Resumen El Parque Nacional Natural Munchique conserva ecosistemas estratégicos de Selva Inferior, Subandina y Andina, que han sido alterados por factores antrópicos; por ello, implementa una estrategia de restauración ecológica pasiva como alternativa para recuperar cobertura vegetal y proteger la biodiversidad. El monitoreo se realizó en un bosque subandino con 20 transectos tipo Gentry en dos procesos denominados restauración avanzada y restauración temprana, solo para los años 2013, 2015 y 2017, debido al orden público. Se censaron los individuos con DAP ≥ 1 cm. La riqueza en restauración avanzada fue de 35/2013, 39/2015 y 45/2017 especies mientras que en restauración temprana se registró una riqueza de 31/2013, 44/2015 y 45/2017. En los tres periodos de muestreo y para ambos procesos, las familias Rubiaceae y Melastomataceae fueron las más frecuentes. Restauración avanzada presentó una marcada dominancia de Miconia theizans con el 98 %/2013, 83 %/2015 y 65 %/2017 para el valor de importancia (IVI) y en restauración temprana la especie más importante fue Meriana speciosa con el 38 %/2013, 50 %/2015 y 55 %/2017. El monitoreo a largo plazo en ambos escenarios de restauración permitió evidenciar una recuperación lenta, pero efectiva para el aumento en diversidad y mejoramiento de la estructura vegetal.

Abstract The Munchique National Natural Park conserves strategic ecosystems that have been altered by anthropogenic factors; therefore, a passive ecological restoration strategy is implemented as an alternative to recover plant cover and protect biodiversity. The monitoring was carried out in a sub-Andean forest through 20 Gentry-type transects in two processes called advanced restoration and early restoration, only for the years 2013, 2015 and 2017, for reasons of public order. Individuals with DBH ≥ 1 cm were censored. The richness in advanced restoration was 35/2013, 39/2015 and 45/2017 species, while in early restoration a richness of 31/2013, 44/2015 and 45/2017 was recorded. In the three sampling periods and for both processes, the families Rubiaceae and Melastomataceae were the most frequent. Advanced restoration presented a marked dominance of Miconia theizans with 98 %/2013, 83 %/2015 and 65 %/2017 for the importance value (IVI) and in early restoration the most important species was Meriana speciosa with 38 %/2013 , 50 %/2015 and 55 %/2017. Long-term monitoring in both restoration scenarios revealed a slow but effective recovery for increased diversity and improved plant structure.

ABSTRACT Mistletoe is an important nutritional resource for the frugivorous ornithological fauna in several ecosystems. However, in great intensity, they can reduce the vigor of their host trees, requiring adequate management in urban afforestation, without depleting this source of food for birds. The hypothesis that there are hemiparasites with host specificity was the reason for this study. Thus, a floristic census of the trees was carried out at UFMT, campus Cuiabá; the infestation by genus of hemiparasite present was recorded, in quantity and degree of infestation, in addition to the quantification of seeds of the hemiparasite germinated without the development of the vegetative part, whose cotyledons necrotized and died. A total of 4265 tree individuals were evaluated, distributed in 46 families, in which 16,52% were identified of the genera Phoradendron, Psittacanthus, and Struthanthus, of which about 90,0% were Psittacanthus. The highest infestation occurred in 24 families, highlighting Fabaceae (28,3%) and Combretaceae (25,6%), and the species Terminalia catappa, Anadenanthera peregrina, and Vatairea macrocarpa. The presence of germinated seeds of the hemiparasite with dead cotyledons varies between tree species and between individuals of the same species. The highlight was in Rutaceae, Arecaceae, and Rubiaceae, and in the species Acrocomia aculeata, Caryocar villosum, and Genipa americana L. that present individuals with natural control potential, even with the presence of frugivorous ornithological fauna and the dispersion of the hemiparasite. In general, the intensity and degree of infestation are low, and there is no infestation in the Caryocaceae, Rutaceae, and Rubiaceae families, highlighting the species Caryocar villosum, Murraya paniculata and Alibertia edulis.

RESUMO As ervas-de-passarinho compõem um importante recurso nutricional para a fauna ornitológica frugívora em vários ecossistemas. Porém, em grande intensidade, podem diminuir o vigor de suas árvores hospedeiras sendo necessário manejo adequado na arborização urbana, sem exaurir essa fonte de alimento aos pássaros. A hipótese de que existam hemiparasitos com especificidade de hospedeiro foi a motivação para este trabalho. Assim, foi realizado censo florístico arbóreo na UFMT, campus Cuiabá; registrada a infestação por gênero de hemiparasito presente, em quantidade e grau de infestação, além da quantificação de sementes do hemiparasito germinadas sem o desenvolvimento da parte vegetativa, cujos cotilédones necrosaram e morreram. Avaliaram-se 4265 indivíduos arbóreos, distribuídos em 46 famílias nas quais 16.52% foram identificados os gêneros Phoradendron, Psittacanthus e Struthanthus, dos quais cerca de 90.0% eram Psittacanthus: A maior infestação ocorreu em 24 famílias, destacando-se Fabaceae (28.3%) e Combretaceae (25.6%) e as espécies Terminalia catappa, Anadenanthera peregrina e Vatairea macrocarpa: A presença de sementes germinadas do hemiparasito com cotilédones mortos é variável entre as espécies arbóreas e entre os indivíduos da mesma espécie. O destaque foi em Rutaceae, Areacaceae e Rubiaceae, e nas espécies Acrocomia aculeata, Caryocar villosum e Genipa americana L: que apresentam indivíduos com potencial natural de controle, mesmo com a presença da fauna ornitológica frugívora e a dispersão do hemiparasito. De forma geral, a intensidade e o grau de infestação são baixos e não há infestação nas famílias Caryocaceae, Rutaceae e Rubiaceae, com destaque para as espécies Caryocar villosum, Murraya paniculata e Alibertia edulis.

ABSTRACT Genipa americana L. is a forest species of high socioeconomic potential. However, predatory extractivism actions threaten its existence, making it necessary to adopt conservationist practices. G. americana seeds show sensitivity to desiccation and cooling, making it unfeasible for conservation by conventional methods. Thus, cryopreservation is an promising alternative for the long-term conservation of species that produce unorthodox seeds, such as the genipap. In this sense, the objective was to cryopreservation of seeds of G. americana and to evaluate the effects of desiccation and freezing on germination and establishment of seedlings. Initially, seeds were dehydrated in silica gel 0, 16, 18, 20, 22 and 24 h, and then were cryopreserved in liquid nitrogen (LN) (-196 °C) during 24 h. After thawing, the viability and germination were analyzed. Dehydrated and non-cryopreserved seeds were also analyzed. The silica gel desiccation caused a reduction in viability and germination of the seeds of G. americana. The initial seed water content was so high (47%) that storage in LN (+LN) without prior dehydration treatment resulted in seed mortality. It was verified that, the dehydration in silica gel for the minimum time 20 h (corresponding to 14% water content) provides greater freezing tolerance, allowing the successful cryopreservation. Silica gel dehydration followed by immersion in LN was shown to be highly efficient for cryopreservation of seeds of G. americana, besides germinatio after thawing, high survival rates (100%) were obtained, with growth and normal establishment of the seedlings after acclimatization.

Abstract Morinda citrifolia, commonly known as noni, is a plant belonging to the Rubiaceae family. This plant has a high biological potential, which has different biological properties, including antioxidant, antibacterial, antiviral, antifungal, antitumor and anti-inflammatory. In this work, the immunomodulatory, antitumor and antimicrobial activities of lignin isolated from Morinda citrifolia leaves were investigated. The results showed that this lignin was not cytotoxic and that it was able to promote activation and differentiation of immune cells in addition to inducing the production of anti-inflammatory cytokines. Furthermore, it was able to inhibit the growth of different tumor and microbial cells in vitro. This pioneering study on these different activities shows that the lignin isolated in this study can be used as a raw material to obtain biomedical and pharmaceutical products. noni family potential properties antioxidant antibacterial antiviral antifungal antiinflammatory. antiinflammatory anti inflammatory. inflammatory work immunomodulatory investigated cytokines Furthermore vitro products

Abstract: Background and Aims: During explorations in the outer limits of the Natural Protected Area Sierra de Tacuichamona, an endemic-rich area of Sinaloa, Mexico, a new species of Coutaportla (Rubiaceae) was discovered. This paper describes and illustrates Coutaportla helgae, provides an identification key, a distribution map, and discusses the morphological and geographic relationships with the rest of the species of the genus. Methods: Botanical collections were made during 2021 and 2022, and 15 herbariums and digital databases were reviewed to compare with other species of the genus and to locate possible additional localities. A distribution map was prepared using the polygon of the Sierra Madre Occidental as a base. Key results: Coutaportla helgae stands out from the rest of the species of the genus by having the smallest flowers of the group. It is morphologically related to C. lorenceana as they are the only species of the genus with subapical placentation and calyx lobes less than half the length of the fruit, but it differs in having smaller flowers, a shrubby habit and distribution in tropical deciduous forest. Conclusions: With the present discovery, Coutaportla reaches four endemic species to Mexico and five overall, considering C. guatemalensis. Coutaportla helgae contributes new characteristics to the genus by having smaller flowers and growing at lower altitudes than the rest. Additionally, elements are provided to support the conservation of sites with high biodiversity and endemism such as the Sierra Tacuichamona.

Resumen: Antecedentes y Objetivos: Durante exploraciones en los límites exteriores del Área Natural Protegida Sierra de Tacuichamona, zona rica en endemismos de Sinaloa, México, se descubrió una especie nueva de Coutaportla (Rubiaceae). El objetivo del presente trabajo es describir e ilustrar a Coutaportla helgae, proveer una clave de identificación y un mapa de distribución, y discutir las relaciones morfológicas y geográficas con el resto de las especies del género. Métodos: Se realizaron colectas botánicas durante 2021 y 2022, y se revisaron 15 herbarios y bases digitales para comparar con otras especies del género y localizar posibles localidades adicionales. Empleando el polígono de la Sierra Madre Occidental se elaboró un mapa de distribución. Resultados clave: Coutaportla helgae se destaca del resto de especies del género al poseer las flores más pequeñas del grupo. Se relaciona morfológicamente con C. lorenceana al ser las únicas especies del género con placentación subapical y lóbulos del cáliz menor a la mitad del largo del fruto, pero se diferencia de esta por tener flores de menor tamaño, corolas blanco-púrpuras, hábito arbustivo y distribución en selva baja caducifolia. Conclusiones: Con el presente descubrimiento, el género Coutaportla llega a cuatro especies endémicas de México y cinco en total, considerando a C. guatemalensis. Coutaportla helgae aporta nuevas características al género, pues posee las flores más pequeñas y crece a menores altitudes que el resto. Adicionalmente, se aportan elementos para apoyar la conservación de sitios altos en biodiversidad y endemismos como la Sierra Tacuichamona.

Abstract The state of Ceará is located in the Northeast region of Brazil, which has a varied climatic condition, being predominantly formed by Caatinga vegetation, and there may also be remnants of Cerrado and other Semideciduous Seasonal Forest. The objective of this work was to carry out a floristic survey in vegetation fragments of Semideciduous Seasonal Forest and Cerrado found in the part of Serra das Flores located in the municipality of Viçosa do Ceará. Para tal, foram realizadas 12 coletas na área ao longo do ano de 2019. 220 species were recorded, belonging to 154 genera and 62 families. The most representative families in this area were Fabaceae (38 spp.), Rubiaceae (15 spp.) and Myrtaceae (nine spp.). The predominant habit were herbs and shrubs. The richest fragment was the Cerrado with 171 species, with the Typical Cerrado (104 spp.) phytophysiognomy being the most representative. Of the total species, most are native, 16 are new records for Ceará, 12 are endemic to the Caatinga domain and seven are endemic to the Cerrado. Thus, the present site presents a high heterogeneity of species, in addition to varied habits, new records and endemic species of Cerrado and Caatinga.

Resumo O estado do Ceará fica localizado na região Nordeste do Brasil, a qual possui uma variada condição climática, sendo formado predominantemente de vegetação de Caatinga, podendo também ocorrer remanescentes de Cerrado e de Floresta Estacional Semidecidual. O objetivo deste trabalho foi realizar o levantamento florístico em fragmentos vegetacionais de Floresta Estacional Semidecidual e Cerrado encontrados na parte da Serra das Flores localizada no município de Viçosa do Ceará. Para tal, foram realizadas 12 coletas na área ao longo do ano de 2019. Foram registradas 220 espécies, pertencentes a 154 gêneros e 62 famílias. As famílias mais representativas nessa área foram Fabaceae (38 spp.), Rubiaceae (15 spp.) e Myrtaceae (nove spp.). Os hábitos predominantes foram as ervas e os arbustos. O fragmento mais rico foi o de Cerrado com 171 espécies, sendo a fitofisionomia de Cerrado Típico (104 spp.) a mais representativa. Do total de espécies, a maioria são nativa, 16 são novos registros para o Ceará, 12 são endêmicas do domínio Caatinga e sete são endêmicas de Cerrado. Com isso o presente local apresenta uma alta heterogeneidade de espécies, além de variados hábitos, novos registros e espécies endêmicas de Cerrado e Caatinga.

Abstract Studies related to reclamation on asphalt post-mining land are lacking. This study aimed to analyze the diversity of vegetation on asphalt post-mining sites in Buton, Southeast Sulawesi Province, Indonesia. The study focused on the composition, structure and diversity of plants on asphalt post-mining sites with varying ages (0-20 years) and overburden conditions. In total, this study recorded 105 plant species belonging to 37 families with richness index of 0.33-6.30 (low-high), diversity index of 0.31-2.96 (low-medium), and evenness index of 0.28-0.94 (low-high). The highest number of plant species was observed on the 7-year-old overburden site (46 species), suggesting that post-mining age is not necessarily the determinant factor of vegetation condition. There was arrested succession on the post-mining site with no overburden, implying that management of overburden is essential. Our study recommends that active planting using species from Rubiaceae family can be applied for reclamation of degraded land on asphalt post-mining areas.

Abstract Background: The genus Randia L. (Rubiaceae) is native to Americas and highly distributed in tropical areas. Some Randia species are used in traditional medicine in some countries to treat diverse illnesses/symptoms of kidney, circulatory system, lungs, diabetes, cancer, inflammation, and against the bites/stings of snakes and other poisonous animals. Questions: What are the phytochemical compounds previously identified in Randia? What biological activities do they present? Data description: Twenty-eight studies on chemical composition and biological activities of Randia were reviewed. Species names were corroborated in Plants of the World Online and World Flora Online. The site and studied years: Studies of Randia of Americas from 1991 to 2021. Methods: Database reviewed were PubMed, Scopus, Scielo, BVS, DAOJ, Science Direct, Springer Link, Web of Science, and Google Scholar, employing the keywords Randia and its synonym Basanacantha. Results: Six species are the most studied (R. aculeata, R. echinocarpa, R. ferox, R. hebecarpa, R. matudae, and R. monantha). Ethnopharmacology information of 12 species was recovered. One hundred compounds in Randia have been identified (phenolic acids, terpenes, sterols, and others), and diverse biological activities reported in 24 studies (e.g., antimutagenic, antioxidant, and antivenom) have demonstrated for nine species. Conclusions: Biological activities found in some species of Randia support their traditional uses, but only the antivenom effect of Randia aculeata has been demonstrated. Randia species could be a source of bioactive compounds; however, knowledge must be expanded to demonstrate their traditional uses and contribute to the development of strategies for their preservation and rational use.

Resumen Antecedentes: El género Randia L. (Rubiaceae) es originario de América y está altamente distribuido en zonas tropicales. Algunas de sus especies son utilizadas en la medicina tradicional de algunos países para tratar diversos padecimientos/síntomas: renales, circulatorios, pulmonares, diabetes, cáncer, inflamación y contra las mordeduras/picaduras de serpientes y animales ponzoñosos. Preguntas: ¿Cuáles son los compuestos fitoquímicos identificados en Randia? ¿Qué actividades biológicas presentan? Descripción de datos: Se revisaron 28 estudios sobre composición química y actividades biológicas de Randia. La nomenclatura se corroboró en Plants of the World Online y World Flora Online. Sitio y años de estudio: Estudios de Randia de América desde 1991 a 2021. Métodos: Las bases de datos revisadas fueron PubMed, Scopus, Scielo, BVS, DAOJ, Science Direct, Springer Link, Web of Science y Google académico, empleando las palabras clave Randia y su sinónimo Basanacantha. Resultados: Seis especies de Randia son las más estudiadas (R. aculeata, R. echinocarpa, R. ferox, R. hebecarpa, R. matudae y R. monantha). Se recuperó información etnofarmacológica de 12 especies. Cien compuestos han sido identificados en Randia (ácidos fenólicos, terpenos, esteroles y otros) y demostrado diversas actividades biológicas en 24 estudios (e.g., antimutagénica, antioxidante, antiveneno) para nueve especies. Conclusiones: Las actividades biológicas de especies de Randia soportan sus usos tradicionales, pero solo está demostrada la actividad antiveneno de R. aculeata. Especies de Randia podrían ser fuente de compuestos bioactivos, pero su conocimiento debe incrementarse para demonstrar sus usos tradicionales y contribuir al desarrollo de estrategias para su preservación y uso racional.

Abstract Background: The Rubiaceae family is one of the most diverse in Mexico, and it is the fourth in diversity among angiosperms. There have been several efforts to characterize its diversity, resulting in differences in the number of genera and species registered for Mexico: 77-113 genera and 510-707 species. This discrepancy highlights the need to critically review the studies that list the diversity of Rubiaceae of Mexico, with the aim of presenting an overview to elucidate the state of their knowledge. Questions: What is the diversity of the Rubiaceae in Mexico? At what taxonomic level is the problem? How are diversity and endemism distributed? What is the collection effort? Studied species: Rubiaceae Study site: Mexico Methods: A database was generated from the review of the main floristic works of Rubiaceae from Mexico, complemented with information from herbarium databases. Results: The Rubiaceae family in Mexico is represented by 111 genera, of which 17 are endemic, with 711 native species, 363 of which are endemic, and 13 exotic species. The most speciose states are Oaxaca (416), Chiapas (365) and Veracruz (318), in which 50 % of the endemism is concentrated. The collection effort suggests that 43 % of the territory sufficient collections. Conclusions: This work presents a revised taxonomic list and proposals that solve conflicts at generic level; highlighting the need to carry out taxonomic work focused on some groups and to continue with the efforts of collecting and reviewing herbaria for a more accurate approach to assessing the Rubiaceae diversity in Mexico.

El objetivo de esta contribución es reportar por primera vez la presencia de esta especie adventicia para la flora de Paraguay y Argentina. M&M : Se estudiaron plantas vivas y material de herbario, tanto como la descripción original de Oldenlandia corymbosa. Se realizaron análisis taxonómicos y morfológicos. El material coleccionado fue depositado en FCQ y CTES. Resultados : Se proporciona una descripción de la morfología y hábitat de la especie sobre la base de especímenes de herbario y observaciones de campo, junto con una ilustración, fotografías, y un mapa que indica la posición geográfica de las poblaciones registradas en el nordeste y sur de Paraguay y nordeste de Argentina en la provincia de Corrientes. Complementariamente, se proporciona una clave de identificación de las especies de Oldenlandia presentes en Argentina y Paraguay. Conclusiones : Con el registro de Oldenlandia corymbosa en Paraguay y Argentina, se amplía el rango de distribución de esta especie alóctona hasta el Cono Sur de América del Sur. Su estatus de especie naturalizada en Paraguay plantea la posibilidad de que fuera, hasta ahora, ignorada en otras regiones del Nordeste Argentino.

SUMMARY Background and aims : During the revisión of the Southern South American species of Oldenlandia, populations of O. corymbosa were found in Paraguay and Argentina. The aim of this contribution is to report the presence of this adventitious species to the Paraguayan and Argentinian flora for the first time. M&M : Living plants and herbarium material, as well as the original description of Oldenlandia corymbosa were analysed. Taxonomic and morphological analyses were performed. Collected materials were deposited in FCQ and CTES. Results : A description of the morphology of the species and habitat based on herbarium specimens and field observations are provided, along with an iNustration, photographs, and a map indicating the geographical position of the recorded populations in the Northeast and South Paraguay and Northeast Argentina in the Corrientes province. Complementary, an identification key of Oldenlandia species occurring in Argentina and Paraguay is provided. Conclusión : With the record of Oldenlandia corymbosa in Paraguay and Argentina, the range of distribution of this non-native species is extended up to the Southern Cone of South America. Its status of naturalized species in Paraguay raises the possibility that it was, until now, overlooked in other regions of the Northeast Argentina.

RESUMEN Los ecosistemas andinos constituyen uno de los más importantes centros de biodiversidad del mundo, sin embargo, sus coberturas boscosas tienden a desaparecer rápidamente debido a que están sometidas a una fuerte presión antrópica. En este estudio, se caracterizan las angiospermas presentes en los parches de bosque, sus bordes y en zonas de vegetación abierta o potrero de un área andina de la Cordillera Central de Colombia. Entre marzo de 2017 y febrero de 2018 se realizaron recolecciones de material fértil mediante recorridos del área. Se obtuvo información complementaria de colecciones históricas depositadas en herbarios. El material herborizado se depositó en el Herbario Nacional Colombiano (COL). Se registran 431 especies, agrupadas en 92 familias y 239 géneros, se encontraron cinco familias de magnólidas con siete géneros y 29 especies, 18 de monocotiledóneas (66/131) y 69 eudicotiledóneas (166/271). La mayor riqueza a nivel de especies la presentan Orchidaceae (54), Rubiaceae (24), Asteraceae (22), Araceae (22) y Piperaceae (20). Las hierbas terrestres son la forma de vida más numerosa (31,8 %), seguidas por arbustos (26,5 %) y árboles (17,6 %). A pesar de tratarse de áreas rodeadas por actividades productivas, principalmente agropecuarias, se encontraron 30 especies endémicas de Colombia, 170 taxones representan nuevos registros para la vertiente oriental de la Cordillera Central del departamento de Antioquia, dos nuevos registros para el departamento y cuatro nuevas especies.

ABSTRACT The Andean ecosystems constitute one of the most important centers of biodiversity in the world; however, their forest covers tend to disappear rapidly as they are subjected to strong anthropic pressure. In this study, the angiosperms present in the forest patches, its edge, and in areas of open vegetation or pasture of an Andean area of the Central Cordillera of Colombia are characterized. General collections of fertile material were made through tours between March 2017 and February 2018. Complementary information was obtained from historic collections deposited in herbaria and the botanical material was deposited in the Herbario Nacional Colombiano (COL). A total of 431 species are recorded, grouped into 92 families and 239 genera, five families of magnolids were found with seven genera and 29 species, 18 monocotyledons (66/131) and 69 eudicotyledons (166/271). The highest species richness is presented by Orchidaceae (54), Rubiaceae (24), Asteraceae (22), Araceae (22), and Piperaceae (20). Terrestrial herbs is the most numerous life form (31.8 %), followed by shrubs (26.5 %) and trees (17.6 %). Despite being areas surrounded by productive activities, mainly agricultural, 30 species are endemic to Colombia, 170 taxa are new records for the eastern slope of the Central mountain range of the department of Antioquia, two are new records for the department, and four new species are reported.
