Kati Leitner, University of California, Santa Cruz '25
My name is Kati Leitner and I am a rising senior at University of California, Santa Cruz. I am studying the impacts of gulls on nesting Black Guillemots on Appledore and Smuttynose islands. For this work, I am evaluating how the proximity of guillemot nests to gull territories affects the growth of guillemot chicks, as well as the feeding strategies of the parents. To do this, I regularly survey the rocky cliffs where the guillemots nest and “grub” for chicks to measure their weight and wing length, and fit them with federally-issued bands. These data enable me to track chick growth over the season. In addition, I use a mix of in-person watches and GoPro footage to observe the guillemots as they bring food to their nests and note the frequency of kleptoparasitism (stealing food) by Herring Gulls.
Maddie Ellms, UNH Zoology '24
Hello wider SML community! I’m Maddie Ellms, a UNH zoology graduate as of this past May. My summer independent research project replicates a study done by Dr. Arthur Borror in the 1970s, during which he mapped the breeding songbird territories on Appledore in the 1970s. I am replicating that study for this summer to provide updated distribution information for our breeding birds. This summer, I’ve revisited 5 sections across the island and listened for the songs of singing territorial males. By doing this over repeated visits throughout the summer, I have mapped the locations of numerous breeding pairs representing eight songbird species across the island. In addition to my songbird surveys, I’ve been working with gull researchers on two projects. The first has involved collecting feather samples from chicks as they grow to investigate the differences in diets across siblings for Dr. Kristen Covino. Alongside this, I’ve gathered swab samples from deceased gulls for Dr. Nichola Hill’s lab monitoring the colony for signs of avian influenza.

My research aims to make the lobster fishery more sustainable by using fish processing byproducts to make an alternative lobster bait. The project is motivated by current ecologically and economically unsustainable bait sourcing practices connected with the overfishing of traditional baitfish stocks. I’ve spent the past academic year developing a formula for a bait “cake” composed predominantly of ground haddock frames (i.e., the bones, heads, and tails left over from filleting), and this summer, I’m conducting laboratory and field testing to determine the bait’s viability. So far, I’ve designed and conducted lab trials to determine and quantify lobster preference for the new bait – compared to commercially used bait – using a two-current choice flume. In the flume, a lobster can move between currents downstream of the two baits and select one bait or the other. Video data from each trial will be used to analyze each lobster’s bait choice and draw a conclusion about the comparative success of the new, more sustainable, bait.

My research is investigating what is causing the increase in shark and seal interactions on Duck Island. So far, I have collected temperature data from the three buoys nearest Duck Island, shark interaction data from previous years, and seal abundance counts. I have also found estimates of white shark abundance and distribution from papers. I am now plotting all the possible variables against each other to find any relationships.
GRACE GUO, CORNELL UNIVERSITY '25
My project focuses on understanding the potential effects of GPS transmitter attachment on the provisioning behavior and reproductive success in roseate terns, a federally endangered seabird. I’ve been working with the Shoals Marine Lab tern program to tag roseate terns in the Seavey Island breeding colony, then setting out GoPros to record footage of the nests of tagged and untagged terns. I am conducting video data analysis to compare the feeding frequency, species, and biomass of prey brought by the parents between the two groups. In order to compare reproductive success, we are also monitoring the chicks and taking field measurements of wing length and body mass for growth rate and survival data.
MARCUS STOKES-REES, QUEEN'S UNIVERSITY '27
Hi! My name is Marcus Stokes-Rees, and I am in the class of ’27 at Queen’s University in Kingston, Ontario. This Summer I am working as one of the two Seal Interns on Appledore. Besides adding to a long-term data set on the Gulf of Maine's seal population changes, I'm diving into my own project! I'm investigating how the relationship between Gray and Harbor seals has influenced their hangout spots over the past 13 years. Specifically, I'm curious if an uptick in Gray seals on a ledge prompts Harbors to find new areas to haul-out on. While I've spent a ton of time data cleaning and wrangling, I'm now onto the exciting part: crunching numbers to see if the growing Gray population is correlated with the distribution of the Harbors. Can't wait to see what secrets the seals reveal!
MAX ZELTSAR, MIDDLEBURY COLLEGE (Class of 2024.5)
Hi, my name is Max Zeltsar, and I am about to start my last semester at Middlebury College in Vermont. This summer it’s muskrat mania here at the Shoals Marine Laboratory! My research is focused on studying the unique population of muskrats here on the island. The goal is to understand their distribution, diet, and behavior and how these may (or may not) differ from typical mainland populations. Studying all these facets of the population requires many different approaches including camera trap surveys, scat transects, hair sampling, isotope analysis, and more! Data analysis will start in the next couple of weeks so I am excited to see what we can learn about these adorable furry friends that call Appledore Island home.
ROHAN MENEZES, DARTMOUTH COLLEGE '24
Hello, I am Rohan Menezes, a recent graduate of Dartmouth College. My project aims to shed light on the importance of seabird guano for supplying nutrients to rock pool ecosystems on Appledore. Recent research has shown that seabird populations are declining globally due to human encroachment, climate change, and invasive rats on the islands they inhabit. Given this trend, scientists are trying to understand the level of change that these ecosystems will experience, especially since their excrement is a major source of nutrients. To help investigate this question on one system, I am sampling organisms at different levels of the food chain in rock pools and conducting stable isotope analysis of nutrients to determine how much these organisms depend on seabird guano for nutrients.
