did not die after exposure to Batrachochytrium and appeared to behave normally. R. cascadae larvae exposed to B. dendrobatidis ,h owever, showed an increase incidence in mouthpart abnormalities, a characteristic effect of chytridiomycosis, com- pared with unexposed controls. These results show that Batrachochytrium can negatively affect some species of amphibians at the larval stage and not others. The implications of interspecific variation in susceptibility to fungal infection are broad.

TL;DR: This Policy Forum examines a range of issues associated with salvage harvesting policies after major natural disturbances such as fire, windstorms, and volcanic eruptions to help guide where, when, how, and if salvage harvesting takes place.
Abstract: The authors of this Policy Forum examine a range of issues associated with salvage harvesting policies after major natural disturbances such as fire, windstorms, and volcanic eruptions. Although natural disturbances can have important benefits for ecosystems, salvage harvesting can have major negative impacts on ecosystem recovery, the persistence of elements of biota, and the maintenance of key ecological processes. Better informed policies are needed to guide where, when, how, and if salvage harvesting takes place.

TL;DR: This paper showed that mytilid taxa are closely related to vent and seep taxa, and that this entire group is divergent from other Mytilidae, and suggested that decomposing wood and bone may have served as "steps" for the introduction of mytilids to vents and seeps.
Abstract: Symbiont-containing mussels (Mytilidae) are found at hydrothermal vents and cold seeps on the ocean floor, but it is not known whether these taxa represent an ancient lineage endemic to these surroundings or are more recent invaders Here we show that several small and poorly known mussels, commonly found on sunken wood and whale bones in the deep sea, are closely related to vent and seep taxa, and that this entire group is divergent from other Mytilidae Our results indicate that vents and seeps were recently invaded by modern mytilid taxa and suggest that decomposing wood and bone may have served as ‘steps’ for the introduction of mytilid taxa to vents and seeps
