由于流域是一个复杂的系统，很难直接研究，因此经常对排放它们的河流进行采样，以寻找流域的信号。“这些信号包括同位素的存在和/或丰度、沉积物的类型、生物体（包括病原体），与短暂的生物地球化学过程或人为影响有关的化合物，等等。就像流域可以通过从中流出的溪流发送信号一样，我们提出了一个概念性的分析，（同样复杂和难以研究的系统）可能通过其茎干的降水（茎流）发送类似的信号。对于大，高，难以进入的树冠，这部分降水可能是适度的，往往
As watersheds are complex systems that are difficult to directly study, the streams that drain them are often sampled to search for watershed "signals." These signals include the presence and/or abundance of isotopes, types of sediment, organisms (including pathogens), chemical compounds associated with ephemeral biogeochemical processes or anthropogenic impacts, and so on. Just like watersheds can send signals via the streams that drain from them, we present a conceptual analysis that suggests plant canopies (equally complex and hard-to-study systems) may send similar signals via the precipitation that drains down their stems (stemflow). For large, tall, hard-to-access tree canopies, this portion of precipitation may be modest, often
