Abstract

What is the value of long-term ecological research (LTER) for young academic (or professional) ecologists? In this review, we suggest that combining long-term and large-scale monitoring, which are primary components of LTER, with field experiments allows for effective hypothesis testing in the field. The procedure is as follows: first, long-term and large-scale studies detect new spatial and temporal patterns in ecological processes. Consequently, new hypotheses can be formulated. Finally, field experiments can test these hypotheses by isolating and manipulating the driving factors. This process is very useful because it provides a means of first searching for, and ultimately elucidating the mechanisms underlying, a new subject. To this end, it is also important to connect with other researchers across multiple disciplines. Freeing oneself from private management may also pave the way to new research topics of interest to young ecologists.
