Data from: Technical note: rapid image-based field methods improve the quantification of termite mound structures and greenhouse-gas fluxes

Philipp A. Nauer, Eleonora Chiri, David De Souza, Lindsay B. Hutley & Stefan K. Arndt
Termite mounds (TMs) mediate biogeochemical processes with global relevance, such as turnover of the important greenhouse gas methane (CH4). However, the complex internal and external morphology of TMs impede an accurate quantitative description. Here we present two novel field methods, photogrammetry (PG) and cross-section image analysis, to quantify TM external and internal mound structure of 29 TMs of three termite species. Photogrammetry was used to measure epigeal volume (VE), surface area (AE) and mound basal...

Data from: Pervasive admixture between eucalypt species has consequences for conservation and assisted migration

Brenton Von Takach Dukai, Cameron Jack, Justin Borevitz, David B. Lindenmayer & Sam C. Banks
Conservation management often uses information on genetic population structure to assess the importance of local provenancing for ecological restoration and reintroduction programs. For species that do not exhibit complete reproductive isolation, the estimation of population genetic parameters may be influenced by the extent of admixture. Therefore, to avoid perverse outcomes for conservation, genetically-informed management strategies must determine whether hybridisation between species is relevant, and the extent to which observed population genetic patterns are shaped by...

Data from: The thermal dependency of locomotor performance evolves rapidly within an invasive species

Georgia K. Kosmala, Gregory P. Brown, Keith A. Christian, Cameron M. Hudson & Richard Shine
Biological invasions can stimulate rapid shifts in organismal performance, via both plasticity and adaptation. We can distinguish between these two proximate mechanisms by rearing offspring from populations under identical conditions, and measuring their locomotor abilities in standardized trials. We collected adult cane toads (Rhinella marina) from invasive populations that inhabit regions of Australia with different climatic conditions. We bred those toads, and raised their offspring under common-garden conditions before testing their locomotor performance. At high...

Data from: An experimental test of whether pyrodiversity promotes mammal diversity in a northern Australian savanna

Hugh F. Davies, Michael A. McCarthy, Willie Rioli, José Puruntatameri, Willie Roberts, Colin Kerinaiua, Vivian Kerinauia, Kim Brooks Womatakimi, Alan N. Andersen & Brett P. Murphy
1. The increasing awareness that a fire regime that promotes biodiversity in one system can threaten biodiversity in another has resulted in a shift away from fire management based on vague notions of maximising pyrodiversity, towards determining the optimal fire regime based on the demonstrated requirements of target species. 2. We utilised a long-running, replicated fire experiment on Melville Island, the largest island off the northern Australian coast, to test the importance of pyrodiversity for...

Data from: Human disturbance promotes herbivory by leaf-cutting ants in the Caatinga dry forest

Felipe F. S. Siqueira, José Domingos Ribeiro-Neto, Marcelo Tabarelli, Alan N. Andersen, Rainer Wirth & Inara R. Leal
Anthropogenic disturbances are known to modify plant-animal interactions such as those involving the leaf-cutting ants, the most voracious and proliferating herbivore across human-modified landscapes in the Neotropics. Here we evaluate the effect of chronic anthropogenic disturbance (e.g. firewood collection, livestock grazing) and vegetation seasonality on foraging area, foliage availability in the foraging area, leaf consumption, and herbivory rate of the leaf-cutting ant Atta opaciceps in the semi-arid Caatinga, a mosaic of dry forest and scrub...

Data from: Insular biogeographic origins and high phylogenetic distinctiveness for a recently depleted lizard fauna from Christmas Island, Australia

Paul M. Oliver, Mozes P.K. Blom, Harold G. Cogger, Robert N. Fisher, Jonathan Q. Richmond, John C.Z. Woinarski & John C. Z. Woinarski
Striking faunal turnover across Asia and Australasia, most famously along the eastern edge of the Sunda Shelf or ‘Wallace’s Line’, has been a focus of biogeographic research for over 150 years. Here we investigate the origins of a highly threatened endemic lizard fauna (4 species) on Christmas Island. Despite occurring less 350 km south of the Sunda Shelf, this fauna mostly comprises species from clades centred on the more distant regions of Wallacea, the Pacific...
