Environmental Variability Shapes Life‐History Trade‐Offs Within and Between Populations of a Long‐Lived SeabirdNARA Subscribed
Individuals face a trade‐off between allocating resources to reproduction or self‐maintenance, yet the drivers of the existence and strength of such trade‐off have been hard to determine. Environmental conditions are thought to play a crucial role, as long‐lived species are predicted to favour more precautionary life‐history strategies in variable environments. However, empirical evidence remains limited. Using long‐term monit...
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α‐diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased β‐diversity dampening diversity loss. Additionally, studies often focus on taxo...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Environmental factors influencing fine-scale distribution of Antarctica’s only endemic insectNARA Subscribed
Species distributions are dependent on interactions with abiotic and biotic factors in the environment. Abiotic factors like temperature, moisture, and soil nutrients, along with biotic interactions within and between species, can all have strong influences on spatial distributions of plants and animals. Terrestrial Antarctic habitats are relatively simple and thus good systems to study ecological factors that drive species di...

Variation in plant diversity in mediterranean‐climate ecosystems: the role of climatic and topographical stabilityNARA Subscribed
Aim Although all five of the major mediterranean‐climate ecosystems ( MCE s) of the world are recognized as loci of high plant species diversity and endemism, they show considerable variation in regional‐scale richness. Here, we assess the role of stable Pleistocene climate and Cenozoic topography in explaining variation in regional richness of the globe's MCE s. We hypothesize that older, more climatically stable MCE s would...
Aim The sub‐escarpment coastal plains of South Africa provide remarkable opportunities to study the determinants of biome boundaries as numerous biomes are found closely juxtaposed, including the Nama‐Karoo semi‐desert shrubland and Albany subtropical thicket. The Nama‐Karoo shrubland is centred on the semi‐arid and frosty high‐elevation interior plateau of South Africa, whereas the Albany subtropical thicket inhabits the comp...
Species richness declines and biotic homogenisation have slowed down for NW ‐European pollinators and plantsNARA Subscribed
Concern about biodiversity loss has led to increased public investment in conservation. Whereas there is a widespread perception that such initiatives have been unsuccessful, there are few quantitative tests of this perception. Here, we evaluate whether rates of biodiversity change have altered in recent decades in three European countries (Great Britain, Netherlands and Belgium) for plants and flower visiting insects. We comp...
The Last Glacial Maximum distribution of South African subtropical thicket inferred from community distribution modellingNARA Subscribed
Aim Southern Africa lacks the palaeo‐archives needed to infer regional vegetation history. The megadiverse subtropical thicket of South Africa, locally termed the Albany subtropical thicket ( AST ), is postulated to have experienced severe reductions in range during the Pleistocene glacial periods. Here we test this glacial contraction hypothesis using spatial predictions from climate envelope models to explore the distributio...
Forest Policy / BiosecurityNARA Subscribed
7Massive fires in Indonesian peatlands in the 1990s and in eastern Russian peatlands in 2002 and last year have highlighted the need to manage forests overlying peat deposits, as well as converted peat forests and open peatlands. Peat or peaty soils, contain 65% or more of partially decayed vegetation, can burn freely or underground. They cover some 10 percent of worldwide forests and contain 25 percent of all terrestrial carb...
