Data from: Anchors and snorkels: heterochrony, development and form in functionally-constrained fossil crassatellid bivalves

Katie S. Collins, James S. Crampton, Helen L. Neil, Euan G. C. Smith, Michael F. Gazley & Michael Hannah
New growth-rate estimates for nine species from three genera of New Zealand Crassatellidae (Mollusca; Bivalvia), combined with existing morphometric ontogenetic descriptions, allow identification of heterochronic processes in the evolution of these genera. Both paedomorphosis (progenesis and neoteny) and peramorphosis (hypermorphosis and acceleration) have occurred within the clade. Overall, morphological variability and response to environmental pressure in this non-siphonate group is restricted by the interplay of anatomical and life-habit constraints. Stability in the substrate, predator avoidance,...

Data from: Toxicity and utilization of chemical weapons: does toxicity and venom utilization contribute to the formation of species communities?

Fabian L. Westermann, Iain S. McPherson, Tappy H. Jones, Lesley Milicich, Phillip J. Lester, Philip J. Lester & Tappey H. Jones
Toxicity and the utilization of venom are essential features in the ecology of many animal species and have been hypothesized to be important factors contributing to the assembly of communities through competitive interactions. Ants of the genus Monomorium utilize a variety of venom compositions, which have been reported to give them a competitive advantage. Here, we investigate two pairs of Monomorium species, which differ in the structural compositions of their venom and their co-occurrence patterns...

Data from: The role of scent marking in mate selection by female pumas (Puma concolor)

Maximilian L. Allen, Heiko U. Wittmer, Paul Houghtaling, Justine A. Smith, L. Mark Elbroch, Christopher C. Wilmers & Justine Smith
Mate selection influences individual fitness, is often based on complex cues and behaviours, and can be difficult to study in solitary species including carnivores. We used motion-triggered cameras at 29 community scrapes (i.e. scent marking locations used by multiple individuals) and home range data from 39 GPS-collared pumas (Puma concolor) to assess the relevance of communication behaviours for mate selection by female pumas in California. Female pumas visited community scrapes irregularly and visitation bouts appeared...

Data from: Patterns of niche filling and expansion across the invaded ranges of an Australian lizard

Reid Tingley, Michael B. Thompson, Stephen Hartley & David G. Chapple
Studies of realized niche shifts in alien species typically ignore the potential effects of intraspecific niche variation and different invaded-range environments on niche lability. We incorporate our detailed knowledge of the native-range source populations and global introduction history of the delicate skink Lampropholis delicata to examine intraspecific variation in realized niche expansion and unfilling, and investigate how alternative niche modelling approaches are affected by that variation. We analyzed the realized niche dynamics of L. delicata...

Data from: Having a lot of a good thing: multiple important group memberships as a source of self-esteem

Jolanda Jetten, Nyla R. Branscombe, S. Alexander Haslam, Catherine Haslam, Tegan Cruwys, Janelle M. Jones, Lijuan Cui, Genevieve Dingle, James Liu, Sean Murphy, Anh Thai, Zoe Walter & Airong Zhang
Membership in important social groups can promote a positive identity. We propose and test an identity resource model in which personal self-esteem is boosted by membership in additional important social groups. Belonging to multiple important group memberships predicts personal self-esteem in children (Study 1a), older adults (Study 1b), and former residents of a homeless shelter (Study 1c). Study 2 shows that the effects of multiple important group memberships on personal self-esteem are not reducible to...

Data from: Emerging patterns of genetic variation in the New Zealand endemic scallop Pecten novaezelandiae

Catarina N. S. Silva & Jonathan P. A. Gardner
Both historical and contemporary processes influence the genetic structure of species, but the relative roles of such processes are still difficult to access. Population genetic studies of species with recent evolutionary histories such as the New Zealand endemic scallop Pecten novaezelandiae (<1 Ma) permit testing of the effects of recent processes affecting gene flow and shaping genetic structure. In addition, studies encompassing the entire distributional range of species can provide insight into colonization processes. Analyses...

Data from: Isolation by resistance across a complex coral reef seascape

Luke Thomas, W. Jason Kennington, Michael Stat, Shaun P. Wilkinson, Jonathan T. Kool & Gary A. Kendrick
A detailed understanding of the genetic structure of populations and an accurate interpretation of processes driving contemporary patterns of gene flow are fundamental to successful spatial conservation management. The field of seascape genetics seeks to incorporate environmental variables and processes into analyses of population genetic data to improve our understanding of forces driving genetic divergence in the marine environment. Information about barriers to gene flow (such as ocean currents) is used to define a resistance...

Data from: Evidence for Bergmann's rule and not allopatric subspeciation in the threatened kaka (Nestor meridionalis)

Nic Dussex, James Sainsbury, Ron Moorhouse, Ian G. Jamieson & Bruce C. Robertson
Species of conservation concern characterized by small and declining populations greatly benefit from proactive management approaches such as population translocations. Because they often show intra-specific genetic and phenotypic variation, which can result from drift or differential selective pressures between habitats, understanding the distribution of such variation and its underlying processes is a prerequisite to develop effective management guidelines. Indeed, translocations among genetically differentiated populations potentially locally adapted are discouraged in order to avoid outbreeding depression,...
