Neotropical freshwater fishes (NFFs) constitute the most diverse continental vertebrate fauna
on Earth, with more than 6,200 named species compressed into an aquatic footprint< 0.5 …

Bryophytes include about 20,000 species characterized by their poikilohydric condition, high
long-distance dispersal capacities, and cold tolerance. Despite these specific life-history …

After decades of debate, biologists today largely agree that most speciation events require
an allopatric phase (that is, geographic separation), but the role of adaptive ecological …

Aim Our objective is to analyse global‐scale patterns of mountain biodiversity and the
driving forces leading to the observed patterns. More specifically, we test the 'mountain …

The origin of phenotypic diversity among higher clades is one of the most fundamental
topics in evolutionary biology. However, due to methodological challenges, few studies have …

Evolutionary radiation is a widely recognized mode of species diversification, but its
underlying mechanisms have not been unambiguously resolved for species-rich …

Environmental change can create opportunities for increased rates of lineage diversification,
but continued species accumulation has been hypothesized to lead to slowdowns via …

Mountain systems harbor a substantial fraction of global biodiversity and, thus, provide
excellent opportunities to study rapid diversification and to understand the historical …

The megadiverse genus Carex (c. 2000 species, Cyperaceae) has a nearly cosmopolitan
distribution, displaying an inverted latitudinal richness gradient with higher species diversity …

Growing evidence for lineage diversification that occurs without strong ecological
divergence (ie, nonadaptive radiation) challenges assumptions about the buildup and …
