A revision of the genus Planinasus Cresson (Diptera, Periscelididae)
The New World species of the subgenera Allotrichoma Becker and Neotrichoma (new subgenus) (genus Allotrichoma) are revised. For phylogenetic perspective to this revision, we studied all genus-group taxa within the tribe Hecamedini and reassessed their cladistic relationships. Our phylogenetic study for taxa within the genus Allotrichoma was done at the species-group level, and we attempted to approach this globally by examining species from throughout the world and placing them into appropriate species groups. Within Allotrichoma, we recognize three subgenera. All known species from the New World are described with an emphasis on structures of the male terminalia, which are fully illustrated. We more than double the number of species known from the New World with six of 12 species in the subgenus Allotrichoma being described herein, and in a newly described subgenus, Neotrichoma, two of the three species from the New World are also described
Natural Disasters, Foreign Trade and Agriculture in Mexico
This work responds to the increasing global need of measuring and analyzing impacts, vulnerabilities and coping capacity of countries, regions and communities regarding climate change, extreme weather conditions, natural disasters and institutional constraints. The case of Mexico, analyzed in this work, provides lessons for further developing countries to assess natural disasters vulnerability, for making informed adaptation decisions and to optimize resources for reducing country and community vulnerability. This book’s analyses contribute to the current debate of the long-term economic impact of natural disasters (hurricanes, earthquakes, etc.), as well as offer an integral methodology c...

Seismicity of Central America
This book is the outcome of a careful and detailed study of earthquakes in Central America. It combines information from felt effects and instrumental recordings to reassess the location and size of events since the beginning of the instrumental era. Early sections describe the techniques used, with particular emphasis on the determination of earthquake magnitude. The largest section comprises detailed descriptions of more than 700 of the more significant earthquakes, many accompanied by maps of the felt effects. The main catalogue gives details of the location and size of more than 1800 events, with references to associated phenomena such as surface faulting, volcanism and tsunami generation.
