2D
Two dimensional environmental space
3D
Three dimensional environmental space
BC
The background cloud (BC) is made up by a group of points in a 2D/3D environmental space (E). Each point has two or three values in E and a pair of geographic coordinates (longitude and latitude). In other words, the BC is mapping two or three geographic environmental variables in E.
CP
The convex polyhedron of the occurrence points in 2D or 3D E space, which can be used to estimate a species’ realized niche.
E/E space
Environmental space or niche space
ENM/SDM
Ecological niche modeling/Species distribution modeling
G/G space
Geographic space
N
Real or virtual species data set (i.e., niche model or occurrences), N(s) refers to several opened N in a scenario
Note:
N was names as G+ in the previous version. To avoid the garble with Geographic, we decided to change G+ to N. If you find any unreplaced text, figure or menus in both software and user manual, please tell me via huijieqiao@gmail.com. Thank you very much.
GDAL
Geospatial Data Abstraction Library, which is a library used to handle rasters in NicheA.
MVE
Minimum-volume ellipsoid, approach utilized to estimate a species’ fundamental niche
Selection
A white ellipsoid with six red points and a green point in NicheA’s virtual scenario, which is used to generate a virtual N by using the points inside of it from BC or another N.
