	year = {2018},
	note = {The native eelgrass, Zostera marina, plays a vital role in estuaries, sheltering and providing food for many estuarine inhabitants.  The species has both annual and perennial life cycles.  This paper reports on a population of the annual form of the seagrass.  Minor differences in topography, amounting to only a few centimeters in elevation, had large effects on this population:  lower plants were more abundant, had more shoots per plant and more general biomass than the plants on higher elevations.  Desiccation effects in higher elevations were suggested to be less significant than competition from macroalgae.This article is available from the authors via ResearchGate.},

	journal = {Aquatic Botany},
	volume = {148},
	year = {2018},
	note = {In layperson{\textquoteright}s terms, epiphytes are plants that grow on other plants.  Epiphytes growing on seagrass leaves increase productivity and add food for grazers to the ecosystem. Too many epiphytes, however, shade the host seagrass and interfere with its ability to absorb sunlight. This article reports on a 4-year study of seagrass epiphytes in the lower intertidal of Yaquina Bay, contrasting marine and riverine environments and dry and wet seasons.  },

	note = {Major coastal upwelling events bring water that is low in oxygen and high in nutrients closer to the surface, at times killing marine animals.  Upwelled waters can and do enter estuaries.
