Current Research in the Melcher Lab

Cold and Freezing Tolerance

I’m examining how East Coast plants tolerate freezing stress and the factors that influence their resistance to freezing injury. Working across species ranging from mosses to trees, I investigate how these mechanisms vary among plants and respond to different environmental conditions.

Marine Seagrasses and their environment

This is a new project in the lab. I am looking at how the tropical seagrasses compare to temperate seagrass species in response to temperature, salinity, light and nutrients and investigating questions on why these different species can tolerate different ocean conditions.

Coastal Ecophysiology and Introduced Species

I have been investigating how introduced species affect endemic plants on island systems. My current research explores the interactions between introduced and native plants, the factors that shape their responses, in coastal dune sites in Puerto Rico.

Aashika Shah measuring cold toleranace of plants

We are investigating factors that alter freezing resistance mechanism in different species. In this experiment Aashika is studying red pine and how its ability to tolerate freezing alters during warm and cold spells over winter.
