Data from: Temporal population genetics of time travelling insects: a long term longitudinal study in a seed-specialized wasp

Marie Suez, Cindy Gidoin, François Lefèvre, Jean-Noël Candau, Alain Chalon & Thomas Boivin
Many animal species experiencing spatial or interannual fluctuations of their environment are capable of prolonged diapause, a kind of dormancy that extends over more than one year. Such a prolonged diapause is commonly perceived as a temporal demographic refuge in stochastic environments, but empirical evidence is still lacking of its consequences on temporal population genetic structures. In this long-term study, we investigated how a particular pattern of prolonged diapause may influence the temporal population genetics...

A deglacial hazard cascade exemplified by the landslide, tsunami and outburst flood at Elliot Creek, Southern Coast Mountains, British Columbia, Canada

Marten Geertsema, Brian Menounos, Gemma Bullard, Jonathan Carrivick, John Clague, Chunli Dai, Davide Donati, Goran Ekstrom, Jennifer Jackson, Patrick Lynett, Manuele Pichierri, Andy Pon, Dan Shugar, Doug Stead, Justin Del Bel Belluz, Pierre Friele, Ian Giesbrecht, Derek Heathfield, Tom Millard, Sasha Nasonova, Andrew Schaeffer, Brent Ward, Darren Blaney, Erik Blaney, Camille Brillon … & Meghan Sharp
We describe and model the evolution of a recent landslide and outburst flood in the southern Coast Mountains, British Columbia, Canada. About 18 Mm3 of rock descended 1000 m from a steep valley wall and traveled across the toe of a glacier before entering a 0.6 km2 glacier lake and producing a >100-m high wave. Water overtopped the lake outlet and scoured a 10-km long channel before depositing debris on a 2 km2 fan below...

Impact of intercept trap type on plume structure: a potential mechanism for differential performance of intercept trap designs for Monochamus species

Marc C. Bouwer, Chris J. K. MacQuarrie, Oniel J. Aguirre-Gil, Bernard Slippers & Jeremy D. Allison
Studies have demonstrated that semiochemical-baited intercept traps differ in their performance for sampling insects, but we have an incomplete understanding of how and why intercept trap design effects vary among insects. This can significantly delay both the development of new and optimization of existing survey and detection tools. The development of a mechanistic understanding of why trap performance varies within and among species would mitigate this delay. The primary objective of this study was to...

Range shifts in butternut, a rare, endangered tree, in response to past climate and modern conditions

Emily Schumacher, Alissa Brown, Martin Williams, Jeanne Romero-Severson, Tannis Beardmore & Sean Hoban
Aim: Range shifts are a key process that determine species distributions and genetic patterns. A previous investigation reported that Juglans cinerea (butternut) has lower genetic diversity at higher latitudes, hypothesized to be the result of range shifts following the last glacial period. However, genetic patterns can also be impacted by modern ecogeographic conditions. Therefore, we re-investigate genetic patterns of butternut with additional northern population sampling, hindcasted species distribution models, and fossil pollen records to clarify...

VCF files of loci in approximate linkage equilibrium for two common spruce budworm larval parasitoids: Apanteles fumiferanae (Hymenoptera: Braconidae) and Glypta fumiferanae (Hymenoptera: Ichneumonidae)

Simon Legault, Julian Wittische, Michel Cusson, Jacques Brodeur & Patrick M. A. James
Periodic and spatially synchronous outbreaks of insect pests have dramatic consequences for boreal and sub-boreal forests. Within these multitrophic systems, parasitoids can be stabilizing agents by dispersing toward patches containing higher host density (the so-called birdfeeder effect). However, we know little about the dispersal abilities of parasitoids in continuous forested landscapes, limiting our understanding of the spatiotemporal dynamics of host–parasitoid systems, and constraining our ability to predict forest resilience in the context of global changes....

Earlier springs enable High-Arctic wolf spiders to produce a second clutch - supplementary data

Toke T. Høye, Jean-Claude Kresse, Amanda M. Koltz & Joseph J. Bowden
Spiders at southern latitudes commonly produce multiple clutches, but this has not been observed at high latitudes where activity seasons are much shorter. Yet the timing of snowmelt is advancing in the Arctic, which may allow some species to produce an additional clutch. To determine if this is already happening, we used specimens of the wolf spider Pardosa glacialis caught by pitfall traps from the long-term (1996-2014) monitoring program at Zackenberg, Northeast Greenland. We dissected...

Data from: Development of highly reliable in silico SNP resource and genotyping assay from exome capture and sequencing: an example from black spruce (Picea mariana)

Jean Bousquet, Nathalie Pavy, France Gagnon, Astrid Deschênes, Brian Boyle & Jean Beaulieu
Picea mariana is a widely distributed boreal conifer across Canada and the subject of advanced breeding programs for which population genomics and genomic selection approaches are being developed. Targeted sequencing was achieved after capturing P. mariana exome with probes designed from the sequenced transcriptome of Picea glauca, a distant relative. A high capture efficiency of 75.9% was reached although spruce has a complex and large genome including gene sequences interspersed by some long introns. The...

Data from: Incorporating interspecific competition into species-distribution mapping by upward scaling of small-scale model projections to the landscape

Mark Baah-Acheamfour, Charles P. A. Bourque, Fan-Rui Meng, D. Edwin Swift & Charles P.-A. Bourque
There are a number of overarching questions and debate in the scientific community concerning the importance of biotic interactions in species distribution models at large spatial scales. In this paper, we present a framework for revising the potential distribution of tree species native to the Western Ecoregion of Nova Scotia, Canada, by integrating the long-term effects of interspecific competition into an existing abiotic-factor-based definition of potential species distribution (PSD). The PSD model is developed by...

Data from: Genetic and genomic evidence of niche partitioning and adaptive radiation in mountain pine beetle fungal symbionts

Dario I. Ojeda Alayon, Clement K. M. Tsui, Nicolas Feau, Arnaud Capron, Braham Dhillon, Zhang Yiyuan, Sepideh Massoumi Alamouti, Celia K. Boone, Allan L. Carroll, Janice E.K. Cooke, Amanda D. Roe, Felix A. H. Sperling, Richard C. Hamelin, Janice E. K. Cooke & Yiyuan Zhang
Bark beetles form multipartite symbiotic associations with blue stain fungi (Ophiostomatales, Ascomycota). These fungal symbionts play an important role during the beetle's life cycle by providing nutritional supplementation, overcoming tree defences and modifying host tissues to favour brood development. The maintenance of stable multipartite symbioses with seemingly less competitive symbionts in similar habitats is of fundamental interest to ecology and evolution. We tested the hypothesis that the coexistence of three fungal species associated with the...

Data from: Ecosystem memory of wildfires affects resilience of boreal mixedwood biodiversity after retention harvest

J.A. Colin Bergeron, Jaime Pinzon, Sonya Odsen, Samuel Bartels, S. Ellen Macdonald, John R. Spence & J. A. Colin Bergeron
The extent to which past states influence present and future ecosystem characteristics (ecosystem memory (EM)) is challenging to assess because signals of past ecological conditions fade with time. Using data about seven different taxa, we show that ecological gradients initiated by wildfires up to three centuries earlier affect biotic recovery after variable retention harvest in the boreal mixedwood forest. First, we show that fire history over the last 300 years is reflected in pre-harvest species-specific...

The months are chosen by statistically comparing individual monthly means with long-term monthly means for daily total global solar irradiance, mean, minimum and maximum dry bulb temperature, mean, minimum and maximum dew point temperature, and mean and maximum wind speed. These hourly datasets are used by the engineering...

Data from: A second-generation diagnostic single nucleotide polymorphism (SNP)-based assay, optimized to distinguish among eight poplar (Populus L.) species and their early hybrids

Nathalie Isabel, Manuel Lamothe & Stacey Lee Thompson
Rapid identification of Populus L. species and hybrids can be achieved with relatively little effort through the use of primer extension-based single nucleotide polymorphism (SNP) genotyping assays. We present an optimized set of 36 SNP markers from 28 gene regions that diagnose eight poplar species (Populus angustifolia James, Populus balsamifera L., Populus deltoides Bartram, Populus fremontii Watson, Populus laurifolia Ledeb., Populus maximowiczii Henry, Populus nigra L., and Populus trichocarpa Torr. & Gray). A total of...

Data from: Mechanisms underlying spruce budworm outbreak processes as elucidated by a 14-year study in New Brunswick, Canada

T. Royama, Eldon S. Eveleigh, J. R. B. Morin, S. J. Pollock, P.C. McCarthy, G. A. McDougall, C. J. Lucarotti & P. C. McCarthy
We conducted a 14-year intensive study of spruce budworm (Choristoneura fumiferana (Clem.)) survivorship at three study plots in largely balsam fir (Abies balsamea (L.) Mill.) stands in New Brunswick, Canada, to elucidate certain key mechanisms underlying spruce budworm outbreak cycles. The study covered a peak-to-declining phase (from 1981 and 1994) of the budworm outbreak cycle that had started in the early 1960s. Frequent sampling was carried out in each plot-year to construct a practically continuous...

Data from: The effect of host condition on adult emerald ash borer (Agrilus planipennis) performance

Chris J. K. MacQuarrie
For invasive species, how successful adult insects are in various life history processes influences how well invaders can colonize and reproduce. Emerald ash borer (EAB) is a significant invasive forest insect in North America that has killed millions of ash trees. While the effect of host condition on larval performance has been examined, the effect of host condition on adult performance has not. In this study, healthy trees were girdled to simulate poor host condition...

Data from: Accuracy of genomic selection models in a large population of open-pollinated families in white spruce

Jean Beaulieu, Trevor Doerksen, Sébastien Clément, John MacKay & Jean Bousquet
Genomic selection (GS) is of interest in breeding because of its potential for predicting the genetic value of individuals and increasing genetic gains per unit of time. To date, very few studies have reported empirical results of GS potential in the context of large population sizes and long breeding cycles such as for boreal trees. In this study, we assessed the effectiveness of marker-aided selection in an undomesticated white spruce (Picea glauca (Moench) Voss) population...

Data from: Above- and belowground drivers of intraspecific trait variability across subcontinental gradients for five ubiquitous forest plants in North America

Isabelle Aubin, Françoise Cardou, Alison Munson, Madhur Anand, André Arsenault, F. Wayne Bell, Yves Bergeron, Isabelle Boulangeat, Sylvain Delagrange, Nicole J. Fenton, Dominique Gravel, François Hébert, Jill Johnstone, S. Ellen Macdonald, Azim Mallik, Anne C.S. McIntosh, Jennie R. McLaren, Christian Messier, Dave Morris, Bill Shipley, Luc Sirois, Nelson Thiffault, Laura Boisvert-Marsh & Bright B. Kumordzi
Intraspecific trait variability (ITV) provides the material for species adaptation to environmental changes. To advance our understanding of how ITV can contribute to species adaptation to a wide range of environmental conditions, we studied five widespread understory forest species exposed to both continental-scale climate gradients, and local soil and disturbance gradients. We investigated the environmental drivers of between-site leaf and root trait variation, and tested whether higher between-site ITV was associated with increased trait sensitivity...

Data from: Continent-wide population genomic structure and phylogeography of North America’s most destructive conifer defoliator, the spruce budworm (Choristoneura fumiferana)

Lisa Lumley, Esther Pouliot, Jérôme Laroche, Brian Boyle, Bryan Brunet, Roger Levesque, Felix Sperling & Michel Cusson
The spruce budworm, Choristoneura fumiferana, is presumed to be panmictic across vast regions of North America. We examined the extent of panmixia by genotyping 3650 single nucleotide polymorphism (SNP) loci in 1975 individuals from 128 collections across the continent. We found three spatially structured subpopulations: Western (Alaska, Yukon), Central (southeastern Yukon to the Manitoba-Ontario border) and Eastern (Manitoba-Ontario border and Atlantic). Additionally, the most diagnostic genetic differentiation between the Central and Eastern subpopulations was chromosomally...

Dataset of habitat quality does not predict animal population abundance on frequently disturbed landscapes

Mélodie Kunegel-Lion, Eric W. Neilson, Nicolas Mansuy & Devin W. Goodsman
The data presented here are related to the research article entitled “Habitat quality does not predict animal population abundance on frequently disturbed landscapes”. Using an individual-based model, we simulated movement of theoretical individuals in a dynamically disturbed landscape and quantified the error of predicting population spatial relative abundance using an habitat model. This dataset provides the Earth Mover's Distance (EMD) as prediction error measure obtained in simulations with varying individual step length and disturbance frequency.

Files associated with: Migration-based simulations for Canadian trees show limited tracking of suitable climate under climate change

Laura Boisvert-Marsh
Aim Species distribution models typically project climatically suitable habitat for trees in eastern North America to shift hundreds of kilometers this century. We simulated potential migration considering species’ life history and traits for 10 tree species and their ability to track climatically suitable habitat. Location Eastern Canada, covering ~3.7 million km2 Methods We simulated migration-constrained range shifts through 2100 using a hybrid approach combining projections of climatically suitable habitat based on two Representative Concentration Pathways...
