Abstract

U sklopu doktorskoga rada istražena je korelacija između karakteristika zajednica primarnih i sekundarnih dupljašica te florističkih i strukturnih karakteristika staništa u nizinskim poplavnim šumama uz rijeku Dravu u Hrvatskoj. Standardna metoda prebrojavanja u točki korištena je za istraživanje zajednica ptica, a metoda kružnih ploha za istraživanje staništa na ukupno 66 točaka. Bazalna površina stabala korištena je kao indikator starosti i za klasifikaciju istraživanih točaka u četiri skupine prema dominantnoj vrsti stabla. Uočena je velika heterogenost staništa. Zabilježeno je ukupno 13 vrsta dupljašica (5 vrsta primarnih i 8 vrsta sekundarnih). Ustanovljeno je da broj vrsta ptica i brojnost populacija ptica dupljašica ovise i o strukturnom i florističkom sastavu šumskih zajednica. Starije šumske sastojine imale su veću raznolikost zajednica ptica i veću gustoću populacija. Ptice su preferirale miješane šume i šume tipa jasena, a florističke karakteristike su imale veći utjecaj na sastav zajednica sekundarnih dupljašica. Broj vrsta i brojnost sekundarnih dupljašica bili su pozitivno korelirani s brojem vrsta i brojnošću primarnih dupljašica. Rezultati rada mogu biti korišteni kao smjernica za održivo gospodarenje šumama.

Abstract (english)

In this doctoral thesis, correlation between primary and secondary hole-nesters community characteristics and floristic and structural characteristics of their habitat was studied in riverine forest stands near river Drava in Croatia. The standard point count method was used to study bird communities, and the circular plot method was used to study habitats at a total of 66 points. The basal surface of the trees was used as an indicator of age, but also to classify the investigated points into four groups according to the dominant tree type. Forest habitat was found to be very heterogeneous. A total of 13 bird species were recorded (5 primary and 8 secondary hole-nesters). Results showed that the number of bird species as well as their abundance depend on both structural and floristic composition of forest communities. Older forest stands had a greater diversity of bird communities and higher population density. Birds selected mixed and ash forest, and floristic characteristics had greater impact on the composition of secondary hole-nesters. The number of species and abundance of secondary hole-nesters were positively correlated with the number of species and the size of the populations of primary hole-nesters. The results of this thesis can be used as a guideline for sustainable forest management.
