Desert Ecology Plot Network: Mammal, Reptile and Vegetation Data Associated with Weather, Simpson Desert, Western Queensland, Australia, 1990–2011

This data package is a derivative comprising of a subset of data from four existing data packages: • Weather Data (daily and monthly), Simpson Desert, Western Queensland, 1995–2011 (http://www.ltern.org.au/knb/metacat/ltern.48/html) • Vegetation Plot-data, Simpson Desert, Western Queensland, 1990–2011 (http://www.ltern.org.au/knb/metacat/ltern.44/html) • Mammal Abundance Plot-data, Simpson Desert, Western Queensland, 1990–2011 (http://www.ltern.org.au/knb/metacat/ltern.37/html) • Reptile Abundance Plot-data, Simpson Desert, Western Queensland, 1990–2011 (http://www.ltern.org.au/knb/metacat/ltern.42/html) These data are used to produce the graphs found in figure 10.25 on pages 411–412 in Lindenmayer et. al 2014, Biodiversity and Environmental Change: Monitoring Challenges and Direction. They have been combined to illustrate the vegetation and vertebrate response to weather patterns, and the interaction between predator and prey during these cycles. The data includes: • monthly rainfall data for automatic weather stations situated at 13 sites separated by distances of between 5 and 80 km. • percentage ground cover of spinifex (Triodia basedowii) • mammal abundance data for two species of rodent (Spinifex Hopping-mouse & Sandy Inland Mouse) who feed on spinifex seed • mammal abundance data for the Lesser Hairy-footed Dunnart (an insectivore) • mammal abundance data for the Brush-tailed Mulgara, a predator who feeds on the Spinifex Hopping-mouse & Sandy Inland Mouse • reptile abundance data for the Military Dragon • reptile abundance data for the Central Netted Dragon Vegetation attributes were recorded in an area occupying 2.5 m radius around six traps on each trapping grid and have been aggregated to grid level data. Weather data is collected from automatic weather stations situated at 13 sites separated by distances of between 5 and 80 km. Capture data for a specified duration of trapping nights (usually 3 night session) in the Simpson Desert, Western Queensland. Captured mammal and reptile fauna were identified and recaptures during the same session were removed (i.e. individuals were only counted once). Date, site and grid number were recorded for all captures, and captured animals were also marked by a unique ear notch prior to their release to identify recaptures. The network program uses a core of 12 sites which are sampled every April-May. The trapping survey aims to quantitatively track long-term shifts in biodiversity and ecological processes in relation to key drivers, including unpredictable rainfall and droughts, fire, feral predators and grazing.
