The high minimum light requirement of eelgrass Zosfera marina L. suggests that this species has difficulty in maintaining a positive carbon balance except under high fight conditions. The carbon balance of Z. marina can be studied by following seasonal changes in non&ructural carbohydrate (NSC) reserves, however, little is known about the seasonal variation in NSC reserves in seagrasses or the ...

Improved understanding of the links between aboveground production and allocation of photosynthate to belowground processes and the temporal variation in those links is needed to interpret observations of belowground carbon cycling processes. Here, we show that combining a trenching manipulation with high-frequency soil respiration measurements in a temperate hardwood forest permitted identific...

In this paper we develop a canonical state space representation for rational stochastic processes containing unit roots with integer integration orders at arbitrary points on the unit circle. It is shown that the state space framework, which is – in a certain sense made precise in the paper – equivalent to the ARMA framework, is very suitable for the analysis of unit roots and cointegration iss...
