SCHWEITZER Research Associate, Section of Invertebrate Paleontology; Department of Geology, Kent State University Stark Campus, Canton, OH 44720 ([email protected]) ABSTRACT Five previously undescribed decapod taxa have been collected from lower upper Miocene rocks of the Puerto Madryn Formation, Peninsula Valdes region, Chubut Province, Patagonia, Argentina. New species include Osachila valdesensis, Rochinia boschii, Romaleon parspinosus, Panopeus piramidensis, and Ocypode vericoncava. Chaceon peruvianus and Proterocarcinus latus are also reported from the unit, in addition to two indeterminate xanthoid species. Assignment of fossil taxa to genera within the Panopeidae Ortmann, 1893, is difficult due to the marked similarity in dorsal carapace characters among several genera. Panopeus whittenensis Glaessner, 1980, is herein referred to Pakicarcinus Schweitzer et al., 2004. The Puerto Madryn Formation exposed near Puerto Piramide contains three distinct Facies Associations (1-3), each associated with specific paleoecological and paleoenvironmental conditions, and which recur throughout the section and represent trangressive systems tract (TST) deposits and highstand systems tract (HST) deposits. Within Facies Association 1, near the base of the section at Puerto Piramide, three paleosurfaces containing invertebrate fossils in life position are exposed and have been carefully mapped in plan view. -
Biodiversity
Papahānaumokuākea Marine National Monument Biodiversity Management Issue Managers require adequate information on the status of biodiversity in order to effectively protect resources of the Papahānaumokuākea Marine National Monument (PMNM or Monument). Description The Monument is the single largest conservation area under the U.S. flag, encompassing 137,797 square miles of the Pacific Ocean. The reefs of the Monument are considered to be in nearly pristine condition. Comprehensive information on the biodiversity of the Monument is needed in order to protect these valuable resources. As an example of how little is known about biodiversity in the Monument, a 2006 Census of Marine Life cruise which focused on non-coral invertebrates and algae found hundreds of new records and several new species. Given that this work occurred only within three miles of French Frigate Shoals, it is reasonable to expect that a similar intensive effort at other areas of the Monument would likely yield comparable results. Furthermore, to date much of the work that has been completed has been focused on shallow-water (<100 ft.) reef ecosystems, research focused on underexplored habitats such as deep reefs, sand habitats, and algal beds will certainly also reveal new records and species. It is clear that much more effort needs to be put into establishing baseline biodiversity data as an essential first step to understanding the ecosystems of the Monument. Questions and Information Needs 1) What is the baseline biodiversity at different sites within the Monument? -

Conservation Strategies: Matching Science and Management THE 2007 HAWAI‘I CONSERVATION CONFERENCE Conservation Strategies: Matching Science and Management July 25-27, 2007 Hawai‘i Convention Center, Honolulu, Hawai‘i Sponsored by the Hawai‘i Conservation Alliance (HCA) Welcome to the 15th Annual Hawai‘i Conservation Conference (HCC). This is the largest annual gathering of people actively involved in the protection and management of Hawai‘i’s natural environment. The purpose of your conference is to facilitate information transfer and interaction among natural resource managers and the scientific community. It is your opportunity to share experiences and ideas on a wide range of conservation issues within the 2007 theme of Conservation Strategies: Matching Science and Management. Mahalo nui loa for your continued participation and support of the activities of the HCA. This year is a landmark year for the Hawai‘i Conservation Alliance. It is the 15th anniversary of our conference and by far our largest one to date. As of July 1, twenty percent more registrations were received than at that date in 2006. There is a similar increase in presentations to be run in three and four concurrent sessions. This year the conference theme is Matching Science and Management – straight to the very core of our activities. Presenters have been asked always to have management in mind. If management is not presented, you know what the first question should be! The committee also asked for paired presentations – a paper dealing with an aspect of science followed by a paper dealing with its management. There are also eleven symposia topping last year’s high of four. -

Measuring, Interpreting, and Responding to Changes in Coral Reefs: a Challenge for Biologists, Geologists, and Managers Caroline S
Measuring, Interpreting, and Responding to Changes in Coral Reefs: A Challenge for Biologists, Geologists, and Managers Caroline S. Rogers and Jeff Miller Abstract What, exactly, is a coral reef? And how have the world’s reefs changed in the last several decades? What are the stressors undermining reef structure and function? Given the predicted effects of climate change, do reefs have a future? Is it possible to “manage” coral reefs for resilience? What can coral reef scientists contribute to improve protection and management of coral reefs? What insights can biologists and geologists provide regarding the persistence of coral reefs on a human timescale? What is reef change to a biologist... to a geologist? Clearly, there are many challenging questions. In this chapter, we present some of our thoughts on monitoring and management of coral reefs in US national parks in the Caribbean and western Atlantic based on our experience as members of monitoring teams. We reflect on the need to characterize and evaluate reefs, on how to conduct high- quality monitoring programs, and on what we can learn from biological and geological experiments and investigations. We explore the possibility that specific steps can be taken to “manage” coral reefs for greater resilience. Keywords Monitoring • Random sampling • Marine protected areas • Biodiversity • Connectivity 12.1 Current State of Coral Reefs1 For the purposes of this paper, we define “true” coral reefs as rigid, topographically complex structures developed from carbonate accretion by corals and other cementing and calcifying organisms and the product of biological and geo- logical processes. This definition reflects comprehensive discussions in Buddemeier and Hopley (1988), Hubbard (1997), Hubbard et al. -

Darragh* and George W. Kendriek** ABSTRACT One scaphopod and 35 gastropod species are recorded from the Late Maastrichtian Miria Formation of the Carnarvon Basin, northwestern Australia. Preservation of the fossils suggests that the assemblage, which is inferred to contain herbivores, possible detrital feeders, graz.ers, predatory and ectoparasitic carnivores, is only partly representative of the original fauna. The original mineralogy of the shells has, in part, determined which mollusks have been preserved, their state at recovery, and whether or not they can be identified. Primary calcite has remained but argonite has been lost and partially replaced by secondary calcite. Six species are known only from internal moulds, Five new species - Conotomaria millacis sp. nov., Conolomaria (7) cypsela sp. nov., Leptomaria perallcisa sp. -
Sponge Contributions to the Geology and Biology of Reefs: Past, Present, and Future 5
Sponge Contributions to the Geology and Biology of Reefs: Past, Present, and Future 5 Janie Wulff Abstract Histories of sponges and reefs have been intertwined from the beginning. Paleozoic and Mesozoic sponges generated solid building blocks, and constructed reefs in collaboration with microbes and other encrusting organisms. During the Cenozoic, sponges on reefs have assumed various accessory geological roles, including adhering living corals to the reef frame, protecting solid biogenic carbonate from bioeroders, generating sediment and weakening corals by eroding solid substrate, and consolidating loose rubble to facilitate coral recruitment and reef recovery after physical disturbance. These many influences of sponges on substratum stability, and on coral survival and recruitment, blur distinctions between geological vs. biological roles. Biological roles of sponges on modern reefs include highly efficient filtering of bacteria- sized plankton from the water column, harboring of hundreds of species of animal and plant symbionts, influencing seawater chemistry in conjunction with their diverse microbial symbionts, and serving as food for charismatic megafauna. Sponges may have been playing these roles for hundreds of millions of years, but the meager fossil record of soft-bodied sponges impedes historical analysis. Sponges are masters of intrigue. They play roles that cannot be observed directly and then vanish without a trace, thereby thwarting understanding of their roles in the absence of carefully controlled manipulative experiments and time-series observations. Sponges are more heterogeneous than corals in their ecological requirements and vulnerabilities. Seri- ous misinterpretations have resulted from over-generalizing from a few conspicuous species to the thousands of coral-reef sponge species, representing over twenty orders in three classes, and a great variety of body plans and relationships to corals and solid carbonate substrata. -
Ichnology of Shallow Marine Deposits in the Miocene Chenque Formation of Patagonia: Complex Ecologic Structure and Niche Partitioning in Neogene Ecosystems
Asociación Paleontológica Argentina. Publicación Especial 9. Buenos Aires, 30-10-2003 ISSN 0328-347X IV Reunión Argentina de Icnología y II Reunión de Icnología del Mercosur: 85-95. Ichnology of shallow marine deposits in the Miocene Chenque Formation of Patagonia: complex ecologic structure and niche partitioning in Neogene ecosystems Luis A. BUATOIS1, Richard G. BROMLEY2, M. Gabriela MÁNGANO1, Eduardo BELLOSI3 and Noelia CARMONA1 Abstract. Exposures of the Lower Miocene Chenque Formation in central Patagonia contain superbly preserved ichnofaunas that allow detailed examination of cross-cutting relationships and tiering structure. This study is focused on lower shoreface deposits of the Borja sequence, exposed in coastal cliffs, in two localities near the city of Comodoro Rivadavia: Punta Delgada (south of Chubut Province) and Playa Las Cuevas-Punta Peligro (north of Santa Cruz Province). The ichnofauna is preserved in fine-grained silty sandstone, which intercalate with thin lenticular shell beds. The intervals analyzed are intensely biotur- bated with discrete traces superimposed on an undifferentiated background mottling. The ichnofauna is dominated by feeding traces of infaunal deposit feeders, such as Phycosiphon, Teichichnus, Helicodromites, Asterosoma, Schaubcylindrichnus, and Taenidium, but grazing trails of deposit feeders (e.g. Planolites, Scolicia), feeding traces of chemosymbionts (Chondrites), and dwelling traces of suspension feeders (e.g. Ophiomorpha, Palaeophycus) and deposit feeders (e.g. Rosselia) are present also. Associated body fossils include bivalves, echinoderms, bryozoans, serpulids, gastropods and sponges. Associated body fossils are bioeroded (Entobia, Rogerella, Gastrochaenolites). High degree of bioturbation together with high ichnodiversity, the lithofa- cies assemblage and variety of body fossils indicate slow or discontinuous sedimentation in well oxygenated open marine set- tings under normal salinity conditions.
