Data Update – December 2017


Data publication from TERN repositories continues to grow and so too do the number of researchers utilising these great open-access resources and services.

This month we feature:

Who killed the wolf spider? A who-dunnart

First up this month we’re featuring four datasets on the predator-prey interactions and habitats of desert-dwelling marsupials and spiders, published in TERN’s AEKOS data portal by Tamara Potter of the University of Sydney’s Desert Ecology Research Group.  The data were collected by Tamara as part of a study into the lesser hairy-footed dunnart, a mouse-sized marsupial carnivore found in arid Australia, and its ravenous appetite for wolf-spiders.  Tamara’s work is uncovering the underlying mechanisms that drive this observed pattern of selective predation.

Direct observations of foraging wolf spiders and dunnarts


Data on the diet and predatory behaviour of wolf spiders (Lycosa spp.), the lesser hairy-footed dunnart (Sminthopsis youngsoni) and prowling spiders (Miturga spp.) in the Simpson Desert, Queensland, Australia.

Temporal coverage: 2016

Microhabitat selection by wolf spiders and dunnarts 

This dataset focuses on the overlap in the use of different microhabitats of wolf spiders (Lycosa spp.) and the lesser hairy-­footed dunnart (Sminthopsis youngsoni) in the Simpson Desert, Queensland, Australia.

Temporal coverage: 2016

Temporal activity of wolf spiders and dunnarts in the Simpson Desert 

Data on diel activity patterns of wolf spiders (Lycosa spp.) and the lesser hairy-footed dunnart (Sminthopsis youngsoni) collected by spotlight surveys and remote camera traps in the Simpson Desert, Queensland, Australia.

Temporal coverage: 2016

Availability of invertebrate prey for micro-carnivores


Data on the dietary patterns (food availability and selectivity) of wolf spiders (Lycosa spp.) and the lesser hairy-footed dunnart (Sminthopsis youngsoni) collected by invertebrate pitfall trapping in the Simpson Desert, Queensland, Australia.

Temporal coverage: 2016

Top End fauna data

TERN has recently published a series of long-term fauna monitoring datasets collected by the Northern Territory Government's Department of Environment and Natural Resources at the 220 permanent monitoring plots in Kakadu, Litchfield and Nitmiluk National Parks that form part of the Long Term Ecological Research Network's Three Parks Fire-Effects Plot Network. The program has been instrumental in detecting and reporting on the drastic decline of small mammals in these parks. These data provide information crucial to understanding how species are fairing, and elucidate the role of that fire and other factors have on changes in species and communities. Data collected as part of faunal surveys, bird counts, vertebrate trapping, nocturnal spotlighting and camera trapping are now freely available for download alongside data on fire incidence and severity, and vegetation.
