Community Ecology And Genetics Of Macroinvertebrates In Permanent Macaronesian Streams., Lucy Claire Kelly Jan 1996

Community Ecology And Genetics Of Macroinvertebrates In Permanent Macaronesian Streams., Lucy Claire Kelly

School of Biological and Marine Sciences Theses

Extensive community-based sampling and single-species genetic analysis were used to study factors driving stream invertebrate community assembly on islands. Macroinvertebrates and physicochemistry were surveyed in forty-two streams on La Palma, La Gomera, Tenerife and Madeira (Macaronesia). Island faunal relationships and the role of the stream and catchment environment in determining community composition were investigated with multivariate analyses; assemblage nestedness and species richness, occupancy and abundance were also examined. The relationship between genetic differentiation and range size was tested using allozyme variation in selected species. Island species pools differed in community composition and species richness (total, and endemic), broadly as predicted …

Ecology And Community Relationships Of The River Cooter, Pseudemys Concinna In A Southern Illinois Backwater, Michael J. Dreslik Jan 1996

Ecology And Community Relationships Of The River Cooter, Pseudemys Concinna In A Southern Illinois Backwater, Michael J. Dreslik

Masters Theses

In Illinois the River cooter, Pseudemys concinna, is an enigmatic endangered species. Even throughout its range, ecological studies on the River cooter are rare. During 1994 and 1995 I quantified the: growth rates and trends, population size and structure and dietary habits of a population from floodplain lake in Gallatin county, Illinois. Population estimation (Schnabel method) predicted 136 individuals at a density of 4.6 turtles/ha with a biomass of 3.6 Kg/ha. The sex ratio is slightly male biased (1:1.14). From back-calculated growth data, the von Bertalanffy growth model (Fabens' method) estimates males with a higher growth rate (k) and …

A Guide For Extending Nature Lessons At The Yakima Arboretum, Kathleen D. Brown Jan 1996

A Guide For Extending Nature Lessons At The Yakima Arboretum, Kathleen D. Brown

All Graduate Projects

The importance of providing a hands on natural environment curriculum was examined. Sources from 1938-1996 were found supporting the importance of such a curriculum. A search was conducted on the availability of a natural habitat curriculum that used a local resource. The search discovered the Yakima Arboretum had seven areas of interest along with a packet of brief lesson suggestions. These lessons were extended to include classroom activities that would provide students with background knowledge prior to a field trip to the Arboretum.

A Recent Colonization Of Dolichopoda Cave Crickets In The Poscola Cave (Orthoptera, Rhaphidophoridae), Camilla Bernardini, Claudio Di Russo, Mauro Rampini, Donatella Cersaroni, Valerio Sbordoni Jan 1996

A Recent Colonization Of Dolichopoda Cave Crickets In The Poscola Cave (Orthoptera, Rhaphidophoridae), Camilla Bernardini, Claudio Di Russo, Mauro Rampini, Donatella Cersaroni, Valerio Sbordoni

International Journal of Speleology

We report a series of investigations carried out on a Dolichopoda population recently discovered in the Poscola cave and in some small caves nearby (Lessini Mountains, Vicenza). This population is located north of Po river, outside the present known geographic range of this genus in Italy. Morphology of the epiphallus corroborated by chromosome and allozyme analysis indicated that this population belongs to D. laetitiae. Study of the genetic structure of population in the Poscola area revealed high gene flow levels between Poscola and the other minor caves, suggesting the occurrence of a single expanding population. This finding as well …

An Examination Of The Effects Of The Mother's Education And Household Exposure To Disease On Childhood Diarrheal Morbidity In Sudan., Dawood Hussein Sultan Jan 1996

An Examination Of The Effects Of The Mother's Education And Household Exposure To Disease On Childhood Diarrheal Morbidity In Sudan., Dawood Hussein Sultan

LSU Historical Dissertations and Theses

This dissertation examines the effect of increases in the mother's level of education on the likelihood of diarrheal morbidity among Sudanese children aged 6 to 23 months. Maximum likelihood logistic regression models are used in the analysis. The logit estimates obtained from these models revealed that children of mothers who are illiterate run on average more than 10 times the risk of diarrhea as that run by children to mothers with a senior secondary or higher education. Slight increases in the mother's education, as indicated by an incomplete primary school education, reduce the likelihood of diarrhea by more than 50%. …

The Conservation And Ecology Of The Heath Lobelia, Lobelia Urens L., Janet Mary Dinsdale Jan 1996

The Conservation And Ecology Of The Heath Lobelia, Lobelia Urens L., Janet Mary Dinsdale

School of Biological and Marine Sciences Theses

This programme of research examines the ecology of the threatened perennial Lobelia urens L. (the heath lobelia) which reaches the northern limit of its distribution in the southern coastal counties of England. A survey of the historical evidence of the distribution of the species in England is presented. Restricted to such a small area, L. urens has always been rare in Britain. The six remaining populations were surveyed to describe the phytosociology of communities containing L. urens and the variability of the environmental factors controlling its distribution. L. urens is shown to be a member of rough grass-heath communities dominated …

A Functional Group Approach To Detecting Shifts In Macroalgal Communities Along A Disturbance Gradient, J. C. Phillips Jan 1996

A Functional Group Approach To Detecting Shifts In Macroalgal Communities Along A Disturbance Gradient, J. C. Phillips

Theses : Honours

A recently proposed hypothesis argued that morphologically and functionally similar macroalgae could be grouped to study the structure of macroalgal communities. It was argued that these functional groups can be used to predict changes to community composition that result from disturbance. This study examined whether the functional group model held in detecting changes in macroalgal community structure within one bioregion, by applying it to a habitat exposed to different levels of physical disturbance associated with wave exposure. Results obtained using a functional group approach were compared to those obtained using a species level approach. Three parallel reef lines in Marmion …

Avian Habitat Use In Southern Nevada Riparian Areas With Varying Amounts Of Tamarix Ramosissima, Sandra Lou Haigh Jan 1996

Avian Habitat Use In Southern Nevada Riparian Areas With Varying Amounts Of Tamarix Ramosissima, Sandra Lou Haigh

UNLV Retrospective Theses & Dissertations

Avian species richness, species diversity, and density were measured and compared over a 21 month period on six riparian sites in Lake Mead National Recreation Area (LMNRA), southern Nevada. Sites consisted of two lake shore areas with almost pure stands of Tamarix ramosissima and four stream side areas, two with mixed Tamarix and native vegetation and two with only native vegetation. Overall mean avian species richness, diversity, and density were lowest on lake shore sites, intermediate on mixed stream sites and highest on stream sites with native vegetation. Differences in these values were significant between lake shore and stream sites …

Parental Investment In The Red-Eared Slider Turtle, Trachemys Scripta, Michael D. Marlen Jan 1996

Parental Investment In The Red-Eared Slider Turtle, Trachemys Scripta, Michael D. Marlen

Masters Theses

This study was conducted to determine egg and hatchling components of the red-eared slider (Trachemys scripta). In addition, energy components transferred from egg to hatchling were used to determine the level of parental investment in embryogenesis and hatchling care. Eggs of the red-eared slider, collected from central Illinois ponds, were obtained by inducing gravid females to lay by an injection of oxytocin. Egg and hatchling lipids were extracted with petroleum ether while egg and hatchling protein content was determined using the micro-Kjeldahl procedure. Eggs averaged 70.7% water by mass, and dry mass of whole eggs and egg yolks averaged 2.4g …

Timing Of Metamorphosis In A Freshwater Crustacean: Comparison With Anuran Models, Saran Twombly Jan 1996

Timing Of Metamorphosis In A Freshwater Crustacean: Comparison With Anuran Models, Saran Twombly

Biological Sciences Faculty Publications

Many crustaceans have complex life cycles characterized by a metamorphosis, yet variation in metamorphic traits, and the causes and consequences of this variation, have rarely been examined. Food concentrations were changed during specific larval stages of the freshwater copepod Mesocyclops edax Forbes (Copepoda: Cyclopoida) to examine whether age and size at metamorphosis remain flexible or become fixed during the larval period. Results were compared to predictions of both flexible (the Wilbur—Collins model) and fixed (Leips—Travis model) rate models for the timing of amphibian metamorphosis. Age and size at metamorphosis were variable in all treatments, and age was always more variable …

The Spatial Characterisation Of Transitional Areas Between Plant Communities: A Case Study From Upland Britain, Wendy Jane Gill Jan 1996

The Spatial Characterisation Of Transitional Areas Between Plant Communities: A Case Study From Upland Britain, Wendy Jane Gill

School of Geography, Earth and Environmental Sciences Theses

The concept of the ecotone was formalised by Clements (1 905) as a boundary zone between plant communities. Little research exists on the ecological importance or the geographical variability of these zones. Two types of boundaries are acknowledged: the ecotone and the ecocline. The ecotone is a sharp boundary; the ecocline a gradual boundary. The term 'transitional area' is proposed here to more accurately describe these areas as this research demonstrates that a complex continuum exists between the two end points. Additionally, mosaics often complicate the nature of the transition and may form a boundary type in their own right. …

Holocene Palaeohydrology From Testate Amoebae Analysis: Developing A Model For British Peatlands, Wendy Ann Woodland Jan 1996

Holocene Palaeohydrology From Testate Amoebae Analysis: Developing A Model For British Peatlands, Wendy Ann Woodland

School of Geography, Earth and Environmental Sciences Theses

Testate amoebae (Protozoa: Rhizopoda) are particularly abundant in peatlands. Previous studies have used testate amoebae in palaeoenvironmental studies, but have used qualitative data only, so that results are expressed only in terms of 'wet', 'dry' or 'moist'. This study uses testate amoebae to derive quantitative reconstructions of mire surface wetness for part of the Holocene and is split into two parts. The first part of this study modelled the responses of individual testate amoebae species to environmental variables on ombrotrophic mires, since the peatland-climate link makes these habitats the one of the most useful in palaeoclimate reconstructions. 163 samples of …
