Herbivory Effects On Thalassia Testudinum Leaf Growth And Nitrogen Content, J. C. Zieman, R. L. Iverson, John C. Ogden Jan 1984

Herbivory Effects On Thalassia Testudinum Leaf Growth And Nitrogen Content, J. C. Zieman, R. L. Iverson, John C. Ogden

Integrative Biology Faculty and Staff Publications

The pattern of turtle grazing on Thalassia testudinum in St. Croix seagrass beds begins with the establishment of a grazing plot by initial removal of leaf blades, followed by repeated grazing of several centimeter-long leaf blades within a maintained grazing area. Plants within the grazed area exhibit increased specific growth rate as a consequence of increased light flux to unepiphytized leaf bases. Leaf width is reduced in the grazed area as a consequence of grazing stress. The leaf bases contain a higher proportion of nitrogen and a lower lignin content than the leaf tips, in addition to lacking epiphytes. Our …

Report, Niño As A Natural Hazard: Its Role In The Development Of Cultural Complexity On The Peruvian Coast, August 1983, Joseph J. Lischka Aug 1983

Report, Niño As A Natural Hazard: Its Role In The Development Of Cultural Complexity On The Peruvian Coast, August 1983, Joseph J. Lischka

Natural Hazards Center Collection

"This paper suggests that all the arguments concerning the primacy of maritime vs. agricultural subsistence on the coast during the Cotton Preceramic are overly simplistic. They do not take fully into account the complexity and unique characteristics of the Peruvian coastal environment, and tend to ignore the ability to adapt to temporal environmental variation."


Behavior, Habitat Use, Food, And Foraging Efficiency Of Three Species Of Sympatric Merons (Egretta), Donald M. Kent Aug 1983

Behavior, Habitat Use, Food, And Foraging Efficiency Of Three Species Of Sympatric Merons (Egretta), Donald M. Kent

USF Tampa Graduate Theses and Dissertations

The foraging ecology and behavior of Little Bule Herons (Egretta caerulea), Snowy Egrets (E. thula), and Tricolored Herons (E. tricolor) was studied from October 1981 to August 1982 in Old Tampa Bay and Safety Harbor, Hills borough and Pinellas Counties, Florida. Little Blue Herons foraged exclusively by walk-slow and employed head sways or tilted during 75% of the observations. Snowy Egrets used stand, walk-slow, disturb-and-chase, and foot-stirring. Tricolored Herons used stand, walk-slow, disturb-and-chase, ana stand-and-chase. Tricolored Herons using stand-and-chase stood near shore facing open water and when prey was spotted they ran or hopped in the direction of the prey …
