Effects Of Copper On Gill Structure And Physiology In Carcinus Maenas, Dagmar Karina Hebel

School of Biological and Marine Sciences Theses

The effects of sublethal copper exposure at three levels of biological organisation were studied in the common shore crab Carcinus maenas (L.) (Crustacea, Decapoda). The three levels included the ultrastructure of respiratory and osmoregulatory gill tissues; ventilatory physiology (scaphognathite activity); and tissue metallothionein levels. Respiratory gill epithelia were more sensitive to sublethal copper exposure than osmoregulatory gill tissues. The cellular damage observed included severe epithelial necrosis and vacuolation, hyperplasia and haemocyte infiltration. In the respiratory gills, these changes were first present following exposure to 100 µg Cu Lˉ¹ At 500 µg Cu Lˉ¹, there was complete degeneration of the epithelia. …

Environmental Variables, Including Pollutants, Affecting Living Benthonic Foraminiferida, Catherine Jane Manley

School of Biological and Marine Sciences Theses

Studies of living benthonic foraminiferal assemblages carried out by marine biologists are comparatively rare. This study of the changes in foraminiferal assemblages from three subtidal sites near Plymouth, U.K., has been carried out with the intention of determining the importance of various abiotic and biotic variables to the foraminiferal communities studied using statistical correlation. Temperature and salinity at depth and particle size characteristics together with organic content, bacterial abundance and type, and other meiofauna present were assessed monthly with samples taken for foraminiferal content, and for seasonal diatom analysis. Deformed specimens were very rare in the examined samples of natural …

The Innervation And Physiology Of The Cardiac Tissue In Squid, Maria Pernilla Odblom

School of Biological and Marine Sciences Theses

Cephalopods have one of the most sophisticated cardiovascular systems among the invertebrates; they have an enclosed high pressure blood system, characterised by a double circulation, with one main systemic heart and two gill hearts. The cephalopod cardiac tissues are basically myogenic, but there is evidence for both nervous and hormonal regulation of most parts of the cardiovascular system, although the details of the control systems remain unknown. This study investigated the physiology and innervation of the cardiac tissues of the squid Alloteuthis subulata, Loligo forbesii and L vulgaris. Histological staining techniques established that the cardiac organs in squid are innervated …

The Influence Of Vitamin E On The Immune System Of The Rainbow Trout (Oncorhynchus Mykiss), Janet Roper

School of Biological and Marine Sciences Theses

This study took the form of three nutritional trials each examining the effects of vitamin E on various physiological, haematological and immunological functions of the rainbow trout. The preliminary study investigated the effect of feeding three experimental diets with different levels of alpha-tocopherol supplementation (0, 100 and 800 mg kgˉ¹ diet), on growth, health and various factors of the non-specific immune response. Liver alpha-tocopherol levels reflected the dietary intake of the vitamin. The fish fed the diet deficient in alpha-tocopherol showed reduced growth and increased mortality They had pale enlarged livers, their hepatosomatic indices and erythrocyte fragility was significantly higher …

The Unit Letter : A Strategy For Reconciling Explicit Instruction And Whole Language, Lucy Butin Ashby

Graduate Research Papers

Though differences between whole language and explicit instruction theories and research may seem irreconcilable, a growing body of research advocates an integration of the two. Combining the meaning-filled and student-empowering environment of whole language with needs-based explicit instruction is the solution most highly recommended. The unit letter activity is a teaching strategy for elementary-aged students which blends explicit instruction and whole language approaches. The activity involves student interaction with a thematic-related letter. The activity's purposes are two-fold : to convey information related to a theme chosen by the students, and to provide an authentic context for learning and practicing reading …

Why It Is Important To Keep Recess In Schools, Mary Lou Mcgee Cushing

Graduate Research Papers

Recess is a common part of most elementary school schedules yet its benefits are often not clearly articulated. As a result recess may be thought to be expendable from school curricula as school districts adjust already full schedules in an attempt to accommodate every necessary component.

This research review explores the relationship of recess to school schedules, time allotments, activities commonly observed at recess, and developmental (social, cognitive, and psychomotor) aspects of recess in schools. Also addressed are common criticisms of recess in schools.

Backpacking To Reading Success : Parents And Teachers Working Together To Promote Literacy Development, Anita M. Ott

Graduate Research Papers

Literature has stressed the importance of reading at home to guide achievement in reading (Paul, 1996, Nichols, 1991, Anderson, Wilson & Fielding, 1988, Henderson, 1988, and Hewison and Tizard, 1980). However the pace of society in the United States today has made it difficult for families to make time for reading at home. In addition some families do not know the importance of reading at home, or have not made reading a priority.

This project provides a suggested home reading program to foster literacy development in elementary-aged students. Four major components are addressed: a) identifying a continuum of literacy development, …

Law And Fancy, Robin West

Georgetown Law Faculty Publications and Other Works

Martha Nussbaum's graceful book Poetic Justice is an elegant brief for the importance of our capacity for imaginative "fancy" to our moral and legal lives. Imaginative fancy, Nussbaum argues, allows us to know the internal substance and quality of the lives of others. It allows us to come to appreciate, to understand, to share, and ultimately to resist others' suffering. It is, in short, the means by which we come to care about the fate and happiness of others. It is a part, but not the whole, of our capacity to transcend a narcissistic and infantile egoism. It is therefore …

Individualism And Evolutionary Psychology (Or: In Defense Of 'Narrow' Functions), David J. Buller

Faculty Articles, Papers, and Other Scholarship

Millikan (1993) and Wilson (1994) argue, for different reasons, that the essential reference to the environment in adaptationist explanations of behavior makes (psychological) individualism inconsistent with evolutionary psychology. I show that their arguments are based on misinterpretationso f the role of referencet o the environmenti n such explanations. By exploring these misinterpretationsI, develop an account of explanation in evolutionary psychology that is fully consistent with individualism. This does not, however, constitute a full-fledged defense of individualism, since evolutionary psychology is only one explanatory paradigm among many in psychology.
