1. Bottom trawling is the most widespread human activity directly
affecting seabed habitats. Assessment and effective management of the
effects of bottom trawling at the scale of fisheries requires an
understanding of differences in sensitivity of biota to trawling.
Responses to disturbance are expected to depend on the intrinsic rate of
increase of populations (r), which is expected to be linearly related to
the reciprocal of longevity. 2. We examine the relationship between the
longevity of benthic invertebrates and their response to bottom trawling;
both in terms of the immediate mortality following a trawl pass and their
subsequent rates of recovery. We collate all available data from
experimental and comparative trawling studies, and test how longevity
influences these aspects of sensitivity. 3. The shortest-lived organisms
(<1yr) increased in abundance shortly after experimental trawling,
but showed no response to trawling in longer-term comparative studies.
Conversely, the abundance of biota with a life-span >1yr decreased
by ~9% immediately following a trawl pass. The effect of bottom trawling
in comparative studies increased with longevity, with a 2-3× larger effect
on biota living >10yr than on biota living 1-3yr. We attribute this
difference to the slower recovery rates of the longer-lived biota. 4. The
observed relationship between the intrinsic rate of population increase
(r, our metric of recovery rate) and the reciprocal of longevity matches
theoretical expectation and predicts that the sensitivity of habitats to
bottom trawling is higher in habitats with higher proportions of
long-lived organisms. 5. Synthesis and Applications. Where the longevity
of a species or the longevity distribution of a community is known or can
be inferred, our estimates of depletion and intrinsic rate of increase can
be combined with high-resolution maps of trawling intensity to assess
trawling impacts at the scale of the fishery or other defined unit of
assessment. Our estimates of r may also be used to estimate recovery times
following other forms of seabed disturbance.06-Sep-2018
