: Abnormal coloration shaped as small patches on a body or fins/tail flukes of cetaceans is relatively rare, although such cases have been recorded in multiple species. Several reports of anomalously colored dolphins and porpoises have been documented in the coastal waters of the Black Sea, with uneven distribution across the basin. Recently, during photoidentification (photo-ID) surveys conducted between 2022 and 2023, atypically pigmented bottlenose dolphin ( Tursiops truncatus ) individuals with white patches on their dorsal fins and bodies were spotted in Turkish territorial waters near Zonguldak Province. The analysis of photographs from these sightings offers a simple approach to detect and characterize different types of skin coloration of cetaceans inhabiting the south-western waters of the Black Sea.

: Plastic pollution has emerged as a prominent environmental concern over recent decades, particularly due to its critical implications for seafood safety. In light of this, an investigation was conducted to assess the abundance and characteristics of microplastics (MPs) in Unio mancus Lamarck 1819, a freshwater bivalve inhabiting Atatürk Dam Lake in Türkiye. For the MPs analysis, a total of 20 U. mancus Lamarck 1819 specimens were collected from the lake, with shell lengths ranging from 7.7 to 10.1 cm and soft tissue weights varying from 21.46 to 49.1 g. The findings of this study revealed the presence of MPs-like particles in 12 out of the 20 mussels, with a total count of 42 particles. MPs concentration ranged from 0 to 9.9 MPs per individual, with an average of 1.89 ± 0.57 MPs per individual. When considering the soft tissue weight, MPs concentration ranged from 0 to 50.51 MPs per 100 g, with a mean of 6.91 ± 2.56 MPs per 100 g. µ-Raman analysis further confirmed that 90% of the particles were composed of various polymers. Among these, polypropylene (PP) constituted 40%, polyethylene (PE) accounted for 20%, polyethylene terephthalate (PET) comprised 10%, Nylon-6 constituted 10%, and cellulose represented 10% of the identified particles. Notably, fragments were the predominant shape observed in the samples, and the majority of MPs were less than 100 µm in length. This study provides valuable foundational data for establishing frequent MP monitoring routines in freshwater environments, considering that bivalves serve as key vectors of MP contamination in the context of human exposure.

: Brown marmorated stink bug (BMSB), Halyomorpha halys , is a polyphagous invasive pest whose spread and damage are increasing with global commercial activities. In this study, following the invasion of Black Sea Region in 2018, spread, population density and change of the pest were investigated in the years 2019, 2020, and 2021, possible causes of spread and measures to be taken were evaluated. Course of population was monitored with pheromone traps placed in 141, 120, and 162 locations in 8 provinces along the coastline of Black Sea Region. High population density was detected at all locations of Artvin and Rize provinces. Since the population interactions continued near the Georgian border, about 98% of the total population in the region was seen in these two provinces. Weekly average population level was 7.36 adults/traps in Artvin and 9.11 adults/traps in Rize Province; spread of the pest continued from east to west and irregular and further-apart local populations were detected at some points. It was determined that it caused population density-dependent economic damage on different hosts including hazelnut, kiwi, citrus, maize and beans. This research examined the H. halys population distribution in Türkiye, potential problems associated to that too, ways that it spreads, and possible solutions.

: Installing an artificial nest box has a positive effect on the cavity nesters such as great tit ( Parus major ). Beyond the process of installing an artificial nest box, a study on the effect of ecological factors on breeding performance is necessary. This study was conducted to evaluate the ecological factors influencing breeding performance of great tits ( Parus major ) in artificial nest boxes in temperate mixed forests. In this study, the first egg-laying date and percentage of shrub were closely related among ecological factors. Variable influencing clutch size was date of first egg-laying date. Percentage of shrub had a positive relation to hatching success and fledgling success. First egg-laying date may represent quality of parental individuals. In addition, shrub can provide better food resources and has an impact on hatching success and fledgling success. These results suggest that higher quality of parental individual predominates the better the foraging site for enhancing breeding success. Also, managing shrubs in the forest appear to have a positive effect on breeding performance. Moreover, long-term ecological research is needed for the conservation of the birds and their habitats.

: The Chinese pond mussel Sinanodonta woodiana (Lea, 1834) (Bivalvia: Unionidae) is among the most invasive freshwater species worldwide. The last decades have seen its rapid geographical spread beyond the species’ natural range, particularly in anthropogenically modified water bodies across Asia, America, and Europe where it is now very common. In this paper, we also confirm the presence of S. woodiana in Africa (Algeria) by establishing the UNESCO Biosphere Reserve and Ramsar site Oubeira Lake as a new locality for its occurrence. In all likelihood , S. woodiana was accidentally introduced in the 1980s with Asian fish species imported from Hungary for stocking purposes. The present survey was conducted in the summer of 2020

: Fatty acid composition and otolith shape variation of six commercially important fishes, which differ ecologically in their living and feeding habits across the Gulf of Tunis, Tunisia, were analyzed. The aims were to investigate the discrimination and relationship between the six species using both fatty acid composition and otolith shape to examine whether variability in fatty acid composition is consistent with variation in otolith shape and check whether otoliths shape and fatty acids composition have combined characteristic signals for these species. Tukey’s test with one-way ANOVA indicated significant differences in total percentages of saturated (SFAs), polyunsaturated (PUFAs), and monounsaturated (MUFAs) fatty acids between individuals of the six species, and only between males and females of Gobius niger , and Trachinus draco . Discriminant function analysis (DFA) separated the six species into two main distinct clusters or groups. The first group comprised Mullus barbatus , G . niger , and T . draco , which assume a benthic life, while the second included Sardina pilchardus , Trachurus mediterraneus, and Chelon auratus , which are benthopelagic to pelagic species. Wilk’s λ test and Fisher’s distance ( D ) matrix showed a significant bilateral asymmetry in the left and right otoliths shape between individuals of the six species, as well as only between males and females of C . auratus , T . mediterraneus , and G . niger . However, a significant bilateral asymmetry was found only between females of G . niger and males of T . draco . DFA and hierarchical ascending classification (HAC) based on otolith shape variance revealed two main groups of otoliths congruent to those obtained from fatty acid composition analysis. The results indicated that fatty acid composition analysis was compatible with otolith shape analysis, and both have combined characteristic signals for these species and validated the use of fatty acid composition and otolith shape analyses as an effective approach to discriminate between and within these species.
对突尼斯突尼斯湾6种重要商业鱼类的脂肪酸组成和耳石形状变化进行了分析，这些鱼类在生态上的生活和摄食习性不同。目的是利用脂肪酸组成和耳石形状来研究6种物种之间的区别和关系，以检验脂肪酸组成的变化是否与耳石形状的变化一致，并检查耳石形状和脂肪酸组成是否结合了这些物种的特征信号。Tukey的单因素方差分析表明，6种鱼的饱和脂肪酸(sfa)、多不饱和脂肪酸(PUFAs)和单不饱和脂肪酸(MUFAs)的总百分比在个体之间存在显著差异，并且仅在黑Gobius和Trachinus draco的雄性和雌性之间存在显著差异。判别函数分析(Discriminant function analysis, DFA)将6种植物划分为两个不同的主要聚类或类群。第一组包括马刺，G。和T。第二种包括沙丁鱼、地中海沙鱼和auratus，它们是底栖到远洋的物种。Wilk’s λ检验和Fisher’s distance (D)矩阵显示，6种个体的左右耳石形状存在显著的双边不对称，且仅存在于C的雌雄之间。奥拉图，T。地中海和G。尼日尔。然而，显著的双侧不对称仅在G。黑曲霉和雄性黑曲霉。德拉科。DFA和基于耳石形状方差的分层上升分类(HAC)显示，两组耳石与脂肪酸组成分析结果一致。结果表明，脂肪酸组成分析与耳石形状分析是兼容的，两者都结合了这些物种的特征信号，并验证了脂肪酸组成和耳石形状分析是区分这些物种和物种内部的有效方法。

: Oxyclozanide is a salicylanilide derivative anthelmintic drug with a well-known effect on parasites that cause infections in humans and animals. In this study, the effect of oxyclozanide on DNA damage in hemocytes of Galleria mellonella (L.) (Lepidoptera: Pyralidae) larvae, which has been used as a model organism in many fields, was investigated. Hemolymph was collected from the last instar larvae (7th instar) reared on artificial diets containing oxyclozanide at different concentrations (0.003%, 0.03%, 0.3%, and 1.5%) under laboratory conditions and then hemocytes suspension was prepared. Genotoxic damage in hemocytes was determined by the comet assay which enables microscopically detecting DNA damage and is a very sensitive assay in chemical genotoxicity. When compared to the control group, tail length, tail DNA percent, and tail moment values were significantly increased parallel with increasing oxyclozanide concentrations. While the tail length was determined as 5.11 ± 0.46 µm in the control group, it was significantly increased in all tested groups to 13.17 ± 0.53, 27.98 ± 1.08, 98.44 ± 0.77, and 137.67 ± 0.74 µm, respectively. Similarly to tail length, tail DNA percentage and tail moment levels were also significantly increased from 12.86 ± 0.74 to 91.96 ± 0.31 at the highest concentration of oxyclozanide. These results showed that oxyclozanide caused DNA damage in the hemocytes of G. mellonella . It is also known that hemocytes are an important bioindicator in determining the genotoxicity of anthelmintics to be used as insecticides within environmentally friendly limits. It is thought that our results will contribute to the studies in this field.

: Nest site selection differs among species based on a characteristic crucial to the embryo’s survival. The identified nest-site characteristics of the Euphrates softshell turtle highlight that these turtles, like their other soft-shelled relatives, highly prefer the sandy substrate, even pure sand, to nest. However, alteration and loss of natural habitats for many decades limited the suitable oviposition sites along the Euphrates River. This study presents the uncharacteristic nest-site choice and the nesting time of Euphrates softshell turtle for the first time. I discovered four nests, as well as six unhatched eggs in a nest on 20 August 2017. This discovery extends the known nesting season-end from early June to at least mid-August for the Euphrates River. The eggs were spherical, and their size was 28.38 (±0.2, 28.1–28.6) mm on average. The nesting substrate, consisting of only 51.8% sand, was substantially dissimilar to what was previously reported. Apart from the soil texture, the nest and its site characteristics concerning nest dimension, clutch size, egg size, and distance to the shoreline concord with what was formerly reported. I conclude that many anthropogenic alterations, such as sand mining and damming and hence the scarcity of suitable oviposition sites, may have caused location and time shift of breeding and forced the turtles to nest in these uncommon soil textures

: The importance of underground hibernacula for the conservation of bats and monitoring their populations is well-recognized. However, the lowland territory of Belarus, with absent natural caves and suitable for bats mines, was one of the least surveyed European regions in terms of underground bat sites, and especially hibernacula. To address this knowledge gap, in 2020, we conducted a broad-scale one winter bat survey, exploring 90 underground sites (basements, cellars, church crypts, fortifications, and facilities of abandoned Soviet missile bases) in various parts of Belarus. To our knowledge, none of these sites had been examined for bats before. In 56 of the 90 underground sites, we discovered hibernating bats (a total of 1054 ind.) of six species: Barbastella barbastellus (78.5% of all bats), Myotis daubentonii (7.4%), Plecotus auritus (5.1%), Eptesicus nilssonii (4.9%), Myotis brandtii and Eptesicus serotinus (in sum, 2%). The distribution of bats among the hibernacula was highly uneven (with N Me = 3; N av = 19 ind.). In 76% of the hibernacula, the number of bats was between 1 and 10 individuals per site, which accounted for approximately 10% of all bats recorded during the survey. Only in five sites we found over 50 bats. One to four species were present in each site, with one species found in 58% of the hibernacula. We suppose that the small number of species and relatively small number of bats per hibernaculum is characteristic of the study region. This supports the
