Interannual Variability Of Wintertime Sea Surface Temperatures In The Eastern Taiwan Strait, Mu-Tun Tzeng, Kuo-Wei Lan, Jui-Wen Chan Dec 2012

Interannual Variability Of Wintertime Sea Surface Temperatures In The Eastern Taiwan Strait, Mu-Tun Tzeng, Kuo-Wei Lan, Jui-Wen Chan

Journal of Marine Science and Technology

Using Advanced Very High Resolution Radiometer (AVHRR) sea surface temperatures (SSTs) at a 1.1-km spatial resolution, we investigated the long-term SST variability in winter in the eastern Taiwan Strait (TS) in 1995~2008. We performed an empirical orthogonal function (EOF) analysis of spatial and time series variances for 15-day mean images. The first three modes in the EOF analysis respectively accounted for 25.9%, 16.61% and 4.59% of variances. In the first mode, the spatial amplitude showed positive values in the northeastern TS and negative values south of Chang-Yuen Rise (CYR). This suggests that warmer water occurred south of the CYR and …

Journal of Marine Science and Technology

Climate change and climate extremes have a major impact on Australia and Pacific Island countries. Of particular concern are tropical cyclones and extreme ocean temperatures. As a practical response to climate change, through the Pacific Australia Climate Change Science and Adaptation planning Program (PACCSAP), enhanced web-based information tools to provide seasonal forecasts for climatic extremes in the Western Pacific have been developed. Using the dynamical seasonal prediction model POAMA (Predictive Ocean Atmosphere Model for Australia), we aim to improve accuracy of seasonal forecasts of tropical cyclone activity and extreme sea surface temperatures for the Western Pacific. Since the PACCSAP has …


Stream-Associated Amphibian Habitat Assessment In The Portland-Vancouver Metropolitan Region, Andrew Evans Dietrich Dec 2012

Stream-Associated Amphibian Habitat Assessment In The Portland-Vancouver Metropolitan Region, Andrew Evans Dietrich

Dissertations and Theses

This study assessed the influence of landscape development on stream-associated amphibians in forested riparian areas within the Portland-Vancouver metropolitan region. Human alteration of landscapes may dramatically affect the ecology of neighboring aquatic systems. It was hypothesized that lotic amphibians would be negatively associated with greater amounts of landscape development and positively associated with forested area within the surrounding watershed. Thirty-seven 1st-3rd order streams were sampled between June 21st and September 21st in 2011. Streams potentially providing adequate habitat for stream-obligate amphibians were randomly selected. Amphibians were surveyed along 30-meter stream transects using an active-cover search (ACS). Environmental variables associated with …


An Evaluative Framework For Assessing Information Management In Watershed Management: The Case Of The Grand River Conservation Authority (Ontario), Robert Scott Brown Dec 2012

An Evaluative Framework For Assessing Information Management In Watershed Management: The Case Of The Grand River Conservation Authority (Ontario), Robert Scott Brown

Dr Robert Brown

Watershed management has been rapidly evolving over the last 50 years. The current focus has been adaptive and ecosystem-based approaches to watershed management, redefining roles, responsibilities, and relationships of watershed organizations. While entire management models need to be heavily scrutinized, the practices and policies surrounding information are fundamentally important. Information forms the understanding and knowledge for watershed decision-making. Watershed organizations need to be critical of the policies and practices affecting their collection, storage, processing, analysis, monitoring, and reporting of data and information. Among the Conservation Authorities, the GRCA has developed a proficiency at information management, doing it as well as …


Rodent Control Problems In Developing Countries, Robert Z. Brown Dec 2012

Rodent Control Problems In Developing Countries, Robert Z. Brown

Dr Robert Brown

None of the so-called developing countries has an adequate rodent control program at present. In only a few of these countries is any rodent control research occurring despite the fact that rodent problems are actually quite serious in many regions and potentially so in others. Expertise, techniques and materials from the developed countries are of limited usefulness because of major differences in rodent species involved, standards for food handling and sanitation, and in the cultural contexts in which rodent control must occur. Trained personnel, both for control work and the basic research needed, are in very short supply. In addition, …
