Lakes restoration approaches

Conservation Ecology: Resilience and restoration of lakes

Lake water quality and ecosystem services are normally maintained by several feedbacks. Among these are nutrient retention and humic production by wetlands, nutrient retention and woody habitat production by riparian forests, food web structures that cha nnel phosphorus to consumers rather than phytoplankton, and biogeochemical mechanisms that inhibit phosphorus recycling from sediments. In deg...

Photochemical approaches to vision restoration

Photoswitches are traditional pharmacologic agonists, antagonists, or channel blockers that are covalently modified with an azobenzene derivative. Azobenzene undergoes wavelength-dependent isomerization between cis and trans conformation. For some photoswitches, only one of these configurations is biologically active, resulting in light-dependent activation or inhibition of function. Photoswitc...

Lake restoration and biomanipulation in temperate lakes: relevance for subtropical and tropical lakes

This introductory chapter to the book “Tropical eutrophic lakes: their restoration and management” gives a summary survey of the responses of temperate lakes to increased nutrient loading (the eutrophication process) and during remediation. Chemically and biologically conditioned resistance may cause a delayed response to the nutrient loading reduction and different methods of overcoming this r...

Perceptually Motivated Approaches to Music Restoration

Spurred by the success of perceptual models in audio coding applications, researchers have recently begun to address audio signal enhancement in a similar manner. Here we consider the case of musical recordings degraded by additive broadband noise such as tape hiss, in which the prevention of signal distortion is tantamount to noise removal. We review perceptually motivated approaches to music ...
