Hamiltonian formulations of quasilinear theory are presented for the cases uniform and nonuniform magnetized plasmas. First, standard Kennel Engelmann (Kennel, Phys. Fluids, 1966, 9, 2377) is reviewed reinterpreted in terms a general formulation. Within this representation, we present transition from two-dimensional diffusion spatially background plasma to three-dimensional based on our previou...

Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders. Kleptoparasites are found among spiders as well as among Mecoptera, Diptera, Lepidoptera, and Heteroptera. Predators are found within spiders’ own population (c...
