II. The PPT–ANPP relationships: spatial against temporary habits
Analytical matchmaking to own spatial patterns usually are nonlinear (concave down otherwise saturating, Fig
The newest PPT–ANPP matchmaking is normally produced by multi-seasons sized PPT and you can ANPP, which can be viewed due to both a beneficial spatial or temporal contact. It’s got led to a couple of type of patterns: spatial models centered on ANPP investigation shared away from of many websites arrayed collectively PPT gradients, and you can temporal patterns based on private internet in which PPT and ANPP keeps ranged over time (Fig. 1). These patterns are associated given that spatial patterns are centered on imply values out-of web site-based temporal patterns (Huxman mais aussi al., 2004 ). 1) after they span higher gradients inside the PPT, regardless of if these can getting linear when activities was limited to a good single biome (Fig. 1, elizabeth.g. grasslands – Sala et al., 2012 ). Temporary PPT–ANPP relationship out of much time-term website-peak studies are nearly always illustrated as the linear whatever the environment type of (Fig. 1). (περισσότερα…)
