Formal description of plant phenotypes and standardized annotation of gene expression and protein localization data require
uniform terminology that accurately describes plant anatomy and morphology. This facilitates cross species comparative
studies and quantitative comparison of phenotypes and expression patterns. A major drawback is variable terminology that is
used to describe...

Repetitive sequences present a challenge for genome sequence assembly, and highly similar segmental duplications may
disappear from assembled genome sequences. Having found a surprising lack of observable phenotypic deviations and
non-Mendelian segregation in Arabidopsis thaliana mutants in SEC10, a gene encoding a core subunit of the exocyst
tethering complex, we...

Exotic species dominate many communities; however the functional significance of species’ biogeographic origin remains highly contentious. This debate is fuelled in part by the lack of globally replicated, systematic data assessing the relationship between species provenance, function and response to perturbations. We examined the abundance of native and exotic plant...

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...

The exchange of carbon dioxide is a key measure of ecosystem metabolism and a critical intersection
between the terrestrial biosphere and the Earth’s climate. Despite the general agreement that
the terrestrial ecosystems in North America provide a sizeable carbon sink, the size and distribution
of the sink remain uncertain. We...

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...
