Abstract:Erythrina crista-galli is a native tree from South America with an important role on pharmaceutical studies. The objective of this study was to model the ancient and current ecological niches distribution of E. crista-galli in South America, contributing to the discussion about species management and conservation. A reduction in the potential area of species occurrence was detected by comparing past and present distribution. Based on the obtained results, it is expected that this species tends to expand its fr… Show more
“…Furthermore, the roots of species in the genus Derris such as D. elliptica found in Southeast Asia and the southwest Pacific islands are a source of the strong insecticide rotenone [90]. And well-known ornamentals are the cockspur coral tree Erythrina crista-galli L., the national tree of Argentina, and the national flower of Argentina and Uruguay [91], and the Chinese wisteria Wisteria sinensis (Sims) DC that is a much appreciated ornamental vine [92].…”
The consumption of diets rich in antioxidants may minimize the chances of developing debilitating diseases such as cardiovascular, diabetic, inflammatory, neoplastic, and cognitive disorders. The Fabaceae or pea family is the third most species-rich plant family on Earth and includes more than 19,000 species in over 700 genera. Many species of Fabaceae are ingredients of staple diets and medicinal substances. This may be attributable to the presumably high content of antioxidants in these plants, particularly phenolic compounds. The Republic of Suriname (South America) harbors over 400 species of Fabaceae in more than 100 genera and has a rich ethnopharmacological tradition that also involves a number of Fabaceae species. In this chapter, we evaluated the literature to determine whether the traditional use of eight of the medicinally most commonly employed Surinamese species of Fabaceae may be associated with their phenolic content and antioxidant activity. Our results suggest that this may hold true for Caesalpinia pulcherrima, Cajanus cajan, Clitoria ternatea, Desmodium adscendens, Lablab purpureus, and Tamarindus indica but not for Copaifera guyanensis and Dipteryx odorata, the bioactivities of which mainly seem to be determined by terpenoids and coumarins, respectively, without an apparent involvement of antioxidant effects.

“…Erythrina crista-galli L. (Fabaceae, Papilionoideae), popularly known as cockspur coral tree, is a tree species which occurs from Maranhão State to Rio Grande do Sul State, being more recorded in the Brazilian South region (Martins 2019). Its distribution area also extends through Bolivia, Paraguay, Argentina and Uruguay (Mello et al 2019). The species contributes to important environmental services, hosting several epiphytes species, and also attracting insects and hummingbirds due to their colorful flowering which give it an ornamental aspect (Gratieri-Sossella et al 2008).…”

“…The species contributes to important environmental services, hosting several epiphytes species, and also attracting insects and hummingbirds due to their colorful flowering which give it an ornamental aspect (Gratieri-Sossella et al 2008). It is also of great value for medicine and ecological restoration (Mello et al 2019). In Rio Grande do Sul State, the tree-cutting of this species is prohibited pursuant to Article 33 of State Law number 9.519/92 (Rio Grande do Sul 1992).…”
The main goals of this study were to verify the existence of integumentary seed dormancy in Erythrina crista-galli seeds from mature pods and evaluate the seedling emergence from newly collected seeds in two stages of physiological maturation. Methods of overcoming dormancy were tested by comparing seedling emergence rate, mean emergence time and emergence index, with treatments: TC -control; T1-sanded and soaked in water for 48 h; T2 -sanded and soaked in water for 24 h; T3 -soaked in water without heating at the initial temperature of 60 °C, until reaching room temperature; T4 -only sanded; T5 -immature seeds. The results indicate that: i) newly collected seeds from mature pods do not require treatment to overcome dormancy; ii) immature seeds have germination similar to newly collected mature seeds.Keywords: cockspur coral tree, Fabaceae, physical dormancy RESUMO -Efeito do estágio de maturação e tratamentos pré-germinativos na emergência de Erythrina crista-galli L. Os objetivos deste trabalho foram verificar a existência de dormência tegumentar em sementes maduras de Erythrina crista-galli e avaliar a emergência de plântulas de sementes recém-coletadas, em dois estágios de maturação fisiológica. Foram testados métodos de superação de dormência, comparando-se taxa de emergência, tempo médio de emergência e índice médio de emergência das sementes, sendo os tratamentos: TC -controle; T1 -lixadas e embebidas em água por 48 h; T2 -lixadas e embebidas em água por 24 h; T3 -embebidas em água, fora do aquecimento, à temperatura inicial de 60 °C até atingir temperatura ambiente; T4 -apenas lixadas e T5 -sementes coletadas de legumes imaturos. Os resultados indicam: i) sementes recém-coletadas de vagens maduras não necessitam de tratamento para superação de dormência; ii) sementes imaturas apresentam germinação similar as maduras recém coletadas.Palavras-chave: corticeira-do-banhado, dormência física, Fabaceae
Dalbergia is economically essential for its high-quality rosewood wood in fine furniture. Thus, there is a high demand for wood, which has led to illegal logging. Dalbergia calderonii Standl. is associated with tropical deciduous forests, where there is a high rate of deforestation, leading to the decline of the species' natural populations. The knowledge of its potential areas of presence and associated environments can contribute to species conservation. Here, we modeled the potential distribution of D. calderonii and identified areas with remnants. We found that the potential distribution model for D. calderonii predicts two geographically separate areas, one in southern Mexico and the other in northern Central America; thus, we also modeled them as two independent populations and compared their ecological niches. We transferred all models into the Last Interglacial, the Last Glacial Maximum, and the mid-Holocene climatic scenarios to understand the species' recent biogeographic history. We found that 65% of the species' potential distribution comprises sites with sparse vegetation and bare soil; besides, we found no significant differences between the niches of the Mexican and Central American populations. The transferences to the past scenarios showed that the potential history of the species distribution had been characterized by dynamics of expansions and contractions describing commonly geographical isolations but also including stages of continuum distributions. We suggest that future conservation strategies prioritize both populations independently, based on their disjunct distribution.
