One of the main problems in the production of cacao in Ecuador is the disease caused by the fungus Moniliophthora roreri (frosty pod rot) which affects the pods. Here, we evaluate the genetic diversity of this fungus in Ecuador, and its sensitivity to the fungicide azoxystrobin. We evaluated 76 monosporic cultures from the Amazon and the Pacific co...

The Andean cloud forests of Ecuador are home to several endemic mammals. Members of the Thomasomyini rodents are well represented in the Andes, with Thomasomys being the largest genus (47 species) of the subfamily Sigmodontinae. Within this tribe, however, there are genera that have escaped a taxonomic revision, and Chilomys Thomas, 1897, constitut...

Full-text available
Basic diversity studies of small non-volant mammals are scarce in western Ecuador, evidenc-ing a knowledge gap regarding the mammalian fauna in the region. These organisms play key roles in important ecological processes and may be affected by several anthropogenic factors. Herein we report the results of a rapid assessment of marsupials and rodent...

Full-text available
Trypanosoma brucei and T. cruzi are parasites of medical interest because of the diseases they cause in humans and domestic mammals. However, these and many more species of trypanosomes also infect wild mammals, and their study is important to: 1) understand the overlap between domestic and sylvatic transmis- sion cycles; 2) comprehend the evolutio...

The species within Xenarthra (sloths, anteaters, and armadillos) are quintessential South American mammals. Of the three groups, Vermilingua (anteaters) contains the fewest extant and paleontological species. Here, we sampled and sequenced the entire mitochondrial genomes (mitogenomes) of two Tamandua species (Tamandua tetradactyla and Tamandua mex...

Water bodies and aquatic ecosystems are threatened by discharges of industrial waters. Ecotoxicological effects of components occurring in untreated and treated wastewaters are often not considered. The use of a linear, multi-compartmented, non-forced, static system constructed with PET bottles is proposed for the quality assessment of treated wate...
Article
Full-text available
Didelphis species have been shown to exhibit very conservative karyotypes, which mainly differ in their constitutive heterochromatin, known to be mostly composed by repetitive DNAs. In this study, we used genome skimming data combined with computational pipelines to identify the most abundant repetitive DNA families of Lutreolina crassicaudata and...
Chapter
Full-text available
Geographical assignment of individuals, or tissues, seized from illegal traffic and hunting is relevant for the conservation of many species. For this, the real number of genetically differentiated groups within a species should be determined to know from where the specimens were illegally extracted or to know where the seized and rehabilitated spe...
Article
Full-text available
Understanding the blood meal patterns of insects that are vectors of diseases is fundamental in unveiling transmission dynamics and developing strategies to impede or decrease human–vector contact. Chagas disease has a complex transmission cycle that implies interactions between vectors, parasites and vertebrate hosts. In Ecuador, limited data on h...

Article
Full-text available
Opossums of the genus Didelphis comprise six species representing the largest American marsupials. Although the monophyly of the species of the genus, as well as that of the genus itself, is well supported in most phylogenetic studies, the relationships among those species are not yet understood. In this study, we present the complete mitochondrial...
Article
Full-text available
The Andean cloud forests of western Colombia and Ecuador are home to several endemic mammals; members of the Oryzomyini, the largest Sigmodontinae tribe, are extensively represented in the region. However, our knowledge about this diversity is still incomplete, as evidenced by several new taxa that have been described in recent years. Extensive fie...

Conference Paper
For centuries biologists and naturalists have published, morphological information of animals and plants in printed media such as books and journals. However, only a small fraction of that information is easily available and formatted to conduct further phylogenetic analysis. It is necessary to develop software tools to extract, integrate and publi...
Article
Full-text available
A first step in protecting groups of similarly structured organisms is to place them into discrete taxa. Molecular genetics and phylogeny allow us to rebuild the evolutionary history of these taxa. The Neotropics has roughly 34% of Earth’s primate diversity. However, the systematics of Neotropical primates is complex and controversial. The untufted...

Abstract Background: The white-naped squirrel, Simosciurus nebouxii (previously known as Sciurus stramineus), has recently been identified as an important natural host for Trypanosoma cruzi in Ecuador. The nests of this species have been reported as having high infestation rates with the triatomine vector Rhodnius ecuadoriensis. The present study a...

Full-text available
The Andes Mountains particularly the forests along the mid-elevations of their eastern and western slopes, are a hotspot of biodiversity (high numbers of species and endemics). Among mammals, rodents are a priority group for study in the Tropical Andes given their high diversity and often relatively small geographic ranges. Here, we use DNA barcodi...

A finales del siglo XX, el naturalista Daniel Janzen en una conferencia transmitió una idea novedosa. Las palabras exactas se perdieron, pero unos colegas que oyeron al Dr. Janzen parafrasean: "yo quiero que un día todas las especies del mundo puedan identificarse usando una cajita que quepa en la palma de mi mano" ¿Se pueden imaginar? Janzen inclu...

Habitat disturbance and anthropogenic change are globally associated with extinctions and invasive species introductions. Less understood is the impact of environmental change on the parasites harbored by endangered, extinct, and introduced species. To improve our understanding of the impacts of anthropogenic disturbance on such host-parasite inter...

Trypanosomes are a diverse group of protozoan parasites of vertebrates transmitted by a variety of hematophagous invertebrate vectors. Anuran trypanosomes and their vectors have received relatively little attention even though these parasites have been reported from frog and toad species worldwide. Blood samples collected from túngara frogs (Engyst...

Background: Bat trypanosomes are implicated in the evolution of the T. cruzi clade, which harbours most African, European and American trypanosomes from bats and other trypanosomes from African, Australian and American terrestrial mammals, including T. cruzi and T. rangeli, the agents of the American human trypanosomiasis. The diversity of bat try...

Full-text available
Trypanosoma rangeli is a nonpathogenic parasite for humans; however, its medical importance relies in its similarity and overlapping distribution with Trypanosoma cruzi, causal agent of Chagas disease in the Americas. The genetic diversity of T. rangeli and its association with host species (triatomines and mammals) has been identified along Centra...

The Trypanosoma cruzi clade is a group of parasites that comprises T. cruzi sensu lato and its closest relatives. Although several species have been confirmed phylogenetically to belong to this clade, it is uncertain how many more species can be expected to belong into this group. Here, we present the results of a survey of trypanosome parasites of...

We provide the first evidence of Hepatozoon parasites infecting bats. We sequenced a short fragment of the 18S rRNA gene (~600 base pairs) of Hepatozoon parasites from 3 Hipposideros cervinus bats from Borneo. Phylogenies inferred by model-based methods place these Hepatozoon within a clade formed by parasites of reptiles, rodents, and marsupials....

Where does a species live? How common is it? Where does it spend its inactive periods? These are basic questions about the biology of a species, which bring key information for application in conservation and management. Unfortunately, this information is available for only a minimum fraction of all animal species. Using 1) ecological niche modelin...

We report TcBat, a recently described genetic lineage of Trypanosoma cruzi, in fruit-eating bats Artibeus from Panama. Infections were common (11.6% prevalence), but no other T. cruzi cruzi genotypes were detected. Phylogenetic analyses show an unambiguous association with Brazilian TcBat, but raise questions about the phylogenetic placement of thi...
