Taylor’s frozen turbulence hypothesis is the central assumption invoked in most
experiments designed to investigate turbulence physics with time resolving sensors. It is also
frequently used in theoretical discussions when linking Lagrangian to Eulerian flow formalisms.
In this work we seek to quantify the effectiveness of Taylor’s hypothesis on the...
The process of plant speciation often involves the evolution of divergent ecotypes in
response to differences in soil water availability between habitats. While the same set of traits
is frequently associated with xeric/mesic ecotype divergence, it is unknown whether those
traits evolve independently or if they evolve in tandem as...
Next-generation DNA sequencing (NGS) approaches are rapidly surpassing Sanger sequencing for characterizing the diversity of
natural microbial communities. Despite this rapid transition, few comparisons exist between Sanger sequences and the generally
much shorter reads of NGS. Operational taxonomic units (OTUs) derived from full-length (Sanger sequencing) and pyrotag (454
sequencing of...
In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean acidification, with potentially wideranging biological effects. Population-level shifts are occurring because of physiological intolerance to new environments, altered dispersal patterns, and changes in species interactions. Together...
It is well established that individual organisms can acclimate and adapt to temperature to optimize their functioning. However, thermal optimization of ecosystems, as an assemblage of organisms, has not been examined at broad spatial and temporal scales. Here, we compiled data from 169 globally distributed sites of eddy covariance and...
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...

Benefits humans rely on from the ocean - marine ecosystem services - are increasingly vulnerable under future climate. This paper reviews how three valued services have, and will continue to, shift under climate change: (1) capture fisheries, (2) food from aquaculture, and (3) protection from coastal hazards such as storms...
