Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Revisiting the Activity–Rotation Relation for Evolved Stars

The Astrophysical Journal
The magnetic dynamo mechanism of giant stars remains an open question, which can be explored by investigating their activity–rotation relations with multiple proxies. By using the data from the LAMOST and Galaxy Evolution Explorer surveys, we carried out

Measuring the core rotation of red giant stars

, 2016
Red giant stars present mixed modes, which behave as pressure modes in the convective envelope and as gravity modes in the radiative interior. This mixed character allows to probe the physical conditions in their core.

Diversity of Amphidomataceae (Dinophyceae) in the Black Sea, including description of Amphidoma pontica sp. nov.

Phycological Research, EarlyView.
SUMMARY The dinoflagellate family Amphidomataceae includes the genera Azadinium and Amphidoma, several species of which are known producers of lipophilic toxins known as azaspiracids (AZAs). However, the diversity, abundance, and distribution of this important group of nanoplanktonic dinoflagellates in the Black Sea remain poorly understood. To address

Mining the GALAH Data. I. Study of Five Super Lithium-rich Metal-poor Giants

The Astrophysical Journal
The presence of a large amount of Li in giants is still a mystery. Most of the super Li-rich (SLR) giants reported in recent studies are in the solar metallicity regime.
