Increased climate variability as a result of anthropogenic climate change
can threaten the functioning of ecosystem services. However, diverse
responses to climate change among species (response diversity) can provide
ecosystems with resilience to this growing threat. Measuring and managing
response diversity and resilience to global change are key ecological
challenges. Here, we develop a novel index of climate resilience of
ecosystem services, exemplified by calculating the thermal resilience of
predator communities providing biological pest control. Field assays
revealed substantial differences in temperature-dependent activity of
predator species. Based on this information, our index revealed higher
thermal resilience in predator communities of high response diversity and
functional evenness (equity in service provisioning). Predator assemblages
with higher thermal resilience provided more stable pest control in
microcosms where temperature was experimentally varied, confirming that
the index of thermal resilience developed here is linked to predator
function. Importantly, complex landscapes containing a high number of
non-crop habitat patches were more likely to contain predator communities
with high thermal resilience. Thus, the conservation and restoration of
non-crop habitats in agricultural landscapes – practices known to
strengthen natural pest suppression under current conditions – will also
confer resilience in ecosystem service provisioning within a changing
climate.
Data obtained from field trapping for ground-dwelling arthropod predators
in spring barley fields surrouding the city of Uppsala, south-central
Sweden. Field trapping for temperature niche calculations was conducted
over five consecutive weeks in the months of June and July 2017 with
sampling occasions one day per week over a total period of five weeks.
During each day of sampling, traps were open for one 2-hour period in the
morning (10:00 -12:00) and one 2-hour period in the afternoon (13:00
-15:00), emptied immediately after each 2-hour period and kept closed
before and after sampling sessions. Miniature temperature loggers (SL54TH,
Signatrol, Tewkesbury, United Kingdom) were used to monitor ambient
temperature during the surveys. Each logger was located approx. 2 cm above
the soil surface and protected from direct sunlight by a plastic tray
located an additional 5 cm above the logger. For each transect and
sampling session, the average of temperature readings of the six loggers
was calculated and used as ambient temperature for the subsequent analysis
of predator-specific temperature niches. The data set contains the number
of individual predators collected at the respective temperature. Field
trapping for activity densities for the landscape analysis was conducted
over five consecutive weeks in the months of May and June in 2011. Traps
were open for the entire sampling period and emptied weekly.
