- Enhancing growth, nutrient uptake and flowering of Tagetes patula plants through the application of suspensions of Chlorella vulgarisPublication . Vieira, João; Saque, Moisés; Viana, Catarina; Rodrigues, Maria Helena; Guerreiro David Coelho, Luísa Isabel; Gama, Florinda; Varela, João; Pereira, Hugo; Reis, Mário; Pestana, Maribela; Correia, Pedro JoséTagetes patula L. is a prominent plant that is frequently used for its ornamental value. Marigolds are sources of various compounds of great interest to agricultural, pharmaceutical, and nutritional industries. Microalgae can be applied as a biostimulant as they have multifunctional properties in agriculture, namely facilitating nutrient uptake, improving crop performance and physiological status, and thus increasing tolerance to abiotic stress. This study evaluated the efect of applying Chlorella vulgaris as a plant biostimulant on the growth and fowering of T. patula plants. Microalgae suspensions were applied to the substrate at concentrations of 0.5, 2.0 and 5.0 g dry weight (DW) L−1. A set of plants without the application of microalgae was used as control. The use of microalgae had a positive impact on plant growth. Specifcally, C. vulgaris application resulted in greater height, while the highest concentration (5.0 g DW L−1) resulted in higher fresh weight. Microalgae application signifcantly promoted the earlier fowering of marigolds. The macronutrient and micronutrient values were statistically similar between the control plants and those treated with microalgae. When considering only the treated plants, there was a signifcant correlation between the concentration of C. vulgaris and the concentrations of N, P, Mn and Cu in the shoots of T. patula plants. Plants receiving higher concentrations of C. vulgaris exhibited higher levels of these nutrients. These results highlight the potential use of Chlorella vulgaris as an efective biostimulant for enhancing the growth, fowering, and nutrient uptake of T. patula, ofering valuable applications for improving ornamental plant production and, ultimately, agricultural sustainability.

- Understanding urban resilience and SDGs: a new approach in decision‐making for sustainable citiesPublication . Barcellos‐Paula, Luciano; de Castro Rezende, Aline; Gil‐Lafuente, Anna MaríaRecent crises exacerbate social, environmental, and economic problems affecting the Sustainable Development Goals (SDGs) and urban resilience. Urgent action is needed to address these issues. The paper aims to (i) broaden the debate on urban resilience and the SDGs and (ii) examine how the interconnection of Urban Spatial Resilience (USR) and the SDGs can contribute to sustainable cities and communities. The research is developed through a literature review and a bibliometric analysis, followed by a quantitative approach using modeling and simulation. The results reveal three critical elements that can impact urban resilience and sustainable development: SDG11, urban spatial structure resilience, and urban spatial form resilience. Other findings indicate that SDG13 and SDG6 have a significant indirect relationship with urban resilience. The study provides policy implications supporting urban resilience and the SDGs.
