Beta diversity along an elevational gradient at the pico da neblina (Brazil): Is spider (arachnida-araneae) community composition congruent with the guayana region elevational zonation?
(2021-12-01)
Beta diversity is usually high along elevational gradients. We studied a spider community at the Pico da Neblina (Brazil), an Amazonian mountain which is one of the southern components of the Guayana region. We sampled six ...
High speed elevator dynamic analysis and control on severe conditions
(2020-01-01)
The advent of verticalization after WWII made the densification on major cities. Thus the high-rise building was the solution to accommodate the vast amount of people on cities. The elevator was a solution to vertical ...
Genetic and phenotypic variation, dispersal limitation and reproductive success in the invasive herb Eschscholzia californica along an elevation gradient in central Chile
(2017)
Background: Reductions of genetic diversity and phenotypic changes in invasive plants are often observed to occur at high elevations. Genetic/phenotypic changes of invasive plants along elevation help to understand mechanisms ...
Phylogeny of Chaetanthera (Asteraceae : Mutisieae) reveals both ancient and recent origins of the high elevation lineages
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-12)
Penalized likelihood analysis of previously published chloroplast DNA (cpDNA) ndhF sequences suggests that the central-southern Andean genus Chaetanthera diverged ca. 16.5 million years (my) ago, well before the uplift of ...
Genetic and phenotypic variation, dispersal limitation and reproductive success in the invasive herb Eschscholzia californica along an elevation gradient in central Chile
(Taylor & Francis, 2017)
Background: Reductions of genetic diversity and phenotypic changes in invasive plants are often observed to occur at high elevations. Genetic/phenotypic changes of invasive plants along elevation help to understand mechanisms ...
Genetic diversity and gene flow decline with elevation in montane mayflies
(Nature Publishing Group, 2017-08-01)
Montane environments around the globe are biodiversity 'hotspots' and important reservoirs of genetic diversity. Montane species are also typically more vulnerable to environmental change than their low-elevation counterparts ...
Energy storage, body size and immune response of herbivore beetles at two different elevations in Costa Rica
(Universidad de Costa Rica, 2019)
Manual thrombus aspiration in patients with ST-elevation myocardial infarction with high thrombus burden and a total ischemic time greater or equal than 3 hours: Mini Review.
(Elsevier, 2023)
Manual Thrombus Aspiration (MTA) reduces thrombus burden and improves myocardial reperfusion markers in patients with ST-segment elevation myocardial infarction (STEMI), however its clinical benefit is controversial due ...
Functional role of long-lived flowers in preventing pollen limitation in a high elevation outcrossing species
(Oxford university press, 2017)
Low pollinator visitation in harsh environments may lead to pollen limitation which can threaten population persistence. Consequently, avoidance of pollen limitation is expected in outcrossing species subjected to habitually ...
Bacterioplankton composition in tropical high-elevation lakes of the andean plateau
(2018)
High-elevation lakes in the tropics are subject to extreme environmental fluctuations and microbes may harbor a unique genomic repertoire, but their composition and diversity are largely unknown. Here, we compared the ...
