Notes on some United States grasshoppers of the family Acrididae

Immersion Tolerance in Rangeland Grasshoppers (Orthoptera: Acrididae)

PLANTÐINSECT INTERACTIONS Host Preferences and Habitat Associations of Some Florida Grasshoppers (Orthoptera: Acrididae)

Host-plant preferences were assessed by Þeldmeasurement of grasshopper abundance in relation to measurements of ßoral community and by laboratory host-plant preferences. Correlations between grasshoppers and plants (biomass and percentage cover) were based on data gathered at 29 study sites in Þve distinct Florida habitats (including disturbed, freshwater marsh, high pine, oak hammock, and swam...

Health System Reform in the United States

In 2010, the United States adopted its first-ever comprehensive set of health system reforms in the Affordable Care Act (ACA). Implementation of the law, though politically contentious and controversial, has now reached a stage where reversal of most elements of the law is no longer feasible. The controversial portions of the law that expand affordable health insurance coverage to most U.S. cit...

Rensch's rule is not verified in melanopline grasshoppers (Acrididae)

Sexual size dimorphism (SSD) is almost universal in animals. Rensch’s rule proposes that SSD increases with increasing average body size in taxa where males are larger than females (malebiased SSD; MBSSD) and decreases when females are larger (femalebiased SSD; FBSSD). Although it was proposed that both patterns are part of the same evolutionary trend, there is more evidence for Rensch’s rule i...

Host Selection by Grasshoppers (orthoptera: Acrididae) Inhabiting Semi-aquatic Environments

Through laboratory choice tests involving 19 plant species, we assessed the host selection behavior of six grasshopper species: Stenacris vitreipennis (Marschall) (glassywinged toothpick grasshopper), Leptysma marginicollis (Serville) (cattail toothpick grasshopper), Gymnoscirtetes pusillus Scudder (little wingless grasshopper), Paroxya clavuliger (Serville) (olivegreen swamp grasshopper), Paro...
