The Neotropical region is the most diverse on the planet, largely owing to its mosaic of
tropical rainforests. Multiple tectonic and climatic processes have been hypothesized to …

The terrestrial biota of the Caribbean islands includes many lineages, some whose
presence on the islands dates back some 35–40 million years ago, when land bridges are …

Many orb-weaving spiders exhibit remarkable sexual dimorphism, hampering the matching
of males and females in taxonomic studies. This is the case for the spiny Micrathena spiders …

Abstract Aim Amazonia and Atlantic Rain Forests share a common biogeographical origin
and have an interconnected history that includes the drier biomes between them. It is not …

The recognition and delineation of cryptic species remains a perplexing problem in
systematics, evolution, and species delimitation. Once recognized as such, cryptic species …

Species delimitation is an imperative first step toward understanding Earth's biodiversity, yet
what constitutes a species and the relative importance of the various processes by which …

Aim Comparative phylogeography aims to unravel similarities in the population structure
and evolutionary processes undergone by co‐distributed taxa, under the assumption that …

Dispersal ability can affect levels of gene flow thereby shaping species distributions and
richness patterns. The intermediate dispersal model of biogeography (IDM) predicts that in …

The infraorder Araneomorphae comprises more than nine-tenths of spider diversity,
including most of the better known web-weaving spiders. As observed for other taxa, the …

The family Nemesiidae was once among the most species-rich of mygalomorph spider
families. However, over the past few decades both morphological and molecular studies …
