“…In addition, it may be due to the insufficient detoxification capacity of FPN and damage caused by reactive oxygen species. FPN reduced the activity of GST and GPx in tadpoles of frogs [60] . Similar significant decreased in GST activity were observed in the liver of chlorpyrifos treated rats [17] .…”

“…GST constitute a family of enzymes that play an important role in metabolism, particularly in detoxification of xenobiotic e.g. pesticides and intracellular transport of metabolites [60] . These enzymes catalyze the conjugation of reactive electrophiles with glutathione (GSH), and have been implicated with the potential of forming reactive intermediates in particular when GSH levels in the cells are attenuated, consequently resulting in toxicological effects [61] , [62] .…”

“…The number of literature reviewed which deals with the impact of sugarcane production on biodiversity (18 references), confirms what has been mentioned about the absence of attention for this kind of research. Literature that has been assessed focused mainly on species richness in soils and waters such as fish, earthworms, termites, ants, preys, spiders and amphibians (Santos et al, 2018;Zeni et al, 2017;Stefani Margarido et al, 2013;Dlamini and Haynes, 2004;Miranda et al, 2004;Haynes et al, 2003;Zou and Bashkin, 1998;Ali et al, 1986) and results showed a reduction in these communities between sugarcane and other land uses. They also noted a difference in the number of these communities between different management practices within sugarcane fields.…”

Since the 1950s sugarcane production has grown rapidly from less than 0.5 billion tonnes in the late 50s to reach over 1.9 billion tonnes in 2012 on about 27 million hectares of agricultural land. This expansion has been boosted by the high demand for bioethanol promoted as a sustainable bioenergy source which accounted in 2010 for the biggest share of the global biofuel market. Despite its benefits, the scientific debate on sugar is growing especially that counterarguments are so many, including negative impacts on different interacting ecosystems and human well-being, e.g. bigger stress on land and water resources, environmental externalities on air, a harmful impact on the biodiversity and endemic species, negative environmental externalities, health, and socio-economic aspects. This paper provides a narrative systematic review (SR) of the impacts of sugarcane production on these different ecosystems employing the ecosystem services framework for its acceptance by policy-makers. The references included for the SR were 163 and results showed that the majority of the studies are from Brazil, Australia, South Africa and the USA (≈ 75% of the literature), most of them were from peer-reviewed journals (85%), and most of the case studies adopted a quantitative research approach (93%). The literature assessed showed that sugarcane, like all agro-systems, depends on the practices and techniques to transform negative impacts into positive externalities on ecosystems and human well-being. However, the literature studied failed to include the inter-linkage in sugarcane production impacts’ and therefore to evaluate the related ecosystem services with respect to the Millennium Ecosystem Assessment (MA) framework to account for existing trade-offs. Therefore, the findings are addressed to the scientific community and decision-maker for an intensification of interdisciplinary and integrated research based on the MA framework to cover all ecosystem services, for sustainable development of the sugarcane sector.

“…Environmental contaminants can lead organisms to oxidative stress, a condition that is also triggered by increases of temperature Gripp et al, 2017;Madeira et al, 2013;Stefani Margarido et al, 2013;Vinagre et al, 2012). Studies have indicated that changes on environmental temperature can alter physiological stress response in aquatic organisms, and that ROS production is usually increased at higher temperatures as a consequence of an increased metabolism which leads to higher oxygen consumption .…”

Temperature is an important factor influencing the toxicity of chemicals in aquatic environments. Neotropical tadpoles experience large temperature fluctuations in their habitats and many species are distributed in areas impacted by agriculture. This study evaluated the effects caused by the exposure to clomazone (Gamit) at different temperatures (28, 32 and 36 °C) on biochemical stress responses and esterase activities in Physalaemus nattereri and Rhinella schneideri tadpoles. Results evidenced that temperature modulates the effects of clomazone on biochemical response of tadpoles. Antioxidant enzymes, including catalase, superoxide dismutase (SOD), and glucose-6-phosphate dehydrogenase had their activities increased by clomazone in P. nattereri treated at higher temperatures. The biotransformation enzyme glutathione-S-transferase (GST) was also induced by clomazone at 32 and 36 °C. In R. schneideri, clomazone failed to alter antioxidant enzymes at 28 °C, but SOD and GST were increased by clomazone at higher temperatures after three days. All enzymes had their activities returned to the control levels after eight days in R. schneideri. Lipid peroxidation was induced in both species exposed to clomazone at 32 and 36 °C, but not at 28 °C. Acetylcholinesterase was not sensitive to clomazone and temperature, while most treatments impaired carboxylesterase activity. Integrated biomarker response (IBR) was notably induced by temperature in both species, and a synergic effect of temperature and clomazone was mostly observed after three days of exposure. These findings imply that tadpoles from tropical areas may present differential responses in their physiological mechanism linked to antioxidant defense to deal with temperature fluctuations and agrochemicals presence in their habitats.
