The Jambu, an herbaceous plant widely consumed in the Amazon in typical dishes and in natura, is also found in Central America, Asia, and even in Europe. Its behavior when exposed to heavy metals is unknown and, being Cd one of the most phytotoxic metals, the objective is to elucidate how Cd influences nutrient uptake by jambu. The experimental design was entirely randomized with five treatments and six repetitions, in a hydroponic culture system. Four doses of Cd (1, 3, 6 and 9mg/L), plus a control were used. At the end of the experiment, chemical analyses were performed to quantify the content of K, Mg, Ca, Fe, Zn, Mn and Cu in the leaf, stem, inflorescence and root. The results were submitted to ANOVA and regression analysis and show a significant increase in K, Mg and Ca, up to a dose of 6mg/L of Cd. The micronutrients Fe, Zn, Mn and Cu also showed a significant increase in the absorption, until the dose of 6mg/L. The difference in uptake ranged from 23.02% for Cu to 151.9% for Ca in relation to the uptake of the nutrients by the control plants. The dose of 9mg/L, produced an antagonistic effect, with a reduction in the uptake of the nutrients, with the exception of Ca. In general, Cd in small doses produced in the jambu a stimulant effect and in larger doses, a toxic effect. This behavior indicates a hormetic effect of jambu against Cd.

Climate change has been affecting many coastal communities around the world. With the location of the Philippines in the tropics, the country is vulnerable to the impacts brought by this phenomenon affecting the safety, livelihood, and income distribution of the fishing communities in particular. Quantifying adaptive capacity to climate change is critical in reducing the vulnerability of these affected communities. This study was conducted to assess the adaptive capacity in the household level of the different social groups in the fishing communities of the Municipality of Sindangan, Zamboanga del Norte, Philippines. Using the interval-level scale generated from the eight indicators of adaptive capacity comprising human agency, capacity to change, occupational mobility, material assets, occupational multiplicity, social capital and infrastructure, and the Analytical Hierarchy Process (AHP), the data revealed differentiation between social groups. The result showed that fishers who are land tenants, members in fishing boats, large household sizes, fishers belonging in the age group of 29 to 36 years old, and fishers who finished High School are least prepared for the changes in climate. The findings of this study support previous findings of the adaptive capacity conducted around the world. These results highlight the most vulnerable sectors of society, which will help guide local policymakers to formulate environmental adaptation plans appropriate for the social groups in a fishing community.
