Intensive agriculture homogenizes landscape and reduces the proportion of natural habitats, thus altering wildlife ecology. In addition to landscape fragmentation, intensive agriculture is responsible for the release of chemicals into non-target environments, such as aquatic environments, which are particularly affected by this contamination. The transfer of these molecules to aquatic environments occurs though runoff or soil erosion. Pesticides can accumulate in large quantities in slow-flux habitats such as ponds and vernal-pools, potentially creating ecological traps for the species that inhabit them. Amphibians are sentinel species of their ecosystems and are particularly sensitive to agricultural chemicals, especially because of their particularly permeable skin. In addition, part of their complex (biphasic) life cycle takes place in lentic environments, which are likely to be highly contaminated. During my thesis, I studied the effects of agricultural activities on an amphibian species that is widespread in agricultural and forest environments, the spined toad (Bufo spinosus). To understand the consequences of agricultural activities on the ecology and physiology of this species, I studied the effects of habitat characteristics (structure and contamination) on different developmental stages (embryos, larvae, adults). To achieve these objectives, I used two methodological approaches: (i) a field approach to measure morphological and physiological differences of adult male populations in contrasting habitats; and, (ii) an experimental approach under controlled conditions to distinguish the effects of exposure period and concentration of different contaminants on key developmental phases of this species. The results indicate that male adult populations show different allometric relationships depending on the habitat (agricultural, intermediate or forest) and that these differences probably result from evolutionary mechanisms related to phenotypic plasticity. Indeed, preliminary population genetic analyses do not detect genetic divergence among the populations studied, suggesting that physical or chemical habitat characteristics result in different response norms among populations. The observed allometric relationships could be the result, at least in part, of developmental plasticity due to environmental contamination within breeding sites. Studies of exposure to two herbicides (a legacy contaminant metabolite and an emerging contaminant) over ontogeny in this species showed us that contamination results in variability in morphological (size and body proportion), physiological (oxidative stress) and behavioral responses that suggest that there may be endocrine disruption mechanisms operating at very low concentrations. In addition, contamination negatively influences fitness proxies in exposed individuals (size and mass at metamorphosis, survival) which could ultimately alter recruitment, reproduction and population sustainability of spined toads

In larval amphibians, predation risk assessment and adaptive anti-predator responses are tightly dependent on the detection of chemical signals released from predators and (or) injured conspecifics. However, such olfactory-mediated processes can be particularly vulnerable to the presence of waterborne chemical contaminants. Thus, the thesis aims to evaluate the behavioural, morphological and life-historical effects of single and combined embryo-larval exposures to a triazole herbicide (amitrole) and to different types of chemical signals indicative of a predation risk in the common frog (Rana temporaria) and the common toad (Bufo bufo). This experimental approach has resulted in a series of scientific articles, and the suggestion of some new research prospectives and measures relative to amphibians’ conservation
