Seasonal genotypic and phenotypic differentiation of a cosmopolitan freshwater diatomNARA Subscribed
Most ecosystems are characterized by seasonality, which, through biotic and abiotic changes, influences species biomass dynamics. Recent studies have shown that ecologically important traits can evolve rapidly in response to environmental changes, resulting in eco‐evolutionary dynamics with consequences for population and community dynamics. Evidence for seasonal effects on intraspecific variation is still scarce and understan...
A sequence of weather‐driven hydrodynamic events stimulates the formation of harmful algal blooms on an oligotrophic lakeNARA Subscribed
Harmful algal blooms (HABs) are common in many eutrophic lakes and frequently associated with nutrient excesses, warm waters, and calm conditions. While HABs can also occur in oligotrophic waterbodies, bloom‐stimulating factors remain elusive for these ecosystems. Here, using a high‐frequency sensor platform supported by hydrodynamic modeling, we document a clearly linked sequence of three hydrodynamic events that immediately...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Summary Ruminococcus bromii is a dominant member of the human colonic microbiota that plays a ‘keystone’ role in degrading dietary resistant starch. Recent evidence from one strain has uncovered a unique cell surface ‘amylosome’ complex that organizes starch‐degrading enzymes. New genome analysis presented here reveals further features of this complex and shows remarkable conservation of amylosome components between human colo...

Phylogeography of the pitviper clade Agkistrodon : historical ecology, species status, and conservation of cantilsNARA Subscribed
We used mitochondrial DNA sequences from three gene regions and two tRNAs (ND4, tRNA‐HIS‐SER, 12S, and 16S rDNA) to investigate the historical ecology of the New World pitviper clade Agkistrodon , with emphasis on the disjunct subspecies of the cantil, A. bilineatus . We found strong evidence that the copperhead ( A. contortrix ) is basal to its congeners, and that the cottonmouth ( A. piscivorus ) is basal to cantils. Phyloge...
