Experimental evidence for sibling recognition in Common Terns (Sterna hirundo)
Young Common Terns (<i>Sterna hirundo</i>) did not respond preferentially to calls of siblings at 8 and 9 days of age, but did so by 12 days of age. In experiments with and without visual isolation, and with use of playback, we demonstrated a tendency to approach sibling begging calls. This differential response indicated sibling-recognition occurred, was based on experience, and involved vocal cu

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

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.

Mortalities of kelp-forest fishes associated with large oceanic waves off central California, 1982-1983
Observations of three incidents of the mass mortality of nearshore fishes are reported; each corresponded to periods of high-amplitude, long-period swells during the 1982-1983 El Niño event along the coast of central California. Members of the nearshore kelp forest fish assemblage, primarily of the genus Sebastes, accounted for 96% of the observed mortalities and S. mystinus (blue rockfish) alone
