Zoobenthophily: a new type of pollination for marine plants
Presented by Dr. Brigitta I. van Tussenbroek and M.Sc. and Ricardo Wong
Seagrasses are the founding species of the submersed marine meadows. Seagrass is the common name of an ecological group of angiosperms living in the sea. The seagrass meadows can be very extensive, like that of the image dominated by Thalassia testudinum in Xcalak, Mexican Caribbean. These meadows provide multiple ecosystem services; such as habitat provision, nutrient regulation, sand and beach stabilization and carbon sequestration. To date, not much is known as to how this group of angiosperms has managed to reproduce under the sea.
M. en C. Ricardo Wong
The Master in Sciences Ricardo Wong studied the biology degree at the UNAM Faculty of Sciences, in that same Institution he obtained the degree of Master of Sciences in Plant Biology. His master's thesis dealt with aspects of the reproductive biology in Manihot walkerae (Euphorbiaceae), an endemic and endanger of extinction species from northern of Mexico.
Since 1992, he has been part of the Plant Development laboratory of the Faculty of Science at UNAM. The laboratory's work deals with some aspects of the sexual reproduction of angiosperms, such as pollination, fertilization and seed development. Master Wong works on the project of sexual reproduction of aquatic plants (marine and freshwater).
He has participated in several research articles on the subject, most notably the last one (published in nature communications), which describes the first report of zoophilic pollination in Thalassia testudinum, a seagrass from the Mexican Caribbean.
He advises undergraduate, master and doctoral students on the different techniques used in the laboratory. These consultancies are also provided to students or researchers from other University entities in the country. In addition, he collaborates in different research projects with various national and foreign researchers.
Dra. Brigitta I. van Tussenbroek
A Dutch national, Brigitta Ine van Tussenbroek is a graduate of the Faculty of Biology of the University of Utrecht. She completed her doctoral studies at the University of Liverpool, on the biology of giant kelp, Macrocystis pyrifera, in the Falkland Islands. She is currently a full researcher in the Reef Systems Unit, of the Institute of Marine Sciences and Limnology, of the National Autonomous University of Mexico (UNAM). She established the seagrass lab in 1990 when she joined as a researcher in the Reef Systems Unit, to initiate a new line of research on the ecology of marine vegetations in the Mexican Caribbean, with a special focus on seagrasses in reef systems. The importance of submerged vegetation to maintain the ecological balance of the Caribbean Sea is underestimated to date, and the study on its basic characteristics serves as the basis for assessing the vulnerability of this system to present and future pressures and disturbances. His research has produced more than 60 scientific articles, 6 book chapters and 1 book. He has directed more than 30 undergraduate, master's and doctoral students.
