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.

The Astrophysical JournalThe measured rates of period change, $\dot{P}$ , in the signals of pulsating white dwarf stars are often interpreted as direct detections of structural changes from secular cooling.

People and Nature, EarlyView.Abstract The town of Gamba in southwest Gabon represents an exceptional example of how the development of an extractive industry (in this case oil production) may impact wild meat consumption in an area of global importance for biodiversity. Studies in the 1990s identified an active wild meat trade; however, no studies have been undertaken since, and ...

Predicted incidence of Jupiter-like planets around white dwarfs
Astronomy & AstrophysicsContext. Gas-giant planets and brown dwarfs have been discovered in large numbers around main-sequence stars and even evolved stars. In contrast, and despite ongoing imaging surveys using state-of-the-art facilities, only a handful of substellar ...

Towards an Understanding of the Atmospheres of Cool White Dwarfs
, 2012 Cool white dwarfs with Teff < 6000 K are the remnants of the oldest stars that existed in our Galaxy. Their atmospheres, when properly characterized, can provide valuable information on white dwarf evolution and ultimately star formation through the ...

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.

Five New Sirius-like White Dwarf–Main-sequence Star Systems with MagAO-X
The Astronomical JournalMost known white dwarfs in multiple systems with main-sequence stars have been discovered with M-type companions, because the white dwarf causes detectable UV excess and bluer colors than expected from a single M star.

Past, present and future of local crop evolution
PLANTS, PEOPLE, PLANET, EarlyView.Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

White Dwarfs in Wide Binaries: The Strong Effects of Stellar Evolution and Mass Loss
The Astrophysical JournalWe examine the statistics of main-sequence/main-sequence, main-sequence/white-dwarf, and white-dwarf/white-dwarf wide binaries at 10 ^2.5 –10 ^4 au separations in Gaia data.

From wild to tamed: Reimagining novel crops through omics and local plant diversity
PLANTS, PEOPLE, PLANET, EarlyView.The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.
