TLDR
Water-soluble extractives from western red cedar heartwood, bark, and foliage were investigated for their toxicity to aquatic organisms and Fry were found to be the stage of development of coho salmon most sensitive to the tropolones, and eyed eggs the least sensitive.
Abstract
Water-soluble extractives from western red cedar heartwood, bark, and foliage were investigated for their toxicity to aquatic organisms. The heartwood lignans and bark extractives were found to be ...

Ecology of Coarse Woody Debris in Temperate Ecosystems

TL;DR: In this article, the authors reviewed the rates at which coarse wood debris is added and removed from ecosystems, the biomass found in streams and forests, and many functions that CWD serves.

Large woody debris in forested streams in the Pacific Northwest: past, present, and future

TL;DR: In this paper, the form, function, and management of woody debr is discussed in streams, and three major conclusions are reached: (1) Large wood debr enhances the quality of fish habitat in all sizes of stream, (2) Removal of most t r ees in the riparian zone dur ing logging, combined with thorough stream cleaning and shortrotation timber ha rves t, has al tered the sources, delivery mechanisms, and redistr ibution of debr, leading to changes in fish population abundance and species composition.

Geographical and Historical Comparisons of Neotropical Streams: Biotic Diversity and Detrital Processing in Highly Variable Habitats

TL;DR: Diversity of stream-dwelling detritivorous fishes is apparently highest in the large, geomorphologically complex Amazon basin where environmental conditions have remained highly variable throughout the Pleistocene, and diversity of other neotropical fish communities is regionally influenced by proximity to marine coastal habitats.

Phenolics in aquatic ecosystems: A selected review of recent literature

TL;DR: The effects of pentachlorophenol on blood glucose and blood lactate levels, and in vivo and in vitro activity levels of seven liver enzymes of eels are discussed, and factors affecting the loss of phenolics from aquatic ecosystems include photolysis, adsorption and dilution.
