Table 3. Selected published breakdown rates (k, d -1 ) for corn (Zea mays) and red maple (Acer rubrum) from surface and cave streams. Note that in Simon & Benfield’s (2001) study, breakdown rates were examined in caves streams that had either “direct” (i.e. upstream cave entrances or sinkholes) or “indirect” (i.e. small cracks and fissures) connections to surface environments.

Figure 1. (a) Box and whisker plot of organic matter (OM) abundance in four cave streams in northeastern Alabama and southeastern Tennessee, U.S.A. Grey boxes are the 25 th and 75 th percentile and whiskers are 5 th and 95 th percentiles. The dashed and solid lines within each box are the mean and median, respectively. Significant differences (P < 0.05) among caves are indicated by different letters. (b) Time series of OM abundance in each cave. Vertical dashed line separates incubation periods: left = incubation period 1 (Jan to Jul 2008), right = incubation period 2 (Jul to Dec 2008, or to Jan 2009 for Tony Sinks Cave). 4000 a d 3000 c 2000 -2 Standing crop OM (g AFDM m ) 1000 0 1600 1200 b a b Jess Elliot Salt River Big Mouth Tony Sinks Cave Big Mouth Jess Elliot Salt River Tony Sinks 800 400 0 J F M A M J J A S O N D J F Date 34
