Observations of wing-feather molt and summer feeding ecology of Steller's Eiders at Nelson Lagoon, Alaska Observations of wing-feather molt and summer feeding ecology of Steller's Eiders at Nelson Lagoon, Alaska

The population size, moult chronology, food habits, and feeding behaviour of Steller's Eiders Polysticta stelleri were studied at Nelson Lagoon, Alaska from May to October 1977. Sub-adults were flightless from late July to late August and the adult males were flightless from late August to mid September. Adult females were rarely flightless at Nelson Lagoon but commonly flightless at...

Physio-chemical and morphological characteristics of avian encephalomyelitis virus Physio-chemical and morphological characteristics of avian encephalomyelitis virus

Avian encephalomyelitis virus (AEV) was purified from infected chick embryos by a gradient centrifugation in cesium chloride. The virus had a buoyant density of 1.31 to 1.32 g/ml and a sedimentation coefficient of 148 S. The purified AEV was resistant to treatments with chloroform, acid pH or trypsin. The presence of Mg++ stabilized the virus against heat inactivation (56°C, 1 h)...

Megalagrion paludicola, a new species of damselfly (Odonata: Zygoptera: Coenagrionidae) from Kauai Megalagrion paludicola, a new species of damselfly (Odonata: Zygoptera: Coenagrionidae) from Kauai

A new endemic Hawaiian damselfly, Megalagrion paludicola, is described and illustrated. Adults are found in swampy, low-statured Metrosideros rain forest at 610 m and 1200 m on Kauai I. The nymphs occur in small obscure shaded pools within the swamp.

Tolerance of developing salmonid eggs and fry to nitrate exposure Tolerance of developing salmonid eggs and fry to nitrate exposure

This paper reports on tests which show significant effects on early salmonid life stages of nitrates at levels commonly found in groundwaters in geographical areas that are influenced by fertilizer application. It has long been known, from fish cultural experience, that in certain site specific locations, chronic problems can be expected with salmonid egg development and early fry...
