Article Synopsis
- Lignin, a complex plant polymer, influences litter decomposition rates but doesn't always majorly affect soil organic carbon (SOC) levels, indicating a need to consider different soil characteristics.
- Research across various North American soils shows that lignin decomposition varies significantly and is closely tied to litter decomposition, while SOC decomposition is affected differently.
- Factors like climate legacy and metal presence play critical roles in lignin decomposition, while SOC decomposition is less influenced by these factors, suggesting that lignin's role in SOC dynamics can differ across ecosystems.
Adrenoceptor and local modulator control of cutaneous blood flow in thermal stress.

March 2002
Blood flow to the skin is controlled by body temperatures in two ways: core and mean skin temperature combine in the central nervous system to form a reflex mechanism that controls the frequency of activity in sympathetic nerves to the cutaneous blood vessels; and local mechanisms independent of reflex effects control contractile response to the sympathetic transmitter norepinephrine (NE) at different temperatures. Cutaneous vessels differ in responsiveness to NE across temperatures: in limbs and tails, the superficial vessels constrict more strongly to NE when cooled, while the deep vessels show weaker responses to NE when cooled. This allows the limb to dissipate heat when warm and to conserve heat when cool.
