UK guidelines on the management of variceal haemorrhage in cirrhotic patients
These updated guidelines on the management of variceal haemorrhage have been commissioned by the Clinical Services and Standards Committee (CSSC) of the British Society of Gastroenterology (BSG)Expand

Phylogeny of the parasitic microgastroid subfamilies (Hymenoptera: Braconidae) based on sequence data from seven genes, with an improved time estimate of the origin of the lineage.
The microgastroid complex of braconid wasps is a widely recognized and biologically coherent lineage of endoparasitoids of lepidopteran larvae (caterpillars). The complex has received significantExpand

Systematics, evolution, and biology of scelionid and platygastrid wasps.
The Platygastroidea comprises two families of parasitoids, Scelionidae and Platygastridae, and nearly 4500 described species. They parasitize a diverse array of insects as well as spiders. IdiobiontExpand

Synopsis of Australasian Microgastrinae (Hymenoptera : Braconidae), with a key to genera and description of new taxa
The genera of microgastrine braconid wasps present in the Australasian region (defined as Australia, New Zealand, New Caledonia, New Guinea, Solomon Is, Fiji Is, Samoan Is, Cook Is, but not FrenchExpand

Frequent Mitochondrial Gene Rearrangements at the Hymenopteran nad3–nad5 Junction
We characterized the organization of mitochondrial genes from a diverse range of hymenopterans. Of the 21 taxa characterized, 12 had distinct, derived organizations. Some rearrangements wereExpand

The function of spider egg sacs in relation to parasitoids and predators, with special reference to the Australian fauna
The function of spider egg sacs is analysed as structures to reduce or prevent mortality by parasitoids and predators. The host relationships of the groups concerned are documented, with specialExpand

Subterranean archipelago in the Australian arid zone: mitochondrial DNA phylogeography of amphipods from central Western Australia
In 1998, a unique subterranean ecosystem was discovered in numerous isolated calcrete (carbonate) aquifers in the arid Yilgarn region of Western Australia. Previous morphological and genetic analysesExpand

Increased congruence does not necessarily indicate increased phylogenetic accuracy--the behavior of the incongruence length difference test in mixed-model analyses.
Comprehensive phylogenetic analyses utilize data from distinct sources, including nuclear, mitochondrial, and plastid molecular sequences and morphology. Such heterogeneous datasets are likely toExpand

Increased genetic diversity in mitochondrial genes is correlated with the evolution of parasitism in the Hymenoptera
A higher AT content and rate of mtDNA sequence divergence was found in parasitic wasps (Apocrita) compared with nonparasitic wasps (Symphyta). The compositional bias was reflected in extreme codonExpand
