Data from: Transgenerational plasticity of reproduction depends on rate of warming across generations

Jennifer M. Donelson, Marian Wong, David J. Booth & Philip L. Munday
Predicting the impacts of climate change to biological systems requires an understanding of the ability for species to acclimate to the projected environmental change through phenotypic plasticity. Determining the effects of higher temperatures on individual performance is made more complex by the potential for environmental conditions experienced in previous and current generations to independently affect phenotypic responses to high temperatures. We used a model coral reef fish (Acanthochromis polyacanthus) to investigate the influence of thermal...

Data from: Evidence for enemy release and increased seed production and size for two invasive Australian acacias

Marta Correia, Daniel Montesinos, Kristine French & Susana Rodríguez-Echeverría
Invasive plants are hypothesized to have higher fitness in introduced areas due to their release from pathogens and herbivores and the relocation of resources to reproduction. However, few studies have tested this hypothesis in native and introduced regions. A biogeographical approach is fundamental to understanding the mechanisms involved in plant invasions and to detect rapid evolutionary changes in the introduced area. Reproduction was assessed in native and introduced ranges of two invasive Australian woody legumes,...

Data from: Curvilinear telomere length dynamics in a squamate reptile

Beata Ujvari, Peter A. Biro, Jordan E. Charters, Gregory Brown, Kim Heasman, Christa Beckman, Thomas Madsen & Christa Beckmann
The lack of consensus concerning the impact of telomere length (TL) dynamics on survival emphasizes the need for additional studies to evaluate the effect of TL on key life-history processes. Using both cross-sectional and longitudinal data, we therefore explored age-specific TL dynamics in a squamate reptile: the frillneck lizard (Chlamydosaurus kingii). Our cross-sectional analyses revealed that young lizards had short TL, TL increased in medium-aged lizards, but TL decreased in older age cohorts, revealing a...

Data from: Shrub encroachment is linked to extirpation of an apex predator

Christopher E. Gordon, David J. Eldridge, William J. Ripple, Mathew S. Crowther, Ben D. Moore & Mike Letnic
The abundance of shrubs has increased throughout Earth's arid lands. This ‘shrub encroachment’ has been linked to livestock grazing, fire-suppression and elevated atmospheric CO2 concentrations facilitating shrub recruitment. Apex predators initiate trophic cascades which can influence the abundance of many species across multiple trophic levels within ecosystems. Extirpation of apex predators is linked inextricably to pastoralism, but has not been considered as a factor contributing to shrub encroachment. Here, we ask if trophic cascades triggered...

Data from: Enhanced decomposition and nitrogen mineralisation sustain rapid growth of Eucalyptus regnans after wildfire

Feike A. Dijkstra, Meaghan Jenkins, Vivien De Remy De Courcelles, Claudia Keitel, Margaret M. Barbour, Zachary E. Kayler & Mark A. Adams
Eucalyptus regnans grows rapidly from seed after wildfires, out-competing other species, thereby forming pure stands of mature forests that rank amongst the world's most carbon dense. By global standards, these forests grow on infertile soils. It is unclear how E. regnans is able to obtain large amounts nitrogen (N) from these infertile soils to support its rapid growth after fire. We measured carbon (C) and N stored in plant biomass and photosynthetic rates of E....

Data from: Three molecular markers show no evidence of population genetic structure in the Gouldian finch (Erythrura gouldiae)

Peri E. Bolton, Andrea J. West, Adam P. A. Cardilini, Jenna A Clark, Kimberley L. Maute, Sarah Legge, James Brazill-Boast, Simon C. Griffith, Lee A. Rollins & Jennalee A. Clark
Assessment of genetic diversity and connectivity between regions can inform conservation managers about risk of inbreeding, potential for adaptation and where population boundaries lie. The Gouldian finch (Erythrura gouldiae) is a threatened species in northern Australia, occupying the savannah woodlands of the biogeographically complex monsoon tropics. We present the most comprehensive population genetic analysis of diversity and structure the Gouldian finch using 16 microsatellite markers, mitochondrial control region and 3,389 SNPs from genotyping-by-sequencing. Mitochondrial diversity...
