A multigene phylogenetic synthesis for the class Lecanoromycetes (Ascomycota): 1307 fungi representing 1139 infrageneric taxa, 317 genera and 66 families.
TLDR
A multigene phylogenetic synthesis of the Lecanoromycetes based on 642 newly generated and 3329 publicly available sequences revealing relatively stable relationships for many families and orders is provided. Expand
Species boundaries, phylogeography and conservation genetics of the red‐legged frog (Rana aurora/draytonii) complex
TLDR
The results of a survey of 50 populations of red‐legged frogs from across their range plus four outgroup species for variation in a phylogenetically informative, ∼400 base pairs (bp) fragment of the mitochondrial cytochrome b gene point to several major results. Expand
Effects of Local Habitat Characteristics and Landscape Context on Grassland Butterfly Diversity
TLDR
The observations suggest that for the grassland butterfly communities in this study, grassland type was the primary determinant of species richness and composition, habitat quality secondarily affected butterfly community diversity, and landscape context did not significantly predict butterfly species composition. Expand
Soil nutrient effects on oviposition preference, larval performance, and chemical defense of a specialist insect herbivore
TLDR
Results indicate that females may be making sub-optimal oviposition decisions under a nutrient-enriched regime, when predators are present, and these interactions between female preference, larval performance, and larval chemical defense may result in long-term changes in population dynamics and persistence of specialist insects. Expand
Integrating fossil preservation biases in the selection of calibrations for molecular divergence time estimation.
TLDR
A Bayesian extension to the fossil selection approach developed by Marshall (2008) that takes into account a taphonomic bias in the fossil record and has the advantage of identifying calibrations that may bias age estimates to be too recent while incorporating uncertainty in phylogenetic parameter estimates such as tree topology and branch lengths. Expand
Accommodating natural and sexual selection in butterfly wing pattern evolution
TLDR
This study is the first to demonstrate, in a phylogenetic framework, that spatial separation of signals used for mate signalling and those used for predator avoidance is a viable strategy to accommodate multiple signal functions. Expand
A Single Origin for Nymphalid Butterfly Eyespots Followed by Widespread Loss of Associated Gene Expression
TLDR
It is proposed that complex traits, such as eyespots, may have originated via co-option of a large pre-existing complex gene regulatory network that was subsequently streamlined of genes not required to fulfill its novel developmental function. Expand
Distal-less regulates eyespot patterns and melanization in Bicyclus butterflies.
TLDR
It is shown that the characteristic two-eyespot pattern of wildtype Bicyclus anynana forewings is correlated with dynamic progression of Dll, En, and Sal expression in larval wings from four spots to two spots, and that this gene is also a possible selector gene for scale melanization in butterflies. Expand
The molecular phylogenetics of endangerment: cryptic variation and historical phylogeography of the California tiger salamander, Ambystoma californiense
TLDR
The results of a range‐wide survey of genetic variation in the California tiger salamander are presented, as well as a summary of the past several million years of inundation and isolation of the Great Central Valley and surrounding uplands that constitute its limited range. Expand
Candidate gene analysis of metamorphic timing in ambystomatid salamanders
TLDR
These are the first data to implicate a specific gene in contributing to variation in metamorphic timing, and are of particular value in ecological studies where target genes have been identified but the study organism is not one of the few well‐characterized model systems that dominate genetic research.
