Studies in evolutionary biology and biogeography increasingly rely on the estimation of
dated phylogenetic trees using molecular clocks. In turn, the calibration of such clocks is …

The Loxosceles genus spiders (the brown spiders) are encountered in all the continents,
and the clinical manifestations following spider bites include skin necrosis with gravitational …

The fish faunas of continental South and Central America constitute one of the greatest
concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living …

This review on all spider venom components known by the end of 2010 bases on 1618
records for venom compounds from 174 spider species (= 0.41% of all known species) …

Acoustic and substrate‐borne vibrations are among the most widely used signalling
modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs …

While previous research has indicated the utility of DNA barcoding in identifying spider
species sampled from a localized region, the effectiveness of this method over a broader …

Aim In this study we present a molecular phylogenetic and phylogeographical analysis of
Peltophryne (Anura: Bufonidae), an endemic genus of Antillean toads, to investigate the …

The venom enzyme sphingomyelinase D (SMase D) in the spider family Sicariidae (brown
or fiddleback spiders [Loxosceles] and six-eyed sand spiders [Sicarius]) causes …

Venomous animals use their venoms as tools for defense or predation. These venoms are
complex mixtures, mainly enriched of proteic toxins or peptides with several, and different …

Aim We present a molecular phylogenetic and biogeographical analysis of the
Mesoamerican cichlid fishes (Cichlidae: Cichlasomatinae: Heroini), a dominant part of the …
