How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I am currently a PhD student with Prof. Easton White working on marine organism response to extreme events and gradual warming. I was a 2022 Knauss Marine Policy Fellow working within NOAA Fisheries on Arctic policy and communicating NMFS' science enterprise. In 2020, I graduated with MS from UMass Amherst in Marine Ecology, working on intraspecific variation in trait performance in a species of marine snail along latitudinal gradients. https://github.com/villesci/
February 2021 - January 2022
- I am a 2021 Knauss Marine Policy Fellow with NOAA Fisheries. For the science side of my portfolio, I create one-pagers about Fisheries surveys, analyze NMFS bibliometrics, and respond to taskers. I support NOAA Arctic policy by assisting the co-chair of the Arctic Action Team, serve as rapporteur for Central Arctic Ocean Fisheries Agreement meetings, and serve as a secretariat member of the Interagency Arctic Research Policy Committee (IARPC).

- Graduate Teaching Assistant
- I was a TA for several undergraduate courses, including lab section prep and guest lecturing. Fall 2018 - Marine Ecology Spring 2019 - Ecology
The recently described species Brookesia micra is endemic to the islet of Nosy Hara in northern Madagascar, and is the smallest chameleon species that has been described. Here, I present the first quantitative data on density, behavioral, habitat selection, and natural history on B. micra. I observed 117 B. micra from10–23 April 2015. Estimated den...
Models of species response to climate change often assume that physiological traits are invariant across populations. Neglecting potential intraspecific variation may overlook the possibility that some populations are more resilient or susceptible than others, creating inaccurate predictions of climate impacts. In addition, phenotypic plasticity ca...
Populations within species often exhibit variation in traits that reflect local adaptation and further shape existing adaptive potential for species to respond to climate change. However, our mechanistic understanding of how the environment shapes trait variation remains poor. Here, we used common garden experiments to quantify thermal performance...
Many species face extinction risks owing to climate change, and there is an urgent need to identify which species' populations will be most vulnerable. Plasticity in heat tolerance, which includes acclimation or hardening, occurs when prior exposure to a warmer temperature changes an organism's upper thermal limit. The capacity for thermal acclimat...
Warming threatens biodiversity but there is considerable uncertainty in which species and ecosystems are most vulnerable. Moreover, our understanding of organismal sensitivity is largely centered on species level assessments, which do not consider variation across populations. Here, we used meta-analysis to quantify differentiation in thermal toler...
As the earth’s climate changes due to anthropogenic emissions, it has increasingly become an imperative within the ecological community to understand existing species adaptations to climate change. Much focus has been paid to how a species might react to climate change, but the role of locally adapted traits and responsible environmental mechanisms...
The snail Nereina punctulata has been observed performing amphidromous migrations (salt to freshwater migration, post-larval settlement) in the Caribbean, with small-and medium-sized snails achieving maximum fitness at the mid-and high altitudes, but they may be restricted by energy stores. Large snails show no difference in fitness across altitude...
Insects that pupate on the branches of trees and shrubs suffer mortality from both predators and parasitic wasps. Which natural enemy represents the greater threat and therefore the stronger selection force on pupation site selection depends upon the time of year, the relative abundance of predators versus parasitoids, and the availability of alter...
The colonial tunicate Didemnum vexillum is a circumglobal, cryptogenic invasive species originating from the Sea of Japan and is currently found in New Zealand, British Columbia, Northwest Atlantic, and the Northeast Atlantic. It was first introduced to the Gulf of Maine in the 1970s on materials linked to shellfish aquaculture, most likely in the...
The micro leaf chameleon genus Brookesia is exclusively endemic to Madagascar and represents some of the smallest reptiles in the world. The newly-described species Brookesia micra is exclusively endemic to the islet Nosy Hara in the north of Madagascar, and is the smallest described Brookesia species member. There exists no density, behavioral, or...
Abstract Marine settlement communities, composed of organisms having a planktonic juvenile state and a sessile adult state, are some of the first organisms to colonize virgin surfaces introduced into seawater. This project attempted to quantify settlement community diversity differences between low and high current treatments on Kent Island, Bay of...
Hurricane Maria devastated Dominica, West Indies, in November 2017 causing significant social and ecological impacts. This project, a part of Operation Wallacea's ongoing work on the island, will engage students with the concept ecosystem resilience, and form the basis of a longitudinal study that will explore how the ecology of the streams across the island has been impacted. We will do this by studying the invertebrate community and it's functional diversity, and changes in the riparian input (a key basal resource) from source to river.
