Validation of Sea Surface Temperature Derived From Himawari-8 by JAXA

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Hourly sea surface temperature (SST) retrieved from Himawari-8 by the Japan Aerospace Exploration Agency (H8-SST/JAXA, latest version 1.2) is becoming an important data source for data merging as well as for resolving diurnal variation (DV). However, the

Temporal Variation of Aristolochia chilensis Aristolochic Acids during Spring

open access: yesMolecules, 2015
In this communication, we report the springtime variation of the composition of aristolochic acids (AAs) in Aristolochia chilensis leaves and stems. The dominant AA in the leaves of all samples, which were collected between October and December, was AA-I

In situ Orchid Seedling-Trap Experiment Shows Few Keystone and Many Randomly Associated Mycorrhizal Fungal Species During Early Plant Colonization

open access: yesFrontiers in Plant Science, 2018
Orchids are known for their vast diversity and dependency on mycorrhizal fungi. Under in situ conditions, the biotic and abiotic factors determining the composition and distribution of orchid mycorrhizal fungi (OMF) communities remain largely unexplored.

Spatial and temporal distribution characteristics of ground-level nitrogen dioxide and ozone across China during 2015–2020

open access: yesEnvironmental Research Letters, 2021
In recent years, the emissions control in nitrogen oxides (NO _x ) was conducted across China, but how the concentrations of NO _x and its product ozone (O _3 ) in the atmosphere varied in space and time remains uncertain.

Temporal Variation in the Microbiome of Acropora Coral Species Does Not Reflect Seasonality

open access: yesFrontiers in Microbiology, 2019
The coral microbiome is known to fluctuate in response to environmental variation and has been suggested to vary seasonally. However, most studies to date, particularly studies on bacterial communities, have examined temporal variation over a time frame ...

Assessing dietary adequacy and temporal variability in the context of Covid-19 among Indigenous and rural communities in Kanungu District, Uganda: a mixed-methods study

open access: yesEnvironmental Research: Health, 2023
Dietary adequacy is hard to achieve for many people living in low-income countries, who suffer from nutritional deficiencies. Climate change, which alters weather conditions, has combined with other cascading and compound events to disrupt Indigenous ...
