Introduction Arctic warming has resulted in substantial decreases in sea ice and a longer open-water season. This is occurring concurrently with changes in Bering-Chukchi-Beaufort bowhead whale seasonal movements and increasing vessel traffic through Bering Strait, which may increase strike risk. Methods To assess vessel traffic relative to bowhead whale distributions before (2013/14–2016/17), during (2017/18), and after (2018...
Accurate prediction of community assembly is a central goal in ecology but is challenging because assembly is governed by numerous mechanisms. Few theoretical models explicitly incorporate or test multiple mechanisms at once. We empirically tested the predictive performance of a plant community assembly model built using all possible combinations of four ‘mechanisms’ (soil resource competition, dispersal and colonisation, spat...
Despite a broad consensus on the necessity of fundamental change, endeavors to transform food systems appear to have reached an impasse. Greater engagement with the uncertainty of food systems could open up new ways of triggering transformation directed towards achieving more sustainable and inclusive outcomes. As a way of reorienting current food system change efforts to better embrace uncertainty, we propose a framework for...
Macrofauna accelerates nutrient cycling through litterfall in cocoa agroforestry systemsNARA Subscribed
This study aimed to better understand nitrogen (N), phosphorus (P), and potassium (K) cycling through litterfall in smallholder cocoa agroforestry systems and to assess if these nutrient flows can be measured using standard litterbags. Annual litter production, relative mass loss, and nutrient loss rates from cocoa leaf litter were evaluated in three farms in south-western Nigeria with and without macrofauna access. Litterfall...
Differential effects of fentanyl compared to morphine on neuroinflammatory signaling in the brain in EcoHIV-infected miceNARA Subscribed
HIV-associated neurocognitive disorders (HAND) pose significant challenges, particularly in individuals with comorbid opioid use disorder (OUD). Fentanyl, a potent synthetic opioid, is a leading contributor to opioid-related fatalities, yet its effects in the context of HIV remain poorly understood. This study investigated the differential impacts of fentanyl and morphine on neuroinflammatory signaling, blood–brain barrier (BB...
Microstructure development in lacustrine, fine-grained sediments traced by in situ and laboratory testingNARA Subscribed
Soil microstructure, often defined as the combination of particle arrangement and bonding, can strongly influence the stiffness and strength of sedimentary deposits. As undisturbed soil sampling is a challenging task in fine-grained soils, seismic in situ testing is becoming increasingly more important to investigate its mechanical behaviour. The aim of this article is to evaluate the influences of sediment depositional age an...
Since 1950, coral abundance has declined worldwide by an estimated 60%, and further dramatic declines are predicted. Although global reductions in carbon emissions are essential to prevent further loss, coral reef restoration has become imperative to maintain the ecosystem services that coral reefs provide to humans at local scales. Yet, currently coral restoration and gardening efforts are too expensive to scale up due to the...
