Along the Benthic to Holoplanktonic Continuum: Seafloor Affinity Increases Distance‐Decay Rates Among Abyssal CommunitiesNARA Subscribed
Aim Marine species ranges are often large, contributing to relatively high community similarity over space, with decreased ranges expected among taxa that have lower dispersal and/or higher substrate requirements. We tested for a weakening of biogeographic structuring among dispersing abyssal taxa along the benthic to holoplanktonic habitat continuum by comparing geographic ranges and rates of community dissimilarity across th...
The hyperiid amphipod Brachyscelus rapacoides is a warm-water species associated with gelatinous zooplankton. In the Mediterranean it has been reported in association with Rhopilema nomadica in both Israel and Turkey. Here, we document the first record of B. rapacoides in Greek waters, representing the first confirmed record for Europe, based on both morphological examination and DNA barcoding of the mitochondrial COI gene. Sp...
Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries in the Southwest Indian Ocean (SWIO) region of Africa. Using the Elinor tool and dat...
Anadromous Arctic char ( Salvelinus alpinus ) and northern form Dolly Varden ( Salvelinus malma malma ) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for assessment of current and future impacts. The Coppermine River, Nunavut, provides a unique...
Deep-sea whale falls serve as biodiversity hotspots and pass through distinct successional stages, with the duration of the sulphophilic stage remaining controversial. We conducted a 15-year time-series study of a blue or fin whale skeleton on the edge of the Oxygen Minimum Zone at 1288 m depth on the Clayoquot Slope, Cascadia Continental Margin, using ROV surveys and high-resolution 3D photogrammetry to assess long-term ecosy...
Relative importance of climate versus socio-environmental development changes to 2050 in rural coastal Bangladesh—a system analysisNARA Subscribed
Climate change and development are having a profound influence on the integrity of coastal Bangladesh’s people, economy and ecology with climate change widely considered the dominant driver. Our bespoke integrated assessment model (IAM) simulates these changes for rural areas by coupling physical models with economic models, considering shocks like cyclone landfalls, and utilising substantial primary/secondary datasets and sta...
Aim Human activities have profoundly altered biodiversity and ecosystems worldwide, particularly impacting freshwater systems crucial for many reptile species, such as crocodilian and chelonian species, many of which rely heavily on freshwater habitats. Here, we assessed the influence of human‐altered variables (human footprint, aridity index, and livestock layers) and conservation lands on global crocodilian and chelonian spe...
The abyssal benthic boundary layer (BBL) community relies on pelagic organic matter (OM) export, yet community dynamics under changing surface productivity remain poorly understood. Here, we describe temporal variability within the BBL zooplankton community, focusing on benthopelagic adults and meroplanktonic larvae at a site with seasonal OM flux. We test the hypothesis that BBL community composition, richness, and structure...
Combined Evidence Reveals the Origin of a Rapid Range Expansion Despite Retained Genetic Diversity and a Weak Founder EffectNARA Subscribed
Many species are currently experiencing range shifts in response to changing environmental conditions with potentially serious genetic consequences. Repeated founder events and strong genetic drift are expected to erode genetic variation at the range front, reducing adaptive potential and slowing or even halting the expansion. However, the severity of these consequences for common and highly mobile species undergoing environme...
Cross‐Continental Analysis Shows That Disturbance Effects on Reptile Body Condition Do Not Predict Abundance ResponsesNARA Subscribed
Ecological disturbances are discrete events that alter or transform the physical, chemical, or biological characteristics of ecosystems. Disturbance can cause animal populations to decline and, according to the risk‐disturbance hypothesis and population collapse framework, these declines can be predicted by declines in animal body condition. However, no research has empirically examined the general relationship between body co...
Tundra Vegetation Community Type, Not Microclimate, Controls Asynchrony of Above‐ and Below‐Ground PhenologyNARA Subscribed
The below‐ground growing season often extends beyond the above‐ground growing season in tundra ecosystems and as the climate warms, shifts in growing seasons are expected. However, we do not yet know to what extent, when and where asynchrony in above‐ and below‐ground phenology occurs and whether variation is driven by local vegetation communities or spatial variation in microclimate. Here, we combined above‐ and below‐ground...
Post-stroke dysphagia (PSD) is common and associated with poor outcomes. We aimed to explore the feasibility, safety, and proof of concept of cerebellar rTMS in patients with sub-acute PSD. We intended to recruit 48 participants with PSD. Randomised to: (i) sham treatment twice-daily for five days, (ii) cerebellar rTMS daily for three days, and (iii) cerebellar rTMS twice-daily for five days (1:1:1). Participants were blinded...
Identification and epidemiological analysis of a putative novel hantavirus in Australian flying foxesNARA Subscribed
In July 2017, an investigation into the cause of neurological signs in a black flying fox ( Pteropus alecto , family Pteropodidae ) identified a putative novel hantavirus (Robina virus, ROBV, order Bunyavirales , family Hantaviridae , genus Mobatvirus ) in its brain. Analysis of the evolutionary relationship between other hantaviruses using maximum-likelihood, a systematic Bayesian clustering approach, and a minimum spanning t...
Estimates of disclosure and victimization rates for fishery observers in the maritime workplaceOA Marine
Seafarers working in remote ports and onboard fishing vessels often face isolated, high-risk environments, making them vulnerable to sexual harassment, intimidation, and assault. In the United States and other countries, scientists, called fishery observers, are required by the government to be deployed alongside fishing crews for extended periods to collect essential fisheries data and report potential fishing regulation viol...
