In this project, it is aimed to calculate the functional feature diversity and species richness depending on some characteristic features of the bird species distributed in Isparta-Gölcük Nature Park and map their relationship with topographic variables. For this purpose, the richness and functional feature diversity of bird species distributed in different habitat types will be investigated. Gölcük Nature Park, which contains the only Caldera (Lake Gölcük) of Southwest Anatolia and has high variations such as different habitat types, bird species and topographic variables, was determined as the study area. The fact that it allows the determination of factors affecting bird species richness and functional feature diversity values and includes different habitat type variations makes this area important.
4 different habitat types determined in this project; It has been designated as Forest, Degraded Forest, Bushland and Agriculture area. During the study, at least 15 different points (with a radius of 25 meters) from each of these habitat types will be determined in different seasons (autumn-winter-spring-summer) and bird observations and identification will be made. In bird observation inventory studies to be carried out at a total of at least 60 points for each different season, 4 different functional feature characters were determined to determine bird functional feature diversity. These characteristic features are Feeding Type, Feeding Layer, Shelter/Nest Location and Morphology. Data on bird characters will be researched and recorded from both field observations and literature sources. With the data on the character traits obtained, bird species richness "S" and functional trait diversity calculations "FAD" will be made. To calculate functional trait diversity, the current "FAD" formula, which expresses the total distances between all species pairs in the area, will be used.
After bird species richness and functional feature diversity calculations are made, the process of creating digital topographic variables needed for modeling and mapping processes will begin. In this process, with the help of different formulas, indexes or Artoolbox of ArcGIS Pro software, slope degrees, aspect degrees, slope classes, aspect classes, elevation, shading index, slope length and steepness factor, aspect suitability index, radiation index, 30m x 30m cell size of the study area. The process of creating 26 different digital base maps, including temperature index, topographic humidity index, ruggedness index, roughness index, solar radiation index, topographic position index, road density index, solar illumination index (9 pieces) and land surface shape index, will be completed.
Thanks to digital topographic maps, bird species richness and functional feature diversity modeling and mapping process will be started. During the modeling phase, the regression tree technique and generalized additive model methods in the RStudio program will be used. In order to carry out the mapping process according to the model results, the numerical values of the variables that structure the model will be used with the help of the created data matrix and model formulas. Based on these numerical values, mapping the richness and functional feature diversity of bird species that prefer different seasons and habitat types within the study area reveals the widespread impact of this project. In addition, this project is an original study by calculating the bird species diversity and functional feature diversity in Turkey and modeling and mapping the relationship between them with topographic variables.
In summary, in this project, bird species richness and functional feature diversity will be compared with functional feature diversity by associating bird species richness and functional feature diversity values with topographic base maps. Unlike master's and doctoral theses, the researcher's concentration on different materials and methods in this project will have a key value in the career development potential of the researcher. In addition, the necessary machinery and equipment for the project will be provided by Isparta University of Applied Sciences. ISUBÜ Sütçüler Prof. Dr. The Consultant's knowledge and experience in bird species richness, functional feature diversity, modeling and mapping processes, working in Hasan Gürbüz Vocational School Forestry Department/Hunting and Wildlife Program and Graduate Education Institute/Forest Engineering Department, will enable the project to be carried out reliably and successfully.
