Less cooperative belowground plant mutualists negatively affect aboveground herbivore growth and survivalNARA Subscribed
Resource mutualists like nitrogen (N)-fixing rhizobia can improve the quality of plants available to higher trophic levels, particularly primary consumers like insect herbivores. However, there is substantial variation in mutualist quality. How this variation in mutualist quality affects higher trophic levels, such as herbivores, is unclear, as high-quality resource mutualists could increase both leaf nutrient content, which s...
Alterations of cryptogam communities over one decade of time on King George Island, AntarcticaNARA Subscribed
Antarctica’s ice-free areas are mainly colonized by cryptogamic communities, which are known to be sensitive indicators of environmental change. Despite numerous monitoring-related studies, published research on medium-term cryptogam cover changes is limited. With this study, we aimed to investigate compositional and structural changes in cryptogamic communities over a decade near the Polish Arctowski Antarctic Station. Here,...
Assessing shortnose sturgeon response to estuarine dredging in the Savannah River using a before-after control-impact (BACI) approachNARA Subscribed
Estuaries are productive ecosystems that support diverse aquatic species and human economies through fisheries, recreation, and navigation. However, coastal development and dredging have altered the ecological processes of estuarine habitats. In the Savannah River estuary, the Savannah Harbor Expansion Project (SHEP) deepened the river’s navigational channel by dredging to amplify vessel commerce. The endangered shortnose stur...
Assessing differences among elasmobranch nurseries to aid conservation based on a genomics frameworkNARA Subscribed
Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize. We assessed differences in connectivity, genetic variation, and numbers of breeders among scalloped hammerheads ( Sphy...
Mineral Stabilization Slows Losses of Peatland Carbon Following Long‐Term Drainage for AgricultureNARA Subscribed
Cultivated peatlands are a major CO 2 emission source, but the processes that regulate the decomposition of drained peat are debated, especially as drained peat becomes increasingly shallow. Many cultivated peatlands are underlain by a mineral soil layer. Surface subsidence, oxidation and tillage reduce the peat thickness, which intermixes peat with minerals as peat is lost. A key question is whether this mixing can reduce emi...
Mite domatia — small structures on plant leaves that house mutualistic mites — are widespread across plants yet remain relatively understudied. Here we investigate the chemistry and micromorphology of mite domatia across sympatric species of broadleaf deciduous woody species that have convergently evolved tuft-form mite domatia. Specifically, we test whether domatia display similar micromorphological and chemical properties us...
Monitoring evapotranspiration to link agricultural water use with crop yield at sub-field scalesNARA Subscribed
Purpose Scientists and producers have pursued precision agriculture to increase yields and limit environmental impacts. Applying precision agriculture concepts has not been straightforward, however, because complex interactions between soil and weather govern crop growth. We hypothesize that evapotranspiration (ET) is a single metric that captures interactions between plant status, soil, topography, and weather and can be used...
