Semiarid grassland responses to short-term variation in water availability

Variation in short-term and long-term responses of photosynthesis and isoprenoid-mediated photoprotection to soil water availability in four Douglas-fir provenances

For long-lived forest tree species, the understanding of intraspecific variation among populations and their response to water availability can reveal their ability to cope with and adapt to climate change. Dissipation of excess excitation energy, mediated by photoprotective isoprenoids, is an important defense mechanism against drought and high light when photosynthesis is hampered. We used 50...

Short Communication: Haematological and immunological responses of sea bass (Dicentrarchus labrax) to a short-term exposure to increased water levels of nitrate

Short Communication: Haematological and immunological responses of sea bass (Dicentrarchus labrax) to a short-term exposure to increased water levels of nitrate

Convergent responses of nitrogen and phosphorus resorption to nitrogen inputs in a semiarid grassland.

Human activities have significantly altered nitrogen (N) availability in most terrestrial ecosystems, with consequences for community composition and ecosystem functioning. Although studies of how changes in N availability affect biodiversity and community composition are relatively common, much less remains known about the effects of N inputs on the coupled biogeochemical cycling of N and phos...

Short-term physiological and developmental responses to nitrogen availability in hybrid poplar.

Nitrogen fertilization induces dramatic changes in the growth and development of plants, including forest trees. In this study we examined short-term responses of hybrid poplar, Populus balsamifera ssp. trichocarpa x deltoides, to N fertilization. Glasshouse-grown saplings subjected to limiting, intermediate, and luxuriant levels of ammonium nitrate over a 28 d time course demonstrated rapid ch...
