Symplectic Lefschetz fibrations with arbitrary fundamental groups

In this paper we give an explicit construction of a symplectic Lefschetz fibration whose total space is a smooth compact four dimensional manifold with a prescribed fundamental group. We also study the numerical properties of the sections in symplectic Lefschetz fibrations and their relation to the structure of the monodromy group.Comment: 45 pages, LaTeX2e. Minor mistakes corrected. New appendix by Ivan Smith added, proving the non-existence of SLF with monodromy contained in the Torelli grou

On the taxonomy of snakes in the genus Leptodeira, with an emphasis on Costa Rican species

Considerable confusion surrounds the taxonomy of snakes in the genus Leptodeira, which contains 12 currently recognized species. Herein I review the genus and recognize 15 species based on previously published morphological and genetic data. Easily recognized traits can be used to identify Costa Rican species of Leptodeira, and taxonomic insights into all species in the L. annulata-septentrionalis complex are discussed. Photographs of all currently recognized species and subspecies are included
