A deeper phylogenetic understanding of ancient patterns of diversification would contribute
to solving many problems in evolutionary biology, yet many of these phylogenies remain …

Phylogenies of major groups of insects based on both morphological and molecular data
have sometimes been contentious, often lacking the data to distinguish between alternative …

Although much biological research depends upon species diagnoses, taxonomic expertise
is collapsing. We are convinced that the sole prospect for a sustainable identification …

This comprehensive, groundbreaking book on the biodiversity of parasites offers a clear and
accessible explanation of how parasite biodiversity provides insight into the history and …

Background Molluscs are the most diverse marine phylum and this high diversity has
resulted in considerable taxonomic problems. Because the number of species in Canadian …

L'identification rapide et sûre de ravageurs d'origine exotique est critique aux fins de
biosécurité. Cependant, l'identification de spécimens sans traits morphologiques distincts …

This study examined subfamilial relationships within Braconidae, using 4 kb of sequence
data for 139 taxa. Genetic sampling included previously used markers for phylogenetic …

Generic concepts in the economically important agarophyte red algal family Gracilariaceae
were evaluated based on maximum parsimony, Bayesian likelihood, and minimum evolution …

Insect parasites and parasitoids are a major component of terrestrial food webs. For
parasitoids, categorization is whether feeding activity is located inside or outside its host, if …

The possibility of gene tree incongruence in a species-level phylogenetic analysis of the
genus Ips (Coleoptera: Scolytidae) was investigated based on mitochondrial 16S rRNA …
