Subsurface Temperature Data from Seven Rock Glaciers in Rocky Mountain National Park and Niwot Ridge LTER, Colorado, USA, 2018-2019
HOBO temperature-sensing data loggers (hereafter, sensors) were placed under the surface of seven rock glaciers predicted to have the presence (n=4) or absence (n=3) of sub-surface ice in Rocky Mountain National Park and near Niwot Ridge Long-term Ecological Research site in Colorado. Sub-surface temperatures were recorded to evaluate habitat differences among American pika populations. All sensors (model H08 pro, H08, or H02; Onset Computer Corporation, onsetcomp.com) recorded temperature (±0.2° Celsius) every one or two hours for one year starting in September 2018. Each rock glacier received at least one sensor, positioned near the center and near pika sign. Three rock glaciers received an additional sensor positioned near the edge of the rock glacier near pika sign. Sensors were placed at similar depths (~0.75 m) and similar aspects.

Carabids data of Pterostichus flavofemoratus and Carabus depressus in the Gran Paradiso National Park (2006, 2007, 2012, 2013)
<p>Understanding risks to biodiversity requires predictions of the spatial distribution of species adapting to changing ecosystems and, to that end, earth observations integrating field surveys prove essential as they provide key figures for assessing landscape-wide biodiversity scenarios. Here, we develop, and apply to a relevant case study, a method suited to merge earth/field observations with spatially explicit stochastic metapopulation models to study the near-term ecological dynamics of target species in complex terrains. Our framework incorporates the use of species distribution models for a reasoned estimation of the initial presence of the target species, and accounts for imperfect and incomplete detection of the species presence in the study area. It also uses a metapopulation fitness function derived from earth observation data subsuming the ecological niche of the target species. This framework is applied to contrast occupancy of two species of carabids (<em>Pterostichus flavofemoratus</em>, <em>Carabus depressus</em>) observed in the context of a large ecological monitoring program carried out within the Gran Paradiso National Park (GPNP, Italy). Results suggest that the proposed framework may indeed exploit the hallmarks of spatially explicit ecological approaches and of remote Earth observations. The model reproduces well the observed <em>in-situ</em> data. Moreover, it projects in the near-term the two species' presence both in space and time, highlighting the features of the metapopulation dynamics of colonization and extinction, and their expected trends within verifiable timeframes.</p>
Stream Temperature Dataset, Fall 2014 - Summer 2015, Rocky Mountian National Park, Colorado, USA
<p>Dataset describing stream temperatures at 18 sites across two adjacent stream networks located in Rocky Mountain National Park, Colorado, USA. Temperature data collected with Onset Pendant waterproof loggers. DateTime format is UTC-7, with no daylight savings time. Temperature units are degrees C. Status column indicates the assumed location of the logger (Active= in water, Inactive = out of water). Elevation, UAA (Upstream Accumulated Area), X, and Y describe characteristics of the logger site. Lake_fraction column describes the fraction of the area draining to a site which is estimated to pass through one or more lakes, and UAA_weighted_mean_lake_elevation describes the mean elevation of upstream lakes, weighted by the UAA of each lake. This dataset accompanies the following publication, wherein it is described in greater detail:</p> <p>Carlson, S. P., & Poole, G. C. (2021).

Grassland African Road Images (GARI): A Driving Dataset from Kenyan Highways and National Parks
<p>A driving dataset collected on grassland roads in Kenyan national parks and highways in western Kenya. The dataset contains images from 20 hours of driving as well the driving signals from the vehicle such as speed, steering, acceleration etc. This is the first driving dataset from Africa to the best of our knowledge. See <em>GARI_dataset_description.pdf</em> for more information.</p>
Data from: Local environment, not local adaptation, drives leaf-out phenology in common gardens along an elevational gradient in Acadia National Park, Maine
PREMISE OF THE STUDY: Climate-driven changes in phenology are substantially affecting ecological relationships and ecosystem processes. The role of variation among species has received particular attention; for example, variation among species' phenological responses to climate can disrupt trophic interactions and can influence plant performance. Variation within species in phenological responses to climate, however, has received much less attention, despite its potential role in ecological interactions and local adaptation to climate change. METHODS: We constructed three common gardens across an elevation gradient on Cadillac Mountain in Acadia National Park, Maine to test population-level responses in leaf-out phenology in a reciprocal transplant experiment. The experiment included three native species: low bush blueberry (Vaccinium angustifolium), sheep's laurel (Kalmia angustifolia), and three-toothed cinquefoil (Sibbaldiopsis tridentata). KEY RESULTS: Evidence for local adaptation of phenological response to temperature varied among the species, but was weak for all three. Rather, variation in phenological response to temperature appeared to be driven by local microclimate at each garden site and year-to-year variation in temperature. CONCLUSIONS: Population-level adaptations in leaf-out phenology appear to be relatively unimportant for these species in Acadia National Park, perhaps a reflection of strong genetic mixing across elevations, or weak differences in selection on phenological response to spring temperatures at different elevations. These results concur with other observational data in Acadia and highlight the utility of experimental approaches to understand the importance of annual and local site variation in affecting phenology both among and within plant species.

Social media images from Peneda-Gerês National Park, Northern Portugal
<p>This dataset contains images from the Peneda-Gerês National Park, Northern Portugal. The images were collected from the Flickr and Wikiloc platforms considering a time period from 2003 to 2017. In respect to the General Data Protection Regulation 2016/679, social media data protected by users’ rights was not downloaded nor analysed. Public data that would potentially contain personal information from social media users was kept anonymous through the study. Data was retrieved through the use of the freely available Flickr’s Application Programming Interface (API), indicating a time window and a bounding box with a pair of coordinates (in our case: minimum latitude: 41.653104; maximum lat.: 42.083595; min. longitude: -8.426270; max. lon.: -7.754076) around Peneda-Gerês. This information was then saved as an excel file with the following attributes: user-id, date taken, latitude, longitude, picture uniform resource locator (url).</p> <p>A first annotation, in the context of cultural ecosystem services (CES), was performed by dividing the photographs of the dataset into “Indoor” and “Outdoor” classes. Only the “Outdoor” pictures were included in this study, since CES are directly connected to nature and environment, which in turn are related to the outside/outdoor. The “Outdoor” images were further divided into two main classes, “Natural” and “Human”, depending on whether the image was dominated by natural or man-made elements. Lastly, a finer annotation for outdoor images was also provided, which encompasses the following six classes: “Species”, “Landscape”, “Nature”, “Human activities”, “Human structures” and “Posing”. “Species” pictures respectively pertained to close-up shots of animals or plants in the wild, translating CES pertaining to biodiversity appreciation. “Landscape” pictures show wide-open shots of nature in the wild, often with a visible horizon most often representing people’s enjoyment of landscape aesthetics. “Human activities” include pictures where people engage in by recreational activities, for instance related to sports such as ski or cycling. “Human structures” include those pictures where man-made structures dominate in the wild, e.g., historical monuments and churches, capturing situations of cultural heritage and spiritual enrichment. “Posing” refers to pictures with people looking at the camera, with recognizable faces, testifying social enjoyment and sense of identity. Finally, “Nature” pictures capture natural elements with no particular feature (such as species) but with an intermediate shot (differing from wide-open shots attributed to landscapes), expressing the appreciation of nature by people.</p>
