Is the future already here? The impact of climate change on the distribution of the eastern coral snake (Micrurus fulvius)

PMCID: 5935076
PMID: 29736330
DOI: 10.7717/peerj.4647

[…] on to background selection, note that spatial filtering will further reduce bias associated with non-systematic sampling. Therefore, the Spatially Rarefy Occurrence Data for SDMs tool set within the SDMtoolbox ( was used to classify and spatially filter the climate variables into different homogenous areas and reduce the number of points clustered around these homogenous zo […]


Climate change versus deforestation: Implications for tree species distribution in the dry forests of southern Ecuador

PLoS One
PMCID: 5739474
PMID: 29267357
DOI: 10.1371/journal.pone.0190092

[…] uted to deforestation and climate change, we calculated the core distributional shifts (i.e., area centroids) for each species according to two time frames: 2008–2014 and 2014–2050. For this, we used SDMtoolbox [], a python-based GIS toolkit for automating analyses in ecology and species distribution models. This analysis reduces the distribution area to a single point and creates a line that repr […]


Ice age unfrozen: severe effect of the last interglacial, not glacial, climate change on East Asian avifauna

BMC Evol Biol
PMCID: 5719578
PMID: 29212454
DOI: 10.1186/s12862-017-1100-2
call_split See protocol

[…] known distributions were removed. To avoid spatial autocorrelation, the retained records were then rarefied at a 5-km spatial resolution under a south Asian continent equidistant conic projection in SDMtoolbox 1.1c [] (see dataset in Additional file ), roughly equivalent to the resolution of climatic layers (e.g. 2.5 arc-minute resolution). Climate grids for the present and LGM (under the Communi […]


Schistosoma japonicum transmission risk maps at present and under climate change in mainland China

PLoS Negl Trop Dis
PMCID: 5659800
PMID: 29040273
DOI: 10.1371/journal.pntd.0006021
call_split See protocol

[…] les was assessed by a jackknife analysis of variable importance in Maxent ([], see below for Maxent detail), and unimportant variables were discarded. Highly correlated variables were then removed in SDMtoolbox, a python-based GIS toolkit for spatial analysis []. Eight variables () that showed ecological relevance (regularized training gain >0.14) and low correlation with other variables (Pearson […]


Combining dispersal, landscape connectivity and habitat suitability to assess climate induced changes in the distribution of Cunningham’s skink, Egernia cunninghami

PLoS One
PMCID: 5584964
PMID: 28873398
DOI: 10.1371/journal.pone.0184193

[…] occupied cells that were projected to become unsuitable to the nearest cells that became or remained suitable in the subsequent time horizon were modeled using the landscape connectivity model in the SDMtoolbox package [], implemented in ArcGIS v10.2.1 (ESRI Inc., Redlands CA, USA, 2013). Given computational processes and software challenges of modeling connectivity at fine resolution over large s […]


Dispersal corridors for plant species in the Poyang Lake Basin of southeast China identified by integration of phylogeographic and geospatial data

Ecol Evol
PMCID: 5528243
PMID: 28770054
DOI: 10.1002/ece3.2999

[…] For each species, the dispersal corridors at the present and at the LGM were mapped by applying the CLCP method using SDMtoolbox (Brown, ) in ArcGIS 9.3 (Environmental Systems Research Institute, Inc., Redlands, CA). Given a chloroplast haplotype network, we generated a population connectivity map by summing the leas […]
