Isla de calor superficial urbano en los núcleos poblacionales de la provincia los ríos, ecuador y su influencia sobre la biodiversidad

The study conducted in Los Ríos province, Ecuador, assesses the impact of the urban surface heat island (USHI) phenomenon on local thermal conditions and biodiversity. To achieve this, urban, rural, and tree-covered areas were separated, where 12,152 sampling points were established, and land surface temperature data from the MODIS sensor were extracted. These data were averaged to identify variations in diurnal and nocturnal temperatures, thermal amplitude, and the magnitude of the urban surface heat island. It was found that urban development significantly contributes to increased surface temperatures, both during the day and night, compared to rural and vegetated areas. Vegetation plays a crucial role in thermal regulation, partially mitigating the urban heat island effect. The main findings show a positive correlation between surface temperature and urbanization level, highlighting the direct impact of urban density on local thermal conditions. Additionally, significant variables were identified, such as thermal amplitude, which indicates the difference between diurnal and nocturnal temperatures, and the USHI effect, which characterizes the intensity of the urban heat island phenomenon. Regarding biodiversity, greater species diversity was observed in urban areas compared to less urbanized rural areas. However, urbanization can also have long-term negative effects on biodiversity, including habitat loss and landscape fragmentation. Heat-sensitive species may be displaced or extinct in urban areas affected by the heat island, resulting in a decrease in biological diversity.
