Use of tree aggregations in forest ecology and management
Two recent studies using tree aggregations to analyze forest age-structure stability and past forest structure are flawed. A better understanding of aggregation dynamics is needed before aggregation analysis is used in forest management.

Diel and seasonal changes of dissolved oxygen an pH in relation to community metabolism of a shallow reservoir in southeast Missouri
Diel changes of dissolved oxygen (DO) and pH were measured during 1981–1982 in Pool 1, a shallow reservoir in southeast Missouri. Diel changes in spring and fall were about half those of summer when extensive macrophyte biomass apparently had a strong influence on dynamics of DO and pH. During summer, daily pulses averaged 5.45 mg/L DO and 0.88 pH units, and extreme diel changes were 10–14 mg/L DO

Demographic patterns of the shrub Ceanothus megacarpus in an old stand of chaparral in the Santa Monica Mountains
Wildfires have had a major influence on the structural and functional adaptations that have evolved in Mediterranean-type ecosystems. Some chaparral shrubs sprout after fires while others produce serotinous cones or seeds refractory to germination until they are cued by a fire. Ceanothus megacarpus is a sclerophylous shrub commonly found in California in either pure of mixed stands which does no

Long-term on-site and off-site effects of logging and erosion in the Redwood Creek basin, northern California
For nearly 15 years, the Redwood Creek Watershed in north coastal California has been the focus of both U.S. Geological Survey (USGS) and National Park Service (NPS) studies designed to document and quantify the nature of erosion, sedimentation and sediment transport processes active in the basin. While none of these studies were specifically designed to assess possible cumulative effects resulti

Physio-chemical processes affecting copper, tin and zinc toxicity to algae: A review
This chapter focuses on the physic-chemical processes affecting copper, zinc, and tin toxicity to algae. Both Cu and Zn are essential algal micronutrients, cofactors in numerous biochemical processes. The availability of a nutrient or toxic substance can be significantly affected by precipitation. Methods for modeling the effects of adsorption–desorption reactions have been previously reviewed. Us
