: Some biological characteristics and life table of Mulberry scale [ Pseudaulacaspis pentagona Targioni-Tozzetti (Hemiptera: Diaspididae)], which is an important thermophilic, invasive, and polyphagous pest of fruit trees, was investigated. The research has been conducted at 7 different temperatures (20.6, 23.2, 27.1, 29.0, 30.6, 31.3, 33.8 ℃ ) on two different mulberry species ( Morus alba and M. nigra ) in the climate chambers with fixed illumination regime (16 : 8 h) and relative humidity (60% ± 5%) conditions. The total longevity of female individuals on M. alba were 120.54, 86.79, 63.54, 57.51, 41.35, and 26.27 days, while 110.61, 99.62, 63.84, 70.92, 40.23, and 50.94 days on M. nigra . At these temperatures, the intrinsic rate of increase ( r ) of P. pentagona on M. alba were –0.012, 0.045, 0.078, 0.066, -0.022 day-1, while –0.019, 0.003, 0.052, 0.043, –0.039, and –0.076 day -1 on M. nigra , respectively. According to the study results, it was found that the population parameters of P. pentagona were generally higher for populations fed on white mulberry than for populations fed on black mulberry, at most of the different temperatures tested. Using the results of this study, it was concluded that black mulberry in regions with optimum temperatures between 23–29 ℃ and white mulberry in warmer areas (29 ℃ and above) would be more appropriate in terms of control P. pentagona .

Herewith, the current status of the inland waters ichthyofauna of Türkiye is revised, and an updated checklist of the freshwater lampreys and fishes is presented. As of November 2023, the freshwater ichthyofauna of Türkiye is known to consist of 427 species belonging to 20 orders, 37 families, and 97 genera. Among these, 21 species (4.9%) are alien, and 215 species (50.4%) are considered endemic to Türkiye. The orders with the largest numbers of species in the ichthyofauna of Türkiye are the Cypriniformes (297 species, 69.6%), followed by the Cyprinodontiformes (26 species, 6.1%), the Salmoniformes (25 species, 5.9%), the Gobiiformes (20 species, 4.7%), the Siluriformes (13 species, 3.0%), and the Clupeiformes (9 species, 2.1%). At the family level, the Leuciscidae has the greatest number of species (126 species; 29.8% of the total species), followed by Nemacheilidae (63 species, 14.8%), Cyprinidae (59 species, 13.8%), Cobitidae (29 species, 6.8%), Salmonidae (25 species, 5.9%), Aphanidae (23 species, 5.4%), Gobiidae (20 species, 4.7%), and Gobionidae (15 species, 3.5%). According to IUCN Red List criteria, among 403 naturally distributed species (alien species not included), four fish species are extinct, and 99 species (24.4%) are classified as threatened extinctions, including 28 (6.9%) CR, 44 (10.8%) EN, and 27 (6.7%) VU. After the latest checklist published in 2020, a total of 56 species, including 26 newly identified species from Türkiye and 30 new records documented from Turkish inland waters, were added. By the way, a total of 17 species have been excluded, mostly because of synonymization.

Multidisciplinary approaches for the conservation of endangered species have great importance in preparing management plans. In addition to ecological and population demographic parameters, genetic data provide vital information for conservation management plans for a species. The Hermann's tortoise (Testudo hermanni) suffers from illegal trade, fires, habitat fragmentation and destruction, and therefore, the genetic diversity of the regional populations has been affected. It was aimed herein to impart knowledge on the population genetic structure of T. hermanni boettgeri, listed as near threatened by the International Union for Conservation of Nature Red List as a subspecies and has limited distribution in European Türkiye. A study was conducted of 15 microsatellite loci of 221 tortoises from 15 different localities in the Thrace region in Türkiye. All of the examined loci were polymorphic, and the number of alleles varied from 2 to 13. The quantity of private alleles (Pa) at the localities ranged from 0 to 6. The average gene diversity was 0.31 (range: 0.25-0.38). The highest levels of allelic richness, private alleles, and genetic diversity (Ar, Pa, He) were observed at localities 3 and 7, close to each other. The total population (p < 0.001) and 12 of the 15 studied localities diverged from the Hardy-Weinberg equilibrium. Of the 15 localities studied, 6 had significantly different inbreeding coefficients. Furthermore, a 2-phased model of mutation (TPM) (p < 0.001) detected a recent bottleneck in the population. The population genetic results identified 8 groups with significant genetic structure (F$_{ST}$ = 0.166, p < 0.01) in 2 large clusters (K = 2).

: Heavy metal toxicity is a significant threat to human health and the environment. Contamination of the food chain with heavy metals in water sources may impact the health of consumers adversely. This study aimed to determine the concentrations of Pb, Cd, Cr, Cu, and Zn in the invasive fish species Carassius gibelio inhabiting two important lakes in Türkiye: Lake Beyşehir and Lake Eğirdir, from the Lake District Region and assess any health risks posed by the consumption of these species. For this purpose, C. gibelio species were obtained from two lakes in dry and rainy seasons and heavy metal concentrations were determined via ICP-OES analyses. The Cd concentrations in the muscle samples obtained from both lakes were below the analysis limits. The mean heavy metal concentrations (mg/kg) in the Beyşehir and Eğirdir lake samples were found as Pb: 0.32, Cr: 0.09, Cu: 0.52, and Zn: 6.88 and Pb: 0.88, Cr: 0.08, Cu: 0.46, and Zn: 12.6, respectively. The average heavy metal concentrations in the muscle tissues were below the national/international legislation limits, and the estimated daily intake (EDI), target hazard quotients (THQs), total THQs (TTHQs), and carcinogenic rates (CRs) did not exceed these limits. The results suggested that the consumption of these invasive fish species from these two lakes might not pose any potential health risk for consumers. Transference values (TF) for the digestive tract were also calculated, and biomagnification was determined for Pb, Cd, and Cr. Risk assessment studies are very important in terms of evaluating the effects of fish consumption on human health via applying different indices. This is the first study in which heavy metal concentrations were determined simultaneously in Lake Beyşehir and Lake Eğirdir, and the public health risk of consuming their invasive fish species was estimated.

The aim of this study was to compare the speed of movement of 3 species of ants (Formica rufa, F. polyctena, and Lasius fuliginosus) along trails with different types of substrates. The study took place from June to August 2022 within the Holosiyivo Forest, located in Kyiv, Ukraine. For L. fuliginosus, the study was conducted in August and September 2022. For the experiment, 3 colonies of each species were selected in June, with only 3 trails passing on substrate (a total of 9 trails). One of the trails was left unchanged (ground surface), smooth logs were laid on the second and bark on the third. The movement speeds of the ants were measured for each substrate type (s/10 cm) by examining the individual trajectories of each worker (4678 in total). When the highway trajectory did not coincide with the trail and followed the shortest path instead, the ants did not cross the highway or crossed it only in some sections. In August 2022, all of the highways were relaid after the trail trajectories were recorded. Within a week or a week and a half, the ants switched completely to the highways. Larger-sized ant species (F. rufa, F. polyctena) moved 1.6 to 1.9 times faster than the smaller ones (L. fuliginosus) across all of the substrate types. For one of the species, the movement speeds differed between the different substrate types. F. rufa moved 62% slower on the ground surface than on logs, F. polyctena 50% slower, and L. fuliginosus 61% slower. Of the 3 substrate types, the ants preferred logs on highways the most. Ant movement on the logs was in all cases associated with the maximum speed, at 38%-50% faster than on the ground surface. While the F. rufa workers transported a similar amount of food per unit of time on both the bark and the ground surface, they transported 1.75 times more food on the logs than on the ground surface and 1.15 times more than on the bark. For F. polyctena, the highest amount of food transported on the logs was slightly less than that on the bark (1.13 times) and the lowest on the ground surface (4.15 times less than on the logs and 3.64 times less than on the bark). The usage of highways accelerates colony growth and artificially creates a nest site by improving trail infrastructure. Future studies should compare the growth rate of nest mounds over time in colonies of red wood ants with and without artificial trail networks

: Chama coralloides Reeve, 1846 is a commercially important mollusk in Acapulco, Mexico. There is currently no fisheries regulation or protection. Therefore, the objective of the present work was to estimate the growth parameters of C. coralloides using the Schnute model cases. Shell length data collected from March 2019 to December 2021 were used. A multinomial analysis was performed to determine the modal groups monthly. Using the mean lengths of each modal group, a modal progression was performed to define the time increments ∆ t , which were taken as equivalent representations of the data from direct age estimation methods (mark-recapture). These data were used to estimate the individual growth parameters using the five cases of the Schnute model and to define the case that best describes the growth. 2804 organisms were analyzed, with lengths ranging from 7.61 to 116.30 mm SL. Multinomial analysis showed one to four modal groups per month and 14 cohorts were identified. The best-fit case was case 5 ( wi = 0.72) with an L ∞ = 114.2 mm, followed by case 1 (wi = 0.28) with an L ∞ = 109.8 mm. Both cases (5 and 1) were modeled and because the best model did not reach 90%, a mean model was estimated. C. coralloides presented a type of asymptotic growth, with an estimated L ∞ that can be reached nearly 22 years.

: Hypopigmentation is characterized by the lack of melanin in part or the whole body. For nocturnal or fossorial reptiles, hypopigmentation may be less disadvantageous, as they are less exposed to visually oriented predators. But chromatic anomalies are challenging to observe in fossorial species, such as worm lizards (Amphisbaenia), because they are difficult to detect in the wild. We assessed information on hypopigmentation in the worm lizard genus Blanus based on two citizen science platforms and found the first record of piebaldism in B. aporus , new records of piebaldism in B. vandellii and B. strauchi , and the first record of amelanism in B. cinereus . This underscores the relevance of citizen science for obtaining new data on chromatic anomalies in fossorial animals. Hypopigmentation occurs more frequently in Blanus than previously known and most, if not all new records were observed in adults, supporting the hypothesis that this chromatic anomaly is less disadvantageous to fossorial reptiles.

: Countries with heterogeneous climatic and geographic characteristics may find it challenging and limiting to fulfill the requirements of the Water Framework Directive (WFD), such as defining ecoregion and water body types. To overcome this limitation, they implement optional factors in addition to the obligatory factors defined in the WFD. As a candidate country, Türkiye is required to comply with the WFD requirements and must determine its own optional and obligatory factors. In this context, we addressed the relevance of Chironomus spp. in determining these factors. We used twenty distinct national lake typologies for Türkiye and identified a total of 24 Chironomus species. The Chironomus genus was found to be effective in determining the optional factors. Statistical analyses revealed that fetch, altitude, salinity, water temperature, pH, saturated and dissolved oxygen, conductivity, orthophosphate, ferrous ion, chloride, and nitrogen compounds were significant in discriminating the regions. The canonical correspondence analysis (CCA) explained 56.62% of the variance. We also statistically analyzed the effectiveness of the class boundaries of the obligatory factors used in Türkiye for regionalization. Among the official obligatory factors, only the altitude boundaries gave a significant result and explained a total of 62% variance. We recommend revising the class boundaries of obligatory factors and using fetch data as a significant genuine parameter for lake typology as an optional factor
