The non-native larval parasitoid wasps Leptopilina japonica and Ganaspis kimorum (Hymenoptera: Figitidae), which attack larvae of the invasive pest Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), were unintentionally introduced to the Pacific Northwest of North America between 10 and 15 years ago, and are now well established. Previous laboratory studies conducted to assess the ecological risk of classical biological...
eRNA Reveals Real‐Time Signals of Freshwater Fish Population Biomass and Total AbundanceNARA Subscribed
Biomass and abundance data are critical for ecosystem monitoring and management of fish populations, yet their acquisition represents a growing challenge as anthropogenic pressures intensify the need for monitoring. Environmental DNA (eDNA) has the potential to provide cost‐effective biomass and abundance estimations, but its high molecular stability makes it prone to false positives. By contrast, environmental RNA (eRNA) has...
The Atlantic meridional overturning circulation (AMOC) is expected to decline dramatically over the 21st century, with severe impacts for Northern Hemisphere climate. After 20 years of sustained monitoring in the subtropics, a detectable AMOC weakening trend is now beginning to emerge. However, continuous observations at subpolar latitudes are currently too short-lived to determine any weakening signal above the large-amplitud...
Shortleaf Pine (Pinus echinata): Management Challenges, Knowledge Gaps, and Opportunities for an Unsung SpeciesNARA Subscribed
Shortleaf pine has the broadest range of the southern pine species, occurring in 22 states and extending north into New Jersey, Pennsylvania, and New York (Staten Island). Shortleaf pine has been understudied compared to loblolly pine and longleaf pine, typically favored for timber production and conservation value, respectively. The extensive range of shortleaf pine contributes to a high degree of variability within and among...
A giraffe nicknamed Marius attracted international media attention and world-wide notoriety when euthanized by Copenhagen Zoo in 2014, deemed surplus to the European breeding program. This incident highlights the challenges of managing zoo populations to best contribute to species conservation amid limited resources. Here, we investigated the degree of admixture, genetic diversity and inbreeding in ex situ giraffes using whole...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
The Rockall Trough, northwest of Scotland and Ireland, is a key conduit for the North Atlantic Current (NAC) and European Slope Current (ESC) transporting heat and salt toward the Nordic Seas and Arctic Ocean while mediating exchanges between the open ocean and the European shelf. We present a decade-long record of Rockall Trough circulation from the Ellett Array providing the first continuous estimates of heat and freshwater...
The transition from a free‐living lifestyle to endosymbiosis represents a large evolutionary shift, impacting various aspects of any organism's biology, including its molecular‐genetic groundwork. So far, it has been impossible to generalise the impact this lifestyle shift has on genomic architecture. This study explores this phenomenon using a new model system: neodalyellid flatworms (Rhabdocoela), a diverse assemblage of fre...
The Atlantic meridional overturning circulation (AMOC) has a notable seasonal component. This influences the jet stream and the location, frequency, and intensity of extreme weather events. Understanding this seasonality is important for mitigating the impacts of AMOC changes on European weather and climate. Here, we place meridional overturning and fluxes in a coherent framework. This framework highlights the integral relatio...
