ABSTRACT The in vitro and vivo antileishmanial cytotoxic activities of thymol structural derivatives comparison to those Glucantime were studied. results showed here suggest that hemisynthetic have promising potential could be considered as new lead structures the search for novel drugs.
We studied various aspects of the reproductive biology Magdalena River turtle (Podocnemis lewyana) during 2 nesting seasons in locations Mompos Depression northern Colombia. monitored 53 nests; 22 that completed incubation situ, 24 were transferred to protected areas (transferred nests), and 7 constructed using eggs removed from females had been consumed by local people ("oviductal" nests). For each nest, we registered oviposition date, distance nearest body water, soil type, vegetative...
We obtained evidence of the continued presence Podocnemis lewyana in 18 different sites within Magdalena River drainage northern Colombia. However, abundances at most were low, even areas where species had previously been reported as common. Although hunting adults is no longer commercially viable, local people consume individuals that are captured incidentally while fishing. Hunting eggs during incubation period each year continues to be intensive. Turtle negatively related human densities...
We implemented a species distribution modelling approach to establish the potential of Podocnemis lewyana , explore climatic factors that may influence species’ and evaluate possible changes in under future climate scenarios. The models predicted continuous from south north along Magdalena River, Rivera Palermo department Huila departments Atlantico north. Temperature was variable most influential P. ; this tends be present warm regions with low temperature variability. model an increase...
We describe a new species of Dendrobatidae from the eastern flank northern Central Cordillera in Colombia and assign it to recently named genus Leucostethus. also assess phylogenetic status Colostethus fraterdanieli "complex" which according our inference, is closely related species. use morphological, genetic bioacoustic evidence expand phylogeny As result, we transfer content C. The differs Leucostethus by having white testes, straight pale ventrolateral stripes high divergence (17%...
The northern Andes are a geographically, climatically, and ecologically complex area that harbors high number of species presents level of endemism. However, the landscape this region has been highly transformed by human activities, including agriculture, cattle grazing, urbanization, recently, construction large infrastructure projects. This study list amphibians reptiles compiled from field surveys carried out between 2006 2016 in protected areas surrounding 2...
Nest-site selection by female Trachemys callirostris was studied on an island in the Pijiño wetland of Mompos Depression Colombia. We quantified distances nests to shoreline and compared vegetative cover soil types at nest locations randomly selected points island. Nests sites were concentrated first 5 m from always located under cover. Such might reduce thermal stress nesting females, lower probability detection predators, buffer incubating eggs environmental extremes. Females...
The glassfrog genus Cochranella, with nine recognized species, is distributed in the lowlands and mid elevation of Neotropical forests, from Nicaragua to Bolivia (Guayasamin et al. 2009; Twomey 2014). Four species are trans-Andean—C. granulosa (Taylor 1949) occurs mountains, at elevation, Central America, C. litoralis (Ruiz-Carranza & Lynch 1996) mache Guayasamin Bonaccorso 2004 occur Pacific western cloud forests Colombia Ecuador, euknemos (Savage Starrett 1967) both America South...
To assess the conservation status of endemic species we examined population trends in three frog with different life histories. We performed a mark-recapture field experiment protected area on eastern flank Cordillera Central northern Andes Colombia. marked and followed 123 individuals Pristimantis jaguensis, 178 Colostethus aff. fraterdanieli, 83 Dendrobates truncatus. The survival probability growth rate P. jaguensis varied as function capture occasion, while recapture was constant. In two...
IUCN Red Lists have been a valuable tool to prioritize conservation plans in endemic neotropical frogs. However, many areas this region are poorly known terms of their diversity and endemism. Based on examined museum specimens the threatened species Pristimantis penelopus we revised its geographic distribution determined habitat suitability using niche modeling techniques. Using mitochondrial fragment COI gene, determine phylogenetic position extent genetic variation across Colombia. We...
Ante la necesidad de desarrollar nuevos medicamentos para el tratamiento leishmaniasis cutánea que sean efectivos, seguros, mayor aceptación entre los pacientes, fáciles administrar en entornos rurales y más económicos, presente estudio se evaluó in vitro e vivo potencial terapéutico perfil citotoxicidad un extracto etanólico glicólico las ramas Caesalpinia spinosa (Molina) Kuntze sus respectivas formulaciones: loción emulsión. Asimismo, validó utilidad dos formulaciones como tópico diez...
Current research looks at the scientific findings on potential of Cannabis to treat skin lesions, discovering role played by endocannabinoid system in maintaining healthy and wound healing, validating topical treatment cutaneous lesions. Due its anti-inflammatory healing properties, study aimed confirm vitro vivo antileishmanial effect spp. Three ethanol extracts from Nicole Kush strain (75% C. indica 25% sativa) were prepared percolation. The cytotoxicity was evaluated different cell lines...
Two populations of the endangered Magdalena River turtle, Podocnemis lewyana, separated by 55 km in Mom-pos Depression were sampled to quantify levels genetic variation and inspect for evidence structure. Allozyme analyses resolved 22 presumptive gene loci, but only one resulted polymorphic. Genotype proportions at this locus departed from those expected under Hardy-Weinberg equilibrium, showing heterozygote deficiencies both populations. However, allele frequencies did not differ between...
