Various methods have been used to estimate the amount of above ground forest biomass across landscapes and to create biomass maps for specific stands or pixels across ownership or project areas. Without an accurate estimation method, land managers might end up with incorrect biomass estimate maps, which could lead them...
This article argues that the international criminal justice system fails to sufficiently address conflict-related sexual violence in two critical ways: [1] by advocating a pro-prosecution, “end impunity” approach (defined as holding perpetrators accountable through criminal, civil, administrative or disciplinary proceedings) which applies the prevailing Euro-American model of justice designed to...
Gas hydrates, pervasive in continental margin sediments, are expected to release methane in response to ocean warming, but the geographic range of dissociation and subsequent flux of methane to the ocean are not well constrained. Sediment column thermal models based on observed water column warming trends offshore Washington (USA) show...
Polycyclic aromatic hydrocarbons (PAHs) are present in the environment as complex mixtures with components that have diverse carcinogenic potencies and mostly unknown interactive effects. Non-additive PAH interactions have been observed in regulation of cytochrome P450 (CYP) gene expression in the CYP1 family. To better understand and predict biological effects of...
Tropical dry forests are the most threatened forest type in the world yet a paucity of research about them stymies development of appropriate
conservation actions. The Paran~a River Basin has the most significant dry forest formations in the Cerrado biome of central Brazil
and is threatened by intense land conversion...
Seamounts are a ubiquitous feature of the seafloor but relatively little is known about their internal structure. A seamount preserved in the Franciscan mélange of California suggests a sequence of formation common to all seamounts. Field mapping, geophysical measurements, and geochemical analyses are combined to interpret three stages of seamount...
Vegetation structure is important in structuring avian communities. In the sagebrush biome, where continued habitat loss is thought to threaten shrusteppe-obligate birds, both remotely sensed and field-acquired measures of big sagebrush (Artemisia tridentata) cover have proven valuable in understanding avian abundance. Differences in structure between the exotic annual cheatgrass (Bromus...

The fisheries literature embodies critical assumptions about fisherman attitudes and motivations. Common assumptions are that populations of fisherman are homogeneous in motivation and decision making and that they behave in a myopic fashion, ignoring the effects of their fishing activities on the fishery resource. The results of a survey of...
