Improving the Prediction of Treefrog Species Vulnerability to Climate Change: The Role of AbundanceNARA Subscribed
Aim As climate changes intensify over time due to anthropogenic pressures, it is estimated that a global shift in the current biodiversity patterns, including the loss of several species. Amphibians are the most threatened group by climate change and, in addition to distribution shifts, declines in species abundances are also expected. A widely used tool in biodiversity studies for measuring and predicting species' responses t...
Influence of herd and environmental factors and phenotypic trends in productive and reproductive traits in dairy farms in ArgentinaNARA Subscribed
Argentina hosts a wide range of dairy production systems, from pasture-based to confined models. Despite this diversity, genetic improvement has relied almost exclusively on imported semen from high-merit Holstein bulls. Unregistered Holstein populations managed under pasture-based systems account for a substantial share of national milk production, yet their productive and reproductive performance remains poorly documented. T...
Physiological and Proteomic Shifts in Pfaffia glomerata Under Drought and Elevated CO₂NARA Subscribed
Drought is a major constraint to plant growth and productivity, and rising atmospheric CO₂ concentrations are expected to modify plant responses to water limitation. However, how CO₂ enrichment reshapes the physiological, metabolic, and molecular regulation of specialized metabolite production under drought remains poorly understood. Here, we investigated the combined effects of elevated CO₂ (e[CO₂]) and drought on plant morph...
Beyond Climate Change: The Role of Integrated Soil Fertility Management for Sustaining Future Maize Yield in Sub‐Saharan AfricaNARA Subscribed
Climate change is projected to exacerbate food insecurity in sub‐Saharan Africa (SSA) by reducing crop yields and soil fertility. Many climate change impact studies in SSA have overlooked long‐term effects of soil fertility on crop yield. We evaluated maize yields under different scenarios of soil fertility (using soil organic carbon as a proxy) and climate change (considering changes in temperature, rainfall, and CO 2 ) at fo...
Assessing the effectiveness of toe buttressing on slope stability through monitoring and numerical modelling in a quarry in GermanyNARA Subscribed
Slope instability poses significant challenges in geotechnical engineering, necessitating effective mitigation strategies. Among these strategies, toe buttressing has emerged as a prominent method, involving the strategic placement of materials at the base of unstable slopes. However, the efficacy of toe buttressing remains insufficiently explored in scientific literature, particularly through the integration of real-time moni...
Food web complexity alters phytoplankton persistence and resilience to nutrient pulses in experimental ecosystemsNARA Subscribed
In aquatic ecosystems, greater food web complexity is theorized to increase persistence and resilience of primary production to pulse disturbances, yet experimental evidence is limited. We simulated two storm‐induced pulse disturbances by adding nutrients (~ 3%–5% increase in ambient concentrations) to three ponds with low, intermediate, and high food web complexity and compared to reference ponds. We evaluated the ecological...
Influencing Aquatic Invasive Species Prevention Behaviors: An Exploration and Experiment with Augmented RealityNARA Subscribed
Despite significant resource allocations to thwart invasive species introduction and spread, they remain a significant issue for environments and economies alike. Aquatic invasive species (AIS) are of particular interest given the value of water within and across societies. AIS prevention activities typically include outreach and education campaigns reliant on static signage which leave opportunities for greater engagement. Ad...
Atlantic-wide connectivity of Ascension Island green turtles revealed by finer-scale mitochondrial DNA markersNARA Subscribed
Marine turtles undertake long migrations across different geographies and habitats, exposing them to a wide range of threats throughout their lifespan. Analysing population structure and connectivity is key to informing effective conservation management. We expand knowledge of Atlantic-wide connectivity of green turtles ( Chelonia mydas ) by characterising the genetic structure of the Ascension Island nesting population, one o...
