Composición, riqueza y abundancia de coleópteros (Coleoptera) asociados a bosques semideciduos y vegetaciones ruderales en la Sierra del Rosario, Cuba

En tres bosques semideciduos y en tres tipos de vegetación ruderal del Área Protegida de Recursos Manejados Mil Cumbres (Sierra del Rosario, Pinar del Río, Cuba), se analizan las comunidades de coleópteros y se las compara respecto a la composición, riqueza, abundancia, diversidad, equitatividad, ordenación y complementariedad. La composición de coleópteros conocida hasta el momento es de 166 especies, incluidas en 75 géneros y 34 familias. La vegetación ruderal presentaó mayor riqueza y abundancia que los bosques semideciduos. El bosque y la vegetación ruderal de Pan de Guajaibón exhibieron los valores más altos de riqueza, abundancia y número de especies únicas. Ambas formaciones vegetales de Sierra Chiquita presentaron la mayor diversidad y equitatividad. Las comunidades de coleópteros más afines estaban entre los bosques y entre la vegetaciones ruderales en Forneguera y Pan de Guajaibón. Cada bosque y tipo de vegetación ruderal presentaba especies exclusivas.

Biología reproductiva de Polioptila lembeyei (Aves: Polioptilidae) en la Reserva Ecológica Siboney-Juticí, Santiago de Cuba, Cuba

Se estudió la biología reproductiva de Polioptila lembeyei en la Reserva Ecológica Siboney-Juticí, Santiago de Cuba, Cuba durante los años 2006 y 2007 en seis formaciones vegetales. Se describieron aspectos de su reproducción en términos de cronología reproductiva, tamaño de puesta, duración del período de incubación, permanencia de los polluelos en el nido, morfometría de nidos y huevos, y caracterización del sitio de nidificación en cuanto a la altura de los nidos y especie y altura de las plantas utilizadas como sitio de nidificación. Se localizaron 89 nidos durante las dos temporadas reproductivas, 43 en el año 2006 y 46 en el 2007. El período reproductivo se extendió desde finales de marzo hasta julio, abarcando 129 días en el año 2006 y 122 días durante el año 2007. Las nidadas tuvieron una duración de 36–56 días (construcción 8,6 ± 2,8 días, puesta 8,6 ± 2,7 días, incubación de 14,0 ± 1,2 días y permanencia de los pichones en el nido 14,5 ± 1,0 días). De los 45 nidos examinados el tamaño de puesta modal fue de tres huevos (88,9 %), encontrándose también nidadas de dos (6,7 %) y cuatro huevos (4,4 %). De 38 nidos con huevos para ambas temporadas, 15 nidos produjeron pichones (32 pichones en el 2006 y 20 pichones en el 2007) y solo tres nidos durante el 2006 (37,5 %) lograron producir volantones, los cuales salieron con éxito del nido. La planta más utilizada como sitio de nidificación fue Acacia macracantha (80 % de los nidos detectados), aunque también se hallaron nidos en otras ocho especies de plantas. Las alturas de ubicación del nido fue de 2,7 ± 1,5 m (n = 82; rango 0,3–6,4 m) y la distancia del nido al dosel de la planta utilizada como sustrato fue de 1,1 ± 0,9 m (n = 80; rango 0,1–5,4 m).

Sensaciones térmicas en la provincia Cienfuegos (Cuba)

Los estudios referentes a las sensaciones térmicas son de gran interés y utilidad en diferentes sectores de la sociedad, máxime en la provincia Cienfuegos (Cuba) donde existe un alto potencial económico en continuo desarrollo. Es por eso que este trabajo tiene como objetivo caracterizar temporal y espacialmente las sensaciones térmicas en horarios extremos del día en la provincia Cienfuegos durante el período 1981-2010. Para ello se calcularon los índices bioclimáticos Temperatura Efectiva-TE y Temperatura Efectiva Equivalente-TEE los cuales resultan adecuados para evaluar las sensaciones térmicas de los cubanos aclimatados a las condiciones cálidas y húmedas. Como principales resultados se obtuvo que en la provincia, las mañanas de noviembre a abril son generalmente frescas mientras las tardes de ese período pueden ser confortables o calurosas. Esta última situación es común en las mañanas de mayo a octubre cambiando a calurosas o muy calurosas en horas de la tarde. Las mayores diferencias espaciales se encontraron entre el litoral sur oriental y la zona montañosa resaltando esta última por una permanencia de sensaciones frescas o confortables.

Amphibian Hotspots and Conservation Priorities in Eastern Cuba Identified by Species Distribution Modeling

The high rate of amphibian endemism and the severe habitat modification in the Caribbean islands make them an ideal place to test if the current protected areas network might protect this group. In this study, we model distribution and map species richness of the 40 amphibian species from eastern Cuba with the objectives of identify hotspots, detect gaps in species representation in protected areas, and select additional areas to fill these gaps. We used two modeling methods, Maxent and Habitat Suitability Models, to reach a consensus distribution map for each species, then calculate species richness by combining specific models and finally performed gap analyses for species and hotspots. Our results showed that the models were robust enough to predict species distributions and that most of the amphibian hotspots were represented in reserves, but 50 percent of the species were incompletely covered and Eleutherodactylus rivularis was totally uncovered by the protected areas. We identified 1441 additional km2 (9.9% of the study area) that could be added to the current protected areas, allowing the representation of every species and all hotspots. Our results are relevant for the conservation planning in other Caribbean islands, since studies like this could contribute to fill the gaps in the existing protected areas and to design a future network. Both cases would benefit from modeling amphibian species distribution using available data, even if they are incomplete, rather than relying only in the protection of known or suspected hotspots.

Anglicisms and calques in upper social class in pre-revolutionary Cuba (1930–1959): A sociolinguistic analysis

The geographical proximity and socioeconomic dependence on the United States brought about a deep rooted anglicization of the Cuban Spanish lexis and social strata, especially throughout the Neocolonial period (1902–1959). This study is based on the revision of a renowned newspaper of that time, Diario de la Marina, and the corresponding elaboration of a corpus of English-induced loanwords. Diario de la Marina particularly targeted upper social class, and only crónicas sociales (society pages’ columns) and print advertising were revised because of their fully descriptive texts, which encoded the ruling class ideology and consumerism. The findings show that there existed a high number of lexical and cultural anglicisms in the sociolect in question, and that the sociolinguistic anglicization was openly embraced by the upper socioeconomic stratum, entailing a differentiating sign of sophistication and social stratification. Likewise, a number of the anglicisms collected, particularly those related with social events, are unused in contemporary Cuban Spanish, which suggests a major semantic shifting in this sociolect after 1959.

Letters from Benjamin Welles to John Henry Tudor, 1799-1801

Benjamin Welles wrote these six letters to his friend and classmate, John Henry Tudor, between 1799 and 1801. Four of the letters are dated, and the dates of the other two can be deduced from their contents. Welles wrote Tudor four times in September 1799, at the onset of their senior year at Harvard, in an attempt to clear up hurt feelings and false rumors that he believed had caused a chill in their friendship. The cause of the rift is never fully explained, though Welles alludes to "a viper" and "villainous hypocrite" who apparently spread rumors and fueled discord between the two friends. In one letter, Welles asserts that "College is a rascal's Elysium - or the feeling man's hell." In another he writes: "College, Tudor, is a furnace to the phlegmatic, & a Greenland to thee feeling man; it has an atmosphere which breathes contagion to the soul [...] Villains fatten here. College is the embryo of hell." Whatever their discord, the wounds were apparently eventually healed; in a letter written June 26, 1800, Welles writes to ask Tudor about his impending speech at Commencement exercises. In an October 29, 1801 letter, Welles writes to Tudor in Philadelphia (where he appears to have traveled in attempts to recover his failing health) and expresses strong wishes for his friend's recovery and return to Boston. This letter also contains news of their classmate Washington Allston's meeting with painters Henry Fuseli and Benjamin West.
