Speleothem and biofilm formation in a granite/dolerite cave, Northern Sweden

International Journal of Speleology, 2014
Tjuv-Antes grotta (Tjuv-Ante's Cave) located in northern Sweden is a round-abraded sea cave ('tunnel cave'), about 30 m in length, formed by rock-water abrasion in a dolerite dyke in granite gneiss. Abundant speleothems are restricted to the inner, mafic

CT-Informed Skull Osteology of Palaeolagus haydeni (Mammalia: Lagomorpha) and Its Bearing on the Reconstruction of the Early Lagomorph Body Plan

Frontiers in Ecology and Evolution, 2021
Lagomorpha is a clade of herbivorous mammals nested within Euarchontoglires, one of the major placental groups represented today. It comprises two extant families with markedly different body plans: the long-eared and long-limbed Leporidae (hares and ...

The Roles of Renewable Energy and Natural Resources in Shaping a Greener Switzerland: A Consumption‐Side Perspective

Geological Journal, EarlyView.
ABSTRACT This research intends to examine how renewable energy (REN) consumption and natural resource (RES) rents affect the environmental impact of consumption in Switzerland. Along with REN and RES, the study considers Information and Communication Technology (ICT) and participatory democracy as other independent variables of interest.

Atmospheric Consequences of Cosmic Ray Variability in the Extragalactic Shock Model II: Revised ionization levels and their consequences

, 2010
It has been suggested that galactic shock asymmetry induced by our galaxy's infall toward the Virgo Cluster may be a source of periodicity in cosmic ray exposure as the solar system oscillates perpendicular to the galactic plane.

A Review of the Paleobiology of Some Neogene Sharks and the Fossil Records of Extant Shark Species

Diversity
In recent years, new findings and new methods (stable isotopes of oxygen, zinc, and nitrogen; 2D and 3D modeling; and geometric morphometric analyses of the teeth) have enhanced our knowledge of the Neogene shark fauna and its paleobiology.

Early Cretaceous–Late Miocene Basin–Mountains Pattern in the Northeastern Margin of the Tibetan Plateau, NW China: Evidence From Detrital Zircon Chronology in the Lanzhou Basin

Geological Journal, EarlyView.
Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

Molecular and fossil evidence place the origin of cichlid fishes long after Gondwanan rifting. [PDF]

, 2013
Cichlid fishes are a key model system in the study of adaptive radiation, speciation and evolutionary developmental biology. More than 1600 cichlid species inhabit freshwater and marginal marine environments across several southern landmasses.

Smart Solutions for Sustainable Access and Technological Equity: The Effect of Energy Transition, Artificial Intelligence, and Digital Economy on Energy Poverty

Geological Journal, EarlyView.
ABSTRACT The integration of energy transition, artificial intelligence, and the digital economy represents a significant shift in the global effort to combat energy poverty and offers innovative tools and approaches to increase energy access, efficiency, and affordability for underserved populations. This study examines the impact of energy transition,

Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

Geological Journal, EarlyView.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Using abundance data to assess the relative role of sampling biases and evolutionary radiations in Upper Muschelkalk ammonoids [PDF]

, 2011
The Middle Triassic ammonoid genus Ceratites diversified spectacularly within the Germanic Muschelkalk Basin during the Anisian/Ladian (244–232 Mya). Previous studies have interpreted this diversification as a sequence of rapid, endemic radiations from a
