Indicative distribution map for Ecosystem Functional Group T6.2 Polar/alpine cliffs, screes, outcrops and lava flows
<p>This archive contains indicative distribution maps and profiles for <strong>T6.2 Polar/alpine cliffs, screes, outcrops and lava flows</strong>, a ecosystem functional group (EFG, level 3) of the <a href="https://global-ecosystems.org/">IUCN Global Ecosystem Typology</a> (v2.0). Please refer to Keith <em>et al.</em> (2020) for details.</p> <p>The descriptive profiles provide brief summaries of key ecological traits and processes, maps are indicative of global distribution patterns, and are not intended to represent fine-scale patterns. The maps show areas of the world containing major (value of 1, coloured red) or minor occurrences (value of 2, coloured yellow) of each ecosystem functional group. Minor occurrences are areas where an ecosystem functional group is scattered in patches within matrices of other ecosystem functional groups or where they occur in substantial areas, but only within a segment of a larger region. Given bounds of resolution and accuracy of source data, the maps should be used to query which EFG are likely to occur within areas, rather than which occur at particular point locations. Detailed methods and references for the maps are included in the profile (xml format).</p>
Darwin Core Archive: Santa Barbara Channel fish surveys at shallow outcrops
Nine nearshore, shallow-water rock outcrops, seven along the mainland and two off Anacapa Island, were monitored annually from 1995 to 2000. All locations were surveyed using scuba, and belt transects was were conducted at each site. These natural outcrops are geographically distributed across the Santa Barbara Channel providing opportunities for spatial and temporal comparisons between natural reef and oil/gas platforms. Fish surveys at platforms were conducted using scuba within a few days of these surveys at rock outcrops; the data can be viewed at: <link xlink:href="https://portal.lternet.edu/nis/mapbrowse?scope=edi&identifier=113">https://portal.lternet.edu/nis/mapbrowse?scope=edi&identifier=113</link> This scuba project was conducted and reported under a cooperative agreement (Agreement 1445-CA09-95-0836) between the U.

Data from: Abiotic and biotic drivers on tadpoles in seasonal rock pools of Western Ghats rock outcrops, India
<p>We assessed the influence of abiotic (pool size, monsoon progression) and biotic (predator abundances) factors on occurrence and abundance of three species of tadpoles by periodically monitoring rock pools in lateritic plateaus. The dataset generated from this study is published here. </p> <p>Species Coverage: <em>Euphlyctis jaladhara, Microhyla nilphamariensis, Polypedates maculatus</em>; four predator groups (Pisaurid Spiders, Crabs, Water Beetles, Dragonfly Larvae)</p> <p>Geographic Coverage: Devi Hasol plateu of Ratnagiri District, Maharashtra State, India. (16°44'–16°45'N; 73°25–73°27'E)</p> <p>Temporal Coverage: July, August, September (2022).</p> <p> </p> <p><strong>Methods:</strong></p> <p>Nighttime rock pool surveys were conducted for tadpoles of three species (<em>Euphlyctis jaladhara, Microhyla nilphamariensis, Polypedates maculatus</em>). Pools were monitored eight times during the study period between 1900–2300 hr, usually in clear weather, barring occasional rain incidences. The pool water was clear during all the observation occasions. For large (>1003 cm<sup>3</sup>) pools, the observer gently walked along the bank and scanned the pool to record all animals. Care was taken not to recount the same schools of tadpoles, and a red light was used while approaching the pool to avoid light disturbance. The observer enumerated tadpoles of the three species and their potential predators (fishing spiders, crabs, dragonfly larvae, and water beetles) by counting them using head and hand-held torch lights. Following microhabitat variables were recorded at four occasions: Pool maximum length and width (cm), water depth (cm) at three points, humus cover (%), submerged vegetation cover (%), and edge vegetation cover (%). The percentage covers of vegetation and humus were visually estimated. </p> <p> </p> <p><strong>Funding:</strong></p> <ol> <li>On the Edge (UK)</li> <li>The Habitats Trust (India)</li> <li>The Bombay Environmental Action Group (India)</li> </ol>

Weights for automatic two-dimensional bedrock fracture trace mapping from outcrop images
<p>This file contains weights for automatic two-dimensional bedrock fracture trace mapping. The weights have been trained on manually mapped traces (https://doi.org/10.5281/zenodo.7077574) that were digitized from UAV-acquired drone orthomosaics from along the shoreline of Loviisa, South-East Finland (https://doi.org/10.5281/zenodo.7077518). Code for automatic mapping and weights generation is available on GitHub (https://github.com/nialov/ALSA).</p> <p>Data is published as Hierarchical Data Format, version 5 (HDF5).</p> <p>The work in automatic mapping was done as part of a Geological Survey of<br> Finland project, Kallioperän Rikkonaisuus, during 2021-2022.</p>
