متن کاملUsing Gall Wasps on Oaks to Test Broad Ecological Concepts
Planning conservation of insect herbivores requires knowing what needs to be conserved and developing a set of predictor variables that aid management. We conducted a state-wide survey to examine the species richness of gall wasps (Hymenoptera: Cynipidae) on six oak species dominant in the threatened scrub-oak vegetation in peninsular Florida. Eighty-eight cynipid species were recorded; 23 were...
متن کاملSTACEY: species delimitation and phylogeny estimation under the multispecies coalescent
This article describes a new package called STACEY for BEAST2 which is capable of both species delimitation and species tree estimation using DNA sequences from multiple loci. The focus in this article is on species delimitation. STACEY is based on the multispecies coalescent model, and builds on earlier software (DISSECT), which uses a ‘birth-death-collapse’ prior to deal with delimitations wi...
متن کاملExploring Species Limits in Two Closely Related Chinese Oaks
BACKGROUND The species status of two closely related Chinese oaks, Quercus liaotungensis and Q. mongolica, has been called into question. The objective of this study was to investigate the species status and to estimate the degree of introgression between the two taxa using different approaches. METHODOLOGY/PRINCIPAL FINDINGS Using SSR (simple sequence repeat) and AFLP (amplified fragment len...
متن کاملChallenges in Species Tree Estimation Under the Multispecies Coalescent Model.
The multispecies coalescent (MSC) model has emerged as a powerful framework for inferring species phylogenies while accounting for ancestral polymorphism and gene tree-species tree conflict. A number of methods have been developed in the past few years to estimate the species tree under the MSC. The full likelihood methods (including maximum likelihood and Bayesian inference) average over the u...
