Food Web Dynamics
Food web dynamics focuses on how energy moves through organisms in an ecosystem through primary productivity (photosynthesis) and consumers. Researchers in our Marine programs study these interactions to create a “who’s eating who” web of connections between organisms in an ecosystem.
Invasive species are any species introduced to an ecosystem in which they are not native that then go on to cause disruption or harm to the functioning of that ecosystem. Marine organisms are adept at hitching rides in ballast water of ships, through hitchhiking on marine debris, or even through deliberate introduction. Researchers at UNE study these organisms and their ecological interactions and impacts in the Gulf of Maine and beyond.
There are more than 20,000 species of marine and fresh water bony fish on the planet, while mollusks alone (snails, bivalves, etc.) comprise more than 85,000 known species. Of all the expansive biodiversity contained within our oceans, the vast majority is contained within the marine invertebrates. With so much diversity, the opportunities for research in marine invertebrates are almost inexhaustible.
Life in the sea poses challenges unique to oceanic organisms, especially the smallest of those (microorganisms). By virtue of being immersed in water, they are at the mercy of the tides, currents, chemistry, and geology of the sea. Oceanography is the study of these physical properties and processes in the ocean — physical, chemical, and geological. Oceanography researchers at UNE study how these oceanographic components interact with each other and affect life in the sea.
Plankton and Microbes
With few exceptions, marine microbes and plankton form the base of the marine food web. Small but mighty, the plankton are the fuel for life in the sea. Researchers within our Marine programs study many facets of the biology, ecology, and even chemistry of this important and diverse group of organisms.
Sharks and Marine Mammals
The largest organisms in an ecosystem are often sentinels of ecosystem health and serve key roles in the health and balance of our oceans. UNE researchers study the biology and ecology of sharks and marine mammals in the Gulf of Maine and across the globe.
