Introduction
I am passionate about conservation of biodiversity of freshwater ecosystems. My main research interests are Systematics, Evolution and Biogeography of free-living Cyclopoida (Copepoda). I have experience in projects focused analyzing community structure of zooplankton in priority conservation areas (v.gr. Chihuahuan Desert Springs) and analyzing large sets of data focused in species distribution and its conservation status (v.gr. crustaceans from the Yucatan Peninsula).

There is increasing evidence that a large proportion of freshwater (invertebrate) diversity occurs in peripheral aquatic habitats, such phytotelmata, water films on vegetation, wet mosses, leaf carpets, and humid soils. In comparison with the multitude of studies on aquatic systems, the number of studies on micro-crustaceans in terrestrial and semi-terrestrial habitats is limited. Nevertheless studies in the more cryptic habitats have contributed substantially to fundamental understanding of the biology of micro-crustaceans. This work aimed to explore the diversity of habitats colonized by copepods and other micro-crustaceans in the tropical forest of Mexico; including open water bodies, leaf litter, moist soil and phytothelmata. With this we aimed to understand the patterns of colonization of new habitats and the differences among them (morphological, genetic and species richness). This study stresses the need of studying peripheral habitats which could be used as an indicator of local diversity; as well the importance of including such habitats in the conservation efforts of Neotropical arthropod diversity.
Project
Our goal is gathering all published information in as many languages as possible on in order to produce an open access database that facilitate future research in subterranean aquatic environments. Data will be gather for all groups of animals. The geographical scope is global, and it covers all types of so-called subterranean habitats ranging from freshwater and marine caves to hyporheic and interstitial environments. The project is part of the MSCA-IF-2016 "ANCAVE: Anchialine caves to understand evolutionary processes" granted to Alejandro Martinez and hosted by Diego Fontaneto (IRSA-CNR, Verbania).
