Calculation procedure for RITY-A phenology model of Ips typographusOgris, Nikica (Avtor) European spruce bark beetlephenologyecological modellingvoltinismpopulation dynamicsThe RITY-2 phenology model was developed for the spatiotemporal simulation of the seasonal development of European spruce bark beetle, Ips typographus . RITY-2 is based on the PHENIPS model and was developed through improving PHENIPS with innovative approaches and calibrating and validating it for Slovenia. RITY-2 predictions are based on air temperatures from Integrated Nowcasting through a Comprehensive Analysis (INCA) system, which is used to calculate the effective bark temperature for beetle development. In this paper we describe the calculation procedure for RITY-2.Elsevier20202020-03-19 12:19:44Znanstveno delo11208UDK: 630*4ISSN pri članku: 2215-0161DOI: 10.1016/j.mex.2020.100845COBISS_ID: 5647270OceCobissID: 13645083sl
