High temperatures reduce growth, infection, and transmission of a naturally occurring fungal plant pathogenNARA Subscribed
Climate change is rapidly altering the distribution of suitable habitats for many species as well as their pathogenic microbes. For many pathogens, including vector‐borne diseases of humans and agricultural pathogens, climate change is expected to increase transmission and lead to pathogen range expansions. However, if pathogens have a lower heat tolerance than their host, increased warming could generate so‐called thermal ref...
Seagrasses are marine flowering plants distributed worldwide. They are however threatened, mostly due to the increase of human activities. Seagrasses have the capacity to adapt their morphological, physiological, and mechanical traits to their local conditions. Mechanical traits have been identified as a good tool to investigate a plant‐species capacity to withstand physical forces or disturbances but are still sparsely studie...
Mapping the role of tropical cyclones on the hydroclimate of the southeast United States: 2002–2011NARA Subscribed
The role of tropical cyclones ( TCs ) in the water budget of 3211 watersheds in the southeast United States ( SE US ) over the last decade (2002–2011) is examined in detail at daily and longer time‐scales towards mapping regional hydro‐climatic vulnerabilities. The work documents highly heterogeneous spatial and inter‐annual patterns of variability in the contribution of TC events to the annual cycle of rainfall from below 5%...
The nuclear ribosomal internal transcribed spacer ( ITS ) region is the formal fungal barcode and in most cases the marker of choice for the exploration of fungal diversity in environmental samples. Two problems are particularly acute in the pursuit of satisfactory taxonomic assignment of newly generated ITS sequences: (i) the lack of an inclusive, reliable public reference data set and (ii) the lack of means to refer to funga...
Serpentine and non‐serpentine ecotypes of Collinsia sparsiflora associate with distinct arbuscular mycorrhizal fungal assemblagesNARA Subscribed
Although plant adaptation to serpentine soils has been studied for several decades, the mechanisms of plant adaptation to edaphic extremes are still poorly understood. Arbuscular mycorrhizal fungi (AMF) are common root symbionts that can increase the plant hosts’ establishment and growth in stressful environments. However, little is known about the role plant–AMF interactions play in plant adaptation to serpentine. As a first...
Interaction between hydrodynamics and seagrass canopy structure: Spatially explicit effects on ammonium uptake ratesNARA Subscribed
The hypotheses that (1) different seagrass morphologies may facilitate different nutrient uptake rates under similar hydrodynamic forcing and (2) this effect on nutrient uptake rates is spatially explicit, with the highest uptake rates at edges of patches, where currents and turbulence are highest, were examined under unidirectional flow conditions. Homogeneous patches (2 m long) of two seagrass species ( Cymodocea nodosa and...
