Biological nitrogen fixation (BNF) is a key ecological process that can restore nitrogen (N) lost in wildfire and shape the pace and pattern of post-fire forest recovery. To date, there is limited information on how climate and soil fertility interact to influence different pathways of BNF in early forest succession....

Stephanie Yelenik, Steven Perakis, and David Hibbs. 2013. Regional constraints to
Marine diseases are becoming more frequent, and tools for identifying pathogens and disease
reservoirs are needed to help prevent and mitigate epizootics. Meta-transcriptomics
provides insights into disease etiology by cataloguing and comparing sequences from suspected
pathogens. This method is a powerful approach to simultaneously evaluate both the
viral and bacterial...

BACKGROUND: We compared 24-hour waist-worn accelerometer wear time characteristics of 9-11 year old children
in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) to similarly aged U.S. children
providing waking-hours waist-worn accelerometer data in the 2003-2006 National Health and Nutrition Examination
Survey (NHANES).
METHODS: Valid cases were...
The composition of the continental crust is closely tied to subduction zone magmatism. Elevated oxygen fugacity (fO₂) plays a central role in fostering crystallization of oxide minerals and thereby aids in generating the calc-alkaline trend of iron depletion that characterizes the continents. Along continental margins, arc magmas erupt through continental...

Contributing to the worldwide biodiversity crisis are emerging infectious diseases, which can lead to extirpations and extinctions of hosts. For example, the infectious fungal pathogen Batrachochytrium dendrobatidis (Bd) is associated with worldwide amphibian population declines and extinctions. Sensitivity to Bd varies with species, season, and life stage. However, there is...

Biotic resistance is the idea that native species negatively affect the invasion success
of introduced species, but whether this can occur at large spatial scales is poorly
understood. Here we re-evaluated the hypothesis that native large-bodied grouper
and other predators are controlling the abundance of exotic lionfish (Pterois volitans/miles) on...

Chromosomal rearrangements may complicate construction of Arabidopsis with multiple TDNA-insertion mutations. Here, crossing two lines homozygous for insertions in AtREV3 and AtPOLH (chromosomes I and V, respectively) and selfing F1 plants yielded non-Mendelian F2 genotype distributions: frequencies of +/++/+ and 1/1 2/2 progeny were only 0.42 and 0.25%. However, the...
