The evolution of multimodal communication, where signalers use multiple signal components in multiple sensory modalities, has become the subject of investigation by many researchers. Signaling puts males at risk of predation, so why do males of some species evolve extra signals that may increase this risk? In some wolf spider species, males incorporate many visual and vibrational signals into a display that they use to attract a female for mating. Female spiders are often aggressive toward courting males and so the male display also functions to decrease the odds of cannibalism. Female wandering spiders deposit silk containing pheromones that communicate …

Cropping systems, fertilizer applications and tillage practices influence soil physical and chemical characteristics. In this study, the impact of long-term conventional and no-tillage systems on selected soil properties were evaluated in a continuous corn system on a Maury silt loam soil. This field for the study is located on the University of Kentucky's Research Farm (Spindletop Farm). The field was tilled in 1969 from bluegrass sod and the first year's data was in 1970. Each plot is 20 ft. by 40 ft. and for many years each plot was split with winter cover crop planted to rye or hairy vetch. …
