“…This change in observed dune morphology is attributed to changes in foredune species dominance (Godfrey and Godfrey, 1973;van der Valk, 1975;Woodhouse et al, 1977;Godfrey, 1977;Godrey et al, 1979). From Virginia northward, foredunes are dominated by Ammophila breviligulata (American beachgrass), while south of Virginia, Uniola paniculata (sea oats) dominates foredunes (Wagner, 1964;Godfrey, 1977;Duncan and Duncan, 1987;Lonard et al, 2011). On the east coast, A. breviligulata and U. paniculata exhibit similar rates of vertical growth (including the adapted response of increasing growth rates when buried by moderate amounts of sand; Disraeli, 1984;Maun, 2004;Ehrenfeld, 1990;Lonard et al, 2011;Wagner, 1964).…”

However, A. breviligulata and U. paniculata exhibit differences in rates of lateral growth: 1-3 and 0.6-1 m yr −1 respectively (Woodhouse et al, 1977;Ehrenfeld, 1990;Lonard et al, 2011).…”

The slower lateral growth rate of U. paniculata provides a potential explanation for the observation of hummocky dunes along the southeastern US coast.…”

Lateral vegetation growth rates exert control on coastal foredune hummockiness and coalescing time

Abstract. Coastal foredunes form along sandy, low-sloped coastlines and range in shape from continuous dune ridges to hummocky features, which are characterized by alongshore-variable dune crest elevations. Initially scattered dune-building plants and species that grow slowly in the lateral direction have been implicated as a cause of foredune "hummockiness". Our goal in this work is to explore how the initial configuration of vegetation and vegetation growth characteristics control the development of hummocky coastal dunes including the maximum hummockiness of a given dune field. We find that given sufficient time and absent external forcing, hummocky foredunes coalesce to form continuous dune ridges. Model results yield a predictive rule for the timescale of coalescing and the height of the coalesced dune that depends on initial plant dispersal and two parameters that control the lateral and vertical growth of vegetation, respectively. Our findings agree with previous observational and conceptual work -whether or not hummockiness will be maintained depends on the timescale of coalescing relative to the recurrence interval of high-water events that reset dune building in low areas between hummocks. Additionally, our model reproduces the observed tendency for foredunes to be hummocky along the southeast coast of the US where lateral vegetation growth rates are slower and thus coalescing times are likely longer.

Halophyte species of United Arab Emirates are a source of unique active phytochemicals, potentially due to the extreme environmental conditions under which the plants grow in the UAE. These phytochemicals make the native halophytes possibly interesting crops for biorefining, where biofuel production is combined with the production of value added chemicals, improving the economic feasibility of both process. Phytochemicals found in these species are widely recognized and researched as potential pharmaceutical and nutraceutical products. We reviewed the literature for secondary metabolites from species from the following halophyte families: Aizoaceae, Amaranthaceae (incl. Chenopodiaceae), Avicenniaceae, Zygophyllaceae. The review revealed that plant species belonging to these families contain valuable phytochemicals, such as fatty acids, terpenoids, flavonoids, alkaloids, steroids, tannins, saponins, quinones and coumarins, many of which have been reported to have therapeutic effects in humans.

“…As hastes que apresenta na superfície podem atingir 8 m de comprimento (Leonard;Judd, 1997). Espécie heliófita que prefere locais estáveis como dunas semifixas (Rizzini, 1997) Além da descrição apresentada no Quadro 1, é relevante destacar de que maneira estas espécies estão situadas na paisagem dunar e atuam no ambiente.…”

O artigo objetiva investigar espécies endêmicas de dunas capazes de indicar a situação ambiental da área de Barra dos Coqueiros cogitada para criação de uma Unidade de Conservação, Sergipe, a partir do potencial fitogeográfico revelado pela modelagem de distribuição de espécies. Por meio do software MAXENT foram analisadas sete espécies endêmicas de dunas incipientes e semifixas. Os potenciais distributivos estabeleceram que a R. maritima, por sua taxa de dispersão próxima de um, é importante para recuperação de áreas litorâneas. Todavia, a I. imperati, com taxa de predição próxima de zero é a fitoindicadora de vulnerabilidade/fragilidade. A pesquisa aponta que novas ações planejadas precisam ser efetivadas para a real conservação da biodiversidade em Sergipe.
