A Supermatrix Analysis Of Genomic, Morphological, And Paleontological Data From Crown Cetacea, Jonathan H. Geisler, Michael R. Mcgowen, Guang Yang, John Gatesy

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Cetacea (dolphins, porpoises, and whales) is a clade of aquatic species that includes the most massive, deepest diving, and largest brained mammals. Understanding the temporal pattern of diversification in the group as well as the evolution of cetacean anatomy and behavior requires a robust and well-resolved phylogenetic hypothesis. Although a large body of molecular data has accumulated over the past 20 years, DNA sequences of cetaceans have not been directly integrated with the rich, cetacean fossil record to reconcile discrepancies among molecular and morphological characters.

Results

We combined new nuclear DNA sequences, including segments of six genes (~2800 …

Distribution And Abundance Of The Kittlitz's Murrelet Brachyramphus Brevirostris In Selected Areas Of Southeastern Alaska, Michelle L. Kissling, Paul M. Lukacs, Stephen B. Lewis, Scott M. Gende, Katherine J. Kuletz, Nicholas R. Hatch, Sarah K. Schoen, Susan Oehlers

Wildlife Biology Faculty Publications

We conducted boat-based surveys for the Kittlitz’s Murrelet Brachyramphus brevirostris during the breeding season in southeastern Alaska from 2002 to 2009. We completed a single survey in seven areas and multiple annual surveys in three areas. Although surveys spanned a broad geographic area, from LeConte Bay in the south to the Lost Coast in the north (~655 km linear distance), roughly 79% of the regional population of Kittlitz’s Murrelet was found in and between Icy and Yakutat bays (~95 km linear distance). The congeneric Marbled Murrelet B. marmoratus outnumbered the Kittlitz’s Murrelet in all areas surveyed except Icy Bay; in …

Trade-Offs Between Gear Selectivity And Logistics When Sampling Nekton From Shallow Open Water Habitats: A Gear Comparison Study, Ronald Baker, Thomas J. Minello

Gulf and Caribbean Research

We compared logistical issues and the catch composition, density, and size structure of nekton samples collected with a drop sampler, benthic sled, and a fine mesh cast net in shallow non-vegetated habitats of Galveston Bay, Texas. Approximately 16 cast net replicates were collected and sorted for every one drop or benthic sled sample. The drop sampler collected the greatest number of species and provided the highest density estimates for the majority of crustaceans and small demersal fishes; the sled provided comparable density estimates for penaeids and small demersal nekton, while under-representing more mobile fishes. Densities of small benthic nekton were …

Odd Association And Range Extension Of Caligus Rufimaculatus Wilson, 1905; Caligidae, Siphonostomatoida, Copepoda, G.W. Benz, E.C. Greiner, S.R. Bowen, L. Goetz, N. Evou

Gulf and Caribbean Research

The Caligidae (Siphonostomatoida, Copepoda) comprises more than 465 parasitic species, over 250 of which belong to Caligus Müller, 1785 (Boxshall and Halsey 2004). Caligus spp. are primarily marine; but some representatives routinely inhabit brackish or fresh water (Margolis et al. 1975). Some Caligus spp. have been widely reported from several oceans, others have been documented from a single location, and a few have only been collected as free-swimming individuals not associated with a host (Margolis et al. 1975). Caligus spp. range from being stenoxenous to euryxenous, with most species infecting actinopterygians (Actinopterygii), a much smaller group exclusively or non-exclusively infecting …

Evaluating Methods For Optimizing Classification Success From Otolith Tracers For Spotted Seatrout (Cynoscion Nebulosus) In The Chesapeake Bay, Stacy Kavita Beharry

OES Theses and Dissertations

Identifying the natal sources of fish is an important step in understanding its population dynamics. Adult recruits are often sourced from multiple nursery areas, with good quality locations contributing disproportionately more fish to the adult stock. Because population persistence is strongly influenced by nursery habitat, methods that correctly identify the source of recruits are necessary for effective management. Within the last decade, otolith chemistry signatures have been increasingly used as a natural marker to delineate fish from a mixture of nursery sources. Despite the widespread use of otolith trace element and stable isotope ratios as habitat markers, the statistical approaches …

Emerging Issues And Methodological Advances In Fisheries Reproductive Biology, Nancy J. Brown-Peterson

Faculty Publications

Although incorporating detailed reproductive data into all stock assessments is not a practical goal, the need to understand how reproductive biology affects population productivity is being increasingly recognized. More research focused on reproductive biology-coupled with a shift towards a resilience perspective in fisheries science-is resulting in challenges to many long-held assumptions; the emergence of important new issues; and identification of the need to improve data and methods used in reproductive studies. Typically, data for reproductive studies are based on an assessment of gonadal development, which is most accurately evaluated with histology. This special section of Marine and Coastal Fisheries contains …

Comparative Phylogeography Of The Coral Triangle And Implications For Marine Management, Kent E. Carpenter, Paul H. Barber, Eric D. Crandall, Maria Carmen A. Ablan-Lagman, Ambariyanto Ambariyanto, Gusti Ngurah Mahardika, B. Mabel Manjaji-Matsumoto, Marie Antonette Junio-Menez, Mudjekeewis D. Santos, Craig J. Starger, Abdul Hamid A. Toha

Biological Sciences Faculty Publications

Extreme concentration of marine biodiversity and exploitation of marine resources in the Coral Triangle pose challenges to biogeographers and resource managers. Comparative phylogeography provides a powerful tool to test biogeographic hypotheses evoked to explain species richness in the Coral Triangle. It can also be used to delineate management units for marine resources. After about a decade of phylogeographical studies, patterns for theCoral Triangle are emerging. Broad connectivity in some species support the notion that larvae have maintained gene flow among distant populations for long periods. Other phylogeographic patterns suggest vicariant events resulting from Pleistocene sea level fluctuations, which have, at …

Two Distinct, Geographically Overlapping Lineages Of The Corallimorpharian Ricordea Florida (Cnidaria: Hexacorallia: Ricordeidae), H. Torres-Pratts, T. Lado-Insua, Andrew L. Rhyne, L. Rodríguez-Matos, N. V. Schizas

Arts & Sciences Faculty Publications

We examined the genetic variation of the corallimorpharian Ricordea florida; it is distributed throughout the Caribbean region and is heavily harvested for the marine aquarium trade. Eighty-four distinct individuals of R. florida were sequenced from four geographically distant Caribbean locations (Curaçao, Florida, Guadeloupe, and Puerto Rico). Analysis of the ribosomal nuclear region (ITS1, 5.8S, ITS2) uncovered two geographically partially overlapping genetic lineages in R. florida, probably representing two cryptic species. Lineage 1 was found in Florida and Puerto Rico, and Lineage 2 was found in Florida, Puerto Rico, Guadeloupe, and Curaçao. Because of the multi-allelic nature of the ITS …

Metals In Sediments And Clams From The Indian River Lagoon, Florida: 2006–7 Versus 1992, John H. Trefry, Robert P. Trocine

Ocean Engineering and Marine Sciences Faculty Publications

A 1992 survey of metal concentrations in sediments and clams from the Indian River Lagoon, Florida, was repeated during 2006–7. Concentrations of Cr, Ni, Se and V in sediments were at background values during both surveys with no indication of anthropogenic inputs. Average values for Ag, Cd and Zn in sediments, normalized to Al, were unchanged, but contamination was identified at several locations during both surveys. The proportion of sites with elevated values for sediment Cu, Hg and Pb increased between 1992 and 2006–7 from 22 to 65%, 9 to 35%, and 13 to 39%, respectively, with highest values near …

Distribution And Abundance Of Introduced Fishes In Florida's Charlotte Harbor Estuary, Charles F. Idelberger, Christopher J. Stafford, Sarah E. Erickson

Gulf and Caribbean Research

A growing number of non-native fishes have been introduced into Florida waters in recent years, yet little information has been available on their distribution and abundance in southwest Florida. The ichthyofauna of the Charlotte Harbor estuary, Florida, was intensively sampled from 1989 through 2007. We collected eight introduced fish taxa: African jewelfish (Hemichromis letourneuxi), blue tilapia (Oreochromis aureus), brown hoplo (Hoplosternum littorale), grass carp (Ctenopharyngodon idella), Mayan cichlid (Cichlasoma urophthalmus), sailfin catfishes (Pterygoplichthys spp.), spotted tilapia (Tilapia mariae), and walking catfish (Clarias batrachus). These fishes …

Distribution Of The Hermit Crabs Clibanarius Vittatus And Pagurus Maclaughlinae In The Northern Indian River Lagoon, Florida: A Reassessment After 30 Years, Christopher J. Kelly, Richard L. Turner

Ocean Engineering and Marine Sciences Faculty Publications

The present distribution of two hermit crabs, Clibanarius vittatus and Pagurus maclaughlinae, was assessed for comparison with a study done more than 30 yr ago on decapods of the region. Clibanarius vittatus presently occurs in low or moderate density only at Sebastian Inlet. Retreat of C. vittatus from sites that it formerly occupied is attributed to intolerance of its larvae to low salinities recorded in the lagoon during recent reproductive seasons. Pagurus maclaughlinae remains the most abundant and widespread hermit crab in the lagoon. Its present distribution seems unchanged from the reference study despite prolonged periods, sometimes years, during which …

Distribution And Conservation Status Of Antillean Manatees (Trichechus Manatus Manatus) In Honduras, Daniel González-Socoloske, Cynthia R. Taylor, Olivia R. Rendon Thompson

Faculty Publications

The Antillean manatee, Trichechus manatus manatus, is among the most threatened mammals in Honduras, yet the last published study is from 1980. Since then, the North Coast of Honduras has experienced rapid population growth and land cover change possibly causing habitat loss for manatees. We conducted aerial, boat, and interview surveys between 2005-2007 along the northern and remote eastern coasts of Honduras to assess the current status and distribution of manatees. In addition, we compiled all available data on manatee mortality from museum specimens, unpublished reports, and interviews to determine current threats. We averaged 1.2 manatee sightings per survey hour …

Disease Effects On Lobster Fisheries, Ecology, And Culture: Overview Of Dao Special 6, Donald C. Behringer, Mark J. Butler Iv, Grant D. Stentiford

Biological Sciences Faculty Publications

Lobsters are prized by commercial and recreational fishermen worldwide, and their populations are therefore buffeted by fishery practices. But lobsters also remain integral members of their benthic communities where predator-prey relationships, competitive interactions, and host-pathogen dynamics push and pull at their population dynamics. Although lobsters have few reported pathogens and parasites relative to other decapod crustaceans, the rise of diseases with consequences for lobster fisheries and aquaculture has spotlighted the importance of disease for lobster biology, population dynamics and ecology. Researchers, managers, and fishers thus increasingly recognize the need to understand lobster pathogens and parasites so they can be managed …

Behavior Constrains The Dispersal Of Long-Lived Spiny Lobster Larvae, Mark J. Butler Iv, Claire B. Paris, Jason S. Goldstein, Hirokazu Matsuda, Robert K. Cowen

Biological Sciences Faculty Publications

Behavior such as ontogenetic vertical migration (OVM) limits the transport of marine larvae with short pelagic larval durations (PLDs), but its effect on the supposed long-distance dispersal of larvae with long PLDs is unknown. We conducted laboratory tests of ontogenetic change in larval phototaxis and examined size-specific patterns of larval distribution in the plankton to characterize OVM in the Caribbean spiny lobster Panulirus argus during its long (6 mo) PLD. We then used a coupled biophysical model to explore the consequences of OVM and hydrodynamics on larval P. argus dispersal in the Caribbean Sea. Larvae reared in the laboratory were …

Estimation Of Short-Term Tag-Induced Mortality In Horseshoe Crabs Limulus Polyphemus, Jennifer Mattei, Mark Beekey, H. R. Potter, C. S. Bond, Alyssa Woronik, J. A. Roberts, K. A. Smith

Biology Faculty Publications

Horseshoe crabs Limulus Polyphemus range along the East Coast of the United States and over 150,000 of them have been marked with U.S. Fish and Wildlife Service disk tags. It has been assumed that the tags do not harm the animals and are similar to common epibionts often found on the shells of the horseshoe crabs. We investigated whether newlv tagged adult female horseshoe crabs would exhibit higher short-term mortality rates than untagged adult females. All crabs were collected from a beach in Connecticut and then were transported to a laboratory for the experiment. Tagging involved drilling a small hole …

Due Diligence And Demographic Disparities: Effects Of The Planning Of U.S.- Mexico Border Fence On Marginalized Populations, J. Gaines Wilson, Jude A. Benavides, Karen Engle, Denise Gilman, Anthony Reisinger, Jessica Spangler, Joe Lemen

School of Earth, Environmental, & Marine Sciences Faculty Publications

In the buildup to the construction the U.S.-Mexico border fence by the United States Department of Homeland Security (USDHS), much attention was drawn to security, drug enforcement, and immigration issues. However, there was little quantitative analysis regarding which populations were most likely to be affected by the proposed fence. Using a geographic information system, we classified census blocks in Cameron County, Texas into one of two categories: either ‘fence’ or ‘gap’. A total of 14 demographic factors were tested for disparities between those living in gap areas and those living in areas exposed to the fence. Twelve of fourteen factors …

An In Situ, Individual-Based Approach To Quantify Connectivity Of Marine Fish: Ontogenetic Movements And Residency Of Lingcod, Mary Anne Bishop, Brad F. Reynolds, Sean P. Powers

University Faculty and Staff Publications

As modern fishery assessments change in an effort to be more accurate and encompass the range of potential ecosystem interactions, critical information on the ecology of species including life history, intra and inter-specific competitive interactions and habitat requirements must be added to the standard fishery-dependent and independent data sets. One species whose movements and habitat associations greatly affects exploitation patterns is lingcod, Ophiodon elongatus, which support an economically important fishery along the coastal waters of the Pacific Coast of North America. High site fidelity and limited movements within nearshore areas are hypothesized to have resulted in high catchability, a …

Deglacial Abrupt Climate Change In The Atlantic Warm Pool: A Gulf Of Mexico Perspective, Carlie Williams, Benjamin P. Flower, David W. Hastings, Thomas P. Guilderson, Kelly A. Quinn, Ethan A. Goddard

Marine Science Faculty Publications

During the last deglaciation, Greenland ice core and North Atlantic sediment records exhibit multiple abrupt climate events including the Younger Dryas cold episode (12.9-11.7 ka). However, evidence for the presence of the Younger Dryas in the Gulf of Mexico (GOM) and the relationship between GOM sea surface temperature (SST) and high-latitude climate change is less clear. We present new Mg/Ca-SST records from two varieties of the planktonic foraminifer Globigerinoides ruber (white and pink) to assess northern GOM SST history from approximately 18.4-10.8 ka. Thirty-five accelerator mass spectrometry (AMS) C-14 dates from Orca Basin core MD02-2550 provide excellent age control and …
