“…Th eir causes are not diffi cult to determine, because the indicated pathologies are well studied in the context of medicine. Th ese results do not contradict the data of other authors (Loumbourdis, 2007;Falushinnska et al, 2008). At the same time a specifi c complex of histological changes in the frog liver parenchyma were described too.…”

Histological Changes in Common Toad, Bufo Bufo (Anura, Bufonidae), Liver Tissue Under Conditions of Anthropogenically Transformed Ecosystems

In the article the histological changes in the liver of the common toad, Bufo bufo (Linnaeus, 1758), under conditions of moderate anthropogenic pollution (a vast park surrounded by urban areas) are examined. In the liver parenchyma, numerous changes characteristic of toxic damage were found: hepatocyte necrosis, fatty dystrophy, protein (and hydropic) dystrophy, signs of infl ammation. An analysis of the number of pigment inclusions in the liver shows hyperpigmentation in some specimens and hypopigmentation in others. The presence of hyperpigmentation indicates a moderate degree of damage and activation of compensation processes in animals. This is confirmed by a large population of common toads in this biotope. It is concluded that in anthropogenically modified biotopes some deterioration of animal health can be compensated by the absence of predators and the reduction of food competition.

“…Studies on Amphibia Anura [78,79,81,82,125] and in particular on Ranidae, the Italian pool frog Pelophylax bergeri, showed how temperature fluctuations and pollutants can affect the antioxidant defense [123,126]. In fact, a large study (2011-2016) carried out along the coasts of Sarno (Italy) highlighted how a contaminated site produces radical content in Pelophylax bergeri skin tissues.…”

The objective of this review is to briefly summarize the recent progress in studies done on the assessment of reprotoxicity risk posed by global warming for the foundation of strategic tool in ecosystem-based adaptation. The selected animal data analysis that was used in this paper focuses on antioxidative markers and fertility rate estimated over the period 2000–2019. We followed a phylogenetic methodology in order to report data on a panel of selected organisms that show dangerous effects. The oxidative damage studies related to temperature fluctuation occurring in biosentinels of different invertebrate and vertebrate classes show a consistently maintained physiological defense. Furthermore, the results from homeothermic and poikilothermic species in our study highlight the influence of temperature rise on reprotoxicity.

“…However, the field is rapidly growing, and knowledge about other species, taxonomic groups and their physiological responses in different geographical and climatic regions is increasing (e.g. French et al, 2008;Falfushinska, et al, 2008aFalfushinska, et al, , 2018bRadwan et al, 2010;Payne et al, 2012).…”

Urban ecophysiology: beyond costs, stress and biomarkers

Natural habitats are rapidly declining due to urbanisation, with a concomitant decline in biodiversity in highly urbanised areas. Yet thousands of different species have colonised urban environments. These organisms are exposed to novel urban conditions, which are sometimes beneficial, but most often challenging, such as increased ambient temperature, chemicals, noise and light pollution, dietary alterations and disturbance by humans. Given the fundamental role of physiological responses in coping with such conditions, certain physiological systems such as the redox system, metabolism and hormones are thought to specifically influence organisms’ ability to persist and cope with urbanisation. However, these physiological systems often show mixed responses to urbanisation. Does this mean that some individuals, populations or species are resilient to the urban environmental challenges? Or is something missing from our analyses, leading us to erroneous conclusions regarding the impact of urbanisation? To understand the impact of urbanisation, I argue that a more integrated mechanistic and ecological approach is needed, along with experiments, in order to fully understand the physiological responses; without knowledge of their ecological and evolutionary context, physiological measures alone can be misinterpreted. Furthermore, we need to further investigate the causes of and capacity for individual plasticity in order to understand not only the impact of urbanisation, but also species resilience. I argue that abiotic and biotic urban factors can interact (e.g. pollution with micro- and macronutrients) to either constrain or relax individual physiological responses – and, thereby, plasticity – on a temporal and/or spatial scale, which can lead to erroneous conclusions regarding the impact of urbanisation.
