Land degradation is a complex concept that integrates different aspects, including changes in soil conditions, biodiversity, productivity and socio-economic implications, compared to reference state. We propose new conceptual framework analyze stages restoration thresholds species-rich natural grasslands. The with their respective describes key processes of land-use change lead certain thresholds. Specifically, we discuss two scenarios grassland degradation, i.e. unsuitable management...
Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, neglected terms of conservation, and knowledge its fragmented. We aim to answer the question: how many, which, species occur Pampa? In a collaborative effort, we built lists plants, animals, bacteria, fungi that Pampa. included information distribution patterns, main habitat types, status. Our study resulted referenced totaling 12,503 (12,854 taxa, when...
Abstract Aims We offer a first classification of South Brazilian grasslands ( Campos Sulinos ) based on quantitative vegetation data and describing grassland types in terms dominant indicator species. Location (Paraná, Santa Catarina, Rio Grande do Sul states). Methods described plots 167 sampling units throughout the region using stratified nested design, totalizing 1,502 1 m² quadrats. classified cluster analysis Bray–Curtis dissimilarities, establishing three ten subtypes. conducted...
Grazing exclusion may lead to biodiversity loss and homogenization of naturally heterogeneous species-rich grassland ecosystems, these effects cascade higher trophic levels ecosystem properties. Although grazing has been studied elsewhere, the consequences alleviating disturbance regime in ecosystems remain unclear. In this paper, we present results first five years an experiment native grasslands southern Brazil. Using a randomized block experimental design, examined three treatments on...
Effective scientific efforts and conservation actions transcend political boundaries, encompassing entire ecological units. We compiled a vascular plant species list for the Río de la Plata grassland ecoregion, one of largest continuous ecosystems, in Americas. Our is based on existing regional lists, online databases published literature, taxonomically verified complemented by additional information distribution three countries (Argentina, Brazil Uruguay) origin species. 4864 accepted names...
In times of unprecedented climate change, ecological restoration efforts have a strong focus on forests for the purpose carbon sequestration. Grasslands, in contrast, remain relatively neglected global policies. Concurrently, we are midst biodiversity crisis—it is estimated that 1 million species globally threatened with extinction. Here, present analyses from central Europe and southern Brazil show majority our endangered plant fact found open ecosystems. Using Germany as an example, could...
Abstract Habitat loss is one of the greatest threats to biodiversity, exerting negative effects on ecological viability natural vegetation remnants. The south Brazilian grasslands belong largest temperate grassland regions in world, but have lost 50% their extent past 35 years. To date, there no empirical evidence for habitat these grasslands' biological diversity, undermining conservation. Using data from a large‐scale biodiversity survey, we asked if local plant communities respond levels...
The natural vegetation in the highlands of southernmost state Brazil, Rio Grande do Sul, is characterized by extensive grasslands mosaics with Araucaria forests, usually under cattle grazing. Plant species diversity and endemism these high, though poorly recognized conservation policy general public, conversion rates into other land uses are high. In this paper, we give an overview principal biological features grassland South Brazilian highland region (plant richness diversity) initiate a...
Abstract With the aim to identify future challenges and opportunities in vegetation science, we brought together a group of 22 early career scientists from diverse backgrounds perform horizon scan. In this contribution, present selection 15 topics that were ranked by participants as most emergent impactful for science face global change. We highlight methodological tools expect will play critical role resolving emerging issues providing ways unveil new aspects plant community dynamics...
Cortaderia selloana (Schult. & Schult. f.) Asch. Graebn. (Pampas grass) is a perennial grass native to temperate and subtropical regions of South America. The species was introduced western Europe for ornamental purposes during the nineteenth century, where it has become naturalized in anthropogenic natural habitats, especially sandy, open, disturbed areas. Female plants C. produce thousands seeds that are dispersed over long distances by wind germinate readily. Its invasive success also...
Our editorial introduces a Special Collection of scientific articles on current vegetation research in the most biodiverse all biogeographic realms, Neotropics. It contains nine contributions dedicated to data, description and classification. Four papers provide new classifications important Neotropical biomes, namely Arid Chaco Argentina, Mexican temperate forests, Andean wetlands Argentine Puna southern Peru. Furthermore, one study provides novel bioclimatic-vegetation classification...
Management-intensive grazing, which is proposed to increase forage and animal productivity maintain soil integrity biodiversity, seen as an alternative meet 21st century agricultural environmental challenges. The purpose of this study was test the hypothesis that high levels trampling standing vegetation associated with mob grazing (a.k.a., ultrahigh stocking density) leads increased plant diversity productivity. A long-term experiment established on a subirrigated meadow in Nebraska...
Abstract Questions What are the drivers that govern fern and lycophyte community composition across different elevation zones in South Brazilian Atlantic Forest? Does explanatory power of models increase when we consider substrate‐based life forms separately? Do terrestrial epiphytic species respond similarly to environmental drivers? Study site Four distinct Rain Forest sensu stricto northeastern Rio Grande do Sul, Brazil. Method Variation partitioning was used investigate role climatic,...
Grassland and savanna ecosystems are the original vegetation types of more than 30% Brazilian territory, but conservation training future professionals has largely focused on forests. In fact, no standard protocols exist for sampling grassland environmental planning or licensing. Neglecting non-forest may have deleterious consequences maintenance biodiversity provisioning ecosystem services. Herein, we provide practical guidelines how to conceive develop ecological studies scientific,...

Aquatic ecosystems support species diversity, and knowledge of plant communities is essential for wetland conservation programs. This study provides a checklist aquatic vascular plants South Brazil establishes their floristic affinities with bordering America phytogeographical domains. The was based on 52 sources, including 35 lists, 17 regional taxonomic studies, information from an electronic database wetlands Brazil. Floristic similarities published checklists neighbouring regions were...
Abstract Aims To identify environmental and anthropogenic drivers of alpha‐ beta‐diversity for native alien plant species. Location Río de la Plata grasslands, South America (Argentina, Brazil Uruguay; 27.3–39.1°S, 50.1–66.5°W). Methods We assembled a data set 597 vegetation plots distributed across the grasslands. assess alpha‐diversity (species richness), we performed generalized least‐squares regression using predictors. evaluated differences in Simpson's pairwise dissimilarity between...
Solanaceae comprises many species complexes, taxonomically challenging lineages that require specialized effort to be reliably delimited, and thus develop a reasoned hypothesis at the level. To obtain an overview of aspects permeate complexes studies in Solanaceae, we collected summarized details selected works, resulting 83 published articles comprising nine genera. Solanum, most studied genus, spans all explored biogeographic realms, characterized by taxonomic complexity related its long...
