Species environmental niches are central to ecology, evolution, and global change
research, but their characterization and interpretation depend on the spatial scale …

Tree ferns are a ubiquitous and often locally dominant element of wet southern temperate
rainforests across Australasia, southern Africa and in regions adjacent to the tropics in South …

Background Lejeunea is a largely epiphytic, subcosmopolitan liverwort genus with a
complex taxonomic history. Species circumscriptions and their relationships are subject to …

Evolutionary and biogeographic processes determine species richness patterns of vascular
plants between Eastern Asia (EA) and Eastern North America (ENA). However, the strikingly …

Knowing how species and communities respond to environmental change is fundamental in
the context of climate change. The search for patterns of abundance and phenotypic …

Abstract Background and Aims The tremendously unbalanced distribution of species
richness across clades in the tree of life is often interpreted as the result of variation in the …

Adaptive divergence in coloration is expected to produce reproductive isolation in species
that use colourful signals in mate choice and species recognition. Indeed, many adaptive …

Ferns and lycophytes are excellent model organisms to investigate the effect of climate
change on species niches, due to their high sensitivity to changes in temperature and …

The scaly tree ferns, Cyatheaceae, form a large natural group of ca. 640 species. They
comprise an ideal model for studying the biogeography of plants due to their broad …

Variation in species richness across regions and between different groups of organisms is a
major feature of evolution. Several factors have been proposed to explain these differences …
