Genetics, local environment and health as factors influencing plasma carotenoids in wild American kastrels (Falco sparverius). Proc. R. Soc. Land. (B) 267:1433-1438. — (First Author: Dept Biol., Univ. Saskatchewan, 112 Science Place, Saskatoon, SK, S7N 5E2, CA). The study was conducted in the boreal forest of north-central Saskatchewan (Canada), where a population of ca 150-200 pairs of F. sparverius has been studied since 1988. A total of 5195 prey items was observed, 5070 of which could be identified to some taxonomic level. The major components as a percentage by number (and biomass) of all prey delivered were 10.4 (47.6) small mammals, 63.5 (21.5) Odonata, 3.1 (12.8) birds, 6.4 (9.3) frogs and 5.4 (1.8) grasshoppers.

(Chin., with Engl. s.). — (Dept Life Sci., Shanxi Univ, Taiyuan-030006, China). 12 libellulid spp. are dealt with, but no taxonomic names are stated in figure captions, therefore the identity of the represented spp. cannot readily be ascertained.
