This paper documents various unresolved issues in using surface temperature trends as a metric for assessing global and regional climate change. A series of examples ranging from errors caused by temperature measurements at a monitoring station to the undocumented biases in the regionally and globally averaged time series are provided. The issues are poorly understood or documented and relate to micrometeorological impacts due to warm bias in nighttime minimum temperatures, poor siting of the instrumentation, effect of winds as well as surface atmospheric water vapor content on temperature trends, the quantification of uncertainties in the homogenization of surface temperature data, …

Fisheries Research Reports

Final FRDC report - Project 2002/038

The need for this project was identified through the ESD Risk Assessment workshops held for the Shark Bay and Exmouth Gulf trawl fisheries in May and October 2001. Bycatch issues in the Shark Bay and Exmouth fisheries were identified as a moderate risk through an Ecological Risk Assessment workshop. A better understanding of the faunal composition and habitat preferences of bycatch species in both trawled and untrawled areas has assisted in determining the level of risk to bycatch species. The project provided baseline data on biodiversity and variability of trawl bycatch on and off …

The Distribution And Reproductive Success Of The Western Snowy Plover Along The Oregon Coast - 2007, David J. Lauten, Kathleen J. Castelein, Raya Pruner, Marvin Friel, Eleanor P. Gaines

Institute for Natural Resources Publications

From 3 April – 21 September 2007, we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius alexandrinus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Beach, and New River. Our objectives for the Oregon coastal population in 2007 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) continue selected use of mini-exclosures (MEs) to protect nests from predators …


If Larvae Were Smart: A Simple Model For Optimal Settlement Behavior Of Competent Larvae, Robert J. Toonen, Andrew J. Tyre Nov 2007

If Larvae Were Smart: A Simple Model For Optimal Settlement Behavior Of Competent Larvae, Robert J. Toonen, Andrew J. Tyre

School of Natural Resources: Faculty Publications

Much research has been done on larval settlement cues. Rather than having simple fixed responses to constant environmental stimuli, it seems likely that settlement decisions made by individual larvae should vary depending on the individual and the conditions under which it encounters that cue. Here, we present a simple stochastic dynamic programming model that explores the conditions under which larvae may maximize their lifetime fitness by accepting lower quality habitat rather than continuing to search for superior habitat. Our model predicts that there is a relatively narrow range of parameter values over which larval selectivity among habitat types changes dramatically …

Fisheries Research Report No. 168 - Sustainable Development Of Barramundi Cage Aquaculture At Lake Argyle., Brett Glencross, S. Percival, B. Jones, J Hughes

Fisheries Research Reports

Final FRDC report and KSRP report - Project 2003/026

A preliminary sensory evaluation study was conducted to confirm the presence of a taint issue. Prior to this the issue was reliant on purchaser feedback and was not verified independently. To examine the issue of flavour taint a series of barramundi samples were collected from Lake Argyle (purged and unpurged), wild (estuarine) and marine farmed barramundi were assessed. No significant differences in flavour attributes and/or acceptability attributes were detected between the wild and farmed barramundi, provided the barramundi was either marine-farmed or purged. However, it was determined that a clear “muddy” …

Tourism In Lugu Hu: Helpful Or Harmful? Examining The Impact Of Tourism On Lugu Lake’S People And Environment, Joana Chan Oct 2007

Tourism In Lugu Hu: Helpful Or Harmful? Examining The Impact Of Tourism On Lugu Lake’S People And Environment, Joana Chan

Independent Study Project (ISP) Collection

Is tourism a boon or burden to the land and the people that it impacts? This question has plagued academics for ages. On the one hand, tourism brings not only definite economic growth for the local people, but also motivation for preservation of the local landscape. On the other hand, the arrival of tourists also ironically brings definite cultural and environmental transformations to the very people and land that visitors travel so far to see and experience.

My research examines the complexities of tourism and its impact on the environment and people of Lugu Lake, Yunnan. By surveying social and …

Why Logging? A Value Assessment Of Forestry Uses In The Huon Forest District, Ryan Bailey Oct 2007

Why Logging? A Value Assessment Of Forestry Uses In The Huon Forest District, Ryan Bailey

Independent Study Project (ISP) Collection

The Huon Forest District comprises 762,800 hectares of forests in southwest Tasmania, with 128,900 hectares of that total designated as state forest managed by Forestry Tasmania. These forests are used primarily for wood production, although tourism, carbon storage, leatherwood honey and the specialty timbers industry are competing for access to these forests. This study examines the socio-economic values of these uses and determines whether the Huon Forest District is being utilized efficiently.

To accomplish this, an extensive literature review of past research was conducted. This information supplemented 7 semi-structured interviews that were conducted with experts from the forestry industry, tourism …

Fisheries Research Reports

A preliminary assessment of stock enhancement of Haliotis laevigata (Greenlip abalone) in Western Australia was undertaken with the release of 6,000 abalone near Augusta in 2004. The objective of the project was to obtain quantitative data on the likelihood of enhancement, as an additional management tool to TACs and size-limits, being successful in natural habitats in Western Australia. Baseline surveys coupled with an assessment of growth and survival of released 1+ and 2 + animals were undertaken at 12 sites within Flinders Bay, Augusta. Overall survival was 19% for 1+ age abalone and 27% for 2+ animals after 9 months. …


The Price Of Gold: The Environmental Impacts Of Toxic Chemicals In Gold Mining, Adam Goetz Oct 2007

The Price Of Gold: The Environmental Impacts Of Toxic Chemicals In Gold Mining, Adam Goetz

Independent Study Project (ISP) Collection

The role of mercury and cyanide in gold mining has become a hot topic in Mongolia in the past few years. In the past few months, the government has launched a crackdown on the illegal use of these chemicals in response to the contamination of Khongor soum’s drinking water which resulted from an illegal mining operation. However, there are many more sites throughout the country that are in need of cleaning as a result of the illegal use of these chemicals by small companies as well as individual miners.

This paper examines the role of a variety of different views …
