Typhlops leptolepis sp. nov. is a new blind snake from Holguín Province, northeastern region of Cuba. The new species is characterized by its small and thin body size, as well as a narrow rostral in dorsal view, longer than broad, with parallel to curved sides, tapering toward anterior tip. The preocular is in contact with third supralabial only. It has 20 anterior scale rows reducing to 18 posteriorly at around midbody or posterior to midbody, moderate to high middorsal scale counts (250- 308), and a peculiar coloration (head, neck, and tail whitish spotted in ventral view). Based on its morphology, the new species can be placed within the Typhlops lumbricalis species group and a key to the species belonging to this group is presented. Copyright © 2013 Magnolia Press.

An assessment of the population dynamics of Microtityus jaumei Armas (Scorpiones: Buthidae) on the slopes south of Sierra de Canasta, Guantnamo Province, Cuba show an increase in activity over the year (≤ 0.05). The activity peak is related to the reproductive period from June to November. The abundance of scorpions was significantly related to density of the canopy and thickness of the substrate.

The floristic richness, endemism and life forms of eight types of vegetation of the coastal terraces of the Baconao Biosphere Reserve were analyzed. Starting from recollections in field expeditions, the revision of herbarium materials and floristic inventories precedent, the list of vegetable species was elaborated. 757 species belong to 387 genus and 87 botanic families were identified. From all floristic list, 108 were introduced plants an 649 natives, 164 endemics. Shrubwoods and semideciduous forests present the biggest richness of species and endemism; besides high biological similarity, due to the edaphic conditions on that they are developed. The families with more specific richness were Leguminosae (96), Malvaceae (58), Rubiaceae (42), Euphorbiaceae (41), Apocynaceae (34), Boraginaceae (33) and Poaceae (29). The Amazonian-centered floristic elements were predominant (59.2 %), followed by laurasian elements (22.4 %) and unknowed center (18.4 %), with prevalence of Amazonian-centered shrubs. 164 endemic species were classified, of which 58 are pancubans, 45 sectorials, 26 districts and 35 multisectorials. The presence of eight endemic genera was significative, seven monospecific. 35 species were registered as threatened, 22 of them are endemics plants located at protected areas with strict category of handling. Nine life forms were founded, mostly shrubs (282), trees (179), herbs (138) and climbing plants (108). © 2015, Universidad Nacional de Colombia. All rights reserved.

A checklist of the semiaquatic and aquatic Heteroptera from Cuba is presented, based on literature records and examination of entomological collections. A total of 74 species and 1 morphospecies, 35 genera, and 16 families of the infraorders Dipsocoromorpha, Leptopodomorpha, Gerromorpha, and Nepomorpha are listed. Seven of the represented species are endemic to Cuba (9.5%), 7 of the Caribbean subregion (9.5%), and 13 of the Neotropics (17.6%). The most diverse families in the country are Gerridae (14 species), Veliidae (12 species), and Corixidae (11 species). Available distributional and habitat data are provided for each species.

The Dominican Republic moss flora stands out within the Caribbean countries because of the high species richness and number of disjuncts. The flora is comprised of 467 taxa in 207 genera, and 61 families. We report 62 new records and 82 disjuncts for this flora that shows affinity with other Greater Antilles and Central America. Within the context of the Caribbean and in terms of conservation, this flora is important because it represents both the highest reported moss species richness and 82 unique disjuncts within the West Indies. © 2010 President and Fellows of Harvard College.

The semideciduous forests of the extreme east Cuba were studied in Sabana and Maisí areas, Guantanamo province, over karstic formations, whose rainfalls fluctuate between 600 to 1000 mm each year, with a marked dry period. By using the Zurich-Montpellier school methodology, two associations new for science are described. Calophyllo antillani- Ocoteetum coriaceae in ferralitic red and fertile soils (mesophil semideciduous forest) and Thouinio patentinervis-Burseretum simarubae (microphil semideciduous forest) on "lapiez", with a defined root mats where this ecosystem's nutrient cycle is produced.

From 2005-2008 we used counts of visible migrants at an inland watchsite (La Gran Piedra) 9 km from the coast and a coastal watchsite (Siboney) to describe the magnitude and timing of Osprey (Pandion haliaetus) autumn migration through southeastern Cuba from 1 August through 30 November. Counts of Ospreys at Siboney averaged 5283 (2006-2008) annually or roughly twice those tallied at other North American watchsites known for the concentration of this species during autumn migration. Nevertheless, simultaneous counts at both watchsites better represent the magnitude of its migration through southeastern Cuba, averaging more than 7000 Ospreys (3 yr). The mean seasonal passage window (95% of the flight) ranged from 78 to 83 d at La Gran Piedra and Siboney. The average peak at both sites occurred in early October, with more than 20 Ospreys/hr. The daily passage window (95% of the daily passage) was more protracted at Siboney, where birds migrated both early in the morning and late in the afternoon, than at the inland mountain site at La Gran Piedra, where Osprey numbers peaked at midday. We believe that Ospreys migrating in southeastern Cuba move from the coast to the mountains at midday in response to thermal convections along the mountains at that time. Osprey flocks observed at watchsites ranged between 2-52 individuals and one flock of 92 individuals was observed at a dam in central Cuba. © 2014 The Raptor Research Foundation, Inc.

We describe a new species of the genus Otiothops MacLeay, 1839 (Palpimanidae), O. alayoni n. sp., from the Sierra Maestra mountain range in eastern Cuba, representing only the second species of the genus from the Greater Antilles. The new species is diagnosed from other species of the genus, and compared in detail with the Cuban O. walckenaeri Macleay, 1839. All specimens of the new species were collected by sifting leaf litter in montane rainforest. © 2014 British Arachnological Society. All Rights reserved.

The Mogotes (karstic dome hill) of Gran Meseta de Guantánamo karst are over Charco Redondo formation. Air temperature vary from 22 to 24°C and rainfall from 1 200 to 1 400 mm annually. By using the Zurich - Montpellier school methodology we describe a new order, Coccothrinaci leonis - Guapiretalia rufescentis, with the alliance Coccothrinaci leonis - Guapirion rufescentis and three associations. Bactrio cubensis - Podocarpodetum ekmanii and Phyllantho epiphyllanthi - Tabebuietum myrtifoliae occupy the top of mogotes with a well-developed rot mat where this ecosystem's nutrient cycle is concentrated. Pileo fruticulosae - Thelypteridetum alatae grow in vertical fragments.

The area occupied by Pinus cubensis in the northeastern region of Cuba is studied according to the Zurich Montpellier methodology. This area with ofiolits bedrock and ferritic soils are phytosociologically very diverse, supporting three alliances, five suballiances and 22 associations. Of them two alliances, five suballiances and six associations are firstly described in this paper, but other combinations, as well. Bactri cubensis-Pinion cubensis characterizes the wet pines forests. It groups Panico-Pinenion cubensis with one association distributed toward the western area and Cyrillo nipensis-Pinenion cubensis with eigh associations in the eastern part. Guettardo ferrugineae-Pinion cubensis occurs in mesic and dry habitats. It is composed by Caseario crassinervis-Pinenion cubensis with three associations in the west region, Garcinio-Pinenion cubensis with six associations in the very extreme habitats and Dracaeno cubensis-Pinenion cubensis with three associations distributed in dry habitats. Agavo albescentis-Pinion cubensis with one association in lower areas occurs on calcareous sandstone.
