Remotely-sensed slowing down in spatially patterned dryland ecosystems by Veldhuis, M.P., Martínez Garcia, R., Deblauwe, V., Dakos, V.

“…Model simulations reveal that the transition between patterns temporarily slows down the system affecting the temporal indicators. These transient states when vegetation patterns reorganize thus affect the systems resilience indicators in a non-linear way. …”

Effect of supplementation with groundnut cake and phosphorus on utilisation of millet stover by sheep and excretion of nutrients by Sangare, M., Fernández Rivera, S., Hiernaux, Pierre H.Y., Pandey, V.S.

“…Millet stover intake (g kg-1 LW) was related to GC level by both linear (+1.79 (+ or -) 0.53 g per g GC) and quadratic (-0.20 (+ or -) 0.07 g per g GC2) functions and to P supplementation by linear function (0.87 (+ or -) 0.46 g per g P). …”

Ammonium fluxes into plant roots: Energetics, kinetics and regulation by Glass, Anthony D. M., Erner, Yair, Kronzucker, Herbert J., Schjoerring, Jan K., Siddiqi, M. Yaeesh, Wang, M.-Yuan

“…Kinetic studies using 13NH4+ established that influx at low external [H4+] occurred via high affinity transport systems (HATS) in rice and spruce, while at higher [NH4+], influx was mediated by low affinity transport systems (LATS), that showed linear concentration dependence. …”

Economic opportunities for smallholders to combine pulpwood trees and food crops by Menz, K.M., Grist, P.

“…The modelling framework was conventional linear programming. The interplay of land area availability, land and labour productivity, and interest rates lead to a relatively complex picture, even for the simplified farming systems that were examined. …”
