Abstract
Restinga forests and open scrubby formations establish on sandy well-drained soils alongside the Brazilian coastline. Restinga plants are exposed to extreme conditions and vegetation types are mainly structured by species access to groundwater. But to date, no systematic evaluations have been done in order to characterize soil microclimatic conditions and understand how they are associated with variations in climatic drivers. We evaluated hourly soil moisture and temperature along 84 days at Restinga Seasonal Dry Forest (SDF), sparse (Open Clusia Scrubs—OCS), and dense (Open Ericacea Scrubs—OES) tickets at Restinga de Jurubatiba National Park, at Rio de Janeiro state (Brazil). Due to distinctions on physical structure and access to groundwater between plant formations, we expected higher daily soil moisture and lower daily moisture and temperature variations on forests than on open vegetated areas. Daily soil moisture was higher, respectively, on SDF, OES, and OCS, whereas soil moisture and temperature variability presented the opposite trend (SDF < OES < OCS), supporting our hypotheses. Daily soil temperature dynamics are quite well predicted by solar radiation incidence patterns, whereas daily soil moisture is mainly regulated by precipitation at OCS, an interaction of precipitation and temperature at OES and delayed effects of precipitation at SDF. Our results corroborate our expectations that forests are more effective in buffering both air temperature and precipitation effects on soil conditions than open vegetated areas. They also indicate that soil moisture and temperature conditions are important aspects differentiating Restinga vegetation types.
期刊介绍:
Air, Soil & Water Research is an open access, peer reviewed international journal covering all areas of research into soil, air and water. The journal looks at each aspect individually, as well as how they interact, with each other and different components of the environment. This includes properties (including physical, chemical, biochemical and biological), analysis, microbiology, chemicals and pollution, consequences for plants and crops, soil hydrology, changes and consequences of change, social issues, and more. The journal welcomes readerships from all fields, but hopes to be particularly profitable to analytical and water chemists and geologists as well as chemical, environmental, petrochemical, water treatment, geophysics and geological engineers. The journal has a multi-disciplinary approach and includes research, results, theory, models, analysis, applications and reviews. Work in lab or field is applicable. Of particular interest are manuscripts relating to environmental concerns. Other possible topics include, but are not limited to: Properties and analysis covering all areas of research into soil, air and water individually as well as how they interact with each other and different components of the environment Soil hydrology and microbiology Changes and consequences of environmental change, chemicals and pollution.
