Research on the penetration characteristics of coral sand based on a visco-hypoplastic constitutive model

open access: yesCase Studies in Construction Materials
This study investigates the penetration characteristics of coral sand based on hypoplasticity theory. The Gudehus-Bauer (GB) hypoplastic constitutive model was optimized by modifying the particle hardness parameter to incorporate strain rate effects ...

Solenostomus snuffleupagus sp. nov., a hairy ghost pipefish (Teleostei: Solenostomidae) from the Southwest Pacific, with an integrative comparison to S. paegnius

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of ghost pipefish, Solenostomus snuffleupagus sp. nov., is described from the Coral Sea based on specimens (18–34 mm SL) collected from coral reef habitats in Queensland, Australia. The species is diagnosed by the following combination of characters: abundant elongate integumentary filaments imparting a conspicuously shaggy ...

Experimental Study on the Influence of Particle Gradation on the Resistivity Characteristics of Saturated Coral Sand

open access: yesJournal of Marine Science and Engineering
Due to the action of hydraulic sorting, coral sands in different engineering site areas usually have different particle gradations. To explore the impact of particle gradation on the resistivity characteristics of saturated coral sand, an experimental ...

Non‐Additive Interactions Between Multiple Mutualists and Host Plant Genotype Simultaneously Promote Increased Plant Growth and Pathogen Defence

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Understanding the impact of microbial interactions on plants is critical for maintaining healthy native ecosystems and sustainable agricultural practices. Despite the reality that genetically distinct plants host multiple microbes of large effect in the field, it remains unclear the extent to which host genotypes modulate non‐additive ...

Ecological divergence in the silver moss Bryum argenteum: developmental, ontogenetic and life‐history trait variations across contrasting tropical ecosystems

open access: yesPlant Biology, EarlyView.
Ecotypes of the cosmopolitan moss Bryum argenteum differ markedly in growth, reproductive timing, and allocation across contrasting tropical ecosystems. These patterns reveal strong environment‐ and sex‐dependent life‐history strategies, highlighting the species as a model for studying ecological divergence in bryophytes.
