Nutritional developmental history and its consequences for reproductive success in Drosophila suzukii (Diptera: Drosophilidae)

Tristan Long & Yvonne Young
The characteristics of the juvenile developmental environment of an individual can have many important consequences for their adult reproductive success as it may shape the development and expression of phenotypes that are relevant to the later operation of sexual selection. Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is an economically important invasive pest species that lays its eggs in many types of soft fruits and potentially experiences large intra-population spatial and temporal variation in its nutritional developmental...

Identifying functional impacts of heat-resistant fungi on boreal forest recovery after wildfire

Nicola Day, Steve Cumming, Kari Dunfield, Jill Johnstone, Michelle Mack, Kirsten Reid, Merritt Turetsky, Xanthe Walker & Jennifer Baltzer
Fungi play key roles in carbon (C) dynamics of ecosystems: saprotrophs decompose organic material and return C in the nutrient cycle, and mycorrhizal species support plants that accumulate C through photosynthesis. The identities and functions of extremophile fungi present after fire can influence C dynamics, particularly because plant-fungal relationships are often species-specific. However, little is known about the function and distribution of fungi that survive fires. We aim to assess the distribution of heat-resistant soil...

Data from: Nutritional geometry and fitness consequences in Drosophila suzukii, the Spotted-Wing Drosophila

Yvonne Young, Natasha Buckiewicz & Tristan A. F. Long
Since its arrival to North America less than a decade ago, the invasive Spotted-Wing Drosophila (Drosophila suzukii) has inflicted substantial economic losses on soft fruit agriculture due to its ability to oviposit into ripening fruits. More effective management approaches for this species are needed, but little is known about the factors that influence behavioral choices made by D. suzukii when selecting hosts, or the consequences that their offspring experience when developing in different environments. Using...

Data from: Community-level flammability declines over 25 years of plant invasion in grasslands

Josep Padullés Cubino, Hannah L. Buckley, Nicola J. Day, Robin Pieper & Timothy J. Curran
1. Exotic plant invasions can alter fire regimes in plant communities. Invaders often possess traits that differ from native plants in the community, resulting in increases or declines in community-level flammability, changing fire regimes, and potentially causing long-term modifications to plant community composition. Although considering traits of multiple invaders and native species together is useful to better understand how invasions change community-level flammability, few studies have done this. 2 Measured morphological and flammability traits of...

On the use of private versus social information in oviposition site choice decisions by Drosophila melanogaster females

Tristan Long & Heather Malek
Individuals are faced with decisions throughout their lifetimes, and the choices they make often have important consequences towards their fitness. Being able to discern which available option is best to pursue often incurs sampling costs, which may be largely avoided by copying the behaviour and decisions of others. Although social learning and copying behaviours are widespread, much remains unknown about how effective and adaptive copying behaviour is, as well as the factors that underlie its...

Permafrost thaw in boreal peatlands is rapidly altering forest community composition

Jennifer Baltzer, Rajit Patankar, Katherine Dearborn & Cory A. Wallace
Boreal peatlands are frequently underlain by permafrost, which is thawing rapidly. A common ecological response to thaw is the conversion of raised forested plateaus to treeless wetlands, but unexplained spatial variation in responses, combined with a lack of stand-level data, make it difficult to predict future trajectories of boreal forest composition and structure. We sought to characterize patterns and identify drivers of forest structure, composition, mortality, and recruitment in a boreal peatland experiencing permafrost thaw....

Littoral macroinvertebrate and water quality data for 32 lakes across the boreal-tundra transition in the Northwest Territories

Derek Gray & Rachel Cohen
This dataset includes macroinvertebrate and water quality data from 32 lakes sampled in the Northwest Territories, Canada, from the Dempster and Inuvik-Tuktoyaktuk Highways during July and August of 2017 and 2018. It was collected as part of a project to determine how physicochemical variables affect macroinvertebrate and fish communities in small Arctic lakes.

Data from: Land-use legacies influence tree water-use efficiency and nitrogen dynamics in recently established European forests

Rossella Guerrieri, Marta Correia, Irene Martín-Forés, Raquel Alfaro-Sánchez, Joan Pino, Arndt Hampe, Fernando Valladares & Josep Espelta
1. Forest regrowth following farmland (agriculture and pasture) abandonment has been positively associated with a number of processes including the regulation of hydrological cycling, the enhancement of soil functioning, and an increase in forest productivity and carbon (C) sequestration. Although these changes in ecosystem functioning post-farmland abandonment have been observed in multiple locations and studies, the ecophysiological basis underpinning these patterns remains unclear. Here, we examine whether increased forest expansion following pastureland abandonment is associated...

Philanthropic donor perspectives about providing harm reduction services for people living with HIV/AIDS in a hospital setting

Katherine Rudzinski, Soo Chan Carusone, Andre Ceranto, Francisco Ibáñez-Carrasco, Lisa McDonald, Dean Valentine, Adrian Guta, Elaine Hyshka, William O’Leary, Andra Cardow & Carol Strike
Abstract Background Hospital-based harm reduction services are needed to reduce drug-related harms, facilitate retention in care, and increase medical treatment adherence for people who use drugs. Philanthropic donor support plays a key role in delivering such innovative services which might fall outside current funding streams. However, little is known about how the principles, implementation, and practice of harm reduction services, which are often highly stigmatized, may impact donor behaviours. We explored this issue within Casey...

Prevalence, causes, and consequences of moral distress in healthcare providers caring for people living with dementia in long-term care during a pandemic

Lynn Haslam-Larmer, Alisa Grigorovich, Hannah Quirt, Katia Engel, Steven Stewart, Kevin Rodrigues, Pia Kontos, Arlene Astell, Josephine McMurray, AnneMarie Levy, Kathleen S Bingham, Alastair J Flint, Colleen Maxwell & Andrea Iaboni
Healthcare providers caring for people living with dementia may experience moral distress when faced with ethically challenging situations, such as the inability to provide care that is consistent with their values. The COVID-19 pandemic produced conditions in long-term care homes (hereafter referred to as ‘care homes’) that could potentially contribute to moral distress. We conducted an online survey to examine changes in moral distress during the pandemic, its contributing factors and correlates, and its impact...

Data from: A first draft of the core fungal microbiome of Schedonorus arundinaceus with and without its fungal mutualist Epichloë coenophiala

Jenna Dale & Jonathan Newman
Tall fescue (Schedonorus arundinaceus) is a cool-season grass that is commonly infected with the fungal endophyte Epichloë coenophiala. Although the relationship between tall fescue and E. coenophiala is well-studied, less is known about its broader fungal communities. We used next-generation sequencing of the ITS2 region to describe the complete foliar fungal microbiomes in a set of field-grown tall fescue plants over two years, and whether these fungal communities were affected by the presence of Epichloë....

Black spruce seed availability and viability after fire, Northwest Territories, Canada

Kirsten A. Reid, Nicola J. Day, Raquel Alfaro Sánchez, Jill F. Johnstone, Steven G. Cumming, Michelle C. Mack, Merritt R. Turetsky, Xanthe J. Walker & Jennifer L. Baltzer
Context : Black spruce ( Picea mariana ) is an important conifer in boreal North American that develops a semi-serotinous, aerial seedbank and releases a pulse of seeds after fire. Variation in post-fire seed rain has important consequences for black spruce regeneration and stand composition. Aims : We explore the possible effects of changes in fire regime on the abundance and viability of black spruce seeds following a very large wildfire season in the Northwest...
