Monitoring of arthropods focuses typically on changes in population and range size over time. Yet, there are a myriad other aspects that could should be monitored under the ongoing global local environmental change. Stable isotope analysis, widely employed short-term ecological studies, has potential long-term monitoring arthropods. Here we discuss use stable isotopes terrestrial arthropods, pr...

Many studies on the microbiome of animals have been reported but a comprehensive analysis is lacking. Here we present a meta-analysis on the microbiomes of arthropods and their terrestrial habitat, focusing on the functional profile of bacterial communities derived from metabolic traits that are essential for microbial life. We report a detailed analysis of probably the largest set of biochemic...

The Middle Cambrian Spence Shale Member (Langston Formation) and Wheeler and Marjum Formations of Utah are known to contain a diverse soft-bodied fauna, but important new paleontological material continues to be uncovered from these strata. New specimens of anomalocaridids include the largest and smallest near complete examples yet reported from Utah. New material of stem group arthropods inclu...

During the Cretaceous and Jurassic eras (145-65 MYA), blood feeding evolved at least six times in approximately 15,000 arthropod species in 400 genera. Four orders of insects include blood-feeders: Pthiraptera, Siphonaptera, Hemiptera, and Diptera. Some moths (Noctuidae) also feed on blood, and some chewing lice (Mallophaga) and flies with rasping structures in the tips of their probosces will ...
