Making a detour can be advantageous to a migrating bird if fuel-deposition rates at stopover sites along the detour are considerably higher than at stopover sites along a more direct route. One example of an extensive migratory detour is that of the Sharp-tailed Sandpiper (Calidris acuminata), of which large numbers of juveniles are found during fall migration in western Alaska. These birds take a detour of 1500-3400 km from the most direct route between their natal range in northeastern Siberia and nonbreeding areas in Australia. We studied the autumnal fueling rates and fuel loads of 357 Sharp-tailed Sandpipers captured in western Alaska. In early September the birds increased in mass at a rate of only 0.5% of lean body mass day-1. Later in September, the rate of mass increase was about 6% of lean body mass day-1, among the highest values found among similar-sized shorebirds around the world. Some individuals more than doubled their body mass because of fuel deposition, allowing nonstop flight of between 7100 and 9800 km, presumably including a trans-oceanic flight to the southern hemisphere. Our observations indicated that predator attacks were rare in our study area, adding another potential benefit of the detour. We conclude that the most likely reason for the Alaskan detour is that it allows juvenile Sharp-tailed Sandpipers to put on large fuel stores at exceptionally high rates.

This paper explores the collection and collecting activity of the Hawke’s Bay Ph ilosophical Institute of Napier, New Zealand. It examines the development of the Institute’s museum and considers the motivations, intentions and interests of the collectors and their activity within the broader scientific and museum context. The work of two significant collectors is examined in detail: William Colenso, FLS, FRS, missionary, explorer and enthusiastic botanist, who engaged in over fifty years of correspondence and botanical exchange with Sir Joseph Hooker at Kew Gardens; and Augustus Hamilton, the curator of the museum who later became Director of New Zealand’s national collection at the Colonial Museum in Wellington. Through consideration of the Institute’s activities during the period 1874 to 1899, it is proposed that within the collection, the emergence of a distinct local identity can be discerned, during the early colonial period of Hawke’s Bay.

The Sexuality Education and Community Support (SECS) project aims to introduce a P-12 approach to sexuality education at Northern Bay P-12 College (NBC) through a collaborative partnership process between the schools within the College and local, regional, and state health and education agencies and has set out to change current sexual health education practice in the College and assist other schools in the region to do the same. The Project’s goal is a ‘sustainable, responsive, whole school, regionally consistent, best practice sexuality education’. During this first or establishment phase of the SECS project strategies have been implemented to begin the process of building capacity in sexuality education at NBC. These strategies are aimed at developing a sustainable approach during the next three and a half years.

Along Victoria’s coastline there are 30 Marine Protected Areas (MPAs) that have been established to protect the state’s significant marine environmental and cultural values. These MPAs include 13 Marine National Parks (MNPs), 11 Marine Sanctuaries (MSs), 3 Marine and Coastal Parks, 2 Marine Parks, and a Marine Reserve, and together these account for 11.7% of the Victorian marine environment. The highly protected Marine National Park System, which is made up of the MNPs and MSs, covers 5.3% of Victorian waters and was proclaimed in November 2002. This system has been designed to be representative of the diversity of Victoria’s marine environment and aims to conserve and protect ecological processes, habitats, and associated flora and fauna. The Marine National Park System is spread across Victoria’s five marine bioregions with multiple MNPs and MSs in each bioregion, with the exception of Flinders bioregion which has one MNP. All MNPs and MSs are “no-take” areas and are managed under the National Parks Act (1975) - Schedules 7 and 8 respectively.
This report updates the first Marine Natural Values Study (Plummer et al. 2003) for the MPAs in the Port Phillip Bay area of the Victorian Embayments bioregion and is one of a series of five reports covering Victoria’s Marine National Park System. It uses the numerous monitoring and research programs that have increased our knowledge since declaration and aims to give a comprehensive overview of the important natural values of each MNP and MS.

Purpose: To estimate the prevalence of visual impairment, eye disease and eye care in the Alaska Native (AN) population, by demographic and socioeconomic factors.
Methods: Population-based cross-sectional study of 3,793 AN adults aged 18–94 years enrolled in the Education and Research Towards Health (EARTH) Study from March 2004–March 2006. Data on self-reported visual impairment, cataract, glaucoma, diabetic eye disease and previous dilated eye examinations were collected using audio computer-assisted self-administered questionnaires.
Results: The unadjusted prevalence of self-reported visual impairment was 8.7% (95% confidence interval (CI): 7.9–9.7), cataract 5.9% (95% CI: 5.2–6.7), glaucoma 2.5% (95% CI: 2.0–3.0) and diabetic eye disease 1.3% (95% CI: 0.9–1.7). In all cases, age-sex adjusted prevalence estimates for the AN population were greater than available estimates for the general U.S. population. Prevalence of visual impairment and each eye disease increased with age (P < 0.01). Additional factors associated with visual impairment were education and annual household income. Overall, 70.0% (95% CI: 68.5–71.6) of participants reported a dilated eye examination within the previous two years. Dilated eye examination within the previous two years was associated with increasing age (P < 0.001). However, men and participants with lower formal education were less likely to report recent dilated eye examination. Among those with diabetes, only 67.7% (95% CI: 60.8–74.1) reported a dilated eye examination within the recommended previous one year.
Conclusions: Self-reported visual impairment, cataract, glaucoma and diabetic eye disease are prevalent in the AN population. These data may be useful in healthcare planning and education programs.

Currently there is a dearth of research into Australian Indigenous knowledge and their understanding of climate change especially in regard to how it fits into their world view. Recent discussions by the National Climate Change Adaptation Research facility (NCCARF) have highlighted this deficiency but also the need to source relevant research projects that may address this knowledge and perspective, and enable the incorporation of Traditional ecological Knowledge into the planning climate change adaptions strategies in the Port Phillip Bay region thereby increasing their engagement in this discussion. Within this context, this paper examines the use and understanding of landscape, both urban and regional, surrounding Port Phillip Bay and the risks and opportunities climate change adaptation brings to the local Indigenous communities. It synthesises focused interviews with the (Wurundjeri (Yarra Valley), Wathaurong Geelong-Bellarine Peninsular) & Boon Wurrung (Mornington Peninsula)) to elicit a contemporary and local response to issues raised by NCCARF but importantly to articulate a possible Indigenous position about the formation, change and direction that Port Phillip Bay and its environs should take from their perspectives. Research draws upon how these communities have adapted to climate change physically, mentally and spiritually over their long habitation of a shared geological asset and their perceptions of climate change in respect to forecasting and adapting to climate change for this century. The project looks to uncover a longitudinal perspective of change and adaptation focused upon Indigenous views of ‘country’ and traditional custodial obligations to ‘country’ including accumulated cultural and environmental histories.

Background: Chronic diseases and impairments are prevalent among older Americans. However, prevalence data for Alaska Native (AN) elders are limited, with estimates usually extrapolated from national studies in which AN elders may not be well-represented. The aim of this study was to describe the prevalence of selected chronic diseases, impairments, and measured medical risk factors among a large community sample of AN elders.
Methods: Design, setting, and participants. A community-based cross-sectional study of baseline information from 656 AN elders aged 55 years or over who participated in the Alaska Education and Research Towards Health (EARTH) Study, March 2004 to August 2006. Measurements. Self-reported lifetime prevalence of 17 doctor-diagnosed chronic diseases, and point prevalence of vision, hearing, oral, and general health impairment were estimated from data collected using audio computer-assisted self-administered questionnaires. In addition, height, weight, blood pressure, fasting blood lipids, and fasting blood glucose levels were measured.
Results: The four most prevalent chronic diseases among AN elders were high blood pressure (55%), arthritis (49%), high cholesterol (42%), and adult bone fracture/break (35%). The median number of chronic diseases reported was three (inter-quartile range, 2 to 5). The prevalence of self-reported vision impairment was 15%, hearing impairment 18%, and having had all natural teeth removed 25%. Almost 50% were obese. High blood pressure (systolic ≥ 140 mm Hg and/or diastolic ≥ 90 mm Hg) was measured in 23%, high low density lipoprotein (LDL) cholesterol (≥ 130 mg/dL) in 39%, and high fasting plasma glucose (> 125 mg/dL) in 9%. Obesity was more prevalent among women than men. There were also significant regional differences in rates of obesity and high LDL cholesterol.
Conclusion: These data may be useful in public health programs and health services planning.
