Long-Term Evolution of the Saturnian System. [PDF]

Space Sci Rev
Here we present the current state of knowledge on the long-term evolution of Saturn’s moon system due to tides within Saturn. First we provide some background on tidal evolution, orbital resonances and satellite tides.

Long‐Term Evolution Under Heatwave Conditions in the Seed Beetle, Callosobruchus maculatus [PDF]

Ecology and Evolution
Heatwaves, temporary periods of elevated temperatures, are increasing in both magnitude and frequency and have devastating effects on many taxa. However, to date, most studies investigating the impacts of heatwaves have focused on populations that have ...

Recent progress on the long‐term stability of hydrogen evolution reaction electrocatalysts

InfoMat, 2022
Developing new methodologies to produce clean and renewable energy resources is pivotal for carbon‐neutral initiatives. Hydrogen (H2) is considered as an ideal energy resource due to its nontoxic, pollution‐free, high utilization rate, and high calorific

Repeating tidal disruptions in GSN 069: Long-term evolution and constraints on quasi periodic eruptions models [PDF]

Astronomy & Astrophysics, 2022
GSN 069 is the first galactic nucleus where quasi-periodic eruptions (QPEs) have been identified. These are high-amplitude, soft X-ray bursts recurring every ~9 hr, lasting ~1 hr, and during which the X-ray count rate increases by up to two orders of ...

The Long-Term Evolution of the Atmosphere of Venus: Processes and Feedback Mechanisms [PDF]

Space Science Reviews, 2022
This work reviews the long-term evolution of the atmosphere of Venus, and modulation of its composition by interior/exterior cycling. The formation and evolution of Venus’s atmosphere, leading to contemporary surface conditions, remain hotly debated ...

The evolution of courtship displays in Galliformes

Avian Research, 2022
Species in Galliformes have elaborate ritual courtship displays, often including strutting, fluffing of tail or head feathers, and vocal sounds that serve as excellent examples of sexual selection.

From the ground up: Building predictions for how climate change will affect belowground mutualisms, floral traits, and bee behavior

Climate Change Ecology, 2021
Climate change affects species and their interactions, resulting in novel communities and modified ecosystem processes. Through shifts in phenology and distribution, climatic change can disrupt interactions, including those between mutualists. Mutualisms

Long-term evolution of ocean eddy activity in a warming world

Nature Climate Change, 2022
Mesoscale ocean eddies, an important element of the climate system, impact ocean circulation, heat uptake, gas exchange, carbon sequestration and nutrient transport. Much of what is known about ongoing changes in ocean eddy activity is based on satellite

Long-term evolution of multiple sclerosis iron rim lesions in 7 T MRI.

Brain : a journal of neurology, 2021
Recent data suggest that multiple sclerosis white matter lesions surrounded by a rim of iron containing microglia, termed iron rim lesions, signify patients with more severe disease course and a propensity to develop progressive multiple sclerosis.
