RESUMO:

The process of biological invasion is considered one of the greatest threats to global biodiversity, impacting sociocultural, economic, and human health aspects. The Caatinga, a Brazilian biome recognized as the largest and most continuous area of Seasonally Dry Tropical Forests and Scrublands (SDTFs) in the New World, exhibits high floristic biodiversity that is increasingly threatened by invasive alien plants. Cryptostegia madagascariensis Bojer (Apocynaceae) is a climbing shrub species native to Madagascar, Africa, that poses severe challenges to native biodiversity, soil biota, litter deposition, and the seed bank, particularly in riparian forests of the Caatinga. Research on invasive alien plants in the Caatinga is still in its infancy, with a lack of studies addressing the impacts and control of biological invasions in the Potiguar region of the biome. In this context, the present study aims to investigate the biological invasion of C. madagascariensis in riparian forests of the Potiguar Caatinga, focusing on three investigative aspects: occupation, flora structure and environmental impact, and potential biological control. Specific methodologies were developed for each element, detailed in this dissertation's chapters. In summary, it was found that in the Potiguar Caatinga, the occupation of C. madagascariensis aligns with optimal environments for invasion, primarily located in the Western Potiguar mesoregion. The invasion and establishment of large monospecific stands of this species negatively impact the native phytodiversity of riparian forest sites. Populations of Ceraia sp., a native katydid species from South America, may serve as a potential biological control agent against the invasion of C. madagascariensis in the Caatinga. The findings presented are expected to support policies for controlling and eradicating invasive alien species and foster future scientific research on biological invasion ecology in the Caatinga biome.
