“…These studies are directly related to the propagation pressure hypothesis, according to which some exotic herbaceous and tree species produce a high number of seeds to occupy an invaded area (Lockwood et al 2009). Other analysed papers sought to explain the process of invasion by the species C. procera (Fabricante et al 2013), C. madagascariensis (Araújo et al 2017;Silva et al 2017b), Nicotiana glauca Graham (Fabricante et al 2015b), A. indica and P. juliflora (Silva et al 2018) by the production of allelopathic substances. These authors verified that substances present in the leaves of these invaders impede seedling germination and development of native species mainly in anthropised areas.…”

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.

“…A maioria dos estudos realizados na região são com C. madagascariensis, relacionados à fitossociologia (Rebouças Filho et al, 2021) alelopatia (Araújo et al, 2017), germinação de sementes (Silva et al, 2017), solos (Medeiros et al, 2019), dentre outros, porém de acordo com registros de herbários, há também a ocorrência de C. grandiflora, e até então não há estudos voltados para a distribuição e intensidade de invasão dessa espécie nessa região. Assim, é preciso saber de fato quais espécies tem maior distribuição, assim como qual a intensidade de invasão por essas espécies para que se possa articular ações de manejo e conservação da biodiversidade visando mitigar os danos ambientais causados por essas invasoras.…”

Os impactos causados por espécies invasoras do gênero Cryptostegia, conhecida como rubber vine, no mundo já é bastante conhecido. No Brasil, o principal alvo dessas espécies é a Copernicia prunifera (Mill.) H.E.Moore, uma palmeira com grande valor econômico e ecológico para toda a região Nordeste do Brasil. Nesse contexto, o objetivo de trabalho foi investigar como as populações de espécies do gênero Cryptostegia afetam os bosques de C. prunifera em diferentes ecossistemas do Bioma Caatinga de quatro estados na região Nordeste do Brasil. Para tanto, foram percorridos cerca de 25.000 km durante 15 expedições de campo de oito dias de duração e coletados material botânico de indivíduos dessa planta invasora para a posterior identificação em laboratório. Também foram coletadas amostras de solo. Os resultados indicam que nos quatro estados visitados há grandes áreas infestadas por essa invasora, e que há ocorrência confirmada de Cryptostegia madagascariensis Bojer e Cryptostegia grandiflora R.Br., e ainda a presença de uma espécie híbrida. A partir dos resultados desse estudo, pode-se concluir que espécies do gênero Cryptostegia possuem uma grande distribuição em vários ecossistemas locais e está causando sérios impactos negativos a biodiversidade nativa e a economia da região Nordeste do Brasil. Os bosques de C. prunifera são os mais afetados por essa bioinvasão, causando a morte de milhares de indivíduos dessa palmeira.Palavras-chave: Caatinga, bioinvasão, distribuição, impactos, rubber vine, Mata Ciliar. Distribution and Invasion Intensity of Cryptostegia spp. in Four States in Northeast BrazilA B S T R A C TThe impacts caused by invasive species of the genus Cryptostegia, known as rubber vine, are well registered worldwide. In Brazil, the main target of these species is Copernicia prunifera (Mill.) H.E.Moore, a palm tree with great economic and ecological value for the entire northeast region of Brazil. In this context, the objective of this work is to investigate how populations of Cryptostegia species affect C. prunifera forests in different ecosystems of the Caatinga biome in four states of northeastern Brazil. About 25,000 km were traveled during 15 eight-day field expeditions and botanical material was collected from individuals of invasive plants for later identification in the laboratory. Soil samples were also collected. The results indicated the existence of large areas infested by the invasive plants in the four states visited, and the occurrence of Cryptostegia madagascariensis Bojer and Cryptostegia grandiflora R.Br., as well as a hybrid species, was confirmed. The results of this study lead to the conclusion that species of the genus Cryptostegia are largely distributed in several local ecosystems and are responsible for serious negative impacts on native biodiversity and on the economy of the northeast region of Brazil. C. prunifera forests are the most affected by this bioinvasion, where the invasive plants cause the death of thousands of individuals of this palm.Keywords: Caatinga, bioinvasion, distribution, impacts, rubber vine, Riparian Forest.
