Relationships between Plant Diversity and Grasshopper Diversity and Abundance in the Little Missouri National Grassland

open access: yesPsyche: A Journal of Entomology, 2011
A continuing challenge in orthopteran ecology is to understand what determines grasshopper species diversity at a given site. In this study, the objective was to determine if variation in grasshopper abundance and diversity between 23 sites in western ...

Elevational patterns of bird species richness on the eastern slope of Mt. Gongga, Sichuan Province, China

open access: yesAvian Research, 2019
Background In biological systems, biological diversity often displays a rapid turn-over across elevations. This defining feature has made mountains classic systems for studying the spatial variation in diversity. Because patterns of elevational diversity

Osteocytes under Mechanical Loading Regulate PC‐3 Cancer Cell–Mineral Interactions during Early‐Stage Metastasis to Bone

open access: yesAdvanced Biology, EarlyView.
In this study, Seaman et al. develop a co‐culture assay to examine interactions between prostate cancer cells and mineralized osteoblasts in a microfluidic platform. The authors collect conditioned media from static or flow‐stimulated osteocytes and demonstrate that mechanical loading of osteocytes regulates the growth of prostate cancer cells and ...

Machine Learning Applied to High Entropy Alloys under Irradiation

open access: yesAdvanced Engineering Materials, EarlyView.
Designing alloys for extreme environments demands fast, trustworthy prediction. This review charts how machine learning—especially machine‐learned interatomic potentials and predictive models based on experiment‐informed datasets—captures the complexity of high‐entropy alloys in extreme environments, predicts phase formation, mechanical properties, and

Seed sowing shifts native–exotic richness relationships in favor of natives during restoration

open access: yesEcosphere
A central goal of ecological restoration is to promote diverse ecosystems dominated by native species, but restorations are often plagued by exotic species.

Electrospark‐Deposited AlCrFeCoNi High‐Entropy Alloy Coatings on Steel: Microstructure Evolution, Mechanical Properties, and Corrosion Response

open access: yesAdvanced Engineering Materials, EarlyView.
AlCrFeCoNi high entropy alloy coating is applied on steel using electrospark deposition. The microstructure evolution and phase transformation of the as‐deposited and heat‐treated coatings is characterized and discussed. Reduced microhardness and yield strength are measured after heat treatment.

Tropical rainforest bird community structure in relation to altitude, tree species composition, and null models in the Western Ghats, India

open access: yes, 2005
Studies of species distributions on elevational gradients are essential to understand principles of community organisation as well as to conserve species in montane regions.

Micromechanical Characterization of 316L‐V4E Steel Transitions Produced by Electron Beam Powder Bed Fusion with Dual‐Hopper Alternating Layer Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
This work applies High‐Speed Nanoindentation to study multi‐material transitions in powder bed fusion–electron beam melting components. The aim is to assess the mechanical gradients and interfacial behavior between American iron and steel institute 316L stainless steel and V4E tool steel in additively manufactured structures.
