Limnology and Oceanography, EarlyView.Abstract Boreal lakes are generally seen as sources of carbon dioxide (CO2) to the atmosphere, even though a part of them are periodically undersaturated with CO2 and have the potential to be net‐autotrophic. This undersaturation is the result of photosynthetic activity by phytoplankton, especially flagellated species like Gonyostomum semen, which form

TOI-1994b: A Low-mass Eccentric Brown Dwarf Transiting A Subgiant Star
The Astronomical JournalWe present the discovery of TOI-1994b, a low-mass brown dwarf transiting a hot subgiant star on a moderately eccentric orbit. TOI-1994 has an effective temperature of ${7700}_{-410}^{+720}$ K, V magnitude of 10.51 mag and log( g ) of ${3.982}_{-0.065 ...

Volcanic soils alleviate the allelopathic capacity of Empetrum nigrum in degraded tundra ecosystems
Oikos, EarlyView.Land degradation due to unsustainable land use is of major concern worldwide and recovery is often slow. A potential mechanism behind slow recovery of degraded ecosystems is the retarding impacts of allelopathic plant species on the establishment of species that might facilitate the recovery process.

Precise Mass, Orbital Motion, and Stellar Properties of the M-dwarf Binary LP 349−25AB
The Astrophysical JournalLP 349−25 is a well-studied close stellar binary system comprised of two late M dwarf stars, where both stars are close to the limit between star and brown dwarf. This system was previously identified as a source of gigahertz radio emission.

People and Nature, EarlyView.Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Barriers and Enablers: Teachers' Views on Mental Health Assessment in Ireland's Primary Schools
Psychology in the Schools, EarlyView.ABSTRACT Mental health problems in school‐age children continue to be a major concern internationally. The school setting has increasingly been viewed as having a potential role in supporting the assessment of children's mental health, yet there is a paucity of studies which examine teachers' perceptions of this.

Brown dwarfs in Eddington-inspired Born-Infeld and beyond Horndeski theories
European Physical Journal C: Particles and Fields, 2019 We studied herein the mass and the radius of brown dwarfs predicted by beyond Horndeski (BH) and Eddington-inspired Born-Infeld (EiBI) gravity theories by numerically solving the modified non-relativistic hydrostatic equations of both theories. We used a
