Contrasting effects of land-use changes on herbivory and pollination networks
<ol> <li>Land-use changes, one of the greatest threats to global biodiversity, can cause under-appreciated effects on ecosystems by altering the structures of interspecific interaction networks. These effects have typically been explored by evaluating interaction networks composed of a single type of interaction. Therefore, it remains unclear whether the different types of interaction networks sharing the same species respond to the same land-use changes in a similar manner.</li> <li>To compare the responses of herbivory and pollination networks to land-use changes, we investigated both types of interaction networks in semi-natural grasslands categorized into three types of agricultural land-use (abandoned, extensively managed, and intensively managed) in a Japanese agricultural landscape. We quantified the structures of the interaction networks using several indices (connectance, evenness, diversity, generality, network specialization, and robustness) and compared them among different land-use types. We conducted piecewise SEM to differentiate the direct and indirect effects of land-use changes on the network structures.</li> <li>Although both land-use changes (abandonment and intensification) led to reduced plant and insect species richness, the structures of herbivory and pollination networks showed different responses to the land-use changes. There was a marked contrast in network generality; while herbivore species were less generalized (i.e. having fewer host plant species) in fields with land-use intensification, pollinator species were less generalized in abandoned fields.</li> <li>Furthermore, the mechanisms behind the changes in interaction networks were also different between pollination and herbivory networks. The change in herbivory network generality was induced by the decrease in plant species richness, whereas the change in pollination network generality was mainly induced by the effect independent of changes in species richness and composition, which possibly reflect the less number of flowers in shaded environment.</li> <li>The present study demonstrates that agricultural land-use changes affect herbivory and pollination networks in contrasting ways and suggests the importance of assessing multiple types of interaction networks for biodiversity conservation in plant–insect systems. Our results also highlight the under-appreciated importance of maintaining habitats with an intermediate intensity of land-use.</li> </ol>
A meta-analysis of tropical land-use change effects on the soil microbiome: emerging patterns and knowledge gaps
<p>Modifications to vegetation and soil due to changes in land use have the potential to alter the soil microbiome, with consequences for carbon and nutrient cycling. Despite the important function of soil microorganisms, little is known about their response to land-use change, especially in tropical regions where current rates of land conversion are greatest. The aim of this meta-analysis was to examine how land-use change influences soil microbial properties in tropical ecosystems and to identify current trends and knowledge gaps in the literature. We identified 83 published paired studies that reported data on microbial biomass, abundance, composition, and enzyme activity under representative land-use changes in the tropics. We calculated response ratios for studies that compared the following: reference forests to (a) agriculture, (b) pastures, (c) plantations, and (d) secondary forests. Here you will find all the raw and clean data used for the meta-analysis. </p>
Data from: Extreme climate events counteract the effects of climate and land-use changes in Alpine treelines
Climate change and extreme events, such as drought, threaten ecosystems world-wide and in particular mountain ecosystems, where species often live at their environmental tolerance limits. In the European Alps, plant communities are also influenced by land-use abandonment leading to woody encroachment of subalpine and alpine grasslands. In this study, we explored how the forest–grassland ecotone of Alpine tree lines will respond to gradual climate warming, drought events and land-use change in terms of forest expansion rates, taxonomic diversity and functional composition. We used a previously validated dynamic vegetation model, FATE-HD, parameterized for plant communities in the Ecrins National Park in the French Alps. Our results showed that intense drought counteracted the forest expansion at higher elevations driven by land-use abandonment and climate change, especially when combined with high drought frequency (occurring every 2 or less than 2 years). Furthermore, intense and frequent drought accelerated the rates of taxonomic change and resulted in overall higher taxonomic spatial heterogeneity of the ecotone than would be expected under gradual climate and land-use changes only. Synthesis and applications. The results from our model show that intense and frequent drought counteracts forest expansion driven by climate and land-use changes in the forest–grassland ecotone of Alpine tree lines. We argue that land-use planning must consider the effects of extreme events, such as drought, as well as climate and land-use changes, since extreme events might interfere with trends predicted under gradual climate warming and agricultural abandonment.

Data from: Global change on the Roof of the World: vulnerability of Himalayan otter species to land-use and climate alterations
<p>Climate Change Vulnerability Assessment (CCVA) prescribes the quantification of species vulnerability based on three components: sensitivity, adaptive capacity and exposure. Such assessments should be performed through combined approaches that integrate trait-based elements (e.g., measures of species sensitivity such as niche width) with correlative tools quantifying exposure (magnitude of changes in climate within species habitat). Furthermore, as land-use alterations may increase climate impacts on biodiversity, CCVAs should focus on both climate and land-use change effects. Unfortunately, most of such assessments have so far focused exclusively on exposure to climate change. </p> <p>We evaluated the vulnerability of three otter species occurring in the Himalayan region, i.e. <i>Aonyx cinereus, Lutra lutra </i>and<i> Lutrogale perspicillata</i>, to 2050 climate and land-use through the recently-proposed Climate Niche Factor Analysis (CNFA) framework combined with Species Distribution Models.</p> <p>Future climate and land-use change will reduce (6 – 15%) and shift (10 – 18%) the geographic range of the three species in the Himalaya, with land-use alterations exerting far more severe effects than climate change. Among vulnerability components, sensitivity played a greater role than exposure in determining the vulnerability of the otters. Specifically, the most specialist species, <i>L. perspicillata</i> showed the highest vulnerability in comparison with the most generalist, <i>L. lutra</i>.</p> <p>Our results underline how coupling climate and land-use change components in CCVAs can generate diverging predictions of species vulnerability compared to approaches relying on climate change only. Moreover, intrinsic components, such as species sensitivity, proved significantly more important in determining vulnerability than extrinsic metrics such as habitat exposure.</p> <p>The dataset contains XY coordinates of Himalayan otter species used in the study. Since Himalayan otters are listed as threatened or vulnerable in several of the regions covered by the study, original coordinates were rounded to 1 degree. Specific data sources are provided in the coupled table.</p>
A dataset to model Levantine landcover and land-use change triggered by climate change, the Arab Spring and COVID-19
<p>The Levant region is highly vulnerable to climate change, experiencing prolonged heat waves that have led to societal crises and population displacement. Since 2010, the area has been marked by socio-political turmoil, including the Syrian civil war, which has strained neighbouring countries like Jordan due to the influx of Syrian refugees. Jordan, in particular, has seen rapid population growth and significant changes in land use and infrastructure, leading to over-exploitation of the landscape through irrigation and construction. This article uses climate data, satellite imagery, and land cover information to illustrate the substantial increase in construction activity and highlights the intricate relationship between climate change predictions and current socio-political developments in the Levant.</p>
