Climate‐Modulated Particle Toxicity: Acute Exposure to an Environmentally Informed Microplastic Mixture Induces Sex‐Dependent Systemic Reorganization in Swiss Mice

Environmental Toxicology, EarlyView.
ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

Geometric Embeddability of Complexes is ∃R-complete [PDF]

, 2021
We show that the decision problem of determining whether a given (abstract simplicial) k-complex has a geometric embedding in Rd is complete for the Existential Theory of the Reals for all d≥3 and k∈{d−1,d}.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Morphometric analysis of cirques in central Siberia's western Putorana Plateau: a proxy for palaeoclimate

Boreas, EarlyView.
A detailed morphometric analysis of 200 cirques across the western Putorana Plateau, central Siberia, was undertaken to investigate cirque development, reconstruct glaciers and infer palaeoclimatic conditions. Cirques are amphitheatre‐shaped landforms with mean length and widths of 936 and 1000 m, respectively, indicating a mature glacial landscape ...

Identifying the exposure of taxonomic, functional, and phylogenetic diversity of steppe birds to renewable energy development

Conservation Biology, EarlyView.
Abstract Biodiversity is globally threatened by human impacts, including land‐use transformation and climate change, which has prompted a rapid transition from fossil fuels to cleaner energy sources, such as photovoltaic (PV) energy. However, utility‐scale PV plants require vast areas and can lead to conflicts with biodiversity conservation, making ...

Conservation and management implications of genetic and geometric scale variation in the ancient fish giant featherback (Chitala lopis)

Journal of Fish Biology, EarlyView.
Abstract Giant featherback (Chitala lopis) is an ancient species of freshwater fish considered globally extinct until extant populations were re‐discovered in the Sundaland region of Indonesia in 2022. To improve management of the remaining populations, this study used genomic DNA and landmark‐based geometric morphometric analyses of fish scales to ...

Morphometry of the glenoid cavity and its correlation with selected geometric measurements of the scapula

Bangladesh Journal of Medical Science, 2017
Introduction: An understanding of the normal glenoid cavity morphometry is important in corroborating the basis of luxation at the glenohumeral joint (GHJ). This study was carried out to determine the morphomertic relationship of the glenoid cavity to joint stability and device models to estimateglenoid cavity dimensions ofthe scapular boneof Nigerian ...
