Resumen:
Before a population becomes extinct, there are hidden costs in the
physiology at the individual level that provide valuable insights into
their condition. Here, we study two dams with one species in common
(Argia anceps Garrison, 1996) to evaluate whether their physiological
condition differed (total protein quantity, prophenoloxidase (proPO) and
phenoloxidase (PO) activity, and protein carbonylation) during two
consecutive years. The first dam, ``El Gallinero'' (contaminated, C),
contains organic input from mines and agricultural activity, whereas the
second, ``Paso de Vaqueros'' (non-contaminated, NC), is part of a
biosphere reserve. Although at a phenological level, some physiological
differences were observed (2012 vs 2013), individuals from the
contaminated population had less total protein (2012, median = 1.815 mu
g/mu L; 2013, 0.081 mu g/mu L) and more carbonylations in their proteins
(2012, median = 19.00 nmol/mg; 2013, median = 121.69 nmol/mg) compared
with the non-contaminated population (protein quantity in 2012, median =
3.716 mu g/mu L; 2013, median = 0.054 mu g/mu L; protein carbonylations
in 2012, median = 0.00 nmol/mg; 2013, median = 99.44 nmol/mg). However,
no significant differences were found in prophenoloxidase (C, median =
0.002 Vmax; NC, median = 0.002 Vmax) and phenoloxidase activity (C,
median = 0.002 Vmax; NC, median = 0.001 Vmax). In addition, the
biological oxygen demand (BOD) and Zn were more elevated in the C than
NC population (C, BOD = 11.7, Zn = 0.17; NC, BOD = 8, Zn = 0.14). The
results show that the impact of human activity can be observed not only
through the extinction of species, but also at the physiological level
of the individuals composing the populations through the evaluation of
biomolecular damage, which can be observed at a much shorter scale
compared with species extinction.
