The beetles of Martinique, Lesser Antilles (Insecta: Coleoptera); diversity and distributions

This paper summarizes the published information on the beetle fauna of the island of Martinique, in the Lesser Antilles. The fauna is known to contain 42 families, with 201 genera, and 270 species. The families with the largest numbers of species are Cerambycidae (57), Curculionidae (43), Scarabaeidae (42), Tenebrionidae (18), and Staphylinidae (17). At least 15species (5.5%) were probably accidentally introduced to the island by human activities. Forty six species (17.0%) are endemic (restricted) to the island and likely speciated on the island. Sixty seven species (24.8%) are shared only with other islands of the Lesser Antilles (Lesser Antillean endemics), and 26 species (9.6%) are more widespread Antilles endemics. The remaining 116 species (42.8%) in the fauna are otherwise mostly widely distributed in the Antilles and the Neotropical Region. The Martinique beetle fauna has mostly originated elsewhere than on Martinique and is largely an immigrant fauna from other islands of the West Indies or the continental Neotropics. The numbers of Martinique species shared with other larger islands of the Lesser Antilles are (north to south) Montserrat (73), Guadeloupe (175), Dominica (98), St. Lucia (68), St. Vincent (93), and Grenada (88). Undoubtedly, the real number of species on Martinique is much higher than now reported and may actually be around 1600 or more species

SPATIAL ANALYSIS AS TOOL FOR SENSITIVITY ASSESSMENT OF SEA LEVEL RISE IMPACTS ON MARTINIQUE

Sea level in the Caribbean region is expected to rise approximately10-20 cm by 2025. In some areas of Martinique coastal erosion and saltwater intrusion are already a severe problem. Because the island has a mountainous character, the majority of its settlements are situated along the coast almost at sea level. Considerations and strategies for dealing with potential sea level rise and its consequences for Martinique do not exist. This part of a detailed case study concentrates on the evaluation of sea level rise impacts on Martinique. It is going to test the suitability of spatial data for impact scenarios at a regional scale. Also, it conceptualises the possible effects of sea level rise on the island for future regional planning purposes. An elevation model is created that visualises the low-lying coastal areas and a second model evaluates the sensitivity of each coastal segment to erosion, flooding and inundation. The resulting map distinguishes between coastal parts at high, medium, or low risk to sea level rise impacts. Results show that nearly three quarters of the Martinique coast are highly sensitive to flooding and erosion.Caribbean, Lesser Antilles, Regional Planning, GIS, Climate Change, Coastal Change, Erosion, Inundation

Mamey (Mammea americana L.) in Martinique Island : un patrimonio para ser valorizados

Introduction. Mamey (Mammea americana L., Clusiaceae) was present in Martini-que before the Spanish colonization. Its distribution area includes tropical America and the Carib-bean. A significant phenotypical diversity is observed on the island, with fruits of very uneven quality as well as various agronomic, pomological and biochemical characteristics. The aim of our work was to localize, identify and characterize trees considered of superior quality. Materials and methods. A survey carried out between April and September 2005 allowed the selection of 10 trees renowned by the people as bearing high-quality fruits. These fruits present a small number of seeds and nonadhesive pulp, and develop a sweet taste as well as a strong flavor. During the year 2006, pomological description and biochemical analysis (total soluble solids and total titrable acidity) were carried out on the fruits. Results and discussion. The biometric and biochemical characteristics measured were generally better than those cited in the literature. Some accessions stand out and present great assets for their promotion for the fresh market as well as for processing. Moreover, some tendencies emerged from the variability observed for a few characters: thus, the variability of the biochemical characteristics measured within one accession, as well as between accessions originating from the same land, is low. It is null for the seed adhesion to the pulp for fruits belonging to the same accession. Conclusion and perspectives. Our work is one of the first relating to identification and characterization of phenotypical diversity of the M. americana L. species, especially in Martinique Island. Our results are likely to pro-mote the development of a diversification network. Some highlighted trends suggest new research to be able to distinguish the role of the environmental versus genetic components in the performance of the phenotypes observed

The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera) : diversity and distribution

The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation

Biological control in French Guiana, Guadeloupe and Martinique

Several biological control agents have been introduced successfully in Guyana, and / or Guadeloupe and Martinique: three tachinid dipterans and one hymenopteran for control of sugarcane borers, a ladybird and a hymenopteran parasitoid against the pink hibiscus mealybug, a hymenopteran parasitoid to control Asian citrus psyllid, another hymenopteran parasitoid against citrus blackfly, and a hymenopteran parasitoid for control of fruit flies. Mass rearings of a lacewing and a Trichogramma egg parasitoid are being implemented in Martinique for augmentative biocontrol. Use of native natural enemies in conservation biocontrol projects is being initiated in several crops, after a period of intensive prospecting for natural enemies. A recently started project in French Guiana aims at control of the mango mealybug by introducing two exotic parasitoids

Grenada Carriacou Petite Martinique

The Eastern Caribbean Seascape is an arc of islands linked through diverse coral reef ecosystems, oceanic currents, migratory pathways and a rich cultural heritage. The Eastern Caribbean Coral Reef Report Cards are a series of individual reports for the6 participating countries and provide an easy-to-understand summary of the state of the region's marine resources. The Report Cards collate data from 277 comparable coral reef surveys and map in detail 383 km2 of coral reefs, 19 km2 of mangrove, 286 km2 of seagrass, 44 designated and 50 proposed Marine Managed Areas (MMA). The Report Cards provide an initial baseline on the current state of the reef and identify gaps. Reporting this type of information will help track progress in protecting reefs and inform future monitoring and management. The vision is to produce report cards every 2 years and share data through the CaribNode regional spatial data platform. Future report cards will include key socioeconomic and management effectiveness information. Each Report Card includes information on:Key Habitats (location and extent of coral, mangrove, seagrass)Reef Health Index (a measure of the health of four key coral reef indicators)Marine Managed Areas (size and location of designated and proposed areas
