Novi nalazi tulara (Insecta, Trichoptera) za Hrvatsku: vrste Oecetis furva (Rambur, 1842) and Orthotrichia tragetti (Mosely, 1930)

Two species, Oecetis furva and Orthotrichia tragetti, are recorded for the first time in Croatia. Moreover, O. tragetti is recorded for the first time in the limno-ecoregion Hungarian Lowlands (ER11). Adult caddisflies were collected from 2010 to 2012 in Kopački rit Nature Park. Sampling was conducted using light traps (15 W UV lamp) that were operated monthly, with the exception of May when two light trap samples were taken. Both species were collected at various habitats, from both perennial and ephemeral bodies of water (river course, lake, channels). O. furva was collected on the lower reach of the Drava River, in the eutrophic Lake Sakadaš and in two different channels; Vemeljski dunavac (intermittent channel) and Čarna (perennial reclamation channel). O. tragetti was collected in the eutrophic Lake Sakadaš and the Čarna channel. These data represent a significant contribution to the general knowledge of caddisflies in Croatia, and particularly of insufficiently investigated wetlands and lakes in the continental region.Vrste Oecetis furva i Orthotrichia tragetti po prvi puta su zabilježene za faunu Hrvatske. Osim toga, vrsta O. tragetti prvi puta je zabilježena u Panonskoj ekoregiji (ER11 Mađarska nizina). Odrasle jedinke tulara prikupljane su u periodu od 2010. – 2012. godine na području Parka prirode Kopački rit. Uzorkovali smo jednom mjesečno, uz izuzetak svibnja kada smo uzorkovanja obavili dva puta. Kao atraktant koristili smo UV lampu jačine 15 W. Obje su vrste zabilježene na različitim tipovima stalnih i povremenih staništa (riječni tok, jezero, različiti kanali). Vrsta O. furva zabilježena je na donjem toku rijeke Drave, zatim na eutrofnom jezeru Sakadaš, te na dva različita tipa kanala; Vemeljski dunavac (povremeni kanal) i Čarna (stalni melioracijski kanal). Vrsta O. tragetti zabilježena je na eutrofnom jezeru Sakadaš i kanalu Čarna. Ovi podatci predstavljaju značajan doprinos poznavanju faune tulara Hrvatske općenito, a posebice nedovoljno istraženih močvarnih i jezerskih staništa kontinentalnog dijela Hrvatske

Novi podaci o vodenim muhama plesačicama (Empididae: Clinocerinae i Hemerodromiinae) iz Bosne i Hercegovine

Adult aquatic dance flies (Empididae) were collected during April 2006, October 2007 and July 2012 in Bosnia and Herzegovina using sweep nets and by aspirator. Sampling was done on six sampling sites. From 15 species recorded in this study, 5 are new to the fauna of Bosnia and Herzegovina: Roederiodes macedonicus Wagner & Horvat, Wiedemannia (Philolutra) queyrasiana Vaillant, Wiedemannia sp. A, Chelifera flavella (Zetterstedt) and Chelifera siveci Wagner. Overall 40 species are presently known from Bosnia and Herzegovina, belonging to 9 genera. This study represents a contribution to the knowledge of aquatic dance flies and especially of endemic species of the Dinarides and Balkan Peninsula and their present distribution.Vodene muhe plesačice su sakupljane entomološkom mrežicom i aspiratorom tijekom travnja 2006., listopada 2007. i srpnja 2012. godine. Uzorkovanje je provedeno na šest lokacija. Od 15 sakupljenih vrsta u ovom istraživanju, 5 vrsta su novi nalazi za faunu Bosne i Hercegovine: Roederiodes macedonicus Wagner & Horvat, Wiedemannia (Philolutra) queyrasiana Vaillant, Wiedemannia sp. nov., Chelifera flavella (Zetterstedt) i Chelifera siveci Wagner. Do sada je zabilježeno 40 vrste iz 9 rodova. Ovo istraživanje pridonijet će boljem poznavanju faune vodenih muha plesačica, a osobito endema Dinarida i Balkanskog poluotoka te njihove rasprostranjenosti

Prvi podaci o fauni tulara (Insecta: Trichoptera) cretova u Hrvatskoj

Peatlands in Croatia are rare, small in size and isolated habitats. Due to the abandonment of traditional and management practices, and particularly to the progressive vegetation succession, they are critically endangered. Caddisfly faunistics and ecology of peatlands in Croatia have never been studied. A total of seven caddisfly taxa were collected in this study at three different peatlands; Dubravica bog, Đon močvar bog and Jarak fen. The collection of Adicella reducta (McLachlan, 1865) represents a new record for the Croatian caddisfly fauna. Additionally, two tyrphophilous species, Hagenella clathrata (Kolenati, 1848) and Rhadicoleptus alpestris (Kolenati, 1848), were recorded for the first time in Croatia since an imprecise literature record from 1935 and two previous findings (from 1929 and 1997), respectively. Caddisfly larvae were also collected in two peatlands, belonging to the genera Beraea Stephens, 1836 and Ernodes Wallengren, 1891, which are oft en collected at peatbogs in larval stages.Cretovi su u Hrvatskoj rijetka i izolirana staništa male površine. Kritično su ugroženi zbog napuštanja tradicionalnih poljoprivrednih djelatnosti, a posebno vegetacijske sukcesije. U Hrvatskoj nisu provedena istraživanja faune i ekologije tulara na cretovima. Tijekom istraživanja prikupljeno je sedam različitih svojti tulara na tri različita creta; Dubravica, Đon močvar i Jarak. Vrsta Adicella reducta (McLachlan, 1865) predstavlja prvi nalaz za faunu Hrvatske. Nadalje, zabilježene su i dvije tirfofilne vrste, Hagenella clathrata (Kolenati, 1848) i Rhadicoleptus alpestris (Kolenati, 1848). Vrsta R. alpestris zabilježena je do sada u Hrvatskoj samo s dva primjerka (1929. i 1997. godine), dok za vrstu H. clathrata postoji samo neprecizan literaturni navod iz 1935. godine. Na dva creta prikupljene su i ličinke tulara iz rodova Beraea Stephens, 1836 i Ernodes Wallengren, 1891 koje često obitavaju na cretovima

Peeling the Layers of Caddisfly Diversity on a Longitudinal Gradient in Karst Freshwater Habitats Reveals Community Dynamics and Stability

Freshwater biodiversity is facing a severe crisis due to many human impacts, yet the diversity dynamics of freshwater communities and possibilities of assessing these are vastly unexplored. We aimed at emphasizing different aspects of portraying diversity of a species-rich, aquatic insect group (caddisflies ; Trichoptera) across four different habitats in an anthropogenically unimpacted, connected karst barrage lake/riverine system. To define diversity, we used common indices with pre-set sensitivity to species abundance/dominance ; i.e., sensitivity parameter (species richness, Shannon, Simpson, Berger-Parker) and diversity profiles based on continuous gradients of this sensitivity parameter: the naïve and non-naïve diversity profiles developed by Leinster and Cobbold. The non-naïve diversity profiles show diversity profiles with regard to the similarity among species in terms of ecological traits and preferences, whereas the naïve diversity profile is called mathematically “naïve” as it assumes absolute dissimilarity between species that is almost never true. The commonly used indices and the naïve diversity profile both ranked the springs as least diverse and tufa barriers as most diverse. The non-naïve diversity profiles based on similarity matrices (using feeding behavior and stream zonation preferences of species), showed even greater differences between these habitats, while ranking stream habitats close together, regardless of their longitudinal position. We constructed the Climate Score index (CSI) in order to assess how diversity and species’ vulnerability project the community’s resistance and/or resilience to climate change. The CSI ranked the springs as most vulnerable, followed by all habitats longitudinally placed below them. We highlight the importance of integrating ecological information into biodiversity and vulnerability assessment of freshwater communities

Nove vrste tulara (Trichoptera, Insecta) Hrvatske iz Nacionalnog parka Plitvička jezera

Apatania muliebris and Hydroptila rheni were recorded in Croatia for the first time. Both species were collected in the Plitvice Lakes National Park using emergence traps: A. muliebris at the spring of the Bijela rijeka River and H. rheni at the Korana River. These records significantly contribute to data on the caddisfly fauna of Croatia, and in addition extend our knowledge on the distribution and ecology of these species.Vrste Apatania muliebris i Hydroptila rheni zabilježene su prvi put u Hrvatskoj. Obje su prikupljene u Nacionalnom parku Plitvička jezera uz pomoć emergencijskih klopki. Vrsta A. muliebris prikupljena je na izvoru Bijele rijeke, a vrsta H. rheni na postaji na rijeci Korani. Ovi podaci predstavljaju značajan doprinos poznavanju faune tulara Hrvatske, ali i općenito znanju o rasprostranjenosti i ekologiji ovih dviju vrsta

Drusus chrysotus (Rambur, 1842) (Trichoptera: Limnephilidae: Drusinae), nova vrsta tulara za faunu Hrvatske

Drusus chrysotus is a cold water stenotherm species inhabiting spring reaches and headwaters of mountain streams. It has a disjunct distribution range covering mountain ranges across central Europe, and has now been recorded for the first time in Croatia, in the Gorski kotar region, thus extending its distribution range to the Dinaric Western Balkan ecoregion (sensu Illies, 1978). D. chrysotus was collected at the spring of the Dobra River, which is heavily impacted by human activity. Due to the specific aquatic insect fauna of this spring, conservation and prevention of further habitat alteration of this section of the river Dobra River should be a priority for the local community.Vrsta Drusus chrysotus je stenoterm koji naseljava hladne vodotokove, tj. izvore i izvorišne dijelove planinskih potoka. Ima disjunktni areal i rasprostranjena je u planinskim područjima Središnje Europe. Sada je prvi puta zabilježena u Hrvatskoj, u Gorskom kotaru, što predstavlja proširenje njezinog areala na ekoregiju Dinaridski zapadni Balkan (sensu Illies). Vrsta D. chrysotus prikupljena je na izvoru Dobre, koji je pod jakim antropogenim utjecajem te je značajno izmijenjen. Obzirom na vrlo specifičnu faunu vodenih kukaca ovog izvora, zaštita i sprječavanje daljnje degradacije staništa izvorišnog dijela rijeke Dobre trebala bi biti jedan od prioriteta lokalne uprave

Fauna tulara (Insecta: Trichoptera) Parka prirode Papuk, Hrvatska.

Adult caddisflies were collected in early summer and autumn in 2012 at various freshwater habitats within Papuk Nature Park. Caddisflies were collected using sweep nets and light traps at eight sampling sites. A total of 360 individuals belonging to 33 species, 24 genera and 11 families were recorded during the current study. A preliminary list of caddisfly species occurring in Papuk Nature Park is presented. Seven species collected are the first records for the caddisfly fauna of Croatia: Rhyacophila loxias, Rhyacophila nubila, Rhyacophila obliterata, Rhyacophila polonica, Wormaldia pulla, Diplectrona atra and Drusus schmidi. Some of these species were also hitherto not recorded within the ecoregion Hungarian lowlands (ER11). Additionally, the rare Beraea maurus was recorded for the first time in Croatia after the single finding in 1934.Odrasli tulari prikupljani su u rano ljeto i jesen 2012. godine na različitim slatkovodnim staništima u Parku prirode Papuk. Istraživanjem je obuhvaćeno osam različitih postaja, a prikupljanje je provedeno uz pomoć entomoloških mrežica i svjetlosnih klopki. Ukupno je prikupljeno 360 jedinki iz 33 vrste, 24 roda i 11 porodica tulara. U radu je prikazan preliminarni popis faune tulara Parka prirode Papuk. Sedam vrsta zabilježenih u ovom istraživanju novo je za faunu Hrvatske: Rhyacophila loxias, Rhyacophila nubila, Rhyacophila obliterata, Rhyacophila polonica, Wormaldia pulla, Diplectrona atra i Drusus schmidi. Osim toga, neke od tih vrsta do sada nisu bile zabilježene niti u panonskoj limnoregiji (ekoregija ER11). Nadalje, zanimljiv je i nalaz rijetke vrste Beraea maurus koja je u Hrvatskoj do sada zabilježena samo s jednim primjerkom 1934. godine
