Ideal values of bond angles and lengths used as external restraints are crucial for the successful
refinement of protein crystal structures at all but the highest of resolutions. The restraints in
common usage today have been designed based on the assumption that each type of bond or
angle has a...
1. Seeding native plants is a key management practice to counter land degradation across
the globe, yet the majority of seeding efforts fail, limiting our ability to accelerate ecosystem
recovery.
2. Recruitment requires transitions through several seed and seedling stages, some of which
may have overriding influences on restoration outcomes....
Effects of climate change, retreating glaciers, and changing storm patterns on debris flow hazards concern
managers in the Cascade Range (USA) and mountainous areas worldwide. During an intense rainstorm in
November 2006, seven debris flows initiated from proglacial gullies of separate basins on the flanks of Mount
Rainier. Gully heads...
Dwarf mistletoes (Arceuthobium species) influence many processes within forested ecosystems, but few studies have examined their distribution in relation to climate. An analysis of 1549 forested plots within a 14.5 million ha region of southeast Alaska provided strong indications that climate currently limits hemlock dwarf mistletoe (Arceuthobium tsugense (Rosendahl) G.N....

The factors that control the explosivity of silicic volcanoes are critical for hazard assessment, but are often poorly constrained for specific volcanic systems. Mount Hood, Oregon, is a somewhat atypical arc volcano in that it is characterized by a lack of large explosive eruptions over the entire lifetime of the...

The first through fifth instars of the gypsy moth were tested for development to adults on
326 species of dicotyledonous plants in laboratory feeding trials. Among accepted plants,
differences in suitability were documented by measuring female pupal weights. The majority of
accepted plants belong to the subclasses Dilleniidae, Hamamelidae, and...
