To survive winter, many perennial plants become endodormant, a state of suspended growth maintained even in favorable growing environments. To understand vegetative bud endodormancy, we collected paradormant, endodormant, and ecodormant axillary buds from Populus trees growing under natural conditions. Of 44,441 Populus gene models analyzed using NimbleGen microarrays, we found...

To examine whether stream nitrogen concentrations in forested reference catchments have
changed over time and if patterns were consistent across the USA, we synthesized up to 44 yr
of data collected from 22 catchments at seven USDA Forest Service Experimental Forests.
Trends in stream nitrogen presented high spatial variability both...

Neurospora crassa has been for decades a principal model for filamentous
fungal genetics and physiology as well as for understanding
the mechanism of circadian clocks. Eukaryotic fungal and animal
clocks comprise transcription-translation-based feedback loops that
control rhythmic transcription of a substantial fraction of these transcriptomes,
yielding the changes in protein...

Hybridization has been identified as a significant factor in the evolution of plants as groups of interbreeding species retain their phenotypic integrity despite gene exchange among forms. Recent studies have identified similar interactions in animals; however, the role of hybridization in the evolution of animals has been contested. Here we...

Stressors associated with human activities interact in complex ways to affect marine ecosystems,
yet we lack spatially explicit assessments of cumulative impacts on ecologically and
economically key components such as marine predators. Here we develop a metric of
cumulative utilization and impact (CUI) on marine predators by combining electronic tracking...

Atmospheric CO₂ records for the centennial scale cooling event 8200 years ago (8.2 ka event) may
help us understand climate-carbon cycle feedbacks under interglacial conditions, which are important for
understanding future climate, but existing records do not provide enough detail. Here we present a new CO₂
record from the Siple...

Trade in staple crop commodities has become increasingly important in the global food system, with ramifications for both food security and water resources sustainability. It is thus essential to understand how the water footprint (WF) of staple crop trade may change in the future. To this end, we project international...

Considerable uncertainties often surround the causes of long-term changes in population abundance. One striking example is the precipitous decline of southern sea lions (SSL; Otaria flavescens) at the Falkland Islands, from 80 555 pups in the mid 1930s to just 5506 pups in 1965. Despite an increase in SSL abundance over...
