    Abstract Estudios sobre alianzas electorales subrayan a la hegemonía política, erosión y ciclo electoral como determinantes para la generación de alianzas antihegemónicas. No obstante, en elecciones para renovar las gubernaturas aparecen las condiciones enunciadas sin el resultado esperado. ¿Qué factores lo inhiben? Se argumenta que la no concurrencia local, escasas elecciones simultáneas y la nacionalización electoral impiden la formación de este tipo de alianzas. Para probarlo se seleccionó al Estado de México como un ejemplo de caso negativo, y desde un enfoque de estudio de caso se comparó transversal y longitudinalmente. El objetivo es revelar los condicionantes que de forma sistemática inhiben la formación de la alianza antihegemónica. Los hallazgos son el predominio de alianzas oficialistas, la ausencia de cargos para la negociación antihegemónica y mayor dependencia nacional de recursos. Se concluye que el ciclo electoral y la dimensión política de la entidad incrementan la nacionalización de la contienda.

    Abstract Mientras los estudios afirman la fuerte restricción de los candidatos independientes debido a su escaso éxito electoral, este documento argumenta que los requisitos menos restrictivos y la experiencia política favorecen las candidaturas independientes. Para demostrarlo, se clasifican los 31 estados por nivel de restricción, se revisan la proporción de aspirantes y candidatos independientes por nivel, y se indaga la experiencia política de los 97 aspirantes para las gubernaturas de México, entre 2015 y 2018. Los hallazgos principales son: 1) el predominio de entidades con bajo nivel restrictivo que presentan la mayor proporción de aspirantes y candidaturas logradas y 2) el predominio de candidatos con experiencia política.

  4. Article: Local ecological knowledge reveals combined landscape effects of light pollution, habitat loss, and fragmentation on insect populations

    Abstract Recent reports of drastic declines in insect populations have raised global concerns about their conservation. Light pollution is a near inseparable feature of human-altered landscapes and is a potential contributing factor to insect declines. However, despite the wide recognition of the deleterious effects of lights on insects, whether these effects scale up to impact insect populations remains unclear. Here, we relied on a combination of ecological niche modeling, geographical information systems, and interviews on local ecological knowledge to assess the synergistic effects of landscape light pollution and habitat loss and fragmentation on populations of the Chocó golden scarab Chrysina argenteola. Sightings of C. argenteola by locals revealed individuals are scarcer in areas with reduced forest cover and rely on inter-patch dispersal to cope with habitat fragmentation, where they were constantly attracted to urban lights. Increasingly lit landscapes had more individuals attracted to lights, but the opposite was true in areas with less than 4 km² of remaining forest cover. We suggest this pattern arises as landscape light pollution intercepts individuals during inter-patch dispersal. This hinders habitat connectivity, potentially disrupting metapopulation dynamics, being populations inhabiting areas with scarce fragmented habitat more vulnerable to this process. We show light pollution acts in combination with habitat loss and fragmentation in detriment of insect populations at the landscape scale.

    Abstract We explore the effect of roads in animal mortality within the Biodiversity Hotspot with the highest number of endemic species of vertebrates on Earth, the Tropical Andes. Our objectives were to know which species are killed on roads in this particularly biodiversity‐rich area and how landscape composition and configuration influences roadkills. We systematically looked for roadkills along roads that border three protected areas in the Ecuadorian Andes. To evaluate our hypotheses, we used correlation, logistic regression, and GIS analyses. We surveyed a total of 7128 km and observed a roadkill rate of 6.24 (95% CI = 5.35–7.14) individuals per 100 km/day. Roadkills included poorly known endemic and endangered vertebrates; among them, one undescribed snake species of the genus Atractus. Most roadkills were by pastures, the dominant vegetation by roads in our study area. Roadkills were more likely to occur near bridges and were more frequent at greater distances from natural vegetation, towns, and rivers. We conclude that pastures and bridges may be functioning as ecological traps for small and poorly known vertebrates. Mitigation measures could include increasing road permeability to wildlife by constructing culverts in critical points where mortality is high, and the adaptation of areas beneath bridges for them to function effectively as wildlife underpasses. These measures should be complemented with fences to exclude vertebrates from roads in areas near wildlife passages and along pastures. We encourage the development of similar studies in biodiversity‐rich areas to inform mitigation measures that can be adapted to local conditions. Abstract in Spanish is available with online material.

    Abstract Este artículo parte de las tensiones metodológicas registradas en la literatura reciente sobre alianzas electorales entre estudios cuantitativos y los registros empíricos de elecciones donde no se cumplen las expectativas teóricas. Buscando encontrar las razones de esta anomalía, se propone identificar los factores que inhiben el efecto de las variables independientes -los llamados mecanismos causales-, a partir de estudios de caso. En este sentido, el artículo expone el giro metodológico al respecto, previa revisión de las limitaciones de los estudios cuantitativos y la necesidad de complementarlos desde una aproximación cualitativa. Mediante un ejemplo de selección intencionada de observaciones, se visualiza la riqueza del ejercicio metodológico para posteriores estudios. Se concluye que los casos típicos, atípicos, de contraste típico-atípico y de máxima variación pueden afinar el conocimiento sobre los mecanismos y condiciones que posibilitan las alianzas electorales.

    Abstract Los efectos positivos de la reelección consecutiva son la mayor profesionalización de los políticos, la reducción de la brecha entre el político y el ciudadano, y el incremento de la rendición de cuentas de los representantes, cuando se introduce como regla en los sistemas político-electorales; sin embargo, dichos beneficios requieren ciertas condiciones que están ausentes en el caso mexicano. En la presente colaboración se reflexiona sobre las implicaciones causales de la teoría sobre la reelección consecutiva con mecanismos que median como catalizadores adversos, productos de la específica transición democrática en México. En este sentido, el análisis se concentra en discutir la posibilidad de un fortalecimiento del control partidista y el debilitamiento del vínculo entre representantes y representados. / The positive effects of consecutive re-election are the further professionalization of politicians’ careers, the diminishing of the gap between politician and citizens, and the increase of representatives’ accountability when introduced as a regulation in political-electoral systems. Nevertheless, such advantages demand certain conditions not present in the Mexican case. This article ponders the causal implications of the theory of consecutive re-election in the face of mechanisms that mediate as adverse catalyzers, a consequence of the peculiarities of democratic transition in Mexico. Thus, this analysis focuses on discussing the possibility of a strengthening of party control and a weakening of the link between representatives and those represented.

    Abstract This article contains data of the horizontal hydraulic conductivity of five different fine-grained soils of the former Lake Texcoco. The data were back-calculated from excess pore pressure dissipation measurements collected at 119 locations using piezocone tests (CPTu). The test campaign was part of the geotechnical survey performed for the construction of the New Mexico City International Airport (NAICM). Descriptive statistical parameters of each soil unit are presented and lognormal probability distributions are fitted to describe the natural variability of the horizontal hydraulic conductivity of this site.

    Abstract Roads are a main threat to biodiversity conservation in the Amazon, in part, because roads increase access for hunters. We examine how increased landscape access by hunters may lead to cascading effects that influence the prey community and abundance of the jaguar (Panthera onca), the top Amazonian terrestrial predator. Understanding such ecological effects originating from anthropogenic actions is essential for conservation and management of wildlife populations in areas undergoing infrastructure development. Our study was conducted in Yasuní Biosphere Reserve, the protected area with highest potential for jaguar conservation in Ecuador, and an area both threatened by road development and inhabited by indigenous groups dependent upon bushmeat. We surveyed prey and jaguar abundance with camera traps in four sites that differed in accessibility to hunters and used site occupancy and spatially explicit capture-recapture analyses to evaluate prey occurrence and estimate jaguar density, respectively. Higher landscape accessibility to hunters was linked with lower occurrence and biomass of game, particularly white-lipped peccary (Tayassu pecari) and collared peccary (Pecari tajacu), the primary game for hunters and prey for jaguars. Jaguar density was up to 18 times higher in the most remote site compared to the most accessible site. Our results provide a strong case for the need to: 1) consider conservation of large carnivores and other wildlife in policies about road construction in protected areas, 2) coordinate conservation initiatives with local governments so that development activities do not conflict with conservation objectives, and 3) promote development of community-based strategies for wildlife management that account for the needs of large carnivores.
