We investigated the potential relationships between foraging strategies and relative brain and brain region volumes in predatory (animal-eating) echolocating bats. The species we considered represent the ancestral state for the order and approximately 70% of living bat species. The two dominant foraging strategies used by echolocating predatory bats are substrate-gleaning (taking prey from surf...

Predators of herbivorous insects play important roles in tropical ecosystemsasherbivorymayaffect structure and diversity of plant populations. Although insectivorous bats are particularly abundant and diverse in the tropics, their impact on herbivorous insects is little understood. To assess prey consumption, we observed the gleaning bat Micronycteris microtis (Phyllostomidae) continuously for ...

Periodically-harvested closures are commonly employed within co-management frameworks to help manage small-scale, multi-species fisheries in the Indo-Pacific. Despite their widespread use, the benefits of periodic harvesting strategies for multi-species fisheries have, to date, been largely untested. We examine catch and effort data from four periodically-harvested reef areas and 55 continuousl...

No business or organisation can remain in ignorance of, or unresponsive to, what is going on its environment and hope to remain successful for very long. This is especially true with regard to the business planning process (Cooke and Slack 1991). Even though a significant amount of decision-making takes place across the boundaries of the organisation concern with the environment within which co...

Correlations of 0.3 and 0.4 in psychological studies in chronic illness (e.g. diabetes) have been criticized as having little clinical importance. The present article suggests that correlation coefficients be interpreted as binomial effect size displays (BESD) as a means of gleaning the clinical importance of a given correlation coefficient. The BESD is easily understood, computed, and applied ...
