Age‐related trends in niche position and specialization in Neotropical vertebrates

Ecography, EarlyView.
Species' niche positions and breadths within a region's environmental space, measured through ecological niche factor analysis (ENFA) as marginality and specialization, can reflect evolutionary constraints related to lineage age. The ‘internal incumbency' hypothesis predicts that older species, due to competitive preemption, occupy more central niche ...

Quaternary deposition and erosion in the northeastern Sunda Strait: An interplay between sea level, tectonics, and magmatic activity

Journal of Asian Earth Sciences: X
The northeastern Sunda Strait is a narrow strait separating Java and Sumatra islands. Currently, it forms a seaway between the Java Sea and the Indian Ocean.

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

First fossil turtle from Hainan Island, China [PDF]

Research & Knowledge, 2015
Although Hainan Island is one of the richest regions for living turtle species in China, no fossil turtle had hitherto been discovered there. In this paper we report on a partial turtle shell from the Middle Pleistocene of Xinchong Cave, Changjing ...

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

Geological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

Geological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

Phylogeographic Pattern of the Assassin Bug Sycanus bifidus Inferred from Mitochondrial Genomes and Nuclear Genes

Biology
The assassin bug Sycanus bifidus has a wide distribution across southern China. This study explored its distribution and evolution by analyzing mitochondrial and nuclear ribosomal RNA genes, revealing how Pleistocene climate and geological changes shaped

Tectono‐Sedimentary Evolution of the Neogene İnegöl Basin (NW Anatolia): Constraints on Transtensional Basin Development at the Junction of the Western Anatolian Extensional Province and the North Anatolian Fault Zone

Geological Journal, EarlyView.
The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, EarlyView.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...
