Cryptic Ice Wedge Networks in Holocene Peat, Yukon‐Kuskokwim Delta, Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Yukon‐Kuskokwim Delta (YKD), covering ~75,000 km2 of Alaska's discontinuous permafrost zone, has a historic (1902–2023) mean annual air temperature of ~−1°C and was previously thought to lack ice wedge networks. However, our recent investigations near Bethel, Alaska, revealed numerous near‐surface ice wedges.

The women honoured in flowering plant genera: From myth to reality

PLANTS, PEOPLE, PLANET, EarlyView.
Many flowering plant genera are named for people, but there is a gender gap in this naming, with only 6% of eponyms honouring women. Here we explore this gap by examining in detail women for whom plant genera are named. Our open shared dataset serves to make women honoured in plant genera more discoverable, resulting in further impact by allowing ...

Brown Dwarf Binaries [PDF]

Proceedings of the International Astronomical Union, 2011
AbstractNearly 500 brown dwarfs have been discovered in recent years. The majority of these brown dwarfs exist in the solar neighborhood, yet determining their fundamental properties (mass, age, temperature & metallicity) has proved to be quite difficult, with current estimates relying heavily on theoretical models.

Recognising Seaweeds: Addressing Gaps in International Biodiversity Frameworks for Global Seaweed Conservation

Sustainable Development, EarlyView.
ABSTRACT As anthropogenic pressures increasingly impact marine ecosystems and the biodiversity they support, governance mechanisms for international biodiversity conservation have emerged. Seaweed habitats are important repositories for marine biodiversity, and they provide crucial ecosystem services that support both ocean and human health.

WZ SGE STARS

Odessa Astronomical Publications, 2007
The WZ Sge type stars is a rare subclass of the cataclysmic variables (CVs). It possesses the properties of both dwarf novae and recurrent novae. The WZ Sge stars have the shortest orbital periods (typically 80 - 90 minutes) known among the dwarf novae ...
