Influence of anthropogenic disturbances on stand structural complexity in Andean temperate forests: implications for managing key habitat for biodiversity
(2017)
Forest attributes and their abundances define the stand structural complexity available as habitat for faunal biodiversity; however, intensive anthropogenic disturbances have the potential to degrade and simplify forest ...
Characterization of fungal soil communities by F-RISA and arbuscular mycorrhizal fungi from Araucaria angustifolia forest soils after replanting and wildfire disturbances
(SPRINGER, 2009)
The Fungal Ribosomal Intergenic Spacer Analysis (F-RISA) was used to characterize soil fungal communities from three ecosystems of Araucaria angustifolia from Brazil: a native forest and two replanted forest ecosystems, ...
Habitat selection by the black-tufted marmoset Callithrix penicillata in human-disturbed landscapes
(Cambridge University Press, 2019)
Phytophagous insect fauna tracks host plant responses to exotic grass invasion
(SPRINGER, 2011)
The high dependence of herbivorous insects on their host plants implies that plant invaders can affect these insects directly, by not providing a suitable habitat, or indirectly, by altering host plant availability. In ...
Changes in escape behaviour of black iguanas (Ctenosaura similis) over an anthropogenic disturbance gradient
(2021)
Studies on the impact of human activity on animal behaviour are critical for understanding the extent to which humans affect ecological dynamics. Previous studies have found that human presence alters antipredator behaviours, ...
Effects of recreational activities on Patagonian rocky shores
(Elsevier, 2017-08)
Recreational activities can be an important source of anthropogenic disturbance in intertidal benthic assemblages. On rocky shores, activities such as trampling, snorkeling and the handling of organisms may have a negative ...
The case of the itata estuary (bio-bio region-chile) plant formations: anthropogenic interference or natural disturbance-induced diversity enrichment?
(2018)
The current study examined the relationship between native and introduced plant species, as indicators of the state of anthropogenic influence on plant formations in the area of the Itata estuary (Bio-Bio Region, Chile). ...
Hydrochemistry applied to assess the chemical weathering and soil removal rates in the Sorocaba River basin, Sao Paulo State
(Soc Brasileira Geologia, 2020-01-01)
Chemical weathering and soil removal rates are responsible for the Earth's landscape, composition of surface and ground-water, producing the soils and buffering the composition of the atmosphere. This study aimed to assess ...
