Abstract Our understanding of the plastic and evolutionary potential ectothermic organisms their populational impacts in face rapid global change remains limited. Studies attempting on relationship between magnitude thermal variability across latitude degree phenotypic plasticity exhibited by marine ectotherms are inconclusive. We state that latter arises from narrow range captured limited span latitudinal gradients studied to date. Using a mechanistic ecophysiological approach...
Vector transmission of Trypanosoma cruzi appears to be interrupted in Chile; however, data show increasing incidence Chagas' disease, raising concerns that there may a reemerging problem.To estimate the actual risk changing world it is necessary consider historical vector distribution and correlate this with presence cases climate change.Potential models Triatoma infestans Chagas disease were performed using Maxent, machine-learning method.Climate change play major role reemergence T. Chile....
Introduction: Biodiversity is inextricably linked to human health. As an important area of research the Convention on Biological Diversity and a key avenue for dissemination biodiversity health knowledge, we investigated how well-embedded interlinkages are in institutional higher education offerings. Methods: Using One Health programs as starting point, collected global list institutions potentially carrying out links between through previously published research, academic partners...
In this study we hypothesized that Grammostola rosea Walckenaer 1837, an active predator of large size depends on its two paired book lungs for respiration, would have a refined low energy strategy based thin air-hemolymph barrier. The morphology and the oxygen consumption at 20° 30° C under normal starvation conditions were studied. was compared to expected spiders from allometric relationship, 0.027 ± 0.01 ml O2 g−1 h−1 (average standard deviation), it depressed starvation. harmonic mean...
We characterize, in both the laboratory and field, preferential thermal microenvironments of Paraphysa parvula (Pocock 1903) (Araneae: Theraphosidae), a mygalomorph spider that successfully inhabits high elevation environments Chilean Andes. studied 116 spiders. Their average body temperature field was 31.02 ± 2.74° C, similar to preferred 31.7 2.31° higher than ideal reproductive females, 29.34 2.81° C. In non-reproductive spiders, we found significant associations between temperatures air,...
Variations in the preferred temperatures during rest periods of Grammostola rosea Walckenaer and Paraphysa parvula Pocock, two mygalomorph spiders occupying different habitats central Chile, are analyzed. The former inhabits arid semi‐arid lowland near plant communities, composed shrubs (evergreens with small leathery leaves) trees; latter is found mountains Chilean Andes, above 2000 m.a.s.l. these at times day exposure to cold (15 °C) warm (25 acclimation compared. Body mass does not affect...
We studied structure and function of the respiratory system in bat Tadarida brasiliensis compared it with those two species rodents, Abrothrix andinus A. olivaceus. had lower resting oxygen consumption, but higher maximum consumption aerobic scope, than rodents. The blood-gas barrier was thinner its relative lung size larger; however, alveolar surface density similar among three species. In consequence, T. has an diffusion capacity or times that characteristics were accompanied by...
Background Central obesity has a higher risk of the metabolic syndrome (MetS) and cardiovascular diseases. It is estimated by measuring waist circumference (WC) waist-to-hip ratio (WHR), which are operator-dependent. The present study aimed to validate body composition monitor (BCM) as tool for estimating visceral adipose tissue (VAT), well assess its capacity predict MetS correlation with anthropometric parameters. Methods We measured WC, WHR mass index (BMI) in 60 recruited subjects. BCM...
Hematological parameters of birds and mammals seem to respond environmental requirements, such as hypoxia at high altitude the energetic demands locomotion flight.In this work we hypothesize that lung capillary hematocrit red blood size may be influenced by requirements flight.Also, propose hematological should vary together with morphological determine oxygen diffusion capacity.We analyzed cell local characteristics pulmonary correlating these factors determines deal seven species,...
We studied the lung diffusion parameters of two species birds and mammals to explore how structural functional features may be paralleled by differences in life style or phylogenetic origin.We used fast-flying (one mammal one bird), running bird that flies only occasionally as models.The harmonic mean thickness air-blood barrier was very thin we studied.An exception Chilean tinamou Notoprocta perdicaria, which occasionally.It showed an thick flightless Galliformes.We found respiratory...
Epidemiological dynamics of dengue on Easter IslandDengue is considered an emerging disease with increasing prevalence especially in South America.In 2002, epidemic classic Dengue (DENV-1) occurred unexpectedly Island, where it had never been detected before.It reappeared 2006-2007 and 2008, 2009 2011.The aim this study was to estimate the most relevant parameters epidemiological transmission Island model since comparing predictions actual situation observed.Of total cases, 52.27% were...
Climate change affects the dynamics of vector-borne diseases. Culex pipiens Linnaeus is main vector West Nile fever; a widely distributed arbovirus, it continuously increasing its distribution. Using species distribution model, maps suitable habitats Cx. were generated for Chile in current climate and three scenarios, using global regional georeferenced presence records as input, plus bioclimatic variables. Since this virus has not yet arrived Chile, purpose study to anticipate potential...
In this contribution we studied the developmental phenotypic plasticity of respiratory structures involved in exchange gases an altricial rodent, leaf-eared mouse (Phyllotis darwini).We morphological pulmonary parameters warm (30 °C) and cold acclimated animals 15 at different stages.We found that acclimation treatments did not affect neither lung volume, alveolocapillary barrier thickness nor surface density.In consequence oxygen diffusion capacity was affected.Although Phyllotis darwini...
: Zoonotic diseases represent 60% of the infections suffered by human species. in light latest episodes epidemics and pandemics we have to begin address health problems with another perspective. The "One Health" vision aims generate a change consciousness new working strategy.
In this report, we explore the matching of structures to functional needs by comparing previously reported data maximal oxygen consumption and development lung in leaf-eared mouse Phyllotis darwini warm cold environments.We discuss whether state structural design is commensurate with from regulated morphogenesis as predicted hypothesis symmorphosis.We found a close match between respiratory during postnatal development, expressed safety factors unity.However, adult stage were greater than...
