Soil respiration is the result of heterotrophic respiration (Rh) and autotrophic respiration (Ra), accounting for about 50%–75% of the total ecosystem respiration on land, which is crucial for the global carbon cycle and plays an indispensable role in biogeochemical models. With increasing global warming, understanding the response of forest soil Rh and Ra to warming…
Sweet flavors and healthy ingredients make strawberries one of the world’s most popular berries. The complex biochemical compounds that determine the flavor and nutritional value of a strawberry—known as biomarkers—can only be determined in detail by experts using modern analyses. Sweet flavors and healthy ingredients make strawberries one of the world’s most popular berries. The complex…
