Checklist of the Caesalpinioideae (Leguminosae) of Equatorial Guinea (Annobón, Bioko and Río Muni)

This study provides a checklist of the Caesalpinioideae (Leguminosae) present in Equatorial Guinea, comprising 52 genera and 124 taxa. Seven species are known from Annobón, 33 from Bioko and 109 from Río Muni. The best represented genus is Senna with eight species. In addition, bibliographic references for Caesalpinioideae (Leguminosae) from Equatorial Guinea have been gathered and checked. Fourteen species are included based on literature records, because their distribution ranges suggest they may occur in Equatorial Guinea, 11 introduced species could be naturalized, and 45 taxa are recorded for the first time from the country. This represents an increase of over 35% in the floristic knowledge of Caesalpinioideae from Equatorial Guinea. A statistical summary is presented at the end of the checklist.Peer reviewe

Catálogo preliminar de plantas vasculares de la isla de Bioko (Guinea Ecuatorial)

We present a list of taxa of vascular plants growing on Bioko (Equatorial Guinea). We are aware that there are still many unexplored areas,so it should be consider just as a first draft list. It is based on both herbarium specimens and on bibliographic references. The complete data, supportingeach record, can be consulted in our online database at http://www.floradeguinea.com/herbario/. To the moment, there are known 2029taxa from the island.Presentamos el catálogo de táxones de plantas vasculares que crecen en Bioko (Guinea Ecuatorial). Somos conscientes de que existen aun numerosas zonas inexploradas, de manera que debe ser considerada únicamente como una lista preliminar. El catálogo está basado tanto en material de herbario como en referencias bibliográficas. Los datos sobre los que se basa cada cita pueden consultarse directamente en nuestra base de datos en http://www.floradeguinea.com/herbario/. Hasta el momento se conocen 2029 taxones de la isla

Wiki-keys for the ferns of the Flora of Equatorial Guinea

Flora of Equatorial Guinea is a research project coordinated by the Real Jardín Botánico of Madrid with the aim to produce a modern Flora for this almost unknown territory. One of our goals is to develop the website www. floradeguinea.com. A system of relational databases with an implemented Thesaurus - to minimize typographical mistakes - allows the on-line managing and updating of nomenclatural information, herbarium specimens, literature records, vernacular names and bibliography. Images and maps are also linked to accepted names. We are now implementing interactive keys for identification. In our wiki-based system, Scans of herbarium specimens from all species growing in the country are also being uploaded. Species from neighboring countries are included as well, since some of them could appear in Equatorial Guinea

Highly efficient Cu2O@CuxFeyO4 nanohybrid catalyst for the degradation of emerging pollutants

Cu2O@CuxFeyO4 nanohybrids (NHs) have been electrosynthesized by a simple and environmentally safe method to be used as catalysts for tetracycline degradation. NHs shown an average diameter of 14(5) nm and exhibit high crystallinity with spherical morphology. XPS results demonstrate a cuprite-enriched surface; meanwhile, the inner layer is composed by a nonstoichiometric copper spinel structure. The degradation has been monitored by UV–Visible spectroscopy, TOC analysis, and HPLC. The electrochemical characterization demonstrates the synergetic effect of Fe3+/Fe2+ and Cu2+/Cu+ coupling to enhance the activation of persulfate. This effect results in a greater degradation efficiency of NHs than other catalysts, namely, CuxOy, Fe3O4, and a mixture of both and Cu2O. It has been found that a previous adsorption stage before degradation does not improve the elimination of the pollutant and its length in time, with a TOC reduction of 72.6 % in 2 h. Conversely, conducting the oxidative process in a direct step resulted in a more rapid and efficient process, 82.3 % of reduction in 1 h. Through this method, the catalyst reutilization resulting in a decrease of 50 % in TOC degradation from the third use, while the TCY concentration degraded remains almost constant. This reduced catalytic activity with use might be a consequence of 1) the absence of the single Cu-oxide layer due to the leaching of mainly Cu ions but also Fe ions during the degradation tests, and, 2) the passivation of the outermost layer, mainly covered by C–O species and OH groups, which hinders access to active catalyst sitesThis research was funded by the Madrid Government (Comunidad de Madrid-Spain) under the Multiannual Agreement with Universidad Autonoma ´ de Madrid in the line of action encouraging youth research doctors, in the context of the V PRICIT (Regional Programme of Research and Technological Innovation) (SI1-PJI-2019-00366) and by the Spanish Ministry of Science and Innovation under project PID2021- 123431OB-I00.
