Biogeoinformatics of Hexacorals (http://www.kgs.ku.edu/Hexacoral/) An on-line information resource system that consists oftwo interactive databases one dealing with taxonomy and biogeography of hexacorals (corals, sea anemones, and their allies) one dealing with environmental information for the marine environmentboth served and linked by front ends offering user support for searching, analyzing, and downloading the data
SOMETHING ABOUT THE STRUCTURE AND CONTENTS OF “HEXACORAL” Technical details: Oracle, ColdFusion, ArcIMS SOMETHING ABOUT HOW MY COLLABORATORS AND I USE IT Three instances – present, past, and future
Literature-derived, specimen-based taxonomic and distributional data 962 genera and 7664 binomens and trinomens 2592 original descriptions 2767 valid species 2439 type specimen lots (on line; nearly as many to be entered) 5374 images Holdings are most complete for the soft-bodied taxa, but data on Scleractinia are expanding rapidly and in coordination with NMITA

THE BASIC INFORMATION * * *
Syngraph a synonymy tool with both graphical and tabular outputs developed by Adorian Ardelean fully implemented for actinians being applied to other groups as the database expands
Occurrence records displayed on a map use symbols of a different color for each synonymous name. This function can be used for investigating whether a synonymy is justified.
For taxa with georeferenced records, a query of the companion global 30’ environmental database produces summaries of general environmental conditions for individual entries or a summary for the taxon
A RESEARCH TOOL to know where to conduct field work Simple statistics are used to identify areas of “core” environmental values and outliers to predict habitats that might be vulnerable to invasion
IMAGES original photomicrographs of type material illustrations from original descriptions original photos of type specimens
The combined search page yields an extended form of the “Hexacoral” species data link page

Joint search products “Hexacoral” dynamic location maps of NMITA fossil occurrences NMITA stratigraphy
Interoperation• allows users to o obtain and interrelate more data o analyze those data using more tools o formulate and address broad-scale questions• avoids duplication of effort in database entry• provides a double-check on data accuracy (aids in detecting errors, inconsistencies) and thereby improves data quality• increases accessibility and reaches a broader community, bridging bio- and geo-informatics

Sea anemones were collected from about 31 of 504 stations RESEARCH OBJECTIVE: REASSEMBLE NET CONTENTS Other databases contain data for other stations -- and those without certainly could use them This prototype will become a tool to link OBIS data, and will be extended to other expeditions
Stations are searchable by number, date, location, and in two map forms – scanned and hot-linked images of original charts, and ArcIMS to provide data on environmental variables from point samples and other sources Prototype example
Data recorded for each station are linked to user-selectable data on recent environmental conditions from the Hexacoral 30’ database (>200 variables) = 24.9o C
RESEARCH OBJECTIVE: COMPARE EMPIRICAL WITH MODELED DATA -- Reynolds 2o (1854-2002) and Hadley Centre 1o (1871-2002) reconstructed monthly SST averages include the Challenger years = 24.9o C To test for quality and consistency of both and provide temporal and spatial environmental connections
We know where animals live and have lived We know conditions characterizing those places We have forecasts of future conditions so we can predict what will (or will not) live in those places
In the space of 150 years, atmospheric temperatures have increased beyond the range of past natural variations and also beyond the range of uncertainty in those variations 2 Northern Hemisphere Average Surface Temperature 1998 1 °C 0 -1 1400 1000 1200 1600 1800 2000 Year Mann et al. (1999) GRL 26:759-762
Endosymbiotic dinoflagellates = Symbiosis break-down is a sign of stress (e.g. abnormally high or low temperature or salinity) BLEACHING
But wouldn't that be good for reefs?? No because • it would take A LOT of heat to warm the adjacent waters sufficiently for them to be hospitable to reef-forming corals • shallow seas in the immediately adjacent higher latitudes have little suitable substrate And that’s not all…………
In 150 years, humans have driven atmospheric composition well outside the stable multi-million year range of oscillation Vostok ice core records
So, temperature is making equatorial latitudes inhospitable to reef-forming corals, but higher latitudes have too little calcium carbonate for them IN 50 YEARS
