However, task complexity has emerged as a relevant component for both movement analysis and physical training, although it still lacks greater theoretical and empirical density. In this context, a training model known as Brain Functional Training (BFT) arises from the premise of increasing task complexity to enhance the activation of brain areas related to movement planning. Accordingly, this thesis investigated the effects and possible mechanisms of manipulating task complexity on the functionality of physically independent older women. In Study I, a theoretical framework was developed, based on a literature review, to support complexity as a variable of exercise dose. The hypothesis was that increasing complexity expands planning demands, elevates acute cognitive load, and more intensely recruits prefrontal regions associated with executive functions, thereby promoting functional adaptations when applied repeatedly. In Study II, the acute effects of different levels of complexity in a squat task were examined on markers of cognitive effort, physical performance, and executive performance in older women. An increase in cognitive effort was observed under more complex conditions, particularly when the squat task was combined with mental calculation or involved unilateral predominance. Despite the higher cognitive cost, no immediate differences were identified between conditions for executive performance. In contrast, increased complexity resulted in longer execution time, reduced movement velocity, and, when complexity was predominantly motor, reduced range of motion. Perceived exertion did not differ between conditions. In Study III, the effects of a 16-week intervention with BFT, functional training, and mind–body interventions were investigated, as well as retention after 16 weeks of detraining, on functionality, executive function, and body composition. All three models promoted similar improvements in functional and executive performance, with partial maintenance after detraining. BFT showed specific advantages in movement under dual-task conditions and inhibitory control, suggesting potential superiority in cognitive demands integrated with movement. All groups also increased appendicular lean mass post-intervention, with a partial decline during the detraining period. It is concluded that task complexity constitutes a promising variable of exercise dose, with acute effects on cognitive effort and motor performance, as well as relevant repeated effects on functionality and cognition in older women.

Among these gaps, the Hutchinsonian shortfall—related to the lack of knowledge about tolerance limits to abiotic factors—stands out as particularly relevant in the context of rapid climate change, since the absence of information on thermal tolerance compromises our understanding of species vulnerability, persistence, and future distributions. In this study, we investigated the magnitude of the Hutchinsonian shortfall associated with thermal biology traits of snakes, assessing the distribution and biases of available knowledge across geographic, phylogenetic, and climatic spaces. To this end, we integrated thermal biology data from the literature with spatial, phylogenetic, and environmental analyses. We compiled morphological, physiological, and climatic information from global databases and a systematic review, including data on thermal tolerance, evapotranspiration, and climatic niche under current conditions and future scenarios. Knowledge representativeness was evaluated using niche overlap tests, spatial autocorrelation analyses, and the phylogenetic aggregation index (NRI), in addition to analyses of changes in climatic conditions projected until 2100 under the SSP585 scenario. Our results demonstrate that knowledge of snake thermal biology is limited, strongly biased, and structured across phylogenetic, environmental, and geographic spaces, characterizing a multifaceted Hutchinsonian shortfall. Data are concentrated in a few clades and temperate regions, incompletely representing the group’s climatic niche, particularly for traits associated with minimum thermal tolerance and water balance. This pattern results in extensive portions of climatic space—especially in tropical regions—being systematically underrepresented. Projections of future climate scenarios indicate climatic rearrangements and the emergence of non-analog conditions, increasing uncertainty and limiting ecological inferences and realistic predictions about snake responses to global climate change.

This medical emergency primarily affects impoverished individuals living in rural communities, due to their high exposure to risk areas. Brazil is among the countries with the highest annual occurrence of snakebite cases. In the country, snake species of the Bothrops genus are responsible for most recorded accidents. In Chapter 1 of this dissertation, were employed spatial analyses to identify the determinants of Bothrops snakebite incidence in different regions of Brazil. Across the country, significantly higher snakebite incidence rates were observed in areas with higher percentages of native forest and historical forest loss. Additionally, we found that areas with higher temperatures and precipitation levels in the South, as well as higher climatic suitability for the B. jararaca species in the Southeast, exhibited significantly higher snakebite incidence rates. On the other hand, areas with higher percentages of pasture exhibited significantly lower snakebite incidence rates. In Chapter 2, we employed the Prophet time series model to develop snakebite incidence prediction models for each Brazilian region, considering the influence of covariates on predictive models. The Prophet model proved to be an effective tool in predicting snakebite incidence. We found that the Prophet model integrated with the covariate of maximum temperature in the South, forest fires in the North and Midwest, and a model without covariate integration in the Northeast and Southeast regions, demonstrated the best performance, indicating its potential application in epidemiological surveillance of this public health issue. Understanding the determinants and predicting snakebite incidence can help policymakers, public health authorities, and healthcare professionals develop and implement prevention and mitigation measures, thereby reducing the number of cases and associated adverse impacts.
