UV radiation and reduced rainfall: Legacy effects on litter and first-year decomposition in two Mediterranean evergreen shrubs

Environmental and Experimental Botany
Climatic models for the Mediterranean Basin predict higher ultraviolet (UV) radiation and drier conditions by century’s end, potentially altering litter traits, early-stage decomposition, and nutrient cycling. This study investigates how UV radiation (UV-

Hormonal regulation of crop adaptation to UV-B radiation stress: implications for UV-B-Resistant crop varieties and sustainable agriculture

Discover Agriculture
Ultraviolet-B (UV-B: 280–315 nm) radiation stress severely compromises crop quality and productivity, necessitating the development of effective adaptive mechanisms. For plants to coordinate these adaptive responses, hormonal control is crucial. However,

UV-radiation, apoptosis and skin.

Collegium antropologicum, 2011
Apoptosis or programmed cell death is a key function in regulating skin development, homeostasis and tumorigenesis. The epidermis is exposed to various external stimuli and one of the most important is UV radiation. The UVA and UVB spectra differ in their biological effects and in their depth of penetration through the skin layers.

"Halo nevi" and UV radiation.

Collegium antropologicum, 2010
Halo nevi, also termed Sutton nevi, are defined as benign melanocytic nevi that are surrounded by an area of depigmentation resembling a halo. Halo nevi are common in children and young adults, with a mean age at onset of 15 years. The incidence in the population is estimated to be approximately 1%. Affected individuals frequently have multiple lesions
