Exploring Phenology through Observation, Experimentation and a Common Garden

When our snowpack finally melts away, plant species will awaken to color our landscape. Some species will risk the possibility of a spring frost and race to develop leaves and flowers, absorbing the sunlight and soil nutrients before the competition increases. Other species will delay the development of leaves until the days grow longer and […]

Interview with Dr. Stephen Kress

Atlantic puffin populations on several islands in the Gulf of Maine were decimated in the mid 1800s by hunters seeking meat, eggs, and feathers. In 1973, Dr. Stephen Kress began to restore these colonies by transplanting chicks to their former breeding grounds and emboldening them to return as adults and explore the island’s breeding habitat.

Phenology Research in Maine

For generations of folks returning each summer, the varied habitats within Acadia National Park may appear stable. However, a closer look at the historical record shows changes in both species abundance and the timing of life cycle events. Researcher Caitlin McDonough is focused on the phenology at this local site. Read more.

The Future of Sugar Maples in Maine

Predictions for future climate change may be varied, but the data suggest that the maple tapping season is happening earlier each year. This, however, may be an oversimplification of the trend. UMaine graduate student Jenny Shrum is looking deeper to determine connections between weather conditions and the rate of sap flow. An understanding of these […]

The Story of Milkweed

Maine’s hearty pod-bearing milkweed is an essential part of seasonal change. The stalky perennial provides annual food and shelter to butterflies in all stages of metamorphosis. The insects depend on the safe haven provided by Maine’s three types of milkweed plants: the sun-loving butterfly and common types and the purple-flowered swamp variety. Maine gardeners also […]
