The Use of Remote Sensing to Map and Monitor Coastal Dune Vegetation Change at Southampton, Ontario, Canada
Coastal dune ecosystems in the Great Lakes Basin are fragile, rare ecosystems that are under increasing threat due to anthropogenic and natural forces. The Chantry Dune system in Southampton, Ontario is one of five major dune systems along the eastern shores of Lake Huron. The dune complex provides …

Population Biology Of A Coastal Dune-Dwelling Spider (Arctosa Sanctaerosae) Along The Hurricane Disturbed Northern Gulf Of Mexico Coast
… In addition to anthropogenic disturbance to this coastal region, hurricanes are an additional and natural perturbation to the ecosystem. This habitat has seen a number of major tropical storms over the last decade and I have sought to explore the impact of habitat destruction and storm-induced …

An application of LIDAR to examine erosion in the southern Monterey Bay during the 1997-98 El Nino
… Geographic Information System (GIS) to quantify coastal changes to beaches and dunes in the Southern Monterey Bay region and to qualitatively assess the erosional impact of large storms on coastal dune areas. LIDAR provides a rapid and accurate survey technique to measure topographic elevation. A …

The ecological life history of the Cape Bulbul
… capensis was carried out in 20 hectares of coastal dune forest near Port Elizabeth, South Africa. Results from four years 1959 to 1962 are given in detail and only the number of breeding pairs present in 1958 have been used from observations that year. The Cape Bulbul is one of three closely …

Environmental Impacts on the Development and Dune Activity of Oxbow Lake along the Southwest Coast of Lake Michigan at Saugatuck, Michigan USA
Coastal dunes of Lake Michigan and corresponding down-wind lakes are studied for links between dune activity and climatic forcing; to date, little is certain about climate control on dune activity. By unveiling relationships between climate variables and dune activity, it becomes possible to …

A Checklist Assessment of Dune Vulnerability and Protection Measures in Wales U.K
… can quantitatively assess the vulnerability of a dune system and the effectiveness of protection measures. A checklist system has been devised that attempts to overcome this problem. The analysis consisted of assessing a series of 54 parameters which are organised into the following five …

Populations studies on two endemic taxa of southwestern Sardinia: Dianthus morisianus Vals. (Caryophyllaceae) and Anchusa littorea Moris (Boraginaceae)
In the Mediterranean region as elsewhere, intense coastal development has resulted in widespread modification of coastal ecosystems. Here, coastal sand dunes represent an extremely vulnerable habitat to many forms of disturbance, including those connected with recreational tourism which in recent …

Alongshore coupling of eco-geomorphological variables in a beach-dune system
ABSTRACT: Coastal dune systems are becoming increasingly vulnerable to erosion and washover due to sea-level rise and changes in storm activity with changing climate. The impact, however, is not consistent within and across coastal barriers and there is a need to examine the alongshore variability …

Durabilidade e módulo de elasticidade de misturas areia - cal - cinza volante
… sand with crushed stone. The selected soil was a coastal dune sand, cohesionless and with uniform gradation, in order to enhance the cementitious pozzolanic action of lime plus fly ash when mixed with water. Three mixtures with different proportions wers studied. The first mix had 83% dune sand, …

Modelización de la evolución morfodinámica de la duna de Valdevaqueros (t.m. Tarifa) mediante la aplicación de funciones empíricas ortogonales a corto, medio y largo plazo
… given rise to the transgressive Valdevaqueros dunefield. The dune advance has resulted in gradual invasion of the adjacent road and ecosystem. Despite restoration and control activities performed within the last decades, strong east winds have favoured dune destabilisation. The current work …

A study of forest ecosystem development
… Palmerston North on recently consolidated sand dunes (Cowie & Smith, 1958). Coastal dunes have been stabilised with marram grass and lupin and planted with P. radiata in successive stages, to prevent drifting over adjacent farmland. The district has a mean annual temperature of 12.3°C and an …
