Conservation of species-rich subtropical grasslands: traditional management vs. legal conservation requirements in primary and secondary grasslands doi: 10.1590/0102-33062019abb0306 Table S1. Endemic and endangered species recorded in three grassland types (PGCA = primary grasslands in conservation areas, SGCA = secondary grassland in conservation areas, PGTM = primary grassland subjected to the traditionally management) at the fifty-eight study sites in southern Rio Grande do Sul, South Brazil. The degree of threat of species was checked in the current Red List made for the state (Decreto Estadual nº 52.109/ 2014) and endemic species is according to Andrade et al. 2018 – ED: Endemic; CR: Critically Endangered; EN: Endangered; VU: Vulnerable; NT: Near Threatened.

GLOBAL RELATIONSHIPS BETWEEN PLANT FUNCTIONAL TRAITS AND ENVIRONMENT IN GRASSLANDS EMMA JARDINE A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy The University of Sheffield Department of Animal and Plant Sciences Submission Date July 2017 ACKNOWLEDGMENTS First of all I am enormously thankful to Colin Osborne and Gavin Thomas for giving me the opportunity to undertake the research presented in this thesis. I really appreciate all their invaluable support, guidance and advice. They have helped me to grow in knowledge, skills and confidence and for this I am extremely grateful. I would like to thank the students and post docs in both the Osborne and Christin lab groups for their help, presentations and cake baking. In particular Marjorie Lundgren for teaching me to use the Licor, for insightful discussions and general support.

E-mail: [email protected] Abstract The Paititi Natural Reserve is located in the southeastern part of the Tandilia mountain range (Buenos Aires province, Argentina). With the aim of recording the floristic richness of Sierra Chica, an untouched area of the reserve, all vas- cular plants were inventoried and categorized by family, status, and life form. Altogether, 364 taxa from 72 families were found, with the most predominant families being Poaceae (20.7%), Asteraceae (20.1%), and Fabaceae (5.8%). We found 95 adventive species, 4 cosmopolitan, and 265 native. The most abundant life forms were hemicryptophytes (33.1%), therophytes (30.6%), and criptophytes (22.6%); the therophytes were mostly represented by adventive spe- cies. We also found species that were known from Buenos Aires province but not from mountainous areas. Despite being a small area within Argentina, Sierra Chica constitutes a valuable refuge for native flora of the Tandilia mountain range system, which is in danger of being affected by exotic plants. -
Quantifiable Differences Between Phytolith Assemblages Detected at Species Level: Analysis of the Leaves of Nine Poa Species (Poaceae)

However the understanding of grass phytolith variance and its implications to plant systematics is doubtless. In the present study phytoliths of the lateral shoots (leaves) of nine, globally distributed Poa species (Pooideae – Poaceae) are described. Phytoliths were recovered from Poa specimens by the dry ashing technique. Altogether 6223 disarticulated phytoliths were counted (approximately 500–700 phytoliths per species) in 54 plant samples, which cover six shoots of nine species. Not only the relative frequency of each morphotype was calculated, but measurements were conducted to determine the biogenic silica content of Poa lateral shoots. -

Cross-Scale Vegetation Patterns of Flooding Pampa Grasslands
JEC579.fm Page 562 Saturday, July 14, 2001 1:25 PM Journal of Blackwell Science, Ltd Ecology 2001 Cross-scale vegetation patterns of Flooding Pampa 89, 562–577 grasslands S. B. PERELMAN, R. J. C. LEÓN and M. OESTERHELD IFEVA – Departamento de Ecología, Facultad de Agronomía, Universidad de Buenos Aires, Av. San Martín 4453, 1417 Buenos Aires, Argentina Summary 1 The spatial pattern of vegetation heterogeneity across different scales may indicate the major environmental controls on vegetation structure, and thus guide strategies for the conservation of biodiversity. 2 We analysed cross-scale vegetation patterns in a 90 000-km2 area of natural grasslands in the Flooding Pampa, Argentina. We assessed the contribution of regional (latitudinal) and landscape (topographic) patterns of species turnover to overall heterogeneity using data from 749 censuses. 3 A large proportion of the variation in species composition across the entire region was observed at very fine spatial scales (0.1–10 km2), associated with subtle topographic features and soil salinity gradients. Latitudinal variation played a secondary role. 4 Species turnover among stands occupying different landscape positions at the same latitude was 50% greater than among inventories encompassing two degrees of latitude. The fine-grain heterogeneity determined that an area of 10 km2 was often sufficient to include 50% of all vascular plant species of the region. 5 Although a large proportion (nearly 70%) of the vascular flora was composed of rare (satellite) species that occurred in less than 10% of the samples, few core species (i.e. those occurring in more than 90% of the samples) were seen at any scale of analysis. -
