(Wiley, 2020)1. Blood-feeding bugs in the Triatominae are the vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. Mepraia is a sylvatic genus endemic to Chile that transmits T. cruzi in the wild cycle. 2. ...
-
(ELSEVIER, 2006-07)Parasites have been shown to manipulate the feeding behaviour of their invertebrate vectors, which results in an increased probability of transmission to definitive hosts. Most evidence for this hypothesis comes from ...
-
(BLACKWELL PUBLISHING, 2008-03)Parasites can reduce host fitness through short-term mortality, complete or partial castration, or slight reductions in host fecundity. Hosts may reduce reproductive effort as an adaptive strategy to tolerate parasitism. ...
-
(FUNDACO OSWALDO CRUZ, 2005-05)Molecular evidence showed 46.2% of Trypanosoma cruzi infection in Mepraia spinolai insects from North-Central Chile, which is significantly higher than previous reports of up to 26% by microscopic observation. Our results ...
-
(Blackwell Publishing Ltd, 2014)© 2014 The Royal Entomological Society. Several reports have described host species diversity and identity as the most important factors influencing disease risk, producing either dilution or amplification of the pathogen ...
-
(Elsevier, 2016)Hematophagous insects of the subfamily Triatominae include several species with a large variety of shapes, behavior and distribution. They have great epidemiological importance sincemost of themtransmit the flagellated ...
-
(Taylor & Francis, 2015)In this study, we report the first record of mites of the genus Leptus (Latreille, 1796) (Trombidiformes: Erythraeidae) found on the triatomine Mepraia spinolai (Maza, Gajardo and Jorg, 1940) (Hemiptera: Rudiviidae), one ...
-
(Springer, 2014)Habitat fragmentation and degradation are important biodiversity change drivers worldwide. Their effects have been described for many animal groups, but little is known about marsupials. We conducted a meta-analysis ...
-
(BLACKWELL, 2007-12)We describe the geographical variation of corolla and nectar guide size in seven populations of Mimulus luteus (Phrymaceae) in central Chile, and examine whether flower phenotypes associate with taxonomic composition and ...
-
(MARY ANN LIEBERT, 2016)Chagas disease, which ranks among the world's most neglected diseases, is a chronic, systemic, parasitic infection caused by the protozoan Trypanosoma cruzi. Mepraia species are the wild vectors of this parasite in Chile. ...
-
(Nature, 2020)Studies of host-parasite relationships largely benefit from adopting a multifactorial approach, including the complexity of multi-host systems and habitat features in their analyses. Some host species concentrate most ...
-
(Springer, 2013)Masking, a type of camouflage, has been argued to function as an antipredator mechanism helping to avoid detection or recognition by a prey or predator. However, research focused on the effects of masking on life history ...
-
(Wildlife Disease Assoc, Inc., 2017)We report natural infections by pathogenic Leptospira of two rodent species endemic to Chile: the degu (Octodon degus) and Darwin's pericote (Phyllotis darwini). We detected Leptospira DNA in kidney and urine samples taken ...
-
Nonadditive effects of flower damage and hummingbird pollination on the fecundity of Mimulus luteus (SPRINGER, 2006-10)Flower herbivory and pollination have been described as interactive processes that influence each other in their effects on plant reproductive success. Few studies, however, have so far examined their joint effects in ...
-
(Elsevier, 2020)Chagas disease is a public health problem in America. Its parasite, Trypanosoma cruzi, presents different discrete typing units (DTUs), colonizes organs of mammalian hosts in chronic infections, and presents tropism for ...
-
(Elsevier, 2015)Parasite-mediated behavioral changes in their hosts have been documented in many species, but field evidence is scarce. The protozoan Trypanosoma cruzi is transmitted by insect vectors to several mammal species. Although ...
-
(Mary Ann Liebert, 2013)In this study, we performed a phylogenetic analysis of 35 species of the tribe Triatomini by means of available 16S ribosomal DNA and cytochrome b (Cyt b) gene sequence data, adding taxa of the spinolai complex, to ...
-
(The Royal Society, 2020)Vector-borne infectious disease dynamics result mainly from the intertwined effect of the diversity, abundance, and behaviour of hosts and vectors. Most studies, however, have analysed the relationship between host-species ...
-
(ELSEVIER SCIENCE BV, 2005-08)n this study, we quantify the home range of Mepraia spinolai, a wild vector of Trypanosoma cruzi, and the abundance of wild mammals during summer and winter seasons in a protected area of north-central Chile. Results ...
-
(Wiley, 2017-05)The influence of parasites on host reproduction has been widely studied in natural and experimental conditions. Most studies, however, have evaluated the parasite impact on female hosts only, neglecting the contribution ...
