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...

SNP analyses reveal a diverse pool of potential colonists to earthquake‐uplifted coastlines

Johnette Peters, Jonathan Waters, Ludovic Dutoit & Ceridwen Fraser
In species that form dense populations, major disturbance events are expected to increase the chance of establishment for immigrant lineages. Real-time tests of the impact of disturbance on patterns of genetic structure are, however, scarce. Central to testing these concepts is determining the pool of potential immigrants dispersing into a disturbed area. In 2016, a 7.8 magnitude earthquake occurred on the South Island of New Zealand. Affecting approximately 100 km of coastline, this quake caused...

Data from: Social foraging extends associative odor-food memory expression in an automated learning assay for Drosophila melanogaster

Aarti Sehdev, Yunusa Mohammed, Cansu Tafrali & Paul Szyszka
Animals socially interact during foraging and share information about the quality and location of food sources. The mechanisms of social information transfer during foraging have been mostly studied at the behavioral level, and its underlying neural mechanisms are largely unknown. Fruit flies have become a model for studying the neural bases of social information transfer, because they provide a large genetic toolbox to monitor and manipulate neuronal activity, and they show a rich repertoire of...

Data from: DNA methylation predicts immune gene expression in introduced house sparrows (Passer domesticus)

Holly J. Kilvitis, Aaron W. Schrey, Alexandria K. Ragsdale, Alejandro Berrio, Steve M. Phelps & Lynn B. Martin
Populations undergoing range expansions are often faced with novel selective pressures, and to cope with such challenges, populations must either adapt quickly or exhibit phenotypic plasticity. This latter option allows for rapid phenotypic adjustments and persistence in novel environments, and thus could be advantageous at range‐edges. Our previous research on house sparrows in Kenya—a site of ongoing range expansion— and a growing literature suggests that invasion success is facilitated by epigenetic regulation of gene expression....

Vertical transmission of a nematode from female lizards to the brains of their offspring

Nathalie Feiner, Sueli De Souza-Lima, Fátima Jorge, Soraya Naem, Fabien Aubret, Tobias Uller & Steven Nadler
Parasites have evolved a diversity of life styles that exploit the biology of their hosts. Some nematodes that parasitize mammals pass via the placenta or milk from one host to another. Similar cases of vertical transmission have never been reported in avian and non-avian reptiles, suggesting that egg laying may constrain themeans of parasite transmission. However, here we report the first incidence of transovarial transmission of a previously undescribed nematode in an egg-laying amniote, the...

Data from: A high-density exome capture genotype-by-sequencing panel for forestry breeding in Pinus radiata

Emily J Telfer, Natalie J Graham, Yongjun Li, Jaroslav Klapste, , Leandro G Neves, Heidi Dungey & Phillip Wilcox
Development of genome-wide resources for application in genomic selection or genome-wide association studies, in the absences of full reference genomes, present a challenge to the forestry industry, where longer breeding cycles could benefit from the accelerated selection possible through marker-based breeding value predictions. In particular, large conifer megagenomes require a strategy to reduce complexity, whilst ensuring genome-wide coverage is achieved. Using a transcriptome-based reference template, we have successfully developed a high density exome capture genotype-by-sequencing...

Data from: Multiple micronutrient status and predictors of anemia in young children aged 12-23 months living in New Delhi, India

Deborah McIntosh, Geeta Trilok-Kumar, Jillian J. Haszard, Michelle J. Harper, Malcolm Reid, Jeurgen Erhardt, Karl Bailey, Rosalind S. Gibson & Lisa A. Houghton
Anemia has been identified as a severe public health concern among young children in India, however, information on the prevalence of anemia attributed to micronutrient deficiencies is lacking. We aimed to assess multiple micronutrient status (iron, zinc, selenium, vitamin A, vitamin D, folate and vitamin B12) in young Indian children and to investigate the role of these seven micronutrients and other non-nutritional factors on hemoglobin concentrations and anemia. One-hundred and twenty children aged 12 to...

Data from: Genomics detects population structure within and between ocean basins in a circumpolar seabird: the white-chinned petrel

Kalinka Rexer-Huber, Andrew J. Veale, Paulo Catry, Yves Cherel, Ludovic Dutoit, Yasmin Foster, John C. McEwan, Graham C. Parker, Richard A. Phillips, Peter G. Ryan, Andrew J. Stanworth, Tracey Van Stijn, David R. Thompson, Jonathan Waters & Bruce C. Robertson
The Southern Ocean represents a continuous stretch of circumpolar marine habitat, but the potential physical and ecological drivers of evolutionary genetic differentiation across this vast ecosystem remain unclear. We tested for genetic structure across the full circumpolar range of the white-chinned petrel (Procellaria aequinoctialis) to unravel the potential drivers of population differentiation and test alternative population differentiation hypotheses. Following range-wide comprehensive sampling, we applied genomic (genotyping-by-sequencing or GBS; 60,709 loci) and standard mitochondrial-marker approaches (cytochrome...

Data from: Ecological gradients drive insect wing loss and speciation: the role of the alpine treeline

Graham A. McCulloch, Brodie J. Foster, Ludovic Dutoit, Travis Ingram, Eleanor Hay, Andrew J. Veale, Peter K. Dearden & Jonathan M. Waters
Alpine ecosystems are frequently characterised by an abundance of wing-reduced insect species, but the drivers of this biodiversity remain poorly understood. Insect wing reduction in these environments has variously been attributed to altitude, temperature, isolation, habitat stability, or decreased habitat size. We used fine-scale ecotypic and genomic analyses, along with broad-scale distributional analyses of ecotypes, to unravel the ecological drivers of wing reduction in the wing-dimorphic stonefly Zelandoperla fenestrata complex. Altitudinal transects within populations revealed...

Data from: Does evolutionary history correlate with contemporary extinction risk by influencing range size dynamics?

Andrew J. Tanentzap, Javier Igea, Matthew G. Johnston & Matthew J. Larcombe
Extinction threatens many species, yet is predicted by few factors across the plant Tree of Life (ToL). Taxon age is one factor that may associate with extinction if occupancy of geographic and adaptive zones varies with time, but evidence for such an association has been equivocal. Age-dependent occupancy can also influence diversification rates and thus extinction risk where new taxa have small range and population sizes. To test how age, diversification, and range size were...

Data from: Facultative oviparity in a viviparous skink (Saiphos equalis)

Melanie K. Laird, Michael B. Thompson & Camilla M. Whittington
Facultative changes in parity mode (oviparity to viviparity, and vice versa) are rare in vertebrates, yet offer fascinating opportunities to investigate the role of reproductive lability in parity mode evolution. Here we report apparent facultative oviparity by a viviparous female of the bimodally reproductive skink Saiphos equalis- the first report of different parity modes within a vertebrate clutch. Eggs oviposited facultatively possess shell characteristics of both viviparous and oviparous S. equalis, demonstrating that egg coverings...

Data from: Competition and resource breadth shape niche variation and overlap in multiple trophic dimensions

Raul Costa-Pereira, Marcio S. Araújo, Franco L. Souza & Travis Ingram
Competition plays a central role in the maintenance of biodiversity. A backbone of classic niche theory is that local coexistence of competitors is favoured by the contraction or divergence of species’ niches. However, this effect should depend on the diversity of resources available in the local environment, particularly when resources vary in multiple ecological dimensions. Here, we investigated how available resource breadth (i.e., prey diversity) and competition together shape multidimensional niche variation (between and within...

Data from: Temporal variation in the vocal behaviour of southern right whales in the Auckland Islands, New Zealand

Trudi Webster, Sofie Van Parijs, Will Rayment & Steve Dawson
Autonomous recorders are frequently utilised for examining vocal behaviour of animals, and are particularly effective in remote habitats. Southern right whales are known to have an extensive acoustic repertoire. A recorder was moored at the isolated sub-Antarctic Auckland Islands for a year to examine whether the acoustic behaviour of southern right whales differed seasonally and throughout the day at their main calving ground in New Zealand. Recordings were made in each month except June, and...
