Entomofauna szyszek i nasion swierka pospolitego Picea abies [L.] Karst. w wybranych drzewostanach Gorczanskiego Parku Narodowego. Czesc II. Wplyw wysokosci n.p.m. i zmiennego obradzania drzewostanow swierkowych na wybrane gatunki owadow

The composition of cone- and seed entomofauna of Norway spruce Picea abies (L.) Karst. of the Gorce National Park was determined between 1998 and 2000. Cones collected from trees at different altitudes and a variable cone crop abundance. Rearing and analysis of 3,600 cones yielded 17,803 insect specimens from 5 orders. Some of the data were analyzed statistically using tests at the significance level a = 0.05. There was a significant correlation between the mean number of these insects and the intensity of cone production. Elevation a.s.l. had not a significant influence on the number of these insects.
