“…This occurrence of Z. joazeiro in the coastal region can be explained by the great capacity that some species of the Caatinga must adapt to disturbed environments (with vegetation removed), thus being able to call them "ruderal". According to Costa et al (2016b), the species has a high potential to develop in different environments, adapting well to soils with different textures and chemical compositions. Thus, the abundance of Z. joazeiro in the transition areas may have allowed the species to use this plasticity to colonize new areas, especially in environments with no competition from Atlantic Forest species.…”

Species distribution models have become an essential tool for the selection of conservation areas. Given this perspective, this research aimed to analyze the dynamics of the fundamental niche of Ziziphus joazeiro Mart. facing climate change. The MaxEnt algorithm was used to correlate species points of occurrence with bioclimatic variables of four periods: Middle Holocene, current period, and the optimistic and pessimistic future scenarios of the HadGEM2-ES model of general atmospheric circulation. The accuracy of the predictions and the influence of the variables was evaluated using the area under the curve (AUC index) and the Jackknife test. The predictions showed high precision (AUC > 0.895), and the bioclimatic variables related to precipitation were the ones that most contributed to determining potential areas for the occurrence of the species. A reduction of more than 60% was observed in the area with climatic suitability for the occurrence of Z. joazeiro, over time. The range that comprises the central region of the distribution of the species stands out as the region with the greatest suitability, as projected for the current and future period, this being the area that should receive the most attention for the conservation programs of the species.

“…These results corroborate the findings of Trovão et al (2007) which confirming that this species has phenotypic plasticity for adaptations to water stress. Likewise, Souza et al (2015) have shown that species that remain always green throughout the year, such as Z. joazeiro, exhibit a set of foliar functional traits related to the drought tolerance strategy, adapting to different textures of soils and chemical compositions (Costa, Silva, Coelho, Santos, & Seabra, 2016).…”

Water availability is a critical point for dryland recovered on tropical regions of the world. This problem to become higher with the lacking information about the ecophysiologial behavior of the native plants on the initial growth stage under field conditions, mainly when these plants are submitted to different water availability levels. To address this question, we evaluated different water management strategies on the ecophysiological features of the five young native plants establishment in a degraded area located in the Caatinga, a dryland Brazilian forest. The water management strategies effects on native plants were checked by analyzing the photosynthesis rates, gas exchange and photochemistry efficiency in leaves of Crataeva tapia, Erythrina mulungu, Handroanthus impetiginosus, Tabebuia aurea and Ziziphus joazeiro. The experiment had four treatments (waterbox use, bovine manure, hydrogel, bovine manure plus hydrogel) and control. In the initial growth stage and under field conditions, the effects of water stress or water deficiency on the photosynthetic rates, gas exchange and chlorophyll fluorescence a of the T. aurea, H. impetiginosus, C. tapia and E. mulungu, exposed to waterbox and hydrogel, associated or not with bovine manure, were partially or totally mitigated. The Z. joazeiro species has the adaptive intrinsic characteristics that allow them to with stand the most stressful environmental conditions and this naturally allowed presenting greater water use efficiency and absence of damage to the photosynthetic apparatus and high Fv/Fm ratio. In general, the water management strategies studied have alleviated the effects of water stress, totally or partially, on the ecophysiological processes of young native plants under field conditions.

“…O Ziziphus joazeiro, conhecido popularmente como juá, juazeiro, é endêmico da caatinga, e possui uma grande resistência a períodos de seca devido ao seu desenvolvimento radicular complexo. O desenvolvimento dessa planta é lento, com dificuldade na germinação das sementes, o que compromete a sobrevivência da espécie, uma vez que a atividade humana desenfreada na região ocasiona problemas no seu ecossistema (COSTA et al, 2016). É encontrada principalmente no Nordeste do Brasil, possuindo uma grande importância social e econômica para a população dessa região (OLIVEIRA et al, 2012).…”

O Ziziphus joazeiro, planta conhecida popularmente como juazeiro ou juá, é oriunda da Região Nordeste do Brasil, sendo culturalmente utilizada nessa região. O presente trabalho teve como objetivo realizar um mapeamento científico e tecnológico da espécie Ziziphus joazeiro, com o intuito de analisar os impactos tecnológicos dentro do meio de produção, traçando perspectivas e diminuindo as incertezas de mercado para aplicação de tecnologias. A prospecção científica foi realizada na base de dados Web of Science TM, e para o mapeamento tecnológico as pesquisas foram realizadas em 7 plataformas de depósitos de patentes, nacionais e internacionais. Os descritores de busca foram as palavras-chave: juá, Ziziphus joazeiro e juazeiro. Foram encontradas 67 publicações científicas e 910 citações, além de 53 patentes relacionadas à tecnologia e à inovação, sendo os principais países depositantes os Estados Unidos e o Brasil e com predominância na área de produção de produtos para higiene pessoal.
