The course is aimed at graduate students, post-docs, or professionals who are interested in learning and applying knowledge about the biology, diversity and systematics of a fascinating and ecologically important but understudied phylum of marine invertebrates – the nemerteans (ribbon worms). The students participating in this course will:
- Learn how to collect nemerteans associated with shallow coral reefs, mangrove fouling communities, and macroalgae of the Bocas del Toro region
- Learn general biological characteristics of the group, major taxonomic subdivisions, and characters used for species identification and description
- Learn to collect and identify planktonic larvae of nemerteans
- Learn to preserve larval and adult nemerteans for subsequent morphological and molecular studies
Nemerteans are ubiquitous in marine communities worldwide; they are common and diverse, with ~1300 described species, ranging in length from a few millimeters to several meters (one species is officially the longest animal on Earth). Most are free-living predators, that attack and subdue their prey using an eversible proboscis and an impressive array of toxins. Some are parasites or egg predators of other marine invertebrates, including many commercially fished species of crustaceans. Nemertean larvae are very diverse and are commonly present in the plankton. Yet these beautiful and fascinating worms remain largely ignored even by invertebrate zoologists, in part because of their cryptic habits (many are nocturnal, and, in general, they are hard to find unless you know how to look), presence of numerous cryptic species (morphologically indistinguishable, but genetically distinct), and also because of the inherent difficulties associated with preservation and identification of soft-bodied organisms. The nemertean fauna of Bocas del Toro, Panama is very poorly known. Some 16 species are reported in the published literature (with many undescribed species), but recent sampling and DNA-barcoding suggests that the actual diversity is at least five times that number. This likely reflects the amount of undescribed diversity for this phylum worldwide.
This course will engage students in the real work of collecting, identifying and describing nemerteans. The course will last 10 days, with the first five days dedicated to collecting and learning about nemertean biology and the techniques to identify, preserve and characterize nemertean species (both in their larval and adult forms). Our time will be divided between field trips, lectures and laboratory exercises. Second half of the course will be dedicated to individual research projects (e.g. producing formal descriptions of local undescribed species, studying the embryonic and larval development, feeding habits or other aspects of biology, according to student interests). The course will conclude with student presentations of their research projects. For more information on nemerteans see: https://bocasarts.weebly.com/nemertean-tools.html
Application: Please e-mail your CV, 1 letter of recommendation, and a 1-2 page statement explaining your background and reasons for taking the course, to email@example.com before January 30th, 2018. Limit 12 students. To be considered for a need-based fellowship, applicants should send a description of their need, their efforts to obtain funding from other available sources, and a travel budget.

Cecili Barroso Mendes
Cecili Mendes is a PhD student at Universidade de São Paulo. Her main interest is Nemertean diversity and gene flow, specially how they are influenced by environmental factors and biogeographic barriers. Cecili's PhD project is focused on Seascape Genomics using Nemerteans and Polychaetes as biologic systems through Next generation sequencing tools. Cecili is also interested in the use of molecular tools for species delimitation and discovery of cryptic species among the Phylum Nemertea.
Christina Iris Ellison
Oregon University, United States
Christina recently completed a Bachelor’s degree in Marine Biology at the University of Oregon. She currently works in the Maslakova lab at the Oregon Institute of Marine Biology (OIMB), generating DNA sequence data from nemerteans to aid in diversity assessment of the phyla, and she was involved in creating the identification guide used in this workshop. She is interested in molecular biology and taxonomy, and their application in biodiversity assessment of marine organisms. She looks forward to working on a master’s thesis in the Maslakova lab starting this fall.
Christine Josee De Roux
Sarah Lawrence College, United States
Christine deRoux is a recent graduate of Sarah Lawrence College, and current student of Jon Norenberg at the Smithsonian Institute. Christine is interested in parasite biodiversity among the nemerteans as well as the group's deep systematics. More broadly, Christine aims to expand the pool of biotechnology available to systematists, through the generation of informative libraries as well as the development of computational biology software more apt to capture the effects of parasitism on evolution
Eduardo Enrique Zattara
Ed is currently an Adjunct Researcher at Argentina's National Council for Research and Technology (CONICET) working at the Institute for Biodiversity and Environmental Research located in the city of Bariloche, where he got his initial degree in Biology. He left the country for a decade to obtain a PhD in Behavior, Ecology, Evolution and Systematics at the University of Maryland, College Park, and later held postdoctoral positions at the Smithsonian Institution's National Museum of Natural History and Indiana University, Bloomington, before returning home. Ed's research experience explored a wide range of systems, including ecology of freshwater fisheries, evolution of regeneration in annelids and nemerteans, eco-evo-devo of horned beetles, pollinator decline, and the evolutionary consequences of somatic mutation in long lived and clonal organisms without early germline segregation. Despite this diversity in topics, Ed is arriving to Bocas wearing his Ribbon Worm hat, and interested in strengthening his knowledge about Nemertean systematics and his ties to this research community.

Jaime Alberto Gonzalez Cueto (born May 14, 1992), is a Biologist from Colombia. Currently works as a high school teacher, teaching Natural Science and Environmental Education. Jaime does research in Marine Biology, Zoology and Systematics (Taxonomy), He is interested in answering several research questions related to Nemertean species present in Colombia. Their most recent publication is “First record of Carcinonemertes conanobrieni (Nemertea, Carcinonemertidae), an egg predator of the Caribbean spiny lobster Panulirus argus, in the Caribbean Coast of Colombia”. In this paper, the authors make the first record of C. conanobrieni from all the Caribbean Sea (Carcinonemertes genus may cause a substantial decrease of the reproductive performance of the host, mainly crabs and lobsters).
Jose Elias Fernandez Alfaya
PhD in biological Science and Assitant Professor in Animal Diversity I from the National University of Patagonia San Juan Bosco, Puerto Madryn, Argentina. My research focuses on marine nemerteans biodiversity, a poorly studied taxa in Argentina. The main goal of my research is to characterize the nemertean fauna using morphological and molecular characters, and the phylogenetic relationships between species. Another major focus of my research is to study the ecological role of Nemerteans in the benthic trophic assemblees, with special attention to those species that live in symbiotic relationships with other invertebrates.

I am in the 1st year of a Master's degree in biological science at Hokkaido University, Japan. My research interest is systematics and evolutionary ecology of the Phylum Nemertea, in particulalr, Pilidiophora. There are some heteronemerteans getting very long body length, such as Lineus longissimus. One of my current research is to reveal why such heteroemerteans get so long, focusing on their life history traits. I am also working on taxonomy and phylogeny of Nemertea with morphological observation and molecular analysis.
