“…Litter material with different composition may present a dissimilar decomposition rate (e.g., high lignin content is related to low decomposition rate) [10]. Some studies have reported faster litter decomposition in invaded environments when compared to the non-invaded environments [11,12]. However, litter deposition, litter quality, and litter decomposition from invaded environments in a tropical ecosystem are rare and poorly described.…”

Cryptostegia madagascariensis is an invasive plant species that covers 11% of the Brazilian northeastern territory, but its role on the litter trait in tropical ecosystems remains unclear. Here, we analyzed and compared the litter deposition, litter nutrient content, soil organic matter, and the litter decay rate from invaded and non-invaded environments by C. madagascariensis at a tropical Cambisol. The PCA analysis revealed that litter deposition, litter quality, and soil organic matter were correlated with the invaded environment. We grew plant species in greenhouse conditions to obtain a standard litter material to use in our litter bags in field conditions. We found that litter decay rate was higher in the invaded environment than in the non-invaded one. Our results suggest that C. madagascariensis changes litter traits in tropical ecosystems that in turn create negative plant–soil feedback to the native species by creating a physical barrier on soil surface and to promote its own rhizosphere.

“…In wetland ecosystems, hydrology is an important factor affecting the litter decomposition [20]. As one of the important characteristics of hydrology, water level could be increased by global warming and seasonal rainfall [21,22]. The increase of water level has been reported limiting the litter decomposition in the wetland ecosystems by altering the aeration condition and restricting the metabolism of microbes [16,23].…”

Wetlands are vulnerable to plant invasions and the decomposition of invasive plant litter could make impacts on the ecosystem services of wetlands including nutrient cycle and carbon sequestration. However, few studies have explored the effects of nutrient enrichment and water level change on the decomposition of invasive plant litter. In this study, we conducted a control experiment using the litterbag method to compare the decomposition rates and nutrient release in the litter of an invasive plant Alternanthera philoxeroides in three water levels and two nutrient enrichment treatments. This study found that the water level change and nutrient enrichment showed significant effects on the litter decomposition and nutrient dynamic of A. philoxeroides. The increase of water level significantly reduced the decomposition rate and nutrient release of litter in the nutrient control treatment, whereas no clear relationship was observed in the nutrient enrichment treatment, indicating that the effect of water level change on litter decomposition might be affected by nutrient enrichment. At the late stage of decomposition, the increase of phosphorus (P) concentration and the decrease of the ratio of carbon to P suggested that the decomposition of invasive plant litter was limited by P. Our results suggest that controlling P enrichment in water bodies is essential for the management of invasive plant and carbon sequestration of wetlands. In addition, the new index we proposed could provide a basis for quantifying the impact of invasive plant litter decomposition on carbon cycle in wetlands.

“…Plant tissues with high lignin content, and low C:N ratio, usually present low decomposition rate . Some studies showed that the litter decomposition and nutrient release into invaded soil occurs faster when compared to the non-invaded soils (Wang et al 2018, Chen et al 2019). However, the biomass production, litter decomposition, and litter quality of tropical invaded soils are rare and poorly described.…”

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.
