The Caribbean islands harbor rich biodiversity with high levels of single island endemism.
Stretches of ocean between islands represent significant barriers to gene-flow. Yet some …

Island biogeographers have long sought to elucidate the mechanisms behind biodiversity
genesis. The Caribbean presents a unique stage on which to analyze the diversification …

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 …

Few spider species show truly cosmopolitan distributions. Among them is the banded
garden spider Argiope trifasciata, which is reported from six continents across major climatic …

The development of molecular techniques as a taxonomic tool and their integration with
information provided by other disciplines, has enhanced species discovery, facilitated …

The Andean uplift has played a major role in shaping the current Neotropical biodiversity.
However, in arthropods other than butterflies, little is known about how this geographic …

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 araneofauna of the extreme Southern Hemisphere is highly impoverished and
disharmonic. Four dead anthropogenic immigrant spiders have been collected from …

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 …

Several pieces of evidence support the hypothesis that the Amazon and Atlantic rainforests
were connected in the past, but the details of this historical disjunction are poorly …
