The myth of the metabolic baseline: sleep–wake cycles undermine a foundational assumption in organismal biology

Biological Reviews, EarlyView.
ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

The Diurnal Variations of GPS PWV near Poyang Lake in China during Midsummer

Advances in Meteorology, 2020
With the 1 h-averaged data of atmospheric precipitable water vapor (PWV) for 2015–2018 retrieved from 18 ground-based Global Positioning System (GPS) observation stations near Poyang Lake (PL), China, the diurnal variations of the PWV during midsummer ...

Hydroxyl Self‐Trapping Strategy Enables Electrocatalysis at Ampere‐Level Current Densities: Kinetics‐Driven Lattice Oxygen Activation for Cl−‐Rich Alkaline Water Electrooxidation

Carbon Energy, EarlyView.
This study designs a CrOx‐engineered Ni‐based catalyst enabling efficient and stable seawater electrolysis. The catalyst utilizes a dynamic interfacial barrier that selectively adsorbs OH− to repel Cl− corrosion while activating lattice oxygen‐mediated pathways.

Temperature variations in simulated warming alter photosynthesis of two emergent plants in plateau wetlands, China

Ecosphere, 2019
Understanding the impact of temperature variations (i.e., maximum, minimum, and diurnal temperature ranges [DTRs]) on ecosystems is now recognized as being of paramount importance in global change ecology; the roles of different aspects of these ...

Dial variations in temperature, salinity and dissolved oxygen from the neritic waters off Cochin during April (peak summer) [PDF]

, 1996
Dial variations of important hydrographic parameters were studied continuously for 7 days at a 100 m depth station off Cochin. The frequency of observations varied from 1-3 hourly intervals.

In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio

Chemie Ingenieur Technik, EarlyView.
The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from

Evaluating the Variability of Urban Land Surface Temperatures Using Drone Observations [PDF]

, 2019
Urbanization and climate change are driving increases in urban land surface temperatures that pose a threat to human and environmental health. To address this challenge, we must be able to observe land surface temperatures within spatially complex urban ...

Reversible Phase‐Change‐Induced Transparency Switching and Dynamic Thermal Regulation Gel for Energy‐Efficient Smart Windows

EcoEnergy, EarlyView.
The phase transition process imparts shape‐stable gels with the capability of reversible transparency modulation and temperature‐responsive heat storage and release. When applied to smart windows, this property ensures the maintenance of thermal energy within the human thermal comfort zone, thereby facilitating indoor energy conservation.

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...
