Phylogenomics and Biogeography of the Eastern Asian–Eastern North American Disjunct Genus Hylodesmum (Fabaceae)

Biological Diversity, EarlyView.
Integrating data from plastid genomes, nrDNA, and 353 low‐copy nuclear genes, this study establishes a robust phylogenetic framework for Hylodesmum. This framework supports a taxonomic revision recognizing 18 species and reveals a complex pattern of bidirectional EA–ENA dispersal, with mammals as a plausible dispersal agent. ABSTRACT Phylogenomics with

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

Deep Underground Science and Engineering, EarlyView.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

Plastid phylogenomics of tribe Perseeae (Lauraceae) yields insights into the evolution of East Asian subtropical evergreen broad-leaved forests

BMC Plant Biology, 2022
Background The East Asian subtropical evergreen broad-leaved forests (EBLFs) harbor remarkable biodiversity. However, their historical assembly remains unclear.

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

Ecography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Characteristics of Lacustrine Diamictite and Analysis of Diagenetic Reservoir Facies in the Neogene Lower Youshashan Formation in the Dafengshan Tectonic Belt in the Qaidam Basin

Energy Science &Engineering, EarlyView.
Based on field outcrop data, core descriptions, comprehensive thin section data (plain, cast, and fluorescent), scanning electron microscopy, whole rock analysis via X‐ray diffraction, physical property tests, element logging, core recording, and oil pilot tests, we propose utilizing a mature and practical three component classification method for ...

Isotope geochronology and vertebrate paleontology in Mexico: Panorama and critical appraisal

Revista Mexicana de Ciencias Geológicas, 2018
The combined isotopic/paleontologic approach drove a qualitative leap in understanding Earth’s geologic history/evolution, yet, in spite of its early start, it is still not widely used in México.

Late Miocene Ostracoda from NW Libya [PDF]

Journal of Micropalaeontology, 1988
Abstract. Nine ostracod species from the Late Miocene Al Khums Formation (exposed 2 km north of Qabilat ash Shurfah, NW Libya) are described and illustrated in this paper. Of these, four species, namely Cytherella libyaensis, Actinocythereis spinosa, Keijella africana and Neomonoceratina miocaenica, are new; one was established by Doruk (1980), one by ...
