Mary Alldred

Associate Professor of Environmental Science

SUNY Plattsburgh

Mary Alldred is an associate professor of environmental science at the Center for Earth and Environmental Science at SUNY Plattsburgh. She studies the influence of organisms and ecological communities on ecosystem function. Her research focuses on predicting the influence of wetland plants on denitrification, a microbial process that provides an important ecosystem service by removing excess nitrogen. Her work has also addressed the impacts of coastal management, including invasive-plant removal and coastal marsh restorations, on nitrogen cycling and ecosystem services.

Projects

Educational Displays at the LaPierre Lane Riverway

Collaborative project with the Town of Plattsburgh to develop eduational displays for the LaPierre Lane Riverway, a spur of the Saranac River Trail

Mutualistic Species Interactions

Determining the influence of mutualistic species interactions on nitrogen cycling and marsh stability in restored urban marshes

Zoom a Microbe

Let’s face it, microbes can be hard to relate to. That’s why I created the Zoom a Microbe video series, where we dive below the surface and get to know them.

Undergraduate Research Projects

Ecosystem Dynamics of the Altona Flat Rock

Collaborative project to understand short-term and long-term dynamics in the fire-dependent ecosystems of the Altona Flat Rock sandstone pavement pine barren

Urban Marsh Restoration

Investigating development of ecosystem services following urban marsh restoration using a chronosequence of restored marshes

Using Organismal Traits to Predict Ecosystem Processes

A number of studies that use plant traits to predict the effects of plants on denitrification in wetland sediments
