A striking case of convergent evolution in two species of Cypricercinae (Crustacea, Ostracoda), with the description of ...
Comparative vegetation survey with focus on cryptogamic covers in the high Arctic along two differing catenas
...
Although cryptogamic covers are important ecosystem engineers in high Arctic tundra, they were often neglected in vegetation surveys. Hence we conducted a systematic survey of cryptogamic cover and vascular plant coverage and composition at two representative, but differing Arctic sites (Ny-angstrom lesund, Svalbard) along catenas with a natural so...
Extreme drought periods can change spatial effects on periphytic ostracod metacommunities in river-floodplain ecosystems...
Published in Hydrobiologia
Hydrological regimes are seasonally variable in river-floodplain ecosystems. Thus, since in these environments the local and regional factors change at different temporal scales, factors structuring metacommunities might also differ over time. However, temporal dynamics of metacommunities have rarely been assessed. Here, we investigated the influen...
Association of polypharmacy and hyperpolypharmacy with frailty states: a systematic review and meta-analysis
...Published in European Geriatric Medicine
PurposeTo investigate: (1) the cross-sectional association between polypharmacy, hyperpolypharmacy and presence of prefrailty or frailty; (2) the risk of incident prefrailty or frailty in persons with polypharmacy, and vice versa.MethodsA systematic review and meta-analysis was performed according to PRISMA guidelines. We searched PubMed, Web of Sc...
Diatom β‐diversity in streams increases with spatial scale and decreases with nutrient enrichment across regional to sub...
To quantify the relative contributions of local community assembly processes versus γ‐diversity to β‐diversity, and to assess how spatial scale and anthropogenic disturbance (i.e. nutrient enrichment) interact to dictate which driver dominates. Location: France and the United States. Time period: 1993 - 2011. Major taxa studied: Freshwater stream d...
Quantifying leaf-trait covariation and its controls across climates and biomes.
Published in The New phytologist
Plant functional ecology requires the quantification of trait variation and its controls. Field measurements on 483 species at 48 sites across China were used to analyse variation in leaf traits, and assess their predictability. Principal components analysis (PCA) was used to characterize trait variation, redundancy analysis (RDA) to reveal climate...
Rate of forest recovery after fire exclusion on anthropogenic savannas in the Democratic Republic of Congo
Deforestation in the tropics is often followed by the creation of anthropogenic savannas used for animal husbandry. By discontinuing burning regimes, forests may recolonize the savanna and carbon stocks may recover. However, little is known about the success and speed of tropical forest recovery, while such information is vital for a better quantif...
Drought intensification alters the composition, body size, and trophic structure of invertebrate assemblages in a stream...
...
Predicted trends towards more intense droughts are of particular significance for running water ecosystems, as the loss of critical stream habitat can provoke sudden changes in biodiversity and shifts in community structure. However, analysing ecological responses to the progressive loss of stream habitat requires a continuous disturbance gradient ...
Improving moderator responsiveness in online peer support through automated triage
Background: Online peer support forums require oversight to ensure they remain safe and therapeutic. As online communities grow, they place a greater burden on their human moderators, which increases the likelihood that people at risk may be overlooked. This study evaluated the potential for machine learning to assist online peer support by directi...
Change in dominance determines herbivore effects on plant biodiversity
...Published in Nature Ecology & Evolution
Evidence synthesized from 252 large-herbivore exclusion studies suggests that herbivore-induced change in dominance, independent of site productivity or precipitation, best predicts herbivore effects on biodiversity in grassland and savannah sites.
