Collection, handling and care of cephalopod eggsNARA Subscribed
Research on cephalopod early ontogeny has significantly advanced in recent decades, including embryo organogenesis and neurogenesis and early behavioural adaptations, particularly in commercially important and coastal species. Within this context, here we compiled current knowledge on the collection, handling and care under experimental conditions and monitoring in the field of cephalopod eggs and egg masses. It covers field o...
The presence of frailty is common in people with Parkinson’s disease (PD), as is cognitive dysfunction. Frailty is a dynamic process that can be reversed, so early detection is essential. The objective of this study is to evaluate the feasibility and safety of a home-based physical therapy program for frail patients with idiopathic Parkinson’s disease and cognitive impairment. An exploratory, pilot, randomized, single-blind ex...
Characterizing the genetic structure and connectivity between populations of endangered species can be used to inform management actions. In vagile species with high gene flow or recently established populations, such characterizations can be difficult to undertake using traditional genetic markers, and genetic stock identification (GSI) may be confounded by allele-sharing between populations. Loggerhead sea turtles ( Caretta...
Aim Mountain roads host plant communities that differ strongly from the adjacent natural vegetation. Besides the effect of propagule pressure, altered disturbance and soil processes, one of the reasons given for the strong influence of mountain roads on species distributions is a significantly altered soil thermal microclimate in the roadside compared to the adjacent vegetation, as a direct consequence of road disturbance. How...
Controls on Seasonal Atmosphere‐Ecosystem Carbon Dioxide Exchanges in a Temperate Salt MarshNARA Subscribed
Salt marshes play a vital role in the biogeochemistry of coastal zones, yet the biophysical controls on CO 2 exchange with the atmosphere, or net ecosystem exchange (NEE, positive upwards) remain poorly quantified. We investigated a Spartina alterniflora monoculture salt marsh on the eastern shore of Virginia, United States, by estimating half‐hourly NEE from March 2016 to February 2017 using the eddy‐covariance method. Maximu...
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...
A fundamental trade‐off among resilience, resistance, efficiency, and redundancy in tidal wetlandsNARA Subscribed
In an era of change, the survival and adaptability of ecosystems will be tested. An optimal ecosystem would be both resistant and resilient to negative disturbance but also efficient and redundant in its growth when given positive subsidies. However, initial evidence has suggested that these properties cannot all be maximized at the same time, and so we sought to quantitatively assess whether there are fundamental trade‐offs b...
