New Geochronological Constraints on the Late Palaeozoic Tarija Basin, Southern Bolivia: Tectonic and Palaeoclimatic Implications

Terra Nova, EarlyView.
ABSTRACT The Carboniferous‐Permian Tarija basin of southern Bolivia evolved under major tectonic and climatic influence. The timing of transition from glacially influenced to arid conditions, after the Gondwanide tectonic event, has been based mainly on palynological correlations.

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)

Terra Nova, EarlyView.
ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,

Inverse Latitudinal Diversity Gradient, Systematics and Historical Biogeography in the Gomphocerinae Grasshoppers (Orthoptera, Acrididae)

Zoologica Scripta, EarlyView.
ABSTRACT The latitudinal diversity gradient (LDG), that is, the increase in species richness from the poles to the equator, is one of the oldest known ecological patterns. Its inverse (iLDG), where species richness increases toward higher latitudes, is less common but has recently attracted growing scientific interest.

Out‐of‐Africa: Origin of the Disjunct Distribution of Paleotropical Eneopterinae Crickets (Gryllidae, Xenogryllini)

Zoologica Scripta, EarlyView.
ABSTRACT Many groups of terrestrial plants and animals display a disjunct distribution pattern in the Paleotropics, being found almost exclusively in tropical Africa and Asia. The origin of such a pattern may be manifold, particularly for older lineages where plate tectonics potentially played an important role.
