A notable new narrow‐endemic species of Jurinea (Asteraceae) from the subalpine region of western Iran

Nordic Journal of Botany, EarlyView.
Extensive field studies in remote areas of Chaharmahal and Bakhtiari Province, Iran, resulted in the identification of a novel Jurinea species (Asteraceae: subtribe Saussureinae). Jurinea kuhrangensis sp. nov., a chasmophytic species endemic to limestone outcrops in the subalpine region of Kuhrang County, is formally documented in this study ...

Optical Spectroscopy of the Most Compact Accreting Binary Harboring a Magnetic White Dwarf and a Hydrogen-rich Donor

The Astrophysical Journal Letters
Accreting white dwarfs (WDs) in close binary systems, commonly known as cataclysmic variables (CVs), with orbital periods below the canonical period minimum (≈80 minutes) are rare.

Fly pollinator foraging in boreal forests is shaped by climate, forest structure and flower resources

Oikos, EarlyView.
Most insect pollinators are ectothermic and rely on external heat sources for temperature regulation. Forests, with their diverse canopy structures and sunlight penetration levels, create a mosaic of microclimates influencing these insects' behaviour.

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

Oikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

The Fate of Oceans on First-generation Planets Orbiting White Dwarfs

The Astrophysical Journal
Several groups have recently suggested that small planets orbiting very closely around white dwarf stars could be promising locations for life to arise, even after stellar death.
