Dr. Andrew Medeiros, an Associate Professor at the School for Resource and Environmental Studies (SRES) at Dalhousie University, is at the forefront of freshwater ecology research. With a career deeply rooted in both the historical and contemporary aspects of environmental science, Dr. Medeiros's work is integral to understanding and predicting the impacts of environmental stress on freshwater resources.

Dr. Medeiros's research revolves around two main avenues: the historical influence of climate change over the past 10,000 years and predicting future change. As a freshwater ecologist, he employs methodologies like limnology, paleolimnology, and bioassessment to study lakes, lake sediments, and biological indicators.

"Limnology is just the study of lakes and water quality," Dr. Medeiros explains. "Paleolimnology involves understanding the evolution of those lakes through time by studying lake sediment, while bioassessment focuses on biological indicators found in water or lake sediment."

This interdisciplinary approach allows Dr. Medeiros to bridge the gap between ecological systems and human interactions, providing insights into how environmental and anthropogenic factors affect freshwater security.

A significant portion of Dr. Medeiros's recent work focuses on municipal water supply sustainability in Arctic communities. These communities often rely on a single reservoir, making them vulnerable to climate variability. Dr. Medeiros has conducted extensive environmental impact assessments and bioindicator analyses to understand how pollution and climate change affect these water resources.

"A lot of my work in the last couple of years is focused on understanding municipal water supply in the Arctic," he says. "We assess how climate will affect the sustainability of those resources in terms of their supply and demand."

Dr. Medeiros's research has practical applications, influencing policy and governance. His work with Parks Canada on Sable Island, for example, involves assessing the impact of horse populations on water quality. This research directly informs management practices aimed at preserving the island's delicate ecosystem.

One of the defining features of Dr. Medeiros's work is its interdisciplinary nature. He emphasizes the importance of integrating social and ecological perspectives to understand the full scope of environmental issues.

"Vulnerability means different things when applied to the environment versus people," he notes. "Understanding social reactions to environmental stress is fundamental to predicting how systems will be used and perceived in the future."

Dr. Medeiros's research also provides valuable opportunities for student engagement. SRES's flexible and interdisciplinary programs attract a diverse group of students, allowing them to pursue projects that align with their interests and career goals. This student-driven approach fosters a collaborative and innovative research environment.

"The MES and MREM programs at SRES are quite good at allowing for student engagement in broad interdisciplinary projects," Dr. Medeiros states. "Our students are able to define what inspires them and build their thesis or internship around that."

Looking ahead, Dr. Medeiros envisions his research continuing to expand in scope and impact. His work on water security in Arctic communities has already led to significant policy discussions and infrastructural improvements, highlighting the critical need for proactive measures in the face of climate change.

"We've had tangible responses from multiple levels of government regarding our water security work," he says. "While not always as fast as we'd like, these responses are crucial for ensuring sustainable water resources."

Dr. Medeiros's dedication to both the scientific and practical aspects of freshwater ecology makes him a pivotal figure in the field. His research not only advances our understanding of ecological systems but also provides actionable insights for policy and governance, ensuring that future generations can benefit from sustainable and secure freshwater resources.

Dr. Andrew Medeiros's work exemplifies the power of interdisciplinary research in addressing complex environmental challenges. Through his innovative approaches and commitment to student engagement, he continues to push the boundaries of freshwater ecology, making significant contributions to both science and society.
