An Examination Of Predatory Pressures On Piping Plovers Nesting At Breezy Point, New York, Brook Lauro, John Tanacredi Ph.D.
An Examination Of Predatory Pressures On Piping Plovers Nesting At Breezy Point, New York, Brook Lauro, John Tanacredi Ph.D.
Faculty Works: CERCOM
This study examines predatory threats to Piping Plovers (Charadrius melodus) nesting at Breezy Point, Gateway National Recreation Area, New York. Several methods used include: 1) an evaluation of reproductive success data with documentation of predation to eggs and chicks, 2) predator surveys, and 3) an artificial nest study. The range of breeding pairs nesting from 1988-1996 was 11-19, with an average of 15.8 (SE ± 0.79) pairs/season. The average number of eggs hatched and chicks fledged per year for pairs was 2.2 ± 0.23 and 0.8 ± 0.16 respectively. Reasons for egg losses often went undetected (68%) but …
Modeling The Role Of No-Take Marine Reserves In Fisheries Management, Deidre F. Gilbert
Modeling The Role Of No-Take Marine Reserves In Fisheries Management, Deidre F. Gilbert
Electronic Theses and Dissertations
In recent years there has been increasing interest in the potential of no-take marine reserves to benefit fisheries management. Scientific reviews have shown that reserves often lead to substantial increases in the density, biomass, size and diversity of marine fishes inside their boundaries. However, little empirical work has been done to determine the effect of reserves on the fisheries outside their boundaries, such as potential changes in yield, size of fleet, or variability in catch. In order to explore the interaction between the biological growth and dispersion processes of the harvested stock and the changing economic incentives of harvesters created …
A Pilot Study To Test Ventless Traps As A Means To Quantify Populations Of The American Lobster (Homarus Americanus), Carin Louise Poeschel
A Pilot Study To Test Ventless Traps As A Means To Quantify Populations Of The American Lobster (Homarus Americanus), Carin Louise Poeschel
Electronic Theses and Dissertations
The American lobster, Homarus americanus, is Maine's most valuable marine fishery. The state of Maine has an economic interest in the protection of this resource. The health of this industry depends on effective management for sustainability. However, there is little quantitative information on American lobsters less than harvestable size. A study was conducted to evaluate the utility of traps modified to catch sublegal lobsters. With the aid of fishernlen fiom six of the eight Maine coastal counties over a four-month time period (July through October, 2000), data were recorded to compare catch rates in experimental traps with no escape vents …
Ecology Of The Missouri River. Progress Report, Dingell-Johnson Project F-75-R-19, Supplement 1- Missouri River Creel Survey, Camp Creek To Kansas State Line, 31 March Through 12 October 2001, Gerald Mestl
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This report describes Missouri River activities and results related to a channelized Missouri River creel survey conducted from 31 March through 12 October 2001. This is the second of a planned annual creel survey to be conducted on alternating sections of the channelized Missouri River to measure changes in recreational fishing activity, especially those changes due to large scale habitat restoration efforts. Future reports will contain additional analyses of these data. Anglers spent over 22,000 hours fishing the Missouri River from Camp Creek (rkm 883.5) to the Kansas state line (rkm 790.2) during the survey period. Effort peaked during the …
Marine Protected Areas In The Gulf Of Maine: Policy For A Common Resource, Carolyn F. Skinder
Marine Protected Areas In The Gulf Of Maine: Policy For A Common Resource, Carolyn F. Skinder
Electronic Theses and Dissertations
In the wake of 25 years of unsuccessful single-fisheries management in the Gulf of Maine, there has been growing support for reform. Ecosystem management has been proposed as one alternative, but the information needed to manage whole ecosystems is greatly lacking. Implementing fully-protected marine protected areas (MPAs) is one way to preserve habitat while at the same time acquiring data for future ecosystem management. Under the current institutional arrangement in the Gulf, engineering agreement for MPAs is difficult due to the differing goals of varied user groups. The situation is reflective of a common property resource problem in that there …
Captive Double-Crested Cormorant Phalacrocorax Auritus Predation On Channel Catfish Ictalurus Punctatus Fingerlings And Its Influence On Single-Batch Cropping Production, Brian S. Dorr
Brian S Dorr
Abstract.-We studied the effect of captive double-crested cormorant Phalacrocorax auritus predation on channel catfish Ictalurus punctatus inventories from research ponds with and without alternative prey during the years 1998-2000. In 1998, predation by two groups of captive cormorants on ponds without alternative prey produced inventory reductions relative to a control pond that were equivalent to 10.2 (516 g) and I 0.5 (608 g) catfish/bird per d. In 1999 and 2000 individual cormorants foraging on 0.02-ha pond halves for I 0 d (500 cormorant d/ha) stocked with both catfish and golden shiners Notemigonus crysoleucas produced inventory reductions at harvest (7.5 mo …

Comparisons In Morphology, Reproductive Status, And Feeding Ecology Of Plethodon Cinereus At High And Low Elevations In West Virginia, Mizuki Takahashi
Comparisons In Morphology, Reproductive Status, And Feeding Ecology Of Plethodon Cinereus At High And Low Elevations In West Virginia, Mizuki Takahashi
Theses, Dissertations and Capstones
To develop effects of elevation on morphological features, reproductive status, and feeding ecology of Plethodon cinereus in West Virginia, overall comparisons between high (>4000 ft) and low (<1260 ft) elevation populations were made. Adult P. cinereus from high elevations were smaller in SVL (female: p=0.003, male: p<0.001), but stored larger amounts of fat (female: p=0.041, male: p=0.006) in their tails than fromlow elevations. Larger amounts of tail fat could be an adaptation to harsh environments at high elevations. It was determined that in West Virginia, where as females at low elevations oviposit annually, females at high elevations oviposit biennially. Stomach content analysis revealed that salamanders at high elevations were confronted by food shortage. Because of less prey availability and longer winters at high elevations, salamanders at high elevations attained the smaller body size than at low elevations and could not obtain sufficient energy in 1 year to yolk a clutch.
Effects Of Developmental Activities On Streamside Salamander Communities In Boone County, West Virginia, Mindy S. Hamilton
Effects Of Developmental Activities On Streamside Salamander Communities In Boone County, West Virginia, Mindy S. Hamilton
Theses, Dissertations and Capstones
A study was conducted from May 1998 through June 1999 in three streams associated with mountaintop mining and valley fills in Boone County, West Virginia. Streamside salamander communities were monitored in these streams, as well as in two relatively undisturbed reference streams in the region, using refugia bags, rock-on-rock methodology, and day surveys. The relative abundance of salamanders was compared between the streams in order to detect effects of the associated valley fills to downstream biota. Relative abundance was lower in two of three streams associated with valley fills as compared to the reference streams. However, there was no significant …
Morphological Variation Of Allocreadium Lobatum (Digenea: Allocreadiidae) In The Creek Chub, Semotilus Atromaculatus (Osteichthyes: Cyprinidae), In Nebraska, Usa, Monte S. Willis
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Allocreadium lobatum Wallin 1909, a parasite of fresh-water fish, was originally described as having distinct lobate testes, and subsequent descriptions have left this original description unchanged. The present study quantifies the observation of distinctly non-lobate testes that could be categorized as round or asymmetrical in addition to the previously described lobate testes. Six hundred thirty-six A. lobatum were collected from 228 Semotilus atromaculatus over a 9 month period. Overall, 21.3%, 61.6%, and 16% were found to be round, asymmetrical, and lobate testes respectively (N = 1,071). Analysis of testis morphology found the increasing presence of lobate testis as …
