The capacity to tolerate climate change often varies across ontogeny in
organisms with complex life cycles. Recently developed species
distribution models incorporate traits across life stages; however, these
life-cycle models primarily evaluate effects of lethal change. Here, we
examine impacts of recurrent sublethal warming on development and survival
in ecological projections of climate change. We reared lizard embryos in
the laboratory under temperature cycles that simulated contemporary
conditions and warming scenarios. We also artificially warmed natural
nests to mimic laboratory treatments. In both cases, recurrent sublethal
warming decreased embryonic survival and hatchling sizes. Incorporating
survivorship results into a mechanistic species distribution model reduced
annual survival by up to 24% compared to models that did not incorporate
sublethal warming. Contrary to models without sublethal effects, our model
suggests that modest increases in developmental temperatures influence
species ranges due to effects on survivorship.
output from 'lethal' and 'sublethal' modelsThis Zip
archive contains 14 netCDF files with the output from the lethal,
sublethal, and age-at-maturity models. All file names indicate the time
period ['contemp' = 1980-2000; 'future' = 2080-2100],
variables ([survival' = embryo survival (percent decimal)
'growth' = population growth (lizards/year),
'maturity' = age at maturity (days), 'minmaxtemp' =
minimum and maximum daily temperatures(°C)], and whether the output is
from the 'lethal' or 'sublethal' model as described in
the manuscript (or in the case of the age-at-maturity model, whether it
includes the effect of slowed juvenile
growth).Carloetal_EcolLett_model_output.zipCarloetal_EcolLett_labandfield_rearing_data2014and2015This .csv file contains data from the laboratory and field experiments described in the manuscript, including embryonic mortality and development times, maximum daily temperatures, hatchling sizes and body conditions, and juvenile growth rates estimated from von Bertalanffy growth models (for a subset of laboratory-reared lizards).
