Tropical rivers are major contributors to global carbon cycling, yet the microbial communities driving these transformations remain largely uncharacterized. We investigated bacterioplankton communities along the northwest Congo watershed using 16S rRNA and metagenomic sequencing, paired with hydrological, biogeochemical, and greenhouse gas data. In large rivers, community composition correlated with temperature and water trave...

In estuaries where native eelgrass ( Zostera marina ) and Pacific oyster ( Magallana gigas ) aquaculture co-occur along the US Pacific Coast, contemporary landscape-scale distributions are essential to properly assess the interaction between these habitats and balance priorities of eelgrass conservation and sustainable aquaculture. We classified eelgrass distribution and delineated active oyster aquaculture throughout Willapa...

Low-dose applications of certain herbicides have been hypothesized to induce physiological responses that conserve water and reduce aflatoxin contamination risk in peanut ( Arachis hypogaea L.). Motivated by reported leaf rolling following diflufenzopyr application, this study evaluated whether herbicide-induced stomatal closure and biomechanical changes could serve as a water-saving mechanism during late-season stress. Farm f...

The house sparrow ( Passer domesticus ) is one of the most widespread invasive bird species, with numerous and dense populations established across urban-agricultural landscapes of North America. Although this species has been widely studied to identify the traits that explain its global ubiquity, descriptions of house sparrow acoustic features across its native and introduced range are limited in the literature. We recorded m...

Species persist through resistance and recovery traits induced by natural stressors. Whether human activities exacerbate or moderate the effects of natural stressors is an open question. Because eelgrass ( Zostera marina ) creates coastal habitat, its response to natural stressors and human activities is of particular management importance. In this study, traits of intertidal eelgrass were examined across cumulative stressors...

Key message Low-lodging high-yielding wheat germplasm and SNP-tagged novel alleles for lodging were identified in a process that involved selecting donors through functional phenotyping for underlying traits with a designed phenotypic screen, and a crossing strategy involving multiple-donor × elite populations. Abstract Lodging is a barrier to achieving high yield in wheat. As part of a study investigating the potential to bre...

Extinction rates are expected to increase during the Anthropocene. Current extinction rates of plants and many animals remain unknown. We quantified extinctions among the vascular flora of the continental United States and Canada since European settlement. We compiled data on apparently extinct species by querying plant conservation databases, searching the literature, and vetting the resulting list with botanical experts. Bec...
