Korsgaard And Non-Sentient Life, Gregory L. Bock

Between the Species

Christine Korsgaard argues for the moral status of animals and our obligations to them. She grounds this obligation on the notion that we share a common identity, our animal nature, with them and that animal pain represents a public reason that binds us; nevertheless, her distinctive attempt to enlist Kantian arguments to account for our obligations to animals has a startling implication that she fails to adequately consider: that we have direct duties to plants as well.

American Pika (Ochotona Princeps): Persistence And Activity Patterns In A Changing Climate, Cody P. Massing

Master's Theses

An increasing amount of evidence suggests that as temperatures increase, montane animals are moving upward in elevation (IPCC 2007, Parmesan and Yohe 2003). As suitable habitats rise in elevation and then disappear altogether, these animals could be pushed to extinction. The American pika, Ochotona princeps, is a montane mammal that lives in western North America, usually at elevations above 1500 m (Smith and Weston 1990). Recent evidence suggests that pika population numbers are dropping in response to rising temperatures (Beever et al. 2010). The pika is a small herbivorous lagomorph, a relative of hares and rabbits. Its habitat is …

Traversing Swanton Road, 7th Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

The Integration Of The Ethic Of The Respectful Use Of Animals Into The Law, David Favre

Between the Species

This article develops an ethical construct of “respectful use” to govern the conduct of humans toward animals. The scope of the terms “use” and “respectful” are developed. Some guidelines for the discernment of respectful use of animals are suggested. Then the status of animals within the legal system is briefly considered. Within the law, the socially defined key term is “unnecessary” rather than respectful. Finally, the newer legal standard of duty of care is shown to be approaching the ethical concept of respectful use.

Do Thick Leaves Avoid Thermal Damage In Critically Low Wind Speeds?, A. Leigh, S. Sevanto, M. C. Ball, J. D. Close, D. S. Ellsworth, Charles A. Knight, A. B. Nicotra, S. Vogel

Biological Sciences

• Transient lulls in air movement are rarely measured, but can cause leaf temperature to rise rapidly to critical levels. The high heat capacity of thick leaves can damp this rapid change in temperature. However, little is known about the extent to which increased leaf thickness can reduce thermal damage, or how thick leaves would need to be to have biological significance. We evaluated quantitatively the contribution of small increases in leaf thickness to the reduction in thermal damage during critically low wind speeds under desert conditions.

• We employed a numerical model to investigate the effect of thickness relative …

Strawberry Growth, Yield, Fruit Nutrition, And Control Of Verticillium Wilt With Pre-Plant Soil Fumigants, Ozone, And Biological Control, Justin J. Scurich

Master's Theses

Verticillium wilt is a widespread soilborne disease of strawberry historically controlled by soil fumigation with methyl bromide (MB). MB was banned by the United Nations in 1995 and will be completely phased out by 2015. Research has concentrated on alternative methods of disease control without finding a single alternative able to replace MB in widespread disease control and yield increase. For the current study, strawberries were greenhouse grown in container pots filled with soil from both infested and non-infested areas of a commercial strawberry field in Watsonville, CA. Treatments included pre-plant soil fumigation with commercially available formulations of methyl bromide, …

Towards A Coherent Theory Of Animal Equality, Stijn Bruers

Between the Species

In this article I want to construct in a simple and systematic way an ethical theory of animal equality. The goal is a consistent theory, containing a set of clear and coherent universalized ethical principles that best fits our strongest moral intuitions in all possible morally relevant situations that we can think of, without too many arbitrary elements. I demonstrate that impartiality with a level of risk aversion and empathy with a need for efficiency are two different approaches that both result in the same consequentialist principle of prioritarianism. Next, I discuss that this principle can be trumped by an …
