Local thermal adaptation and limited gene flow constrain future climate responses of a marine ecosystem engineerAdam Miller
Rising ocean temperatures and extreme temperature events have precipitated declines and local extinctions in many marine species globally, but patterns of loss are often uneven across species ranges for reasons that are poorly understood. Knowledge of the extent of local adaptation and gene flow may explain such patterns and help predict future trajectories under scenarios of climate change. We test the extent to which local differentiation in thermal tolerance is influenced by gene flow and...
1. Patterns of animal movement associated with foraging lie at the heart of many ecological studies and often animals face decisions of staying in an environment they know, versus relocating to new sites. 2. The lack of knowledge of new foraging sites means there is risk associated with a decision to relocate (e.g. poor foraging) as well as a potential benefit (e.g. improved foraging). 3. Using a unique long-term satellite tracking dataset for several sea...

Lessios, Shang Yin Vanson Liu, William B. Ludt, Hawis Madduppa, John M. Pandolfi, Robert R. Toonen, Contributing Members Of Diversity Of The Indo-Pacific Network & Michelle R. Gaither
Aim: To test hypothesized biogeographic partitions of the tropical Indo-Pacific Ocean with phylogeographic data from 56 taxa, and to evaluate the strength and nature of barriers emerging from this test. Location: The Indo-Pacific Ocean. Time Period: Pliocene through the Holocene. Major Taxa Studied: 56 marine species. Methods: We tested eight biogeographic hypotheses for partitioning of the Indo-Pacific using a novel modification to analysis of molecular variance. Putative barriers to gene flow emerging from this analysis...
Data from: Tracing the rise of malignant cell lines: distribution, epidemiology and evolutionary interactions of two transmissible cancers in Tasmanian devilsSamantha James, Geordie Jennings, Young Mi Kwon, Maximilian Stammnitz, Alexandra Fraik, Andrew Storfer, Sebastien Comte, David Pemberton, Samantha Fox, Bill Brown, Ruth Pye, Gregory Woods, Bruce Lyons, Paul Hohenlohe, Hamish McCallum, Hannah V.

Emerging infectious diseases are rising globally and understanding host-pathogen interactions during the initial stages of disease emergence is essential for assessing potential evolutionary dynamics and designing novel management strategies. Tasmanian devils (Sarcophilus harrisii) are endangered due to a transmissible cancer – devil facial tumour disease (DFTD) – that since its emergence in the 1990’s, has affected most populations throughout Tasmania. Recent studies suggest that devils are adapting to the DFTD epidemic and that disease-induced extinction...
While extreme climactic events (ECEs) are predicted to become more frequent, reliably predicting their impacts on consumers remains challenging– particularly for large consumers in marine environments. Many studies that do evaluate ECE effects focus primarily on direct effects, though indirect effects can be equally or more important. Here, we investigate the indirect impacts of the 2011 “Ningaloo Niño” marine heatwave ECE on a diverse megafauna community in Shark Bay, Western Australia. We use an 18...
A framework for mapping the distribution of seabirds by integrating tracking, demography and phenologyAna P. B. Carneiro, Elizabeth J. Pearmain, Steffen Oppel, Thomas A. Clay, Richard A.

1. The identification of geographic areas where the densities of animals are highest across their annual cycles is a crucial step in conservation planning. In marine environments, however, it can be particularly difficult to map the distribution of species, and the methods used are usually biased towards adults, neglecting the distribution of other life-history stages even though they can represent a substantial proportion of the total population. 2. Here we develop a methodological framework for...
1. Knowledge of how disturbances such as fire shape habitat structure and composition, and affect animal interactions, is fundamental to ecology and ecosystem management. Predators also exert strong effects on ecological communities, through top-down regulation of prey and competitors, which can result in trophic cascades. Despite their ubiquity, ecological importance and potential to interact with fire, our general understanding of how predators respond to fire remains poor, hampering ecosystem management. 2. To address this important...
Data from: Behavioral, energetic, and color trait integration in guppies: testing the melanocortin hypothesisFrancesca Santostefano, Kerry Fanson, John Endler & Peter Biro
Individuals of the same population differ consistently from each other in the average expression of behavioral and physiological traits. Often, such traits are integrated and thus correlated with each other. However, the underlying proximate mechanisms generating and maintaining this among-individual covariation are still poorly understood. The melanocortin hypothesis suggests that the melanocortin pathway can have pleiotropic effects linking the expression of melanin-based coloration with physiological and behavioral traits. In the present study, we test this...
Rural Landscape Case Study from ICOMOS/IUCN Connecting Practice Project: Learning about resilience and sustainability from practical experienceKristal Buckley, Gwenaelle Bourdin & Leanna Wigboldus
This paper will contribute a case study from the ICOMOS/IUCN Connecting Practice project that aims to develop new approaches to the recognition of interconnected character of natural and cultural values in heritage designation and management frameworks. Reflections on a case study from Phase III of this project (2018-2020) will focus on the natural and cultural systems that can support the resilience of agricultural and biocultural landscapes. Conducted in cooperation with the FAO (Food and Agriculture...
Beyond the 'war on nature' and the 'attackes on culture': the CultureNature Journey through Rural LandscapesSusan McIntyre-Tamwoy, Haifaa Abdulhalim & Kristal Buckley
This session moves the discussion beyond the binary concepts of wilderness as a desired ideal state vs farmlands as tortured nature. We avoid the romanticisation of rural landscapes that permeates defensive positions around agriculture and take a critical look at rural landscapes through the lens of the CNJ. We seek robust discussion on the value of rural landscapes in nature conservation and the challenge of managing cultural values in a world increasingly embracing the mechanisation...
Data from: From cryptic to colourful: evolutionary decoupling of larval and adult colour in butterfliesIliana Medina, Regina Vega-Trejo, Thomas Wallenius, Matthew Symonds & Devi Stuart-Fox
Many animals undergo complete metamorphosis, where larval forms change abruptly in adulthood. Colour change during ontogeny is common, but there is little understanding of evolutionary patterns in these changes. Here we use data on larval and adult colour for 246 butterfly species (61% of all species in Australia) to test whether the evolution of colour is coupled between life stages. We show that adults are more variable in colour across species than caterpillars and that...
