Meiofaunal distribution and abundance were studied in Marion Lake, a small, shallow (8m maximum) oligotrophic lake in southwestern British Columbia. Experimental techniques were used to investigate the influence of food and predation on meiofaunal populations, and to estimate relative carbon -flow to all components (micro-, meio-, and macrofauna) of the zoobenthic community. In two years' sampling of over 50 species of meiofaunal rotifers, nematodes, copepods, cladocerans and halacarine mites, only a few species were abundant. Three depth zones were sampled (1.0, 2.5, 4.5m) and maximum densities occurred at 2.5m. Population densities of all groups were stable over the sampling period, fluctuating less than one order of magnitude annually. In culture studies, representative meiofaunal species had longer generation times and lower reproductive rates than expected. Attempts to use laboratory results to predict field population dynamics were generally unsuccessful, but led to clarification of reproductive parameter estimates. Experiments in the laboratory and in the field suggested that meiofaunal species are not food-limited. Predation on meiofauna is not heavy but might be significant for those species whose reproduction is suppressed by adverse temperatures. Radiotracer experiments indicated that carbon flow to the zoobenthic community from sediment microflora was partitioned approximately 12% to microfauna (ciliates), 12% to meiofauna, and 76% to macrofauna, while the contributions to zoobenthic biomass were 1%, 7% and 92% respectively. In related experiments, a common harpacticoid copepod species had a high assimilation efficiency but rapidly respired and excreted recently ingested carbon. Meiofaunal organisms are apparently not an important food source for higher trophic levels in Marion Lake but may play a significant role in stimulating microfloral production by their grazing activity. / Science, Faculty of / Zoology, Department of / Graduate

Thesis advisor: Richard Kearney / This dissertation addresses and then attempts to further what could be called the “French” Phenomenological tradition and its developments of a phenomenology of eros in dialogue with—and often as a response to—older Platonic conceptions of eros. Eros, I show, had a foundational role in Plato’s ethics; becoming ethical was dependent on first having an erotic encounter with beauty. However, this connection between love and ethics has been frequently abandoned in 20th-century philosophy. I argue that this move, a side-effect of the development of a philosophy of alterity, was ultimately founded on faulty assumptions about the nature of love, as well as its connection to the good and the beautiful. For that reason, after first elucidating the concerns raised regarding an ethical eros and the reasons for the denial of love’s foundational role, I establish a definition of eros that can once again play the same role as Plato saw for it while simultaneously addressing the 20th century’s concerns about alterity and the recognition of the Other. Re-establishing this role requires arguing for three key theses: 1. Recognition of the Other is based on recognizing his or her beauty and goodness 2. Love of the Other is love of the Other as individual, not in light of some attribute 3. Love of the Other forms the basis of our entering into the ethical attitude. Combined, these theses build toward an ethical eros in two senses. First, they show that eros itself is an ethical relationship, which will be defined as an encounter with the Other structured by signification (the reasons for this definition will be made clear when I examine Levinas’ ethics). Second, the erotic encounter with one beautiful Other (which may or may not lead to a response of love) leads to the development of an ethical disposition toward all Others. In the dissertation, these theses are developed against the background of existing views about eros, in order to show their necessity, as well as to explore the reasons why they have so far been denied. Part I, “Platonic Eros,” therefore, is an in-depth reading of eros from the Platonic point of view, as seen primarily in the Symposium and Phaedrus. Part II, “Impossible Eros,” picks up on Plato’s failing to recognize the alterity of the Other and begins a critique of Plato from that point, carried out by a variety of early philosophers in the French philosophical tradition, including Jean-Paul Sartre, Jacques Lacan, and Shulamith Firestone. Part III, “Unspeakable Eros,” is a direct response to Part II, dealing primarily with Emmanuel Levinas and Jean-Luc Marion. Part IV, “Ethical Eros” is the conclusion of the dissertation, in which I argue that love can once again take on its role, assigned to it already in Plato, as the basis of ethics. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

A detailed investigation of a feature from a Phase II Archaeological Survey is undertaken and described. This feature of unusual shape and size is excavated and interpreted through archaeological and research methodologies to give a better evaluation for the Phase II investigation and a much more comprehensive study of the people who formed this feature in the mid-1800's. The artifacts recovered associated with the documented history gives a view of that time period that shows the history of a particular tract of land - site 12Ma648, Lawrence Township, Marion County, Indiana. From the government's land patent deed in 1826 to the government's reacquisition of the property in 1903, the site's occupants have left evidence of their existence and afforded a unique opportunity to study the lives of early Indiana settlers. / Department of Anthropology

In this study macro-invertebrates were sampled quantitatively in 10 lowland vegetation communities on Marion Island over a one-year period commencing in May 1996 as part of a larger investigation into the distribution, abundance and species energy use of invertebrates across an altitudinal transect on Marion Island. The data collected for this particular study were used to investigate the habitat specificity and seasonality of the macro-invertebrates, as well as the impact of alien species on the local community. As part of the latter study a watching brief for alien species was kept throughout the field year and the alien species list was updated accordingly. The quantitative data were also used to compare changes in the density and biomass of selected macro-invertebrate species between 1976/77 and 1996/97 by reworking the data on macro-invertebrates collected by Alan Burger in 1976/77 during the course of his work on the Lesser Sheathbill. In the current study it was found that the majority of the macro-invertebrate species are not particularly habitat specific. Rather, they generally prefer either moist mire habitats, or the more well-drained non-mire vegetation complexes. In addition, many of the species had pronounced peaks in abundance in a given season (winter, summer, autumn and spring peaks were recorded), although this seasonality varied between species and between habitats for a given species. Although this finding does not support previous generalizations concerning an absence of seasonality in sub-Antarctic invertebrates, it does show that sub-Antarctic invertebrates, like their Antarctic counterparts, may have extremely flexible life history strategies. Limnophyes minimus was found to be one of the most abundant alien species on the island, and reached high densities in most of the plant communities sampled, with the highest density being recorded in the Cotula plumosa biotically influenced community (annual mean of 4365 individuals.m-2 ) and the lowest in the Crassula moschata salt spray community (annual mean of 41 individuals.m-2 ). Estimates of litter ingestion indicated that L. minimus larvae are capable of consuming between 0.07 and 8.54 g(dry mass)·m-2 per year, depending on the community. In some communities this litter consumption amounted to an order of magnitude more than that consumed by Pringleophaga marioni (Lepidoptera, Tineidae). Although the larvae of this moth species are thought to represent the bottleneck to nutrient recycling on the island, this study showed that midge larvae may also contribute substantially to this process. As a consequence, the considerable changes that have been predicted to occur in Marion Island's terrestrial ecosystem as a consequence of enhanced predation by mice on P. marioni larvae, may be retarded or obscured by the contribution of the midge larvae to nutrient cycling. Hence, it is suggested that greater attention be given to the small and inconspicuous elements of the alien sub-Antarctic faunas because such species may have profound consequences for ecosystem functioning on these islands. The likely impact of alien species on the terrestrial macro-invertebrates, and the communities they belong to, was further highlighted by the dramatic decline in the biomasses of the macro-invertebrates between 1976/77 and 1996/97. Significant declines in biomass of between 83-97% were found for Lepidoptera larvae (mostly Pringleophaga marioni) and for weevils, the major prey species of the introduced house mouse between 1976/77 and 1996/97, although non-prey species appear to have shown either no changes (the indigenous snail Notodicus hookeri) or increases in abundance (the introduced slug Deroceras caruanae). However, differences in sampling strategies adopted by these two studies and others investigating macro-invertebrate abundances mean that the current results may well be underestimates of change, while other studies must be interpreted with considerable caution. Nonetheless, the current findings and those of authors suggest that mice may be having pronounced impacts on the terrestrial ecosystem at Marion Island. In sum, the findings of this thesis indicate that considerably more attention must be given to well-planned collaborative work to address critically important management questions, identified by the Prince Edward Island Management Committee, and that considerable care must be taken to prevent the further introduction of alien species to sub-Antarctic islands.
