Twenty-two mayfly species were recorded, Baetis fuscatus (Linnaeus, 1761) and Serratella ignita (Poda, 1761) being the most widespread and Paraleptophlebia submarginata (Stephens, 1836) and Cloeon dipterum (Linnaeus, 1761) the rarest species. A significant increase in mayfly species richness was observed along the river course. Nevertheless, cluster analysis showed that their assemblages were not grouped according to the study position along the Bednja River. The lowest species richness and diversity were recorded for the spring area. Surprisingly, the highest species richness was found at a site with moderate hydromorphological alterations, and the highest diversity at a site with severe hydromorphological alterations. This could be because the river is connected to numerous lateral streams and a variety of microhabitats are available. New distribution records in Croatia are presented for some rare species in Croatian freshwater habitats, such as Heptagenia longicauda (Stephens, 1836). Ephemera lineata Eaton, 1870 was recorded for the first time in the Pannonian lowland ecoregion (ER 11) in Croatia. Caenis cf. pseudorivulorum Keffermüller, 1960 has not yet been recorded in Croatian freshwater habitats, but since our identifications are based on juvenile specimens, its occurrence is still to be confirmed.","PeriodicalId":36013,"journal":{"name":"Natura Croatica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47742486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In all, 105 plant taxa were recorded, of which 101 are angiosperms, 3 gymnosperms and with 1 fern. The total flora of the islets is distributed in 48 families. The families with the highest number of taxa are Poaceae (12.38%) and Asteraceae (10.48%), followed by Lamiaceae (7.62%) and Fabaceae (5.71%). The most common life forms are therophytes (31.43%), hemicryptophytes (27.62%) and phanerophytes (19.05%). The largest number of plant taxa is accounted for by the Mediterranean floral element (60.95%), followed by the South European (20.00%) In all, three endemic, four endangered and seven strictly protected taxa were recorded. Endemics are Carduus micropterus (Borbás) Teyber ssp. micropterus, Vincetoxicum hirundinaria Medik. ssp. adriaticum (Beck) Markgr and Limonium dictyophorum (Tausch) Degen. All recorded endemic taxa belong to the group Illyrian-Adriatic endemic plants. Endangered taxa are Desmazeria marina (L.) Druce, Elymus pycnathus (Godr.) Melderis and Narcissus tazetta L. Strictly protected taxa include Chenopodium murale L. and Posidonia oceanica (L.) Delile. The invasive species Conyza canadensis (L.) Cronquist and Euphorbia prostrata Aiton have been recorded in the flora of the islet of Majsan.","PeriodicalId":36013,"journal":{"name":"Natura Croatica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48131007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clear differences from the genetically closest epigean species were found in metasomal morphometry. Its delineation is supported phylogenetically based on mitochondrial (COI and 16S rRNA) and nuclear (ITS1) markers. In the barcode fragment of the mitochondrial cytochrome oxidase subunit 1 gene (COI), the uncorrected pairwise genetic distances to other known taxa in “Alpiscorpius croaticus group” range between 4.2 and 4.8 %. The first molecular evidence of the species’ presence on the coastal part of Mt. Velebit implies its potential distribution in the whole of the eastern Adriatic coastal area, roughly from Rijeka City area to the source of the Zrmanja River. The new species is sympatric with common epigean taxa of the “Euscorpius tergestinus group” and with the synanthropic E. italicus in Mediterranean habitats. The phylogenetic relationships within the “A. croaticus group” are estimated. Localities of epigean A. croaticus are restricted to the continental side of southern and southeastern parts of Mt. Velebit. There it is sympatric and syntopic with the smaller A. omega in karst beech forests, with an extrazonal enclave in the Velika Paklenica canyon area on the southern slopes of the mountain. The third taxon in the group is known at the moment from a single locality in the middle part of Mt. Velebit, where it is also syntopic with A. omega in a beech forest near limestone cliffs.","PeriodicalId":36013,"journal":{"name":"Natura Croatica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68196013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Female Artemia can easily be recognized by a brood pouch full of cysts before being released. The number of cysts can be used to estimate both individual reproductive performance and the entire population. During the studies involving Artemia reproductive performance, it was observed that throughout the growing season, in the water bodies, there were females whose well-developed brood pouches were partially filled with cysts. Thus, we were confronted with a question about the relevance of using females with partially filled brood pouches to determine the reproductive performance of Artemia. The number of cysts in a full brood pouch and a partially filled brood pouch revealed consistent differences in the following statistical indicators: average reproductive performance, coefficient of variation, and average minimum and maximum reproductive performance. As the percentage of females in the population with cysts not yet ready to be released increases, the percentage of females with partially filled brood pouches decreases. The general conclusion is that the use of females with partially filled brood pouches underestimates the valid value of average reproductive performance and also changes the pattern of the reproductive performance distribution. The obtained results prove that only females with a full brood pouch should be used when assessing the reproductive performance value of Artemia.","PeriodicalId":36013,"journal":{"name":"Natura Croatica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43903914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
