Abundenţa şi distribuţia pe verticală a lumbricidelor din litiera şi humusul unor tipuri de pădure din Masivul Bucegi

  • Subiect: ABUNDANCE AND VERTICAL DISTRIBUTION OF LUMBRICIDAE FROM THE LITTER AND THE HUMUS OF THE TIPES FOREST IN THE BUCEGI MASSIF According to our investigations in the three research stations in the Bucegi massif on the lumbricidae fauna, we conclude the following : 1. Out of the 5 genera and 8 species met in the investigated stations, the only mutual species is Dendrobaena alpina. 2. The station with the greatest number of species collected was the station 1, namely 8 species, and the station with the least number of species was the station 3, namely one species. 3. The species Octolasium lacteum had the species greatest abundance. 4. The species Dendrobaena alpina presents a similar vertical distribution in all the stations, that is the abundance grows from the litter level to the Jitter humus, decreasing in the soil humus. 5. The species Dendrobaena octaedra and Eisenia submontana were more abundant in litter and litter humus. They are surface species and feed on leaves partially or totally decayed. 6. The species Allolobophora rosea and Octolasium lacteum had the largest abundance in the soil humus. They are depth species feeding on detritus organic. 7. Dendrobaena rubida and Lumbricus rubellus were met in a reduced number in the stations 1 and 2.
