Occurrence Of Larval And Juvenile Fish In Mangrove Habitats In The Sian Ka'an Biosphere Reserve, Quintana Roo, Mexico, Matthew Campbell, Kim Withers, James Tolan

Gulf and Caribbean Research

Mangrove forests are ubiquitous in low lying coastal areas of tropical and subtropical zones of the world, including the lagoons of the Sian Ka’an Biosphere Reserve, Quintana Roo, Mexico. Mangroves are habitat for juvenile fish of both oceanic and estuarine origin (Vásquez-Yoemans 1992, Vásquez-Yoemans et al. 1992, Laegdsgaard and Johnson 1995). Development of the Caribbean coast of Mexico north and south of the Sian Ka’an Reserve is in large part focused on tourism-related endeavors such as destination resorts, scuba diving and fishing. While some of the development is innocuous, land acquisition for development of resorts has fragmented mangrove habitats in …

Carpoapseudes Heardi N. Sp. (Tanaidacea: Apseudomorpha) From Caribbean Waters Near Tobago, Tom Hansknecht, Katia Christol Dos Santos

Gulf and Caribbean Research

Carpoapseudes heardi n. sp. is described from samples collected from depths of 421 and 537 m off Tobago and is the first Caribbean record for the genus. The new species bears a resemblance to Carpoapseudes serratospinosus Lang, 1968 and other related species in the shortened dactylus unguis combination of pereopod 1, but has parallel eyespines like Carpoapseudes bacescui Guţu, 1975 and Carpoapseudes simplicirostris (Norman and Stebbing, 1886). Other diagnostic characters include pereopods 2 and 3 with basal spurs, labrum with paired lobes, labial palp with two terminal setae, maxillipedal bases with outer crenulations, and pleopods with 1-articled rami. It was …

Otolith Chemistry Indicates Population Structuring By The Antarctic Circumpolar Current, Julian R. Ashford, Cynthia M. Jones, Eileen E. Hofmann, Inigo Everson, Carlos A. Moreno, Guy Duhamel, Richard Williams

CCPO Publications

Large-scale transport of seawater in ocean currents may generate spatially complex population structure through the advection of life stages of marine fish species. To test this, we compared the chemistry of otolith nuclei from Patagonian toothfish (Dissostichus eleginoides), presently managed as spatially discrete Populations corresponding to fishing management areas along the Antarctic Circumpolar Current (ACC), which transports water eastward around the Southern Ocean. The chemistry of otolith nuclei, laid down during early life, differed significantly between fishing areas Off South America and the Antarctic and between some Antarctic areas. However, we found significant discrepancies from expectation for a …

Evidence Of Self-Correcting Spiral Flows In Swimming Boxfishes, I. K. Bartol, M. S. Gordon, P. Webb, D. Weihs, M. Gharib

Biological Sciences Faculty Publications

The marine boxfishes have rigid keeled exteriors (carapaces) unlike most fishes, yet exhibit high stability, high maneuverability and relatively low drag given their large cross-sectional area. These characteristics lend themselves well to bioinspired design. Based on previous stereolithographic boxfish model experiments, it was determined that vortical flows develop around the carapace keels, producing self-correcting forces that facilitate swimming in smooth trajectories. To determine if similar self-correcting flows occur in live, actively swimming boxfishes, two species of boxfishes (Ostracion meleagris and Lactophrys triqueter) were induced to swim against currents in a water tunnel, while flows around the fishes were quantified …

Rapid Evolution In Introduced Species, ‘Invasive Traits’ And Recipient Communities: Challenges For Predicting Invasive Potential, Kenneth D. Whitney, Christopher A. Gabler

School of Earth, Environmental, & Marine Sciences Faculty Publications

The damaging effects of invasive organisms have triggered the development of Invasive Species Predictive Schemes (ISPS). These schemes evaluate biological and historical characteristics of species and prioritize those that should be the focus of exclusion, quarantine, and/or control. However, it is not clear how commonly these schemes take microevolutionary considerations into account. We review the recent literature and find that rapid evolutionary changes are common during invasions. These evolutionary changes include rapid adaptation of invaders to new environments, effects of hybridization, and evolution in recipient communities. Strikingly, we document 38 species in which the specific traits commonly associated with invasive …

Habitat Condition And Associated Macrofauna Reflect Differences Between Protected And Exposed Seagrass Landscapes, Chet F. Rakocinski, Cynthia A. Moncreiff, Mark S. Peterson, Katherine E. Vanderkooy, Todd A. Randall

Gulf and Caribbean Research

Seagrass landscape configurations associated with different physical settings can affect habitat-structure and plant-animal relationships. We compared shoal grass (Halodule wrightii) habitat and macrofaunal variables between two fragmented seagrass landscapes at barrier-island locations subject to different disturbance regimes. Five seagrass habitat variables including above ground biomass (AGB), shoot number, per shoot biomass, epiphyte biomass and below ground biomass (BGB), differed significantly between the island landscapes. Per shoot biomass and epiphyte biomass also varied significantly over the seagrass growing season; and epiphyte biomass showed a strong landscape-time interaction. Abundances of microgastropods normalized to AGB differed significantly between landscapes. An inverse …

Seasonal Patterns Of Juvenile Fish Abundance In Seagrass Meadows In Teague Bay Bank Barrier Reef Lagoon, St. Croix, U.S. Virgin Islands, Ivan Mateo, William J. Tobias

Gulf and Caribbean Research

Considerable knowledge has been gained regarding fish use of nearshore habitats such as seagrass meadows or mangrove lagoons in the Caribbean (e.g., evaluation of nursery value, trophic linkages). However, few studies have been conducted on fish recruitment to seagrass habitat around the Caribbean. Juvenile reef fish in seagrass meadows at Teague Bay, St. Croix, U.S. Virgin Islands were surveyed from October 1998 through September 1999 using a visual census technique. Grunts (Haemulidae) were the most abundant juveniles observed (60% of all fish), followed by wrasses (Labridae, 20%) and parrotfishes (Scaridae, 13%). French grunt, Haemulon flavolineatum, were the most numerous …

An Unusual Reaction And Other Observations Of Sperm Whales Near Fixed-Wing Aircraft, Mari A. Smultea, Joseph R. Mobley Jr., Dagmar Fertl, Gregory L. Fulling

Gulf and Caribbean Research

Reported behavioral reactions by sperm whales to aircraft are sparse, highly variable, and largely anecdotal as summarized below. Observers since the whaling era began have noted that sperm whales tend to be skittish (Whitehead 2003). When documented, sperm whale reactions to both planes and helicopters range from no reaction (Clarke 1956, Gambell 1968, Green et al. 1992) to reactions such as increased surface intervals and dramatic behavioral changes (Clarke 1956, Fritts et al. 1983, Mullin et al. 1991, Würsig et al. 1998, Richter et al. 2003, 2006). Given the lack of supporting data for either case, it is important that …

Documentation Of A Gulf Sturgeon Spawning Site On The Yellow River, Alabama, Usa, Brian R. Kreiser, J. Berg, M. Randall, F. Parauka, S. Floyd, B. Young, K. Sulak

Gulf and Caribbean Research

The Gulf Sturgeon Recovery Plan (USFWS, GSMFC and NMFS 1995) stressed the need to provide maximum protection to Gulf sturgeon spawning habitat. The approach employed by various Gulf sturgeon researchers, including ourselves, to document spawning has been to identify potential spawning habitat on the basis of physical characteristics and/or tracking data, collect eggs, and then raise the eggs in the laboratory until the point where the larval fish can be identified (e.g., Marchant and Shutters 1996, Sulak and Clugston 1998, 1999). However, collecting eggs in any appreciable number is usually difficult, and these eggs may not always be viable upon …

Absorption Spectral Slopes And Slope Ratios As Indicators Of Molecular Weight, Source, And Photobleaching Of Chromophoric Dissolved Organic Matter, John R. Helms, Aron Stubbins, Jason D. Ritchie, Elizabeth C. Minor, David J. Kieber, Kenneth Mopper

Chemistry & Biochemistry Faculty Publications

A new approach for parameterizing dissolved organic matter ( DOM) ultraviolet-visible absorption spectra is presented. Two distinct spectral slope regions ( 275-295 nm and 350-400 nm) within log-transformed absorption spectra were used to compare DOM from contrasting water types, ranging from wetlands (Great Dismal Swamp and Suwannee River) to photobleached oceanic water ( Atlantic Ocean). On the basis of DOM size-fractionation studies ( ultrafiltration and gel filtration chromatography), the slope of the 275-295- nm region and the ratio of these slopes (S_R; 275-295- nm slope : 350-400- nm slope) were related to DOM molecular weight ( MW) and …

Swimming Dynamics And Propulsive Efficiency Of Squids Throughout Ontogeny, Ian K. Bartol, Paul S. Krueger, Joseph T. Thompson, William J. Stewart

Biological Sciences Faculty Publications

Synopsis Squids encounter vastly different flow regimes throughout ontogeny as they undergo critical morphological changes to their two locomotive systems: the fins and jet. Squid hatchlings (paralarvae) operate at low and intermediate Reynolds numbers (Re) and typically have rounded bodies, small fins, and relatively large funnel apertures whereas juveniles and adults operate at higher Re and generally have more streamlined bodies, larger fins, and relatively small funnel apertures. These morphological changes and varying flow conditions affect swimming performance in squids. To determine how swimming dynamics and propulsive efficiency change throughout ontogeny, digital particle image velocimetry (DPIV) and kinematic …

Preliminary Survey Of Fish Community Composition In Seagrass Habitat In Two Back-Reef Lagoons Of The Southern Mexican Caribbean, Lauren A. Yeager, J. Ernesto Arias-Gonzalez

Gulf and Caribbean Research

Little is known about seagrass fish communities in the southern Mexican Caribbean. Diurnal and nocturnal fish community structure in seagrass habitat were compared between back-reef lagoons using a visual census technique in a natural protected area within a national park (Xcalak) and an unprotected area (Mahahual). Seagrass fish communities differed significantly between the two locations in the daytime and Xcalak supported greater total fish densities. Species richness did not differ statistically between locations. Observed nighttime fish communities were characterized by low species richness and low fish abundance when compared to diurnal communities. Heavy tourist use and coastal development may have …

Shell Utilization Pattern By The Hermit Crab Isocheles Sawayai Forest And Saint Laurent, 1968 (Anomura, Diogenidae) From Margarita Island, Caribbean Sea, Venezuela, Lee A. Galindo, Juan A. Bolanos, Fernando L. Mantelatto

Gulf and Caribbean Research

Isocheles sawayai is a hermit crab that is occasionally mentioned in the literature, and recently its distribution was extended to Venezuelan waters. Because no information on the biology and shell use patterns of this species inhabiting Caribbean waters is available, we provide the first information on shell occupation patterns of I. sawayai from Venezuela. Specimens were collected monthly from January to December 2000 along the sandy shore of Margarita Island, Venezuela. The 942 specimens collected showed different shell use patterns between the sexes and according to the reproductive condition of the females. The gastropods Leucozonia nassa (37.37%), Engoniophos unicinctus (25.37%), …

First Record Of Ceratapsis Monstrosa, A Larval Oceanic Penaeoid Crustacean, From The Gulf Of Mexico, James S. Franks, Adrienne Russell Flowers

Gulf and Caribbean Research

The genus Cerataspis (Gray, 1838) (Crustacea, Decapoda), assigned to the Penaeoidea by Burkenroad (1936) and Heegaard (1966), has circumglobal distribution between 40ºN and 40ºS (Morgan et al. 1985) and is represented in the Atlantic Ocean by two rarely collected species, C. monstrosa and C. petiti. Descriptions of both species are based on the larval forms since their adult form remain undescribed (Morgan et al. 1985). Although the larval development of Cerataspis is described by five mysis stages (I-V) (Heegaard 1966), the large larva is very un-mysid like and appears more like that of a megalops with the abdomen bend …

Behavior Of An Escolar Lepidocybium Flavobrunneum In The Windward Passage As Determined By Popup Satellite Archival Tagging, D.W. Kerstetter, P.H. Rice, E.D. Prince

Gulf and Caribbean Research

In June 2003, fisheries research was conducted in the Windward Passage using a chartered commercial pelagic longline vessel (Rice and Snodgrass 2003). This paper describes the habitat use by an escolar in this location tagged with a pop-up satellite archival tag (PSAT) that remained attached to the fish for 14 d. Data recovered from the PSAT were used to directly document diel vertical migration and ambient temperature range for the first time in a mesopelagic teleost.

An Analysis Of Demographic Disparities Associated With The Proposed U.S.-Mexico Border Fence In Cameron County, Texas, J. Gaines Wilson, Jude A. Benavides, E. Anthony Reisinger, Joseph Lemen, Zachary Hurwitz, Jessica Spangler, Karen Engle

School of Earth, Environmental, & Marine Sciences Faculty Publications

Introduction: The United States Department of Homeland Security (DHS) plans to install a fence along the U.S.-Mexico border by late December 2008. While much attention has been drawn to the environmental, social and political issues surrounding the fence, analysis of demographic data on the populations that will be directly affected has been limited. This paper utilizes geographic information systems (GIS) and U.S. Census Bureau data with the objective of understanding the underlying demographics in areas along the proposed Rio Grande Valley section of the border fence located in Cameron County, Texas.

Historical Datasets Of Dugong (Dugong Dugon) Observations In The Kimberley Region Of Western Australia - Data Report - Report No. 2008-03, David K. Holley, R. I.T. Prince

Research outputs pre 2011

Research Need and Objective :

Many sections of the northern WA coastline have become heavily industrialised in the last three decades particularly throughout the Pilbara region where offshore and onshore oil and gas exploration and processing facilities are abundant. There have been recent moves to develop similar industry along the Kimberley coast to access the Browse Basin, a 140,000 Km2 offshore gas field approximately 300km off the Kimberley Coast. This has resulted in extensive debate and the need to define the natural values of this region, which is considered to be one of the world’s most ecologically diverse (WWF 2008). …

Wind, Waves, And Wing Loading: Their Relative Importance To The At-Sea Distribution And Movements Of North And Central Pacific Albatrosses, R M. Suryan, D J. Anderson, Scott A. Shaffer, D D. Roby, Y Tremblay, D P. Costa, F Sato, K Ozaki, G Balogh

Faculty Publications, Biological Sciences

Among the varied adaptations for avian flight, the morphological traits allowing large-bodied albatrosses to capitalize on wind and wave energy for efficient long-distance flight are unparalleled. Consequently, the biogeographic distribution of most albatrosses is limited to the windiest oceanic regions on earth; however, exceptions exist. Species breeding in the North and Central Pacific Ocean (Phoebastria spp.) inhabit regions of lower wind speed and wave height than southern hemisphere genera, and have large intrageneric variation in body size and aerodynamic performance. Here, we test the hypothesis that regional wind and wave regimes explain observed differences in Phoebastria albatross morphology and we …

Project Limulus: What Long-Term Mark/Recapture Studies Reveal About Horseshow Crab Population Dynamics In Long Island Sound, Mark Beekey, Jennifer Mattei

Biology Faculty Publications

Project Limulus is a long-term study of the population dynamics of the horseshoe crab population in Long Island Sound (LIS). We have tagged over 20,000 spawning adults from >20 beaches ranging from Greenwich to Stonington, CT since 1997. Cumulative recapture rates have reached 9%. On average 90% of the crabs are recaptured within a few miles of their original tag site within the first season. Between seasons, on average, 45% of crabs are recaptured within the same locality of where they were tagged. Of all recaptures, 99% of recaptured individuals are found within LIS. This past year we expanded the …
