Transient Flooding and Soil Covering Interfere with Decomposition Dynamics of Populus euphratica Leaf Litter: Changes of Mass Loss and Stoichiometry of C, N, P, and K

چکیده

Litter decomposition plays a critical role in carbon and nutrient cycling terrestrial aquatic ecosystems. However, the effects transient flooding soil covering have on leaf litter remain unclear. The changes of mass loss stoichiometric ratio C:N (the to nitrogen), C:K potassium), C:P phosphorus), N:P nitrogen N:K potassium) fresh Populus euphratica (P. euphratica) leaves surface, flooding, treatments were studied using litterbags desert riparian forest field experiment for period 640 d. results showed that there was significant influence disturbance type incubation time rate ratios C:N, C:K, C:P, N:P, P. leaves, but no interaction between loss. In three treatments, five sequential phases different temporal change patterns identified within Transient shown affect compared no-disturbance conditions, especially promote 0–173 d time. It also demonstrated can decomposition, which led exhibiting varied during decay.

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
