Day and night surface and atmospheric heat islands in a continental and temperate tropical environment
Urban areas cause several transformations in the landscape through the replacement of vegetation and permeable soils for buildings and waterproofing of surfaces. Such changes result in a different energy balance according ...
Daily evolution of urban heat islands in a Brazilian tropical continental climate during dry and rainy periods
High temperatures are typically recorded in tropical continental climate regions, with heat intensified by urban heat islands. This research attempts to investigate the intensity and maintenance of heat islands in the lower ...
Spatial variability and intensity frequency of surface heat island in a Brazilian city with continental tropical climate through remote sensing
Tropical cities located in inland Brazil typically have high temperatures that are extremely uncomfortable and detrimental to their population's health. This article analyzes the spatial variability of target temperatures, ...
SURFACE HEAT ISLANDS: FREQUENCY OF SPATIAL INTENSITY AND VARIABILITY IN A CITY WITH A CONTINENTAL TROPICAL CLIMATE
(Univ Estado Rio Janeiro, 2019-01-01)
The purpose of this article was to analyze the spatial distribution of target temperatures and the frequency of surface heat island intensities in areas with characteristics relating to land use, vegetation cover, densities ...
Spatial modeling of an urban Brazilian heat island in a tropical continental climate
Because climate aspects should be an important consideration when structuring urban spaces, this paper reports the results of combined field measurements and surface sensing data analyzed using statistical calculations. ...
Controls on the T phase energy fluxes recorded on Juan Fernandez Island by continental seismic wave paths and Nazca bathymetry
(Amer Geophysical Union, 2018)
T phases from 54 South American earthquakes with M-w > 5.2 are observed at a broadband station on Juan Fernandez Island. We computed the T phase energy flux (TPEF) values of the seismograms. The TPEF values show a large ...
Molecular phylogeny of the South American sheldgeese with implications for conservation of Falkland Islands (Malvinas) and continental populations of the Ruddy-headed Goose Chloephaga rubidiceps and Upland Goose C. picta
(Cambridge University Press, 2014-03)
Sheldgeese of the genus Chloephaga are waterfowl (Anatidae) endemic to mainland South America and the Falkland Islands (Malvinas). Continental populations of three species C. picta, C. poliocephala, and C. rubidiceps breed ...
The life and adventures of an eight-legged castaway: Colonization and diversification of Philisca ghost spiders on Robinson Crusoe Island (Araneae, Anyphaenidae)
(Academic Press Inc Elsevier Science, 2017-02)
Oceanic archipelagoes, by their young origin and isolation, provide privileged settings to study the origin and diversification of species. Here, we study the anyphaenid spider genus Philisca, endemic to the Valdivian ...
Genetic variation (AFLPS and nuclear microsatellites) in two anagenetically derived endemic species of Myrceugenia (MYRTACEAE) on the Juan Fernandez Islands, Chile
(BOTANICAL SOC AMER INC, PO BOX 299, ST LOUIS, MO 63166-0299 USA, 2013)
Urban heat islands in small and medium-sized cities in Brazil and the context of climate change
(Revues Org, 2020-01-01)
Since the constitution of the planet, the climate has been both warmer and colder, and both drier and more humid than current conditions. Nevertheless, we are facing strong changes in the natural landscape resulting from ...
