The fouling organisms at Songkhla Port were investigated from November 2011 to December 2012. Samples were collected using PVC panels (10 cm x 20 cm) submerged for one-month and three-month periods. Analysis of fouling panels was carried out using PhotoGrid software. In addition to slime and silt, three types of fouling organisms, namely encrusting bryozoa, barnacles and calcareous polychaetes, were observed on the submerged PVC panels. Calcareous polychaetes and molluscs were the most diverse groups (ten species) on panels that were submerged for one-month and three-month periods. Barnacles (Balanus spp.) were most abundant on panels submerged for three-month periods, while calcareous polychaetes dominated one-month panels. The dominant species of mollusc was the mussel Brachidontes sp. The major polychaetes identified were Ficopomatus macrodon, F. enigmaticus and Hydroides norvegicus. A highlight of this study was the first record of the Caribbean tubeworm Hydroides sanctaecrucis in Thailand, which has previously invaded and established in Australian waters through hull fouling.

This is the first record of Eleocharis mutata in Florida, and the second record in the continental USA, suggesting a potential natural range expansion of this species from the Caribbean region. A key to species of Eleocharis subg. Limnochloa in Florida is included, along with a site description of the occurrence, visual aids for identification, and a brief discussion of nativity.

Mexican Species

AbstractMillipede diversity in tropical regions, and in Mexico in particular, is still mostly unknown. A modest but recurrent source of new Mexican species is the colonization of exotic species, due to human activity. The invasive speciesCylindrodesmus hirsutusPocock, 1889 has spread from its area of origin in Indonesia or Melanesia and become a virtually pantropical species. Although long known from South and Central America, reports from the Caribbean are sparse and limited to some eastern islands and southern Central America. On 9 March 2016, two adult specimens were found on Cozumel Island, Quintana Roo, in an area of medium semideciduous tropical forest. This paper comprises the first record of this species from Mexico and the northern Caribbean. Given the intense commercial activity in the region, the presence of more populations both in Cozumel Island and in the mainland coast is highly probable.

Gall Crabs

Most of the diverse groups of crustaceans associated with scleractinian and fire corals form symbiotic relationship with their coral hosts. Coral-associated barnacles include species from the orders Acrothoracica and Thoracica. Most of the coral-associated barnacles belong to the family Pyrgomatidae in Thoracica. Within Pyrgomatidae, the subfamily Ceratoconchinae contains mostly extant species and is present from Florida through the Caribbean to Brazilian waters. The subfamily Megatrematinae has lower species diversity and has a cosmopolitan distribution (except the Eastern Pacific). The Pyrgomatinae are the most species-rich subfamily and distributed only in Indo-West Pacific waters. Host usage of pyrgomatinid barnacles varies spatially, probably related to coral host diversity. Copepods are the most common and most abundant coral-associated crustaceans, often associated with scleractinian, gorgonian, and alcyonacean corals. More than 90% of coral-associated copepods are endemic to the Indo-West Pacific. In contrast, only a few species (<10%) have been discovered from the Atlantic due to several historical perturbations reducing the diversity of their coral hosts. The communities of coral-associated copepods thus show dramatic differences between geographic regions, notably between the Indian, Pacific, and Atlantic Oceans. Brachyurans of the family Cryptochiridae (gall crabs) are obligate associates or parasites, of scleractinian coral hosts in tropical and subtropical seas, being a monophyletic group of only 52 species, from the intertidal to the deep sea (to 512 m) habitats with most (46) recorded in the seas of the tropical Indo-West Pacific and none being cosmopolitan. Atlantic species of Cryptochiridae, apparently not phylogenetically related, display less strict host specificity than their Indo-West Pacific counterparts. Current phylogenetic understandings of the group remain preliminary, while one consistent Indo-West Pacific clade reflects rapid species diversification during the last ~15 million years.

The arrival of Christopher Columbus in the northern Caribbean with three Spanish ships in October 1492 marked the beginning of continuing European contact with the Americas. With his second voyage of 1493 permanent European occupation of the Caribbean began, with enormous consequences for the peoples and ecology of the region. Failing to encounter the wealthy trading societies that Columbus had hoped to find by reaching Asia, Europeans in the Caribbean soon realized that they would have to involve themselves directly in organizing profitable enterprises. Gold mining in the northern islands and pearl fishing in the islands off the coast of Tierra Firme (present-day Venezuela) for some years proved enormously profitable but depended on Spaniards’ ability to exploit indigenous labor on a large scale. The imposition of the Spanish encomienda system, which required indigenous communities to provide labor for mining and commercial agriculture, and the large-scale capture and transportation of Native Americans from one locale to another wrought havoc among the indigenous peoples of the Caribbean and circum-Caribbean, resulting in high mortality and flight. Spaniards in the islands soon sought to supplement indigenous labor by importing African slaves who, in the early 16th century, became a significant if not always easily controlled presence in the region. From the earliest years the Spanish Caribbean was a complex, dynamic, and volatile region characterized by extensive interaction and conflict among diverse groups of people and by rapid economic and institutional development. Although the islands became the launching grounds for subsequent Spanish moves to the nearby mainland, throughout the 16th century and beyond they played a crucial role in sustaining Spain’s overseas empire and integrating it into the larger Atlantic system.

Mass Stranding

The pygmy killer whale (Feresa attenuata) is an offshore, tropical and subtropical delphinid found in the Atlantic, Indian and Pacific Oceans. The species has only recently been studied, mostly from specimens collected from strandings. While over 52 reports exist for the Atlantic Ocean, only one record exists for the Caribbean Sea. A new record of a mass stranding of pygmy killer whales from the British Virgin Islands is documented and the pathology and life history of the specimens is described, associating the stranding process with the meteorological and oceanographic disturbance of Hurricane Marilyn, which devastated the Virgin Islands a day prior to the stranding. This stranding event constitutes the sixth known mass stranding for the species worldwide, the first record for pygmy killer whales for the northeastern Caribbean and the second for the entire Caribbean Sea.

Abstract In this study, the seasonal flight activity of the Phlaeothripidae (Thysanoptera) species was studied by using suction trap, in South-East Hungary, in the years 2000 and 2004 from April to October. The flight period of two dominant species, namely Haplothrips angusticornis Priesner and Haplothrips aculeatus Fabricius (Thysanoptera: Phlaeothripidae), was observed in high number in Europe. Also, it was the first record of mass flight observation of H. angusticornis. In addition, the effect of meteorological factors, such as temperature, sunshine duration, relative humidity, air pressure, and their influences, were evaluated.
