  1. Abstract #OS42C-140 Background -Ten species of sea anemonee host anemonefish (Family Pomacentridae) : Cryptodendrum adaesivum, Entacmaea quadricolor, Macrodactyla doreensis, Heteractis magnifica, H. crispa, H. aurora, H. malu, Stichodactyla haddoni, S. gigantea, and S. mertensii. -The host anemones possess endosymbiotic zooxanthellae (dinoflagellates), so they must live in shallow, clear water -Anemones are brightly colored and their symbiosis with anemonefish makes them distinctive -Their habitat preferences and ecology are well known, but their distribution patterns have not been well studied -All 27 species of anemonefish are obligate symbionts of sea anemones during their entire lives except for a brief planktonic larval stage -Therefore, the geographic range of these fish is constrained by that of their host anemones -Unlike the fish, the anemones can exist without a fish symbiont in nature (with the exception of one species of anemone in one part of its range) -The anemone-anemonefish symbiosis is confined to the Indian and Western Pacific Oceans The Anemone-Anemonefish example:Anemonefish never occur in the absence of a host anemone, so can be used to extend analysis of anemone occurrence data – an example of Hexacorallia – Fishbase interaction (with environment!) Objectives and Methods -Determine which environmental variables characterize the habitat of the host sea anemones -Localities from which host sea anemones are known were gathered ultimately from the literature (assembled in Biogeoinformatics of Hexacorallia) -The environmental attributes associated with those localities were determined -Predict, based on the environmental attributes, where else the anemones might occur -Places characterized by the set of environmental attributes, but where there were no host anemone records, were identified -Assess the accuracy of the prediction by overlaying on the predicted distribution of anemonefishes -Localities from which anemonefish are known were taken from FishBase -Demonstrate a working ability to exchange data and information between two independent databases Why combine databases? -Relate organism distributions to habitat and environmental characteristics -Compare and combine distributions of taxonomically or functionally similar organisms -Create a product worth more than the sum of its parts Interoperability permits rapid, seamless integration of data and product preparation Synonymy -Until recently, the nomenclature of the host anemones was not standard. Using names in the published records results in more taxa, each with a smaller range -Syngraph finds the accepted name for an individual from any of the names in past literature, standardizing the names of host anemones and other species Funding NSF OCE 00-03970 (NOPP) to Daphne G.

  2. Environmental data associated with geo-referenced localities can be used for statistical habitat analysis and to predict occurrences -LOICZView geospatial clustering provides similarity analysis of environmental variables -This analysis used seven variables: Minimum Sea Surface Temperature, Minimum Salinity, Average Depth, Wave Height, Tidal Range, Ocean Color, and Reef Occurrences -All ten species of anemones were included in the overlay function -The areas included in the study are all shallow basins and coastal areas in the Indo-Pacific Basin. Resolution is the half degree cell. -These areas were subdivided into 16 clusters (Map A.), which were analyzed for anemone/anemonefish occurrence -The anemone overlay reveals that 77.7% of known host anemones occur in 8 of 16 clusters (Map B.) -The anemonefish overlay reveals that 83.7% of known anemonefish occur in 6 of 16 clusters (Map C.) A. B. C. Single Species Example -Macrodactyla doreensis -100% of geo-referenced points occur in these four clusters -Severe over prediction – most likely due to a small number of geo-referenced points -Eight records probably not enough to predict a distribution Tools: -LOICZView – K-means clustering tool for geo-spatial data http://www.palantir.swarthmore.edu/loicz/ -FishBase – Provided the anemonefish data http://www.fishbase.org/search.cfm -Syngraph – Used to link synonymous names of host anemones http://www.nhm.ku.edu/inverts/syngraph/ -Arcview GIS http://www.esri.com Conclusions -Two independent databases can share and exchange information and data to produce conclusions important to biodiversity and biogeography -Host sea anemones occur in a specific type of environment: they prefer high salinity, warm temperatures, clear water, and areas that reefs occur -The occurrence of soft-substrate anemones and reef-substrate anemones correlates with reef occurrence Acknowledgements Dr. Robert W.
