| Ecuador harbors one of the most diverse Neotropical scorpion faunas, hereby updated to 47 species contained within eight genera and five families, which inhabits the “Costa” (n= 17), “Sierra” (n= 34), “Oriente” (n= 16) and “Insular” (n= 2) biogeographical regions, corresponding to the western coastal, Andean, Amazonian, and the Galápagos archipelago regions, respectively. The genusTityus Koch, in the family Buthidae, responsible for severe/fatal accidents elsewhere in northern South America and the Amazonia, is represented in Ecuador by 16 species, including T. asthenes, which has caused fatalities in Colombia and Panama, and now in the Ecuadorian provinces of Morona Santiago and Sucumbíos. Underestimation of the medical significance of scorpion envenoming... |

| We describe a new species of Enyalioides from lowland cloud forests in southwestern Ecuador. This represents the third species in the genus known to occur west of the Andes in South America; the other two species are E. heterolepis and E. oshaughnessyi. Among other characters, the new species can be distinguished from other members in the genus by having small, keeled, paravertebrals; a series of skin folds on the lateral aspects of body and neck; size-homogeneous scales on body and limbs; distinct caudal segments; and an extensive dark patch on the gular region of adult males. Morphological similarity suggests that the new species, which we call E. touzeti, is closely related to E. oshaughnessyi. |

| The relationship between human papillomavirus (HPV) and oropharyngeal squamous cell carcinoma has been established. However, data from Ecuador is limited. The objective of this study was to characterize HPV infection in Ecuadorian patients with tongue cancer. Fifty-three patients with tongue cancer treated at the tertiary referral center Sociedad de Lucha Contra el Cancer (SOLCA), Guayaquil, between 2006 and 2011 were identified. Linear Array® HPV genotyping was used to identify the presence and types of HPV on formalin-fixed paraffin-embedded biopsy samples from these patients with tongue cancer. HPV was identified in 42% (n=22) and high-risk (HR) HPV in 17% (n=9), with 18 different HPV types identified. The most common types were the HR HPV 33 (14%) and... |

| Insect-food-plant associations have been shown to be influenced by the chemical, physical and nutritional characteristics of plants. We suggest that among insect larvae that use leaf material to build shelters, food-plant use may be constrained by differences in host leaf structure, illuminating a rarely investigated aspect of insect-plant interactions. To explore the potential effects of leaf structure on shelter building behavior in a Neotropical skipper butterfly, we investigated shelter building patterns on two congeneric food-plants that varied in leaf thickness. Shelter architecture varied significantly between hosts, with thicker leaves requiring longer cuts to construct shelters. The relationship between shelter building behavior and leaf structure... |

| Potato farmers in Ecuador rely on chemical inputs to manage pests and optimize yields. Integrated pest management techniques lower production costs, reduce pesticide exposure, and improve long-term agricultural sustainability. Public extension does not, however, exist in Ecuador and cost-effective means of communicating complex messages to producers are needed. We analyze cost-effectiveness of alternative dissemination methods, including farmer field schools (FFS), field days, pamphlets, and word-of-mouth transmission. Field days and pamphlets have strong impacts on adoption, especially considering their low costs. FFS are effective, but expensive. Evidence also indicates significant diffusion from FFS to non-FFS farmers, indicating high... |

| Critics suggest that Reducing Emissions from Deforestation and forest Degradation (REDD+) may not generate improvements in well-being for participating stakeholders, and may in fact undermine indigenous rights. To ensure positive social benefits from REDD+ projects, the United Nations REDD Programme has proposed core safeguards, including local stakeholder participation; free, prior, and informed consent; and equitable distribution of benefits. However, there is little experience to date in implementing and evaluating these safeguards. We apply these core safeguards as a framework to study how people in indigenous communities in the Ecuadorian Amazon perceive and benefit from Programa Socio Bosque, a conservation incentive program in Ecuador’s... |

| Fueron estudiadas, para la búsqueda de rotavirus, 341 muestras fecales obtenidas de sendos niños menores de cinco años con diarrea aguda, atendidos en dos centros de salud de la ciudad de Loja - Ecuador. De ellas, 56 (16%) fueron positivas para rotavirus, siendo genotipificadas 33 muestras para la determinación de genotipos G y P. Los genotipos más frecuentes fueron G4 (42%), P[6] (36%) y la combinación mixta G4+9P[6] (21%). Este es el primer estudio de carácter molecular en rotavirus realizado en el sur de Ecuador y los datos obtenidos ratifican la variabilidad de cepas de rotavirus circulantes en este país. |

| El nuevo grupo Drosophila asiri pertenece al subgénero Drosophila. Los ejemplares fueron capturados en los bosques andinos del Ecuador, desde los 3200 hasta los 4000 m de altitud. A este grupo pertenecen Drosophila (D.) asiri Vela & Rafael, 2005 previamente ubicada dentro del grupo D. onychophora, y dos nuevas especies; Drosophila (D.) yuragyacum sp. nov. y Drosophila (D.) yanaurcus sp. nov. Las capturas se realizaron en el bosque protector Pasochoa, en la quebrada de Cruz Loma y en el páramo de Papallacta, utilizando cebo de banano y levadura. Los miembros del nuevo grupo por el momento son endémicos de los Andes ecuatorianos. Las tres especies del grupo D. asiri son moscas de tamaño grande (aproximadamente 6 mm). Los machos presentan el edeago... |

| Women living in Latin American countries bear a disproportionate burden of cervical cancer, a condition caused by infection with the human papillomavirus (HPV). We performed a study in Santa Elena, Guayas (currently Santa Elena Province), Ecuador, to determine how often HPV could be detected in women attending a private cancer screening clinic. Participants underwent a Pap test, and vaginal and cervical swabs were performed for HPV testing by the polymerase chain reaction (PCR). Each participant completed a verbally administered survey. The mean age of 302 participants was 37.7 years (range 18 to 78 years). The majority of cervical and vaginal specimens contained sufficient DNA to perform PCR. Overall, 24.2% of the participants had either a cervical or... |

| This study conducts a gender analysis of homeownership in Ecuador, drawing upon data collected through the nationally-representative 2010 Ecuador Household Asset Survey carried out by the authors. The survey collected data on asset ownership both at the household and individual levels. This allows us to overcome a typical problem faced by gender analyses, that of only having the sex of the household head and not the sex of the owner(s). The study explores gender differences in homeownership and housing wealth. There is fairly equal distribution of homeownership and housing wealth, which is not all that surprising given the partial community property marital regime. Any property purchased during marriage or while in a consensual union is considered... |

| El Cóndor Andino (Vultur gryphus) se encuentra en declinación, mientras que en Ecuador la mayoría de los esfuerzos de monitoreo se han concentrado en el norte del país. En este trabajo se generó un modelo de distribución potencial del Cóndor Andino para los Andes sur de Ecuador. La altitud y la estacionalidad climática fueron variables importantes en el modelo. Las localidades de mayor altitud son los sitios más convenientes para la especie, aunque las zonas de mediana altitud (aproximadamente 2000 msnm) con estacionalidad climática también son sitios a considerar. En función de los resultados obtenidos, las actividades de conservación de la especie deberían concentrarse en localidades cercanas a Nabón, Girón y Saraguro, las cuales no han sido evaluadas... |
