The selection of native forage species with yield potential under climate change scenarios can strengthen resilience of the Brazilian semiarid region. This study aimed to evaluate the effect of increasing temperature on growth and morphological and yield responses of plants of the genus Manihot. The experimental design was completely randomized in a 2×9 factorial arrangement (two temperature regimes and nine genotypes). The increase in temperature promoted higher plant dry mass (PDM) for genotypes A:24, A:79, A:102, A:EL, and A:GO during establishment. The percentage of leaves was reduced with the highest temperatures in the establishment, except for genotypes A:20, A:21, and A:GO. The increase in temperature during regrowth increased leaf dry mass (LDM) and reduced the leaf to stem ratio, except for A:24, A:79, and A:102, which presented similar values at both temperatures. Species of the genus Manihot respond differently to the 4.8 °C increase in air temperature. The increase in temperature shows a positive impact on the biomass production of species of this genus.

An increase in the carbon dioxide concentration (CO2) in the atmosphere has occurred in recent years, influencing the different biological aspects of herbivorous insects. The present study aimed to evaluate the effect of CO2 increase on the biological aspects of Liriomyza sativae Blanchard leafminer in melon plants. For this, two experiments were carried out: (i) to evaluate the effect of melon plants grown in CO2-enriched environments on the immature developmental stages of L. sativae and L. sativae adult longevity, and (ii) to verify the impact of increased CO2 concentration on L. sativae adult survival, feeding punctures, and oviposition. The experiments were carried out in growth chambers maintained in the temperature regime of 20-26-33 °C (simulating the minimum, average, and maximum daily temperature) and under two CO2 concentrations (400 ppm and 770 ppm). The immature stages and the egg-adult period of L. sativae were longer when they developed on plants grown in high CO2 levels (770 ppm), but no difference in adult longevity was observed. The viability of the immature phases was not different between the two CO2 concentrations. Furthermore, there was no difference in the number of eggs and feeding punctures between treatments. Thus, the increase in CO2 concentration prolongs the duration of the immature stages of L. sativae; however, it does not affect their viability. Adult survival, fertility, and feeding punctures were also unmodified by the environment enriched with CO2.

1000 khz, consecutively. Fat free mass (FFM), fat mass (FM) of the participants were assessed. Results: In the young population, there were no significant differences between analyses obtained from the single-and multi-frequency BIA devices, in terms of FFM, FM. However, in the older adults' group, results obtained from the single-frequency BIA device differed significantly from the multi-frequency one. Fat mass analyzed by single-frequency BIA device was significantly lower than measured by multi-frequency device. In contrast, fat-free mass measured by single frequency device was significantly higher compared to analyses obtained from multi-frequency BIA device (Table 1). Conclusion: Body composition analyses might significantly vary in older adults depending on the device used. Therefore, modality of the device used, i.e. single-or multi-frequency BIA, might influence sarcopenia categorization of an older adult. Absence of differences between devices in young adults suggest that age-related changes might be responsible for obtaining different Results depending on the modality. Further studies are needed to investigate if this is due to age-related dermatological changes resulting in altered conductivity. Disclosure of Interest: None declared.
