“…The exotic plant species once spreading into a new range that is characterized by low fertility and resources availability creates some strategies, such as: i) enhancing soil fertility by high quality litter deposition (e.g., N, P, and K contents); and ii) Promoting soil organic matter content, thus modifying the rhizosphere (e.g., island of fertility hypotheses) (Patil et al 2020, Shiferaw et al 2021. In tropical ecosystems with long dry season (e.g., more than 4 months) the native plant species usually present high water use e ciency (e.g., lower water loss by evapotranspiration), and reduces its metabolism during the dry season by: i) reducing the aboveground biomass allocation (e.g., producing thinner leaves and lower growth rates); ii) high wood and vessel density; iii) little seasonal variation in litter deposition (Kupers 2019, de Oliveira et al 2020). So, our results showed a clear dissimilarity among both ecosystems (invaded vs. native).…”

The invasive Cryptostegia madagascariensis occupies riparian areas covered by tropical Cambisols throughout the North-eastern Brazil however litter is known regarding its ability to impact litter inputs, and ecosystem processes. This study aimed to characterize the effects of the invader on the litter deposition, soil physical-chemical properties, litter nutrient content, and the litter decay rate in a Tropical Cambisol. Comparisons of native and invaded environments showed that C. madagascariensis alters the quantity of litter deposition during both dry and rainy seasons. In contrast to native species, C. madagascariensis litterfall displayed litter seasonal variation (rainy vs. dry season), however invaded sites had higher litter biomass compared to native sites. C. madagascariensis litter was enriched in soil organic matter, N, P, and K contents as compared to the native litter. Compared to native environments, invaded ones had significantly decreased soil temperature and soil water content. Results suggest that C. madagascariensis enhances litter and N, P, and K availability in ways that have potential to impact soil ecosystem in the Tropical Cambisols from Caatinga ecoregion, Brazil.

“…Relationships between chemical and morphological traits across a range of plant species have been rarely investigated (but see, e.g., [20,23,24]). Disentangling these relationships may improve our understanding of how plants adapt to the various challenges of climate change [25].…”

Plants show an extraordinary diversity in chemical composition and are characterized by different functional traits. However, relationships between the foliar primary and specialized metabolism in terms of metabolite numbers and composition as well as links with the leaf economics spectrum have rarely been explored. We investigated these relationships in leaves of 20 woody species from the Mediterranean region grown as saplings in a common garden, using a comparative ecometabolomics approach that included (semi-)polar primary and specialized metabolites. Our analyses revealed significant positive correlations between both the numbers and relative composition of primary and specialized metabolites. The leaf metabolomes were highly species-specific but in addition showed some phylogenetic imprints. Moreover, metabolomes of deciduous species were distinct from those of evergreens. Significant relationships were found between the primary metabolome and nitrogen content and carbon/nitrogen ratio, important traits of the leaf economics spectrum, ranging from acquisitive (mostly deciduous) to conservative (evergreen) leaves. A comprehensive understanding of various leaf traits and their coordination in different plant species may facilitate our understanding of plant functioning in ecosystems. Chemodiversity is thereby an important component of biodiversity.

“…Portanto, em se tratando de estratégias de conservação, os estudos sobre a composição florística e a estrutura fitossociológica em formações vegetais são de fundamental importância em todas as regiões, uma vez que contribuem para o conhecimento e a compreensão da estrutura e da dinâmica da vegetação, o que possibilita reunir informações quantitativas sobre as áreas pesquisadas, em especial sobre a abundância e a distribuição geográfica das espécies, e suas relações com os fatores ambientais, climáticos, pedológicos e ecológicos em diferentes locais e escalas (Marangon et al, 2016;Sabino et al, 2017;Souza et al, 2017;Vasconcelos et al, 2017;Gomes et al, 2020;Oliveira et al, 2020;Silva et al, 2020;Sousa et al, 2021).…”

“…Em se tratando do bioma Caatinga, nas últimas décadas importantes estudos de florística e fitossociologia foram realizados, e outros têm sido propostos em várias regiões do Nordeste (Marangon et al, 2016;Oliveira et al, 2020;Silva et al, 2020). Em suma, estes estudos de diversidade e da estrutura de plantas da Caatinga permitem monitorar algumas espécies nativas chaves dentro dos ecossistemas e\ou das eventuais alterações na estrutura da vegetação e seus processos dinâmicos complexos, e podem, ainda, fornecer subsídios que possibilitem compreender melhor sobre este bioma, auxiliando em pesquisas biogeográficas, ecológicas, taxonômicas, evolutivas e de conservação (Pereira-Júnior et al, 2012;Capon, 2019;Fernandes et al, 2019;Oliveira et al, 2020;Nóbrega et al, 2020). Para o Estado do Piauí, a literatura científica sobre levantamento florístico e fitossociológico se encontra em ascensão, sendo mais representativa nos Cerrados, em áreas de Ecótonos, Carrasco e nas Restingas piauienses, respectivamente, com diferentes abordagens e análises, sendo a Caatinga a menos estudada (Silva et al, 2018;Sousa e Santos-Filho, 2018;Oliveira et al, 2019aOliveira et al, , 2019bLima et al, 2020;Castro, 2020;Silva et al, 2020).…”

The The Poti River Canyon State Park (24,772.23 ha), located in the municipality of Buriti dos Montes, is an important Conservation and Environmental Protection Unity in the State of Piauí. Therefore, this research purpose was to identify the angiosperms species which occurr in rocky outcrops in the aforementioned Park. The collection, herborization, identification and classification of specimens was followed the usual specialized literature. The specimens are deposited in the Herbarium Prof. Aylthon Brandão Joly, located on the Center for Superior Studies of Caxias, CESC / UEMA. The park's angiosperm flora is composed by the 96 species, distributed in 82 genera and 34 families. Among these, 85.4% (82 spp.) are eudicotiledonous and 14.6% (14 spp.) are monocotyledonous. The richest families in number of species were Fabaceae (21 spp.), Apocynaceae and Cactaceae (6 spp.); Bignoniaceae and Euphorbiaceae (5spp); Araceae, Anarcadiaceae, Boraginaceae, Cyperaceae and Malvaceae (4 spp.); Bromeliaceae and Rubiaceae (3 spp.), which together had a total of 71.9% of the species, while the others presented between one and two species (28.1%). For this study area, 8.3% (8 spp.) was the firts records for Piauí state, they are Astrocaryum vulgare Mart., Cyperus pohlii (Ness) Steud., Cryptostegia madagascariensis Bojer, Cordia oncocalyx Allemão, Ibatia ganglinosa (Vell.) Morillo, Piptadenia retusa P.G.Ribeiro, Seigler & Ebinger, Vitex gardneriana Schaue e Waltheria operculata Rose as its representants. 14,6% (14 spp.) are endemic to the Caatinga and 5,2% (5 spp.) are new species records for it. This is the first floristic study for the municipality, which contributes with important information to the area of rocky outcrops, increasing the occurrence and the geographic distribution of the species in Brazil.
