    An introduction to biodiversity concepts for environmental economists

    Biodiversity is a valuable, but poorly understood, natural resource, which is being lost at an accelerating rate as a result of human actions. We present a broad, introductory review of biodiversity concepts. Biodiversity is first defined at the species and community levels. Available methods and approaches for quantifying biodiversity are discussed with specific reference to the spatial scales over which these measures can be applied. Dominant threats to biodiversity are reviewed. Fundamental patterns and processes that underlie ecological production functions are outlined.

    Female mate assessment and choice behavior affect the frequency of alternative male mating tactics

    Explanations for the existence of alternative male mating tactics focus primarily on male¿male competition. Mating systems, however, are composed of interactions both within and between the sexes, and the role of female behavior in shaping male mating tactics should not be overlooked. By using a dynamic state variable game model, I examine how female mate assessment and choice behavior affect the frequency of alternative male mating tactics.

    Behavioural defences against sexually transmitted diseases in primates

    Sexually transmitted diseases (STDs) are known to exist in wild and domesticated animals, but little is know about behavioural defences that animals use to reduce the risk of acquiring STDs. Using comparative data and a phylogeny of primates, I investigated whether behaviours hypothesized to reduce STD transmission are correlated with measures of STD risk involving mating promiscuity and life-history traits.
