Coastal wetlands provide a range of important ecosystem services, yet they are under threat from a range of stressors including climate change. This is predominantly as a result of alterations to the hydroregime and associated edaphic factors. We used a three-year mesocosm experiment to assess changes in coastal plant community composition for three plant communities in response to altered water level and salinity scenarios. Species richness and abundance were calculated by year and abundance was plotted using rank abundance curves. The permutational multivariate analysis of variance with Bray–Curtis dissimilarity was used to examine differences among treatments in plant community composition. A Non-metric Multi-dimensional Scaling analysis (NMDS) was used to visualize the responses of communities to treatments by year. Results showed that all three plant communities responded differently to altered water levels and salinity. Species richness and abundance increased significantly in an Open Pioneer plant community while Lower and Upper Shore plant communities showed less change. Species abundances changed in all plant communities with shifts in species composition significantly influenced by temporal effects and treatment. The observed responses to experimentally altered conditions highlight the need for conservation of these important ecosystems in the face of predicted climate change, since these habitats are important for wading birds and livestock grazing.

“…The combined area of agriculture and planted pasture grew by 10.6%, from 44 million hectares to 48.6 million hectares, and the area planted with exotic trees increased from 600,000 hectares to 2.8 million hectares (363% increase) [53]. This conversion reduces the composition and richness of the fauna [54,55] and flora [56,57] communities of the soil, and can affect the ecosystem services offered by this biome.…”

Latin America and the Caribbean offer the most favorable natural and social conditions for the emergence of cattle ranching that regenerate and maintains the ecosystem services on which life on Earth depends, that is energy efficient and that contributes to meeting fundamental human food needs. Unlike other major global producers, cattle farming in Latin America and the Caribbean is fundamentally based on pasture. Therein lies both its strength (due to the regenerative potential of well-managed pastures) and its vulnerability (due to the pervasive link between deforestation and pasture formation, especially in the Amazon, where 40% of the Brazilian herd is concentrated). The diversification of pastures (today marked by impressive monotony, with brachiaria accounting for 85% of the species in Brazil), the introduction of legumes and tree plantations within them, and the proper management of herds, open the way to the possibility of drastically reducing the area currently occupied by the activity (especially in the Amazon) while maintaining the supply of its products. Agricultural research has disseminated forms of moderate intensification of cattle ranching, which represent a low opportunity cost of animal feed and, at the same time, regeneration of ecosystem services that have so far been destroyed by the prevailing methods of farming.

“…For subtropical grasslands in Brazil, studies that tested techniques of seed introduction still are scarce (e.g. Thomas et al 2019aThomas et al , 2019bPorto et al 2022) and few generalizations can be made about effectiveness of different seed introduction techniques. At the same time, seeds of native grassland species are not available on the market (Rolim et al 2022), making restoration projects challenging.…”

For subtropical Brazilian grasslands, few restoration techniques are established, and seeds of native grassland species are not available on the market. Here, we evaluated the effect of physical barriers (PB) on vegetation recovery in a degraded grassland. We considered species that exhibit attributes in their diaspores that facilitate dispersal as well-dispersed species (WDS) and compared the proportion of WDS at our site to their proportion in the regional species pool. To analyze plots near and distant from the PB, we calculated the extrapolated metrics by an asymptotic estimator (double sample size of each distance). We found 74 species in the degraded area, with higher richness and Shannon diversity values closer to logs, but higher Simpson values with larger distance from logs. Almost half of the species in the degraded area are WDS, more than in the regional species pool. While effects of logs on microsite conditions may also play a role (e.g. logs accumulating organic material or increasing soil moisture, providing shade), our data indicates that the PB works as a seed trap favoring the occurrence of WDS. It seems promising to develop applications in restoration, especially when associating PB with other restoration techniques to increase availability of adequate germination and establishment conditions.
