Seasonality and energetic impacts of castrating parasites on an estuarine mud crab along a salinity gradientNARA Subscribed
Estuaries exhibit pronounced fluctuations in the abiotic environment, and salinity strongly structures species distribution, physiology, and biotic interactions, including hosts and their parasites. The white-fingered mud crab Rhithropanopeus harrisii is host to two macroparasites: the invasive rhizocephalan barnacle Loxothylacus panopaei and a recently described entoniscid isopod Cryptocancrion brevibrachium . To investigate...
Salinity is a critical factor determining the impact and establishment of aquatic invasive species. We quantified the functional responses and prey consumption rates of the invasive mud crab Rhithropanopeus harrisii across a salinity gradient to evaluate how low salinity stress influences foraging in the northern Baltic Sea, and found significant differences in both attack rate ( a ) and handling time ( h ) across salinity tre...
Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservationNARA Subscribed
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time. Sharks, rays, and chimaeras (Chondrichthyes) have now been comprehensively assessed twice (1996–2011 and 2012–2021) with hindcast assessments from 1970 onward, yielding an unprece...
Caribbean Creep meets Chesapeake Creep: marine bioinvasions and community shifts along the Mid-Atlantic Coast, USANARA Subscribed
The Mid-Atlantic waters of North America are warming faster than > 90% of other global oceans, leading to significant increases in bottom water temperatures and influencing shifts in marine community structure. Given this modern-day scenario of significant community shifts over space and time, baseline surveys of species diversity are increasingly valuable. Therefore, we performed the first-ever marine bioinvasions Rapid Asses...
Along the U.S. east coast, the widespread non-native red alga Gracilaria vermiculophylla provides habitat for an array of macroinvertebrates, including the eastern mudsnail Ilyanassa obsoleta . Though I. obsoleta tolerates a wide temperature range, increases in summer water temperatures may enhance mortality; furthermore, the presence of non-native algae in rising seawater temperatures could exacerbate harmful conditions. We t...
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α‐diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased β‐diversity dampening diversity loss. Additionally, studies often focus on taxo...
Shortcutting Photorespiration Protects Potato Photosynthesis and Tuber Yield Against Heatwave StressNARA Subscribed
Over two growing seasons, a chloroplast localized synthetic glycolate metabolic pathway expressed in potato, enhanced tuber biomass. We confirmed that this yield benefit did not come at the cost of tuber quality. In 2022, after two early season natural heatwaves, we observed enhanced daily carbon assimilation rates and increased photosynthetic capacity, with transformed plants having up to 23% higher V cmax and 13% higher J ma...
Toward sustainable harvest strategies for marine fisheries that include recreational fishingNARA Subscribed
Recreational fishing (RF) is a large yet undervalued component of fisheries globally. While progress has been made in monitoring, assessing, and managing the sector in isolation, integration of RF into the management of multi‐sector fisheries has been limited, particularly relative to the commercial sector. This marginalises recreational fishers and reduces the likelihood of achieving the sector's objectives and, more broadly,...
Multi-criteria analysis for rapid vulnerability assessment of marine species to climate changeNARA Subscribed
The accelerating pace of climate-induced stress to global ecosystems threatens the sustainable management and conservation of biodiversity. To effectively respond, researchers and managers require rapid vulnerability assessment tools that can be readily implemented using diverse and existing knowledge sources. Here we demonstrate the application of multi-criteria analysis (MCA) for this purpose using a group of coastal-pelagic...
