Seasonal variation of leaf functional traits in sub‐Arctic plants
Oikos, EarlyView.Leaf functional traits are informative of plant fitness and functions in ecosystems. These functional traits and their variation across geographic extents are much studied but less is known about their temporal variation over a growing season. Here, we provide an analysis of the seasonal variation in six leaf functional traits of 11 sub‐Arctic vascular

The Astrophysical JournalPlanets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches. However, since the white dwarf habitable zone resides at 0.01–0.1 au, planets residing there are subject to tidal heating ...

Oikos, EarlyView.Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Using 3.4 μm Variability toward White Dwarfs as a Signpost of Remnant Planetary Systems
The Astrophysical JournalRoughly 2% of white dwarfs harbor planetary debris disks detectable via infrared excesses, but only a few percent of these disks show a gaseous component, distinguished by their double-peaked emission at the near-infrared calcium triplet.

People and Nature, EarlyView.Abstract For many people around the world, especially in Indigenous communities, seasonal changes affect the availability and desirability of different types of food. Assessing the relationship between seasonality, sociocultural preferences and hunting patterns is vital for understanding how these populations harness seasonal food production dynamics ...

Prenatal Diagnosis, EarlyView.ABSTRACT In utero interventions are transformative in addressing genetic and anatomic conditions during fetal development. Next generation sequencing enables early genetic testing, playing a pivotal role in prenatal decision‐making by supporting risk stratification, precise and timely diagnosis, which directly informs eligibility for fetal surgical and

A Short Intense Dynamo at the Onset of Crystallization in White Dwarfs
The Astrophysical Journal LettersThe origin of large magnetic fields (≳10 ^6 G) in isolated white dwarfs is not clear. One possible explanation is that crystallization of the star’s core drives compositional convection, which when combined with the star’s rotation, can drive a dynamo ...

PLANTS, PEOPLE, PLANET, EarlyView.Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.
