  Importance of Biotic and Soil Factors in Determining the Distribution Strategies of Coastal Salt Marsh Plants	The distribution of plant communities in the salt marshes of the southwestern coasts of South Korea was studied, along with environmental or plant factors, by canonical correspondence analysis (CCA) and the competitor (C), stress tolerator (S), and ruderal (R) (CSR) ecological strategies. The coastal salt-marsh plants were classified into three plant-factor groups in the CCA biplot diagram. Group 1 was correlated with LS and FP. Group 2 was correlated with CH and SLA, and Group 3 was correlated with LA, LDMC and LDW. The salt-marsh plants were classified into four soil-factor groups in the CCA biplot diagram. First, the group factor was correlated with TN, TOC, and Ca2+. Second, the group factor was distributed according to Mg2+, soil texture as Clay and Silt. Third, the group factor was distributed according to Salinity and Na+ content. Fourth, the group factor was distributed according to Sand content. To clarify the relative significance of competition, stress, and disturbance in the distribution process of plant communities, the CSR distribution model was adopted. The nine species showed CR (competitor-ruderal) strategies: Artemisia fukudo, Artemisia scoparis, Aster tripolium, Atriplex gmelinii, Imperata cylindrica var. koenigii, Salicornia europaea, Suaeda japonica, and Suaeda maritima. The four species with C (competitor) strategies were Artemisia capillaris, Limonium tetragonum, Triglochin maritimum, and Zoysia sinica. Carex scabrifolia and Phragmites communis displayed SC (stress-tolerant-competitor). Both distribution patterns of the CCA diagrams and CSR triangles may provide a useful scientific basis for protecting and restoring salt marshes and their valuable ecosystem services, considering the increasing disturbances.

  Salt tolerance during germination identifies native intertidal plant species at risk under increasing salinity with sea level rise	Climate change and sea level rise are causing an increase in salinity in coastal salt marshes around the world. These changes may alter the germination dynamics of some halophytes, threatening their conservation. Our study area (Atlantic coast of the southwestern Iberian Peninsula) is currently being affected by sea level rise, and increases in sediment salinity have been recorded. We studied the germination responses during and after a wide range of imposed salinities (0-600 mM) of 5 Asteraceae species; 3 colonizing salt marshes (Artemisia caerulescens, Aster tripolium and Inula crithmoides) and 2 (Dittrichia spp.) inhabiting adjacent non-tidal environments. In addition, habitat characteristics (plant cover, sediment redox potential, electrical conductivity, pH, water content and bulk density) associated with each marsh species were measured and compared with the spatial distribution of the Asteraceae species in the field and their capacity to germinate at different salinities. The germination syndrome of Aster tripolium and Inula crithmoides was characterized as germinating in salinity ranging from fresh water to 600 mM salinity (36 ppt). The rare halophyte A. caerulescens and the 2 non-tidal Dittrichia species presented a germination syndrome based on no germination at high salinities and high recovery germination (55-80%). Considering the high sensitivity of A. caerulescens to salinity during germination, active conservation measures are recommended to promote its preservation in the Mediterranean Basin. These include creating new populations and promoting salt marsh connectivity to facilitate the processes of species mobility and marsh migration to uplands where sediment salinity is lower.

  Investigation of soil permeability and suitable vegetation for rain gardens in Kecskemet	Nowadays, the implementation of integrated stormwater management is an important element of urban climate adaptation. Rain gardens are part of this system, which effectively handles large amounts of sudden precipitation. In this way, they are suitable for preventing the increasing frequency of flash floods. For rain gardens, it is important to collect information about the soil and the vegetation.We examined the permeability of the typical soil types in Kecskemet ？ humus sandy soil, solonetz meadow soil ？ and Bacsviz compost, in order to decide what proportion of soils and compost can be considered ideal for rain gardens. In addition, experiments were performed with three broad-tolerant plants (Inula Britannica, Aster tripolium subsp. pannonicus and Limonium gmelinii) planted in the studied soil types and compost, as well as in a mixture of these. Based on our results, it can be concluded that the solonetz meadow soil practically means a waterproof layer, while a mixture of half of this soil type and compost already has adequate water permeability and water storage properties, which provide the necessary living conditions for plants.

  Acomparative Anatomical Study of the Species Aster subulatus and Aster tripolium (Asteraceae) inTikrit- Iraq.	The two species Aster subulatus and Aster tripolium have been studied in the present study. It involves an anatomical study of epidermis of the leaf, the anatomical characters of diameters, and the numbers of epidermal cell stomata and Indumentum are found to be considerable in taxonomic value which separated and diagnostic both species. The abesence of the hairs on both sides upper and lower epidermis of the leaf have been showed. Also there are many differences in average of stomata numbers on both epidermis surfaces in both studied species. So the characters Also queditatie such as the shape and thickness of epidermis and the stomata are found to be with taxonomic value.	Hisham majeed shlash		상세보기
