Does pyrogenicity protect burning plants?

Pyrogenic plants dominate many fire-prone ecosystems. Their prevalence suggests some advantage to their enhanced flammability, but researchers have had difficulty tying pyrogenicity to individual-level advantages. Based on our review, we propose that enhanced flammability in fire-prone ecosystems should protect the belowground organs and nearby propagules of certain individual plants during fir...

Ultraviolet Radiation and Plants: Burning Questions.

Plants use sunlight for photosynthesis and, as a consequence, are exposed to the ultraviolet (UV) radiation that is present in sunlight. UV radiation is generally divided into three classes: UV-C, UV-6, and UV-A. The UV-C region of the UV spectrum includes wavelengths below 280 nm; these highly energetic wavelengths are effectively absorbed by ozone in the stratosphere and, thus, are not presen...

On the Optimization of Peat Burning Plants

One source of energy, the importance of which has been realized with the advance of increasing fuel prices, is peat, a renewing resource of nature typical for some areas in northern Europe. Because of the comparatively difficult processing properties of peat and the quite short history of efficient development on this area the technology of peat burning plants now needs a systematic programme o...

Does reproduction protect against oxidative stress?

A central principle of life-history theory is that parents trade investment in reproduction against that in body maintenance. One physiological cost thought to be important as a modulator of such trade-off is oxidative stress. Experimental support for this hypothesis has, however, proved to be contradictory. In this study, we manipulated the nestling rearing effort of captive canaries (Serinus ...
