In 2015, a group of undergraduates from the University of Wisconsin, Madison launched boats into Lake Mendota at the edge of campus, ready to put lessons from the classrooms to the test in hands-on field research activities. As they moved through research protocols, a student brought a metal pole from the soft bottom to the… Read more »

LTER Road Trip: Vegetation Surveys Under the Waves

Collecting and recording vegetation samples.

The North Temperate Lakes LTER vegetation survey team leapt out of their research boat, wetsuits and dive gear ready to go. The survey site bordered the opposite side of Trout Lake, a straight shot from the research facility and student dorms. Two bald eagles, native to this part of Northern Wisconsin, appeared disgruntled at our… Read more »

LTER Road Trip: Returning Fish Diversity to Crystal Lake

Got Shrubs? Woody plants are changing ecological communities around the globe

The Knights Who Say “Ni” would be delighted by a growing trend across many of the planet’s major biomes—tree and grass species are being taken over by shrubbery. Unfortunately, this phenomenon isn’t so favorable for native vegetation that struggles to compete with an invading shrub army (the term ecologists often use is ‘woody plant encroachment’)….

Integrating Human and Environmental Responses in Urban Ecology

Multidisciplinary research is a positive shift toward understanding the complexity of human-natural systems. However, combining social science and ecological science methods does not necessarily equate to integration of ideas. Drawing from their urban ecology and environmental anthropology backgrounds, a group of LTER researchers propose using conceptual frameworks that go beyond characterizing social-ecological interactions as stepwise… Read more »

Loner Lizards Stress in Shared Shade

Sceloporus jarrovi (Yarrow's spiny lizard)

Human introverts aren’t the only ones who get stressed in shared social environments. Lizards like patchy and spread out shaded spaces where they can avoid interactions with other lizards.

LTER Road Trip: How Soil Crusts Impact the Landscape

The meadow stretched as far as the eye could see, eventually meeting a dense slope of creosote shrubland, surrounded by bronze mountains in central New Mexico. The cool of early morning had already given… Read more »
