Abstract:
This study of mosquitoes in Lika, geographically, geologically and climatically a very specific region, was conducted to gain insight into the composition and relative abundance of the mosquito fauna, as well as to check for the possible presence of invasive species. Sampling took place from July to September 2020. Mosquito larvae were captured from medium and small breeding sites using a 25 cm diameter net and a plastic dipper. Adult specimens were sampled in both urban and rural areas using CO2 baited CDC traps, CO2 baited BG Sentinel traps with BG Lure and human landing catch. The study was conducted at 69 sites. We collected 5,126 specimens (100 adults and 5,026 larvae) and demonstrated the presence of 16 mosquito species. CDC traps were almost five times more effective (quantity and quality) than BG Sentinel traps. The most common mosquito taxa caught in Lika were Culex pipiens complex (78.36% of all larvae) and Ae. geniculatus (30.26% of all adults). Both invasive mosquito species present in Croatia, Aedes albopictus and Ae. japonicus, were recorded, with Ae. albopictus being detected in Lika for the first time. Aedes japonicus was widespread, recorded in 23 localities. According to molecular analysis, only An. maculipennis s.s. was confirmed in the An. maculipennis complex. Within the Cx. pipiens complex, both Cx. pipiens biotypes, pipiens and molestus were confirmed together with one single hybrid specimen. Analysis of mosquito occurrence with regard to altitude shows that most samples and species were collected between 601 and 700 m a.s.l., although the Shannon evenness index and Hill’s index show the highest value in the range of 901 to 1140 m a.s.l. In this systematic study on the mosquito fauna in Lika, a significant species diversity, including invasive species, was found.

Abstract:
We report on and discuss records of five species new to the vascular flora of Croatia. Calamagrostis canescens was found near Đurđevac in remnants of fen vegetation, and we consider it a critically endangered species in the flora of Croatia. Agrimonia procera is native or archaeophyte in central Croatia and its discovery is in accordance with its earlier use as a medicinal plant. Amaranthus emarginatus is an exotic newcomer that was previously found in urban habitats on the north Adriatic coast. Carex vulpinoidea and Oenothera suaveolens were shown to be locally established species, in meadows along the Kupa River, and on the bars of the Drava River, respectively. In addition, we present new distributional and ecological data on two neophytes (Cardamine occulta, Humulus scandens) that were only briefly mentioned in earlier sources from Croatia.

Abstract:
From 2016 to 2020 numerous surveys were undertaken to improve the knowledge of the pyraloid moth fauna of Biokovo Nature Park. On August 27th, 2020 one specimen of Psorosa mediterranella (Amsel, 1954) from the family Pyralidae was collected on a small meadow (985 m a.s.l.) on Mt Biokovo. In this paper, the first data about the occurrence of this species in Croatia are presented. The previous mention in the literature for Croatia was considered to be a misidentification of the past and has thus not been included in the checklist of Croatian pyraloid moth species. P. mediterranella was recorded for the first time in Croatia in recent investigations and, after other additions to the checklist have been counted, is the 396th species in the Croatian pyraloid moth fauna. An overview of the overall pyraloid moth fauna of Croatia is given in the updated species list.

Abstract:
Two new ultraspecialized troglomorphic Leptodirini (Coleoptera, Leiodidae, Cholevinae) from two Croatian caves are described. Hygrodromus (new genus) nikolinae, a new species from Mladenova cave near Orebić, is a very enigmatic taxon of “tetramerous”Leptodirini, markedly distinct for several morphological features in antennae, mouthparts, male genitalia and the peculiar sexually dimorphic apex of elytra. However, because of some characters, it could be assigned to the phyletic lineage of Hadesia and Nauticiella, which so far includes only “pentamerous”species. Leptomeson vuicae from Dragina lipa jama cave near Čelopek in central Dalmatia, owing to its morphological features, is the south-eastern substitutive adelphotaxon of L. dombrowskii, from which it differs by its smaller size, longer elytral pubescence and the different shape of the median lobe of the aedeagus with a stouter apex.

Abstract:
Here we present a first record of Baetis vardarensis Ikonomov, 1962 in Croatian freshwater habitats. The species was collected in February and March 2020 at two sites in the Sava River. With this record, Croatian mayfly species richness increased to a total of 85 species. In addition, one of the species previously known only from literature, Kageronia fuscogrisea (Retzius, 1783), was confirmed in Croatia. The species was collected in the Rečica River, in March 2020. These results confirm that our knowledge about mayfly fauna in different regions of Balkan Peninsula is still incomplete and is increasing with systematic studies.

Abstract:
The plant lists of Gladiolus, Crocus and other members of the Iridaceae family grown in the Botanical Garden from 1895 to 2021 are studied, with a supplement for the genus Iris, analyzed in 2019. The nomenclature, synonymy and origin of plant material were arranged. Lists of species grown in the last 126 years are constructed to show that throughout that period at least 448 taxa of wild and cultivated Iridaceae from 30 genera inhabited the Garden’s collections. Today we have 371 taxa out of 21 genera. Out of this number, the genus Gladiolus accounts for 35 taxa (formerly 50), Crocus 7 (formerly 27), while Iris includes as many as 291 species, cultivars and hybrids. The remaining 18 Iridaceae genera are represented by 38 taxa.

Abstract:
The carpological collection of Professor Ivo Horvat, a famous Croatian botanist of 20th century, was saved from oblivion, after its unexpected discovery at the Faculty of Veterinary Medicine in Zagreb in 2019. As many as 515 diaspores (fruits and seeds) of 486 vascular plant taxa were systematised and digitised and the nomenclature was updated. A comprehensive comparison of Horvat’s carpological and herbarium collection (ZAHO) revealed a large amount of overlap. A large photo-catalogue was created and will be publicly accessible through the Flora Croatica Database.

Abstract:
This paper aims to present the diversity of endemic plants in the Shutman area and an analysis of chorological groups and life forms. The flora of Shutman comprises 31 endemic plant species. Among them, there are 20 Balkan endemics, 1 stenoendemic and 5 sub-endemic species. They belong to 20 genera and 13 families. The richest among the endemics are families Asteraceae and Caryophyllaceae, both with 4 species. All endemics are herbaceous perennials. Hemicryptophytes dominate among life forms, accounting for 58.06%. Most of the species are Balkan floristic elements (20 species or 64.52%), followed by Southeast European and South European floristic elements, both with 3 taxa (9.68%). A total of 27 species have national or international conservation status. Reporting of Ranunculus degenii Kümmerle & Jav. for the first time in Shutman makes this area the second distribution record of this plant in Kosovo.

Abstract:
In spring 2021, four unusual encounters with a group of false killer whales were recorded in Kvarner Bay, Northern Adriatic Sea. A minimum of five individuals, including a calf, were observed and two photos were taken corroborating species identification. These are the first reported sightings of the species in the Adriatic Sea since the mid-twentieth century. In addition, another encounter was revealed that occurred at the end of the 2000s in the same location and should be added to the list of historic observations. These reports were obtained by chance and show the importance of citizen science in obtaining data on rare marine species. The information gathered goes towards a better understanding of the distribution of the species in the Mediterranean Sea.

Abstract:
The aim of this paper is to make a comparative analysis of benthic macroinvertebrate compositions in streams and rivers in Croatia with relation to different physical-chemical factors, especially nutrients. Samples were collected according to the AQEM method. At all the sites, 20 taxa were recorded of which Turbellaria, Gastropoda, Bivalvia, Oligochaeta, Hirudinea, Crustacea, Ephemeroptera, Odonata, Plecoptera, Heteroptera, Trichoptera, Coleoptera and Diptera were included in the present study. Water temperature mostly affected the composition of benthic macroinvertebrates to which it was inversely proportional. Nutrient enrichment, i.e., higher concentrations of ammonium, nitrates, nitrites, total nitrogen, orthophosphates and total phosphorus mostly affected Ephemeroptera, Plecoptera, Trichoptera and Diptera, by decreasing their diversity.
