The impact of isosmotic conditions on the metabolism and hypoxia tolerance of a reportedly oxyconforming teleost

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fish must manage the competing demands of ion balance and gas exchange across the gills – a physiological tension known as the osmorespiratory compromise. In dynamic estuarine environments, the osmorespiratory compromise may be exacerbated by variable salinity and periods of hypoxia that demand high respiratory work.

The multidimensional regulation roles and mechanisms of calcium in fruit quality

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

The Eucalyptus grandis NBS-LRR gene family: physical clustering and expression hotspots

open access: yesFrontiers in Plant Science, 2016
Eucalyptus grandis is a commercially important hardwood species and is known to be susceptible to a number of pests and pathogens. Determining mechanisms of defense is therefore a research priority. The published genome for E.

Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination

open access: yesJournal of Integrative Plant Biology, EarlyView.
Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

open access: yesJournal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

A novel dental implant nut system designed to enhance primary stability: Mechanical and finite element analysis

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The present study aimed to evaluate, in a preclinical setting, the biomechanical behavior and mechanical performance of a newly developed dental implant nut system designed to address primary stability challenges in the severely resorbed posterior maxilla.

Influence of vapour pressure deficit and CO2 on the thermal sensitivity of stomatal function in tropical trees

open access: yesNew Phytologist, EarlyView.
Examining the potential thermal sensitivity of the model parameter g1 when accounting for the additive nature of underlying components including CO2 compensation point (Г*) and the marginal water cost of plant carbon gain (λ), when assuming λ is dependent upon changes in the viscosity (inverse of fluidity) of water (η, Pa·s) and the solubility of CO2 ...
