“…As for the climatic changes and extinction of species of anurans, we understand that the peculiar condition of Piauí, and the results found here, strengthen the basic principle of the plasticity of the species to the pressure conditions that the environment exerts and selects. Oliveira & Cassemiro (2013) corroborate our understanding when presenting studies on Rhinella granulosa, and according to the ecological model presented, the conditions of variation of prolonged droughts associated with the conspicuous condition of the species will not affect it until 2080 in case of global climate change.…”

The population fluctuations of amphibians were correlated with climatic changes, and among the aspects listed the global temperature change was one of the highlights. We submitted tadpoles of Pleurodema diplolister to aquatic thermal variations to establish the thermal limit that implies the direct influence of temperature on larval development, as could occur in the global temperature change. Natural lentic environments were monitored in a way to acquire the mean temperature of the water in an annual (tolerant) average (31°C) and in the reproduction (optimal) period (27°C) of the frogs. In lab conditions the tadpoles’ development were tested in four different temperatures: 20°C, 27°C, 31°C, and 40°C, corresponding to minimal, optimal, tolerant, and maximum temperatures, respectively. The survival time was established by the Kaplan-Meier method. The data were tested by the Chi-square test to establish the adherence of the results. The success rate calculated for 20°C temperature was 3.69%, at 27°C it was 62.33%, at 31°C it was 68% and at 40°C it was 1.35%. This demonstrates that there is an optimal temperature of larval development with a tolerance zone around it, which indicates that an increase in global temperature, immediately, will not stop the reproduction of this species.

This study estimated the potential effects of climate change on peripheral plant diversity by predicting the distribution of species from Cerrado of Northern Brazil. Ecological niche modeling was used to provide present and future projections of responses in terms of occurrence of ten woody species based on four algorithms and four future climate change scenarios for the year 2050. Potential refuge areas for conservation actions were identifi ed, and evidence of the vulnerability of the fl ora was demonstrated based on the disparity between potential areas of climate stability amid current protected areas. The results suggested a lack of pattern between the scenarios and an idiosyncratic response of the species, indicating different impacts on plant communities and the existence of unequal stable alternative conditions, which could bring consequences to the ecological relationships and functionality of the fl oras. Even in the most pessimistic scenarios, most species presented an expansion of potential occurrence areas, suppressing or cohabiting with species of adjacent biomes. Typically marginal plants were the most sensitive. Overlapping adequate habitats are concentrated in the NBC. The analysis of habitats in relation to anthropized areas and PAs demonstrate low future effectiveness in the protection of these savannas.

Objective: Climate change coupled with anthropogenic events can alter the distribution of biological groups and affect the reorganization, structure, dynamics and functioning of ecosystems and their services. Despite this, predictions of impacts on Brazilian savannas are scarce. This study estimated the potential effects of climate change on peripheral plant diversity by predicting the distribution of species from Cerrado. Site: Northern Brazilian Cerrado (NBC). Methods: Ecological niche modeling was used to provide present and future projections of responses in terms of occurrence of ten woody species based on four algorithms and four future climate change scenarios for the year 2050. Potential refuge areas for conservation actions were identified, and evidence of the vulnerability of the flora was demonstrated based on the disparity between potential areas of climate stability amid current protected areas (Conservation Units -CUs). Results: The results suggested a lack of pattern between the scenarios and an idiosyncratic response of the species, indicating different impacts on plant communities and the existence of unequal stable alternative conditions, which could bring consequences to the ecological relationships and functionality of the floras. Even in the most pessimistic scenarios, most species presented an expansion of potential occurrence areas, suppressing or cohabiting with species of adjacent biomes. Typically marginal plants were the most sensitive. Key findings: Overlapping adequate habitats are concentrated in the NBC. The analysis of habitats in relation to anthropized areas and CUs demonstrate low future effectiveness in the protection of these savannas, indicating the need to create CUs that consider the potential effects of climate change.
