Bridging micro and macroevolution: insights from chromosomal dynamics in plants. [PDF]
Understanding the relationship between macro- and microevolutionary processes and their delimitation remains a challenge. This review focuses on the role of chromosomal rearrangements in plant population differentiation and lineage diversification ...

The latitudinal variation in amphibian speciation rates revisited. [PDF]
Speciation can increase regional species richness, however, our knowledge of how and why speciation rates vary across space is still incomplete. Using comprehensive information on species distributions and their phylogenetic relationships, we describe ...

Anthropogenic emissions of mercury to the environment are of great concern due to its toxicity. The burning of coal contributes highly to Hg emissions and, as such, much lower effluent discharge limits for Hg in flue gas desulphurisation (FGD) wastewater

Direct Calibration Method for LA-HR-ICP-MS Apatite U-Pb Dating
BACKGROUND Apatite is a common U-bearing accessory mineral with a U-Pb closure temperature of ~500℃, making U-Pb dating of apatite a potentially valuable thermochronometer.

Metal Flux from Dissolution of Iron Oxide Grain Coatings in Sandstones
Iron oxide grain coatings in red sandstones contain trace metals that are released upon dissolution of the coatings. Analyses by ICP-MS following acid leaching of the grain coatings show that the dissolved metals can constitute an ore-forming fluid, as ...

Allopatric speciation is more prevalent than parapatric ecological divergence in a recent high-Andean diversification (Linochilus: Asteraceae) [PDF]
Elucidating how species accumulate in diversity hotspots is an ongoing debate in evolutionary biology. The páramo, in the Northern Andes, has remarkably high indices of plant diversity, endemicity, and diversification rates.
