Data from: High detectability with low impact: optimising large PIT tracking systems for cave-dwelling bats

Emmi Van Harten, Terry Reardon, Linda Lumsden, Noel Meyers, Thomas Prowse, John Weyland & Ruth Lawrence
Passive integrated transponder (PIT) tag technology permits the ‘resighting’ of animals tagged for ecological research without the need for physical re-trapping. While this is effective if animals pass within centimetres of tag readers, short-distance detection capabilities have prevented the use of this technology with many species. To address this problem, we optimised a large (15 m-long) flexible antenna system to provide a c. 8 m2 vertical detection plane for detecting animals in flight. We installed...

Data from: Restoration potential of threatened ecosystem engineers increases with aridity: broad scale effects on soil nutrients and function

Orsi Decker, David J. Eldridge & Heloise Gibb
Species extinctions alter ecosystem services, and the magnitude of this impact is likely to change across environmental gradients. In Australia, soil-disturbing mammals that are now considered ecologically extinct are thought to be important ecosystem engineers. Previous studies have demonstrated microsite-level impacts of reintroduced soil-disturbing mammals on soil functions, but effects are yet to be tested across larger scales. Further, it is unclear how impacts vary across environmental gradients and if the restoration potential of reintroductions...

Data from: Maternal effects obscure condition-dependent sex allocation in changing environments

Amy Edwards, Elissa Cameron, Erik Wapstra & Joanne McEvoy
Climate change increases environmental fluctuations which thereby impact population demography. Species with temperature-dependent sex determination may experience more extreme sex ratio skews, but this has not been considered in species with chromosomally-determined sex. However, anticipatory maternal effects cause lifelong physiological changes impacting sex ratios. Here we show, in mice, that more sons were born to mothers in good condition when their breeding environment matched their gestational environment, consistent with theoretical predictions, but mothers in mismatched...

Abstraction through the Merger of Iconic Elements in Forming New Allographs: The Logogram 539

Sven Gronemeyer
One contributor to the calligraphic complexity of Classic Maya writing is the ability afforded by the script to create allographs. There are examples with multiple stages of extraction and simplification to create allographs. In order to create a unique graph, distinctive parts of the feline WAY icon are merged into the well-known allograph with its right half covered in jaguar fur, although both allographs represent the very same sign.
