Abstract Already threatened by deforestation, the Brazilian Cerrado—a complex and biodiverse tropical savannah that provides important ecosystem services—could experience climate warming of 1–5°C 2100. This could negatively impact sexual reproduction (considered particularly sensitive to temperature stress) in native plant species, potentially limiting production viable pollen, fruits, seeds; however, such impacts are largely unstudied wild species. To investigate potential effects higher temperatures on Cerrado species reproduction, developing inflorescences common widespread tree Byrsonima pachyphylla (Malpighiaceae) were passively heated situ from an early bud stage (by 3–4°C during daytime). Viability pollen samples (analyzed through vitro germination differential staining) fruit set (the proportion hand‐pollinated flowers developed into mature fruit) compared between control (ambient temperature) inflorescences, hypothesizing both would be lower inflorescences. However, daytime had no production, suggesting a strong resilience warming. Nevertheless, was significantly reduced, which have serious implications for future recruitment community structure, insect animal food chains, human populations, especially if representative other best our knowledge, this experiment is first manipulative vegetation situ.

India is one of the world's largest producers tree nuts, yet it paradoxically remains a net importer these commodities. This study aims to analyze demand for imported nuts in India, motivated by need understand factors contributing this imbalance. The primary objective calculate income elasticities and own- cross-price five categories using linear approximate almost ideal system model. Data sourced from monthly import records United Nations Comtrade database covering 2014 2022. considered are almonds, cashews, pistachios, walnuts, hazelnuts. Key findings reveal all normal goods. Cashews exhibit elasticity (1.2), indicating significant increase with rising incomes, while other show inelasticity. price-elastic (−1.3), price-inelastic. Compensated indicate notable substitution effects, particularly between almonds cashews. recommends enhancing domestic cashew production meet growing developing targeted marketing strategies address competitive dynamics within nut market. These aim reduce India's dependency on imports promote balanced, sustainable
