Vlažna staništa pružaju mnoge usluge ekosustava, npr. služe kao prirodne retencije poplavnih voda, a mogu biti i područja za rekreaciju šire javnosti. Predstavljaju i životno važna staništa za brojne ...životinjske vrste, stoga su mnoga vlažna staništa pod nekim stupnjem zaštite. Unatoč tomu, fauna mnogih vlažnih staništa i dalje je većinom nepoznata, posebice po pitanju kornjaša. Nepoznavanje faune određenog područja otežava upravljanje istim. Jedna takva lokacija je šuma Turopoljski lug, smještena jugoistočno od glavnog grada Zagreba. Terensko istraživanje provedeno je od ožujka do rujna 2017. Koristile su se četiri metode: kečiranje, zamke s mamcima na stablima, svjetlosne zamke s UV žaruljama po noći i sakupljanje rukom. Rezultatima je pridodano i nekoliko nalaza od ranije. Ukupan broj poznatih vrsta kornjaša za Turopoljski lug podignut je s 51 na 133. Devet vrsta imaju gotovo ugrožen IUCN status ugroženosti, od kojih je sedam saproksilnog načina života. Iz područja su poznate tri vrste navedene u Dodacima II i IV Direktive o staništima, od kojih smo zabilježili samo
Cerambyx cerdo
. Također, pronađen je zanemaren nalaz iz literature za četvrtu –
Phryganophilus ruficollis
. Potrebno je preispitati i, po potrebi, izmijeniti dosadašnji način upravljanja šumom. Buduća usmjerena istraživanja određenih skupina kornjaša trebala bi uroditi dodatnim povećanjem broja vrsta poznatih za lug, dok bi ciljano kartiranje prisutnosti vrsta s Dodataka iznjedrilo prijeko potrebne podatke za zaštitu prirode.
Wetlands provide many important ecosystem services, e.g. serving as natural retention areas to prevent flooding and they can be recreational areas for the general public. They also represent vital habitats for many animal species and many are protected nature areas. In spite of this, the fauna of many wetlands in Croatia is still mostly unknown, especially when it comes to beetles. Not knowing the fauna of a particular habitat hinders management efforts. One such location is Turopoljski Lug forest, south-east from the capital Zagreb. The fieldwork was done from March till September 2017, utilising four methods: sweep netting, baited traps on tree trunks, light trapping with UV light traps at night, and collecting by hand. Additionally, several records from earlier visits are included. The total number of currently known species for the forest is raised from 51 to 133. A total of nine species are near threatened (NT), seven of which are saproxylic. Three species listed in Annexes II and IV of the Habitats Directive occur in the area, of which only
Cerambyx cerdo
had been recorded
.
Additionally, a neglected literature record of a fourth,
Phryganophilus ruficollis
, has been discovered. Current management practices for the forest should be re-evaluated and modified if necessary. Future research targeting specific beetle groups should yield further increases in the number of species known for the area, while a targeted mapping of the distribution of species listed on the Annexes should yield much-needed conservation information.
Background and purpose: The moth fauna of Croatia is still insufficiently surveyed. During the last several years, several overviews of the moth fauna for several locations were published and several ...new species for the country had been found. Only two species from Annexes II and IV of the Habitats Directive are listed for Croatia. A third is known to occur in the country, but has been omitted due to a lack of recent records. Presented here is the first record of a fourth species from the Annexes – Arytrura musculus.Materials and methods: This survey was carried out on one location in Nature Park Lonjsko Polje, on 17.6.2016. The habitat at the location is typical for the area, consisting of floodplain oak forests with Genista tinctoria. Two pyramidal light traps were used.Results: One specimen of Arytrura musculus was found. This is a rare and disjunctly distributed species across Eastern Europe. The closest known populations to the Croatian locality are situated in Hungary, 122 and 130 km away.Conclusions: This species needs to be added onto the list of Natura 2000 species for the Nature Park and for the whole country at the earliest possible convenience. Detailed surveys of the entire Lonjsko Polje Nature Park and other wetland areas in northern Croatia are needed in order to ascertain the distribution, assess the status and assure the long-term conservation of this species in the country.
The pond slider Trachemy scripta was one of the most commonly exported turtles until the last decade and often released into the wild outside its native range. It was introduced to Europe, Africa, ...South America and Asia and included on the EU list of 100 World's Worst Invasive Alien Species and the List of invasive alien species of Union concern. The import of the subspecies Trachemys scripta elegans into Europe and Croatia has been banned for some time, but the number of specimens recorded in nature is still increasing. In this paper we present 45 new localities were the species was observed in Croatia, which makes a total of 84 known localities. Most of the records, 58%, are in the Continental biogeographical region and the rest in the Mediterranean. It has not yet been recorded for the Alpine biogeographical region. Most records (42%) come from ponds. Three new sightings of females digging nests, laying eggs and sightings of hatchlings were recorded, suggesting successful reproduction of the species. Further surveys of this alien species in Croatia are needed.
Entomological collections are an invaluable source of data, due to the variety of species they contain, capturing the biodiversity of a given time. Thus, the entomology part of the Division of ...Zoology Collection (Faculty of Science, Department of Biology), in Zagreb, established in 1890, is an important asset for all faunistic research and any overview of historical changes in species composition, as well as an important resource in the education of young scientists. Here we provide records of 198 ladybird specimens belonging to five tribes and 24 taxa. Coccinella septempunctata Linnaeus, 1758 and Hippodamia (Hemisphaerica) tredecimpunctata (Linnaeus, 1758) were the most abundant species in the collection, with 59 and 40 specimens respectively. The altitudinal range for the specimens in the collection is 10–1031 m a.s.l., with most records having been found between 10 and 199 m a.s.l. Due to the educational and scientific importance of entomological collections, it is recommended that the review and inventory of the entomological material within the Division of Zoology Collection be continued.
Predstavljeni su nalazi riđovke Vipera berus bosniensis (Boettger, 1889) iz jednog zagrebačkog “otoka prirode”, što dokazuje da ova vrsta nije nestala na području grada Zagreba. Raspravlja se o ...važnosti i implikacijama ovog nalaza svojte koja ima status gotovo ugrožene vrste (NT) u Hrvatskoj.
