To maintain diverse communities under changing environmental conditions, species must be able to concentrate density feedback within species compared to between species. Density feedback can occur via multiple mechanisms, including predator partitioning, and is often mediated by the physical environment. If species respond differently to the environment (e.g. susceptibility to predators changes under different conditions) then...
Perinatal exposure to delta-9-tetrahydrocannabinol (THC) alters goal-directed behavior and dopamine functioning in wistar ratsNARA Subscribed
Rationale Cannabis use during 2021pregnancy is common as many pregnant women consider cannabis as a safe way to alleviate symptoms associated with pregnancy because it is “natural”. However, clinical evidence links perinatal cannabis exposure to externalizing behavior in offspring. In preclinical research, most studies focus on exposure to the psychoactive constituent of cannabis, delta-9-tetrahydrocannabinol (THC). THC is lip...
The proportion of individuals that are found to have empty stomachs during a survey of a predator population's diet has been used as an indicator of the average individual's state of energy balance and of the degree to which its feeding rate (i.e., its functional response) is saturated with respect to prey availability. As such, the proportion of empty stomachs provides insights into the effects of prey on predators and vice v...
Streptococcus dysgalactiae From Farm‐Raised Channel Catfish in Mississippi, USA, With Notes on Fish‐Associated Group C S. dysgalactiaeNARA Subscribed
Lancefield serological group C Streptococcus dysgalactiae (GCSD) is an emerging cause of fish disease worldwide, largely associated with mariculture in Asia. In the United States (US), GCSD had been a pathogen of minimal concern for fish, but recent cases indicate a putative emergence in wild and cultured freshwater fish populations in the Americas. The current study discusses three novel cases of GCSD‐associated streptococcos...
Insights on the roles of women in effective and procedurally just environmental governance from coastal fisheries management in FijiNARA Subscribed
Conservationists and fisheries managers have historically focused somewhat narrowly on achieving environmental goals at the expense of environmental justice. We examined the links between the two in the context of coastal fisheries management in Fiji, a nation highly dependent on marine resources and with significant external conservation investment. We focused on procedural justice, an underexamined dimension of environmental...
Mariculture Narratives in Climate Change Research and Policy: Alignment, Mismatch, and Opportunities for a Climate‐Resilient IndustryNARA Subscribed
Like other sectors of our global food system, marine aquaculture (mariculture) is threatened by a myriad of stressors resulting from a changing climate. Increasing attention has been given to the impact of these stressors on mariculture across a variety of taxonomies and geographies. Alongside this perspective of mariculture as vulnerable to climate change impacts, another narrative has also emerged framing mariculture as a po...
Small-scale fisheries provide seafood for billions of people and are one of the largest employers in many coastal communities. Those households engaged in these fisheries who maintain diverse income sources are generally thought to be better prepared to cope with social or ecological perturbations such as the crises presented by the COVID-19 pandemic. One outcome of the COVID-19 crisis was the collapse of international tourism...
Plant stable carbon (δ 13 C) and nitrogen (δ 15 N) isotope values can be used to directly investigate crop husbandry practices such as manuring; a key variable in understanding the scale and intensity of past farming practices. We present new results from a four-year experiment examining the impact of manuring on the δ 13 C and δ 15 N values of a heritage cultivar of the broad or faba bean ( Vicia faba ), the ‘Celtic black bro...
Ultrasound imaging can be used as an effective tool to measure the reproductive status and condition of sharks. This usually requires restraint of the subject, which is not feasible in the wild when the target species is of conservation concern and very large, as is the case for whale sharks. Our study invoked a behavioral response in free-swimming whale sharks that allowed snorkelers to image internal organs and structures us...
