The Other Side Of Silence: Rachel Carson’S Views Of Animals, Marc Bekoff, Jan Nystrom

Animal Welfare Collection

The publication of Rachel Carson’s Silent Spring in 1962 is widely regarded as one of the major events that launched the modern environmental movement. Silent Spring is a compelling blend of stories, natural history, human values, and biological facts. In this essay we consider Carson’s attitude toward animals in Silent Spring and in other texts. Despite the facts that she was raised to love Nature and animals, little direct attention has been given to Carson’s views about our moral responsibilities to, and the moral standing of animals. Carson favored responsible stewardship, was more of an animal welfarist and environmentalist/conservation biologist …

Lexen: Role Of Atmospheric Trace Gases In Microbial Colonization And Succession On Recent Lava Flows, Gary M. King

University of Maine Office of Research Administration: Grant Reports

Drs. Gary M. King of the University of Maine and Klaus Nusslein of the University of Massachusetts-Amherst have been awarded a grant from the NSF Life in Extreme Environment (LExEn) program to determine the role of atmospheric trace gases in microbial colonization and succession on recent lava flows. Volcanic activity has played an important role in the development of terrestrial ecosystems for much of Earth's history, and continues to shape terrestrial environments at present. Deposition of lava and tephra result in surfaces that over time support complex, highly productive biological communities. However, young or recently extruded lavas represent extreme environments …

Predators In Natural Fragments: Foraging Ecology Of Wolves In British Columbia’S Central And North Coast Archipelago, C. T. Darimont, M. H. H. Price, N. N. Winchester, J. Gordon-Walker, P. C. Paquet

Biogeography and Ecological Opportunity Collection

Aim Predator–prey dynamics in fragmented areas may be influenced by spatial features of the landscape. Although little is known about these processes, an increasingly fragmented planet underscores the urgency to predict its consequences. Accordingly, our aim was to examine foraging behaviour of an apex mammalian predator, the wolf (Canis lupus), in an archipelago environment.

Location Mainland and adjacent archipelago of British Columbia, Canada; a largely pristine and naturally fragmented landscape with islands of variable size and isolation.

Methods We sampled 30 mainland watersheds and 29 islands for wolf faeces in summers 2000 and 2001 and identified prey remains. We examined …

Apparent Sibling Rivalry In The Freshwater Clam Sphaerium Striatinum, Mark Beekey, Ronald H. Karlson

Biology Faculty Publications

In Sphaerium striatinum, a freshwater brooding bivalve, up to 97.5% of offspring that adults initially produce fail to reach independence. Marsupial sacs, specialized extensions of gill filaments that act as nurseries, initially contain multiple offspring in various sizes and stages of development. However, by the time offspring reach later stages of development, marsupial sacs typically contain only one offspring. Brood mortality is hypothesized to be the result of competition among embryos for nutrients and/or space. Sphaeriid eggs do not contain enough yolk for offspring to complete development. Adults supply additional nutrients required to reach independence. Brood capacity is limited by …

A Trophic Model For Kuosheng Bay In Northern Taiwan, Hsing-Juh Lin, Kwang-Tsao Shao, Jiang-Shiou Hwang, Wen-Tseng Lo, I-Jiunn Cheng, Lih-Huwa Lee

Journal of Marine Science and Technology

Using the Ecopath with Ecosim software system, a mass-balanced trophic model of Kuosheng Bay, where the Second Nuclear Power Plant is sited on the coast, was constructed. This model comprised 17 compartments, ranging from a trophic level of 1.00 for primary producers and detritus to 3.97 for piscivorous fish. The geometric mean of the trophic transfer efficiencies was 6.5%. The lower efficiencies were attributable to high flows to detritus, suggesting that the food web was more dependent on detritus than on primary producers to generate total system throughput. The total system throughput, system production, and system biomass were comparable to …

Effects Of Nuclear Power Plant Thermal Effluent On Marine Sessile Invertebrate Communities In Southern Taiwan, Yalan Chou, Ta-Yu Lin, Chen-Tung Arthur Chen, Li-Lian Liu

Journal of Marine Science and Technology

The present study aimed at determining the impact of cooling water discharge from a Nuclear Power Plant in Kenting, Taiwan on the recruitment patterns of marine invertebrates. Field experiments were conducted over a six-year period in the vicinity of the power plant, with six control sites, five at influent areas, one at reference site, and three experimental sites at effluent areas. In general, among the monitoring sites, polychaetes and bryozoans were the most abundant organisms, and their recruitment on settlement plates was always higher in influent than in effluent areas. Partially as a result of a 5-week accidental shutdown of …

The Coastal Currents Offshore The Nuclear Power Plants At Northern Taiwan, Jian-Hwa Hu

Journal of Marine Science and Technology

Coastal tidal currents play an important role to disperse the warm waters outlet from cooling system of a nuclear power plant (NPP). The modern technique of ship-board acoustic Doppler current profiler (SB-ADCP) was intensively applied to scan the current fields around the three NPPs at northern Taiwan. Sophisticated data processing provides time series of synoptic flow charts of vectors in grids associated with streamlines, allowing the visualization of how the bay like coastline input its boundary layer effect to the current field. The generation of cyclonic or anti-cyclonic vortices inside the bay in flood or ebb tide and their migration …

Chaetoceros compressus, Pseudo-nitzschia delicatissima, Skeletonema costatum, Thalassionema nitzschioides, and Lauderia annulata were the top five dominant species. Together they comprised 75% of the total phytoplankton cells. The species number and abundance of phytoplankton showed distinct seasonal, annual, and spatial changes, higher abundance in 2002 than 2001 and highest in August in both years and lowest in March in 2001 and …

Effect Of Thermal Discharges On The Fish Assemblages Of A Nuclear Power Plant In Northern Taiwan, Ching-Yi Chen, Kwang-Tsao Shao, Yueh-Yuan Tu

Journal of Marine Science and Technology

The purpose of this paper is to study whether the thermal plume can affect the fish assemblages in the waters around the outlet area of the Second Nuclear Power Plant located at Kuosheng, a coastline between Yehliu and Chinshan village, northern coast of Taiwan. Both experimental and control stations of underwater census for reef fishes and of drift net sampling for pelagic or demersal fishes above sandy bottom were monitored four times per year from March 2001 to September 2004. The results show that no significant dif-ferences were found between the fish assemblages of the thermal waters and normal ambient …

Marine Environmental Radioactivity Near Nuclear Power Plants In Northern Taiwan, Chih-An Huh, Chih-Chieh Su, Yueh-Yuan Tu, Kwang-Tsao Shao, Ching-Yi Chen, I-Jiunn Cheng

Journal of Marine Science and Technology

The levels and composition of environmental radioactivity at the outlets of nuclear power plants and nearby coastal environs in northern Taiwan have been investigated by gamma spectrometric analysis of seawater, algae, fish and sediment samples collected systematically in the past four years. The results show that anthropogenic radionuclides contribute very little to the total radioactivities in all types of samples. Samples from the outlet of the Second Nuclear Power Plant are more enriched in artificial nuclides, with average algae samples containing ~4 Bq/kg of 137Cs + 54Mn + 60Co (or 3.6% of the total activity) and average sediment samples containing …

Journal of Marine Science and Technology

The nuclear power plants are very important and cheap electric power source for Taiwan. However, the Nuclear Power Plant I and II (NPP I and II) are located in the northern Taiwan where the most populations inhabit. Therefore, the impact of operation of nuclear power plants on the surrounding environment, particularly in the surrounding waters, has drawn great attention to the public of Taiwan. Here we reported the first analyses on a three-year period of monitoring copepod assemblages in the adjacent waters to the NPP I and II. The copepod assemblages in the vicinity waters of NPP I and II …

Nearshore Macrobenthic Communities Off Two Nuclear Power Plants In Northern Taiwan, I-Jiunn Cheng, Pou-Chung Ko, Shin-I Hu, Chien-Peng Hu, Trip-Ping Wei

Journal of Marine Science and Technology

The nearshore macrobenthic communities outside the Nuclear Power Plants I and II were monitored on a seasonal basis from winter, 2000 to summer, 2004. The animal and sediment were sampled by scuba diving. The macrobenthic assemblages, sediment characteristics and total organic content were analyzed. The macrobenthos assemblages in terms of species richness, density and biomass was determined. The mean grain size and sorting (i.e. inclusive graphic standard deviation) of sediment were also determined. The small-sized annelids and crustaceans were the dominant macrobenthos. A total of 96 species of macrobenthos was found in the sediment near the Nuclear Power Plant I. …

Temporal Changes In Fish Assemblage From The Impingement Data At The Second Nuclear Power Plant,Northern Taiwan, Yun-Chih Liao, Li-Shu Chen, Kwang-Tsao Shao, Yueh-Yuan Tu

Journal of Marine Science and Technology

The main purposes of this study are to find out the temporal fluctuation of marine fish community based on impingement data collected at the Second Nuclear Power Plant in recent years (September 2000 to May 2004), and to compare the recent fish community structure data to that of an earlier period, around 14 years ago (July 1987 to April 1990). Comparison of the data collected recently to that collected 14 years ago showed that there were no yearly or monthly differences. However, the community structures reflected by clustering dendrograms or MDS ordination plots were quite different between earlier and recent …

Physical Properties Of Thermal Plumes From A Nuclear Power Plant In The Southernmost Taiwan, Sen Jan, Chen-Tung Arthur Chen, Yueh-Yuan Tu, Hsien-Shiow Tsai

Journal of Marine Science and Technology

Circulation and hydrographic variations in the inner shelf of a semi-enclosed bay adjacent to a nuclear power plant of the southernmost Taiwan were analyzed using intensive observation data from 2003-2004. The dominant tide in the bay is a mixture of diurnal and semidiurnal components. Currents are dominated by tidal forcing which flows southwestward during flood and northeastward during ebb. The amplitudes of tidal currents range from 0.2 to 0.4 m/s. A persistent southwestward subtidal flow is present with a mean velocity of 0.15 m/s. The upwelled cold deep water in the central bay can intrude to the inner reach near …

Upwelling And Degree Of Nutrient Consumption In Nanwan Bay, Southern Taiwan, Chen-Tung Arthur Chen, Bing-Jye Wang, Li-Yu Hsing

Journal of Marine Science and Technology

The newly proposed Degree of Nutrient Consumption (DNC) of upwelled waters was used to evaluate the upwelling process in Nanwan Bay off the southern tip of Taiwan. DNC values were found to be low in subsurface waters or in newly upwelled waters. In general, a low DNC value was detected alongside other traditionally used upwelling indicators such as lower temperature, pH and % oxygen saturation but higher salinity, nutrients and chlorophyll a. On the other hand, the DNC value could be several times higher in aged upwelled water found in the surface layer.

Strong Interactions Between Juvenile Caribbean Spiny Lobster (Panulirus Argus) And Caribbean Reef Octopus (Octopus Briareus) In The Florida Keys, Jennifer Anne Lear

Biological Sciences Theses & Dissertations

Coexisting species may simultaneously compete for resources and interact as predator and prey, creating a strong interaction that can alter the structure of animal communities. This type of interaction potentially occurs between juvenile Caribbean spiny lobster (Panulirus argus) and Caribbean reef octopus (Octopus briareus) within hard-bottom habitats in the Florida Keys, FL (USA), where octopuses may consume juvenile lobsters and also compete with them for limited crevice shelters. I conducted a series of field and mesocosm studies to investigate the nature of octopus-lobster interactions and their implications for the structure of their populations in the wild. …

Zebra Mussels Affect Benthic Predator Foraging Success, Mark Beekey, D. J. Mccabe, I. E. Marsden

Biology Faculty Publications

The introduction of zebra mussels (Dreissena spp.) to North America has resulted in dramatic changes to the complexity of benthic habitats. Changes in habitat complexity may have profound effects on predator-prey interactions in aquatic communities. Increased habitat complexity may affect prey and predator dynamics by reducing encounter rates and foraging success. Zebra mussels form thick contiguous colonies on both hard and soft substrates. While the colonization of substrata by zebra mussels has generally resulted in an increase in both the abundance and diversity of benthic invertebrate communities, it is not well known how these changes affect the foraging efficiencies of …

Historical Biogeography Of The Woodchuck (Marmota Monax Bunkeri) In Nebraska And Northern Kansas, Zachary P. Roehrs, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Discusses the historical biogeography of the Woodchuck (Marmota monax bunkeri) in Nebraska and northern Kansas.

First paragraph:

Jones et al. described the western limit of Marmota monax in the United States as the eastern edge of the northern Great Plains in Oklahoma, Kansas, Nebraska, and the Dakotas. Mengel introduced the idea of the Great Plains grasslands as a barrier to contact between birds of eastern and western North American forests. In his studies of bird biogeography on the Platte River, Knopf reported that this barrier has eroded with development of riparian forests along river courses of the Great …

Effects Of Management Practicesmon Grassland Birds: Brewer’S Sparrow, Brett Walker

Effects of Management Practices on Grassland Birds

Information on the habitat requirements and effects of habitat management on grassland birds were summarized from information in more than 5,500 published and unpublished papers. A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although birds frequently are observed outside the breeding range indicated, the maps are intended to show areas where managers might concentrate their attention. It may be ineffectual to manage habitat at a site for a species that rarely occurs in an area. The species account begins with a brief capsule statement, which …

A New Species Of Callulina (Anura: Microhylidae) From The West Usambara Mountains, Tanzania, Rafael O. De Sá, Simon P. Loader, Alan Channing

Biology Faculty Publications

The description of the species Callulina kreffti was based on specimens collected in the East Usambara Mountains of Tanzania. Successive collecting has shown this species to be widely distributed through the Eastern Arc Mountains. Advertisement calls from populations in the type locality of Callulina kreffti were compared with calls from populations in the West Usambara Mountains. Analysis of the calls suggested that these two populations of Callulina represent two separate taxa. Subsequent morphological and molecular investigations indicated that these two populations are distinct. Herein, we describe a new Callulina species on the basis of call, morphology and molecular sequences.

A New Toad (Anura: Bufonidae) From Uruguay, Raúl Maneyro, Diego Arrieta, Rafael O. De Sá

Biology Faculty Publications

A new species of toad is described from small streams in the hills of Cuchilla de Haedo and Cuchilla Grande in northeastern Uruguay. Specimens of the new species were previously mistaken for Bufo arenarum; they differ from B.arenarum by having elongated parotoid glands and reddish-brown parotoid and cephalic crests. A discriminant analysis resulted in three groups corresponding to B. arenarum, Bufo rufus, and the specimens herein described as a new species.
