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

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

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

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

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

Interdisciplinary Conservation Science

Interdisciplinary Conservation Science

Principal Investigator: Sheila Colla Funding: York Research Chair Term: 2020-2025 The research program over the next five years continues to combine ecology, citizen science, policy and biocultural understanding to better address pollinator conservation and management challenges. The broad objectives are to: investigate differential success of native pollinators subject to multiple environmental stressors; develop new conservation

Next-generation sequencing uncovers what's stressing bumblebees

Next-generation sequencing uncovers what's stressing bumblebees

What’s stressing out bumblebees? To find out, York University 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

Examining public awareness of bees and the need for pollinator conservation

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

The Problem with Honey Bees

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 York University, Canada. “People mistakenly think keeping honey bees, or helping honey bees, is somehow helping the native bees, which are at risk

York researchers find Canadians lack knowledge about bees

York researchers find Canadians lack knowledge about bees

How well do you know your bees? York University 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,

A biocultural and interdisciplinary approach to pollinator conservation through ecology, art and pedagogy

A biocultural and interdisciplinary approach to pollinator conservation through ecology, art and pedagogy

Co-Principal Investigators: Sheila Colla and Lisa Myers. Funding: SSHRC New Frontiers in Research Fund. Term: 2019-2022. Dubbed as Finding Flowers, this interdisciplinary research project integrates art, ecology and education. Inspired by the work of the late Mi’kmaq artist Mike MacDonald, Finding Flowers grows, revitalizes and cares for native pollinator gardens as art installations, and as spaces for

An Interdisciplinary Approach to Native Pollinator Conservation in Southern Ontario: A Case Study from Norfolk County

An Interdisciplinary Approach to Native Pollinator Conservation in Southern Ontario: A Case Study from Norfolk County

Principal Investigator: Sheila Colla. Funding: W. Garfield Weston Foundation. Term: 2016-2022. Interviews and farm tours were done with conservation program Alternative Land Use Services (ALUS) participants. These interviews took place in Norfolk County, Ontario where previous work showed bee richness to be positively impacted on the land of ALUS farmers when compared to non-ALUS sites.
