Description:

Lingula reevii is an inarticulated brachiopod that is listed as a species of concern within Kāne'ohe Bay, Hawaii. The abundance of L. reevii throughout Kāne'ohe Bay has been decreasing since it was first studied in 1969, causing NOAA to add it to the Species of Concern list in 2004. In this study, L. reevii was genetically sequenced and compared to similar species in a phylogenetic tree. The data clearly showed that L. reevii was genetically distinct from the other species included in the tree. Field observations were conducted to determine if the abundance of L. reevii was decreasing and if a decrease could be caused by environmental factors such as salinity, pH, temperature, and sediment grain size. Transect surveys were performed at 11 sites throughout the bay. A general linear model was used to see if these factors were statistically significant. The effects of salinity, pH and the two factors combined were all determined to be significant. This study was unable to compare the abundance of L. reevii found in past years' studies because the study methods were not analogous. Future management efforts should include standardizing survey methods and using genetic analysis to compare populations from Hawaii to those in Japan and Indonesia. Also, to assess variability within the Hawaiian population as well as increasing the sample size to improve the length equation.
