Structural complexity plays a key role in the functioning of coral reef ecosystems. Reef-building corals are major contributors to this complexity, providing shelter and food for numerous invertebrates and fish species. Both structural complexity and shelter capacity of reefscapes are determined by several components such as spurs and grooves, slope, caves and holes, vegetation and coral colonies. Quantifying the shelter capacity from coral colonies to reefscapes is a fundamental step to estimating ecosystem potential to support biodiversity. Here, we applied underwater photogrammetry to quantify shelter volumes provided by individual coral colonies. Overall, 120 3D models of coral colonies from branching, massive, columnar and tabular growth forms were...

Application of spot data to a base-line ecological study of the mahakam delta mangroves (east kalimantan, indonesia)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Dutrieux, Eric; Denis, Jacques; Populus, Jacques.
The objective of this study is to explain the spatial and temporal distribution of the vegetal communities of the Mahakam delta, chiefly on the basis of its physical and chemical characteristics. The delta is at present subjected to intense oil exploitation, and it is necessary to describe the situation on the site and its natural evolution in arder to be able to evaluate the damage that accidentai oil spillage could cause. The authors provide elements to define the sensitive zones whose protection should be a matter of priority. SPOT imagery was chosen as the tool allowing such an approach on a delta measuring 1 500 km2 SPOT satellite images of the Mahakam delta show that different plant communities succeed one another bath in time and in space. The...
