Wendy Ziyue Wu Microbial Ecology November 30th, 2016 Prof. Elizabeth Wilbanks Phytoplankton-Bacteria interaction in the Phycosphere Microbiomes Introduction: Defining Phycosphere and its Composition Phytoplankton are autotrophic drifter microorganisms that obtain energy from photosynthesis. They serve as the primary producer for aquatic food web, and are often accredited for their importance in carbon cycling. They are mainly found near the surface of freshwater and diluted seawater environment

Grazing ecosystems support more herbivore biomass than any other terrestrial habitat (Sinclair 1975, Detling 1988, McNaughton et al. 1989, 1991, Huntly 1991). A functional consequence of this disparity in trophic structure emerges by comparing the relationship between aboveground production and herbivore consumption in the Serengeti and Yellowstone ecosystems with that in other terrestrial ecosystems [ILLUSTRATION FOR FIGURE 3 OMITTED]. For consumption measurements, we included plant material removed

Prairie Creek Reservoir, located in an agricultural water in east-central Indiana, serves as a secondary drinking water supply for Muncie, IN and offers various recreational activities. Monitoring of the streams and knowledge of its water quality is very limited. This study assessed water quality at five major tributaries and outfall to support future management decisions. Keywords. — Eutrophication, nutrients, monitoring, streams, reservoir INTRODUCTION In 2014, 43% of all U.S. lakes and reservoirs

The Everglades is a diverse ecosystem located in southern Florida, yet urbanization has created a considerable amount of impact that has altered the physical landscape of the region, resulting in a symbiotic environment between humans and nature. Based on geographical research, the original Everglades spanned an area of approximately 12,000km2, and now because of urbanization and agricultural growth in this sub-region the area of the Everglades has been condensed to half of its original size (Willard

Yellow Perch (Perca flavenscens) Food Chain Dynamics in Lac la Biche, Alberta Proposal Jacob Thalen, Feb, 5, 2015 ThalenJ2@mymacewan.ca MacEwan University, Department of Biology Done in part for the requirements of BIOL 498 under the supervision of Dr. David Locky & Dr. Mrinal Das. MacEwan University, Department of Biology.   Abstract: Trophic cascades are powerful forces that have a pronounced effect on ecosystems. They occur when predation causes shifts in prey dynamics that indirectly

Introduction: Water is not only a necessity to our everyday lives, but it also serves as an important component when it comes to recreation. Knowing how to manage a lake or reservoir for these different aspects is a key ingredient to satisfying our human needs; for survival as well as leisure. Because less than 1% of all water on Earth is safe for humans to drink, it is crucial that these waters be carefully managed to sustain current and future generations. Water-based recreation, such as fishing

Reflective :1 Environmental degradation Any type of activities which alters the systems of the environment and he disturbances caused to air,water,soil and the eco systems is known as environmental degradation. Its under the top ten threats in the united nations panel. Because of environmental degradation illness and premature deaths occur in large numbers. A report says that human health is deteriorating in the past decades. If improvements
