“…Por estar mais distante do lençol freático, o desenvolvimento dessa espécie é influenciado por essa condição. Além disso, no cume das cristas praiais pode ocorrer uma maior lixiviação dos nutrientes, causando um empobrecimento nessas zonas, o que limita o crescimento da vegetação (Willis et al, 1959;van der Valk, 1975;Cordazzo, 1985). Nas depressões entre os cumes das cristas praiais, as condições para o desenvolvimento das plantas são melhores: ocorre uma maior proteção contra os ventos e o salsugem, diminuindo o estresse da planta e um maior acúmulo de matéria orgânica (Brown & Lugo, 1982;Frangi & Lugo, 1992).…”

Variation in aboveground biomass of Allagoptera arenaria (Gomes) O. Kuntze (Arecaceae) on the Marambaia beach ridge, Rio de Janeiro, BrazilVariation of aboveground biomass of Allagoptera arenaria (Gomes) O. Kuntze (Arecaceae) along five topographic profiles perpendicular to the ocean was examined in a palm scrub community on Marambaia beach ridge, Rio de Janeiro State, Brazil. Aerial biomass was positively correlated with distance from the sea (F = 39.57; R 2 = 0.69; P < 0.01) as was detritus cover (F = 525.92; R 2 = 0.92; P < 0.01). A. arenaria growth is closely related to the topography of the beach area. Dense populations of this palm enrich the soil by increasing organic matter under the plants through dead leaf material. This promotes the accumulation of nutrients and the creation of microclimates that favor the establishment of other species.Key words: biomass, Allagoptera arenaria, sandy coastal plain, Rio de Janeiro. RESUMOA variação da biomassa aérea de Allagoptera arenaria (Gomes) O. Kuntze (Arecaceae), ao longo de 5 perfis topográficos perpendiculares ao mar, foi analisada em uma comunidade arbustiva de Palmae, na restinga de Marambaia, RJ. Foi encontrada uma relação positiva e altamente significativa da biomassa aérea dessa espécie (F = 39,57; R 2 = 0,69; P < 0,01) e da cobertura de detritos (F = 525,92; R 2 = 0,92; P < 0,01) com o distanciamento do mar. O desenvolvimento de A. arenaria está intimamente relacionado com a variação topográfica da área de estudo. Densas populações de A. arenaria enriquecem o solo através do aumento de matéria orgânica sob sua cobertura proveniente de suas folhas senescentes e, conseqüentemente, potencializa o acúmulo de nutrientes caracterizando um microclima que pode colaborar no estabelecimento de outras espécies.Palavras-chave: biomassa, Allagoptera arenaria, restinga, Rio de Janeiro. INTRODUÇÃOOs ecossistemas de restinga caracterizam-se por solos arenosos, pobres em argilas e matéria orgânica, baixa capacidade de reter água e nutrientes e por uma grande proporção da entrada anual de nutrientes sob a forma do salsugem (van der Valk, 1974; Hay e Lacerda, 1984).

“…Groundwater response to recharge is different in different slack types (Lammerts et al 2001) and lags between rainfall and groundwater level change in some systems can be 4-7 months (Jones et al 2006). Groundwater table variations determine the abundance of many slack species, in particular in wet (humid) slacks (Willis et al 1959a;Willis et al 1959b). Seasonality is also important, with spring water levels controlling the breeding success of European Priority species.…”

Modelling small groundwater systems: experiences from the Braunton Burrows and Ainsdale coastal dune systems, UK

Coastal dunes are delicate systems that are under threat from a variety of human and natural influences. Groundwater modelling can provide a better understanding of how these systems operate and can be a useful tool towards the effective management of a coastal dune system, e.g. by identifying strategically important locations for flora and fauna and guiding the planning of management operations through predicting impacts from climatic change, sea level rise and land use management. Most dune systems are small, typically of the size 10-100 km 2 , compared with inland groundwater systems. Applying conventional groundwater modelling approaches to these small systems presents a number of challenges due to the local scale of the system and the fact that the system boundaries (sea, drains, ponds etc.) are close to the main body of the aquifer. In this paper, two case studies will be presented using different modelling approaches to understand the groundwater balance in two dune systems in the UK. The studies demonstrate that, although conventional hydraulic models can describe the general system behaviour, a fuller understanding of the recharge mechanisms and system boundaries is needed to represent adequately system dynamics of small groundwater systems.
