We have attempted to re-establish bay scallops to the Virginia, U.S.A. coastal bays and document the dynamics of the restoration effort. Bay scallops ( Argopecten irradians ) once flourished in the eelgrass ( Zostera marina ) of the Virginia coastal bays. Eelgrass wasting disease led to declines, and both eelgrass and scallops were completely lost after a 1933 hurricane. The Virginia Institute of Marine Science (VIMS) led a su...
In July 2022, a harmful algal bloom of Heterosigma akashiwo originated in a man-made lagoon and expanded to more than 4,500 km² of open-water habitat in the San Francisco Estuary, triggering a widespread mass mortality event involving bony fishes, sharks, rays, crustaceans, mollusks, polychaetes, and jellyfish. Notably, the event affected the southernmost spawning populations of White Sturgeon ( Acipenser transmontanus ) and f...
Divergent Selection on Dispersal Targets Chemosensory and Neuronal Genes in Tribolium castaneumNARA Subscribed
Dispersal is key to the life history, ecology and evolution of many organisms and important in pest invasiveness. However, the genetic architecture underlying variation in dispersal behaviour remains poorly understood outside of a few model species. We investigated the genomic basis of dispersal using artificial selection on replicated lines of Tribolium castaneum , a flour beetle, an emergent model system and an economically...
Success of restoration strategies in preventing extirpation of 2 critically endangered coral speciesNARA Subscribed
An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral ( Acropora palmata ) and staghorn coral ( Acropora cervicornis ), were severely affected. These species have been the primary focus of reef restoration in Florida for decades. Substantial losses of these species occurred in outplanted populations, in o...
Dehydrating microhabitats increase mite activity and intensify ectoparasitism of DrosophilaNARA Subscribed
Parasites interact with their host in variable environments that are often subject to water scarcity and dehydration. Drosophilid fruit flies and associated ectoparasitic mites interact across a range of microhabitats, typically in decaying organic matter, such as fallen fruit and cactus tissue, that dries out and deteriorates over periods ranging from days to months. Here, we report that mite parasitism of Drosophila increase...
QTL mapping of oat crown rust resistance in Australian fields and identification of a seedling resistance locus in oat line GS7NARA Subscribed
The development of oat cultivars with resistance to crown rust caused by Puccinia coronata f. sp. A venae ( Pca ) is key for sustainable disease control. This study examined two recombinant inbred line populations, Provena x GS7 and Boyer x GS7, to identify adult plant resistance QTL in Australian fields. Seven distinct QTL associated with rust resistance were identified. KASP markers were developed for single nucleotide polym...
