Plant traits measured for Australian alpine plants

Meena Sivagowre Sritharan
Rapid evolution is likely to be an important mechanism allowing native species to adapt to changed environmental conditions. Many northern hemisphere species have undergone substantial recent changes in phenology and morphology. However, we have little information about how native species in the southern hemisphere are responding to climate change. We used herbarium specimens from 21 native alpine plant species in Kosciuszko National Park, Australia to make over 1500 measurements of plant size, leaf thickness, leaf...

Using different body size measures can lead to different conclusions about the effects of climate change

Liam Bailey, Loeske Kruuk, Richard Allen, Mark Clayton, John Stein & Janet Gardner
Aim: Declining animal body size has been proposed as a general response to increasing global temperatures that should be observed across a broad biogeographical scale. However, published studies have shown large variation in both the magnitude and direction of body size trends. We aim to investigate how the way body size is measured (body mass, structural size, body condition) may contribute to differences in body size trends between studies. Location: Semi-arid Australia. Taxon: White-plumed honeyeater...

Data from: Inbreeding avoidance, patch isolation and matrix permeability influence dispersal and settlement choices by male agile antechinus in a fragmented landscape

Sam C. Banks & David B. Lindenmayer
1. Animal dispersal is highly non-random and has important implications for the dynamics of populations in fragmented habitat. We identified interpatch dispersal events from genetic tagging, parentage analyses and assignment tests and modelled the factors associated with apparent emigration and post-dispersal settlement choices by individual male agile antechinus (Antechinus agilis, a marsupial carnivore of south-east Australian forests). 2. Emigration decisions were best modelled with on data patch isolation and inbreeding risk. 3. The choice of...

Data from: Personal information about danger trumps social information from avian alarm calls

Jessica R. McLachlan, Chaminda P. Ratnayake & Robert D. Magrath
Information about predators can mean the difference between life and death, but prey face the challenge of integrating personal information about predators with social information from the alarm calls of others. This challenge might even affect the structure of interspecific information networks: species vary in response to alarm calls, potentially because different foraging ecologies constrain the acquisition of personal information. However, the hypothesis that constrained personal information explains a greater response to alarm calls has...

Reduced avian body condition due to global warming has little reproductive or population consequences

Nina McLean, Henk Van Der Jeugd, Chris Van Turnhout, Jonathan Lefcheck & Martijn Van De Pol
Climate change has strong effects on traits such as phenology and physiology. Studies typically assume that climate-induced trait changes will have consequences for population dynamics, but explicit tests are rare. Body condition reflects energy storage and may directly affect how much can be invested in reproduction and survival. However, the causal pathway by which decreased body condition impacts population dynamics has never been quantified across multiple populations and species. Therefore, we lack a general understanding...

Speedy revelations: how alarm calls can convey rapid, reliable information about urgent danger

Jessica McLachlan & Robert Magrath
In the perpetual struggle between high-speed predators and their prey, individuals need to react in the blink of an eye to avoid capture. Alarm calls that warn of danger therefore need to do so sufficiently rapidly that listeners can escape in time. Paradoxically, many species produce more elements in their alarm calls when signalling about more immediate danger, thereby increasing the reliability of transmission of critical information but taking longer to convey the urgent message....

Prioritising source populations for supplementing genetic diversity of reintroduced southern brown bandicoots Isoodon obesulus obesulus

Natasha M. Robinson & Sam C. Banks
Reintroduction programs can benefit from optimisation of source populations to maximise genetic diversity. Here, we report an approach to guide genetic supplementation of founder individuals to maximise genetic diversity in a reintroduction program for a nationally threatened Australian ground-dwelling marsupial, the southern brown bandicoot (eastern subspecies), Isoodon obesulus obesulus. Following local extinction ~ 100 years earlier, founding individuals were reintroduced to Booderee National Park in south-eastern Australia over three years from the nearest viable wild...

Data from: Ageing and senescence across reproductive traits and survival in superb fairy-wrens (Malurus cyaneus)

Eve Cooper
Why do senescence rates of fitness-related traits often vary dramatically? By considering the full ageing trajectories of multiple traits we can better understand how a species’ life-history shapes the evolution of senescence within a population. Here, we examined age-related changes in sex-specific survival, reproduction, and several components of reproduction using a long-term study of a cooperatively-breeding songbird, the superb fairy-wren (Malurus cyaneus). We compared ageing patterns between traits by estimating standardized rates of maturation, the...

Data from: Amelioration of ocean acidification and warming effects through physiological buffering of a macroalgae

Steve Doo, Aero Leplastrier, Alexia Graba-Landry, Januar Harianto, Ross Coleman & Maria Byrne
Concurrent anthropogenic global climate change and ocean acidification is expected to have a negative impact on calcifying marine organisms. While knowledge of biological responses of organisms to oceanic stress has emerged from single species experiments, these do not capture ecologically relevant scenarios where the potential for multi-organism physiological interactions is assessed. Marine algae provide an interesting case study, as their photosynthetic activity elevates pH in the surrounding microenvironment, potentially buffering more acidic conditions for associated...

Data from: Where do animals come from during post-fire population recovery? Implications for ecological and genetic patterns in post-fire landscapes

Sam C. Banks, Lachlan McBurney, David Blair, Ian D. Davies & David B. Lindenmayer
Identifying where animals come from during population recovery can help to understand the impacts of disturbance events and regimes on species distributions and genetic diversity. Alternative recovery processes for animal populations affected by fire include external recolonization, nucleated recovery from refuges, or in situ survival and population growth. We used simulations to develop hypotheses about ecological and genetic patterns corresponding to these alternative models. We tested these hypotheses in a study of the recovery of...

Data from: Logging and fire regimes alter plant communities

Elle J. Bowd, David B. Lindenmayer, Sam C. Banks & David P. Blair
Disturbances are key drivers of plant community composition, structure and function. Plant functional traits, including life forms and reproductive strategies are critical to the resilience and resistance of plant communities in the event of disturbance. Climate change and increasing anthropogenic disturbance are altering natural disturbance regimes, globally. When these regimes shift beyond the adaptive resilience of plant functional traits, local populations and ecosystem functions can become compromised. We tested the influence of multiple disturbances, of...

Data from: The evolution of queen pheromones in the ant genus Lasius

Luke Holman, Robert Lanfear & Patrizia D'Ettorre
Queen pheromones are among the most important chemical messages regulating insect societies yet they remain largely undiscovered, hindering research into interesting proximate and ultimate questions. Identifying queen pheromones in multiple species would give new insight into the selective pressures and evolutionary constraints acting on these ubiquitous signals. Here, we present experimental and phylogenetic evidence that 3-methylalkanes, hydrocarbons present on the queen’s cuticle, are a queen pheromone throughout the ant genus Lasius. Phylogenetic analyses of the...

Data from: Measuring CO2 and HCO3- permeabilities of isolated chloroplasts using a MIMS-18O approach

Dimitri Tolleter, Vincent Chochois, Richard Poiré, G. Dean Price & Murray R. Badger
To support photosynthetic CO2 fixation by Rubisco, the chloroplast must be fed with inorganic carbon in the form of CO2 or bicarbonate. However, the mechanisms allowing the rapid passage of this gas and this charged molecule through the bounding membranes of the chloroplast envelope are not yet completely elucidated. We describe here a method allowing us to measure the permeability of these two molecules through the chloroplast envelope using a membrane inlet mass spectrometer and...

Data from: Parental effects alter the adaptive value of an adult behavioural trait

Rebecca M. Kilner, Giuseppe Boncoraglio, Jono M. Henshaw, Benjamin J. M. Jarrett, Ornela De Gasperin, Hanna Kokko, Benjamin JM Jarrett, Alfredo Attisano & Jonathan M Henshaw
The parents' phenotype, or the environment they create for their young, can have long-lasting effects on their offspring, with profound evolutionary consequences. Yet virtually no work has considered how such parental effects might change the adaptive value of behavioural traits expressed by offspring upon reaching adulthood. To address this problem, we combined experiments on burying beetles (Nicrophorus vespilloides) with theoretical modelling, and focussed on one adult behavioural trait in particular: the supply of parental care....

Data from: Demography and growth of subadult savanna trees: interactions of life history, size, fire season, and grassy understory

Patricia A. Werner & Lynda D. Prior
Tree populations in mesic (>650 mm precipitation/yr) savannas of the world have strong demographic bottlenecks to the transition of subadult trees to the canopy layer. Although such bottlenecks are a major determinant of savanna physiognomy, the factors that allow subadults to traverse the bottleneck are little studied. In a landscape-scale field experiment in a northern Australia savanna, we determined the survival and growth of 1506 permanently marked juveniles (<150 cm tall) and saplings (150–599 cm...

Data from: Fine-scale refuges can buffer demographic and genetic processes against short-term climatic variation and disturbance: a 22 year case study of an arboreal marsupial

Sam C. Banks, Thibault Lorin, Robyn E. Shaw, Lachlan McBurney, David Blair, Michaela D. J. Blyton, Annabel L. Smith, Jennifer C. Pierson, David B. Lindenmayer & Michaela D.J. Blyton
Ecological disturbance and climate are key drivers of temporal dynamics in the demography and genetic diversity of natural populations. Microscale refuges are known to buffer species’ persistence against environmental change, but the effects of such refuges on demographic and genetic patterns in response to short-term environmental variation are poorly understood. We quantified demographic and genetic responses of mountain brushtail possums (Trichosurus cunninghami) to rainfall variability (1992–2013) and to a major wildfire. We hypothesized that there...

Data from: Relative costs of offspring sex and offspring survival in a polygynous mammal

Hannah Froy, Craig A. Walling, Josephine M. Pemberton, Tim H. Clutton-Brock, Loeske E.B. Kruuk & Loeske E. B. Kruuk
Costs of reproduction are expected to be ubiquitous in wild animal populations and understanding the drivers of variation in these costs is an important aspect of life-history evolution theory. We use a 43 year dataset from a wild population of red deer to examine the relative importance of two factors that influence the costs of reproduction to mothers, and to test whether these costs vary with changing ecological conditions. Like previous studies, our analyses indicate...

Data from: “Direct PCR” optimization yields a rapid, cost-effective, non-destructive, and efficient method for obtaining DNA barcodes without DNA extraction

Wing Hing Wong, Ywee Chieh Tay, Jayanthi Puniamoorthy, Michael Balke, Peter S. Cranston & Rudolf Meier
Macroinvertebrates that are collected in large numbers pose major problems in basic and applied biodiversity research: identification to species via morphology is often difficult, slow, and/or expensive. DNA barcodes are an attractive alternative or complementary source of information. Unfortunately obtaining DNA barcodes from specimens requires many steps and thus time and money. Here, we promote a short-cut to DNA barcoding; i.e., a non-destructive PCR method that skips DNA extraction (“direct PCR”) and that can be...

Data from: Predation can select for later and more synchronous arrival times in migrating species

Anna M. F. Harts, Nadiah P. Kristensen & Hanna Kokko
For migratory species, the timing of arrival at breeding grounds is an important determinant of fitness. Too early arrival at the breeding ground is associated with various costs, and we focus on one understudied cost: that migrants can experience a higher risk of predation if arriving earlier than the bulk of the breeding population. We show, using both a semi-analytic and simulation model, that predation can select for later arrival. This is because of safety...

Data from: Do aggressive signals evolve toward higher reliability or lower costs of assessment?

Paweł Ręk
It has been suggested that the evolution of signals must be a wasteful process for the signaller, aimed at the maximization of signal honesty. However, the reliability of communication depends not only on the costs paid by signallers but also on the costs paid by receivers during assessment, and less attention has been given to the interaction between these two types of costs during the evolution of signalling systems. A signaller and receiver may accept...

Data from: More partners, more ranges: generalist legumes spread more easily around the globe

Tia L. Harrison, Anna K. Simonsen, John R. Stinchcombe & Megan E. Frederickson
How does mutualism affect range expansion? On one hand, mutualists might thrive in new habitats thanks to the resources, stress tolerance, or defense provided by their partners. On the other, specialized mutualists might fail to find compatible partners beyond their range margins, limiting further spread. A recent global analysis of legume ranges found that non-symbiotic legumes have been successfully introduced to more ranges than legumes that form symbioses with rhizobia, but there is still abundant...

Data from: Taxon cycle predictions supported by model-based inference in Indo-Pacific trap-jaw ants (Hymenoptera: Formicidae: Odontomachus)

Pável Matos-Maraví, Nicholas J. Matzke, Fredrick J. Larabee, Ronald M. Clouse, Ward C. Wheeler, Daniela Magdalena Sorger, Andrew V. Suarez & Milan Janda
Non-equilibrium dynamics and non-neutral processes, such as trait-dependent dispersal, are often missing from quantitative island biogeography models despite their potential explanatory value. One of the most influential non-equilibrium models is the taxon cycle, but it has been difficult to test its validity as a general biogeographical framework. Here, we test predictions of the taxon-cycle model using six expected phylogenetic patterns and a time-calibrated phylogeny of Indo-Pacific Odontomachus (Hymenoptera: Formicidae: Ponerinae), one of the ant genera...
