Southwest Florida Water Management District Healthy Land Equals Healthy Water For grades 6–8 Balancing Water Needs … Protecting Water Resources In order to have a safe and adequate supply of water now and in the future, we must teach our children to be responsible users of Florida’s water resources. This booklet is dedicated to habitats and land resources. Protecting land resources is an effective tool in water management because it helps maintain natural patterns of water storage and movement. Natural areas are important for flood protection, high water quality and recharge of our underground aquifers. This Habitats — Healthy Land Equals Healthy Water booklet outlines the relationship between effective stewardship of the land and our natural water resources. If you would like more information about water resources, contact the Communications Section of the Public Affairs Bureau of the Southwest Florida Water Management District at 1-800-423-1476, ext. 4757, or visit our web site at WaterMatters.org.

  • Interactions Between Organisms . and Environment

    Interactions Between Organisms . and Environment

    INTERACTIONS BETWEEN ORGANISMS . AND ENVIRONMENT 2·1 FUNCTIONAL RELATIONSHIPS An understanding of the relationships between an organism and its environment can be attained only when the environmental factors that can be experienced by the organism are considered. This is difficult because it is first necessary for the ecologist to have some knowledge of the neurological and physiological detection abilities of the organism. Sound, for example, should be measured with an instrument that responds to sound energy in the same way that the organism being studied does. Snow depths should be measured in a manner that reflects their effect on the animal. If six inches of snow has no more effect on an animal than three inches, a distinction between the two depths is meaningless. Six inches is not twice three inches in terms of its effect on the animal! Lower animals differ from man in their response to environmental stimuli. Color vision, for example, is characteristic of man, monkeys, apes, most birds, some domesticated animals, squirrels, and, undoubtedly, others. Deer and other wild ungulates probably detect only shades of grey. Until definite data are ob­ tained on the nature of color vision in an animal, any measurement based on color distinctions could be misleading. Infrared energy given off by any object warmer than absolute zero (-273°C) is detected by thermal receptors on some animals. Ticks are sensitive to infrared radiation, and pit vipers detect warm prey with thermal receptors located on the anterior dorsal portion of the skull. Man can detect different levels of infrared radiation with receptors on the skin, but they are not directional nor are they as sensitive as those of ticks and vipers.

    Microzooplankton and Phytoplankton Distribution and Dynamics in Relation to Seasonal Hypoxia in Lake Erie

    IFYLE05: MICROZOOPLANKTON AND PHYTOPLANKTON DISTRIBUTION AND DYNAMICS IN RELATION TO SEASONAL HYPOXIA IN LAKE ERIE Principal Investigator: Peter J. Lavrentyev Department of Biology University of Akron Akron, OH 44325-3908 Phone: (330) 972-7922 FAX: (330) 972-8445 E-mail: [email protected] Executive Summary: Lake Erie is experiencing extensive hypoxic zones in its central basin despite the reductions in external P loading. The exact mechanisms of hypoxia development and its effects on biological communities including phytoplankton remain unclear. In marine and freshwater environments, the microbial food web (including microzooplankton) plays a key role in hypoxic environments. Microzooplankton have been indicated as an important component of Lake Erie ecosystem, but no data on their response to the seasonal hypoxia and trophic interactions with phytoplankton is available. This project aims to examine the composition, abundance, and growth and grazing-mortality rates of microzooplankton and phytoplankton in conjunction with the planned/ ongoing NOAA research on zooplankton and fish distribution in the three basins of Lake Erie. We will combine real-time flow-cytometric examination of plankton along four nearshore- offshore transects and diel vertical sampling with ship-board experiments at selected contrasting sites to determine plankton response to hypoxia and other environmental factors. Microscopic and molecular tools will be used to verify taxonomic determinations. The project will provide critical information for increasing the knowledge Lake Erie biological processes, improving the existing and future models, and enhancing the government’s ability to manage Lake Erie resources.

Food web structure, mediated by spatial and habitat differences, was examined in a subtropical estuary using stomach content and stable isotope analyses. The goal of this study was to characterize the trophic structure in subtidal oyster reef, intertidal marsh edge, and nonvegetated bottom habitats. Fish and macroinvertebrates were sampled seasonally from July 2006 to April 2007. Spatially, the lower region of the bay supported a more robust food web, with more species and links (72 and 130, respectively) than the upper bay (63 and 87, respectively). Trophic levels (determined by 15N) and carbon sources (determined by 13C) were combined with dietary links (determined by stomach contents), relative population levels, and linkage strength (determined by food volume) to construct 5 dimensional food web diagrams for the 2 regions and 3 habitats studied. The 15N isotope indicated differences in trophic levels and probable nitrogen sources among regions whereas the 13C isotope inferred differences in carbon sources among regions in the Lavaca Bay ecosystem.
