A checklist of the scorpions of Ecuador (Arachnida: Scorpiones), with notes on the distribution and medical significance of some species J. Venom. Anim. Toxins incl. Trop. Dis.
Brito,Gabriel; Borges,Adolfo.
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...

A new species of Enyalioides (Iguanidae: Hoplocercinae) from southwestern Ecuador Pap. Avulsos de Zool. (São Paulo)
Torres-Carvajal,Omar; Almendáriz,Ana; Valencia,Jorge; Yánez-Muñoz,Mario; Reyes,Juan P..
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.

A pilot study on the identification of human papillomavirus genotypes in tongue cancer samples from a single institution in Ecuador BJMBR
Delgado Ramos,G.M.; Cotter,T.G.; Flor Ramos,L.; Torres Floril,V.; Ramos Martinez,G.A.; Ruiz-Cabezas,J.C..
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...

Architectural changes in larval leaf shelters of Noctuana haematospila (Lepidoptera: Hesperiidae) between host plant species with different leaf thicknesses Rev. Bras. Zool.
Greeney,Harold F.; Walla,Thomas R.; Lynch,Ryan L..
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...

Effectiveness of Integrated Pest Management Dissemination Techniques: A Case Study of Potato Farmers in Carchi, Ecuador AgEcon
Mauceri, Maria; Alwang, Jeffrey Roger; Norton, George W.; Barrera, Victor.
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...

Evaluación preliminar de las poblaciones de Pyrrhura orcesi en remanentes boscosos de la provincia de El Oro, Ecuador Hornero
Echeverría Vaca,Gabriela; Garzón Santomaro,César.
El Perico de El Oro (Pyrrhura orcesi) es una especie endémica de Ecuador que se encuentra en peligro de extinción. La principal amenaza para la especie es la fragmentación del hábitat. Se evaluó la abundancia de Pyrrhura orcesi en tres áreas no protegidas ubicadas en los bosques nublados de la provincia de El Oro mediante observaciones directas y registros auditivos en puntos fijos de conteo. El número máximo registrado para las tres áreas fue de 254 individuos. La abundancia relativa fue similar en las tres áreas. La abundancia no estuvo asociada con la cobertura de bosque. Los resultados del trabajo muestran el valor que tienen los remanentes boscosos en el área de estudio, en los cuales Pyrrhura orcesi puede persistir a pesar no tener ninguna protección.

Evaluating Safeguards in a Conservation Incentive Program: Participation, Consent, and Benefit Sharing in Indigenous Communities of the Ecuadorian Amazon Ecology and Society
Krause, Torsten; Lund University Centre of Excellence for Integration of Social and Natural Dimensions of Sustainability; torsten.krause@lucid.lu.se; Collen, Wain; International Institute for Industrial Environmental Economics; awcollen@gmail.com; Nicholas, Kimberly A.; Lund University Centre for Sustainability Studies; kimberly.nicholas.academic@gmail.com.
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...

Evaluation of DNA damage in an Ecuadorian population exposed to glyphosate Genet. Mol. Biol.
Paz-y-Miño,César; Sánchez,María Eugenia; Arévalo,Melissa; Muñoz,María José; Witte,Tania; De-la-Carrera,Gabriela Oleas; Leone,Paola E..
We analyzed the consequences of aerial spraying with glyphosate added to a surfactant solution in the northern part of Ecuador. A total of 24 exposed and 21 unexposed control individuals were investigated using the comet assay. The results showed a higher degree of DNA damage in the exposed group (comet length = 35.5 µm) compared to the control group (comet length = 25.94 µm). These results suggest that in the formulation used during aerial spraying glyphosate had a genotoxic effect on the exposed individuals.

Foreign market selection process as tool for international expansion: Case study for ecuadorian chia seeds exports to the european union Anais da ABC (AABC)
TERÁN-YÉPEZ,EDUARDO; SANTOS-ROLDÁN,LUNA; PALACIOS-FLORENCIO,BEATRIZ; BERBEL-PINEDA,JUAN MANUEL.
Abstract To assist Ecuadorian chia seed producers in their quest for internationalisation. This article uses a case study to present a methodology which assists in the selection of the most suitable export market for a product. It is based on a diverse range of indicators grouped into 7 dimensions that were used to analyse the 27 member countries of the European Union in order to determine the most suitable export market for chia seeds from Ecuador. Germany is the biggest European importer of chia seeds with a 55% share, followed by the Netherlands, the United Kingdom and Spain. It presents a methodology for market selection that can be employed as a tool for international expansion which can easily be used by companies in search of the most suitable...

Human papillomavirus infection and its association with cervical dysplasia in Ecuadorian women attending a private cancer screening clinic BJMBR
Brown,C.R.; Leon,M.L.; Muñoz,K.; Fagioni,A.; Amador,L.G.; Frain,B.; Tu,W.; Qadadri,B.; Brown,D.R..
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...

Influencing Factors of Infestation of Endo and Ectoparasites on Hair Sheep in Tropical Ecuador JARTS
Suárez, Victor; Tawfik, Ezzat S..
120 hair sheep were tested for faecal, skin and blood parasites. After three parasitological studies in humid Sucumbíos, it was proved that the parasitic charge is influenced by different factors. In the case of air temperature and humidity there was no variation detected between the seasons, although the parasitical charge rose in the course of this study. With regard to parasitic charge some systematic differences were found between the farming systems. Prophylactic measures such as rotational grazing, guarantee the food alternatives in the case of grass shortage, the strategic treatment with de-wormers and removal of excrement and garbage were recommended.

Is there a gender gap in housing? Marital property rights in Ecuador AgEcon
Twyman, Jennifer; Deere, Carmen Diana.
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...
