Savanna plant and soil carbon data from different burn seasons and histories across Mole National Park, Ghana
<p>Aboveground plant pool and belowground (soil plus root) carbon data for a space-for-time substitution survey of different burn seasons and histories across Mole National Park, Ghana. Carbon data was collected to determine the impact of unintentional late growing season wildfires on carbon storage in a protected area dominated by early growing season prescribed burning land management. The methodology and findings from the study are detailed in the below publication:</p> <p>Awuah J, Smith SW, Speed JDM, Graae BJ. 2022. Can seasonal fire management reduce the risk of carbon loss from wildfires in a protected Guinea savanna? Ecosphere, e4283. https://doi. 88 org/10.1002/ecs2.4283 </p> <p>This data repository contains the following data (and descriptive metadata): </p> <p>(1) Study_site_coordinates: locations for 28 sites surveyed in 2016 as part of an ecosystem carbon stock assessment</p> <p>(2) Aboveground_carbon: aboveground tree, shrub, herbaceous vegetation, deadwood and litter carbon stocks estimated from either destructive biomass sampling or allometric equations. Aboveground carbon data are presented per site. </p> <p>(3) LOI_to_carbon_conversion: a subset of soil samples were analysed for both loss on ignition (LOI) and automated dry combustion using an elemental analyser, the latter more accurate for carbon determination and used to correct LOI values. </p> <p>(4) Belowground_carbon: combined soil and root carbon collected collected to a maximum depth of 17 cm, and split into four soil layers (0-2 cm, 2-7 cm, 7-12 cm and 12-17 cm). </p> <p>MCD14DL MODIS Active Fire Detections data used to defined different burn seasons and histories for sites has not been uploaded and is freely available from online sources detailed in the journal article. </p>
Dietary data of an anuran assemblage from Yasuní National Park
<p class="MsoNormal"><span>This dataset describes the diet of a highly diverse tropical anuran assemblage. We report the diet composition of 35 species collected at Yasuní National Park, b</span>ased on the examination of the gastrointestinal contents of 396 frog specimens available in the Museo de Zoología (QCAZ) of Pontificia Universidad Católica del Ecuador. Anuran species belong to six families: Aromobatidae, Bufonidae, Dendrobatidae, Hylidae, Leptodactylidae, and Strabomantidae. We were able to identify 4,085 prey items that were classified into 71 categories. We present information on anuran-prey interactions, prey-items volume, and anuran specimens' associated data. This data set contributes to understanding the trophic ecology of anuran species and their role in tropical ecosystems.</p>
King Colobus and Western Red Colobus of Taï National Park - microsatellite dataset
<p><strong>Abstract:</strong></p> <p>We compared the genetic patterns - genetic diversity, population structure, and demographic history - of two African colobine species - King Colobus (<em>Colobus polykomos</em>) and Western Red Colobus (<em>Piliocolobus badius</em>) - in Taï National Park (TNP), Ivory Coast, and Cantanhez Forests National Park (CFNP), Guinea-Bissau, using a dataset of microsatellite loci. While TNP is the largest and best preserved forest of West Africa, CFNP is highly fragmented. Thus, these two forests provide the opportunity of studying the impact of forest status on the maintenance of these species' evolutionary potential.</p> <p>CFNP colobines showed very low genetic diversity, while the populations in TNP still maintain high levels of genetic diversity. A strong signal of population decline was and we found no clear signal of population decrease in Western red colobus and a limited decrease in King colobus. These results suggest larger and historically more stable populations in TNP compared to CFNP. We cannot exclude the possibility that the demographic effects resulting from the recent increase of bushmeat hunting are not yet detectable in TNP using genetic data. Nevertheless, the fact that the TNP colobus populations are highly genetically diverse and maintain large effective population sizes suggests that well-preserved forests are crucial for the maintenance of populations, species and probably for the evolutionary potential in colobines.</p> <p> </p> <p><strong>Methods:</strong></p> <p>Blood-derived DNA samples of eight King Colobus (<em>Colobus polykomos</em>) and 20 Western Red Colobus (<em>Piliocolobus badius</em>) were genotyped for eleven and ten, respectively, human-derived nuclear microsatellite loci. Loci were amplified by Polymerase Chain Reaction (PCR), following the protocol optimised by Minhós <em>et al.</em> (2013). PCR products were analysed using an ABI 3130XL Automatic Sequencer at the Genomics Unit of Instituto Gulbenkian de Ciência, Portugal. Alleles were scored using GeneMapper® Software version 4.1 (Applied Biosystems). Each locus was genotyped up to three times per sample and two independent observers scored the genotypes. Genotypes were considered as heterozygous after each allele was observed in at least two independent PCR reactions. This dataset presents the consensus genotypes obtained for each individual at each locus. No GPS data are available for this dataset, although all individuals are known to come from Taï National Park, Ivory Coast.</p> <p> </p> <p><strong>Usage notes:</strong></p> <p>The dataset corresponds to two CSV files - one for King Colobus (<em>Colobus polykomos</em>) and another for Western Red Colobus (<em>Piliocolobus badius</em>). The header shows microsatellite names (2 columns per microsatellite, as these are diploid individuals) and each subsequent row corresponds to an individual. The first column exhibits the codes of the individuals. Missing data is coded as 0.</p>
Bell Caves at Beit Guvrin National Park
The man-made Bell Caves in Beit Guvrin, Israel served as quarries that supplied building materials to the cities of the coastal plain and Beit Guvrin during the 7th-10th centuries CE. The media source for this 'proof-of-principle' model was a 360 video camera used in a walking tour. 500, 360-degree equirectangular images were extracted from the video, each image then being run through the Flexify v2 Photoshop plugin, with '12 views' as the output projection. The output of the Flexify plugin is a single large image comprising of 12 rectilinear overlapping views side by side, and spanning the full 360 degrees. The Flexify plugin output was then split into 12 separate images using, for example Photoscape or XnViewMP. These (now 6000) images were used as the actual input source for the model generation. Motion blur within the images, caused by the non stationary video camera being employed in low lighting conditions (causing relatively long camera shutter speeds), has reduced the overall resolution of the model.

Grand Canyon National Park 3D Aerial Map
Map of the Grand Canyon National Park in Arizona. Featuring the Kaibab Plateau, Colorado River, and Little Colorado River Gorge. The Grand Canyon is the second-most visited National Park in the United States, at visitation of around 6 million people each year. The South Rim of the park is around 7,000 feet in elevation, while the North Rim is 8,000 to nearly 9,000 feet. From the Grand Canyon you can often see over 100 miles in many directions, with Flagstaff's San Francisco Peaks to the South, and Navajo Mountain in Utah to the Northeast. The Canyon is home to many Native American tribes, and thousands of archaeology sites are found from the rim to the river. Among notable archaeological sites is the Unkar Delta, with of 52 excavated sites from Ancestral Puebloan people (Hisatsinom) who lived there 800–1200 years ago, planting on the delta and growing corn, squash, beans. Enjoy this free map of one of my favorite places in the world, and just in my "backyard". -Nate Loper Source: Objaverse 1.0 / Sketchfab
