Influences Of Adjacent Land-Use On Avian Community Structure In Sub-Boreal Peatlands Of The Midwest, Lucas J. Wandrie Jan 2012

Influences Of Adjacent Land-Use On Avian Community Structure In Sub-Boreal Peatlands Of The Midwest, Lucas J. Wandrie

All Graduate Theses, Dissertations, and Other Capstone Projects

Surrounding land use influences avian community structure; moreover, anthropogenic manipulation of habitat can alter bird species richness and composition. In the first chapter of my thesis work, I conducted avian surveys at 20 sub-boreal peatlands in eastern Minnesota and western Wisconsin to detect correlations between land development and bird community structure. Peatlands are wetlands that accumulate decaying organic plant material (peat) and provide valuable and diverse habitats to a variety of flora and fauna. I measured urban and cropland development at three spatial scales (500 m, 1000 m, and 2500 m radii). Effects of development on avian communities also were …

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert Davis, C Gole, Jd Roberts

Research outputs 2012

Urban development either eliminates, or severely fragments, native vegetation, and therefore alters the distribution and abundance of species that depend on it for habitat. We assessed the impact of urban development on bird communities at 121 sites in and around Perth, Western Australia. Based on data from community surveys, at least 83 % of 65 landbirds were found to be dependent, in some way, on the presence of native vegetation. For three groups of species defined by specific patterns of habitat use (bushland birds), there were sufficient data to show that species occurrences declined as the landscape changed from variegated …


The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster Jan 2012

The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster

Antioch University Dissertations & Theses

The development of management programs for socio-ecological systems that include multiple stakeholders is a complex process and requires careful evaluation and planning. This is particularly a challenge in the presence of intractable conflict. The feral pig (Sus scrofa) in Australia is part of one such socio-ecological system. There is a large and heterogeneous group of stakeholders interested in pig management. Pigs have diverse effects on wildlife and plant ecology, economic, health, and social sectors. This study used the feral pig management system as a vehicle to examine intractable conflict in socio-ecological systems. The purpose of the study was …

Comparative Histological Structure Of The Sinus Node In Mammals, Abolghasem Nabipour Jan 2012

Comparative Histological Structure Of The Sinus Node In Mammals, Abolghasem Nabipour

Turkish Journal of Veterinary & Animal Sciences

The main function of the sinus node is to provide the electrical impulse responsible for normal cardiac rhythm. The rhythmic coordination depends on the passage of the excitation wave by the heart through its conductive system of impulse. There is considerable variability in the size and exact location of the sinus node of individual hearts even within the same species. Histological features of the sinus node including the cells, the nodal artery, the collagen framework, and the innervation, and also some physiological characteristics of the node, will be discussed.

Geostatistical Spatiotemporal Modelling With Application To The Western King Prawn Of The Shark Bay Managed Prawn Fishery, Ainslie M. Denham Jan 2012

Geostatistical Spatiotemporal Modelling With Application To The Western King Prawn Of The Shark Bay Managed Prawn Fishery, Ainslie M. Denham

Theses: Doctorates and Masters

Geostatistical methodology has been employed in the modelling of spatiotemporal data from various scientific fields by viewing the data as realisations of space-time random functions. Traditional geostatistics aims to model the spatial variability of a process so, in order to incorporate a time dimension into a geostatistical model, the fundamental differences between the space and time dimensions must be acknowledged and addressed. The main conceptual viewpoint of geostatistical spatiotemporal modelling identified within the literature views the process as a single random function model utilising a joint space-time covariance function to model the spatiotemporal continuity. Geostatistical space-time modelling has been primarily …
