Quantitative Comparison Of Plant Community Hydrology Using Large-Extent, Long-Term Data, Daniel Gann, Jennifer H. Richards Aug 2015

Quantitative Comparison Of Plant Community Hydrology Using Large-Extent, Long-Term Data, Daniel Gann, Jennifer H. Richards

Daniel Gann

Large-extent vegetation datasets that co-occur with long-term hydrology data provide new ways to develop biologically meaningful hydrologic variables and to determine plant community responses to hydrology. We analyzed the suitability of different hydrological variables to predict vegetation in two water conservation areas (WCAs) in the Florida Everglades, USA, and developed metrics to define realized hydrologic optima and tolerances. Using vegetation data spatially co-located with long-term hydrological records, we evaluated seven variables describing water depth, hydroperiod length, and number of wet/dry events; each variable was tested for 2-, 4- and 10-year intervals for Julian annual averages and environmentally-defined hydrologic intervals. Maximum …


Play As The Foundation Of Human Intelligence: The Illuminating Role Of Human Brain Evolution And Development And Implications For Education And Child Development, Aaron Blaisdell Dec 2014

Play As The Foundation Of Human Intelligence: The Illuminating Role Of Human Brain Evolution And Development And Implications For Education And Child Development, Aaron Blaisdell

Aaron P Blaisdell

Children love to play. Why do they find such a frivolous activity so pleasurable and desirable? Perhaps it is not frivolous, but instead is an adaptation designed to guide proper cognitive development in human children. To understand why, I marshal evidence from different fields to build a case for play as a central behavioral mechanism of human brain and cognitive development. I start with a discussion of human evolution, focusing on the evolution of human physiology, tool-use, the human brain, and life-history strategy, and development, and how these are all connected as an adaptive suite. The anthropological and developmental evidence …
