Photosynthetic responses of heat-stressed apple leaves to foliar application of salicylic and ascorbic acid

open access: yesPhotosynthetica
High temperatures have significant impacts on fruit tree production. Foliar spraying application of promoting agents can be a sustainable approach to managing high-temperature stress in orchards.

Variability of nutrients and chlorophyll a in Ancão Inlet during a spring tidal cycle in April 2009

open access: yesCiencias Marinas, 2011
São Luis or Ancão Inlet is the most western of the six inlets of the Ria Formosa lagoon, in southern Portugal. This inlet contributes relatively little to the water volume exchange over a tidal cycle (~10%).

Characterization of a trimeric light-harvesting complex in the diatom Phaeodactylum tricornutum built of FcpA and FcpE proteins [PDF]

open access: yes, 2010
Fucoxanthin chlorophyll proteins (Fcps), the light-harvesting antennas of heterokont algae, are encoded by a multigene family and are highly similar with respect to their molecular masses as well as to their pigmentation, making it difficult to purify ...

The statistical power to detect cross‐scale interactions at macroscales

open access: yesEcosphere, 2016
Macroscale studies of ecological phenomena are increasingly common because stressors such as climate and land‐use change operate at large spatial and temporal scales. Cross‐scale interactions (CSIs), where ecological processes operating at one spatial or

Validation of Stratification-Driven Phytoplankton Biomass and Nutrient Concentrations in the Northeast Atlantic Ocean as Simulated by EC-Earth

open access: yesGeosciences, 2019
We validated simulations of the Earth system model (ESM) EC-Earth-NEMO of present-day temperature, salinity, nutrient, and chlorophyll a profiles with in situ observations in the Northeast Atlantic Ocean (29−63º N).

Two-Dimensional Electronic Spectroscopy of Chlorophyll a: Solvent Dependent Spectral Evolution [PDF]

open access: yes, 2015
The interaction of the monomeric chlorophyll Q-band electronic transition with solvents of differing physical-chemical properties is investigated through two-dimensional electronic spectroscopy (2DES). Chlorophyll constitutes the key chromophore molecule

Development of a handheld chlorophyll content detector on wheat and maize leaves based on RGB sensor

open access: yesFrontiers in Plant Science
Chlorophyll-a (CL-a) and chlorophyll-b (CL-b) are major chlorophyll found in green plants. Determining the CL-a, CL-b, and total chlorophyll (TCL) contents is important to guide crop growth.

Water temperature and chlorophyll a density drive the genetic and epigenetic variation of Vallisneria natans across a subtropical freshwater lake

open access: yesEcology and Evolution, 2023
Plant genetic diversity differs in habitat's oscillations, especially species distributed under heterogeneous environmental conditions. Freshwater ecosystems are vulnerable to biotic and abiotic impacts, which affect the genetic and epigenetic variations

Water quality characteristics of Poyang Lake, China, in response to changes in the water level

open access: yesHydrology Research, 2016
As one of the few remaining lakes that are freely connected with the Yangtze River, Poyang Lake exhibits large annual water level (WL) fluctuations.
