Identification of senescence and death in Emiliania huxleyi and Thalassiosira pseudonana: Cell staining, chlorophyll alterations, and dimethylsulfoniopropionate (DMSP) metabolism [PDF]

, 2012
We measured membrane permeability, hydrolytic enzyme, and caspase-like activities using fluorescent cell stains to document changes caused by nutrient exhaustion in the coccolithophore Emiliania huxleyi and the diatom Thalassiosira pseudonana, during ...

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

Oikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

The fitness of pelargonium cuttings affects the relationship between the photochemical activity of the photosynthetic apparatus and rooting ability

Scientific Reports
Pelargoniums cultivated for ornamental purposes rely on efficient vegetative propagation. This study researched applicability of chlorophyll fluorescence for validating the physiological conditions of pelargonium cuttings. Results indicated a correlation

Detection of the tulip breaking virus (TBV) in tulips using optical sensors [PDF]

, 2009
The tulip breaking virus (TBV) causes severe economic losses for countries that export tulips such as the Netherlands. Infected plants have to be removed from the field as soon as possible.

Trait convergence under warming: drought tolerance, not thermal limits, mediates native–invader dynamics in alpine ecosystems

Oikos, EarlyView.
Climate warming and plant invasions jointly alter alpine ecosystems, but the mechanisms underlying these interactions remain unclear. A key to predicting ecosystem vulnerability is whether native and invasive species can sustain performance as conditions warm.

Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

PLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

Chlorophyll fluorescence technique as a rapid diagnostic test of the effects of the photosynthetic inhibitor chlorotoluron on two winter wheat cultivars

, 2003
A modified chlorophyll fluorescence technique was evaluated as a rapid diagnostic test of the susceptibility of wheat cultivars to chlorotoluron. Two winter wheat cultivars (Maris Huntsman and Mercia) exhibited differential response to the herbicide. All

Synergistic benefits of agrivoltaics for grape production and solar energy efficiency in a Mediterranean vineyard

PLANTS, PEOPLE, PLANET, EarlyView.
Grapevine production is increasingly challenged by global warming, with global wine output falling to a six‐decade low in 2024. At the same time, the vine and wine sector faces growing pressure to reduce its carbon footprint. Agrivoltaics, which integrates solar photovoltaic (PV) modules into plant production systems, offers a potential pathway to ...
