Pseudomonas fluorescens WH6 secretes a germination-arrest factor (GAF) that we have
identified previously as 4-formylaminooxyvinylglycine. GAF irreversibly inhibits germination of the
seeds of numerous grassy weeds and selectively inhibits growth of the bacterial plant pathogen
Erwinia amylovora. WH6-3, a mutant that has lost the ability to produce GAF, contains a...

Mercury (Hg) is a globally distributed environmental
contaminant with a variety of deleterious effects
in fish, wildlife, and humans. Breeding songbirds may be
useful sentinels for Hg across diverse habitats because they
can be effectively sampled, have well-defined and small
territories, and can integrate pollutant exposure over time
and space....

A new functional gene database, FOAM (Functional
Ontology Assignments for Metagenomes), was developed
to screen environmental metagenomic sequence
datasets. FOAM provides a new functional
ontology dedicated to classify gene functions relevant
to environmental microorganisms based on Hidden
Markov Models (HMMs). Sets of aligned protein
sequences (i.e. ‘profiles’) were tailored to...

The reality confronting ecosystem managers today is one of heterogeneous, rapidly transforming landscapes,
particularly in the areas more affected by urban and agricultural development. A landscape management
framework that incorporates all systems, across the spectrum of degrees of alteration, provides a fuller set of
options for how and when to...

Honey bee colony losses are a major concern in the USA and across the globe. Long-term data on losses
are critical for putting yearly losses in context. US colony loss surveys have been conducted yearly since the winter
of 2006–2007. Here, we report the results from the eighth annual survey...

We estimate fluid sources around a subducted seamount along the northern Hikurangi subduction
margin of New Zealand, using thermomechanical numerical modelling informed by
wedge structure and porosities from multichannel seismic data. Calculated fluid sources are
input into an independent fluid-flow model to explore the key controls on overpressure generation
to...

Iron (Fe) and copper (Cu) are essential cofactors for microbial metalloenzymes, but little is known about the metalloenyzme inventory of anaerobic marine microbial communities despite their importance to the nitrogen cycle. We compared dissolved O₂ , NO₃⁻, NO₂⁻, Fe and Cu concentrations with nucleic acid sequences encoding Fe and Cu-binding...
