Terpenoid compositions and botanical origins of Late Cretaceous and Miocene amber from China.

PLoS ONE, 2014
The terpenoid compositions of the Late Cretaceous Xixia amber from Central China and the middle Miocene Zhangpu amber from Southeast China were analyzed by gas chromatography-mass spectrometry (GC-MS) to elucidate their botanical origins. The Xixia amber

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

Cladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

The Great Dividing Range as a driver of genetic divergence in a low‐dispersing dragonfly

Ecological Entomology, EarlyView.
Population genomic analyses revealed low genetic differentiation and no discrete population structure across the Great Dividing Range, indicating widespread gene flow in Synthemis eustalacta. Genetic divergence was associated with environmental gradients, elevation and landscape resistance rather than geographic distance, supporting isolation by ...

Arc polarity reversal in North Luzon preserved in the Oligocene–Miocene clastic units in southwestern Mountain Province, Philippines: insights from trace element geochemistry, microfossil ages, and zircon U–Pb dating

Geoscience Letters
Provenance studies using sedimentary geochemistry, particularly whole-rock, trace element, and rare earth element (REE) analyses, have proven useful in complex terranes such as the Philippines.
