Coastal floodplains are among the most modified landscapes in southeastern Australia. We used available vegetation survey data for coastal alluvium and other unconsolidated Quarternary sediments to construct a diagnosis of the major plant communities and document their flora. We used soil landscape maps and historical portion plans to gain an understanding of the distribution and environmental relationships of the communities. The flora of coastal floodplains includes more than 1 000 native vascular plant taxa and more than 200 introduced taxa. The introduced flora is likely to be considerably larger, given that sampling was biased toward the least disturbed sites. Six major plant communities were diagnosed including a rainforest found north from the Shoalhaven floodplain, a mixed forest of eucalypts and melaleucas found north from Jervis Bay, a casuarina forest (sometimes with melaleuca) found throughout the coast, one open eucalypt forest found principally south from the Hunter region, another open eucalypt forest found north of the Hunter region and a complex of treeless wetland assemblages scattered throughout the coast. The extent and spatial arrangement of these communities varies between floodplains, with landform, rainfall, water regime and soil properties including moisture, fertility and salinity thought to be important factors mediating their distribution patterns. All six assemblages are listed as Endangered Ecological Communities under Threatened Species legislation. The coastal floodplain communities continue to be threatened by land clearing and crop conversion, fragmentation, changes to water flows, flooding and drainage, input of polluted runoff, weed invasion, activation of acid sulphate soils, climate change and degradation through rubbish dumping and other physical disturbances.

AbstractThe Gangjia granite stock is a garnet-bearing muscovite leucogranitic body emplaced in Yiwulüshan in Western Liaoning Province at the eastern segment of the Yanshan orogenic belt, North China craton. The SHRIMP U–Pb zircon age is 153±5 Ma. The Gangjia granites are peraluminous with A/CNK of more than 1.14, and exhibit a tetrad effect in their REE distribution patterns, as well as non-charge-and-radius-controlled trace element behaviour. This is in contrast to the LREE-enriched patterns of the host Lüshan monzogranites. These geochemical characteristics, together with low Th/U ratios in zircon, suggest that the parental magmas for the Gangjia granites have experienced extensive magmatic differentiation, including interaction between residual melt and a coexisting high-temperature aqueous fluid. Their similar ϵNd(t), model ages, compatible age patterns and common volcanic arc signature in source materials between the Gangjia granites and the host Lüshan monzogranites indicate their comagmatic relationship. These unusual peraluminous leucogranites, coupled with the voluminous adakitic granites hosting them, represent typical post-orogenic magmatism developed under an intra-continental extensional tectonic regime. At the very end of the prolonged Jurassic magmatic evolution in Western Liaoning, extensive fractionation of most probably ferromagnesian phases and plagioclase from a calc-alkaline magma parental to the host Lüshan pluton, with overprint of the magmatic hydrothermal fluid, produced highly evolved peraluminous parental magmas for the Gangjia granites.

This article, which is the first contribution in a series on the ruderal vegetation of the city of Kyiv, presents results of our studies of Stellarietea mediae plant communities occurring in the city. Their current state and phytocoenotic diversity has been determined. Based on modern methods of statistical data analyses, a classification scheme of Stellarietea mediae vegetation in the study area was developed and the leading factors of territorial and ecological differentiation of phytocoenoses were identified. It has been established that within Kyiv City, this class is represented by 24 associations and 3 basal communities belonging to 8 alliances and 4 orders. Their territorial distribution determines the types and intensity of anthropogenic disturbances, as well as the types of soil and its mechanical structure. Selected syntaxa are characterized and compared with their equivalents from other areas of Ukraine. It has been found that the main differences are at the level of co-occurring species, the composition of which mostly correlates with the types of anthropogenic disturbances and availability of water and mineral nutrients. According to the results of the ordination, it has been found that the distribution patterns of plant communities of Stellarietea mediae occur along the salt regime gradient of the edaphotope, as well as of ombro-, cryo-, and thermal regimes of the climate. Based on the phytoindication analysis, the ecological optimums of the plant communities in relation to the leading ecological factors were determined. The performed research supplements the available information about the presence and distribution of such associations as: Digitarietum ischaemii, Setario viridis-Erigeronetum canadensis, and Ambrosietum artemisiifoliae, in the territory of Ukraine. The proposed syntaxonomic scheme should become a basis of typological developments for strategic planning and practical implementation of activities for optimizing the urban environment and for sustainable development of the Kyiv urban agglomeration.
