Karl E. Schedl

Karl Eduard Schedl (born January 17, 1898 in Lienz , East Tyrol ; † May 18, 1979 there ) was an Austrian zoologist and forest scientist . The forest entomologist gained international fame as one of the leading specialists in bark beetles . He built up one of the most important bark beetle collections in the world. His son is the Innsbruck zoologist Wolfgang Schedl .

Life

Karl E. Schedl attended elementary school in Lienz, then switched to the upper secondary school in Marburg an der Drau . From 1915 to 1918 he took part in the First World War, as Kaiserschützen of the Kk Landesschützenregiment San Candido, initially in South Tyrol and in 1917/18 on the southeast front. After the end of the war, Schedl began studying forest sciences at the University of Natural Resources and Life Sciences in Vienna , which he completed in 1921 as a graduate engineer .

On November 16, 1922, he married Hertha M. Tretzmüller in Vienna. Schedl began his forestry career as a forest judge in Hopfgarten in Defereggen (East Tyrol). He then headed the forestry operations of the Mayr-Melnhof estates in Göss in Styria for five years . This activity was also associated with fighting bark beetles in the Göss-Schladnitz area. This is how Schedl found his future professional field of activity: forest entomology.

From 1926 to 1932 he went to Canada , where he worked as an entomologist for the Entomological Branch of the Department of Agriculture, first in the parasite laboratory in Chatham ( Ontario ), then with the first aircraft control of forest pests . He processed this experience in his dissertation, quantitative field studies on three new Canadian pine sawfly, including a criticism of field test methods in general and a general discussion of quantitative test methods in particular , with which he received his doctorate in 1933 at the University of Natural Resources and Life Sciences in Vienna. He then moved to Munich, where he completed his habilitation at the university in 1934 . During this time he also set up a laboratory near Magdeburg . From 1936 to 1939 he worked as a lecturer for forest entomology and forest protection at the forest university in Hann. Münden . In 1939 he accepted the call to the Eberswalde Forestry University , where he was appointed professor. But the Second World War immediately wrested Schedl from this new sphere of activity, and from 1940 to 1945 he did military service again, later becoming a prisoner of war.

After his release from captivity, Schedl returned to his homeland in Austria, where he initially ran a nuns' forest ward in Upper Styria from 1947 to 1949 . This resulted in the writing Experiences and Observations on the occasion of the nun gradation in Styria in the years 1946 to 1948 (1949). Schedl then headed the Institute for Entomology until his retirement at the end of 1963, which as a branch in Carinthia and East Tyrol was first located in Bodensdorf am Ossiacher See , then from 1954 in Lienz and was responsible for forest protection advice in Carinthia, East Tyrol and Styria. The entomologist returned to his place of birth for professional reasons. Prof. Dipl.-Ing. Died there. Dr. Karl Eduard Schedl on May 18, 1979.

Services

Karl E. Schedl was one of the world's leading specialists in bark and ambrosia beetles , whose morphology , anatomy , systematics and biology he researched intensively for more than four decades. He included not only European, but also African species, and put together one of the most important international collections of these beetles. The “Schedl Collection” is an important part of the scientific collections of the Natural History Museum in Vienna .

He submitted monographs not only on bark beetles, but also on such important forest insects as the gypsy moth , the small spruce needle moth , the spruce nest moth , the small spruce leaf wasp and pine shoot moth . Schedl wrote a total of around 300 publications.
