Data for "Gut yeasts accelerate chill coma recovery in Drosophila melanogaster"

Yanira Jiménez-Padilla, Brent J. Sinclair

Metadata are provided in each data sheet.AbstractThe role of microbial symbionts in host stress tolerance remains underexplored. Gut microbiome studies in Drosophila melanogaster have largely focused on bacteria, whereas yeasts have been assumed to provide nutrition rather than engage in true symbiosis. …

Oxygen availability and oxygen delivery but not oxidative stress shape heat tolerance in diploid and triploid zebrafish larvae

Stefane Saruhashi, Jeroen G. J. Boerrigter, Maartje H. L. Hooymans, Brent J. Sinclair et autres

The oxygen- and capacity-limited thermal tolerance (OCLTT) hypothesis predicts that limits to oxygen availability or delivery set upper thermal boundaries. We tested this by manipulating oxygen concentration and delivery capacity (comparing diploid and triploid zebrafish larvae, which differ in cell size and …

Gut yeasts accelerate chill coma recovery in Drosophila melanogaster

Yanira Jiménez-Padilla, Brent J. Sinclair

The role of microbial symbionts in host stress tolerance remains underexplored. Gut microbiome studies in Drosophila melanogaster have largely focused on bacteria, whereas yeasts have been assumed to provide nutrition rather than engage in true symbiosis. We explored the effect of gut …

Why do Canadian winters limit the success of Hypena opulenta (Lepidoptera: Erebidae), a biological control agent for invasive swallow-worts (Apocynaceae)?

Ian M. Jones, Brent J. Sinclair, Carla Timm, Sandy M. Smith et autres

Abstract Hypena opulenta (Lepidoptera: Erebidae) has been introduced to control invasive swallow-worts (Apocynaceae) in North America. However, population densities remain too low to suppress weed populations. We examined winter cold and soil moisture as potential factors limiting H. opulenta population growth in …

Can we predict ectotherm responses to climate change using thermal performance curves and body temperatures?

Brent J. Sinclair, Stine Slotsbo, Yun‐Wei Dong, Raymond B. Huey et autres

Thermal performance curves (TPCs), which quantify how an ectotherm's body temperature (Tb ) affects its performance or fitness, are often used in an attempt to predict organismal responses to climate change. Here, we examine the key - but often biologically unreasonable - …

Cold tolerance strategy and lower temperature thresholds of Lycorma delicatula (Hemiptera: Fulgoridae) egg masses

Anna J. Turbelin, Brent J. Sinclair, John Rost, Amanda Diane Roe

The spotted lanternfly (Lycorma delicatula, Hemiptera: Fulgoridae) is a planthopper native to China and southeastern Asia invasive in North America. To inform the risk assessment of northward spread, we determined the cold tolerance strategy and lower lethal limits of overwintering eggs. We …

Effects of acclimation on the cold tolerance of the pepper weevil

D. Catalina Fernández, Sherah L. VanLaerhoven, Brent J. Sinclair, Roselyne M. Labbe

Abstract The pepper weevil, Anthonomus eugenii , is a subtropical pest of pepper plants that appears to be expanding its geographic range as evidenced by its increasing occurrence and persistence in field and greenhouse pepper crops in temperate areas. Here, we investigated …

Stimulating a Canadian narrative for climate

Catherine Potvin, Divya Sharma, Irena F. Creed, Sally N. Aitken et autres

This perspective documents current thinking around climate actions in Canada by synthesizing scholarly proposals made by Sustainable Canada Dialogues (SCD), an informal network of scholars from all 10 provinces, and by reviewing responses from civil society representatives to the scholars’ proposals. Motivated …
