Estimating Species Richness of Arthropods in Azorean Pastures : the Adequacy of Suction Sampling and Pitfall Trapping
The advantages of the complementary use of suction sampling (Vortis) and pitfall trapping in estimating the species richness of arthropods in sown and semi-natural pastures were investigated on three recent isolated oceanic islands in the Azores. In addition, the ability of pitfall trapping and suction sampling to describe species composition and richness were tested in terms of taxonomic and e...
متن کاملA Composite Interception Trap for Sampling Arthropods in Tree Canopies
A new design of interception trap is presented based on a combination of features ofwindow and Malaise traps. The trap has been developed for study of the canopy faunas of rainforest trees, specifically Argyrodendron actinophyllum. Five such traps have been operated in SE Queensland for a year with catches being removed weekly. Coleoptera, Nematocera, Homoptera and Hymenoptera were the most abu...

gamma -Glutamyl carboxylation: An extracellular posttranslational modification that antedates the divergence of molluscs, arthropods, and chordates.
The posttranslational gamma-carboxylation of glutamate residues in secreted proteins to gamma-carboxyglutamate is carried out by the vitamin K-dependent enzyme gamma-glutamyl carboxylase. gamma-Carboxylation has long been thought to be a biochemical specialization of vertebrates, essential for blood clotting. Recently, a gamma-carboxylase was shown to be expressed in Drosophila, although its fu...
