Evapotranspiration calculation is an important matter due to agricultural reasons, but also for understanding water resources and runoff amount in a certain territory. Two CMIP5 multimodel projections (2011‐2040 and 2041‐2070) and land cover pattern were used to analyse the seasonal and annual crop evapotranspiration trend in Turkey. The spatial distribution of crop evapotranspiration related to initial season, mid‐season, end‐season and cold season were computed through geographic information system. The maximum values of crop evapotranspiration were found in the mid‐season for present and future, with values of 1072 mm, respectively, 1241 mm. For the future period, an increase in spatial distribution of crop evapotranspiration has been depicted in several places due to climate warming, mainly in the southern and southeastern sides of Turkey and on the Mediterranean Coast. The minimum values of seasonal crop evapotranspiration fall below 154 mm and 164 mm in the present, respective in the future. The annual crop evapotranspiration increased from 1675 mm to 1944 mm from present to future and the significant values of absolute changes were identified in the western, eastern and southeastern regions of Turkey. The findings are useful for scientists in climate, hydrology, and agriculture fields, but also for the management decisions.

Tussilago farfara L., a perennial species, is a medicinal herb used in traditional medicine, mainly for the treatment of respiratory tract-related pathology. In traditional Chinese medicine, flower buds are preferred; in Europe, the leaves are used; and in some parts of India, the whole plant is utilized. This preferential usage of the plant organs might be based on differences in the chemical composition due to environmental conditions, along with preferred traditional and cultural approaches. In this article, the impact of pedoclimatic growth conditions on the morpho-anatomical development and phytochemical profile of the plant were studied on T. farfara in the vegetative state, collected from two different locations in the Romanian spontaneous flora, revealing significant variations. Furthermore, the antioxidant profile of the specific extracts from the aerial and subterranean plant parts is also in accordance with these discrepancies. The plant anatomy was assessed histologically by optical microscopy, while the analytical chemistry evaluation was based on LC/MS and spectral methods for the evaluation of the antioxidant and enzyme inhibitory activity. To our knowledge, this is the first comparative analysis contextually reporting on the histology, phenolic profile, antioxidant capacity, and geographical location of the vegetative form of T. farfara.

The variation of tourism flow and its spatial representation are indispensable for transport companies, accommodation facilities and future estimations regarding the international arrivals. The major implication for tourism flow mapping is related to the country of origin of tourists, their liquid assets, and tourism statistical database. The approach of tourism flow mapping representation, at least using lines and density, should be based on the spatial characteristics of the objects. In this study, the database consisting of international arrivals in different cities of Romania was used as an example. Thus, GIS-based Kernel density of the tourists’ flow was proposed. To illustrate the international demand, data on arrivals for 33 countries over the period 2015-2017 were used. ‘XY To Line’ and ‘Kernel Density’ functions served to create the convergence lines between the origin countries and Romania. The very high density was found for the European countries with an increase of 13% and 25% between 2015 and 2016, as well as between 2015 and 2017. Map analysis indicated an increase of the density area by 0.7% for 2016 and 1.7% for 2017. The proposed methods, including lines and density, contribute to the mapping of the flow of the international arrivals in Romania.

The habitat of the European mudminnow, Umbra krameri Walbaum, 1792, is continuously decreasing due to human intervention. The species has a “vulnerable” status according to the IUCN Red List. Thus, new information about the species is needed for conservation efforts. Minnow traps were used for capturing Umbra krameri and other small fishes in the Jieț River, Dolj County, southwestern Romania. Captured specimens of U. krameri were measured and weighed. Length–weight relations and relative condition factor were determined for the captured U. krameri specimens. A total of 94 fishes were captured using the minnow traps. They represented 7 species: European bitterling, Rhodeus amarus (Bloch, 1782), roach, Rutilus rutilus (Linnaeus, 1758), rudd, Scardinius erythrophthalmus (Linnaeus, 1758), Danubian spined loach, Cobitis elongatoides Băcescu et Mayer, 1969, weatherfish, Misgurnus fossilis (Linnaeus, 1758), tubenose goby, Proterorhinus marmoratus (Pallas, 1814), and U. krameri. The specimens of Umbra krameri represented 44% (41 specimens) of the total catch. The wet body weight (BW) of U. krameri ranged from 0.8 to 5.1 g, having a mean value of 2.102 g. The mean total length (TL) was 5.782 cm, ranging from 4.59 to 7.87 cm. According to the length–weight relation (LWR), the growth type of U. krameri was positive allometric based on the determined equation: BW = 0.0068TL3.277. The mean value determined for the relative condition factor (Kn) was 1.0056486. The growth condition of 46% of the specimens was poor (Kn < 1; n = 19), while the other 54% were in good condition (Kn ≥ 1; n = 22). The presently reported study provides information about the presence of U. krameri in the Jieț River (Dolj County, Romania), a location where the species has not been previously reported. The LWRs show an allometric positive growth. The relative condition factor shows that 46% of the specimens had poor growth, while the rest were in good condition. Minnow traps were an efficient tool for small fish capture.
