Systematically quantifying diversity across landscapes is necessary to understand how
clade history and ecological heterogeneity contribute to the origin, distribution, and …

The role of geography and ecology in speciation are often discussed in the context of
phylogenetic niche conservatism (PNC), the propensity of lineages to retain ancestral niche …

Aim Across angiosperm families, the area occupied by a family is strongly correlated with its
richness. We explore the causes of this area‐richness correlation using the cosmopolitan …

Ecological opportunity has been associated with increases in diversification rates across the
tree of life. Under an ecological diversification model, the emergence of novel environments …

• Premise of the study: Understanding heterogeneity in species richness across the tree of
life is a challenge in evolutionary biology. The sedge family, Cyperaceae, is classified into …

Biodiversity is often described as having multiple facets, including species richness,
functional diversity and phylogenetic diversity. In this paper, we argue that phylogenetic …

The sedge family (Cyperaceae: Poales; ca. 5600 spp.) is a hyperdiverse cosmopolitan
group with centres of species diversity in Africa, Australia, eastern Asia, North America, and …

Question Community phylogenetic approaches can provide information on the ecological
forces structuring plant community composition. For example, assuming evolutionary …

Background and aims–Cyperus is a large, ecologically diverse, and important sedge genus.
Recent systematic work resolved problems with generic delimitation and implicated C4 …

Tribe Rhynchosporeae (ca. 386 spp.; Cyperaceae) has high levels of endemicity (≥ 44%) in
tropical and subtropical American savannas and can provide insights into the diversification …
