Drones in the Service of Our Forests

If you've spent any time alive on this planet, you've probably noticed that things here work in cycles – the sun passes overhead daily, we complete one revolution around the sun every year, and the slight tilt of our planet's axis subsequently yields seasonal changes in time with these astronomical movements. The lives of plants here on earth are guided

Small mammal summer

My mentor Allyson Degrassi and I use mark and recapture methods to study small mammal populations and community dynamics in relation to hemlock decline. Degrassi is an ecologist and mammalogist who is training me in a variety of techniques that I plan to apply in future veterinary medicine work. Not only does she train and advise me on my future,

Taking Time for a Look Back

Almost ten weeks in and it feels like I've only just arrived. When I first got here, I felt like I'd have all the time in the world to finish my project, and now deadlines are approaching and it's time to crunch. I based my independent project off of the project my mentor, Ahmed Hassabelkreem, has been working on. My

Clear-cuts and carbon fluxes: observing change at Harvard Forest

I came to Harvard Forest with only a vague idea as to just how expansive and diverse the forests of New England are and with the intention of studying a scene that would have been commonplace here just over a hundred years ago – regenerating forests. With both climate change and deforestation being pressing global ecological issues, my lab group

Modeling photosynthesis in the canopy

Forests play a large role in the global carbon cycle. Forests uptake atmospheric carbon through photosynthesis; and release carbon back into the atmosphere through plant and microbial respiration. Statistical models have been developed to better understand gas exchange between the atmosphere and plants. These models calculate the rate of photosynthesis in leaves given the physical conditions the leaves are experiencing.

Updating the Recipe Book

A chef can spend years finding the right ingredients and steps to create a perfect dish. We would think she was crazy if she never wrote down the recipe to repeat her masterpiece after all that work. Yet, we don't bat an eye when scientists publish their results without explaining the data and calculations they used in enough detail to

Too Hot for Salamanders and Newts to Trot?

Harvard Forest is dominated by a coniferous species called Eastern Hemlock, but due to an insect pest known as the Hemlock Woolly Adelgid, the hemlocks are dying. This, in turn, affects the habitat in which Red-backed salamanders and Red-spotted newts live. The changing climate also affects the habitat of these cute little creatures. Salamanders are smooth and slimy, which many

Up Close and Personal with Hemlock Forests

As I stood looking down at a forest of green, I started to feel a welling emotion within me. Maybe a feeling of awe. Perhaps nausea due to a fear of heights. I just couldn’t help but admire the capacity a forest has to work as a single organism, similarly to the way that hundreds of bees make up an

The soil is alive……with microorganisms

Have you ever thought about what is under your feet? What is the ground you step on composed of? Well, no matter where you are on land, you are most likely either standing on soil or on something that rests on it. Thus, all terrestrial life is supported by soil at some level, but what really lives in it? This

The Roots of the Matter

I showed up at Harvard Forest blissfully ignorant of all the possible diseases you can get from tromping around in the forest all day, not to mention with an admittedly cloudy understanding of the day to day realities of ecological research.

Top Predators: What Wolves and Wolf Spiders Have in Common

People understand ripples: you throw a stone into the middle of a pond, and the effects of that action carry on far past where the stone broke the surface of the water. For me, studying ecology has always been somewhat analogous to watching ripples on a pond: the members of an ecosystem respond to each other through their various relationships,

My First Lake Coring Trip

Since I arrived at Harvard Forest, I've heard my mentor, Wyatt Oswald, use some variation of the phrase "when you go down into the mud, you go back in time" on various occasions. This concept, officially called "the law of superposition", hinges on the simple observation that younger layers of sediment are deposited over older layers. By looking through a

Global climate change with ants and slugs

Ants with Matt Combs Melting wax, digging through sand, and orchestrating the spectacular deaths of entire colonies of ants - seems more fitting for a preschooler than an undergraduate student, working a full-time job. Yet somehow, fate has landed this college senior his dream job: spending the summer in a professional scientific setting while doing things even a little kid

Hemlock trees and their pests

We got out of the truck at one of our research sites and saw two older women painting a picture of the forested road in afternoon sunlight. It was a beautiful scene, but what the artists didn’t know was that they were surrounded by stressed, thinning, and sick hemlock trees infested with the Hemlock Woolley Adelgid (HWA), the invasive insect

Underground photography of root growth

I’m still shocked by the opportunity I have been given this summer. Being from the upper-Midwest, I was unsure what I would find when I arrived at the Harvard Forest. Much to my delight, the people of Massachusetts and Harvard Forest have been friendly and welcoming. The region is beautifully forested, and the surrounding communities live up to all the

Butterflies and bumblebees

This summer, we’re studying animal movement with Dr. Elizabeth Crone and some of her “Cronies” (lab members and affiliates): post-doctoral fellow Greg Breed , Harvard OEB graduate student James Crall, and research intern Dash Donnelly. We’re looking at how anthropogenic landscape changes and resource availability affect population dynamics in two different organisms: bumblebees and butterflies. Since we’re both especially interested

Providing safe and clean water

This summer I will work with Dr. Betsy Colburn to advance a research project I started in high school. The objective of my original project was to investigate ways in which hygienic and clean water could be provided to the people of my local community back home in Uganda. My goal this summer is to build an implementable prototype of

Fine woody debris dynamics after an ice storm

I used to walk through a forest, always looking up in wonder at the tall, sturdy trees and their vast canopies. But after this summer I have a newfound appreciation for what lies underneath these great sentries of the forest realm. Among the seasonal litterfall and the rotting remains of former protectors of peaceful succession, lay my study subjects. These

Microbes in a warmer world

A major area of research here at Harvard Forest focuses on understanding the ecological changes within the forest due to a rapidly warming climate. These climate conditions are replicated at the forest using several experimentally warmed plots that are heated by resistance cables placed beneath the soil surface. In collaboration with the Marine Biological Labs (MBL), we attempted to understand

Ragweed in a changing climate

Ambrosia artemisiifolia , better known as common ragweed, is a leading cause of hay fever allergies. It grows in disturbed areas, like roadsides and abandoned fields. Increased atmospheric CO2 has been shown to increase the pollen production and growth of ragweed. Thus, with predicted changes in land use and climate, pollen production of common ragweed is likely to increase. Our

REU skydiving!

After all the work and research is done, we definitely know how to have some fun! The last weekend of the program, three fellow REU students--Lindsay Day, Alanna Yazzie, Keke Mitchel, and I decided to do something extremely exciting and go skydiving! We've all wanted to try it, so to me it seemed like the perfect way to end the

Sampling the lyford grid

A permanent plot study provides an amazing opportunity for ecological research because it allows scientists to observe changes over ecological time. While many studies take place over a few field seasons at most because of funding or other limitations, permanent plot studies allow scientists to ask questions that only be answered over years or decades by providing a larger window

Urban ecology

Whereas most of the 2011 Harvard Forest REU group conducted research in rural forested areas, my research partner Stephan Bradley and I braved the streets of inner-city Boston to expand our understanding of how urban ecosystems function with regards to urban greening. Urban greening is the expansion and conservation of vegetated areas in cities through local stewardship practices. For this

Water transport in trees

Multitudes of tightly packed rings in an old, sturdy tree hide a secret – not only do they elucidate to a discerning viewer a historical record of how much the tree grew each year for the course of its life, but these rings also contain the remnants of its once-functional woody vascular tissue, the xylem. Xylem once threaded thin streams

Climate change impacts on phenology and ecosystem processes of northeastern forests

Phenology is the study of changes in organisms due to the seasonal cycle. Phenological shifts in forest and other ecosystems, due to climate change, could have important impacts on carbon and nutrient cycling. Therefore, it is important to find easy and accurate ways of tracking phenology in numerous ecosystems over an extended period of time. The Harvard Forest has multiple

Pitcher plant communities as model food webs

Covered in mud, and smelling similar to the stagnant swamp I found myself surrounded by, I peer deep into the small cuplike leaves of the Sarracenia purpurea (Northern Pitcher Plant), a long-lived carnivorous plant. Contained in these delicate green and red veined pitchers (which have become my life for this summer) an entire detritus-based food-web thrives. This community, consisting of

Soil carbon dynamics and its controls at Harvard Forest

Like plants and animals, soils “breathe.” That is, the microbes and roots found in dirt release carbon dioxide as they respire, and then the CO2 diffuses its way into the atmosphere. Our project focuses on the rate of this diffusion, or the CO2 flux, because we hope to better understand processes that affect the storage and release of CO2 in
