Summary: Mowing for hay is a significant land use in grasslands, and it is greatly affected by precipitation variability. The natural variation in precipitation can impact plant responses to changes in mowing intensity. Decreasing mowing intensity can increase plant productivity and forage yield in the whole community, but it may have negative effects on other plant species.

Summary: Enhanced drought, more frequent rainfall events and increased inter-annual variability of precipitation are expected for the Mediterranean. Through an experiment, we assessed the response of Mediterranean plant species to water deficit and found that different species have different abilities to cope with drought. Despite different responses, severe water deficit negatively affected plant biomass in all species studied. These findings provide important insights for predicting plant diversity and species composition in Mediterranean grasslands and Montado under climate change conditions.

Summary: Fire plays a crucial role in influencing the regeneration strategies of plants in Brazilian subtropical grasslands. Most species tend to resprout after treatments, with limited new establishments from seedlings. While there were no significant differences in the number of seedlings and resprouts between burned and mowed plots in each site, a higher number of species with seedlings was observed in sites with frequent burning, indicating the importance of fire in promoting plant diversity.

Summary: Understanding the impact of historical land uses and current management practices on biodiversity, particularly on ant communities in subtropical grasslands, is crucial. Secondary grasslands showed lower ant species diversity and distinct community composition compared to permanent grasslands, with the latter showing differences in composition based on management intensity. Passive recovery of grasslands may not fully restore ant communities, while traditional management practices enhance ant diversity.

Summary: Ephemeral streams in central Texas have been overlooked despite their common occurrence. This study examined the vegetation composition in an ephemeral dry stream channel and pools, revealing similarities in plant species between the two habitats. Panicum virgatum emerged as the dominant species, with a higher coverage than other plants. Perennial grasses and forbs were more abundant than annuals, and graminoids and forbs had greater coverage compared to trees, shrubs, vines, and ferns. Native species had greater coverage than non-native species. Droughts, flash floods, and scouring events were found to promote the dominance of perennial grasses and forbs in Leon Creek.

Summary: Foraging-tunnel disturbances created by plateau zokors have varying effects on above-ground biomass and species richness of graminoids and forbs in alpine grasslands. The disturbances decreased the species richness and biomass of forbs, while the response of graminoid species richness was different among the study sites. Reintroducing legumes may help mitigate the negative impact of foraging-tunnel disturbances on plant diversity and soil fertility.

Summary: The study investigated the bioindicators of aquatic environments using phytoplankton functional groups (FGs) in a subtropical estuarine river delta system. While water quality in 2015 was better than in 2012, there were no interannual differences in phytoplankton FGs similarities, suggesting that current water quality improvements were insufficient to affect the interannual alterations of FGs. Dominant FG diversity could be a good indicator of spatial and seasonal variations in water quality, showing lower diversity in high eutrophic conditions and higher diversity when water quality was better. Continuing efforts to improve water quality may enhance the diversity of dominant FGs in the study area.

Summary: Grasslands, covering nearly 40% of terrestrial biosphere, are home to vast biodiversity and provide livelihoods for over 1 billion people. Despite the rapid destruction and degradation of grasslands, recent research shows that complete recovery of biodiversity and essential functions takes a long time or may not occur at all. Grassland restoration has received less attention compared to restoration of forests, mainly because grasslands are considered to be able to reassemble quickly. Recognizing grassland restoration as a long-term process that aims to achieve old-growth endpoints, taking feedbacks and threshold shifts into account, is crucial in guiding the recovery of this globally important ecosystem.

Summary: The impacts of invasive alien species are influenced by their abundance and do not follow linear trends due to ecological interactions. Abundance-impact curves help inform management interventions by showing how per-capita impact changes as the invader becomes more abundant. This study found that increasing abundance of the invasive grass Urochloa decumbens had nonlinear effects on microhabitat properties, but linearly reduced temperature fluctuations. The invader had higher per-capita effects on native grasses at low abundance levels and on species richness at moderate invasion levels.

Summary: This research uses the CAETE model to examine the impact of plant trait diversity on vegetation carbon storage in the Amazon basin. The study found that including trait variability improves the model's representation of net primary productivity and vegetation carbon storage. Simulated reductions in precipitation resulted in a 60% loss of vegetation carbon storage across the basin. The trait-based approach allows for functional reorganization of the plant community in response to climate change.
