Endangered endemics, clonal invaders, parasites and ancient plant populations

Dr. Lua Lopez Perez, Binghamton University, SUNY

Eco-evolutionary dynamics refers to how ecological environments have evolutionary consequences for organisms. Even macroevolutionary dynamics are the long-term result of short-term ecological interactions. Here I present results from several research projects that looked at the interplay between ecology and evolution in various systems highlighting the pivotal role that ecological phenomena have in the species evolutionary history and therefore in the species genetic make up. Namely I will focus on the following questions: Do life history traits impact the evolutionary potential of endemic species?, Can clonality increase the invasiveness of an alien species?, Can we find signatures of host specificity in generalist parasites? And, can we identify genetic changes across time and space associated with environmental changes?

Public Presentation:  Charleston’s Deep-Sea Coral Reef Discovery

Dr. Sandra Brooke, Marine Biologist, Florida State University

Dr. Sandra Brooke (Florida State University) studies deep-sea coral ecology and is one of a team of scientists working on the federally-funded ‘Deep Search’ project. This team is tasked with exploration and research of sensitive ecosystems, such as deep-sea corals, in areas that are open to future energy activity off the southeastern US. Information from ‘Deep Search’ will help inform management of these ecologically valuable habitats.

Dr. Brooke will provide an overview of the biology, ecology and conservation of deep-sea coral ecosystems.  She will discuss her participation in the exploration of the recently discovered 85-mile long deep-sea coral reef about 160 miles off Charleston’s coast.  Dr. Brooke’s first-hand account of the exploration will include images and descriptions of this newly explored coral reef.

New perspectives on an ancient association: microbial symbionts and coral reef sponges

Christopher Freeman, Department of Biology, College of Charleston

Sponges are prolific filter feeders, but their success across reefs in the Caribbean may also be linked to complex associations with microbial symbionts. Using manipulative field experiments, stable isotope analysis, and the characterization of sponge microbiomes, I am investigating how these associations influence host resource use. Recent work has shown that microbial symbionts allow sponges to exploit new sources of carbon and nitrogen on these reefs. In addition, results show a high degree of host specificity in these
microbial symbiont communities.  This talk will highlight how these symbionts benefit their hosts, how this benefit varies across sponge species, and the role that these symbioses may be playing in the success of sponges within the Caribbean.
