“…For example, the elemental composition of reef fish otoliths might differ between larvae whose development in MHI waters is burdened by coastal runoffs containing lead, herbicides, and several volcanism-specific elements (Spencer et al 2000, Sansone et al 2002, and larvae experiencing the relatively pristine oceanic environments of NWHI waters. Several accurate and precise techniques such as modern mass spectrometry (Campana et al 2000) exist for quantifying trace element signatures in the tiny otoliths of reef fish settlers.…”

The spatial distribution and magnitude of endemism in shallow-water (<18 m) reef fishes of the 10 Northwestern Hawaiian Islands (NWHI) are described in terms of occurrence, and numerical and biomass densities, using a series of diver-observation surveys conducted during September/October 2000, 2001. Based on species-presence in our surveys, we found endemism to be equal (20.6% using all available data) for fishes in the NWHI and the Main Hawaiian Islands (MHI; 20.9%). On average, percentage endemism was much higher based on the biomass (37%) and numerical densities (52%) of endemics, increased with latitude, and was especially pronounced at the 4 northernmost reefs that are the most ancient emergent geological features of the archipelago. Endemic reef fishes were appreciably smaller bodied than non-endemics within the NWHI. Median body size did not vary with latitude and longitude for either endemics or nonendemics, negating environmental effects. Reef fish populations at higher latitude reefs included larger proportions of young-of-year (YOY) recruits. YOY length frequencies did not differ for most species between northern and southern reefs, suggesting that a seasonal lag in spawning and recruitment at higher latitudes cannot explain the greater YOY densities observed there. Disproportionate recruitment at higher-latitude reefs may be related to better growth and survivorship after settlement onto reefs, higher levels of within-reef and regional reseeding at higher latitudes, or other factors. Resolution of these issues will be difficult, but it is profoundly important to the future siting of no-take Marine Protected Areas (MPAs) within the NWHI Coral Reef Ecosystem Reserve and to the rational conservation and management of reef fish resources throughout the Hawaiian Archipelago.

“…However, only a few studies have focused on stable Pb isotopes in biological samples to trace the anthropogenic origins of Pb (Kurkjian and Flegal, 2003). Previous studies have proven that the Pb isotopic composition of biological samples can provide a fingerprint for sources of Pb (Rabinowitz, 1995;Spencer et al, 2000;Manahan, 2000;Kurkjian and Flegal, 2003).…”

“…The original otolith digestion procedure used by Spencer et al [17] using heat lamps to dry down samples was modified to a procedure using microwave digestion. The new procedure allowed for 11 samples and one blank to be digested at a time and the digestion took less time than the previous method.…”

“…Lead isotopes in the microchemistry of otoliths were used by Spencer et al [17] on the basis of the difference in isotope signatures between petrol lead additives that contaminate the sediment and near-sediment water column in Kaneohe Bay, and the ambient near-shore lead isotopes that have naturally dissolved from the basaltic base rock of the island of Oahu, Hawai'i. The success of the lead isotope study in Hawai'i lead us to carry out a similar approach to the problem of site identification central to the management of L. campechanus.…”

U. This suite of elements was chosen because they were most likely to be present at oil and gas platforms in the metals and other materials used in artificial reefs, and in the circulating heavy "muds" used while drilling wells. A series of statistical analyses were performed to establish the statistical structure of the data. Linear and stepwise discriminant analyses were performed to show that by using subsets of all the elements measured, it was possible to discriminate among artificial reefs and oil and gas platforms at average misclassification rates of the order of 10%.
