The Fish Communities of a Coral Reef Transect!
As a contribution to the discussion on the causes of the high fish species diversity found on coral reefs, a coast-to-sea transect has been studied in the lagoon of Moorea Island (French Polynesia) in order to uncover the spatial scales at which recurrent assemblages (i.e., communities) can be identified . The transect was divided into 22 stations where fishes were sampled. According to the nul...
متن کاملComparison of functional and anatomical estimations of visual acuity in two species of coral reef fish.
The high-contrast, complex patterns typical of many reef fish serve several purposes, including providing disruptive camouflage and a basis for vision-based communication. In trying to understand the role of a specific pattern, it is important to first assess the extent to which an observer can resolve the pattern, itself determined, at least in part, by the observer's visual acuity. Here, we s...
متن کاملHydrodynamic Modelling of Coral Reefs:Ningaloo Reef-Western Australia
As with all coral reef systems, the ecology of Ningaloo Reef is closely linked to water circulation which transport and disperse key material such as nutrients and larvae. Circulation on coral reefs may be driven by a number of forcing mechanisms including waves, tides, wind, and buoyancy effects. Surface waves interacting with reefs have long been known to dominate the currents on many coral r...
متن کاملBIFURCATION ANALYSIS OF A DDE MODEL OF THE CORAL REEF
In this paper, first we discuss a local stability analysis of model was introduced by P. J. Mumby et. al. (2007), with $frac{gM^{2}}{M+T}$ as the functional response term. We conclude that the grazing intensity is the important parameter to control the existence or extinction of the coral reef. Next, we consider this model under the influence of the time delay as the bifurcat...
متن کاملBiodiversity and distribution patterns of coral reef ecosystems in ROPME Sea Area (Inner part: Persian Gulf -Iranian waters)
The Persian Gulf is northern part of the ROPME Sea Area (RSA), and is semi-enclosed shallow sea which located in subtropical climate. Measuring is 1000km in length, varying in width 60-340km, and average depth is about 35m and maximum depth is 105m. This research was carried out during 2005-2010 for reviewing the corals status and determination of coral reef habitats distribution in the Persian...
