Epichloë typhina, a fungal endophyte of
cool season grasses, is heterothallic and an obligate
out-crosser. In areas of endemism, its spermatia are
moved between stromata of the two opposite mating
types through egg-laying activities of Botanophila flies.
In western Oregon, where the fungus was inadvertently
introduced into seed-production fields of...
Disease, overharvesting, and pollution have impaired the role of bivalves on coastal ecosystems, some to the point of functional extinction. An underappreciated function of many bivalves in these systems is shell formation. The ecological significance of bivalve shell has been recognized; geochemical effects are now more clearly being understood. A...

Recent studies hypothesize that some submarine slides fail via pressure-driven slow-slip deformation. To test this hypothesis, this study derives pore pressures in failed and adjacent unfailed deep marine sediments by integrating rock physics models, physical property measurements on recovered sediment core, and wireline logs. Two drill sites (U1394 and U1399)...
Lead (Pb) is a metabolic poison that can negatively influence biological processes, leading to illness and mortality
across a large spectrum of North American avifauna (>120 species) and other organisms. Pb poisoning can result from
numerous sources, including ingestion of bullet fragments and shot pellets left in animal carcasses, spent...

As long-standing keepers of democracy and information stewardship, library professionals are a natural fit for advocating and promoting sustainability within their communities. From seed libraries to Occupy Wall Street libraries, their view of sustainability extends beyond environmental concerns to include community activism, economic development, and social equity. Empowering people, facilitating...
