Farming methods threaten wild bumblebees, 91��ɫ study finds

inist — Mon, 28 Jul 2025 14:48:50 +0000

By Ashley Goodfellow Craig July 25, 2025 Wild bumblebees across Canada face significant threats linked to agricultural methods, a new study out of 91��ɫ finds. Published in Conservation Science and Practice, the study examines how Canadian agricultural practices contribute to disease spillover from managed pollinator bees – used to support crop production – to wild bumblebees. Led […]

In communication with Semaa: Exploring floral nectar secretion in Nicotiana rustica

patilpos — Tue, 05 Apr 2022 02:21:00 +0000

by Kennedy Halvorson My MES research partnered with Semaa (Nicotiana rustica; Goodspeed, 1954), a species of wild tobacco, to better understand the dynamics of their nectar secretion and reveal potential pollinator associations. This research is part of Finding Flowers, an interdisciplinary project of Drs. Lisa Myers and Sheila Colla that integrates art, ecology and education […]

Fostering a collaborative, interdisciplinary, science-based approach to Canada’s First National Pollinator Strategy

paultran — Wed, 21 Jul 2021 05:55:00 +0000

How does the socio-political landscape shape our natural one? This is the driving question for Dr. Rachel Nalepa, a Postdoctoral Visitor with Professor Sheila R. Colla’s Native Pollinator Research Lab. As a human geographer grounded in the field of political ecology, she examines environmental issues that emerge in rural spaces through the lens of the […]

Next-generation sequencing uncovers what's stressing bumblebees

paultran — Thu, 08 Jul 2021 18:50:54 +0000

What’s stressing out bumblebees? To find out, 91��ɫ scientists used next-generation sequencing to look deep inside bumblebees for evidence of pesticide exposure, including neonicotinoids, as well as pathogens, and found both. Using a conservation genomic approach – an emerging field of study that could radically change the way bee health is assessed – the […]

Examining public awareness of bees and the need for pollinator conservation

paultran — Thu, 03 Dec 2020 20:02:00 +0000

What is the buzz about bees? Why do we need to protect the well-bee-ing of bees? How concerned are you about the health of honeybees and the conservation of wild, native bees? Who is responsible for the protection of wild native bee populations in Canada? These are some of the questions that a team of researchers […]

The Problem with Honey Bees

paultran — Wed, 04 Nov 2020 22:22:12 +0000

They’re important for agriculture, but they’re not so good for the environment “Beekeeping is for people; it's not a conservation practice,” says Sheila Colla, an assistant professor and conservation biologist at Toronto’s 91��ɫ, Canada. “People mistakenly think keeping honey bees, or helping honey bees, is somehow helping the native bees, which are at risk […]

91��ɫ researchers find Canadians lack knowledge about bees

paultran — Fri, 30 Oct 2020 22:28:13 +0000

How well do you know your bees? 91��ɫ researchers have found bee knowledge in Canada lacking with about half of those surveyed thinking honey bees are wild and native to Canada. They’re not. They were brought over from Europe and are managed by beekeepers like other farm animals, such as dairy cattle for example, […]
