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 μg/μL; 2013, 0.081 μg/μL) 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 μg/μL; 2013, median = 0.054 μg/μL; 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.

污染造成的Argia anceps(Zigoptera:Coenagrionidae)生理隐性成本

在种群灭绝之前,个体层面的生理隐性成本为他们的状况提供了宝贵的见识。在这里,我们研究了两个具有共同物种的水坝(Argia ancepsGarrison,1996年),以评估他们在连续两年中的生理状况是否有所不同(总蛋白量,前酚氧化酶(proPO)和酚氧化酶(PO)活性以及蛋白羰基化)。第一个大坝“ El Gallinero”(受污染,C)包含来自矿山和农业活动的有机投入,而第二个大坝“ Paso de Vaqueros”(未污染,北卡罗来纳州)是生物圈保护区的一部分。尽管在物候水平上观察到了一些生理差异(2012年与2013年),但受污染人群的个体总蛋白较少(2012年,中位数= 1.815μg/μL; 2013年为0.081μg/μL),并且蛋白质中的羰基化程度更高( 2012年,中位数= 19.00 nmol / mg; 2013年,中位数= 121.69 nmol / mg),与未污染人群相比(2012年蛋白质含量,中位数= 3.716μg/μL; 2013年,中位数= 0.054μg/μL; 2012年蛋白质羰基化,中位数= 0.00 nmol / mg; 2013,中位数= 99.44 nmol / mg)。但是,前酚氧化酶(C,中位数= 0.002 Vmax; NC,中位数= 0.002 Vmax)和酚氧化酶活性(C,中位数= 0.002 Vmax; NC,中位数= 0.001 Vmax)没有发现显着差异。此外,碳中的生物需氧量(BOD)和锌比NC人群更高(C,BOD = 11.7,Zn = 0.17; NC,BOD = 8,Zn = 0.14)。结果表明,不仅可以通过物种灭绝来观察人类活动的影响,还可以通过评估生物分子的破坏来观察组成种群的个体的生理水平,与之相比,可以观察到更短的尺度。物种灭绝。在酚氧化酶原(C,中位数= 0.002 Vmax; NC,中位数= 0.002 Vmax)和酚氧化酶活性(C,中位数= 0.002 Vmax; NC,中位数= 0.001 Vmax)方面没有发现显着差异。此外,碳中的生物需氧量(BOD)和锌比NC人群更高(C,BOD = 11.7,Zn = 0.17; NC,BOD = 8,Zn = 0.14)。结果表明,不仅可以通过物种灭绝来观察人类活动的影响,还可以通过评估生物分子的破坏来观察组成种群的个体的生理水平,与之相比,可以观察到更短的尺度。物种灭绝。在酚氧化酶原(C,中位数= 0.002 Vmax; NC,中位数= 0.002 Vmax)和酚氧化酶活性(C,中位数= 0.002 Vmax; NC,中位数= 0.001 Vmax)方面没有发现显着差异。此外,碳中的生物需氧量(BOD)和锌比NC人群更高(C,BOD = 11.7,Zn = 0.17; NC,BOD = 8,Zn = 0.14)。结果表明,不仅可以通过物种灭绝来观察人类活动的影响,还可以通过评估生物分子的破坏来观察组成种群的个体的生理水平,与之相比,可以观察到更短的尺度。物种灭绝。C区的生物需氧量(BOD)和Zn含量均高于NC人群(C,BOD = 11.7,Zn = 0.17; NC,BOD = 8,Zn = 0.14)。结果表明,不仅可以通过物种灭绝来观察人类活动的影响,还可以通过评估生物分子的破坏来观察组成种群的个体的生理水平,与之相比,可以观察到更短的尺度。物种灭绝。C区的生物需氧量(BOD)和Zn含量均高于NC人群(C,BOD = 11.7,Zn = 0.17; NC,BOD = 8,Zn = 0.14)。结果表明,不仅可以通过物种灭绝来观察人类活动的影响,还可以通过评估生物分子的破坏来观察组成种群的个体的生理水平,与之相比,可以观察到更短的尺度。物种灭绝。
