Overview of session theme:<\/strong>
Perennial freshwater habitats are extremely scarce in the Sonoran Desert, and consist mainly of isolated springs, pools (tinajas), and oases fed by groundwater. Despite wide recognition of their importance to cultural institutions and terrestrial plants and animals, relatively little is known about aquatic biodiversity in these oases. While biodiversity surveys for certain taxa have been done in some oases (e.g. aquatic animals in oases of Sonora), the search for broader ecological patterns across the oases of Sonora and the Baja California peninsula is still in its infancy. Perhaps even less is known about the hydrological processes that provide the lifeblood of these systems.
The goals of this session are to:<\/p>\n

(1) synthesize existing research on aquatic species in the oases of Baja and Sonora
(2) identify biological knowledge gaps (e.g. taxonomic groups)
(3) determine what (if any) hydrological studies have been done
(4) explore ideas for oasis conservation planning within and across regions
(5) develop research collaborations for future work
(6) determine how to best share data (or even locations of oases)<\/p>\n

Overview of session discussion:<\/strong>
Session timeline:
15 minute introduction
30 minute small group session
30 minute group discussion
15 minute wrapup and synthesis
Michael Bogan gave a powerpoint introduction to oases in the Sonoran Desert and articulated the goals and expected outcomes of the session. We clarified the definition of oases as any spring-fed permanent waterbody in the Sonoran Desert region.
We split into six small groups, each associated with a theme: Plants, Fish, Amphibians & Reptiles, Hydrology, Birds and Mammals, and Fuentes de Agua en Isla Tibur\u00f3n. The groups were instructed to address the goals outlined during the introduction. Small group work lasted 30minutes and concluded with presentations by each of the groups.
Common themes in the group discussions included a need for basic information on species occurrence and abundance and a better understanding of oasis hydrology. Common threats included invasive species, human alteration, and mining. Groups proposed assembling a list of oasis locations and known species. Details of the group discussions follow under \u201cDetailed Notes.\u201d
Action items discussed during the session:<\/strong><\/p>\n

1. Create a list of individuals who are interested in continuing the conversation about Sonoran Desert oases.
2. Identify individuals to write a synthesis paper on what is known about Sonoran Desert oases and identify gaps in our knowledge.
3. Compile oasis locations and species lists on GoogleDocs or other electronic platform.<\/p>\n
