| The spionid polychaete Boccardia proboscidea Hartman, 1940 is a tube-dweller and shell/stone-borer widely occurring in temperate waters across the world and considered invasive in many areas. It was originally described from California, USA, and later reported from Pacific Canada, the Asian Pacific, Australia, New Zealand, Argentina, South Africa, and northern Europe. The Bayesian inference analysis of sequence data of three gene fragments (836 bp in total) of the mitochondrial 16S rDNA, nuclear 28S rDNA, and Historie 3 has shown that individuals from the Pacific coasts of Canada and the USA, Argentina, Australia, South Africa, the United Kingdom, and Mediterranean France were genetically very similar (maximal average p-distance value, 0.49%, was between... |

| Density, taxonomic composition at higher taxon level and vertical distribution of benthic macrofaunal communities and sediment characteristics (pore water, nitrogen, organic carbon, sulfur, C/N ratio, n-alcohol biomarkers) were examined at three deep sites on the Congo-Gabon continental margin. This study was part of the multidisciplinary BIOZAIRE project that aimed at studying the deep benthic ecosystems in the Gulf of Guinea. Sampling of macrofaunal communities and of sediment was conducted during three cruises (January 2001, December 2001 and December 2003) at two downslope sites (4000 m depth), one located near the Congo submarine channel (15 km in the south) and the other one far from the channel (150km in the South). The third area located 8 km north... |

| Marine debris is commonly observed everywhere in the oceans. Litter enters the seas from both land-based sources, from ships and other installations at sea, from point and diffuse sources, and can travel long distances before being stranded. Plastics typically constitute the most important part of marine litter sometimes accounting for up to 100 % of floating litter. On beaches, most studies have demonstrated densities in the 1 item m−2 range except for very high concentrations because of local conditions, after typhoons or flooding events. Floating marine debris ranges from 0 to beyond 600 items km−2. On the sea bed, the abundance of plastic debris is very dependent on location, with densities ranging from 0 to >7700 items km−2, mainly in coastal... |

| A third coronary artery (TCA) has been defined as a direct branch from the right aortic sinus (RAS) that contributes to the vascularization of the infundibulum of the right ventricle (RV). The distribution of this artery may be important in surgical procedures and in understanding the extent and progression of acute myocardial infarction. Its reported prevalence however shows ethnic disparity. The aim of the study was describe the prevalence and distribution of the third coronary artery in a Kenyan population. 148 cadaveric and postmortem human adult hearts obtained from the Department of Human Anatomy, University of Nairobi, and the Chiromo and Nairobi city mortuaries were used after an ethical approval. The hearts were studied by gross dissection for the... |

| The aim of the present study was to investigate the presence of Trypanosoma cruzi in the heart, liver, lung, and kidneys, using hemoculture and PCR analysis, of mice infected with different parasite strains during the acute and chronic phases of infection. Parasitemia curves revealed strain-specific biological behaviors. For the Y and JLP strains, the acute phase of infection started at days six and ten post-infection, parasitemia peaked at days seven and 15 post-infection, the chronic phase started at days nine and 28 post-infection, and animals started dying at days 19 and 120 post-infection, respectively. When the two strains were compared, the JLP strain exhibited reduced and slower replication rates associated with a delayed peak of parasitism and... |

| Six species of bats have been previously reported from the Antillean island of Saint Martin/Sint Maarten- Artibeus jamaicensis, Brachyphylla cavernarum, Molossus molossus, Tadarida brasiliensis, Noctilio leporinus, and Myotis nigricans nesopolus. Our field research reported herein documents an additional three species of bats from the island for the first time- Monophyllus plethodon, Ardops nichollsi, and Natalus stramineus. Re-examination of the single voucher of Myotis nigricans nesopolus has led us to exclude this species from the fauna of Saint Martin/Sint Maarten. Based on our field research and the study of specimens housed in museum collections, we present information on the eight species of bats that we have documented as occurring on Saint... |

| As a result of a systematic review of nectar feeding bats in the genus Lonchophylla (Phyllostomidae) deposited in the scientific collections of the Instituto de Ciencias Naturales (ICN) in Bogotá and the Museo de Historia Natural of the Universidad del Cauca (MHNUC) in Popayán, we report range extensions for three Colombian species. Lonchophylla cadenai is reported from Pueblo Rico, Risaralda, representing an increase in both altitudinal and latitudinal ranges; L. handleyi is reported from Cueva de los Guácharos, Huila, confirming the presence of this taxon in Colombia and representing its northernmost known record; and L. pattoni is reported from Leticia, Amazonas, which constitutes the third known collecting locality for this taxon and represents the... |
