Data package contains a dataset of distances(m) of 15 dyads generated from GPS collar data of 6 female savannah elephants as they were being released from semi-captivity to the wild in Okavango Delta, Botswana from November 1st, 2021-November 29th,2023. The dataset is provided as part the manuscript `Dyadic distance in African savannah elephants (Loxotonda africana) increases during release from semi-captivity to the wild`.
Discontinued Vegetation Line-Intercept Transects in Transition Zones at the Sevilleta National Wildlife Refuge, New Mexico (1989-1998)
The line-intercept transects included in this data set have been discontinued. These transects were installed to evaluate temporal and spatial dynamics in vegetation transition zones (e.g.black grama grassland/creosote shrubland) at one centimeter resolution. Each study site originally contained four 400 m transects, representing total coverage of 1 sq km. The transects were placed along a roughly north/south azimuth. The northwestern and southwestern transects were 100 meters from the western edge of the 1 sq km study area and the northeastern and southeastern transects were 100 m from the eastern edge, providing 800 meters between the eastern and western transects. The northeastern and northwestern transects began to the north and, after an interval of 200 meters, the southeastern and northeastern transects began, terminating at the southern edge of the study area. Ongoing line-intercept transect data for transect 1, which continues to be sampled at both Deep Well and Five Points, can be found in SEV004.
End of Year Biomass in marsh transition plots in Upper Phillips Creek marsh 1999-2014
Background: Brinson et al. (1995) developed a model representing the change that occurs in ecosystem state (or habitat type) along the shorezone, from the forest -> high marsh -> low marsh -> mud flat, in response to the increased inundation caused by rising sea-level. They suggested that a seaward shift in ecosystem state is largely dependent on local slope and sediment supply. The states are associated with the dominant vegetation found within each. The most seaward (lowest in elevation) state is the mud flat. It is frequently inundated by tide and typically supports algal species. The next landward state is the mineral low marsh; it is dominated by Spartina alterniflora and is typically flooded at high tide. Sediments here may be largely mineral in origin. The next landward state is the high marsh; it may be dominated by S. patens, Distichlis spicata, and Juncus roemerianus. It is occasionally inundated by high tides and the soil is usually organic. The transition zone between the high marsh and the forest is typically dominated by Iva frutescens, Baccharis hamifolia, and Juniperus virginiana. It is only inundated during severe storm surges. The forest may be dominated by either pines or hardwoods and is again flooded with sea water only by storm surges. Brinson, M.M., R.R. Christian, and L.K. Blum. 1995.

Carbon stocks in forests transitioning to salt marsh at four sites in the Chesapeake Bay region, 2019
This data set contains measurements of carbon stocks across five vegetation zones that comprise the marsh-forest boundary at sites within Virginia (Goodwin Island and Phillips Creek) and Maryland (Monie Bay and Moneystump/Blackwater). Carbon stocks were measured from soil samples and allometric measurements collected in June-July of 2019. Soil salinity, elevation, and GPS location data are similarly included in this data set.
