Geographic and Genomic Signatures of a Dynamic Evolutionary History in Lake Tanganyika's Synodontis Catfish RadiationNARA Subscribed
Aim Lacustrine systems generally exhibit greater habitat stability than riverine systems, yet some lakes have experienced substantial lake‐level fluctuations throughout the Pleistocene. These environmental perturbations repeatedly altered habitat availability critical to the evolution of their diverse fish communities. In this context, we inferred phylogenetic relationships and divergence times of lacustrine Synodontis catfish...
Obligate brood parasites delegate the workload of costly parental care to their hosts. Theory predicts that release from demanding parental care increases the importance of other factors to shape mating patterns. However, behavioural observations and parentage estimates are notoriously difficult to obtain in species with covert reproductive strategies, such as brood parasites, and evidence for their mating strategies are scarc...
Terrestrial ecosystems affect climate by reflecting solar irradiation, evaporative cooling, and carbon sequestration. Yet very little is known about how plant traits affect climate regulation processes (CRPs) in different habitat types. Here, we used linear and random forest models to relate the community‐weighted mean and variance values of 19 plant traits (summarized into eight trait axes) to the climate‐adjusted proportion...
Lack of host specialization despite selective host use in brood parasitic cuckoo catfishNARA Subscribed
Host–parasite dynamics involve coevolutionary arms races, which may lead to host specialization and ensuing diversification. Our general understanding of the evolution of host specialization in brood parasites is compromised by a restricted focus on bird and insect lineages. The cuckoo catfish ( Synodontis multipunctatus ) is an obligate parasite of parental care of mouthbrooding cichlids in Lake Tanganyika. Given the ecologic...
Soil–plant interactions modulated water availability of Swiss forests during the 2015 and 2018 droughtsNARA Subscribed
Central Europe has been experiencing unprecedented droughts during the last decades, stressing the decrease in tree water availability. However, the assessment of physiological drought stress is challenging, and feedback between soil and vegetation is often omitted because of scarce belowground data. Here we aimed to model Swiss forests' water availability during the 2015 and 2018 droughts by implementing the mechanistic soil‐...
Global maps of soil temperatureNARA Subscribed
Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1‐km 2 r...
Key message Phosphoglycerate Dehydrogenase 1 of the phosphorylated pathway of serine biosynthesis, active in heterotrophic plastids, is required for the synthesis of serine to enable plant growth at high rates of indolic glucosinolate biosynthesis. Abstract Plants have evolved effective strategies to defend against various types of pathogens. The synthesis of a multitude of specialized metabolites represents one effective appr...
Aboveground vertebrate and invertebrate herbivore impact on net N mineralization in subalpine grasslandsNARA Subscribed
Aboveground herbivores have strong effects on grassland nitrogen (N) cycling. They can accelerate or slow down soil net N mineralization depending on ecosystem productivity and grazing intensity. Yet, most studies only consider either ungulates or invertebrate herbivores, but not the combined effect of several functionally different vertebrate and invertebrate herbivore species or guilds. We assessed how a diverse herbivore co...
Increasing soil methane sink along a 120‐year afforestation chronosequence is driven by soil moistureNARA Subscribed
Upland soils are important sinks for atmospheric methane ( CH 4 ), a process essentially driven by methanotrophic bacteria. Soil CH 4 uptake often depends on land use, with afforestation generally increasing the soil CH 4 sink. However, the mechanisms driving these changes are not well understood to date. We measured soil CH 4 and N 2 O fluxes along an afforestation chronosequence with Norway spruce (Picea abies L.) establishe...
