Abstract Conspicuous centers of biodiversity are frequently attributed to local conditions that promote speciation or resistance extinction, but recent diversification studies indicate this mode explanation might not be very general, so it may fruitful revisit the role dispersal in concentrating biodiversity. Here we consider processes underlying marine diversity hotspot Indo-West Pacific among...

Introduction Conclusions References

A phylogenetic tree for acrodont lizards (Chamaeleonidae and Agamidae) is established based on 1434 bases (1041 informative) of aligned DNA positions from a 1685-1778 base pair region of the mitochondrial genome. Sequences from three protein-coding genes (ND1, ND2, and COI) are combined with sequences from eight intervening tRNA genes for samples of 70 acrodont taxa and two outgroups. Parsimony...

The citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), is a world-wide pest of citrus (Heppner 1993) described originally in India (Stainton 1856). In the USA, it was initially found in Homestead, Florida and parts of Dade, Broward and Collier counties in 1993 (Heppner 1993). Its distribution is now widespread across Florida in citrus-growing regions, and is spread...

The evolution of Tethyan phosphogenesis during the Cretaceous–Eocene is examined to try to explain fluctuations of phosphogenesis through time, and whether or not they reflect long-term changes in ocean circulation or in continental weathering. Twenty-seven time-stratigraphic phosphate levels in various Tethyan sites, covering a time span of about 90 Myr from the Hauterivian to the Eocene, were...

Global warming is widely regarded to have played a contributing role in numerous past biotic crises. Here, we show that the end-Permian mass extinction coincided with a rapid temperature rise to exceptionally high values in the Early Triassic that were inimical to life in equatorial latitudes and suppressed ecosystem recovery. This was manifested in the loss of calcareous algae, the near-absenc...

Based on specimens originally referred to as "Dastilbe minor", a nomem-nudum, we describe a new genus of Chanidae †Nanaichthys longipinnus nov. gen. and sp. which exhibits several diagnostic characters such as the absence of orbitosphenoid and basisphenoid, anteriorly displaced quadrate-mandibular articulation, laterally expanded supraneurals, an acute angle between the preopercular limbs, expa...
