The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

open access: yesThe Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

open access: yesThe Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

Adaptive Genomic Divergence Across Altitudes in Capsella bursa‐pastoris

open access: yesBiological Diversity, EarlyView.
Genomic divergence was observed between high‐altitude and low‐altitude populations of Capsella bursa‐pastoris in China, consistent with an important role of ecological factors. Candidate adaptive loci associated with enhanced energy metabolism, photoprotection, and growth plasticity under altitudinal stress were identified.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Extent, characteristics and policy applications of Key Biodiversity Areas

open access: yesBiological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Impact of Intermediate Wheatgrass an Adjunct Ingredient on the Chemical Composition and Development of Aroma Compounds in Sake Brewing

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background Replacing a portion of polished rice with intermediate wheatgrass (IWG) could diversify raw materials for sake, but its effects on composition and fermentation outcomes are not well characterized. The objective of this study was to quantify how adjunct form (whole vs.

Seasonal Spatial Population Density Distribution Dynamics of Lynx and Ungulate Prey in Cold‐Temperate Coniferous Forests 寒温带针叶林猞猁和有蹄类猎物种群密度空间分布的季节性动态研究

open access: yesIntegrative Conservation, EarlyView.
This study used camera trap data from 6 years between 2016 and 2021 and generalized linear mixed models to explore the factors that influence the spatial density distribution of lynx and its prey populations in warm and cold seasons in Inner Mongolia Hanma National Nature Reserve, China.

Astragalus ecomorphology in Quaternary elephantids

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

open access: yesNordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Landscape diversity facilitates population growth and abundance of polyphagous Lygus pratensis in cotton fields of northern Xinjiang

open access: yesNew Plant Protection, EarlyView.
Increased landscape diversity showed significantly positive effects on the population growth rate and abundance of polyphagous Lygus pratensis in cotton fields, which may be attributed to the enhanced continuity and heterogeneity of host plant resources in more diverse agricultural landscapes.
