Employing Philosophical Dialogue in Collaborative Science
ABSTRACT Integrated research across disciplines is required to address many of the pressing environmental problems facing human societies. Often the integration involves disparate disciplines,…
The utility of amplified fragment length polymorphisms in phylogenetics: a comparison of homology within and between genomes.
It is concluded that AFLP data are best suited for examining phylogeographic patterns within species and among very recently diverged species.
Pattern and timing of diversification in Yucca (Agavaceae): specialized pollination does not escalate rates of diversification

The results indicate that the pollination mutualism did not accelerate diversification, as Yucca diversity is not significantly greater than that of its non-moth-pollinated sister group, Agave sensu latissimus, and corroborate the suggestion that the plant–moth pollination Mutualism has at least two origins within the Agavaceae.

Plant polyploidy provides a potential route out of specialization as an evolutionary dead end in phytophagous insect taxa as well as a potentially important route to subsequent phylogenetic and geographic diversification of plant/insect interactions.
Testing for coevolutionary diversification: linking pattern with process.

This review highlights potential mechanisms of coevolutionary diversification, outline approaches to examine this process across temporal scales, and proposes a set of minimal requirements for demonstrating coevolved diversification.
Geographic isolation trumps coevolution as a driver of yucca and yucca moth diversification.

It is concluded that biogeographic factors are the overriding force in plant and pollinator moth speciation and significant phylogenetic congruence between the moth and plant lineages is likely due to shared biogeography rather than coevolution.
EXAMINING GENETIC STRUCTURE IN A BOGUS YUCCA MOTH: A SEQUENTIAL APPROACH TO PHYLOGEOGRAPHY

It is suggested that performing a suite of analyses that focus on different temporal scales may be an effective approach to investigating the patterns and causes of genetic structure within species.
A test of host‐associated differentiation across the ‘parasite continuum’ in the tri‐trophic interaction among yuccas, bogus yucca moths, and parasitoids

The results suggest that Eusandalum may be best viewed as a predator, as female wasps are able to utilize any moth species present at a given locality, and there is little likelihood that host specialization may facilitate population subdivision and speciation.
Scale dependence of vegetation–environment relationships: a meta-analysis of multivariate data
Questions How does spatial scale (extent and grain) influence the relative importance of different environmental factors as determinants of plant community composition? Are there general scale…
Does parasitoid attack strategy influence host specificity? A test with New World braconids
- D. M. Althoff
- 1 August 2003
Abstract. 1. Parasitoid attack strategy has been divided into two broad categories, koinobiosis and idiobiosis, based on the arrest of host development and the intimacy of larval contact.…
