Maximum likelihood methods for investigating reporting rates of rings on hunter-shot birds Maximum likelihood methods for investigating reporting rates of rings on hunter-shot birds

It is well known that hunters do not report 100% of the rings that they find on shot birds. Reward studies can be used to estimate what this reporting rate is, by comparison of recoveries of rings offering a monetary reward, to ordinary rings. A reward study of American Black Ducks (Anas rubripes) is used to illustrate the design, and to motivate the development of statistical models for

Occurrence and preservation of Eocene squamariacean and coralline rhodoliths: Eau, Tonga Occurrence and preservation of Eocene squamariacean and coralline rhodoliths: Eau, Tonga

A widespread rhodolith facies occurs within middle Eocene limestones of Eua, Tonga (Fig. 1). These limestones, first described by Hoffmeister (1932), represent a portion of a broad, early Tertiary platform that developed in the Tonga area prior to disruption and uplift by later Tertiary plate movements (Kroenke and Tongilava 1975). Algal rhodoliths form beds several meters thick within...

Organochlorine pesticides in plasma of migrating peregrine falcons at Padre Island, Texas, Spring 1978-80 vs. Spring 1984 Organochlorine pesticides in plasma of migrating peregrine falcons at Padre Island, Texas, Spring 1978-80 vs. Spring 1984

A spring concentration of migrating Peregrine Falcons (Falco peregrinus) was first discovered at Padre Island, Texas, in April 1978. The birds were first captured and blood-sampled for monitoring residue burdens and trends in the late 1970' s. Only 29 Peregrines were sampled in 1978 and 1979, but 111 were sampled in 1980. The initial investigation showed that DDE in the plasma of spring...
