Data from: Antitropicality and convergent evolution: a case study of Permian neospiriferine brachiopods

Sangmin Lee, Guang Rong Shi, Heeju Park & Jun-Ichi Tazawa
Antitropical distribution is a biogeographical pattern characterized by natural occurrences of the same species or members of the same clade in the middle- or middle-to-high-latitudinal habitats of both hemispheres, either on land or in marine environments, without appearing in the intervening tropical environments. For most of the noted examples of Permian antitropical distribution, particularly in marine invertebrates, the causes of disjunctions have been mainly linked to either dispersal or vicariance models. Little attention has been...

Data from: Combined use of GPS and accelerometry reveals fine scale three-dimensional foraging behaviour in the short-tailed shearwater

Maud Berlincourt, Lauren P. Angel & John P. Y. Arnould
Determining the foraging behaviour of free-ranging marine animals is fundamental for assessing their habitat use and how they may respond to changes in the environment. However, despite recent advances in bio-logging technology, collecting information on both at-sea movement patterns and activity budgets still remains difficult in small pelagic seabird species due to the constraints of instrument size. The short-tailed shearwater, the most abundant seabird species in Australia (ca 23 million individuals), is a highly pelagic...

Data from: The evolutionary conservation of the A Disintegrin-like and Metalloproteinase domain with Thrombospondin-1 motif metzincins across vertebrate species and their expression in teleost zebrafish

Frédéric G. Brunet, Fiona W. Fraser, Marley J. Binder, Adam D. Smith, Christopher Kintakas, Carolyn M. Dancevic, Alister C. Ward & Daniel R. McCulloch
Background: The A Disintegrin-like and Metalloproteinase domain with Thrombospondin-1 motifs (ADAMTS) enzymes comprise 19 mammalian zinc-dependent metalloproteinases (metzincins) with homologues in a wide range of invertebrates. ADAMTS enzymes have a broad range of functions in development and diseases due to their extracellular matrix remodelling activity. Here, we report a detailed characterisation of their evolutionary conservation across vertebrates. Results: Using bioinformatics complemented with de novo sequencing, gene sequences for ADAMTS enzymes were obtained from a variety...

Data from: Incorporating anthropogenic effects into trophic ecology: predator-prey interactions in a human-dominated landscape

Ine Dorresteijn, Jannik Schultner, Dale G. Nimmo, Joern Fischer, Jan Hanspach, Tobias Kuemmerle, Laura Kehoe & Euan G. Ritchie
Apex predators perform important functions that regulate ecosystems worldwide. However, little is known about how ecosystem regulation by predators is influenced by human activities. In particular, how important are top-down effects of predators relative to direct and indirect human-mediated bottom-up and top-down processes? Combining data on species' occurrence from camera traps and hunting records, we aimed to quantify the relative effects of top-down and bottom-up processes in shaping predator and prey distributions in a human-dominated...

Data from: Cover, not caging, influences chronic physiological stress in a ground-nesting bird

Laura X. L. Tan, Katherine L. Buchanan, Grainne S. Maguire & Michael A. Weston
Predator exclosures (‘nest cages’) around nests are increasingly used to enhance hatching success of declining ground-nesting birds. However, such exclosures are contentious and have been suggested to have detrimental effects on the species which they aim to protect. This study examines whether exclosures increase physiological stress of incubating birds, a hitherto unrecognised and untested potential drawback of exclosures. Red-capped plover Charadrius ruficapillus hatching success was radically altered and significantly higher for nests with exclosures (96.2%)...

Data from: The bright incubate at night: sexual dichromatism and adaptive incubation division in an open-nesting shorebird

Kasun B. Ekanayake, Michael A. Weston, Dale G. Nimmo, Grainne S. Maguire, John A. Endler & Clemens Kupper
Ornamentation of parents poses a high risk for offspring because it reduces cryptic nest defence. Over a century ago, Wallace proposed that sexual dichromatism enhances crypsis of open-nesting females although subsequent studies found that dichromatism per se is not necessarily adaptive. We tested whether reduced female ornamentation in a sexually dichromatic species reduces the risk of clutch depredation and leads to adaptive parental roles in the red-capped plover Charadrius ruficapillus, a species with biparental incubation....

Data from: A bust but no boom: responses of floodplain bird assemblages during and after prolonged drought

Katherine E. Selwood, Rohan H. Clarke, Shaun C. Cunningham, Hania Lada, Melodie A. McGeoch & Ralph Mac Nally
1. Climate change alters the frequency and severity of extreme events, such as drought. Such events will be increasingly important in shaping communities as climate change intensifies. The ability of species to withstand extreme events (resistance) and to recover once adverse conditions abate (resilience) will determine their persistence. 2. We estimated the resistance and resilience of bird species during and after a 13-year drought (the ‘Big Dry’) in floodplain forests in south-eastern Australia. 3. We...

Data from: Citizen science program shows urban areas have lower occurrence of frog species, but not accelerated declines

Martin J. Westgate, Ben C. Scheele, Karen Ikin, Anke Maria Hoefer, R. Matthew Beaty, Murray Evans, Will Osborne, David Hunter, Laura Rayner & Don A. Driscoll
Understanding the influence of landscape change on animal populations is critical to inform biodiversity conservation efforts. A particularly important goal is to understand how urban density affects the persistence of animal populations through time, and how these impacts can be mediated by habitat provision; but data on this question are limited for some taxa. Here, we use data from a citizen science monitoring program to investigate the effect of urbanization on patterns of frog species...

Data from: A genetic perspective on rapid evolution in cane toads (Rhinella marina)

Lee Ann Rollins, Mark F. Richardson & Richard Shine
The process of biological invasion exposes a species to novel pressures, in terms of both the environments it encounters and the evolutionary consequences of range expansion. Several invaders have been shown to exhibit rapid evolutionary changes in response to those pressures, thus providing robust opportunities to clarify the processes at work during rapid phenotypic transitions. The accelerating pace of invasion of cane toads (Rhinella marina) in tropical Australia during its 80-year history has been well...

Data from: Artificial selection for food colour preferences

John A. Endler & Gemma L. Cole
Colour is an important factor in food detection and acquisition by animals using visually based foraging. Colour can be used to identify the suitability of a food source or improve the efficiency of food detection, and can even be linked to mate choice. Food colour preferences are known to exist, but whether these preferences are heritable and how these preferences evolve is unknown. Using the freshwater fish Poecilia reticulata, we artificially selected for chase behaviour...

Data from: Migration strategy and pathogen risk: non-breeding distribution drives malaria prevalence in migratory waders

Nicholas J. Clark, Sonya M. Clegg & Marcel Klaassen
Pathogen exposure has been suggested as one of the factors shaping the myriad of migration strategies observed in nature. Two hypotheses relate migration strategies to pathogen infection: the ‘avoiding the tropics hypothesis’ predicts that pathogen prevalence and transmission increase with decreasing non-breeding (wintering) latitude, while the “habitat selection hypothesis” predicts lower pathogen prevalence in marine than in freshwater habitats. We tested these scarcely investigated hypotheses by screening wintering and resident wading shorebirds (Charadriiformes) for avian...

Data from: Determinants of individual foraging specialisation in large marine vertebrates, the Antarctic and Subantarctic fur seals

Laëtitia Kernaléguen, John P. Y. Arnould, Christophe Guinet & Yves Cherel
1. The degree of individual specialization in resource use differs widely among wild populations where individuals range from fully generalized to highly specialized. This interindividual variation has profound implications in many ecological and evolutionary processes. A recent review proposed four main ecological causes of individual specialization: interspecific and intraspecific competition, ecological opportunity and predation. 2. Using the isotopic signature of subsampled whiskers, we investigated to what degree three of these factors (interspecific and intraspecific competition...

Data from: Evolution of the additive genetic variance–covariance matrix under continuous directional selection on a complex behavioural phenotype

Vincent Careau, Matthew E. Wolak, Patrick A. Carter & Theodore Garland
Given the pace at which human-induced environmental changes occur, a pressing challenge is to determine the speed with which selection can drive evolutionary change. A key determinant of adaptive response to multivariate phenotypic selection is the additive genetic variance–covariance matrix (G). Yet knowledge of G in a population experiencing new or altered selection is not sufficient to predict selection response because G itself evolves in ways that are poorly understood. We experimentally evaluated changes in...

Data from: An experimental evaluation of the effects of geolocator design and attachment method on between-year survival on whinchats Saxicola rubetra

Emma Blackburn, Malcolm Burgess, Benedictus Freeman, Alice Riseley, Arin Izang, Sam Ivande, Chris Hewson, Will Cresswell & Alice Risely
Data from location logging tags have revolutionised our understanding of migration ecology, but methods of tagging that do not compromise survival need to be identified. We compared resighting rates for 156 geolocator-tagged and 316 colour ringed-only whinchats on their African wintering grounds after migration to and from eastern Europe in two separate years. We experimentally varied both light stalk length (0, 5 and 10 mm) and harness material (elastic or non-elastic nylon braid tied on,...
