![]() Rezultati ovog istraživanja ukazuju da su izvori hrane i interakcije unutar vodenih biocenoza bile glavne odrednice u strukturiranju entomofaune odnosno makrozoobentosa u sastojinama submerznih makrofi ta.īrown trout of non-native lineages have been stocked into Croatian streams and rivers primarily to meet angler demand. Između funkcionalnih hranidbenih skupina detritovori su postigli najveći udio (81 %) u ukupnoj abundanciji. i Diptera (23 % u R1M i R2M) s dominacijom jedinki iz skupine Tanitarsini najviše su pridonijeli ukupnoj abundanciji. Ephemeroptera (R1M 66 %, R2M 76 %) s dominantnom svojtom Cloeon sp. m-2) dok je na postaji R2M maksimum abundancije postignut u proljeće (472 jed. Najveća abundancija postignuta je zimi na postaji R1M (544 jed. Ukupno je utvrđeno 19 svojti, od kojih je 14 svojti bilo prisutno na postaji R1M, a upola manje na postaji R2M. Ostali istraživani čimbenici uglavnom su ukazivali na značajne sezonske razlike. Između ujezerenja nisu utvrđene značajne razlike abiotičkih niti biotičkih čimbenika, izuzev veće abundancije aktivnih fi ltratora u litoralnoj zoni s makrofi tima u ujezerenju 1 (R1M) u odnosu na ujezerenje 2 (R2M). Glavni IZVORNI ZNANSTVENI ČLANCI ORIGINAL SCIENTIFIC PAPERS 8 ciljevi ovog istraživanja bili su analizirati: (i) fi zičko-kemijske čimbenike i izvore hrane (ii) abundanciju i raznolikost te (iii) funkcionalne hranidbene skupine entomofaune. U provedenom istraživanju razmatrana je raznolikost, abundancija i funkcionalne hranidbene skupine akvatičke entomofaune u submerznim sastojinama umjetnih ujezerenja potoka Jankovac (Park prirode Papuk). RADANOVIĆ: Entomofauna sastojina submerznih makrofi ta u umjetnim ujezerenjima (Park prirode Papuk). Littoral zone, Ephemeroptera, Cloeon, Diptera, functional feeding guilds M. ![]() #Jed cyr ed riffle drivers#Results of this study suggested that food resources and biotic interactions are main drivers in structuring entomofauna, i.e., macroinvertebrate community in submerged macrophyte stands. Among feeding guilds the greatest contribution in abundance achieved detritivores (81 %). Ephemeroptera (R1M 66 %, R2M 76 %) with domination of Cloeon sp., and Diptera (23 % in R1M and R2M) with dominated Tanitarsini specimens contributed at most in total abundance. Highest abundance was reached in R1M in winter (544 ind m-2), and in R2M in spring (472 ind m-2). ![]() ![]() In total 19 taxa were identifi ed, among them 14 in R1M, and half less in R2M. Other parameters mostly showed signifi cant seasonal oscillations. Between reservoirs non signifi cant differences were observed in regard to abiotic or biotic parameters, except higher abundance of active fi lterers in vegetated littoral zone of Reservoir 1 (R1M) than in Reservoir 2 (R2M). The main aims of this study were to analyse: (i) physico-chemical parameters and food resources (ii) abundance and diversity and (iii) functional feeding guilds of entomofauna. Two areas Jed considers as areas of interest in his directorship are continuing the availability of multiple uses in a balanced manner and improving access for all residents of the District.In this study diversity, abundance and functional feeding guild of aquatic entomofauna were assigned within submerged macrophyte stands in Jankovac Stream reservoirs (Papuk Nature Park). Jed voted for establishing the District in 1972, and has been a dedicated user of the preserves since they became available for public access. Jed’s experience in school policies made him a seasoned board member immediately, with sage advice and a calm manner. Jed has lived in Sunnyvale for over 35 years. ![]() Jed was first elected to the board of directors, representing the City of Sunnyvale, in 1996 and has served continuously since then. Now retired, Jed taught in the social sciences field at the middle school level in Sunnyvale for 37 years. Jed attended San Jose State University and received a Bachelor of Arts degree in social sciences and a master’s degree in U.S. Jed Cyr was born in San Francisco in 1941 and was raised in Colma. ![]()
