title: Diel surface temperature range scales with lake size

authors: Woolway, R. Iestyn

abstract: Ecological and biogeochemical processes in lakes are strongly dependent upon water temperature. Long-term surface warming of many lakes is unequivocal, but little is known about the comparative magnitude of temperature variation at diel timescales, due to a lack of appropriately resolved data. Here we quantify the pattern and magnitude of diel temperature variability of surface waters using high-frequency data from 100 lakes. We show that the near-surface diel temperature range can be substantial in summer relative to long-term change and, for lakes smaller than 3 km2, increases sharply and predictably with decreasing lake area. Most small lakes included in this study experience average summer diel ranges in their near-surface temperatures of between 4 and 7°C. Large diel temperature fluctuations in the majority of lakes undoubtedly influence their structure, function and role in biogeochemical cycles, but the full implications remain largely unexplored.

title: Willingness-to-Pay for prescribed fire in the Colorado (USA) Wildland Urban Interface

authors: Kaval, Pamela

subjects: prescribed burning

abstract: During the summer of 2001, survey data were collected from Colorado residents living near public lands (i.e., the wildland urban interface). Data were collected by telephone after mailing respondents a survey. These data include detailed information of respondents’ views towards wildfire management and willingness-to-pay (WTP) values for prescribed burning. Results indicate that Colorado residents living near public lands are aware that fire is a natural process in their area and are in favor of using prescribed burning for fire risk reduction. They also are willing-to-pay an annual tax for prescribed fire undertaken on the public lands near their homes. Respondents’ support for adopting a fire risk mitigation policy based on prescribed fire depended on perceived fire frequency intervals. The substantial WTP values for prescribed burning indicate that the public living in the wildland urban interface could potentially pay an annual tax, so the burden of wildfire management need no longer predominantly lie in the hands of the general taxpayers.

title: Beyond ethics to morality: Choices and relationships in bicultural research settings

authors: Furness, Jane Amanda

subjects: Indigenous methodologies

abstract: Knowledge of ourselves as cultural beings, of the values and beliefs of those with whom we work, and of the history of relations among those in our work settings are essential for community and applied social psychologists. In New Zealand, research by non-Maori involving Maori has often mirrored the harmful colonising practices of the nation’s wider history. In response, several frameworks have been developed setting out conditions and guidelines in which non-Maori might conduct research in Maori settings responsibly and usefully. Nevertheless, views differ on the ways, and extent to which, non-Maori might be involved. Most guidelines do not provide answers to ethical nuances that may arise. This article discusses the experiences of a non-Maori community psychologist engaging in research with Maori participants in a bicultural, but predominantly Maori, school-based community education setting. Insight is provided into how kaupapa Maori approaches were applied in research that was valuable to the community.
