WHAT ARE HEXACORALS? (to a biologist) 1. Cnidarians -- 2. Of class Anthozoawhich comprises two subclasses HEXACORALLIA (Zoantharia) and OCTOCORALLIA (Alcyonaria) Photos by George Miller

Biogeoinformatics of Hexacorals (http://www.kgs.ku.edu/Hexacoral/) An on-line information resource system that consists of two interactive databases one dealing with taxonomy and biogeography of hexacorals (corals, sea anemones, and their allies) one dealing with environmental information for the marine environment both served and linked by front ends offering user support for searching, analyzing, and downloading the data

SOMETHING ABOUT THE STRUCTURE AND CONTENTS OF “HEXACORAL” SOMETHING ABOUT HOW MY COLLABORATORS AND I USE IT Technical details: Oracle, ColdFusion, ArcIMS Three instances – present, past, and future
9
973 genera and 7706 binomens and trinomens 2620 original descriptions 2772 valid species 2487 type specimen lots (on line; nearly as many to be entered) 5316 images Literature- derived, specimen- based taxonomic and distributional data Holdings are most complete for the soft- bodied taxa, but data on Scleractinia are expanding rapidly and in coordination with NMITA

TAXONOMIC SEARCH
14
* * * THE BASIC INFORMATION
15
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
16
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.
17
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
18
A RESEARCH TOOL to predict habitats that might be vulnerable to invasion to know where to conduct field work
19

INITIAL SEARCH PARAMETERS
21
The combined search page yields an extended form of the “Hexacoral” species data link page
22
Joint search products Classification from Hexacoral Images from NMITA
23
Joint search products “Hexacoral” dynamic location maps of NMITA fossil occurrences NMITA stratigraphy
24
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
26
An On-line Atlas of Marine Diversity Fish Net, and a growing inventory of others
27
A biogeographic tale of two taxa (in three databases) Peder Sandhei Jay Baker (DBI00-97223)
28
10 SPECIES OF HOST ANEMONES
29
Anemones of most host species seldom occur without fish symbionts Anemonefish never occur without a host anemone (in nature)

TEST FOR ACCURACY

“NOTHING YET”
35
1872-1876 University of Kansas Digital Library Initiative to DGF, R. W. Buddemeier, S. Goodwin Thiel, with collaboration of J. Wood
36
Sea anemones were collected from about 31 of 504 stations 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 RESEARCH OBJECTIVE: REASSEMBLE NET CONTENTS
37
Stations will be 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
38
Data recorded for each station are being linked to user- selectable data on recent environmental conditions from the Hexacoral 30’ database (>200 variables) = 24.9 o C
39
To test for quality and consistency of both and provide temporal and spatial environmental connections RESEARCH OBJECTIVE: COMPARE EMPIRICAL WITH MODELED DATA -- Reynolds 2 o (1854-2002) and Hadley Centre 1 o (1871- 2002) reconstructed monthly SST averages include the Challenger years
40
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
41
Northern Hemisphere Average Surface Temperature 1000 1400 1200160018002000 0 1 2 Year Mann et al. (1999) GRL 26:759-762 °C 1998 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
42
Endosymbiotic dinoflagellates = Symbiosis break-down is a sign of stress (e.g. abnormally high or low temperature or salinity) BLEACHING
44
it would take A LOT of heat to warm the adjacent waters sufficiently for them to be hospitable to reef-forming corals No because shallow seas in the immediately adjacent higher latitudes have little suitable substrate And that’s not all…………
45
In 150 years, humans have driven atmospheric composition well outside the stable multi-million year range of oscillation Vostok ice core records
49
So, temperature is making equatorial latitudes inhospitable to reef-forming corals, but higher latitudes have too little calcium carbonate for them IN 50 YEARS
