Data from: Complexity of the genetic basis of aging in nature revealed by a clinal study of lifespan and methuselah, a gene for aging, in Drosophila from eastern Australia.

Carla M. Sgrò, Belinda Van Heerwaarden, Vanessa Kellermann, Choon Wei Wee, Ary A. Hoffmann & Siu Fai Lee
Clinal studies are a powerful tool for understanding the genetic basis of climatic adaptation. However, while clines in quantitative traits and genetic polymorphisms have been observed within and across continents, few studies have attempted to demonstrate direct links between them. The gene methuselah in Drosophila has been shown to have a major effect on stress response and longevity phenotypes based largely on laboratory studies of induced mutations in the mth gene. Clinal patterns in the...

Data from: Night warming on hot days produces novel impacts on development, survival and reproduction in a small arthropod

Fei Zhao, Wei Zhang, Ary A. Hoffmann & Chun-Sen Ma
1. An asymmetric increase of nighttime temperatures on hot days is one of the main features of global climate change. But the biological effects of an increased nighttime temperature combined with high daytime temperature are unclear. 2. We used six thermal regimens to simulate nighttime temperatures on hot days and investigated the effects of night warming on life history traits of the English grain aphid Sitobion avenae. Experimental temperatures fluctuated in continuous diurnal cycles, increasing...

Data from: Sex-linked and autosomal microsatellites provide new insights into island populations of the tammar wallaby

Anna J. MacDonald, Nancy N. FitzSimmons, Brian Chambers, Marilyn B. Renfree & Stephen D. Sarre
The emerging availability of microsatellite markers from mammalian sex chromosomes provides opportunities to investigate both male- and female-mediated gene flow in wild populations, identifying patterns not apparent from the analysis of autosomal markers alone. Tammar wallabies (Macropus eugenii), once spread over the southern mainland, have been isolated on several islands off the Western Australian and South Australian coastlines for between 10 000 and 13 000 years. Here, we combine analyses of autosomal, Y-linked and X-linked...

Data from: A systematic review of methods for studying consumer health YouTube videos, with implications for systematic reviews

Margaret Sampson, Jordi Cumber, Claudia Li, Catherine M. Pound, Ann Fuller, Denise M. Harrison & Denise Harrison
Background. YouTube is an increasingly important medium for consumer health information – with content provided by healthcare professionals, government and non-government organizations, industry, and consumers themselves. It is a rapidly developing area of study for healthcare researchers. We examine the methods used in reviews of YouTube consumer health videos to identify trends and best practices. Methods and Materials. Published reviews of consumer-oriented health-related YouTube videos were identified through PubMed. Data extracted from these studies included...

Data from: Odour cues influence predation risk at artificial bat roosts in urban bushland

Caragh Threlfall, Bradley Law & Peter B. Banks
Odours that accumulate from roosting can attract predators and increase predation risk. Consequently, selection should favour strategies that allow prey to evade detection by predators, including changing roosts. Insectivorous bats that roost in tree hollows regularly switch roosts and roost in different sized groups: strategies that would alter the accumulation of roost odours and are hypothesized to reduce predation risk. We experimentally manipulated the amount and refresh rate of roosting odour cues at 90 artificial...

Data from: Balancing genetic uniqueness and genetic variation in determining conservation and translocation strategies: a comprehensive case study of threatened dwarf galaxias, Galaxiella pusilla (Mack) (Pisces: Galaxiidae)

Rhys A. Coleman, Andrew R. Weeks & Ary A. Hoffmann
Genetic markers are widely used to define and manage populations of threatened species based on the notion that populations with unique lineages of mtDNA and well-differentiated nuclear marker frequencies should be treated separately. However a danger of this approach is that genetic uniqueness might be emphasized at the cost of genetic diversity, which is essential for adaptation and is potentially boosted by mixing geographically separate populations. Here we re-explore the issue of defining management units,...

Data from: Polymorphism in the neurofibromin gene, Nf1, is associated with antagonistic selection on wing size and development time in Drosophila melanogaster

Siu Fai Lee, Ying Chen Eyre-Walker, Caroline Reuter, Giovanna Vinti, Rahul V. Rane, Lea Rako, Linda Partridge & Ary A. Hoffmann
In many invertebrates, body size shows genetically based clines, with size increasing in colder climates. Large body size is typically associated with prolonged development times. We consider variation in the CNS-specific gene neurofibromin 1 (Nf1) and its association with body size and development time. We identified two major Nf1 haplotypes in natural populations, Nf1-insertion-A and Nf1-deletion-G. These haplotypes are characterized by a 45-base insertion/deletion (INDEL) in Nf1 intron 2 and an A/G synonymous substitution (locus...

Data from: Discrete colour polymorphism in the tawny dragon lizard (Ctenophorus decresii) and differences in signal conspicuousness among morphs

Luisa C. Teasdale, Martin Stevens & Devi Stuart-Fox
Intraspecific colour variation is common in nature and can vary from the coexistence of discrete colour variants in polymorphic species to continuous variation. Whether coloration is continuous or discrete is often ambiguous and many species exhibit a combination of the two. The nature of the variation (discrete or continuous) has implications for both the genetic basis of the colour variation and the evolutionary processes generating and maintaining it. Consequently, it is important to qualify the...

Data from: Spatio-temporal changes in the structure of an Australian frog hybrid zone: a 40 year perspective

Katie Louise Smith, Joshua Miles Hale, Laurène Gay, Michael R. Kearney, Jeremy J. Austin, Kirsten M. Parris, Jane Melville & Michael Kearney
Spatio-temporal studies of hybrid zones provide an opportunity to test evolutionary hypotheses of hybrid zone maintenance and movement. We conducted a landscape genetics study on a classic hybrid zone of the south-eastern Australian frogs, Litoria ewingii and L. paraewingi. This hybrid zone has been comprehensively studied since the 1960s, providing the unique opportunity to directly assess changes in hybrid zone structure across time. We compared both mtDNA and male advertisement call data from two time...
