Here we present the results of a mayfly study conducted on a hydromorphologically altered lowland river in Croatia, the Bednja River. 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.

The flora of three small islets located in the Korčula Archipelago was investigated on several occasions during 2020. 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.

Alpiscorpius liburnicus sp. n. is described from Krk Island, Croatia, as the first cave dwelling scorpion species in the genus. 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.

In this paper, we report two new locations of the alien invasive seed beetle Megabruchidius dorsalis in Zagreb, Croatia. Additionally, we confirm for the second time the presence of M. dorsalis at one location in the same city. All beetles were reared from mature Gleditsia triacanthos pods collected from the ground (three locations) and from trees (one location). These records contribute to the knowledge of the distribution of M. dorsalis in Europe.

The European snake-eyed skink (Ablepharus kitaibelii) is an endangered lizard species in Croatia, limited to a very small area in Papuk Nature Park, and several localities in the town of Ilok and the surrounding area. On Mt Papuk, the species is limited to an area of the warm southern slopes of the Turjak-Mališćak-Pliš peaks, above Velika. In the year 2019, the species was documented in a new location, on Stinice. The aim of this study is to analyse morphometric measures, relative density, predatory pressure, and to determine the sustainability of this population. Data obtained were compared with the previous research into the European snake-eyed skink on Turjak, the most researched European snake-eyed skink site on Papuk so far. The population on Stinice has lower density, and is under higher predatory pressure than the population on Turjak. Also, there are differences in some morphometric measures between these two populations that should be further explored.

Artemia cf. parthenogenetica Bowen and Sterling, 1978 is widely distributed in the saline lakes of Northern Kazakhstan. 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.
单性生殖蒿(Artemia cf. parthenogenetica Bowen and Sterling, 1978)广泛分布于哈萨克斯坦北部的盐湖。在释放之前，雌性阿尔忒弥斯很容易被一个充满囊肿的育儿袋认出。囊肿的数量可以用来估计个体的繁殖能力和整个种群。在对Artemia生殖性能的研究中，观察到在整个生长季节，水体中有发育良好的雌虫，其育苗袋部分充满了囊肿。因此，我们面临着一个问题，即使用部分填充育儿袋的雌性来确定Artemia的生殖性能。在满育袋和半满育袋中，囊泡数在平均繁殖性能、变异系数、平均最小和最大繁殖性能等统计指标上表现出一致的差异。随着种群中囊肿尚未准备释放的雌性百分比的增加，部分填充育儿袋的雌性百分比减少。综上所述，使用部分填充育儿袋的雌性，低估了平均繁殖性能的有效值，也改变了繁殖性能的分布模式。所得结果证明，在评估青蒿的生殖性能价值时，只应使用育儿袋满的雌性。

The aim of this study was to investigate for the first time some aspects of the reproductive activity of the Caramote prawn, Melicertus kerathurus, in Montenegrin waters. This species is considered a target species in the small-scale fishery in Boka Kotorska Bay, being a species of high commercial value. Sampling was carried out on a monthly basis from April 2019 to December 2019 by trammel nets. The spawning season was estimated based on monthly changes in the gonadosomatic index, condition factor and gonadal maturity stages. The main spawning season for females extends from April-May to September, with a clear peak in June. The total sex ratio (males/females) was 1:1. Sexual differences related to the length-weight relationship were noted.

In August 2022 the first individuals of the dragonfly species Violet dropwing, Trithemis annulata (Palisot de Beauvois, 1807), were observed in Croatia, at three localities in southern Dalmatia. Two males were observed at the Peračko Blato lake, while both males and females were recorded at two localities at the Baćinska Lakes. At the Baćinska Lakes, more than 10 individuals were observed indicating a possible established population. The nearest known reproducing population is located about 160 km to the south, in Montenegro. Due to the species expansion in Europe, and recent records as north as Slovenia, additional records and established populations are to be expected in Croatia. As the species is now known from Croatia, we propose a vernacular name for this species, “ljubičasta skitnica” meaning purple tramp, referring to its coloration, wandering behavior and dispersal potential.
2022年8月，在克罗地亚达尔马提亚南部的三个地方观察到了紫罗兰垂翼蜻蜓的第一个个体，环纹蜻蜓（Palisot de Beauvois，1807）。在Peračko Blato湖观察到两只雄性，而在Baćinska湖的两个地方记录到雄性和雌性。在Baćinska湖，观察到10多人，表明可能有一个已确定的种群。已知最近的繁殖种群位于黑山以南约160公里处。由于物种在欧洲的扩张，以及最近北至斯洛文尼亚的记录，预计克罗地亚将有更多的记录和已建立的种群。由于该物种现在在克罗地亚为人所知，我们为该物种提出了一个当地名称，“ljubičasta skitnica”，意思是紫色流浪汉，指的是它的颜色、流浪行为和扩散潜力。
