Abstract
^ingi-Lingi Lake is a gravel pit produced 25 years ago. During investigation of zooplankton in the year 2004 we determined eight species. Three of them are copepods and five of them are cladocerans. ^ingi-Lingi Lake is the only locality where zooplankton in the Drava Valley region has been investigated.

Abstract
A Northern Wall Brown Lasiommata petropolitana (Fabricius, 1787) was found in a closed beech forest beside the mountain trail heading from Mt. Platak to Mt. Snje`nik in June 2003. We discuss the ecological characteristics and distribution of this species in Croatia. We are including the Northern Wall Brown as 192nd species on the checklist of butterflies of Croatia.

Abstract
Natural science collections can be estimated for their scientific, cultural and financial values. How should the scientific value of a biological collection be assessed? That the specimens last and are in good condition is more necessary for any collection than any quantification of its value. The total number of specimens and the total number of species in biological collections do not tell us anything about the value of individual specimens in the collection and they are hardly comparable among collections of different taxa. The basic purpose of biological collections is to be a source of data for biological research. Therefore, the amount and quality of scientific publications based on specimens from a particular collection could be a good guide to the value of the collection in question, and, in most cases, a good indication of its total value.

Abstract
Epilobium (s. lat.) herbarium material in two major Croatian herbaria ZA and ZAHO was revised. The results of the revision of over 400 herbarium sheets confirmed the occurrence of 13 species already reported for Croatia and only slightly changed their known distribution patterns. However two species previously reported for Croatia and represented also by some herbarium sheets turned out to be wrongly determined, the results being that there is now no reliable confirmation of E. alsinifolium and E. alpestre from the territory of Croatia. Summarized results of the revision are also presented and they demonstrate the comparably good level of correctly determined material in the studied herbaria (but with some taxa much less reliably determined) and an alarmingly low state of collecting activity in the last decades.

Abstract
As a part of the study of Medvednica Nature Park flora, the distribution of the grass taxa has been studied. The floristic mapping resulted in the establishment of 100 grass taxa from 47 genera. The species Brachypodium sylvaticum was found to be the most widespread grass species in the Nature Park area. Twenty one species were recorded in one MTB 1/64 quadrant alone. The data on 31 taxa originate from earlier periods and their occurrence was not confirmed in the recent research. Grasses from Mount Medvednica can be assigned to 10 floral elements. Thirty five grasses which could be defined as ruderal, cultivated or weeds were found in Medvednica Nature Park. According to the Red Book of Vascular Flora of Croatia 14 species are threatened to some degree.

Abstract
A small collection of Trichoptera, collected by Franjo Ko{}ec and stored in the Municipal Museum Vara`din, Croatia, is listed. The specimens were collected in the surroundings of this town, mainly in the period of 1927–1934. Two specimens of the remarkable species Platyphylax frauenfeldi, collected in 1940, are included.

Abstract
In this paper we examine the distribution of amphibians and reptiles over the islands of the newly founded Lastovo Archipelago Nature Park (Lastovsko oto~je), Croatia. On several field trips between 1996 and 2008, we encountered five species of lizards (Podarcis sicula, P. melisellensis, Dalmatolacerta oxycephala, Hemidactylus turcicus and Pseudopus apodus), one species of snake (Dolichophis caspius), one species of sea turtle (Caretta caretta) and one species of toad (Bufo viridis). We confirm literature data on the presence of some of these species on different islands of the archipelago, and add distributional records for several other islands and islets. Logistic regression analyses show that the variables predicting presence/absence from different islands vary among species. Within species, populations from different islands noticeably vary in body size and shape, scalation, dorsal and ventral coloration, behaviour and density. This observation adds to the value of the study area as a »natural laboratory« for future research into the ecology and evolution of island populations. Although most species seem to be doing well presently, we list a number of possible hazards and concerns.

Abstract
The paper gives information on new finding sites of the terrestrial snails Pupilla triplicata (S. Studer, 1820), Medora dalmatina aquila (L. Pfeiffer, 1846), Paralaoma servilis (Shuttleworth, 1852), Daudebardia rufa rufa (Draparnaud, 1805), Caracollina lenticula (Michaud, 1831) and Xerotricha conspurcata (Draparnaud, 1831), which are rarely recorded for the fauna of Croatia. The new finds are on the islands of Vis, Bi{evo, Brusnik, Svetac, Palagru`a and Mala Palagru`a, which constitute parts of central and southern Dalmatia (Croatia).

Abstract
The known geographical distribution of the stonefly species Protonemura julia Nicolai, 1983 (Nemouridae, Amphinemurinae) has been considerably extended with new records from Croatia. For the first time, this so-called endemic species of the Italian Julian Alps was found in the mountainous region Gorski kotar (north-western Croatia), at ^abranka River spring area in summer 2006. The first record of the species was reconfirmed on the next field trip in autumn 2006, and it was additionally found at Gerov~ica Stream spring area. The new records reported here are the southernmost findings of P. julia, confirming indications that some springs in the Gorski kotar area serve as microrefugia for cold stenothermic species.

Abstract
Benthic invertebrate communities of the Cetina River and the upper reach of the Ruda River were sampled monthly at 11 sites from August 2004 to August 2005. The sampling sites were located along the longitudinal gradient of the Cetina and in the upper reach of the Cetina's largest tributary, the Ruda River. Throughout the study, a total of 310225 animals were collected in 366 samples. In the upper and middle reaches the most numerous taxa were Amphipoda and Gastropoda, while the most numerous taxon in the lower reaches was Gastropoda. The highest and the lowest population density of benthic invertebrates were recorded at the sites Preo~ki Most in June 2005 (22728 individuals/m2) and Radmanove Mlinice in November 2004 (90 individuals/m2), respecti- * Note: surname of authors in alphabetical order, except first and corresponding author Croatian Natural History Museum, Demetrova 1, Zagreb, Croatia M:NATURAnatura_1-09vuckovic.vp 24. lipanj 2009 10:20:47 Color profile: Disabled Composite 150 lpi at 45 degrees 50 Vu~kovi}, I. et al.: Benthic macroinvertebrate communities in the Mediterranean karst river the Cetina... vely.

Abstract
The present paper deals with the distribution of Araneus alsine (Walckenaer, 1802) (syn.: Epeira alsine Walckenaer, 1805; E. lutea C. L. Koch, 1837) in Croatia and its habitats based on literature data, museum collections and field findings. The spider A. alsine was captured in Croatia’s most diverse and oldest peatland, the on Mo~var Botanical Reserve at Blatu{a. The biology, ecology and threat status of A. alsine are discussed.

Abstract
In this paper 5 species of cave-dwelling spiders of the genus Troglohyphantes are listed as new for the Croatian fauna. They are T. troglodytes (Kulczyñski, 1914), T. pugnax Deeleman-Reinhold, 1978, T. salax (Kulczyñski, 1914), T. sketi Deeleman-Reinhold, 1978 and T. subalpinus Thaler, 1967. All five species are known from neighboring countries. New localities are marked on the map and the ecological status is given for every species. With these five species the total number of Troglohyphantes taxa in Croatia has risen to 22 taxa.

Abstract
The cave leptodirine beetle species of the genus Blattochaeta lives mainly in caves at higher altitudes of Montenegro and on the Herzegovinian side of Orjen Mountain. Previously, 5 species and 3 subspecies of this genus were known. In the present paper a new subspecies from Glogova jama [pit] in Mt Snije`nica in Croatia is described. The new subspecies is the smallest subspecies of Blattochaeta marianii, a species that lives in the wider Orjen plateau on the border of Montenegro, Bosnia and Herzegovina and Croatia.
