The composition of marine macroinvertebrates in two localities (Isla Palma and Los Negritos) of Malaga Bay was studied. This bay is located in the Pacific coast of Colombia and was recently declared National Natural Park. The rapid ecological assessment revealed a total of 128 species belonging to 64 families and 11 classes (including threatened species). The most common groups were: Gastropoda (27%), Polychaeta (26%), Malacostraca (16%) and Pelecypoda (13%). Even though the two sites are relatively near, being apart only by 6 km, the composition of the respective communities was very different. They shared only 7.8% of the species found; which might have profound and interesting effects for conservation purposes.

Fifteen species of echinoderms (5 asteroids, 5 echinoids and 5 ophiuroids) are reported for Natural National Park Ensenada deUtria in the Pacific coast of Chocó, Colombia. For each species, we report its size and ecological observations. Two species, Mithrodia bradleyi and Encope ecuadorensis are new records for the Colombian Pacific coast and are described shortly., Most of the echinoderms found were associated to rocky shores, coral reef and sometimes sandy shores, except Ophiothríx spicuiata and Ophiactis savignyi, which were found living in association with the gorgonia Lophogorgia alba. Hesperocidaris asteriscus and Centrostephanus coronatus live in holes in coral or rock. These are mainly intertidal or shallow subtidal species.

The hermaphrodite condition of the cockles Anadara tuberculosa and Anadara similis, gonochoric species living in mangroves of the Pacific coast of Colombia, are described in this paper. The gonads of 290 individuals of A. tuberculosa and 336 individuals of A. similis collected in five localities of the Colombian Pacific coast were analyzed using histological methods. Our results exposed that 3.1 % of A. tuberculosa and 3.0 % of A. similis analyzed showed signs of both ovules and spermatozoids, as well as simultaneous sexual maturation. Based on this frequency of occurrence of hermaphrodite individuals and the fact that hermaphrodite organisms were present in most of the sampling sites, we conclude that hermaphroditism is a normal rather than casual condition of these two species. We suggest that future studies in the hermaphroditism of these organisms center on the determination of factors potentially affecting this condition.

<p>Although the Eastern Tropical Pacific is well known for its diverse fauna, the seabirds occurring off Costa Rica’s Pacific coast have received little scientific attention. With seabirds now the fastest declining avian group, a better understanding of seabird diversity and abundance in this region is urgently needed. We report on observations of Costa Rica’s Pacific seabirds made during 19 days of observations on 11 offshore trips from 2006-2010. We provide, for the first time, spatially and seasonally explicit information on the distribution of 41 species of seabirds (nine families). Species diversity is higher during the dry-wet season (36 species) and wet-dry season transitions (36 species) than during the dry season (19 species). The fauna included three threatened species (<em>Pterodroma phaeopygia</em>, <em>Procellaria parkinsoni</em>, and <em>Puffinus creatopus</em>) and two near-threatened species (<em>Psueudobulweria rostrata</em> and <em>Thalasseus elegans</em>), highlighting the importance of Costa Rican waters for the conservation of seabirds.</p><div> </div>

The Pacific Coast of Colombia has a complex history of change and upheaval. How is one to reach to it, with the variety of its human experiences? And how to grasp it from the diverse and often fragmentary sources that are its archaeology?

Lingulids and discinids are the only brachiopods that exhibit life histories that include a feeding planktonic stage usually referred to as a “larva”. We collected planktotrophic brachiopod larvae from the Pacific and Caribbean coasts of Panama and took a DNA barcoding approach with mitochondrial cytochrome c oxidase subunit I (COI), mitochondrial ribosomal 16S, and nuclear ribosomal 18S genes to identify those larvae and to estimate their diversity in the region. We observed specimens from both coasts with distinct morphologies typical of lingulid and discinid larvae. COI and 16S were sequenced successfully for the lingulid larvae but failed consistently for all discinid larvae. 18S was sequenced successfully for larvae from both families. Sequence data from each gene revealed one lingulid operational taxonomic unit (OTU) from Bocas del Toro on the Caribbean coast, and one lingulid OTU from the Bay of Panama on the Pacific coast. These OTUs differed by >20% for COI, >10% for 16S and ~0.5% for 18S. Both OTUs clustered with GenBank sequences of Glottidia species, the only genus of lingulids in the Americas, but were distinct from G. pyramidata the only species reported for the Caribbean. Analysis of 18S sequence data for discinid larvae recovered 2 OTUs, one exclusively from the Pacific and one with a mixture of Pacific and Caribbean larvae. The 18S marker does not provide enough resolution to distinguish between species, and comparisons with GenBank sequences suggest that one OTU includes Pelagodiscus species, while the other may include Discradisca species. When compared with other marine invertebrates, our surveys of brachiopod larvae through DNA barcoding show relatively low levels of diversity for Panama.
