title: Permafrost thaw in boreal peatlands is rapidly altering forest community composition

description: This record is for the dataset “Permafrost thaw in boreal peatlands is rapidly altering forest community composition” at &lt;a href="https://doi.org/10.5061/dryad.0cfxpnw0p"&gt;https://doi.org/10.5061/dryad.0cfxpnw0p&lt;/a&gt;
&lt;p&gt;&lt;p&gt; 

Boreal peatlands are frequently underlain by permafrost, which is thawing rapidly. A common ecological response to thaw is the conversion of raised forested plateaus to treeless wetlands, but unexplained spatial variation in responses, combined with a lack of stand-level data, make it difficult to predict future trajectories of boreal forest composition and structure. We sought to characterize patterns and identify drivers of forest structure, composition, mortality, and recruitment in a boreal peatland experiencing permafrost thaw. To do this, we established a large (10 ha) permanent forest plot (completed in 2014), located in the Northwest Territories, Canada, that includes 40,584 mapped and measured trees. In 2018, we conducted a comprehensive mortality and recruitment recensus. We also measured frost table depth, soil moisture, soil humification, and organic layer thickness within the plot between 2012 and 2018, and used habitat association tests to link these variables to forest characteristics and dynamics. Forest composition and structure varied markedly throughout the plot and were strongly governed by patterns in permafrost presence and organic layer thickness. Overall, there was a net loss of trees from the plot at a rate of 0.7% yr-1. Mortality of black spruce, the dominant tree species, was more than double that of recruitment and was strongly associated with permafrost thaw. In contrast, recruitment of larch was over four times greater than mortality, and occurred primarily in low-lying, permafrost-free wetlands with mineral soil near the surface. The trends in tree demography and underlying drivers suggest that spruce-dominated permafrost plateaus will be converted into larch-dominated wetlands as permafrost thaw progresses in boreal peatlands, particularly in areas where mineral soil is near the surface. In the longer term, thaw could increase the hydrologic connectivity of the landscape, resulting in widespread drainage and re-vegetation by spruce, but we did not find evidence that this is occurring yet. Given the increasing rates of permafrost thaw, and positive feedbacks between thaw and forest change, we predict that larch abundance will continue to increase in boreal peatlands over the coming decades, leading to shifts in ecosystem function, wildlife habitat, albedo, and snow dynamics. &lt;p&gt;

title: Topsoil temperature data below different vegetation types at Trail Valley Creek, Canada, 2016-2018

description: This record is for the dataset “Topsoil temperature data below different vegetation types at Trail Valley Creek, Canada, 2016-2018” at &lt;a href="https://doi.org/10.1594/PANGAEA.918615"&gt;https://doi.org/10.1594/PANGAEA.918615&lt;/a&gt;
&lt;p&gt;&lt;p&gt; 

This dataset contains topsoil temperature data of 68 sensors, which were installed at the Arctic tundra site of Trail Valley Creek, Northwest Territories, Canada (133.499 °W, 68.742 °N). The sensors were located below six different vegetation types (trees, tall shrubs, riparian tall shrubs, dwarf shrubs, tussocks and lichen tundra) at a depth of 1 to 5 cm, protected from solar radiation. The sensors were placed between 0.22 m to more than 1 km apart from each other. The mean distance between nearest neighbouring sensors was 10.65 m. The sensor network is designed to monitor the effects of changing surface parameters such as vegetation, micro topography and soil moisture on seasonal thawing and freezing processes and on long-term warming of permafrost temperatures. The topsoil temperature was measured using coated iButton temperature loggers (DS1922L) at 0.0625°C resolution and an accuracy of 0.5° C (Maxim Integrated Products, Inc., 2015). The record covers the two periods from 28th of August 2016, 3:00 to 3rd of September 2017, 15:00 and from 4th of September 2017, 12:00 to 22nd of August 2018, 21:00 (UTC, local time + 7 hours) in 3 hourly resolution. Between the two periods, the sensors were removed, read out, and placed at the same positions again. The two periods were analysed by Grünberg et al., 2020, who describe the measurements in more detail.&lt;p&gt;

&lt;p&gt;&lt;p&gt; 

This was an experiment to study the sensitivity of L-band Vegetation Optical Depth (VOD) to changing vegetation water potential over a growing season. As part of the SMAPVEX19-21 campaign, an L-band radiometer was deployed atop a tower in the Harvard Forest, in Petersham, Massachusetts, looking down upon a stand of red oak. Additional instruments were installed within the radiometer's field of view to measure soil moisture and temperature, air temperature, tree xylem apparent dielectric permittivity at 70 MHz, tree xylem water potential, and canopy wetness throughout the same time frame. The radiometer collected data in V-polarization from late April to
mid-October 2019. Also, over four days in early July 2019, the water potential and L-band complex dielectric constant of canopy leaves were measured at various times of day. &lt;p&gt;

title: Baker Creek Research Catchment Hydrometeorological and Hydrological Data

description: This record is for the dataset “ Baker Creek Research Catchment Hydrometeorological and Hydrological Data” at &lt;a href= "https://doi.org/10.20383/101.026 "&gt;https://doi.org/10.20383/101.026 &lt;/a&gt;.

It is uncommon to collect long term coordinated hydrometeorological and hydrological data in northern circumpolar regions. However, such datasets can be very valuable for engineering design, improving environmental prediction tools or detecting change. This dataset documents hydrometeorological and hydrological conditions in the Baker Creek Research Catchment from 2003 to 2016. Baker Creek drains water from 155 km2 of subarctic Canadian Shield terrain in Canada’s Northwest Territories. Seasonal half hourly hydrometeorological, ground temperature and soil moisture data were collected from representative locations, including exposed Precambrian bedrock ridges, peatlands, open black spruce forest and lakes. Hydrometeorological data includes incoming radiation, rainfall, temperature, humidity, winds, barometric pressure, and turbulent fluxes. Spring maximum snowpack water equivalent, depth and density data are included. Daily streamflow data are available from a series of nested watersheds ranging in size from 9 to 128 km2. These data provide the scientific and engineering communities with an opportunity to advance understanding of geophysical processes and improve infrastructure resiliency in this remote region. &lt;p&gt;

title: Dataset to accompany manuscript: Seasonal variation of behavioural thermoregulation in a fossorial salamander (Ambystoma maculatum)

description: Temperature seasonality plays a pivotal role in shaping the thermal biology of ectotherms. However, we still have a limited understanding of how amphibians maintain thermal balance in the face of varying temperatures, especially in fossorial species. Due to thermal buffering underground, thermal ecology theory predicts relaxed selection pressure over thermoregulation in fossorial ectotherms. As a result, fossorial ectotherms typically show low thermoregulatory precision and low evidence of thermotactic behaviours in laboratory thermal gradients. Here, we evaluated how temperature selection (Tsel) and associated behaviours differed between seasons in a fossorial amphibian, the Spotted Salamander (Ambystoma maculatum). By comparing thermoregulatory parameters between the active and overwintering seasons, we show that A. maculatum engages in active behavioural thermoregulation despite being fossorial. In both seasons, Tsel was consistently offset higher than acclimatisation temperatures. Thermoregulation differed between seasons, with salamanders having higher Tsel and showing greater evidence of thermophilic behaviours in the active compared to the overwintering season. Additionally, our work lends support to experimental assumptions commonly made but seldom tested in thermal biology studies. Ultimately, our study demonstrates that the combination of careful behavioural and thermal biology measurements is a necessary step to better understand the mechanisms that underlie body temperature control in amphibians.

title: Communications, media and internet concentration in Switzerland, 2019-2021

description: This data accompanies the report, "Communications, media and internet concentration in Switzerland, 2019-2021". The report examines media concentration in Switzerland from 2019 to 2021. It finds high concentration due to public and multinational companies, especially in telecom and internet services. Switzerland mirrors global trends with declining traditional media revenues but at a slower rate. Public service broadcasting remains influential. The unique Swiss market, with its linguistic diversity and federal structure, lacks transparency due to limited data disclosure requirements, highlighting the need for further investigation.

title: Post-fire Recovery of Soil Organic Layer Carbon in Canadian Boreal Forests, 2015-2018

description: This record is for the dataset “Post-fire Recovery of Soil Organic Layer Carbon in Canadian Boreal Forests, 2015-2018” at &lt;a href= "https://doi.org/10.3334/ORNLDAAC/2235"&gt;https://doi.org/10.3334/ORNLDAAC/2235&lt;/a&gt;. 
&lt;p&gt;&lt;p&gt; 

This dataset provides site moisture, soil organic layer thickness, soil organic carbon, nonvascular plant functional group, stand dominance, ecozone, time-after-fire, jack pine proportion, and deciduous proportion for 511 forested plots spanning ~140,000 km2 across two ecozones of the Northwest Territories, Canada (NWT). The plots were established during 2015-2018 across 41 wildfire scars and unburned areas (no burn history prior to 1965), with 317 plots in the Plains and 194 plots in the Shield regions. At each plot, two adjacent 30-m transects were established 2 m apart, running north from the plot origin. Soil organic layer (SOL) depth (cm) was measured every 3 m and the mean was taken from the 10 measurements to calculate a plot-level SOL thickness. Three soil organic layer profiles were destructively sampled at 0, 12, and 24 m using a corer that was custom designed for NWT soils. Within the transects, all stems taller than 1.37 m were identified to species to calculate tree density (stems / m2). Nonvascular plant percent cover was identified to functional group at five, 1-m2 quadrats spaced 6 m apart along the belt transect. A subset of 2,067 of 5,137 total increments from 1,803 profiles from 421 plots were analyzed for total percent C using a CHN analyzer. Time-after-fire was established using fire history records. For older plots where no known fire history is recorded, tree age was used. Data are for the period 2015-06-11 to 2018-08-24 and are provided in comma-separated values (CSV) format. &lt;p&gt;

Snowpack microstructure controls the transfer of heat to, and the temperature of, the underlying soils. In situ measurements of snow and soil properties from four field campaigns during two different winters (March and November 2018, January and March 2019) were compared to an ensemble of CLM5.0 (Community Land Model) simulations, at Trail Valley Creek, Northwest Territories, Canada. Snow Micro Penetrometer profiles allowed snowpack density and thermal conductivity to be derived at higher vertical resolution (1.25 mm) and a larger sample size (n = 1050) compared to traditional snowpit observations (3 cm vertical resolution; n = 115). Comparing measurements with simulations shows CLM overestimated snow thermal conductivity by a factor of 3, leading to a cold bias in wintertime soil temperatures (RMSE = 5.8 ℃). Bias-correction of the simulated thermal conductivity (relative to field measurements) improved simulated soil temperatures (RMSE = 2.1 ℃). Multiple linear regression shows the required correction factor is strongly related to snow depth (R2 = 0.77, RMSE = 0.066) particularly early in the winter. The use of an alternative parameterization of snow thermal conductivity also improved simulations of wintertime soil temperatures (RMSE = 2.5 ℃). Furthermore, CLM simulations did not adequately represent the observed high proportions of depth hoar. Addressing uncertainty in simulated snow properties and the corresponding heat flux is important, as wintertime soil temperatures act as a control on subnivean soil respiration, and hence impact Arctic winter carbon fluxes and budgets.&lt;p&gt;
