Abstract
|
Possible contaminants produced by the Petroleos Mexicanos (PEMEX) marine oil complex in the vicinity of the Cayo Arcas (Mexico) coral reef ecosystem were evaluated by analyzing sediments and sea water for hydrocarbons and metal elements. We found that the concentrations of aliphatic hydrocarbons in the sea water were generally low, with the highest values detected near the oil station; the concentration of polycyclic aromatic hydrocarbons (PAHs) was generally below the detection limit. The hydrocarbons found in the sediments seem to have a pyrogenic origin, and were probably produced by marine traffic in the study area. The total PAH concentration did not exceed the NOAA criteria, although levels of some individual PAHs did. The only metal detected in the sea water at high concentrations was nickel. The Ni/V ratio in the sediments indicates the contribution of crude oil to the system. The high content of Ni and Zn was attributed to the ballast waters from the oil tankers that load at the station's monobuoys. The presence of fine sediments that commonly originate from terrestrial ecosystems supported this assumption.

Abstract
|
The corals occurring in bays adjacent to mouths of rivers in Western Province, Solomon Islands, are being studied to quantify the effects of runoff associated with logging on coral reefs. The 5-year study aims to identify any effects of runoff on fringing coral reefs by comparing abundance, diversity, survival and recruitment of corals adjacent to ,
actively logged, previously logged and unlogged catchments on each of 2 islands. A pilot study comparing diversity and abundance of corals adjacent to actively logged and unlogged catchments indicated that effects of runoff on corals did not always conform to predictions, and differed between islands. For example, there was more dead coral
adjacent to logged catchments at Vangunu Island, whereas at Kolombangara Island, more live coral occurred adjacent to actively logged catchments. The comparison of bays adjacent to actively logged, previously logged and unlogged catchments over 5 years is expected to provide a robust test of any effects of runoff on diversity and abundance of
corals, whilst also testing for recovery from any such impacts.

Abstract
|
It is hypothesized that monsoon forcing interacts with antecedent reef platform structure to produce characteristic growth configurations and predictable reef morphologies in Maldives. The hypothesis is being tested by the classification of LANDSAT-7 ETM+ imagery of all reefs along the N-S and E-W axis of the archipelago, and the
calculation of morphometric indices. Well-defined gradients in monsoon forcing and antecedent platform structure are quantified along the same dimensions, and statistically related to the morphometrics. Here, it is reported the theoretical and analytical basis of the study, and present preliminary results that demonstrate the ability of remotely
sensed imagery to quantify large (I.5-5x) asymmetries in lateral reef growth, which correspond to differences of similar magnitude in the wave energy generated by the NE and SW monsoons.

Abstract
|
The unprecedented coral bleaching in the Maldives in 1998 resulted in extensive mortality of reef invertebrates with symbiotic algae, especially reef building corals. The percentage of living coral cover declined markedly immediately after the bleaching event, from around 30– 60% pre-bleaching to 0–5% post-bleaching for shallow reef-flat areas (Allison, 1999). Fast-growing branching corals, particularly Acropora spp., were more susceptible to bleaching, and, as a consequence, suffered greater mortality than slow-growing massive corals. The ultimate consequences of the 1998 bleaching event will not be fully understood for some time, possibly for decades. However, it is clear that reefs will be
modified as a result of this bleaching event. In the short
term (<5 years), coral reefs that were formerly dominated
by branching species will now be dominated by nonliving
substrate that support a few surviving colonies of
massive species. The consequences of bleaching for the
reef framework will largely depend on the transport and
fate of CaCO3 fragments. Where reef disturbance is
severe, boring and grazing organisms may remove
CaCO3 faster than primary frame-builders can accrete
it. Such biogenic processes will determine whether the
structural integrity of the reef will remain intact.
This study was conducted to investigate the processes
of reef recovery after the bleaching event in 1998. The primary objectives of this study were to identify the
main contributing groups of reef boring organisms and
their relative rates of bioerosion.

Abstract
|
In 2003 and 2005, studies were carried out on the density of small coral colonies (less than 10 cm) on three reefs in the Mombasa Marine National Park and Reserve on the southern fringing reef system of Kenya, and on three reefs in the Kiunga Marine National Reserve in the north of the country. All the study sites were impacted by a major coral bleaching event in 1998. A total of 28 coral genera from 12 families were recorded, of which 17 genera were recorded on both northern and southern sites. Two or three genera of corals contributed 50-60% of all small colonies in both regions, with Porites, Coscinarea and Pocillopora the main contributors of small colonies in Kiunga, and Pocillopora being the most abundant genus of small corals in Mombasa in both years. The densities of small colonies were lowest at the northern sites, and small colonies of genera of corals that suffered from high bleaching and mortality during the El Niño Southern
Oscillation in 1998 were less abundant in the north. These northern reefs are relatively isolated from sources of coral larvae from reefs in the south, and are seasonally influenced by nutrient-rich, cooler water due to the influence of the Somali Current and the northeast monsoon winds. The
data presented here support our preliminary assessment that these northern reefs are less likely to recover by natural recruitment. These reefs are therefore more vulnerable to environmental perturbation such as the conditions that elicited coral bleaching on the study reefs in 1998.

Abstract
|
Managing the effects of anthropogenic disturbance on coral reefs is highly dependant on effective strategies to assess degradation and recovery. We used five years of field data in the US Virgin Islands to investigate coral reef response to a potential gradient of stress. We found that the prevalence of old partial mortality, bleaching, and all forms of coral health impairment (a novel category) increased with nearshore anthropogenic processes, such as a five-fold higher rate of clay and silt sedimentation. Other patterns of coral health, such as recent partial mortality, other diseases, and benthic cover, did not respond to this potential gradient of stress or their response could not be resolved at the frequency or scale of monitoring. We suggest that persistent signs of disturbance are more useful to short-term, non-intensive (annual) coral reef assessments, but more intensive (semi-annual) assessments are necessary to resolve patterns of transient signs of coral health impairment.

Abstract
|
1. Seahorses (Hippocampus spp.), many of which are listed as Vulnerable or Endangered on the IUCN Red List, are traded worldwide as souvenirs, aquarium fish and, primarily, for use in traditional medicines. Given concern over the sustainability of this trade, the genus was added to Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in May 2004.
2. This paper reports findings of the first ever survey of seahorse trade in Africa, conducted in Kenya and Tanzania in May and June 2000.
3. Seahorse trade in Kenya was found to be negligible, with approximately 10 live seahorses exported as aquarium fish annually. Until 1998, however, Kenya may have imported somewhere from 1 to 2.3 t of dried seahorses annually from Tanzania for re-export to Asian medicine markets. Seahorse trade in Tanzania remained substantial, with at least 630–930 kg of dried seahorse exported directly to Asia each year.
4. Accounts of declines in seahorse availability and seahorse size, although few in number, could be early warning signs that wild populations are suffering, at least locally. Close monitoring of future developments in the trade will be essential to allow for timely conservation action as and when necessary, and would contribute to our understanding of the ecological and economical implications of small-scale, non-food fisheries.

Abstract
|
Most countries in the Western Indian Ocean (WIO) have
one or more marine protected areas (MPAs) dedicated
to the protection and maintenance of biological
diversity, natural resources and cultural heritage values.
Of these, two (Greater St Lucia Wetlands Park and
Aldabra Atoll) are listed as World Heritage sites under
the World Heritage Convention, and another three
(Malindi-Watamu and Kiunga-Dodori in Kenya, and
Mananara-Nord in Madagascar) are listed as Biosphere
Reserves under the UNESCO Man and Biosphere
Programme in recognition of their global value.
Experience has shown that it is not simply enough to
declare or legally gazette an area as an MPA, although
this is a vitally important step. The long-term success of
an MPA depends on effective management combined
with demonstration of its usefulness and
appropriateness as a conservation and management
tool within its local and national context.
Management effectiveness is the degree to which a
protected area is achieving its objectives and goals.
The main aim of assessing management effectiveness is
to improve performance of the MPA, through adaptive
management – adjusting management actions on the
basis of lessons learnt over time. Assessment should be
seen as a normal and essential component of the
process of MPA management.
It is not only important for looking for problems and
finding solutions, but it is also a way of identifying what
is working well, so that a learning environment is
created. A learning environment is one that
encourages the sharing of knowledge, skills and
experiences both within and outside an organisation, so
that lessons learnt are not lost and mistakes are not
repeated. A learning environment does not focus on
what was successful and what failed, but on the
‘lessons learnt’ and how others might benefit from these
experiences.

Abstract
|
Coral reefs in shallow-water environments (<30 m) are in decline due to local and global anthropogenic stresses. This has led to renewed interest in the ‘deep reef refugia’ hypothesis (DRRH), which stipulates that deep reef areas (1) are protected or dampened from disturbances that affect shallow reef areas and (2) can provide a viable reproductive source for shallow reef areas following disturbance. Using the Caribbean as an example, the assumptions of this hypothesis were explored by reviewing the literature for scleractinian corals—the reef framework builders on tropical reefs. Although there is evidence to support that deep reefs (>30 m) can escape the direct effects of storm-induced waves and thermal bleaching events, deep reefs are certainly not immune to disturbance. Additionally, the potential of deep reefs to provide propagules for shallow reef areas seems limited to ‘depth-generalist’ coral species, which constitute only ~25% of the total coral biodiversity. Larval connectivity between shallow and deep populations of these species may be further limited due to specific life history traits (e.g., brooding reproductive strategy and vertical symbiont acquisition mode). This review exposes how little is known about deep reefs and coral reproduction over depth. Hence, a series of urgent research priorities are proposed to determine the extent to which deep reefs may act as a refuge in the face of global reef decline.

Abstract
|
As live coral cover continues to decline in the Florida Keys, it becomes increasingly important not only to determine the location and abundance of live coral remaining, but also to understand why certain areas possess higher coral cover than others. At present, coral cover tends to be highest at shallow inshore patch reefs. Our study has two objectives: 1) to determine, to the full extent visible by satellite imagery, the number and characteristics of patch reefs that could be recognized using IKONOS imagery; and 2) to test the assumption that various morphological groups of patch reefs occupy distinct cross-shelf zones in the Lower Keys. Two previous survey efforts using aerial imagery and reported 420 and 750 patch reefs, respectively, from Big Pine to the Marquesas Keys. By performing a visual assessment on IKONOS satellite imagery, we were able to delineate 2,251 patch reefs for this region. These patch reefs vary in their overall morphology (i.e., shape) and are spatially distributed in several cross-shelf bands. Patch reef classes identified were Aggregate, Atom, Colony, Crescent and Dome. Aggregate patch reefs are very numerous, relatively small, and dominantly located either shallow-midshelf or offshore. Dome, Colony and Crescent patch reefs are larger in area and are most common in the shallow-midshelf or offshore zones. This study represents an important first step in understanding the factors that may be controlling the distribution and shape of patch reefs along the Florida Keys Reef Tract and, subsequently, relating this to living coral cover on modern reefs.

Abstract
|
Marine protected areas (MPAs) are reported
to be effective means of managing coral reefs;
consequently, many developing countries have
established MPA programs. However, whether these
MPAs are successful measured against their stated
objectives has rarely been assessed. An assessment of
the management effectiveness of Kenya’s youngest
MPA, the Mombasa Marine National park and reserve,
was conducted using biophysical, socio-economic and
governance indicators including coral reef health, socioeconomic
welfare and participation of stakeholders and
the level of institutional support for the management of
the MPA. Rates of recovery of coral cover and finfish
biomass were higher in the marine park (no-take area)
than in the marine reserve (restricted fishing zone)
indicating that the marine park is making some progress
towards meeting the stated objective of biodiversity
conservation. The marine reserve however, is not as
effective in meeting the objective of sustainable
utilization, because both coral cover and finfish biomass
have not shown any appreciable increase after
protection. The MPA and local communities are highly
dependent on tourism and their financial stability was
negatively impacted by factors external to the
management of the MPA including ethnic violence and
international terrorism. In addition the 1998 bleaching
event caused high mortality of corals in the MPA; while
the park is showing signs of recovery the reserve is not.
Finfish biomass did not show marked changes after the
bleaching. The MPA is adequately supported with
national legislation, financial support and a management
plan. However administrative instability within the
management authority (the Kenya Wildlife Service) and
conflicts of mandate with other national institutions such
as Fisheries department has constrained the ability of the
MPA to implement management initiatives.

Abstract
|
This paper investigates how sea tenure institutions in the Roviana Lagoon, Solomon Islands, mediate among population, consumption, and the environment. The focus is on explaining how growth in population and consumption alter sea tenure regimes, and the factors that shape either their institutional robustness or vulnerability. The paper also addresses the regional differences among sea tenure institutional arrangements, the processes that are producing them, and the social and environmental outcomes of these institutions as they engage external forces and internal changes. A major question is how existing forms of sea tenure respond comparatively when faced with parallel demographic and economic transformations? Two villages representing different sea tenure arrangements within the Roviana Lagoon are compared. Results show that inhabitants in these villages perceive their systems of sea tenure governance similarly; yet their managerial responses to changes brought about by growth in population and consumption differ, and the responses produce contrasting environmental effects.

Abstract
|
Surveys were completed on Tutuila Island, American Samoa, to characterize reef development and assess the impacts of non-point source pollution on adjacent coral reefs at six sites. Multivariate analyses of benthic and coral community data found similar modern reef development at three locations; Aoa, Alofau, and Leone. These sites are situated in isolated bays with gentle sloping foundations. Aoa reefs had the highest estimates of crustose coralline algae cover and coral species richness, while Leone and Alofau showed high abundances of macroalgae and Porites corals. Aoa has the largest reef flat between watershed discharge and the reef slope, and the lowest human population density. Masefau and Fagaalu have a different geomorphology consisting of cemented staghorn coral fragments and steep slopes, however, benthic and coral communities were not similar. Benthic data suggest Fagaalu is heavily impacted compared with all other sites. Reef communities were assessed as bio-criteria indicators for waterbody health, using the EPA aquatic life use support designations of (1) fully supportive, (2) partially supportive, and (3) non-supportive for aquatic life. All sites resulted in a partially supportive ranking except Fagaalu, which was non-supportive. The results of this rapid assessment based upon relative benthic community measures are less desirable than long-term dataset analyses from monitoring programs, however it fills an important role for regulatory agencies required to report annual waterbody assessments. Future monitoring sites should be established to increase the number of replicates within each geological and physical setting to allow for meaningful comparisons along a gradient of hypothesized pollution levels.

Abstract
|
Although invasive species are widely recognized as a major threat to marine biodiversity, there has been no quantitative global assessment of their impacts and routes of introduction. Here, we report initial results from the first such global assessment. Drawing from over 350 databases and other sources, we synthesized information on 329 marine invasive species, including their distribution, impacts on biodiversity, and introduction
pathways. Initial analyses show that only 16% of marine ecoregions have no reported marine invasions, and even that figure may be inflated due to under-reporting. International shipping, followed by aquaculture, represent the major means of introduction. Our geographically referenced and publicly available database provides a framework that can be used to highlight the invasive taxa that are most threatening, as well as to prioritize the invasion pathways that pose the greatest threat.

Abstract
|
A long term integrated and participatory
conservation programme in northern Tanzania has
resulted in the establishment of six collaborative
management areas (CMAs), which were zoned for
multiple uses and include no-take zones. Monitoring of
these areas was initiated bi-annually in 1996 and has
continued to the present. Trained community members
conduct the monitoring and to ensure quality of the
collected data bi-annual calibration exercises are
conducted. The following parameters are measured:
benthic substrate (live, dead, or bleached coral, macroalgae,
soft coral, sponge, seagrass and various abiotic
parameters including rubble), sedentary macroinvertebrates
(sea-urchins, sea-cucumbers, starfish, giant
clams, octopus, crayfish, crown-of-thorns) and fish
(generally identified at the family level, covering 13
families). Analyses to date have shown increases in fish
densities and live coral cover on the closed reefs since
management and enforcement was implemented in 1996.
However, the pattern of recovery in coral cover was
complicated by the coral-bleaching event in 1998. In
addition, coral cover was affected by an outbreak of a
coral disease along the east African coast in 2002/2003,
which affected 4 genera, including Montipora and
Astreopora. The results indicate that recovery in closed
reefs from bleaching and the disease was greater,
supporting improved resilience. Further, coral cover has
increased through the CMAs since destructive fishing
practices, primarily dynamite fishing and beach seining,
have been greatly curtailed. The results demonstrate the
positive impacts of protected areas for managing coral
reef resources, and the effectiveness of community
participation in long term monitoring.

Abstract
|
Higher biodiversity is usually loosely
associated with good quality systems relative to human
use. But does biodiversity really have an effect on the
quality of ecosystem services, such as coral reef fisheries
yield? To address this question, we built an individualbased
model of a hypothetical coral reef ecosystem
wherein fish and invertebrate diversity is interpreted as
individual variability among a set of static traits.
The model is composed of 2 interacting layers: a
cellular-automata reef bottom and an individual-based
simulation of fishes, invertebrates and fishers, which
interact with each other. It incorporates foraging,
predation, and competition among fish agents;
movement, growth, reproduction, and mutation for each
fish agent; and fishing for fisher agents.
The model was first run through an evolutionary
phase wherein initial parameter values were fed into the
model and then run for 52,000 time steps, equivalent to
1,000 years, to generate a system of diverse fish and
invertebrate agents. In the ecological phase, mutation
was turned off and fisher agents were introduced to
selectively fish high biomass cells until the system was
depleted. Several simulations for the ecological phase
were run at different initial levels of diversity and fishing
pressure.
Results showed that the effect of diversity on
cumulative total fish catch was most evident in the runs
wherein the starting diversity was reduced to 1% of the
original number of unique agents generated through the
evolutionary phase. Above this, individual genotypic
variability had no significant effect on total fish catch.

Abstract
|
We propose a statistical approach based on multivariate analysis and general linear models to test the consequences of removal of reserve status from the Abore Reef fish assemblage of the Abore Reef reserve, New Caledonia. Consequences on fish density were examined at the level of fish assemblage, accounting for habitat. Fish counts and habitat-related information were collected before and after the removal of reserve status, both inside and outside the reserve. Species groups were constructed on the basis of additional information on behavioural characteristics and taxonomy. The impact of the removal of reserve status was assessed by using 2 habitat proxies corresponding to 2 spatial scales and by considering several criteria for grouping species. Habitat appeared to be a determining factor in explaining density variations. Significant positive effects were found for several species groups such as macrocarnivores, piscivores, herbivores, Lethrinidae and Siganidae. A counterintuitive negative effect was observed for Acanthuridae. No significant differences between the area which remained closed to fishing and the area open to fishing were found for the other species groups. The approach allows for a synoptic diagnosis of the impact of changes in reserve status at the fish assemblage level. It could be used to develop and select potential indicators for monitoring such impacts on fish assemblages in coral reef ecosystems and in other contexts.

Abstract
|
Many field experiments have tested for effects of competition in nature, but relatively few have used designs allowing simultaneous assessment of the influence of intra- and interspecific competition. Using a response surface design and a press manipulation of densities, we tested effects of competition within and between two species of coral reef fishes (Coryphopterus glaucofraneum and Gnatholepis thompsoni). By tracking individually tagged fishes, we showed that the per-capita effect of intraspecific competitors on individual growth was at least twice as great as the effect of interspecific competitors. Growth rate was better predicted by measures of density that incorporated body size, rather than numerical density, suggesting interference competition. Individuals of both species interacted aggressively with conspecifics at least twice as often as with heterospecifics. Individuals of both species also covered more area while foraging and spent less time in shelter when crowded than when at lower densities. In combination, these behaviours suggest that increased metabolic costs at high density contribute to competitive effects on growth. These competitive interactions occurred among adult fishes, so reduced growth may translate to reduced fecundity as well as reduced survival, and so contribute to population regulation.

Abstract
|
Earlier studies in the tropical Indo-Pacific have grossly underestimated the richness of macrofauna species at spatial scales relevant to conservation and management as a result of insufficient collecting and sorting effort. A massive collecting effort involving 400 day-persons at 42 discrete stations on a 295-km2 site on the west coast of New Caledonia, south-west Pacific, revealed 2738 species of marine molluscs. This is several times the number of species recorded from any area of comparable extension anywhere in the world. Spatial and habitat heterogeneity is high with 32% of the species collected at a single station. With 20% of the species represented by single specimens (0.4% of all catches), rare species make up a considerable proportion of the fauna. This justifies the parallel drawn between coral reefs and rain forests in terms of species diversity. The real richness of many soft-bodied marine taxa is probably underestimated, as evidenced by the fact that 28.5% of the mollusc species present at the study site are represented in the samples only by empty shells.

Abstract
|
Coastal populations in the Indian Ocean have been adversely affected by coral reef mortality resulting from
the bleaching event in 1998. Assessing the socioeconomic impacts focused on the two main coastal activities
in the region, tourism and fisheries. Anticipating the full impacts will be vital to enable these countries to
adapt and manage the situation. The study found, in many cases, the full impacts of the reef degradation are
still to be seen. The impacts are also variable across the region, as was the extent of the bleaching. Impacts
on fisheries will become apparent as changes occur to the reef structure. In places where the reef structure
breaks down, the reef fisheries could collapse, affecting millions of small-scale fishermen. The importance
of reef fisheries in terms of provision of food and employment was established. Tourism creates both direct
and indirect employment for these coastal populations and in many of these countries is an important source
of foreign income. The economic costs of the coral bleaching in the Maldives was estimated at US$3 million
in 1998-99, with welfare losses reaching US$63 million. Estimates of the financial cost of the bleaching in
Mombasa, should dissatisfied tourists not return, was estimated at US$13-$20 million, and in Zanzibar was
estimated at US$3-$5 million. Understanding and anticipating tourist behaviour will enable governments and
tourism boards to take timely precautions, changing marketing strategies and retaining their tourism industry.
The full socioeconomic impact of the bleaching will become apparent in the near future.

Close to half of the world’s poor people live in South Asia (UNICEF, 2001; Samarakoon, 2004). Ramachandran (2002) identified population growth, insufficient food production, and underdevelopment as the major problems in the region. Open access to the sea, poverty, and an increasing demand for fishery products has escalated pressure on coastal resources (e.g. James, 1994; Devaraj & Vivekanandan, 1999; Bhattacharya & Sarkar, 2003; Perera et al., this volume). For example, in India, the number of fishermen in coastal villages increased from two million to six million between 1980 and 1997 (Meenakumari, 2002). Moreover, growing commercial fleets operating in near-shore waters to supply expanding export markets cause habitat destruction and deprive local communities of fish products and a cheap source of nutrition (Jayashree & Arunachalam, 2000; Bavinck, 2003; Bhattacharya & Sarkar, 2003). About 10% and 15% of the total fish catches in India and Sri Lanka respectively are derived from coral reefs by small-scale fishermen (Wafar, 1986; Rajasuriya et al., 1995). Although this is a considerable proportion of the national fish catches, these statistics do not adequately illustrate the actual situation in many areas in the region where hundreds of thousands of poor people depend solely on the products of coral reefs for food and livelihood (e.g. Berg et al., 1998, Kannan et al., 2001; Shanthini et al., 2002; Hoon, 2003; Singh & Andrews, 2003; Whittingham, 2003; Patterson et al., this volume).
