Recent expansion of oil palm agriculture has resulted in loss of forest habitat and forest-dependent species. However, large numbers of species – particularly insects – can persist within plantations. This study focuses on Odonata (dragonflies and damselflies): a charismatic indicator taxon, and a potentially valuable pest control agent. We surveyed adult Odonata populations biannually over three years within an industrial oil palm plantation in Sumatra, Indonesia. We assessed the effects of rainfall (including an El...

Data from: Malaysian weedy rice shows its true stripes: wild Oryza and elite rice cultivars shape agricultural weed evolution in Southeast Asia

Beng-Kah Song, Tse-Seng Chuah, Sheh May Tam & Kenneth M. Olsen
Weedy rice is a close relative of domesticated rice (Oryza sativa) that competes aggressively with the crop and limits rice productivity worldwide. Most genetic studies of weedy rice have focused on populations in regions where no reproductively compatible wild Oryza species occur (North America, Europe, northern Asia). Here we examined the population genetics of weedy rice in Malaysia, where wild rice (O. rufipogon) can be found growing in close proximity to cultivated and weedy rice....

Mutations in the tail domain of MYH3 contributes to atrial septal defect

Sathiya Maran
Atrial septal defect (ASD) is one of the most common congenital heart defects (CHDs) diagnosed in children. Sarcomeric genes has been attributed to ASD and knockdown of MYH3 functionally homologues gene in chick models indicated abnormal atrial septal development. Here, we report for the first time, a case-control study investigating the role of MYH3 among non-syndromic ASD patients in contributing to septal development. Four amplicons which will amplifies the 40 kb MYH3 were designed and...

Data from: Little white lies: pericarp color provides insights into the origins and evolution of Southeast Asian weedy rice

Yongxia Cui, Beng Kah Song, Lin-Feng Li, Ya-Ling Li, Zhongyun Huang, Ana L. Caicedo, Yulin Jia & Kenneth M. Olsen
Weedy rice is a conspecific form of cultivated rice (Oryza sativa L.) that infests rice fields and results in severe crop losses. Weed strains in different world regions appear to have originated multiple times from different domesticated and/or wild rice progenitors. In the case of Malaysian weedy rice, a multiple-origin model has been proposed based on neutral markers and analyses of domestication genes for hull color and seed shattering. Here we examined variation in pericarp...

Data from: Sacrificial males: the potential role of copulation and predation in contributing to copepod sex-skewed ratios

Predation is thought to play a selective role in the emergence of behavioural traits in prey. Differences in behaviour between prey demographics may, therefore, be driven by predation with select components of the population being less vulnerable to predators. While under controlled conditions prey demography has been shown to have consequences for predation success, investigations linking these implications to natural prey population demographics are scarce. Here we assess predator-prey dynamics between notonectid predators (backswimmers) and...

Data from: Signatures of polygenic adaptation associated with climate across the range of a threatened fish species with high genetic connectivity

Katherine A. Harrisson, Stephen J. Amish, Alexandra Pavlova, Shawn R. Narum, Marina Telonis-Scott, Meaghan L. Rourke, Jarod Lyon, Zeb Tonkin, Dean M. Gilligan, Brett A. Ingram, Mark Lintermans, Han Ming Gan, Christopher M. Austin, Gordon Luikart & Paul Sunnucks
Adaptive differences across species’ ranges can have important implications for population persistence and conservation management decisions. Despite advances in genomic technologies, detecting adaptive variation in natural populations remains challenging. Key challenges in gene-environment association studies involve distinguishing the effects of drift from those of selection, and identifying subtle signatures of polygenic adaptation. We used paired-end restriction-site associated-DNA sequencing data (6605 biallelic single nucleotide polymorphisms; SNPs) to examine population structure and test for signatures of adaptation...

Data from: Climate-driven mitochondrial selection: a test in Australian songbirds

Annika M. Lamb, Han Ming Gan, Chris Greening, Leo Joseph, Yin P. Lee, Alejandra Morán-Ordóñez & Paul Sunnucks
Diversifying selection between populations that inhabit different environments can promote lineage divergence within species and ultimately drive speciation. The mitochondrial genome (mitogenome) encodes essential proteins of the oxidative phosphorylation (OXPHOS) system and can be a strong target for climate-driven selection (i.e. associated with inhabiting different climates). We investigated whether Pleistocene climate changes drove mitochondrial selection and evolution within Australian birds. First, using phylogeographic analyses of the mitochondrial ND2 gene for 17 songbird species, we identified...
