Species that exhibit broad ranges of distribution may successfully
navigate environmental changes by modifying some of their life history
traits. Environmental humidity imposes a critical stress that organisms
may overcome by increasing their resistance to desiccation. We used
experimental evolution to investigate adaptation to desiccation in the
tephritid Anastrepha ludens, a species with high fecundity, late
maturation and long lifespan. We measured morphological, physiological,
developmental as well as demographic changes involved in the adaptation to
desiccation. Notwithstanding a low heritability (h2 = 0.237), desiccation
resistance evolved extremely rapidly and few negative trade-offs were
detected. Selected flies exhibited correlated increases in longevity, body
size, the amount of body lipids and bulk water content, and in the
duration of the pupal stage. Females further delayed sexual maturation,
decreased daily fecundity but retained high lifetime reproductive
potential. No differences in male mating competitiveness were found.
Selected and control lines differed in longevity but not in total female
fecundity, demonstrating that A. ludens flies have the capability for fast
adaptation to desiccation without loosing their reproductive capability.
Thus, it seems that a rapid evolutionary response to desiccation in this
polyphagous insect works as a buffer for environmental variation and
reduces the strength of selection on reproductive traits.
Response to selectionSheet 1: Raw data of survival and their phenotypic
variance (standard deviation) for each population, sex, generation
combination. Sheet 2: model fitted to test for response to selection, note
that we nest generation in treatment. Sheet 3: mean survival for each
population and generation combination, Grand means for each treatment for
each generation, as presented in Fig 1 and supplementary table 1.
"Parental" represent the survivial data of moscafut mass reared
strain tested at F7 (not included on the model).HeritabilitySheet 1: Raw
data of resistance, selection intensities and response to selection by
sex. Sheet 2: Final data based on a population level (mean intensity on
population) and the estimated response for each selection event. Final
variables are "selection cumulative" and "response
cumulative". Note that response are corrected by mean control
resistance on each generation. Sheet 3: Using the data on sheet 2 , we
present the full model to asses the heritabilitty. Note that model are
fixed to the origin (no selection have no response).Demography - life
tablesSheet 1: Raw data of demography (dialy survival and fecundity) for
each population (C1-C5, D1-D5). Sheet 2-11: demography and estimated
demography parameters for each population. Sheet 12 Mean of estimated
parameters by treatment. Sheet 13-14: pool demography by treatment. Sheet
15 : Cumulative survival and reproduction by treatment as presented on
figure 3.transition matricesSheet 1: transition matrices for each
population. symbols: p= survival (transition) ; f= fecundity ; C= control
population; D= desiccation or selected population; 1-5= number of replica
population. Note: see Rockwood 2006 to see details of construction of Px
and Fx from a life table. Life tables of each population are presented on
a separated file. For LTRE analysis, mean transition matrices per
treatment was used. See "popbio" library of R for details of
LTRE analysis and lambda estimation.Size water and lipidsFor the analysis
of Size, water and lipids contain on selected and control treatments the
raw data and the data for each population are presented. Sheet 1: Raw data
for each fly, on desing we proyected 15 fly per sex of each population.
Sheet 2: Data of each population by sex, was constructed using mean of
individual values. Full factorial was used to analyzed the response to
selection.Pupal stage durationWe present the duration of pupal stage, in
hrs, of individuals flies for each population and replica. Sheet 1: Raw
data of time to emerge of each fly. Sheet 2: parametric survival model of
time to emerge and the estimated time were 50% of the flies had emerged
from the pupa. Note that some factors are nested and data are presented
per replica. Sheet 3: estimated mean time to emerge by replica, then, mean
of replicas by population and, then, mean of populations to obtain
treatment means.Sexual CompetitivenessSheet1: we present the frequency of
copulas per treatment for each of the 18 field cages. Sheet 2: Analysis :
chi squared test for competitiveness between selected and control
males.Sexual competitiveness.xlsx
