Data from: Tree-hugging koalas demonstrate a novel thermoregulatory mechanism for arboreal mammals

How climate impacts organisms depends not only on their physiology, but also whether they can buffer themselves against climate variability via their behaviour. One of the way species can withstand hot temperatures is by seeking out cool microclimates, but only if their habitat provides such refugia. Here, we describe a novel thermoregulatory strategy in an arboreal mammal, the koala Phascolarctos cinereus. During hot weather, koalas enhanced conductive heat loss by seeking out and resting against...

Data from: Nonrandom, diversifying processes are disproportionately strong in the smallest size classes of a tropical forest

Peter T. Green, Kyle E. Harms & Joseph H. Connell
A variety of ecological processes influence diversity and species composition in natural communities. Most of these processes, whether abiotic or biotic, differentially filter individuals from birth to death, thereby altering species’ relative abundances. Nonrandom outcomes could accrue throughout ontogeny, or the processes that generate them could be particularly influential at certain stages. One long-standing paradigm in tropical forest ecology holds that patterns of relative abundance among mature trees are largely set by processes operating at...

Data from: Genetic diversity and population structure of the threatened freshwater catfish, Tandanus tandanus, in Victoria, Australia

Erin Hill, Brett A. Ingram, Meaghan Rourke, John Mitchell & Jan M. Strugnell
In Australia, many species of freshwater fish have rapidly declined following European settlement in the late eighteenth century. The freshwater catfish (Tandanus tandanus) is listed as threatened in Victoria and accordingly, broodstock management and a captive breeding program to facilitate the reintroduction of hatchery bred fish into depleted populations have been suggested. Little work has been conducted on Victorian populations of T. tandanus, despite its threatened status. This study assessed the genetic diversity and genetic...

Data from: Evolutionary origins of a bioactive peptide buried within preproalbumin

Alysha G. Elliott, Christina Delay, Huanle Liu, Zaiyang Phua, K. Johan Rosengren, Aurélie H. Benfield, Jose L. Panero, Michelle L. Colgrave, Achala S. Jayasena, Kerry M. Dunse, Marilyn A. Anderson, Edward E. Schilling, Daniel Ortiz-Barrientos, David J. Craik & Joshua S. Mylne
The de novo evolution of proteins is now considered a frequented route for biological innovation, but the genetic and biochemical processes that lead to each newly created protein are often poorly documented. The common sunflower (Helianthus annuus) contains the unusual gene PawS1 (Preproalbumin with SFTI-1) that encodes a precursor for seed storage albumin; however, in a region usually discarded during albumin maturation, its sequence is matured into SFTI-1, a protease-inhibiting cyclic peptide with a motif...
