Fitness and cold tolerance of Spodoptera frugiperda fed on corn and two winter crops(Original data)
<p>Fall armyworm (FAW) <em>Spodoptera frugiperda</em> is a major migratory and polyphagous pest. Overwintering, migrating and colonizing characters of FAW are closely related to vegetation and host adaptation. In this study, oviposition preference, feeding preference, fitness and cold tolerance of FAW fed on spring & summer crop (corn) and two winter crops (cabbage, <em>Brassica campestris </em>and rape,<em> B. napus</em>). We observed that FAW could complete their life cycle by feeding cabbage and rape, although fitness was not as good as corn. FAW fed on cabbage had higher survival, pupal weight, and host suitability index than rape while larvae preferred to feed on rape leaves and females preferred to lay eggs on rape plants. In addition, FAW larvae fed on cabbage had the shortest recovery time from chill coma compared to corn and rape, indicating that cold tolerance of FAW larvae was improved by feeding on cabbage. Consequently, cabbage could be an ideal host for FAW which needed to survive and reproduction in winter. These results improve our understanding of host selection and adaption of FAW, as well as lay a foundation for the prediction of FAW overwintering.</p>
Point intercept and biomass data for vascular plants in a manipulative experiment of rear-round, winter-only, summer-only grazing, mowing and full exclosure at Molslab, Denmark
<p>Data from two sets of sample quadrats included, both from nine experimental blocks, each replicating the treatments: rear-round grazing, winter-only grazing (summer exclosure), summer-only grazing (winter exclosure), mowing (one annual event in autumn) and full exclosure (no cattle or horse grazing, no mowing, but grazing by wild roe deer and hare).</p> <p>1) Each of the 24 sample plots (six blocks times four treatments, mowing excluded) was first sampled non-destructively with the point intercept method, then above-ground biomass was cut at the soil surface, sorted into species fractions, dried and weighed. Data recording <span>September 1–16, 2020</span>.</p> <p>2) Each of the 45 sample plots (nine blocks times five treatments) was sampled non-destructively with the point intercept method.

Data from: Standing decomposition of dead leaves in winter and its legacy effects should not be ignored in subtropical forests
<p><span>Background and Aims</span></p> <p><span>Dead leaves may remain standing all winter before entering the soil as litter in subtropical forests. However, little is known about the standing decomposition of dead leaves and how this might influence subsequent litter decomposition in the soil. </span></p> <p><span>Methods</span></p> <p><span>We conducted an investigation of the standing decomposition of dead leaves in winter in a subtropical forest. In the following summer, we conducted a decomposition experiment of pre-standing litter (dead leaves picked immediately after leaf </span><span>death) and post-standing litter (dead leaves picked after winter) in the soil using the litterbag method, further exploring the influences of the standing process on subsequent litter decomposition in the soil. </span></p> <p><span>Results</span></p> <p><span>After 159 days of standing decomposition, up to 43% of leaf mass was lost, with lignin and cellulose degraded by 30% and 35%, respectively. After 163 days of decomposition in the soil, the mass losses of pre-standing and post-standing litter were 31% and 52%, respectively. The decomposition rate (k) of post-standing litter was 2 times that of pre-standing litter. Restrained by the low photodegradability of litter in the later stage of decomposition, standing decomposition still conformed to the exponential decomposition model.</span></p> <p><span>Conclusion</span></p> <p><span>The standing decomposition of dead leaves in winter is driven predominantly by the abiotic process of photodegradation with leaching, resulting in substantial carbon loss in the standing phase and a doubling of the subsequent litter decomposition rate in soil, thus profoundly influencing the carbon process of subtropical forest ecosystems.</span> </p>
Dataset from "How does a warm and low-snow winter impact the snow cover dynamics in a humid and discontinuous boreal forest? Insights from observations and modeling in eastern Canada"
<p>The dataset presented below is described in the publication “<em>How does a warm and low-snow winter impact the snow cover dynamics in a humid and discontinuous boreal forest? An observational study in eastern Canada.</em>” from Bouchard et al. (submitted) in the journal Hydrology and Earth System Science.</p> <p>The original dataset includes <strong>monitoring data</strong> collected at Montmorency Forest (47.29°N, 71.17°W) from 15 October 2020 to 15 June 2021 (W20-21) and from 15 October 2021 to 15 June 2021 (W21-22) in a medium-size gap, the small-size gap and under the canopy. The study site is a balsam fir – whit birch stand on a 12° slope of north-east aspect. In the monitoring dataset you can find at the hourly timestep:</p> <ul> <li>Snow depth (cm)</li> <li>Soil temperature at 20 cm, 10 cm and 5 cm below ground surface (°C)</li> <li>Soil-snow interface temperature (°C)</li> <li>Snow temperature every 15 cm from the ground surface (°C)</li> <li>Snow surface temperature (°C)</li> <li>Air temperature (°C)</li> <li>Relative humidity (%)</li> <li>Soil volumetric water content at 15 cm below the ground surface (0 – 1)</li> </ul> <p>The dataset also includes <strong>snow pit observations</strong> taken at Montmorency Forest during W20-21 and during W21-22. Each winter, four (4) snow pits were dug inside medium-size gaps, small-size gaps and at subcanopy locations. Snow pit measurement dates are presented in Bouchard et al. (submitted). Each snow pit includes the vertical profile of:</p> <ul> <li>Snow stratigraphy</li> <li>Snow temperature</li> <li>Snow density</li> <li>Snow specific surface area (SSA)</li> </ul> <p> </p> <p>The snow pit height corresponds to the upper boundary of the topmost snow layer in the stratigraphy profile. For density measurements, the height value corresponds to the center of the 3-cm thick box cutter. For the SSA, the value is measured optically at the top of the sample. This value is representative of the top 1 cm of the snow sample, as this is the typical e-folding depth of 1310 nm radiation in snow. Grain type codes for the snowpack stratigraphy correspond to the <em>International Classification for Seasonal Snow </em>(Fierz et al., 2009):</p> <ul> <li>PP: precipitation particles </li> <li>DF: decomposed and fragmented precipitation particles</li> <li>RG: rounded grains</li> <li>FC: faceted crystals</li> <li>FCxr: rounding faceted particles</li> <li>DH: depth hoar</li> <li>MFpc: melt forms – rounded polycrystals</li> <li>MF: melt forms – clustered rounded grains</li> <li>MFcr: melt forms – melt-freeze crusts</li> <li>IF: ice formations</li> </ul>

Sex makes them sleepy: host reproductive status induces diapause in a parasitoid population experiencing harsh winters
<p>When organisms coevolve, any change in one species can induce phenotypic changes in traits and ecology of the other species. The role such interactions play in ecosystems is central, but their mechanistic bases remain underexplored. Upper trophic level species have to synchronize their life-cycle to both abiotic conditions and to lower trophic level species’ phenology and phenotypic variations. We tested the effect of host seasonal strategy on parasitoid diapause induction by using a holocyclic clone of the pea aphid <em>Acyrthosiphon pisum</em> producing asexual and sexual morphs that are viviparous females (i.e. laying embryos) and oviparous females (laying eggs), respectively, the latter being only present at the end of the growing season. <em>Aphidius ervi</em> parasitoids from populations of contrasted climatic origin (harsh vs. mild winter areas) were allowed to parasitize each morph in a split-brood design and developing parasitoids were next reared under either fall-like or summer-like temperature-photoperiod conditions. We next examined aspects of the host physiological state by comparing the relative proportion of forty-seven metabolites and lipid reserves in both morphs produced under the same conditions. We found that oviparous morphs are cues per se for diapause induction; parasitoids entered diapause at higher levels when developing in oviparous hosts (19.4 ± 3.0%) than in viviparous ones (3.6 ± 1.3%), under summer-like conditions (i.e., when oviparous aphids appear in the fields). This pattern was only observed in parasitoids from the harsh winter area since low diapause levels were observed in the other population, suggesting local adaptations to overwintering cues. Metabolomics analyses show parasitoids’ response to be mainly influenced by the host’s physiology, with higher proportion of polyols and sugars, and more fat reserves being found in oviparous morphs. Host quality thus varies across the seasons and represents one of the multiple environmental parameters affecting parasitoid diapause. Our results underline strong coevolutionary processes between hosts and parasitoids in their area of origin, likely leading to phenological synchronization, and we point out the importance of such bottom-up effects for trait expression, and for the provision of ecosystem services such as biological control in the context of climate change.</p>
