Demographic changes and people’s distance from nature are causing society to polarize their perception of hunting. Some have ‘’Bambi Syndrome’’ and others so-called ‘’Nature Deficit disorder’’. Factors shaping attitude toward hunting are: sex, age and place of residence: girls and city based children are generally against hunting. Future of wildlife management models largely depends on the attitudes of people towards it in the coming decades. This attitudes are shaping by many different factors but it is lack of knowledge about it. For this purpose, the attitude of young people to hunting should be thoroughly and multidimensionally examined.","PeriodicalId":49464,"journal":{"name":"Sumarski List","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69357572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The morphological and chemical variability of Turkish Hazel (Corylus colurna L.) fruits in Turkey","authors":"Mehmet Kalkan, Mustafa YILMAZ, R. A. Oral","doi":"10.31298/sl.147.1-2.5","DOIUrl":"https://doi.org/10.31298/sl.147.1-2.5","url":null,"abstract":"Turkish hazel (Corylus colurna L.) is naturally distributed in southeast Europe, Anatolia, the Caucasus and Western Himalayas. In Turkey, there are many isolated populations in the Black Sea, Marmara, Aegean, and Central Anatolian Regions. Many of the small populations in Turkey are endangered. In this study, the morphological and chemical characteristics of Turkish hazelnut fruits collected from seven populations were researched. In this regard, considering the morphological characteristics of fruits and kernels, significant differences were observed between the populations. Length, width, thickness, and weight averages were 15.98 mm, 15.38 mm, 12.00 mm and 1.4651 g in the fruits, and 13.03 mm, 11.22 mm, 7.64 mm and 0.5047 g in the kernels, respectively. The average shell thickness was 1.92 mm, shell weight was 0.9604 g, and kernel ratio was 35.16%. Statistically significant differences were found out between the populations whose chemical contents were analyzed. As a result of the analysis, the average fat content, protein, starch, and ash were 64.1%, 15.9%, 10.2 g, and 2.5%, respectively. According to the averages in the obtained fatty acids, the main fatty acids were oleic acid (79.53%), linoleic acid (11.34%), palmitic acid (5.68%), and stearic acid (2.03%), while the rest of other oils were found in trace amounts. Overall, our results suggest that the information relating to morphological and chemical characteristics of Turkish hazelnut can be useful for discriminating among populations.","PeriodicalId":49464,"journal":{"name":"Sumarski List","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47374526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-five half-sib lines were examined, designated according to the number of their mother trees from R1-R35. Twenty measured and derived anatomical parameters were examined, describing stomatal and leaf blade cross-section traits. According to Hierarchical analysis of variance, variation of the majority of characters describing stomatal properties were significantly affected by effect of half-sib lines. The effect of variation between plants within half-sib lines was significant for all examined stomatal traits. However, in cross-section characters, the effect of differences between half-sib lines was significant only for thickness of spongy mesophyll (SL). The discrimination model with seven selected traits achieved 60.5% of correct allocation, while the correct allocation of the model with all 20 examined traits was 81.6%. According to the results of stepwise discriminant analysis, the most powerful trait in discrimination of these half-sib lines were stomatal aperture width/stomatal aperture length ratio (Wb/La) and stomatal aperture length/ stomata guard cell length ratio (La/LA). Presented results strongly support implementation of stomatal and cross-section leaf traits in further studies that would deal with description of variability of Juglans regia.","PeriodicalId":49464,"journal":{"name":"Sumarski List","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69356923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of harvesters in Serbia began in 2008 with John Deere 1470D Eco III and it was used for felling trees and production of wood assortments in poplar plantations in the lowland area. The aim of this paper is to determine maximum profit by engaging a harvester in the given conditions, as well as to determine the total costs of the asset. Harvester achieved a total of 18,392 machine hours (MH), with an average of 1,415 hours per year. The average fuel consumption during the entire period was 16.3 l/h, or 0.76 l/m3. The highest cost of spare parts was in the 6th year (around 66,000 euros) and in the 12th year (around 82,000 euros). The total cost of spare parts and services was 656,878 euros. Based on the planning that the number of work days per year is 200, an amortization period of 7 years is obtained (the point of intersection of current and average profit growth). Results of this research indicate that harvesters older than 7 years should be replaced with new machines, due to high maintenance costs. However, these are only initial researches, which will be continued with data on several harvesters that have been procured in the meantime.","PeriodicalId":49464,"journal":{"name":"Sumarski List","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69356926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obveza liječnika koji je prvi pregledao ozlijeđenog u bilo kojem događaju, pa tako i prometnoj nesreći ili događaju koji ima obilježja ozljede na radu, je prijavljivanje ozljeda policiji. U predmetnoj prijavi, uz opće podatke, liječnik je dužan kvalificirati tjelesnu ozljedu. O klalifikaciji predmetne ozljede ovosit će sve daljne radnje tijekom kriminalističkog istraživanja, te hoće li se pokrenut prekršajni, kazneni ili disciplinski postupak. Na temelju navedenog, primarni cilj istraživanja odnosi se na izradu okvira za kvalitetnije, točnije i ujednačenije kvalificiranje ozljeda sudionika prometnih nesreća. Sekundarni cilj istraživanja vezan je za prikaz trenda i kvalifikacije ostalih ozljeda pri radu u prometu unutar poduzeća koje gospodari državnim šumama. Kod analize općih mehanizama ozljeđivanja i povezanih ozljeda tj. kvalifikacije ozljeda sudionika prometnih nesreća, primijenjena je metoda analize, sinteze, kompilacije i klasifikacije, a kod analize numeričkih podataka primijenjena je tehnika deskriptivne statistike. Rezultati istraživanja vezani za kvalifikaciju ozljeda prikazani su unutar četiri pregledne tablice glede mehanizma nastupanja ozljeda kod frontalnih sudara, bočnih sudara, sudara u vožnji u slijedu i kod prevrtanja vozila. Najveći broj kvalificiranih ozljeda (n=58) utvrđen je kod frontalnih sudara, kod kojih je utvrđen i najveći broj mehanizama ozljeda (n=4). Najmanji broj mehanizama ozljeđivanja (n=1) i najmanji broj kvalificiranih ozljeda (n=7) identificiran je kod sudara u vožnji u slijedu.

In total, 12 natural populations of common hornbeam located in four different watersheds of the Eastern Black Sea Region were sampled from three different altitude zones up to 1200 m a.s.l. Involucres have been examined biometrically by analyzing 13 morphological characteristics. High phenotypic variability was determined both among and within the studied populations. Furthermore, grouping of populations according to the eco-geographic principle was revealed. Variation in most of involucre characteristics from the Camlıhemşin, Çaykara and Trabzon-Maçka watersheds appeared to be related mostly to altitude. The trees in the higher elevations were characterized with the smaller involucres than those in the lower elevations. However, this trend has not been observed in the populations from the Giresun-Espiye watershed. Moreover, trees from that region at lower altitude had the smallest involucres. Overall, our results confirm the Eastern Black see region as one of the hot spots of biodiversity and that the involucre morphological variability is the result of the complex evolutionary process related to the adaptation and plasticity.","PeriodicalId":49464,"journal":{"name":"Sumarski List","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69356968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

U Nacionalnom parku Risnjak dimenzijama se ističu dvije ponikve (Viljska ponikva - VIP i Velika ponikva - VP) gdje smo testirali hipotezu o postojanju značajnih razlika u fiziografiji površinskog dijela tla. Cilj je bio istražiti u kojoj se mjeri uzduž osojne i prisojne padine ponikve mijenjaju kemijske značajke površinskog dijela tla i očituje li se pri tomu i razlika između dviju ponikvi, s obzirom na postojanje razlike u njihovoj litološkoj građi i poziciji unutar gorskog masiva. Istraživanja su provedena tako da je u svakoj ponikvi postavljen transekt u pravcu ~sjever-jug preko dna ponikve, na komu je obavljeno uzorkovanje tla do dubine od 15 cm (ili do stijene, ako je tlo pliće). Pokazalo se da je u VIP izraženija diferencijacija prirode humusa u organičnom horizontu i da ona dobro korespondira s diferencijacijom vegetacije. U VP se fizička trošivost stijena (dolomitični supstrat) odražava na fiziografiji tla u obliku karbonatnosti i više pH-vrijednosti, koja u VIP raste od dna prema rubu ponikve, dok se u VP pH-vrijednost značajno ne mijenja uzduž padina. Na osojnoj ekspoziciji u VIP je udio organskog ugljika u tlu značajno veći (377 g kg–1) od udjela na prisojnoj ekspoziciji (97 g kg–1), pri čemu na osojnoj ekspoziciji udio organskog ugljika opada od dna prema rubu ponikve, a na prisojnoj ekspoziciji se očituje blagi rast. Za razliku od navedonoga, u VP udjel organskog ugljika ima obrnuti trend. Slične odnose i trendove pokazuje i udjel ukupnog dušika, osim pri dnu osojne padine u VIP, gdje je Ntot relativno nizak, a Corg relativno visok.\u0000Zaključno, fiziografija tla dubokih gorskih ponikvi krša pod snažnim je utjecajem prirode stijena u pogledu dolomitičnosti.

U ponikvama u masivima čvrstih vapnenaca može se očekivati na njihovim osojnim padinama karakteristične trendove pH-vrijednosti tla te udjela organskog ugljika i ukupnog dušika zbog vrlo izraženog hidrotermičkog, odnosno bioklimatskog trenda. Na prisojnim ekspozicijama takvih ponikvi analogni trendovi s karakterističnim gradijentima izostaju, što korespondira i s izostankom prepoznatljivog vegetacijskog slijeda.","PeriodicalId":49464,"journal":{"name":"Sumarski List","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49567183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
