Eutrophication in shallow coastal bays and lagoons: the role of plants in the coastal filter
Nutrient loading to coastal bay ecosystems is of a similar magnitude as that to deeper, river-fed estuaries, yet our understanding of the eutrophication process in these shallow systems lags far behind. In this synthesis, we focus on one type of biotic feedback that influences eutrophication patterns in coastal bays—the important role of primary producers in the ‘coastal filter’. We discuss the...
متن کاملBeaches, bays and headlands
We consider local and global combinatorial constraints on embeddings of a simple closed curve in a rectangular array of unit squares in which the curve lies entirely within the rectangular array and passes through each unit square once. Geographical terminology is convenient to describe the embeddings. We study shortest segments of the embedded curve with no clockwise quarter turns (bays) and a...
متن کاملClicking in Shallow Rivers: Short-Range Echolocation of Irrawaddy and Ganges River Dolphins in a Shallow, Acoustically Complex Habitat
Toothed whales (Cetacea, odontoceti) use biosonar to navigate their environment and to find and catch prey. All studied toothed whale species have evolved highly directional, high-amplitude ultrasonic clicks suited for long-range echolocation of prey in open water. Little is known about the biosonar signals of toothed whale species inhabiting freshwater habitats such as endangered river dolphin...
متن کاملDevelopment of a Cheap, GPS-Based, Radio-Tracked, Surface Drifter for Closed Shallow-Water Bays
This paper describes the development of an inexpensive (~ $500), GPS-based, radio-tracked, surface-drifter system designed to operate within a closed shallow water bay. Texas bays and estuaries are generally shallow, weather/event driven, complex non-linear systems. In spite of the amount of activity that occurs within the bays, very little real-time information is collected. The Conrad Blucher...
متن کاملAutochthonous production in shallow littoral zones of five floodplain rivers: effects of flow, turbidity and nutrients
1. Comparative research and generalisations in lotic ecology are challenged by the dynamic hydrology of fluvial systems. The aim of this study was to understand more fully how factors such as light, nutrients and flow can predict variation in autochthonous production and algal biomass. 2. We measured seasonal changes in percent bankfull discharge, inorganic nutrient concentrations, turbidity, i...
