sample_explan_data {dynamicSDM}

Sample species occurrence records with associated dynamic explanatory variables

Description

A dataset containing a sample of the bird species, the red-billed quelea (Quelea quelea), distribution records from between 2002-2019 (GBIF 2021, GBIF 2022); generated pseudo-absence records, and associated extracted dynamic explanatory variables. The variables are as follows:

decimalLatitude

species occurrence record latitude.

decimalLongitude

species occurrence record longitude.

occurrenceStatus

species presence or absence character.

source

source of occurrence or pseudo-absence data point.

species

SAMP_EFFORT

total number of avian e-Bird sampling events within spatiotemporal buffer of occurrence record location and dates.

REL_SAMP_EFFORT
