Climate Change Threatens Micronutrient Density of European Winter Wheat
Advanced Science, EarlyView.Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Advanced Science, EarlyView.A real‐world model of structured animal product restriction practiced for religious reasons reveals the dynamic adaptability of the human gut microbiome to dietary change and uncovers reductions in diversity and rare taxa loss. Integrated microbiome, metabolomic, and proteomic analyses uncover coordinated taxonomic and molecular shifts and identify ...

Effects of Various Photoperiods on Color and Pubescence in \u3ci\u3eThyanta Calceata\u3c/i\u3e (Hemiptera: Pentatomidae) [PDF]
, 2017 Rearing immatures of Thyanta calceata in a Iange of photoperiods showed that a threshold photoperiod is involved in the adult dimorphic response (color and pubescence) with the mean threshold near 12.5L: 11.5D.

Seasonal distribution of vitamin B12 in Lake Kinneret [PDF]
Applied and Environmental Microbiology, 1977 Vitamin B12 is formed in Lake Kinneret in the hypolimnion and in the sediment. The highest value of B12 recorded in the lake water was about 100 ng/liter in November and December of 1975 at a 40-m depth. The vitamin was liberated from the hypolimnion during the turnover period. This supply of the vitamin to the photic zone was accompanied by increasing

Coupled Above‐ and Belowground Ecosystem Stability Worldwide
Advanced Science, EarlyView.Are the worlds above and below our feet in sync? This global exploration reveals an entangled fate between above‐ and belowground ecosystem stability. It identifies arid regions as hotspots for this coupling and highlights temperature stability as a vital safeguard for maintaining ecosystem balance across our warming planet.

SPATIAL AND TEMPORAL DISTRIBUTION OF PHYTOPLANKTON IN LAKE GALA (Edirne/TURKEY)
Trakya University Journal of Natural Sciences, 2016 This study was performed from March 2004 to February 2005 in 4 stations in Gala Lake, a shallow lake located inside Gala Lake National Park in Meriç Delta. Water samples were taken from the lake in order to determine the phytoplankton present in the lake
