Paul O Guillen, Karla B Jaramillo, Gregory Genta-Jouve, Frederic Sinniger, Jenny Rodriguez, Olivier P Thomas
The first chemical study of the common species Terrazoanthus onoi, present off the coast of Ecuador, led to the identification of a new family of 2-aminoimidazole alkaloids named terrazoanthines A-C (1-3). Homologues 1 and 2 feature an unprecedented 6-(imidazol-5-yl)benzo[d]imidazole. Acyl substitution pattern and complete configurational assignments were deduced from comparison between experimental and theoretical (13)C NMR and ECD data, respectively. These compounds may represent key derivatives in the biosynthesis of zoanthoxanthins...

Caroline Sayuri Fukushima, Rogério Bertani
The genus Avicularia Lamarck, 1818 is revised and all species are rediagnosed. The type species, described as Aranea avicularia Linnaeus, 1758, is the oldest mygalomorph species described and its taxonomic history is extensive and confusing. Cladistic analyses using both equal and implied weights were carried out with a matrix of 46 taxa from seven theraphosid subfamilies, and 71 morphological and ecological characters. The optimal cladogram found with Piwe and concavity = 6 suggests Avicularia and Aviculariinae are monophyletic...

Geographic barriers and elevational gradients have long been recognized as important in species diversification. Here, we illustrate an example where both mechanisms have shaped the genetic structure of the Neotropical rainfrog, Pristimantis ornatissimus, which has also resulted in speciation. This species was thought to be a single evolutionary lineage distributed throughout the Ecuadorian Chocó and the adjacent foothills of the Andes. Based on recent sampling of P. ornatissimus sensu lato, we provide molecular and morphological evidence that support the validity of a new species, which we name Pristimantis ecuadorensis sp...

The Galapagos sea lion ( Zalophus wollebaeki ), an endangered species, experiences high pup mortality (up to 100%) in years when El Niño events reduce food supply in the Galapagos Islands. Mortality of pups in non-El Niño years is estimated to be 5% in undisturbed colonies. From 2009 to 2012 we observed high pup mortality (up to 66%) in colonies close to the Galapagos capital, Puerto Baquerizo Moreno, where contact with humans, domestic animals, and rats is frequent. Gross postmortem findings from 54 pups included hemorrhagic lesions in liver and congestion in lungs; histopathology suggested a possible association with infectious diseases...

Female preference for local cultural traits has been proposed as a barrier to breeding among animal populations. As such, several studies have found correlations between male bird song dialects and population genetics over relatively large distances. To investigate if female choice for local dialects could act as a barrier to breeding between nearby and contiguous populations, we tested if variation in male song dialects explains genetic structure among eight populations of rufous-collared sparrows (Zonotrichia capensis) in Ecuador...

The goal of sustainable intensification of agriculture in Malawi has led to the evaluation of innovative, regionally novel or under-utilized crop species. Quinoa (Chenopodium quinoa Willd.) has the potential to provide a drought tolerant, nutritious alternative to maize. We evaluated 11 diverse varieties of quinoa for their yield and agronomic performance at two locations, Bunda and Bembeke, in Malawi. The varieties originated from Ecuador, Chile and Bolivia in South America; the United States and Canada in North America; and, Denmark in Europe, and were chosen based on their variation in morphological and agronomic traits, and their potential for adaptation to the climate of Malawi...

Socioeconomic status (SES) is known to have a considerable influence on the development of neuropsychological functions. In particular there is strong evidence for less efficient development of prefrontal-cortex-related functions in children raised in low-SES households. "Street children" are a common feature of low SES in many low- and middle-income countries, and some researchers have suggested that the unique life experiences of street children may drive their neurocognitive development. This study compares a group of 36 former street children in Quito, Ecuador with a control group of 26 never street-connected schoolchildren...

Payment for Environmental Service programs are increasingly applied in communal settings where resource users collectively join the program and agree to limit their shared use of a common-property resource. Who decides to join PES and the degree to which community members agree with the collective decision is critical for the success of said programs. Yet, we have limited understanding of the factors that influence communal participation and the collective decision process. This paper examines communal participation in a national payment for conservation program in Ecuador...
