Response Of Large River Fishes To A Prolonged High Water Event In The Missouri River, Nebraska, Nicholas Paul Hogberg 2014 University of Nebraska - Lincoln

Response Of Large River Fishes To A Prolonged High Water Event In The Missouri River, Nebraska, Nicholas Paul Hogberg

Dissertations & Theses in Natural Resources

Regulation and modification of large rivers to accommodate human uses have been a root cause of freshwater biodiversity declines. The Missouri River is among the most drastically-altered large river systems in North America, with a series of mainstem impoundments in the upper watershed altering flow characteristics downstream, and channelization throughout the lower river homogenizing instream habitat and reducing off-channel habitat. Precipitation events during the winter and spring 2010-2011 caused flooding of the greatest magnitude and duration since reservoir completion. The large magnitude and long duration of this flood made it unlike any flood in recent history and provided a unique ...

Utilization Of The Invasive Alga Gracilaria Vermiculophylla (Ohmi) Papenfuss By The Native Mud Snail Ilyanassa Obsoleta (Say), Michele Guidone, Christine Newton, Carol S. Thornber 2014 Sacred Heart University

Utilization Of The Invasive Alga Gracilaria Vermiculophylla (Ohmi) Papenfuss By The Native Mud Snail Ilyanassa Obsoleta (Say), Michele Guidone, Christine Newton, Carol S. Thornber

Biology Faculty Publications

The recent invasions of the red alga, Gracilaria vermiculophylla, to the Atlantic and Eastern Pacific Oceans have the potential to significantly alter intertidal and subtidal soft sediment communities. In particular, G. vermiculophylla increases habitat complexity and provides a novel hard substrate in an otherwise two dimensional habitat. Following our observations that the native omnivorous mud snail Ilyanassa obsoleta utilizes G. vermiculophylla for egg capsule deposition, our field surveys demonstrated that the in situ abundance of egg capsules on G. vermiculophylla matched abundances on a native alga Ceramium virgatumandwere at least 11–50 times greater than on all other co-occurring macrophytes ...

1. Research on rare and threatened species is often limited by access to sufficient individuals to acquire information needed to design appropriate conservation measures. 2. Using a combination of data from pop-up archival transmitting (PAT) tags across multiple institutional programmes, movements and habitat use of endangered smalltooth sawfish, Pristis pectinata were determined for animals from southern Florida and the Bahamas. 3. All P. pectinata (n =12) generally remained in coastal waters within the region where they were initially tagged, travelling an average of 80.2 km from deployment to pop-up location. The shortest distance moved was 4.6 km and ...


Growth Of The Marine Fish-Killing Phytoflagellate, Heterosigma Akashiwo Under Emerging Coastal Regimes: Temperature, Eutrophication And Ocean Acidification, Cayla M. Bronicheski 2014 Western University

Growth Of The Marine Fish-Killing Phytoflagellate, Heterosigma Akashiwo Under Emerging Coastal Regimes: Temperature, Eutrophication And Ocean Acidification, Cayla M. Bronicheski

University of Western Ontario - Electronic Thesis and Dissertation Repository

Coastal oceans are fundamental to human economies, nutrition and recreation. Anthropogenic stressors have led to the acceleration of the nitrogen cycle, the accumulation of inorganic carbon in the earth’s atmosphere, the loss of UV-scavenging upper atmospheric ozone and the overall accumulation of deep elements from the earth’s crust to surface exposure. These changes have caused ocean acidification and eutrophication events in coastal waters and the impacts of these events on primary production and ocean biodiversity are not yet fully understood.

This study examined the effects of predicted future ocean conditions (salinity, temperature, reduced seawater pH and modified nitrogen ...


Causes And Consequences Of Broad-Scale Geographic Variation In Gulf Of Maine Rocky Intertidal Communities, Elizabeth Bryson 2014 Northeastern University

Causes And Consequences Of Broad-Scale Geographic Variation In Gulf Of Maine Rocky Intertidal Communities, Elizabeth Bryson

Biology Dissertations

A major challenge facing ecology is to better understand how large-scale processes modify local scale processes to shape the assembly and organization of ecological communities. Previous work indicates that on New England rocky intertidal shores, consumers strongly control recovery from disturbance on sheltered shores, and high recruitment and competition for space dictate recovery on wave-exposed shores. However, experimental results indicate that exposure driven consumer control is not ubiquitous throughout the Gulf of Maine, and communities in the northern Gulf exhibit limited recruitment of sessile invertebrates with extended planktonic larval stages and rapid settlement and growth of macroalgae. Based upon prevailing ...


Angler Effort And Catch Within A Spatially Complex System Of Small Lakes, Christopher J. Chizinski, Dustin R. Martin, Kevin L. Pope, Tony J. Barada, Jeffrey J. Schuckman 2014 University of Nebraska - Lincoln

Angler Effort And Catch Within A Spatially Complex System Of Small Lakes, Christopher J. Chizinski, Dustin R. Martin, Kevin L. Pope, Tony J. Barada, Jeffrey J. Schuckman

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

Spatial layout of waterbodies and waterbody size can affect a creel clerk’s ability to intercept anglers for interviews and to accurately count anglers, which will affect the accuracy and precision of estimates of effort and catch. This study aimed to quantify angling effort and catch across a spatially complex system of19 small (<100 ha) lakes, the Fremont lakes. Total (±SE) angling effort (hours) on individual lakes ranged from 0 (0) to 7,137 (305). Bank anglers utilized 18 of the 19 lakes, and their mean (±SE) trip lengths(hours) ranged from 0.80 (0.31) to 7.75 (6.75), depending on the waterbody. In contrast, boat anglers utilized 14 of the 19 lakes, and their trip lengths ranged from 1.39 (0.24) to 4.25 (0.71), depending on the waterbody. The most sought fishes, as indexed by number of lakes on which effort was exerted, were anything (17 of 19 lakes), largemouth bass Micropterus salmoides (15 of 19 lakes), and channel catfish Ictalurus punctatus (13 of 19 lakes). Bluegill Lepomis machrochirus, crappie Pomoxis spp., and largemouth bass were caught most frequently across the lakes, but catch rates varied considerably by lake. Of the1,138 parties interviewed, most parties (93%) visited ...

Developmental Mode In Opisthobranch Molluscs From The Northeast Pacific Ocean: Additional Species From Southern California And Supplemental Data, Jeffrey H. R. Goddard, Brenna Green

Bulletin of the Southern California Academy of Sciences

We document development type for 33 species of benthic opisthobranch gastropods – 15 for the first time – collected mainly from the Southern California Bight. Fourteen of the newly examined species had planktotrophic development, while the dorid nudibranch Atagema alba had capsular metamorphic development, the first example of direct development in a non-dendrodoridid nudibranch known from the northeast Pacific Ocean. For the remaining 18 species our new data are either consistent with earlier determinations of development type, or confirm previous inferences. The new data also broaden geographic coverage for some species, and for the sacoglossan Stiliger fuscovittatus and the nudibranch Melibe leonina ...

A Quantitative Evaluation Of Growth In Leptodea Fragilis Before And After The Arrival Of Zebra Mussels In Lake Erie, Elizabeth Barkett, Robert A. Krebs, Matthew T. Begley

Undergraduate Research Posters 2013

The arrival of zebra mussels in the Great Lakes in the 1980’s marked several environmental changes, most notably in freshwater mussels in the Unionidae. There are no studies of population demographics of native Great Lake species before this period of time. In this study, several recent shell collections of Leptodea fragilis, a fast-growing freshwater mussel, were made on various beaches along Lake Erie. To compare the effects of the zebra mussels on L. fragilis, we compared growth rates, determined from size and estimated age of shells, to additional collections of L. fragilis from 1941 to 1967available at the Cleveland ...


Eelgrass Distribution In The Great Bay Estuary For 2012, Frederick T. Short 2013 University of New Hampshire

Eelgrass Distribution In The Great Bay Estuary For 2012, Frederick T. Short

Piscataqua Region Estuaries Partnership

Eelgrass in the Great Bay Estuary declined in both distribution and biomass between 2011 and 2012, continuing the long-term trend of eelgrass loss. In 2012, eelgrass was once again mainly present in the Great Bay itself with limited distribution in Portsmouth Harbor and Little Bay. Eelgrass distribution in Great Bay decreased 1.5% between 2011 and 2012 with no change in biomass. In Great Bay,eelgrass distribution has declined 36% since 1996 and biomass is a quarter of what it was in the early 1990s. Nuisance macroalgae in Great Bay continued to proliferate in 2012 and to impact eelgrass by ...


Aspergillosis Of Pseudopterogorgia Americana: Increased Host Range Of Aspergillus Sydowii From The Wider Caribbean, Garriet W. Smith 2013 University of South Carolina

Aspergillosis Of Pseudopterogorgia Americana: Increased Host Range Of Aspergillus Sydowii From The Wider Caribbean, Garriet W. Smith

Journal of the South Carolina Academy of Science

Reports of gorgonian diseases have been increasing in the past few years,but, with the exception of Gorgonia spp., the etiological agents responsible are generally unknown. In the summer of 1999, populations of Pseudopterogorgia americana were observed with lesions and galls, somewhat similar to Aspergillus sydowii infections on Gorgonia ventalina, in Bermuda. Surveys of three sites were made, repeated the following two years, and compared with sites in the Bahamas. Microscopic observations of affected tissue and subsequent pure culture studies indicated the pathogen was also A. sydowii. Over half of the colonies at the Bahamas site were affected, but about ...

Zooplankton Trophic Ecology In The San Francisco Estuary During Summer As Determined By Stable Isotope Analysis, Kyla Bradylong, Steven Westbrook, Julien Moderan, Wim Kimmerer

STEM Teacher and Researcher (STAR) Program Posters

Declines in the abundance of several pelagic fish species in the upper San Francisco Estuary have prompted investigation into food web interactions within the estuary and delta (the lower Sacramento and San Joaquin Rivers). This area is characterized by low primary production and pelagic food webs much longer and reticulated than previously thought, implying low efficiency in the energy transfers from primary producers to planktivorous fish. We determined the carbon and nitrogen stable isotope (SI) composition of zooplankton samples collected monthly between June 2012 and February 2013 at eight stations along the salinity gradient. As consumers SI composition reflects that ...
