The Marine Flora of Bermuda

My present area of study is the red, green and brown algal flora of the islands that make up Bermuda. We have been barcoding the species there since 2010 in conjunction with Chris Lane’s URI lab and Gary Saunder’s UNB lab. A detailed look at what we have accomplished is found on the Algal Flora of Bermuda page. Currently, we are investigating the flora from the intertidal to deep subtidal waters of Bermuda, and the phylogenetic relationships of Bermuda with the Caribbean, southeastern USA and eastern Atlantic islands.

Systematics and Ecology of  Vaucheria species

A systematic/ecological investigation of an important mud stabilizing yellow-green alga, Vaucheria, involves collections and observations in various Connecticut freshwater wetlands, as well as the manipulation of cultures in the laboratory. Various species are collected from ponds, rivers, streams, marshes, and drainage ditches throughout the state, and cultured in the lab with the purpose of isolating clonal populations. Most of the species in this genus worldwide are broadly euryhaline, which means that, unlike most other living organisms, they can acclimate from freshwater to full-strength sea water or even greater salinity. Some of the research problems of interest to my lab, aside from basic taxonomy and distribution of local populations, include comparisons of reproductive behavior of Vaucheria under a variety of temperature and photoperiod conditions, chemical constituencies of the various species that reside sympatrically, and the effects of salinity, desiccation, extremes of temperature, hypoxia and anoxia, and environmental pollutants on the survival of the several species isolated from Connecticut habitats.
