Mayfly

through our everyday lives. In her poem, “The Human Tongue Slows Down to Speak,” Petrosino’s linear narrative evolves into artwork among the pages. Her language picks up speed, “Silted slab, gone white with injury / in decorate dark, in bubbling vault mayflies / blind & basking, lifts itself,” (30) bringing the reader closer into her texts, entering into her fort, her life. Petrosino does this in order to give insight into the mundane, yet extraordinary tasks of everyday life. She takes…

What the stream team will be doing is going to the stream and seeing how much nitrate, phosphates, dissolved oxygen, turbidity, temperature, and pH is in the water. The stream team will look at the effect on water quality, the effect on plants and animals, the acceptable levels for swimming, sources and sources categorized, the best management practices, whether the sources are point source, or nonpoint source pollutants, and the test results. The stream team will be doing all of those topics…

Chapter IV Prey Sensitization, Learning and Memory in Reduviids: Implications in Biological Control 4.1. Introduction Sensitization is an increasing response to a stimulus presented repeatedly while habituation denotes a failure of response to the stimulus (Staddon, 1988). The process of sensitization has enormous adaptive value. When a prey escapes from the clutches of a predator as a result of exhibiting a response, it gets sensitized. If and when a second attempt at capture is initiated by…

As a rule, the gill area is greater in fast-moving crabs (Portunids) than in sluggish bottom dwellers; decreases progressively from wholly aquatic, to intertidal, to land species; and is greater in young crabs than in older crabs. Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current. As in cephalopod mollusks, oxygen utilization is relatively high—up to 70 percent of the oxygen is extracted from the water…
