Abstract

The third report of the Croatian Rarities Committee presents 123 records of rare birds accepted in the period of 2005-2012. Eleven species and one subspecies were added to the list of Croatian birds, giving the total number of 389 bird species recorded in Croatia in categories A to C. A further 11 species were recorded in category D and two in category E. Four species are removed from the rare birds list because of the increasing number of observations. The list of rare bird species now includes 61 species and three subspecies, of which nine species are included in category D (possible escapees) and two in category E (escapees).

Abstract

Despite the story of the Poreč Botanic Garden being constantly featured in local monographs, books and in the lore of the local people, the history and circumstances that led to the establishment and decline of the Poreč Botanical Garden were never completely clarified. The aim of this research was to find records of its existence, determine the place and time of its origin, identify the persons responsible and explain the circumstances threatening the loss of the last remains of the garden. The result have shown that Poreč had a botanical garden a century ago, and point out the urgent need for its preservation and restoration.

Abstract

According to „Target 8” of Global Strategy for Plant Conservation (GSPC, 2011-2020), at least 75% of threatened plant species must be preserved in ex situ garden-collections, preferably in the countries of their origin, until 2020. The aim of the present study was to examine the list of Croatian threatened and statutorily protected plant species in ex situ conservation of the Botanical Garden (Faculty of Science, University of Zagreb). Out of 668 indigenous taxa of the Garden’s native-plant collections, we found 208 strictly protected and protected species, which is 12.7% of all statutorily protected taxa in Croatia. In the categories RE, CR, EN and VU there are 31 species, constituting 13.1% of threatened taxa in Croatia in those categories. In all categories, we found 80 taxa listed in the Red Book of Vascular flora of Croatia, 24 taxa are identified in the European Red List of Vascular Plants, while 12 taxa are found in the IUCN-Red List of Threatened Species in the World. Serious efforts are yet to be made in ex situ conservation of Croatian threatened species, in order to achieve the goals of „Target 8”.

Abstract

Epiphytic diatoms on Nymphaea alba L. floating leaves during plant growing seasons in the oligotrophic Sub-Mediterranean wetland Hutovo Blato, South Bosnia and Herzegovina, were investigated in 2003 and 2004. In total, 135 taxa (species and infraspecific taxa) of epiphytic diatoms were identified. Genera with the largest number of taxa were: Eunotia (14), Gomphonema (13), Cymbella and Navicula (9), Cyclotella (6), Diatoma and Nitzschia (5). Only three taxa were recorded in all samples: Brebissonia lanceolata, Eunotia arcus and Navicula radiosa. The most abundant taxa were Cocconeis placentula, Cyclotella comta, Eunotia arcus and Gomphonema longiceps.

Abstract

A floristic study of Jarun Recreational and Sports Centre in Zagreb was conducted during the vegetation season of 2006 and partially in 2008. In total, 323 plant taxa from 70 families are presented in the list, out of which 156 are newly found, while the presence of 49 previously reported taxa was not confirmed. The most abundant family is Poaceae (11.76%), followed by Asteraceae (9.94%), Fabaceae (6.81%) and Lamiaceae (6.81%). The life form spectrum shows that hemicryptophytes are the most common life form (42.41%), followed by therophytes (24.77%). The phytogeographical spectrum shows the strong prevalence of Euro-Asiatic plants (44.10%), and a high number of adventive (9.94%) and Mediterranean plants (9.63%), while the Illyrian-Balkan chorotype is almost absent (0.31%). Only six taxa are found on the National Red List (Ophrys apifera, Alopecurus geniculatus, Carex panicea, Cyperus fuscus, Orchis militaris and Orchis tridentata), while 25 taxa are classified as invasive. Finally, we conclude that the flora of Jarun is greatly anthropogenically influenced, but still relatively rich.

Abstract

We monitored the breeding success of the Common Cuckoo (Cuculus canorus) in four reed habitats (e. g. clay pits, marsh and fishponds, small canals and large canals) in northwestern Vojvodina (Serbia) between 2009 and 2011 (three breeding seasons). A total of 596 Great Reed Warbler (Acrocephalus arundinaceus) nests were found and monitored. The overall parasitism rate for the study area was 0.127, which was calculated from the number of parasitized nests (76) divided by the total number of Great Reed Warbler nests (596). The parasitism rate did not vary with the total number of Great Reed Warbler nests at a study site. The number of parasitized and successful parasitized nests showed significant negative relationship, which means more parasitized nests resulted with more brood lost. The parasitism rate varied significantly among habitats but not among years while the number of successfully parasitized nests differed among both habitats and years. Parasitized nests found in small and large canals showed the highest reproductive success of Cuckoos. Loss of parasitized nests through predation and bad weather circumstances was relatively high in this study compared to other areas.

Abstract

Entomologists have researched into the butterflies of Zagreb City with different levels of intensity since the beginning of the 20th century and recorded a great number of species. Many butterfly sites historically surveyed are now completely changed or have completely disappeared due to the expansion of the city and changes in habitat management. Our research was conducted between March 2009 and September 2010 in the Vugrovec area, located at the northeastern edge of the city. Vugrovec is still a rural area, but the city itself is fast approaching, and will probably be merged in the near future. So this area could be considered similar to the historically studied sites in the former rural areas nowadays urbanized. A total of 88 butterfly species were identified, which accounted for 45% of Croatian butterfly fauna. Ten recorded species are endangered and listed in the Red data list of Croatian Butterflies: Lycaena dispar (NT), Glaucopsyche alexis (NT), Pseudophilotes vicrama (NT), Scolitantides orion (NT), Phengaris arion (VU), Papilio machaon (NT), Pieris brassicae (DD), Polyommatus thersites (NT), Apatura ilia (NT), and Heteropterus morpheus (NT).

Abstract

Peatlands in Croatia are rare, small in size and isolated habitats. Due to the abandonment of traditional land-management practices, and particularly to the progressive vegetation succession, they are critically endangered. Caddisfl y faunistics and ecology of peatlands in Croatia have never been studied. A total of seven caddisfl y taxa were collected in this study at three diff erent peatlands; Dubravica bog, Đon močvar bog and Jarak fen. The collection of Adicella reducta (McLachlan, 1865) represents a new record for the Croatian caddisfl y fauna. Additionally, two tyrphophilous species, Hagenella clathrata (Kolenati, 1848) and Rhadicoleptus alpestris (Kolenati, 1848), were recorded for the fi rst time in Croatia since an imprecise literature record from 1935 and two previous fi ndings (from 1929 and 1997), respectively. Caddisfl y 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.

Abstract

Results of a malacological survey of the Korana River are presented. The molluscan assemblages of this karstic river between its outflow from Plitvice Lakes and the inflow to the Kupa River at Karlovac were studied from 2009 to 2012. Altogether 33 aquatic molluscs (21 gastropods, 12 bivalves) were found at 13 sites. Theodoxus danubialis, Esperiana esperi, Microcolpia daudebartii, Holandriana holandrii and Bithynia tentaculata were dominant at most of the sites. A population of the endangered thick-shelled river mussel Unio crassus was recorded. The occurrence of three non-native molluscs (Physella acuta, Ferrissia fragilis, Sinanodonta woodiana) was documented. The results of this research were compared with those of previous investigations and also with those for molluscan assemblages of the adjacent part of the Kupa River.
