New publication: Herbivore species and patch heterogeneity modulate #grazing-induced shifts in #soil #nematode trophic structure and energy flux, by @ciskaveen.bsky.social and others. #biodiversity
doi.org/10.1111/1365...
Figure 1 in Ma et al. (2025): "The schematic diagram of the experimental design in Songnen meadow steppe. The study area is characterized as a mosaic of high-salinity and low-salinity patches. The experiment was conducted as a completely randomized block design with nine 25 m × 25 m paddocks being arranged into three blocks. Each block consisted of three grazing treatments: cattle grazing, sheep grazing and ungrazing as a control. From 2017 to 2020, a total of three mature cattle with an average body weight of 350.0 ± 10.5 kg or fifteen sheep with an average body weight of 35.0 ± 1.6 kg were grazed during the initial 2 weeks of each month from June to August, producing comparable moderate intensities."

New publication: Effects of Extreme Climatic Events on Evolutionary Processes. #climatechange #evolution
doi.org/10.1111/gcb....
Figure 4 in Heinen et al. (2025): "Responses to climatic extreme events (ECEs) in relation to species life history strategies (a). Long-lived species such as trees can experience several ECEs during their lifetime. These ECEs (vertical bars) can be of the same or a different kind (bar colors), they can differ in intensity (darkness of the bars) and duration (width of the bars). Impact of ECEs differs depending on their duration in relation to the organism's generation time (grey-white alternating blocks). Generation times at the right are illustrative and hypothetical (e.g., some insects species take several years to complete their lifecycle). Short-lived organisms may experience only a single ECE in their lifetime (e.g., insects, herbaceous plants, small vertebrates), whereas microorganisms may experience extreme stress conditions over many consecutive generations. All these aspects play a role in whether and how species will respond at both ecological and evolutionary time scales. The timing of these events in relation to an organism's developmental stage may further have consequences for the ability of an organism to respond adequately. This may be in particular the case for insects, which often have complex lifecycles with some life stage requiring even different habitat conditions (aquatic vs. terrestrial). In the figure the first ECE may occur when the insect is in the larval stage, while the second ECE of the same type may occur during the adult stage in the next generation. Granted that species survive a given ECE, they may respond in three main ways (b): They can migrate to areas where conditions are better, phenotypic plasticity may allow species to cope with ECEs to some extent as long as these events are not too extreme, or they can evolve adaptations over time. The response trajectories of species (immediate and long term) are largely determined by species-specific life history trats, standing genetic variation in a population (...)"

New publication: Functional diversity of #soil microbial communities increases with ecosystem development, by @ehannula.bsky.social and others. #landabandonment #landusechange #carboncycle
doi.org/10.1038/s414...
Figure 1 in Ranheim Sveen et al. (2025): "Study design. Distribution of (a) sites across a national successional gradient in Sweden, based on (b) a paired grassland and forest sites comprising (c) managed, recently abandoned, and late successional grasslands together with fully afforested reference sites representing the successional endpoint. Soil samples were gathered in the field and sequenced with (d) amplicon and shotgun metagenomics to yield taxonomic and functional microbial community profiles, with the hypothesis that these would change (e) linearly, unimodally, or with threshold responses to succession. Note that the trends are shown as positive, i.e., with increasing diversity here, but may also be negative."

doi.org/10.5194/bg-2...
Figure 1 in Theeuwen et al. (2025): "Conceptual model that describes the vertical potential temperature (black) and specific humidity (grey) profiles of the atmospheric boundary layer (ABL) and the ABL development over two different land cover types (left: bare soil, right: forest). For the vertical profiles holds: moving towards the right θ and q increase. For the ABL over bare soil only the vertical temperature profile is shown and for the ABL over forest only the vertical humidity profile is shown. θ: potential temperature, q specific humidity, LCL: lifting condensation level, BLH: ABL height, dθ: jump in θ at the top of the ABL, dq: jump in q at the top of the ABL, H: sensible heat flux, LE: latent heat flux, G: ground heat flux. The circular arrows at the top of the ABL indicate entrainment from dry and warm air into the ABL. The yellow arrows indicate the incoming solar radiation and the part that is reflected back towards the atmosphere, which varies due to the different albedo of the two land cover types. Throughout the day the ABL deepens. Clouds can develop when the ABL and LCL cross."

New publication: Exposure to high temperatures is fatal for eggs and suppresses growth in a false widow #spider, by @melissahrowe.bsky.social and others. #climatechange #thermalstress #Steatodagrossa
Figure 1 in Dong et al. (2025): "Overview of the temperature regimes applied to eggs (A) and spiderlings (B) of Steotoda grossa. Two types of thermal exposure were applied: fixed thermal stress and simulated heatwave conditions. Temperature regimes are based on summer temperatures in the Netherlands (KNMI): 22 °C (blue lines) is the average maximum temperature, 27 °C (orange) during the day is classified as a ‘summer’ day and 32 °C (red) as ‘tropical’. The standard simulated heatwave consisted of 3 days exposure to 27 °C, followed by 5 days at 32 °C. Spiderling (B) were also exposed to extended heatwave conditions (i.e., 10 days at 27 °C and 10 days at 32 °C), as well as repeated standard and extended heatwaves both with 10 days interval between heatwaves. All treatments shown represent day temperatures. Night temperatures were 10 °C lower."
