Parental population range expansion before secondary contact promotes heterosis

Ailene MacPherson, Silu Wang, Ryo Yamaguchi, Loren Rieseberg & Sarah Otto
Population genomic analysis of hybrid zones is instrumental to our understanding of the evolution of reproductive isolation. Many temperate hybrid zones are formed by the secondary contact between two parental populations that have undergone post-glacial range expansion. Here we show that explicitly accounting for historical parental isolation followed by range expansion prior to secondary contact is fundamental for explaining genetic and fitness patterns in these hybrid zones. Specifically, ancestral population expansion can result in allele...

Data from: The role of behavioural flexibility in primate diversification

Maria Creighton, Dan Greenberg, Simon Reader & Arne Mooers
Identifying the factors that influence species diversification is fundamental to our understanding of the evolutionary processes underlying extant biodiversity. Behavioural innovation, coupled with the social transmission of new behaviours, has been proposed to increase rates of evolutionary diversification, as novel behaviours expose populations to new selective regimes. Thus, it is believed that behavioural flexibility may be important in driving evolutionary diversification across animals. We test this hypothesis within the primates, a taxonomic group with considerable...

Data from: Does parasitoid pressure elicit defensive polyphenism in the green peach aphid?

Yonathan Uriel
Aphids are capable of adapting to parasitoid pressure in the absence of sexual reproduction using epigenetically controlled polyphenism. Asexual lineages of aphids could thus become resistant to parasitoids over time and with repeated exposure, hampering biocontrol efforts that rely on parasitoid wasps. Prior to this study, wing polyphenism and reproductive polyphenism had been reported as parasitoid-adaptive responses in asexual lineages of at least two species of aphids, but it remained unclear whether parasitoid exposure could...

Life history and environment predict variation in testosterone across vertebrates

Jerry Husak, Matthew Fuxjager, Michele A. Johnson, Maren Vitousek, Jeremy Donald, Clinton David Francis, Wolfgang Goymann, Michaela Hau, Bonnie Kircher, Rosemary Knapp, Lynn B. Martin, Eliot Miller, Laura Schoenle & Tony Williams
Endocrine systems act as key intermediaries between organisms and their environments. This interaction leads to high variability in hormone levels, but we know little about the ecological factors that influence this variation within and across major vertebrate groups. We study this topic by assessing how various social and environmental dynamics influence testosterone levels across the entire vertebrate tree of life. Our analyses show that breeding season length and mating system are the strongest predictors of...

Data from: Indigenous knowledge of key ecological processes confers resilience to a small-scale kelp fishery

Hannah Kobluk, Keith Gladstone, Mike Reid, Kelly Brown, Kira Krumhansl & Anne Salomon
1. Feedbacks between social and ecological processes can lead to sustainable stewardship practices that support ecological resilience among harvested populations. This is evident along the world’s coast lines, where Indigenous knowledge systems have facilitated millennia of human nature coexistence. However, social-ecological conditions globally are quickly shifting, posing challenges for coastal Indigenous communities where customary harvest of ocean resources, such as kelps, need to adapt to growing markets, novel climates and changing governance regimes. Consequently, a...

Data for: Nectar-dwelling microbes of common tansy are attractive to its mosquito pollinator, Culex pipiens

Daniel Peach, C. Carroll, S. Meraj, S. Gomes, E. Galloway, A. Balcita, H. Coatsworth, N. Young, Y. Uriel, R. Gries, C. Lowenberger, M. Moore & G. Gries
There is widespread interkingdom signalling between insects and microbes. For example, microbes found in floral nectar may modify its nutritional composition and produce odorants that alter the floral odor bouquet which may attract insect pollinators. Mosquitoes consume nectar and can pollinate flowers. We identified microbes isolated from nectar of common tansy, Tanacetum vulgare , identified the microbial odorants, and tested their effect on attracting the common house mosquito, Culex pipiens . Results We collected 19...

Trans-generational viral transmission and immune priming are dose-dependent

Kenneth Wilson, David Grzywacz, Jenny Cory, Philip Donkersley & Robert Graham
It is becoming increasingly apparent that trans-generational immune priming (i.e. the transfer of the parental immunological experience to its progeny resulting in offspring protection from pathogens that persist across generations) is a common phenomenon not only in vertebrates, but also invertebrates. Likewise, it is known that covert pathogenic infections may become ‘triggered’ into an overt infection by various stimuli, including exposure to heterologous infections. Yet rarely have both phenomena been explored in parallel. Using as...

Sugar preferences of Camponotus modoc and Myrmica rubra

Asim Renyard, Regine Gries, Jan Lee, Jaime Chalissery, Sebastian Damin, Robert Britton & Gerhard Gries
A stable source of carbohydrates is essential for the longevity of ant colonies. Foraging ants must select among carbohydrate resources, such as aphid honeydew, that vary based on sugar type, volume and concentration. Using Western carpenter ants, Camponotus modoc, and European fire ants, Myrmica rubra as model species, we tested the hypothesis that ant foraging on aphid honeydew is driven by aphid-specific sugars (unique sugars biosynthesized by aphids) and that ants will selectively consume particular...

Data from: Density-dependent effects on reproductive output in a capital breeding carnivore, the northern elephant seal (Mirounga angustirostris)

Daniel Costa, Rachel Holser, Daniel Crocker, Patrick Robinson, Gitte McDonald, Melinda Fowler, Jason Hassrick, Luis Hückstädt, Sarah Peterson, Samantha Simmons & Theresa Keates
All organisms face resource limitations that will ultimately restrict population growth, but the controlling mechanisms vary across ecosystems, taxa, and reproductive strategies. Using four decades of data, we examine how variation in the environment and population density affect reproductive outcomes in a capital-breeding carnivore, the northern elephant seal (Mirounga angustirostris). This species provides a unique opportunity to examine the relative importance of resource acquisition and density-dependence on breeding success. Capital breeders accrue resources over large...

Data from: Genome-wide analysis reveals demographic and life history patterns associated with habitat modification in land-locked, deep-spawning sockeye salmon (Oncorhynchus nerka)

Farida Samad-Zada, Brett Van Poorten, Shannon Harris, Lyse Godbout & Michael Russello
Human-mediated habitat fragmentation in freshwater ecosystems can negatively impact genetic diversity, demography and life history of native biota, while disrupting the behaviour of species that are dependent on spatial connectivity to complete their life cycles. In the Alouette River system (British Columbia, Canada), dam construction in 1928 impacted passage of anadromous sockeye salmon (Oncorhynchus nerka), with the last records of migrants occurring in the 1930’s. Since that time, O. nerka persisted as a resident population...

Salmonberry stomatal density

Ron Ydenberg
Triangle Island on Canada’s Pacific coast is home to a large, globally important seabird breeding colony. The shrub Salmonberry Rubus spectabilis and tussock-forming Tufted Hairgrass Deschampsia cespitosa together form ~70% of vegetation coverage, and contain the vast majority (~90%) of seabird nesting burrows. Salmonberry has in recent decades greatly expanded its coverage, while that of Tufted Hairgrass has receded. Seabirds prefer not to burrow under Salmonberry, making its ongoing expansion a potential conservation issue. We...

Predicting the effects of reservoir water level management on the reproductive output of a riparian songbird

David Green
Yellow warblers were monitored in Revelstoke, British Columbia, Canada for 12 breeding seasons spanning 2005 to 2017. Data on the breeding biology of individually marked warblers was used to construct an individual-based model describing the effects of reservoir operations on the reproductive output of yellow warblers. This model was parameterised using data on the breeding biology of approximately 30 breeding pairs per year that a provided data on nest sites (ground elevation and nest height),...

Disease-driven mass mortality event leads to widespread extirpation and variable recovery potential of a marine predator across the eastern Pacific

Sara Hamilton, Vienna Saccomanno, Walter Heady, Alyssa-Lois Gehman, Steve Lonhart, Rodrigo Beas-Luna, Fiona Francis, Lynn Lee, Laura Rogers-Bennett, Anne Salomon & Sarah Gravem
The prevalence of disease-driven mass mortality events is increasing, but our understanding of spatial variation in their magnitude, timing, and triggers are often poorly resolved. Here, we use a novel range-wide dataset comprised of 48,810 surveys to quantify how Sea Star Wasting Disease affected Pycnopodia helianthoides, the sunflower sea star, across its range from Baja California, Mexico to the Aleutian Islands, USA. We found that the outbreak occurred more rapidly, killed a greater percentage of...

Geographic homogenization but little net change in the local richness of Canadian butterflies

Jayme Lewthwaite & Arne Mooers
Aim: Recent studies have found that local-scale plots measured through time exhibit marked variation in the change in species richness. However, the overall effect often reveals no net change. Most studies thus far have been agnostic about the identities of the species lost/gained, as well as the processes that may lead to these changes. Generalist traits may be crucial in allowing species to colonize new plots or remain resilient in situ, whereas environmental filtering may...
