Purpose Sediment removal can reduce internal phosphorus loading in eutrophic lakes, yet extracted sediment is often treated as waste and its disposal represents a major remediation cost. Repurposing dredged material as plant growth medium provides a circular pathway, but the suitability of brackish sediments is poorly resolved. We tested the ability of biochar to alleviate compaction and salinity-sodicity of brackish dredged s...
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...
Mechanisms underpinning community stability along a latitudinal gradient: Insights from a niche‐based approachNARA Subscribed
At large scales, the mechanisms underpinning stability in natural communities may vary in importance due to changes in species composition, mean abundance, and species richness. Here we link species characteristics (niche positions) and community characteristics (richness and abundance) to evaluate the importance of stability mechanisms in 156 butterfly communities monitored across three European countries and spanning five bi...
Aim It is important to understand the factors affecting community stability because ecosystem function is increasingly at risk from biodiversity loss. Here, we evaluate how a key factor, the position of local environmental conditions within the thermal range of the species, influences the stability of butterfly communities at a continental scale. Location Spain, UK and Finland. Time period 1999–2017. Major taxa studied Butterf...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Experimental evidence for ecological cascades following threatened mammal reintroductionNARA Subscribed
Species extinction has reached unprecedented rates globally, and can cause unexpected ecological cascades. Since Europeans arrived in Australia, many endemic mammals have declined or become extinct, but their ecological roles and outcomes of their reintroduction for ecosystems are poorly understood. Using surveys and novel long‐term exclusion and disturbance experiments, we tested how digging mammal reintroduction affects pred...
Troubled waters: Threats and extinction risk of the sharks, rays and chimaeras of the Arabian Sea and adjacent watersNARA Subscribed
The extinction risk of sharks, rays and chimaeras is higher than that for most other vertebrates due to low intrinsic population growth rates of many species and the fishing intensity they face. The Arabian Sea and adjacent waters border some of the most important chondrichthyan fishing and trading nations globally, yet there has been no previous attempt to assess the conservation status of species occurring here. Using IUCN R...
