Abstract |
Mountains are a big natural lab, where in a relatively small geographic zone the increase in altitude results in a change of the environmental factors which influences the biota of the area. The majority of the scientific works over small mammals concentrates on the altitudinal effects on the fauna from a biogeographical point of view: the relationship between the number of species and the increase in altitude, the altitude-latitude connection etc. Few studies focus on the species ecology and the altitudinal effect on the differentiation of the phenology, maybe because of the effort needed and the differing interests of the researchers.
The main subject of this thesis is the ecology of small mammals along the altitudinal gradient in two mountain massifs of Crete. More specific, this project deals with the phenology of small mammals, especially A. sylvaticus, along the elevation. As well as this, morphological and population data that has been retrieved from the field work is examined. Finally, the last chapter is about the spatial distribution of species in each sampling station as a result of interspecific competition.
This study was carried out in two mountains of Crete, Mt Lefka Ori and Mt Dikti. In each mountain 4 sampling stations were set up, at 400m, 800m, 1200m and 1600m (Mt Dikti) and 1800m (Mt Lefka Ori). All stations are located in the northern part of the mountain ranges and the selection of the locations is based on criteria such as the accessibility and the minimum anthopogenic intervention. Monthly samplings with 100 traps/station were carried out from August 2008 to July 2009, and the Capture-Mark-Recapture (CMR) method was chosen.
In 8800 trapnights, 380 small mammals were captured, of which 175 were recaptures. The captured species were Apodemus sylvaticus, A. mystacinus, Acomys minous, Mus musculus and Crocidura suaveolens.
