Although the Polycladida (Platyhelminthes) are prominent members of many reef communities, no comprehensive surveys exist for the Caribbean coast of Colombia. This study represents a first survey of the Colombian polyclad fauna. A total of 25 species were collected from the rocky littoral of the Tayrona National Park, Santa Marta, Colombia. Because color and color patterns represent major taxonomic characters in the classification of polyclads, photographic records were obtained from live specimens prior to fixation. Further taxonomic identification was based on major external features and serial longitudinal sections of the reproductive system. Numerically, Boninia divae Marcus and Marcus, 1968, followed by Styloplanocera fasciata (Schmarda, 1859) were the most abundant species. Not only do all recorded species constitute first records for the Colombian coast of the Caribbean, but Cestoplana rubrocincta (Grube, 1840), Armatoplana divae (Marcus, 1947), Phaenoplana longipenis (Hyman, 1953), Eurylepta aurantiaca Heath and McGregor, 1912, Thysanozoon cf. lagidum Marcus, 1949, and Prosthiostomum gilvum Marcus, 1950 represent first records for the entire Caribbean region. Furthermore, a new combination Phrikoceros mopsus nov. comb. is proposed, and a possible new species of Pleioplana Faubel, 1983 was found.Aunque los Polycladida (Platyhelminthes) son miembros prominentes de muchas comunidades arrecifales, no existe ning n estudio para la costa del Caribe Colombiano, convirti ndose este en el primero para la fauna de polycladidos de Colombia.

Sipunculans represent a discrete component of the coral reef ecosystem, since they live inside the calcareous structure. They are an important component in terms of biomass and number of organisms. The present study describes the diversity of sipunculans living inside massive coral skeletons. A total of 43 blocks of dead coral skeletons from Montastraea cavernosa, Montastraea annularis and Diploria strigosa were collected from nearby coral reef areas off Santa Marta, on the Colombian Caribbean coast. Using hammer and chisel, blocks of approximately 1 dm3 were broken into small pieces, from which the sipunculans were extracted. A total of 381 organisms were obtained from the coral blocks comprising four families and 10 species. All the species found have been widely reported in different studies from the Caribbean region. Aspidosiphon fischeri and Phascolosoma perlucens were the two most abundant species comprising more than 60% of the total organisms with a mean density of 18.52 ± 4.64 organisms dm−3. Dead coral substrate from M. cavernosa had the greatest abundance (N = 148), followed by D. strigosa (N = 121) and M. annularis (N = 112). There were no significant differences in the abundance, richness, and diversity of sipunculans between coral skeletons; and within samples there was high variability suggesting that the skeletal substrates analysed came from coral skeletons of different unknown ages of succession. These results describe the sipunculan community structure that live inside three important massive coral skeletons, and contributes to the knowledge of the cryptobiota diversity of the Santa Marta area of Colombia.

Two new species of Brazilian Psychoda Latreille are described, and Psychoda alternata Say and P. zetoscota Quate are recorded for the first time from Brazil. Psychoda divaricata Duckhouse, already described from southern Brazil, was recorded in the northeastern part of that country, as well as in the eastern Amazon region. The supraspecific classification proposed for the species of Psychoda according to Quate (= Psychodini of Jeñek) are discussed. A new classification is suggested that considers only one genus, Psychoda, divided into 12 subgenera: subgenus Psychoda Latreille, subgenus Copropsychoda Vaillant, subgenus Falsologima Jeñek & Harten, subgenus Psychodula Jeñek, subgenus Psychomora Jeñek, subgenus Psychana Jeñek & Harten, subgenus Logima Eaton, subgenus Tinearia Schellenberg, subgenus Chodopsycha Jeñek, subgenus Ypsydocha Jeñek, subgenus Psychodocha Jeñek, and subgenus Psycha Jeñek. A list of the Psychoda species from Latin America and the Caribbean region is presented.

AbstractThe dense Miocene record of cetaceans is known from localities along the coasts of all continents, mostly in the northern Atlantic or the eastern Pacific regions, but Antarctica. Fossils from the Caribbean region are few and include of a couple of findings from Panama and Venezuela. Here, we report a partly complete skull from the Caujarao Formation (middle Miocene), Falcon State, Caribbean region of Venezuela. Our phylogenetic analyses indicate that the Caujarao specimen is a ‘stem delphinidan’, a group that includes several taxa of early diverging odontocetes whose phylogenetic affinities remain a matter of debate. The fossil record has shown that this group of stem delphinidans was taxonomically diverse, but displayed a somewhat homogeneous cranial patterning, with most of the variations being found within the mandible or tympanoperiotic characters. As other stem delphinidans the Caujarao odontocete displays an enlarged temporal fossa and a fairly symmetrical cranium. Because the skull is missing several key diagnostic characters due to the preservation state of the specimen, a more precise taxonomic identification is not possible. Despite this, the finding of this specimen highlights the importance of the fossil record from the Neogene of Venezuela, and the importance of the area to understand cetacean evolution in the proto-Caribbean.

Forty nine macroalgal species (7 Chlorophyta, 4 Phaeophyta and 38 Rhodophyta) are reported for the first time for the Banco de las Animas, at the southwest of Santa Marta City (Salamanca Gulf, Colombia). The collections were made between 20 and 30 m depth. The green alga Halimeda gracilis Harvey ex J. Agardh and the red ones Corynomorpha clavata (Harvey) J. Agardh, Cryptonemia sp., Acrothamnion butleriae (Collins) Kylin, Antithamnion ogdeniae Abbott, Antithamnionella breviramosa (Dawson) Wollaston in Womersley and Bailey, Hypoglossum simulans Wynne, Price et Ballantine and H. subsimplex Wynne, are new records for the Caribbean coast of Colombia.

Herein, a new habitat for the heterobranch mollusk Umbraculum is described. One specimen was found on a Thalassia testudinum bed at Taganga Bay at 3 m depth, a buffer area of the Tayrona National Park, Colombian Caribbean. To the best of our knowledge, these mollusks have not been previously reported in this kind of habitat. Seagrasses may provide protection and possibly serve as areas for its reproduction.

We report Coelosis biloba for the rainforest of the buffer zone of Paramillo Natural National Park, south of Córdoba. The specimen was collected at night, in a mist net to catch bats. This represents a new location for the distribution of this species in Córdoba and the sixth record for the northern coast of Colombia. The few records of this species in northern Colombia compared to other regions of the country are due to lack of studies in biodiversity and the absence of entomological collections at universities on the Caribbean coast.

This study aimed to assess abundance and habitat use by juvenile and adult damselfishes, as much as the benthic cover of different reefs on Isla Colon, Bocas del Toro, Panama. Reefs were selected considering different levels of wave exposure and depths. Damselfish and benthic communities were distinct between reefs. The most abundant species in the sheltered deeper reef was Stegastes planifrons followed by S. leucostictus, and they were also recorded in the sheltered shallower reef. Low densities of S. partitus and S. variabilis were also observed in the sheltered deeper reef, as these species are apparently restricted to higher depths. Additionally, these reefs presented patches with high cover of live and dead massive coral. Shallow depths presented high abundances of S. adustus, indicating a preference of this species for shallow habitats and exhibiting a two-fold increase in abundance at higher wave surge. Also, Microspathodon chrysurus reached higher numbers in shallow depths. Furthermore, the exposed reef presented a high cover (%) of algae groups and the fire-coral Millepora alcicornis, acknowledged as a preferred habitat for M. chrysurus and other reef fish. In this study, distinct habitat uses were observed, with patterns regulated by depth and/or wave exposure levels and/or availability of specific benthic cover. For site-attached species as damselfish, habitat specialization, competition and/or non-random recruitment patterns have been found to rule distributional patterns. Similar results for damselfish relative abundances were found compared to studies conducted within Panama and other reefs throughout the Caribbean region over three decades ago, indicating strong habitat affinity for the most abundant species. However, severe reductions of habitat availability following coral mass-mortality events may have disrupted their distributional patterns.

Eighteenth And Nineteenth Centuries

Scotland is gradually coming to terms with its involvement in slavery and colonialism as part of the British Empire. This article places the spotlight on the lives of African Caribbean people who were residents of Edinburgh during the eighteenth and nineteenth centuries. I discuss their varied experiences and contributions: from runaways and men fighting for their freedom in the Scottish courts to women working as servants in city households or marrying into Edinburgh high society. The nineteenth century saw activism among political radicals from abolitionists to anticolonialists; some of these figures studied and taught at Edinburgh University. Their stories reflect the Scottish capital’s many direct connections with the Caribbean region.
