Macronutrient composition in pollen affects development and survival in wild bees

open access: yesPhysiological Entomology, EarlyView.
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

Comparative Analysis of Salinity Readings for Water Quality Monitoring between IoT-Based Sensor Systems and Refractometer

open access: yesJurnal Teknologi dan Sistem Informasi
Salinity is among the factors that affect aquaculture water quality, along with pH, temperature, dissolved oxygen (DO), and ammonia. The osmotic pressure is influenced by salinity, which directly affects the aquatic biota.

Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume

open access: yesPlant Biology, EarlyView.
Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.

Compact Digital Holography-Based Refractometer for Non-Invasive Characterization of Transparent Media

open access: yesOptics
This work presents a compact refractometric system based on In-Line Digital Holography (ILDH) for the non-invasive characterization of transparent media, encompassing both liquids and high-refractive-index optical glasses.

Field‐based evaluation of glass cullet as a supplementary sediment source for coastal restoration

open access: yesRestoration Ecology, EarlyView.
There is an ever‐increasing demand for sand to support projects like beach nourishment and dune restoration, but dredging and mining sand causes environmental damage. Demonstrating the environmental and ecological compatibility of crushed and ground glass known as cullet to support coastal restoration projects could simultaneously divert waste from ...

An airborne system for detection of volcanic surface deformations [PDF]

open access: yes
A technique is proposed for measuring volcanic deformation on the order of centimeters per day to centimeters per year. An airborne multifrequency pulsed radar, tracking passive ground reflectors spaced at 1 kilometer intervals over a 50 square kilometer

Effect of internal and external cooling on high‐intensity intermittent cycling performance and cognitive function in the heat

open access: yesExperimental Physiology, EarlyView.
Abstract We investigated the effect of internal and external cooling on high‐intensity intermittent cycling performance and cognitive function in the heat. Twenty‐nine males completed a control trial (CON) and a cooling trial (ice slurry and ice collar; COOL) in the heat (33°C, 50% relative humidity) involving a 40 min intermittent cycling protocol ...

No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

open access: yesExperimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Effect of live‐high, train‐low strategy induced by chronic low‐dose carbon monoxide exposure on haematological parameters and performance in trained individuals

open access: yesExperimental Physiology, EarlyView.
Abstract Altitude training enhances haematological adaptations and endurance at sea level, typically requiring exposure to ∼2500 m altitude for 3–4 weeks. Emerging evidence suggests that low‐dose carbon monoxide (CO) inhalation might mimic hypoxia and might be used by elite athletes.

The effect of repeated hot water immersion on microvascular function, glycaemic control and inflammation in White European and South Asian males

open access: yesExperimental Physiology, EarlyView.
Abstract Individuals of South Asian (SA) descent display a higher risk for cardiovascular disease and type 2 diabetes mellitus than their White European (WE) counterparts. Heat therapy, such as hot water immersion (HWI), can improve microvascular function and glycaemic control, although effects across racial groups are unknown.
