title: Data from: A test of the competitive ability – cold tolerance trade-off hypothesis in seasonally breeding beetles

description: Closely related species that use similar resources often differ in their
 seasonal patterns of activity, but the factors that limit their
 distributions across seasons are unknown for most species. One hypothesis
 to explain seasonal variation in the distributions of species involves a
 trade-off between competitive ability and cold tolerance, where tolerance
 to the cold compromises competitive ability in warmer (benign)
 temperatures, either at the level of the individual or population. We
 tested both individual-level and population-level mechanisms of this
 hypothesis in two co-occurring species of temperate burying beetles
 (Silphidae: Nicrophorus sayi, N. orbicollis) that differ in their seasonal
 patterns of activity. We measured cold tolerance, breeding activity as a
 function of temperature, and competitive ability as a function of
 temperature and season. Consistent with our hypothesis, the mid-season N.
 orbicollis was less able to function at the cold temperatures that
 characterize early spring, when the early-season N. sayi is most active.
 The larger beetle, however, always won one-on-one competitive trials at
 warm temperatures, regardless of species, inconsistent with an
 individual-level trade-off. N. orbicollis was usually larger and
 successful when competing for the same carrion later in the season, mostly
 because of its larger population size, consistent with a trade-off between
 competitive ability and cold tolerance acting at the population level. Our
 findings suggest that cold temperatures limit the mid-season N. orbicollis
 from earlier spring emergence, while competitive pressure from the more
 abundant, larger N. orbicollis constrains the early-season N. sayi from
 remaining active through the summer.

title: Data from: Integrating demographic niches and black spruce range expansion at subarctic treelines

description: When investigating relationships between species’ niches and
 distributions, niches can be divided demographically, resulting in unique
 niches for different life stages. This approach can identify changing
 substrate requirements throughout a species’ life cycle. Using non-metric
 multidimensional scaling, we quantified microsite conditions associated
 with successful recruitment in the tundra landscape and successful seed
 production amongst adult trees of black spruce (Picea mariana) at
 subarctic treeline in Yukon, Canada to assess how life stage-specific
 requirements may impact the distribution of this widespread boreal tree
 species. Treeline ecotones in this region showed high heterogeneity in
 tundra microsites available for establishment. Black spruce exhibited
 changing microsite associations from germination to reproductive maturity,
 which were mainly driven by changes in plant community and soil moisture.
 These associations limit the microsites where individuals can establish
 and reproduce to a subset available within the heterogeneous landscape.
 Overall, we suggest that (1) substrates suitable for early recruitment are
 limited at the range edge; and (2) reproductive adults have a narrow
 niche, limiting successful seed production in adults and forming sink
 populations where suitable conditions are limited. Our multivariate
 assessment of microsite suitability can provide valuable insights into the
 spatial distribution of a species throughout its life cycle and identify
 life stage-specific constraints to range expansion.

title: Data for: Herbivores’ impacts cascade through the brown food web in a dryland

description: Food webs can be conceptualized as being powered by energy derived from
 living and dead vegetation, respectively. Most food web research has
 focused on “green food webs” which begin with the consumption of living
 vegetation by herbivores. However, “brown food webs” which stem from the
 consumption of senescent vegetation by detritivores are also an important
 channel of energy transfer. In theory, herbivores have the potential to
 disrupt brown food webs by consuming plant material before it has the
 opportunity to senesce and become available for detritivores. Here we
 investigate the effects that grazing by kangaroos whose population had
 irrupted in the absence of an apex predator has on the brown food web in
 an arid environment. We compared the cover of living and dead vegetation
 and the abundances of detritivorous termites and their predators inside
 one ha herbivore exclosures and nearby control plots. Results show there
 was more cover of living and dead vegetation inside the exclosures.
 Similarly, abundances of termites and small vertebrate predators of
 termites were greater inside the exclosures. Our study provides evidence
 that consumption of plant material by irruptive herbivores can disrupt the
 functioning of the brown food web by reducing the flow of energy from
 plant biomass to termites which in turn translates to reduced abundances
 of termites and small vertebrates that feed on termites. Our findings have
 implications for conservation and management because they shed light on a
 previously unconsidered threat to the functioning of arid ecosystems,
 disruption of brown food webs by irruptive herbivores.

title: Raw, unprocessed SEM data images for: Figure 1: Scanning electron microscope images of “type-1 bone collagen” demineralized bone matrix fibrils

description: Raw, unprocessed SEM data images for Figure 1 of the manuscript: Scanning
 electron microscope images of “type-1 bone collagen” demineralized bone
 matrix fibrils. (A) Fibrils from the B. taurus extant long bone control.
 Prominent banding (~67nm) is present that is characteristic of type-1
 collagen protein fibrils (Boatman et al., 2019; Gottardi et al., 2016; Lin
 et al., 1993; Rabotyagova et al., 2008; Tzaphlidou, 2005). (B) Permafrost
 YG 610.2397 M. primigenius demineralized bone matrix fibrils. An ~67nm
 banding pattern on the fibrils is also observed but is somewhat less
 distinct in comparison to that of the extant B. taurus specimen. (C)
 Observed fibril structures in the temperate MOR 91.72 M. columbi specimen.
 Fibril banding is generally absent, suggesting the original chemical state
 of the type-1 collagen fibrils/sequences is substantially altered.
description: An ~200-300 mg fragment of each specimen was demineralized in
 EDTA (0.5M, pH 8.0) for ~1-3 days, fixed for 1 hour in 2.5% glutaraldehyde
 (multiple washes in phosphate-buffered saline were performed before and
 after fixation to remove glutaraldehyde), and dehydrated in a graded
 series of ethanol incubations (1 hour at 50%, 1 hour 70%, 1 hour 95%, 3x 1
 hour 100% ethanol). Post dehydration, specimens were critical point dried
 (Tousimis Semidri PVT-3), sputter coated (Cressington 108 Auto) with ~70
 angstroms of palladium gold metal, and imaged with a Hitachi S-4700 Cold
 Cathode Field Emission Scanning Electron Microscope. All images were taken
 at 50,000x magnification and with an accelerating voltage of 15.0kV.
 Resultant electron microscope images were processed in Adobe Photoshop
 2021, using the Levels tool, with a histogram stretch, followed by a gamma
 adjustment, followed by a second histogram stretch. Sample preparation for
 ancient specimens was done in a dedicated “ancient” clean lab separate
 from the extant control, and was performed wearing gloves, a laboratory
 coat, a surgical mask, and a bouffant cap. Sampling of ancient specimens
 was done using a hammer and chisel sterilized with 10% bleach followed by
 70% ethanol. Laboratory surfaces near preparatory areas for ancient
 samples were also sterilized with 10% bleach followed by 70% ethanol, and
 all glassware and consumables were autoclaved prior to use. Solutions for
 ancient specimens were vacuum filtered (0.220 microns) prior to use in
 preparation protocol. For critical point drying, sputter coating, and
 imaging, samples were transported from the clean lab to the CHANL core
 facility at the University of North Carolina at Chapel Hill.

title: Micro-scale spatial preference and temporal cyclicity linked to foraging in harbour porpoises

description: Habitat heterogeneity is a crucial driver for species distribution across
 scales. Harbour porpoise Phocoena phocoena basin-wide
 distribution is linked to prey availability, and small-scale (kilometres
 to tens of kilometres) differences in distribution are prevalent. However,
 information on porpoise distribution and foraging-behaviour variations on
 a micro-scale (hundred meters to kilometres) is limited. To monitor
 harbour porpoise distribution and foraging activity on a micro-scale we
 deployed passive acoustic dataloggers, logging porpoise acoustic activity
 at six sites in a small, high porpoise-density area in southern Sweden.
 Data were collected for almost a year, giving detailed time series on
 porpoise activity. The time series were analysed using dynamic time
 warping to compare activity patterns between sites. Large differences were
 found between sites separated by only a few hundred meters, indicating
 micro-scale spatial preference. Spectral analysis for temporal cyclicity
 in activity revealed a dominant peak for 24-hour cycles with higher
 activity during the night for all sites. All sites also had a second peak
 for 29.5 days, linked to the lunar cycle with higher activity during the
 full moon. Activity was overall highest during autumn and winter
 (September–December). Spatial and temporal patterns were linked to
 foraging, showing a positive correlation between porpoise presence and the
 percent of time present with detected foraging. The study demonstrates
 that harbour porpoise spatial distribution on a micro-scale should be
 considered in e.g. behavioural, management, and conservation studies and
 actions. In addition, we show that time series statistical methodology,
 such as dynamic time warping and spectral analysis, are informative and
 appropriate for analysis of acoustic temporal data.

title: Interspecific tandem flights in nocturnally migrating terrestrial birds

description: We report some interspecific nocturnal tandem flights involving the
 Eurasian woodcock and other terrestrial non-passerine species such as the
 Japanese green pigeon in two bird observatories in northern Japan. Our
 observation suggests that this previously undescribed interspecific
 interaction may be a novel form of commensalism or mutualism in nocturnal
 migrants. Here we upload the supporting dataset that includes the date and
 time, abundance, the presence/absence of nocturnal flight calls, flight
 direction, flight altitude, and observation location for each observed
 pass-by species.

title: European Space Administration Snow Climate Change Initiative (Snow_cci): Snow Water Equivalent (SWE) level 3C daily global climate research data package (CRDP) (1979 – 2020), version 2.0

description: This dataset contains v2.0 of the Daily Snow Water Equivalent (SWE) product from the European Space Administration (ESA) Climate Change Initiative (CCI) Snow project, at 0.1 degree resolution.
 Snow water equivalent (SWE) indicates the amount of accumulated snow on land surfaces, in other words the amount of water contained within the snowpack. The SWE product time series covers the period from 1979/01 to 2020/05. Northern Hemisphere SWE products are available at daily temporal resolution with alpine areas masked.
 The dataset is aimed to serve the needs of users working on climate research and monitoring activities, including the detection of variability and trends, climate modeling, and aspects of hydrology and meteorology.
 The Finnish Meteorological Institute is responsible for the SWE product development and generation.
 This version 2 dataset has some notable differences compared to the v1 data. In v2, passive microwave radiometer data are obtained from the recalibrated enhanced resolution CETB ESDR dataset (MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature (CETB) Earth System Data Record (ESDR) https://nsidc.org/pmesdr/data-sets/), the grid spacing is reduced from 25 kilometers (km) to 12.5 km, and spatially and temporally varying snow density fields are used to adjust SWE retrievals in post processing. The output grid spacing is reduced from 0.25-degree to 0.10-degree WGS84 latitude / longitude to be compatible with other Snow_cci products. The time series has been extended by two years with data from 2018 to 2020 added.
 The ESA CCI phased product development framework allowed for a systematic analysis of these changes to the input data and snow density parameterization that occurred between v1 and v2 using a series of step-wise developmental datasets. In comparison with in-situ snow courses, the correlation and Root Mean Squared Error (RMSE) of v2 improved 18 percent (%) (0.1) and 12% (5 millimeters (mm)), respectively, relative to v1. The timing of peak snow mass is shifted two weeks later and a temporal discontinuity in the monthly northern hemisphere snow mass time series associated with the shift from the Special Sensor Microwave/Imager (SSM/I) and the Special Sensor Microwave Imager/Sounder (SSMIS) in 2009 is removed in v2.

title: ERA5-Land hourly data from 1950 to present

description: ERA5-Land (European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis) is a reanalysis dataset providing a consistent view of the evolution of land variables over several decades at an enhanced resolution compared to ERA5. ERA5-Land has been produced by replaying the land component of the ECMWF ERA5 climate reanalysis. Reanalysis combines model data with observations from across the world into a globally complete and consistent dataset using the laws of physics. Reanalysis produces data that goes several decades back in time, providing an accurate description of the climate of the past.
 ERA5-Land uses as input to control the simulated land fields ERA5 atmospheric variables, such as air temperature and air humidity. This is called the atmospheric forcing. Without the constraint of the atmospheric forcing, the model-based estimates can rapidly deviate from reality. Therefore, while observations are not directly used in the production of ERA5-Land, they have an indirect influence through the atmospheric forcing used to run the simulation. In addition, the input air temperature, air humidity and pressure used to run ERA5-Land are corrected to account for the altitude difference between the grid of the forcing and the higher resolution grid of ERA5-Land. This correction is called 'lapse rate correction'.
 The ERA5-Land dataset, as any other simulation, provides estimates which have some degree of uncertainty. Numerical models can only provide a more or less accurate representation of the real physical processes governing different components of the Earth System. In general, the uncertainty of model estimates grows as we go back in time, because the number of observations available to create a good quality atmospheric forcing is lower. ERA5-land parameter fields can currently be used in combination with the uncertainty of the equivalent ERA5 fields.
