Changes in C and nutrient cycling during succession are well studied, however, results can be contrasting for different nutrients and successional sequences. We analyzed soil chemical differences between early and late succession of oak-hornbeam forest. Late forest succession efficiently retained plant-available P, and total Mn, Zn, Fe, Cu, and Ni pools in the soil, as their concentrations were similar to those of early-successional grasslands. Available K, soil organic C, and organic matter content, as well as C:N and C:S ratios were higher in late than in early succession. Soil organic N and S concentrations did not differ between the stages.

Juniperus L. is a very diverse genus of dioecious or monoecious conifers distributed throughout the Mediterranean region. In addition to the complex taxonomic characteristics of the genus, sexual dimorphism leads to sex-specific differences in the morphology of juniper species, which further complicates the delimitation of species. Two of these species, Juniperus oxycedrus L., which occurs in the western part of the Mediterranean, and J. deltoides R.P.Adams, which occurs in the eastern part, have only recently been delimited as separate species. To further support the delimitation of the species, we examined the phenotypic traits of the cones and needles of both species for both sexes. Three populations from the western and three from the eastern part of the Mediterranean region were sampled and a total of 2400 needles, 1200 cones and 1200 seeds were measured and analyzed. Both needles and cones of J. oxycedrus were slightly larger, longer and wider than those of J. deltoides and also less variable. Sexual dimorphism was observed in most of the needle traits measured, with the majority of traits in J. oxycedrus being larger in females than in males. Although sexual dimorphism was confirmed based on needle morphology, no consistent pattern of diversity was observed between the two species. In addition, variability among populations of J. oxycedrus was higher than that of J. deltoides. Our results confirm the previous species delimitation and open the possibility for further exploration of sex-specific differences in adaptability, as well as the potential implications for differential management and conservation of individuals of both sexes.

Some interesting Astragalus L. (Fabaceae) specimens that have short stems, long stipules and short yellow petals were collected from Nallıhan, Ankara. In the careful examination made, it was seen that the specimens resemble Astragalus ovinus Boiss., A. fabaceus M.Bieb. and A. angustiflorus K.Koch belonging to the section Caprini, but it was determined that there is a difference due especially to some generative characters. After comparison with the closest taxa, it was decided that it is new for science and was named Astragalus nallihanicus. It grows at altitudes between about 850-1050 meters a.s.l. in a pine forest clearing. The size of some morphological features such as stipules (lower ones 17-22 mm long), calyx teeth (8-9 mm long), standards (19-22 mm long), wings (16-18 mm long), legumes (8.3-10.5 mm wide) and the dimensions of the seeds (3.5-4.1 x 2.1-2.5 mm), allow Astragalus nallihanicus to be distinguished from the closest taxa. Here, a description of the new species, comparison with similar taxa, informative photographs, and some ecological preferences have been given.

The holo-parasitic weed Orobanche crenata Forrsk. is a threat to economically important legumes and vegetables in Mediterranean countries, including Egypt. The crenate broomrape attacks several wild and cultivated plant species, and documentation of new hosts of the parasite is always required. To the best of our knowledge, this study is the first report of parasitism of the crenate broomrape on two ornamental species, Arctotis fastuosa Jacq. and Callistephus chinensis (L.) Nees. (Asteraceae). We also recorded for the first time its parasitism on the wild weeds (Ammi majus L., Lactuca serriola L., and Melilotus indicus (L.) All.) and the cultivated plant species (Carthamus tinctorius L. and Tropaeolum majus L.) from Egypt. The occurrence of O. crenata parasitism was confirmed by the attachment of its haustoria to the roots of host plants. The incidence of crenate broomrape disease was estimated for the seven species. The study also provides a morphological description of the polymorphic O. crenata on the samples from Egypt and determines the most useful characteristics for its easier identification in the field.

A culture-dependent method was used to isolate fungal endophytes from the leaves, stems, and roots of the invasive plant Solanum rostratum Dunal. growing in Xinjiang Province, China. All isolates were identified according to ITS (internal transcribed spacer) region of ribosomal DNA sequences and analyzed by Nucleotide BLAST according to NCBI GenBank and Mycobank database. Altogether 176 endophytic fungal isolates corresponding to 44 OTUs were identified, which were classified into 12 genera, with Penicillium (59.66%) and Aspergillus (23.29%) being the highly dominant genera. Ten endophytic isolates (OTU1, OTU15, OTU16, OTU21, OTU23, OTU25, OTU26, OTU30, OTU37 and OTU44) were identified as potential new species.

Due to increased consumption, artificial sweeteners are often present in the environment but their effects on plants are largly unknown. In this research, the effects of four artificial sweeteners on plant stress markers in Triticum aestivum L. were investigated. Wheat seedlings were grown from seeds in soil containing artificial sweeteners (saccharin, sodium cyclamate, sucralose, aspartame) in different concentrations (0, 25, 50, 100 mg kg-1). Plants were irrigated at regular intervals to maintain field capacity moisture and harvested after 15 days of growth. Electrolyte leakage, chlorophyll and carotenoid content, and antioxidant enzyme (superoxide dismutase, peroxidase, catalase) activities were determined in harvested leaves. Comparisons between control samples and test samples were statistically evaluated at a 95% confidence interval to determine significant differences. Overall, significant increases in chlorophyll and carotenoid content, and some antioxidant enzyme activities were observed in wheat plants exposed to artificial sweeteners in the soil. A significant increase in electrolyte leakage was observed with saccharin and aspartame treatment, indicating that these sweeteners can cause membrane damage in wheat. Chlorophyll a nd POX activity were the most sensitive stress parameters in wheat. This study showed the importance of evaluating the potential impact of anthropogenic pollutants that may be present in treated wastewater and consequently affect plants.

Cephalaria pastricensis subsp. pologensis Teofilovski (Dipsacaceae), is published as a new subspecies to science from NW North Macedonia. It is distinguished from C. pastricensis Dörfl. & Hayek subsp. pastricensis by its densely, ± patent-subvillous petioles and rachis of the leaves, and the midrib of the lower surface of the leaf lobes (vs. with sparse, short, ± appressed hairs), densely pubescent lower surface of the leaves (vs. with scattered hairs on the nerves), and densely pubescent to subglabrous upper surface of the leaves (vs. glabrous or with scattered hairs on the nerves). The new subspecies is a Macedonian endemic known from small areas in the Šar Mountains (near Brezno village) and Buković Mt. (near Gorna Đonovica village). Its distributional range is geographically separated from that of C. pastricensis subsp. pastricensis, which is Balkan endemic, distributed in Albania, Montenegro, Bosnia and Herzegovina, Kosovo, and Serbia.

In this local-scale synecological study, we investigated the changes in plant community composition throughout secondary succession occurring after cessation of agricultural land use (i.e. grassland abandonment). The successional sequence studied had the following pathway: Avenula pubescens (Huds.) Dumort. haypastures → Brachypodium pinnatum (L.) P.Beauv. successional grassland → Cornus sanguinea L. scrubs → late-successional Populus tremula L. forest → late-successional oak-hornbeam (Quercus-Carpinus) forest. The last forest stage was represented by the association Epimedio-Carpinetum betuli (Horvat 1938) Borhidi 1963. Occurrence of plant species throughout secondary succession was mostly stage-specific; only Fragaria vesca L., Ajuga reptans L., Cornus sanguinea, Prunus spinosa L., and Viola hirta L. showed survival ability throughout almost all stages.

The genus Elatine L. consists of ephemeral species of wet-land habitats that live in the temperate regions of both hemispheres. Because of their relatively fast life cycle and small habit, they lead inconspicuous lives, which is probably why they have been relatively little studied in European botany. Although the botanists of the 19 th and early 20 th century discovered all the currently recognised taxa, there were only a few studies that specifically addressed questions on their bi - ology. This lack of detailed knowledge triggered the more recent interest in this genus (especially the European members)
