Design: Systematic scoping review. Primary and secondary outcome measures: Extracted data included location, study characteristics and whether trials corresponded to causes of mortality and identified research priority topics. Results: Our search identified 7,269...

Data from: Iridescence untwined - Honey bees can separate hue variations in space and time

Leslie Ng, Laura Ospina-Rozo, Jair Garcia, Adrian Dyer & Devi Stuart-Fox
Iridescence is a phenomenon whereby the hue of a surface changes with viewing or illumination angle. Many animals display iridescence but it currently remains unclear whether relevant observers process iridescent color signals as a complex collection of colors (spatial variation), or as moving patterns of colors and shapes (temporal variation). This is important as animals may use only the spatial or temporal component of the signal, although this possibility has rarely been considered or tested....

The evolution of conspicuousness in frogs: when to signal toxicity?

Iliana Medina
Many organisms use conspicuous color patterns to advertise their toxicity or unpalatability, a strategy known as aposematism. Despite the recognized benefits of this antipredator tactic, not all chemically defended species exhibit warning coloration. Here, we use a comparative approach to investigate which factors predict the evolution of conspicuousness in frogs, a group in which conspicuous coloration and toxicity have evolved multiple times. We extracted color information from dorsal and ventral photos of 594 frog species...

Dataset for: Guidelines for standardising the application of discriminant analysis of principal components to genotype data

Joshua Thia
Data and scripts required to replicate the analyses in Thia (2022) "Guidelines for standardising the application of discriminant analysis of principal components to genotype data" in Molecular Ecology. This study aimed to address methodological misunderstandings and misuse of the DAPC method in population genetics. The analyses are used to illustrate that for genotype data comprising k effective populations, there are only k−1 PC axes that describe populations structure, and that are biologically informative. These PC...

Pretty cool beetles: Can manipulation of visible and near-infrared sunlight prevent overheating?

Laura Ospina Rozo, Jegadesan Subbiah, Ainsley Seago & Devi Stuart-Fox
Passive thermoregulation is an important strategy to prevent overheating in thermally challenging environments. Can the diversity of optical properties found in Christmas beetles (Rutelinae) be an advantage to keep cool? We measured changes in temperature of the elytra of 26 species of Christmas beetles, exclusively due to direct radiation from a solar simulator in visible (VIS: 400–700 nm) and near-infrared (NIR: 700–1700 nm) wavebands. Then, we evaluated if the optical properties of elytra could predict...

Whole genome resequencing reveals signatures of rapid selection in a virus affected commercial fishery

Owen Holland, Madeline Toomey, Collin Ahrens, Ary Hoffman, Larry Croft, Craig Sherman & Adam Miller
Infectious diseases are recognised as one of the greatest global threats to biodiversity and ecosystem functioning. Consequently, there is a growing urgency to understand the speed at which adaptive phenotypes can evolve and spread in natural populations to inform future management. Here we provide evidence of rapid genomic changes in wild Australian blacklip abalone (Haliotis rubra) following a major population crash associated with an infectious disease. Genome scans on H. rubra were performed using pooled...

Rates of dispersal of cane toads during their global invasion

Richard Shine, Ross Alford, Ryan Blennerhasset, Gregory Brown, Jayna DeVore, Simon Ducatez, Patrick Finnerty, Matthew Greenlees, Shannon Kaiser, Samantha McCann, Lachlan Pettit, Ligia Pizzatto, Lin Schwarzkopf, Georgia Ward-Fear & Benjamin Phillips
Invasions often accelerate through time, as dispersal-enhancing traits accumulate at the expanding range edge. How does the dispersal behaviour of individual organisms shift to increase rates of population spread? We collate data from 44 radio-tracking studies (in total, of 650 animals) of cane toads (Rhinella marina) to quantify distances moved per day, and the frequency of displacement in their native range (French Guiana) and two invaded areas (Hawai’i and Australia). Here we show that toads...

Amphibian resistance to chytridiomycosis increases following low virulence chytrid fungal infection or drug-mediated clearance

Anthony Waddle
Amphibian biodiversity is experiencing ongoing declines due in part to the infectious disease, chytridiomycosis. Efforts to mitigate the effects of the causal agent of chytridiomycosis, Batrachochytrium dendrobatidis (Bd), in the wild have not been wholly effective. Translocations are an important management tool for amphibians, and immunizations represent a possible strategy for preparing amphibians for release across a landscape where Bd exists. We evaluated the utility of using an isolate of Bd that was shown to...

Nest architecture is linked with ecological success in songbirds

Iliana Medina, Daniela Perez, Ana C Afonso Silva, Justin Cally, Constanza Leon, Odile Maliet & Ignacio Quintero
Nests are essential constructions that directly determine fitness, yet their structure can vary substantially across bird species. While there is evidence supporting a link between nest architecture and the habitat a species occupies, we still ignore what ecological and evolutionary processes are linked to different nest types. Using information on 3175 species of songbirds, we show that – after controlling for latitude and body size – species that build domed nests (i.e., nests with a...

Richness and abundance of both butterflies and floral resources in residential gardens across southwestern Melbourne, Australia’s greater metropolitan area

Jessica Kurylo, Karl Evans, Kirsten Parris, Nicholas Williams & Caragh Threlfall
Wildlife gardening is a popular activity undertaken within residential areas. It is broadly promoted as a means of encouraging residents to make their gardens more ‘wildlife friendly’. While theory and anecdotal evidence suggest these schemes should be effective, quantitative evaluation of wildlife gardening practices and programs is lacking across most taxa they target. Our overall objective in collecting this data was to determine if there was a difference in butterfly richness or abundance between gardens...

Population genomics and sexual signals identify reproductive interference in Uperoleia

Renee Catullo, Frederick Jaya, Jessie Tanner, Michael Whitehead, Paul Doughty, Scott Keogh & Craig Moritz
When closely related species come into contact via range expansion, both may experience reduced fitness as a result of the interaction. Selection is expected to favor traits that minimize costly interspecies reproductive interactions (such as mismating) via a phenomenon called reproductive character displacement (RCD). Research on RCD frequently assumes secondary contact between species, but the geographic history of species interactions is often unknown. Landscape genomic data allows tests of geographic hypotheses about species origins and...

Close kin dyads indicate intergenerational dispersal and barriers

Thomas Schmidt
The movement of individuals through continuous space is typically constrained by dispersal ability and dispersal barriers. A range of approaches have been developed to investigate these. Kindisperse is a new approach that infers intergenerational dispersal (σ) from close kin dyads, and appears particularly useful for investigating taxa that are difficult to observe individually. This study, focusing on the mosquito Aedes aegypti, shows how the same close kin data can also be used for barrier detection....

Counting the bodies: estimating the numbers and spatial variation of Australian reptiles, birds and mammals killed by two invasive mesopredators

Alyson Stobo-Wilson, Brett Murphy, Sarah Legge, Hernan Caceres-Escobar, David Chapple, Heather Crawford, Stuart Dawson, Chris Dickman, Tim Doherty, Patricia Fleming, Stephen Garnett, Matthew Gentle, Thomas Newsome, Russell Palmer, Matthew Rees, Euan Ritchie, James Speed, John-Michael Stuart, Andres Suarez-Castro, Eilysh Thompson, Ayesha Tulloch, Jeff Turpin & John Woinarski
Aim: Introduced predators negatively impact biodiversity globally, with insular fauna often most severely affected. Here, we assess spatial variation in the number of terrestrial vertebrates (excluding amphibians) killed by two mammalian mesopredators introduced to Australia, the red fox (Vulpes vulpes) and feral cat (Felis catus). We aim to identify prey groups that suffer especially high rates of predation, and regions where losses to foxes and/or cats are most substantial. Location: Australia Methods: We draw information...

The minimum land area requiring conservation attention to safeguard biodiversity

James Allan, Hugh Possingham, Scott Atkinson, Anthony Waldron, Moreno Di Marco, Stuart Butchart, Vanessa Adams, Daniel Kissling, Thomas Worsdell, Chris Sandbrook, Gwili Gibbon, Kundan Kumar, Piyush Mehta, Martine Maron, Brooke Williams, Kendall Jones, Brendan Wintle, April Reside & James Watson
Ambitious conservation efforts are needed to stop the global biodiversity crisis. Here, we estimate the minimum land area to secure important biodiversity areas, ecologically intact areas, and optimal locations for representation of species ranges and ecoregions. We discover that at least 64 million km2 (44% of terrestrial area) would require conservation attention (ranging from protected areas to land-use policies) to meet this goal. Over 1.8 billion people live on these lands, so responses that promote...

Environmental gradients predict the ratio of environmentally acquired carotenoids to self-synthesised pteridine pigments

Devi Stuart-Fox, Katrina Rankin, Adrian Lutz, Adam Elliot, Andrew Hugall, Claire McLean & Iliana Medina
Carotenoids are important pigments producing integument coloration; however, their dietary availability may be limited in some environments. Many species produce red to yellow hues using a combination of carotenoids and self-synthesised pteridine pigments. A compelling but untested hypothesis is that pteridines replace carotenoids in environments where carotenoid availability is limited. Based on a phylogenetic comparative analysis of pigment concentrations in agamid lizards, we show that environmental gradients predict the ratio of carotenoids to pteridines; carotenoid...

Data and original code for: A generalized approach to characterise optical properties of natural objects

Laura Ospina-Rozo, Ann Roberts & Devi Stuart-Fox
To understand the diversity of ways in which natural materials interact with light, it is important to consider how their reflectance changes with the angle of illumination or viewing and to consider wavelengths beyond the visible. We chose a set of existing measurements and parameters that are generalisable to any wavelength range and spectral shape and we highlight which subsets of measures are relevant to different biological questions. As a case study, we applied these...

Automatic analysis of cochlear response using electrocochleography signals during cochlear implant surgery

Sudanthi Wijewickrema, Christopher Bester, Jean-Marc Gerard, Aaron Collins & Stephen O'Leary
Cochlear implants (CIs) provide an opportunity for the hearing impaired to perceive sound through electrical stimulation of the hearing (cochlear) nerve. However, there is a high risk of losing a patient's natural hearing during CI surgery, which has been shown to reduce speech perception in noisy environments as well as music appreciation. This is a major barrier to the adoption of CIs by the hearing impaired. Electrocochleography (ECochG) has been used to detect intra-operative trauma...

A field test of mechanisms underpinning animal diversity in recently burned landscapes

Katharine Senior, Katherine Giljohann, Michael McCarthy & Luke Kelly
1. Planned burning generates different types of pyrodiversity, however, experimental tests of how alternative spatial patterns of burning influence animal communities remain rare. Field tests are needed to understand the mechanisms through which spatial variation in planned fire affects fauna, and how fire can be applied to benefit biodiversity. 2. We tested five hypotheses of how fire-driven variation in habitat composition and configuration affects fauna at fine scales. Small mammal, reptile and invasive predator activity...

Data from: The effect of copy number hemiplasy on gene family evolution

Qiuyi Li, Yao-Ban Chan, Nicolas Galtier & Celine Scornavacca
The evolution of gene families is complex, involving gene-level evolutionary events such as gene duplication, horizontal gene transfer, and gene loss (DTL), and other processes such as incomplete lineage sorting (ILS). Because of this, topological differences often exist between gene trees and species trees. A number of models have been recently developed to explain these discrepancies, the most realistic of which attempt to consider both gene-level events and ILS. When unified in a single model,...
