Two new species of the caddisfly genusCernotinaRoss, 1938 (Polycentropodidae) are described from the lowland Amazon basin of Ecuador,Cernotina tiputini, new species, andCernotina waorani, new species. These represent the first new species described from this region. We also record from Ecuador for the first timeCernotina hastilisFlint, previously known from Tobago, and present new Ecuadorian locality records forC.cygneaFlint, andC.lobisomemSantos & Nessimian. The homology of the intermediate appendage of the male genitalia of this genus is established. The region surveyed is under severe e

Abstract:

Neoliberal reforms throughout Latin America are intended to promote development by opening up economies and encouraging market-oriented practices. These reforms have deeply affected the lives of indigenous peoples and their relationship with extralocal actors. Today, in the Ecuadorian Amazon, some indigenous peoples participate in oil-extraction negotiations, tourism, and intensive cattle ranching and agriculture as part of increased market integration. In the midst of these changes, questions about what ‘indigeneity’ means, both in integrating into and in resisting neoliberal reforms, are inc

Abstract:

This paper draws upon a detailed longitudinal survey of households living on agricultural plots in the northern three provinces of the Ecuadorian Amazon, the principal region of colonization by migrants in Ecuador since the 1970s. Following the discovery of petroleum in 1967 near what has subsequently come to be the provincial capital and largest Amazonian city of Lago Agrio, oil companies built roads to lay pipelines to extract and pump oil across the Andes for export. As a result, for the past 30 years over half of both Ecuador's export earnings and government revenues have come from petrole

ABSTRACT This paper examines changes over time for a full generation of migrant settlers in the Northern Ecuadorian Amazon (NEA). Data were collected from a 2014 household survey covering a subsample of households surveyed previously in 1990 and 1999. We observed changes in demographic behavior, land use, forest cover, and living conditions. As the frontier develops, human fertility is continuing to decline with contraceptive prevalence rising. Meanwhile, out-migration from colonist households, largely to destinations within the region, persists. More households have secure land tenure than in

Deforestation by human activities is a common issue in Amazonian countries. This occurs at different spatial and temporal scales causing primary forest loss and land fragmentation issues. During the deforestation process as the forest loses connectivity, the deforested patches create new intricate connections, which in turn create complex networks. In this study, we analyzed the local connected fractal dimension (LCFD) of the deforestation process in the Sumaco Biosphere Reserve (SBR) with two segmentation methods, —CA-wavelet and K-means—to categorize the complexity of deforested patches’ con

As a result, there is likely considerable spillover across country borders, particularly along the border between Peru and Ecuador.

Abstract:

The northernmost Peruvian Andes, a unique biogeographic region characterized by the confluence of multiple distinct ecosystems (i.e. Amazon basin, Pacific rainforest, the Sechura Desert, the northern and central Andes), is the southernmost geographic range limit of the South American shrews representing the genus Cryptotis. In the northernmost Peruvian Andes, two poorly known species have traditionally been reported (C. peruviensis and C. equatoris). Our study, based on molecular and morphologic traits, confirms the presence of C. peruviensis but also the occurrence of C. montivaga, based on s

Abstract:

Conservation and sustainable development of forests are mitigation mechanisms against climate change due to the forest carbon sink capacity. Therefore, biomass estimation allows to assess forest productivity and control carbon budgets. In Ecuador, biomass and carbon sequestration studies are scarce. Thus, we estimated and forecasted changes in biomass of Ecuadorian forests through the Mathematical Spatial Model of Global Carbon Cycle and the Normalized Differential Vegetation Index. The mathematical model describes the processes of growth and decay of vegetation in terms of carbon exchange bet

El artículo hace un balance sobre los aspectos principales que se deducen del proceso de expansión de la frontera agrícola en la Amazonía ecuatoriana con énfasis en el nororiente en donde se desarrollan actividades de explotación petrolera desde la década de 1960. Tal proceso, al igual que la colonización, junto con el ingreso de las empresas agroindustriales y madereras tuvo como trasfondo el discurso oficial de la “Amazonía como territorio vacío”. Plantea además, el papel que ha jugado la reproducción de las economías campesinas en la expansión del capital y, consecuentemente, en la integrac

Abstract:

Adequate environmental management in tropical aquatic ecosystems is imperative. Given the lack of knowledge about functional diversity and bioassessment programs, management is missing the needed evidence on pollution and its effect on biodiversity and functional ecology. Therefore, we investigated the composition and distribution of the macroinvertebrate community along two rivers. Specifically, 15 locations were sampled in the Coca and Aguarico Rivers (Ecuadorian Amazon) and the macroinvertebrates were used to indicate water quality (WQ), expressed as the Biological Monitoring Working Party

Extending a bare hand dripping with crude, he launched La Mano Sucia de Chevron campaign, demanding accountability for decades of contamination. This article explores the role of bodily knowledge in witnessing industrial contamination and struggles for environmental justice. Situating the mano sucia in the history of activism in the region, I show how the juxtaposition of different hands within the same motif reveals profoundly asymmetric relationships to the toxic entanglements

Abstract The Ecuadorian Andes are characterized by a complex spatiotemporal variability of precipitation. Global circulation models do not have sufficient horizontal resolution to realistically simulate the complex Andean climate and in situ meteorological data are sparse; thus, a high-resolution gridded precipitation product is needed for hydrological purposes. The region of interest is situated in the center of Ecuador and covers three climatic influences: the Amazon basin, the Andes, and the Pacific coast. Therefore, regional climate models are essential tools to simulate the local climate

Abstract:

In the Amazon Rainforest, a unique post-carbon plan to mitigate global warming and to protect the exceptional bio-cultural diversity was experimented in 2007–2013 by the Ecuadorian government. To preserve the rainforest ecosystems within the Yasuní-ITT oil block, the release of 410 million metric tons of CO2 would have been avoided. The neologism “yasunization” emerged as an Amazonian narrative on “unburnable carbon” to be replicated worldwide. Considering the unburnable carbon, petroleum-associated gas flaring represents the unleakable part. Flaring is an irrational practice that consists of

The results obtained suggest a moderately low degree of genetic diversity (He = 0.396).

Precipitation monitoring is of utmost importance for water resource management. However, in regions of complex terrain such as Ecuador, the high spatio-temporal precipitation variability and the scarcity of rain gauges, make difficult to obtain accurate estimations of precipitation. Remotely sensed estimated precipitation, such as the Multi-satellite Precipitation Analysis TRMM, can cope with this problem after a validation process, which must be representative in space and time. In this work we validate monthly estimates from TRMM 3B43 satellite precipitation (0.25° x 0.25° resolution), by us
