CBC02 Winter-spring survival and response of birds to variable climate using mist-net captures at Konza Prairie
This dataset includes captures of small-bodied landbirds captured via passive mist-netting efforts. The objectives are to (a) initiate a long-term survey of the non-breeding birds of the site, (b) understand the behavioral and physiological mechanisms that allow birds to cope with the unpredictable, variable, and often harsh conditions during winter months, and (c) provide a training platform for students. The collection of this dataset is fully integrated into the teaching of “Wild Bird Research” (an undergraduate hands-on research course in the Division of Biology) and less formal instruction in bird research methods for graduate students. Additionally, the banding efforts have benefited from the engagement of Konza Prairie docents and frequently hosts class visits and other visitors interested in witness bird banding operations.

Hubbard Brook Experimental Forest: In-situ Nitrogen Mineralization and Nitrification measurements for 4 winter climate change projects
These data are from four separate projects undertaken between 1997 and 2017. The first of these are two snow manipulation (freeze) projects: 1) In 1997, as part of a study of the relationships between snow depth, soil freezing and nutrient cycling, we established eight 10 x 10-m plots located within four stands; two dominated (80%) by sugar maple (SM1 and SM2) and two dominated by yellow birch(YB1 and YB2), with one snow reduction (shoveling) and one reference plot in each stand. 2) In 2001, we established eight new 10-m x 10-m plots (4 treatment, 4 reference) in four new sites; two high elevation, north facing and (East Kineo and West Kineo) two low elevation, south facing (Upper Valley and Lower Valley) maple-beech-birch stands. To establish plots, we cleared minor amounts of understory vegetation from all (both treatment and reference) plots (to facilitate shoveling). Treatments (keeping plots snow free by shoveling through the end of January) were applied in the winters of 1997/98, 1998/99, 2002/2003 and 2003/2004. The Climate Gradient Project was established in October 2010. Here we evaluated relationships between snow depth, soil freezing and nutrient cycling along an elevation/aspect gradient that created variation in climate with little variation in soils or vegetation. We established 6 20 x 20-m plots (intensive plots) and 14 10 x 10-m plots (extensive plots), with eight of the plots facing north and twelve facing south. The Ice Storm project was designed to evaluate the damage and changes ice storms cause to northern hardwood forests in forest structure, nutrient cycling and carbon storage. Ten 20x30 meter plots were established in a predominately sugar maple stand, with 4 icing treatments and 2 control plots. The treatments are as follows: Low (0.25"), Mid (0.5"), Midx2 (0.5") 2 Years in a row, High: (0.75"), Control. The icing treatment was conducted in the winter of 2015-2016, with a second year of icing on the Midx2 treatments plots in the winter of 20

Data from: Earlier flowering of winter oilseed rape compensates for higher pest pressure in warmer climates
<p>Pest abundance and timing of migration relative to the vulnerable crop stage influence the severity of crop damage and yield loss to insect pests in oilseed rape (OSR). Both abundance and timing are influenced by landscape composition, changes therein due to crop rotation, and temperature. The need for sustainable and temperature-adapted management strategies of OSR pests due to the environmental harm of current conventional practices and global warming calls for a better understanding of the combined effects of landscape composition and temperature on pest abundances, larval parasitism, crop damage and yield, but also of the role of crop phenology for crop damage and yield under field conditions. Here, 29 winter OSR crops were studied along a multi-annual mean temperature gradient (MAT, 1981–2010) in Bavaria, Germany. We measured pest abundances (pollen beetles, stem weevils), crop damage (bud loss, stem tunnelling), pollen beetle larval parasitism and crop yield and calculated Julian dates of flowering from biweekly observations of growth stages. Pest abundances and parasitism were analysed with regard to MAT and landscape parameters at six scales (non-crop habitat and OSR area, change in the proportion of OSR area relative to the previous year; 0.6 km, and 1–5 km in 1-km steps), while analysis of crop damage and yield also included Julian date of flowering. Pollen beetle abundance was increased under higher MAT, but less strongly when OSR proportions were high (1-km scale) and not strongly reduced relative to the previous year (5-km scale), while pollen beetle larval parasitism was overall low but exceeded 30% (considered as threshold for effective natural control) occasionally under both low and high MAT. In contrast to abundance of adult pollen beetles, stem weevil larval abundance – as well as stem damage – did not respond to landscape composition nor MAT. Despite high abundance of adult pollen beetles under high MAT, crop yield was high (and the proportion of bud loss low) under high MAT when OSR flowered early. Our results underpin the potential of targeted landscape management (e.g. through regionally coordinated crop rotations) and timing of flowering (e.g. through cultivar choice) for environment-friendly and temperature-adapted pest management in winter OSR.</p>

Data from: Climate synchronises shrub growth across a high-arctic archipelago: contrasting implications of summer and winter warming
<p>Climate change is most pronounced at high latitudes, where plant and animal populations are often strongly influenced by environmental fluctuations related to climate and weather. Environmental conditions can co-fluctuate over large distances and thereby synchronise primary production in space. However, large-scale studies of such spatiotemporal patterns remain rare in the Arctic, where short time-series and poor spatial replication have characterised the data available on both biotic and abiotic parameters. Here, we use dendrochronological tools to measure ring growth of a dominant dwarf shrub, the polar willow (<i>Salix polaris</i> Wahlenb.), previously found to reliably trace community-level vascular plant biomass production. We investigated climate drivers of vegetation growth and their role in the synchronisation of primary production across the rapidly warming archipelago of Svalbard (n = 8 sites, composed of 17 sub-sites, 0.06-293 km apart). We found contrasting effects of summer versus winter weather on ring growth and its spatial synchrony. Although an overall positive effect of summer temperature caused spatially synchronous growth, negative impacts of winter rain-on-snow events occurred only locally, potentially counteracting such synchrony. However, the anticipated increase in both summer temperature and spatial extent of rain-on-snow events, causing basal ice encapsulation of the vegetation, could change the relative importance of seasons for spatiotemporal dynamics of shrub growth. Because these shrub ring growth chronologies reflect annual fluctuations in total vascular plant biomass, fuelling the bottom-up controlled food-web, these results have large implications for our understanding of how climate change shapes tundra ecosystem productivity in time and space.</p>
Data from: They like it cold, but only in winter: climate‐mediated effects on a hibernator
<ol> <li>Variations in ambient temperature (T<sub>a</sub>) profoundly influence energy consumption in endotherms and therefore their survival and fitness. But depending on whether endotherms are hibernating or active, the same changes in T<sub>a</sub> may have opposing consequences for their energy consumption.</li> <li>The aim of this study was therefore to investigate how variations in T<sub>a</sub>, occurring during hibernation and during the active period of a hibernator, affect different fitness relevant traits.</li> <li>To understand whether changes in T<sub>a</sub> impact phenology, body mass and reproduction in a small mammalian hibernator, we analysed T<sub>a</sub> variations and detailed capture-mark-recapture data on edible dormice (Glis glis) collected between 1993 and 2016 in South-West Germany.</li> <li>Results revealed that during hibernation a T<sub>a</sub> increase of 1°C advanced the date of first capture after hibernation by 6 days, but only if food availability during the preceding year was low. In contrast, after years of comparatively high food availability, date of first capture was not affected by T<sub>a</sub>, but dormice had a significantly lower body mass after emergence, if T<sub>a</sub> during hibernation was elevated (3 to 6g per 1°C). We presume that an earlier emergence as well as a lower body mass after emergence potentially reduce the chance to survive.</li> <li>During the active period of edible dormice, mean spring T<sub>a</sub> a did not affect the date of birth but was positively associated with litter size, potentially improving reproductive success.</li> <li>Results of this study highlight that, depending on the physiological state of a hibernator, an increase in T<sub>a</sub> can have positive and negative effects on fitness relevant traits.</li> </ol>

Data from: Climatic influences on winter precipitation use by trees in summer
<p>Trees in seasonal climates may use water originating from both winter and summer precipitation. However, the seasonal origins of water used by trees have not been systematically studied. We used stable isotopes of water to compare the seasonal origins of water found in three common tree species across 24 Swiss forest sites sampled in two different years. The data set provides information on the sites (e.g., latitude/longitude, site name), site characteristics (e.g., weather/climate), tree species studied (beech, spruce and oak), and corresponding observations of stable isotopes of hydrogen and oxygen in tree xylem water. </p>
Data from: Climate drives body mass changes in a mountain ungulate: Shorter winters lead to heavier Alpine ibex
<p>Climate affects seasonality and plant phenology, which can influence seasonal body mass dynamics of herbivores in temperate environments. We investigated long-term trends of seasonal body mass changes in male Alpine ibex (<em>Capra ibex</em>). We used SEM to test direct and indirect relationships between body mass, mass changes and environmental and climatic variables. Individually recognizable Alpine ibex were weighed repeatedly between 2000 and 2022 in Gran Paradiso National Park (Italy). Autumn mass increased substantially over these two decades, up to 15% in some age classes. Over the same time frame, both summer mass gain and winter mass loss decreased, suggesting that heavier autumn body mass was due to the cumulative effects of reduced mass loss over several winters. The environmental factor with the strongest effects on winter mass changes was the starting date of vegetation green-up at low altitude, where ibex gather after winter to feed on new growth vegetation. Early springs led to lower winter mass loss, likely because ibex relied on stored fat for a shorter period and had greater access to forage. High population density also increased winter mass loss. Environmental conditions and resource availability, possibly also influenced by density in winter and early spring seem therefore to directly affect the body mass dynamics of male Alpine ibex, while the effect of summer conditions appears less relevant. By affecting seasonal body mass dynamics, climate change may have consequences for life history and population dynamics of mountain herbivores, for example via earlier access of young males to reproduction.</p>
