“…A research with C. ciliaris demonstrated its ability to form dense populations and eliminate native species, in addition to establishing negative relationships with them. Its effects act over the structure, composition and diversity on the Caatinga herbaceous stratum (Alves et al 2017).…”

Biological invasions are increasingly common worldwide due to continuous transformations that environments have been undergoing. Thus, this study aimed to catalog the exotic invasive species that occur on different environments at the Agricultural Sciences Campus from the Federal University of the São Francisco Valley, Petrolina-PE and to measure the distribution of the species diversity in the evaluated environments. The study area was initially divided into six environments. By walking around (active search) through these environments, all exotic invasive species were collected and herborized. Overall, 29 species were sampled, distributed into 16 genera and 12 families. From all catalogued species, 18 were herbs, four trees, four climbing plants and three were bushes. Regarding their origin, 13 were from African continent, one from Europe, two from Asia, two from India, one from Madagascar and four from Central America. Some species still have natural occurrence at more than one continent. The ruderal environments showed greater similarity to each other, with a percentage of exotic invasive species in common, equal or greater than 75%. This study suggests that modified (degraded) environments are enabler of biological invasions.

Understanding the impacts caused by invasive plant species, especially in regions where studies are scarce, is of great importance to the development of management and conservation strategies. Amongst the biomes present in Brazil, the Caatinga (Dry Tropical Forest) stands out for having had few studies dealing with biological invasions by plants and animals. An evaluation of scientific production can provide a means by which the progress of invasion-related studies can be assessed, as well as identify research gaps and provide a broad overview of the importance of invasions in this biome. Thus, the objective of this study was to perform a scientometric analysis to evaluate the development of scientific research over the years on exotic and invasive plant species in the Caatinga. We found 46 papers dealing with invasive plants in the Caatinga published over a 14-year period. The main objectives of most of the papers focused on identifying the main strategies used by plants in the process of invasion and characterising the invaded environment. A total of 28 species were cited as invasive for the Caatinga, with Prosopis juliflora (Sw.) DC., Cryptostegia madagascariensis Bojer, Calotropis procera (Aiton) W.T.Aiton and Parkinsonia aculeata L. being the most cited species. Although studies on the subject are incipient, there is already important information about the dynamics of the invasiveness of plant species in the Caatinga, which can serve as a basis for new studies, as well as for the development of management policies, based on consistent information.
