In hSDM: Hierarchical Bayesian Species Distribution Models

Data of presence-absence (from Latimer et al. 2006)

Description

Data come from a small region including 476 one minute by one minute grid cells. This region is a small corner of South Africa's Cape Floristic Region, and includes very high plant species diversity and a World Biosphere Reserve. The data frame can be used as an example for several functions in the hSDM package.

Format

datacells.Latimer2006 is a data frame with 476 observations (cells) on the following 9 variables.

y

the number of times the species was observed to be present in each cell

n

the number of visits or sample locations in each cell (which can be zero)

rough

elevational range or "roughness"

julmint

July minimum temperature

pptcv

interannual variation in precipitation

smdsum

summer soil moisture days

evi

enhanced vegetation or "greenness" index

ph1

percent acidic soil

num

number of neighbors of each cell, this is a sparse representation of the adjacency matrix for the subregion.
