Effects of a mining‐altered environment on individual fitness of amphibians and reptiles

Abstract: Pollution can affect wildlife directly through toxicity and indirectly through changes in biotic and abiotic factors, however, how these mechanisms interact in affecting free‐ranging animals remains poorly understood. By examining effects on individual fitness proxies, we aimed to determine the mechanisms behind documented amphibian and reptile declines in barren landscapes where vegetation was nearly decimated due to atmospheric metal and sulfur deposition from smelting operations in Sudbury, Ontario, Canada.… Show more

“…One of the most critical issues in mine environments is the natural oxidation (chemical and biological) of sulfide mineral tailings that are exposed to water, oxygen, and microorganisms. This oxidation is responsible for the generation of mine drainage that compromises the quality of soil, surface water, and sub-surface water bodies, hence affecting overall biodiversity [2][3][4][5].…”

“…These deposits are permanent source of toxic substances, especially heavy metals which contaminate all environmental compounds, mainly soil and water. Changes of water and soil quality affect also biodiversity of mining area [2][3][4][5]. The properties of drainage water depend on many factors, including mineralogical, geochemical properties, hydrogeological conditions, and the activity of lithoautotrophic microorganisms.…”

“…All three life history traits (growth rate, reproductive output, and survivorship), usually used as a measure of habitat quality, are dependent to varying degrees on an animal's BC (Shine et al, 2001;Litzgus et al, 2008;Harrison et al, 2011;Gallego-Carmona et al, 2016;Sasaki et al, 2016) which in turn reflects the availability of energy, in terms of food/prey abundance and quality, within the habitat. Our study shows that the BC of heathland snakes remained relatively constant whilst that of plantation snakes, which was initially similar to that of heathland snakes, declined with increasing plantation age and was negatively correlated with increasing tree canopy cover.…”

“…In addition, most studies that have compared a species performance within different habitat types have done so in those habitats that are relatively stable (e.g. Morris, 1989;Mosser et al, 2009;Sasaki et al, 2016;Allen et al, 2017) whilst fewer have attempted to do so where at least one of the habitat types under investigation is transient (Welsh et al, 2008;Rotem et al 2013).…”

“…Nonetheless, sublethal effects of environmental pollutants on individuals can reduce their fitness, leading to population-level impacts (e.g., Kidd et al 2007;Incardona et al 2015). Notably, pollutants not only have direct toxic effects on organisms, but may also potentially cause harm through indirect pathways (e.g., trophic cascades; Kidd et al 2014;Sasaki et al 2016). Pollution can also compound the effects of other drivers of decline, weakening populations already affected by loss of habitat, overexploitation, or other threats (Brook et al 2008;Darling and Côté 2008).…”
