“…Borhidi que crece en Mesoamérica. Dentro del género se reconocen tres centros de concentración sudamericanos según el número de especies: el primero se ubica en Brasil con 39 especies, seguido de Paraguay con 20 especies, y Bolivia con siete especies (Florentín et al, 2022a).…”

“…Las especies de este género habitan principalmente en campos rupestres, campos bajos, sabanas y laderas de cerros, y crecen sobre suelos lateríticos, arenosos o con afloramientos rocosos (Florentín et al, 2022a). Morfológicamente, las plantas se caracterizan por presentar un porte erecto, xilopodio o raíz primaria, flores generalmente distilas dispuestas en inflorescencias tirsoideas laxas, estilo bífido, ovario bicarpelar, y fruto con valvas dehiscentes o mericarpos indehiscentes (Cabral, 1991;Cabral & Bacigalupo, 1997;Cabral, 2009).…”

Galianthe valerianoides (Spermacoceae-Rubiaceae) es registrada por primera vez para la flora de Uruguay (Dpto. Rivera), y como consecuencia, el área de su distribución se extiende hasta su límite más austral. Se presenta una descripción morfológica detallada, un mapa de distribución en el Uruguay, y fotografías del hábitat de G. valerianoides. Asimismo, se proporciona una clave de las especies de Galianthe que crecen en Uruguay.

“…The same result (called the south centre) was obtained by Souza et al (2021); however, these authors found that the region with higher endemism is located along the Serra Geral. This area of endemism has already been identified in studies with angiosperms (Murray-Smith et al, 2008;Menini-Neto et al, 2016;Florent ın et al, 2022), arthropods (Hoffmeister and Ferrari, 2016), bees (Garraffoni et al, 2017), birds (Cracraft, 1985), flatworms (Lago-Barcia et al, 2020), harvestmen (Da Silva et al, 2015, hemipterans (Goldani and Carvalho, 2003), insects (Goldani et al, 2002), mammals (Dalapicolla et al, 2021) and moths (Ferro and Melo, 2010). The limits of this AoE are not all congruent for these taxa; however, practically all studies have encompassed the eastern region of Santa Catarina and Rio Grande do Sul (from the Serra Geral to the coast).…”

“…The EI were also proportional to grid size (analysis 1 ranged from 2.35 to 4.58, and analysis 5 from 2.04 to 15.66-Table 1), as well as the number of species (for example, south of Brazil area in analysis 1 is defined by four species, already in analysis 5 for 15 species). Several previous studies have commented on the influence of this parameter on the results (Szumik et al, 2002;Casagranda et al, 2009;Prado et al, 2015;Andrade-D ıaz et al, 2017;Daru et al, 2020;Lago-Barcia et al, 2020;Pacifico et al, 2020;Florent ın et al, 2022). Very small grids result in discontinuous distributions, thus few (or even none) and small AoE are defined (Szumik et al, 2002).…”

Areas of endemism of Pteridaceae (Polypodiopsida) in Brazil: a first approach

Areas of endemism (AoE) comprise regions host to two or more endemic taxa, whose distributional limits are congruent and not random. These areas are important for two reasons: they comprise the smallest geographic units for biogeographic analyses and they are priority targets for conservation actions. Ferns are a monophyletic group that despite having a wide geographic distribution, concentrates great species richness and endemism in some regions (centres). The southern and southeastern regions of Brazil comprise one of these centres for the Neotropics. This study aims to verify the AoE of Pteridaceae in Brazil and examine whether the results obtained here are congruent with areas already delimited for other groups and whether there is spatial correspondence between the AoE and Conservation Units. To this end, a database was created with collection records of the 205 Pteridaceae species occurring in Brazil based on a review of herbaria. We analysed 23 815 records for 205 Pteridaceae species using Endemicity Analysis (NDM‐VNDM), selecting the fill and assumed parameters, and 1°, 2° and 3° grid‐cells. The consensus of 158 AoE, using different grid sizes, was calculated, and subsequently, generalized AoE were established. The Guiana Shield, southern Brazil, southeastern Brazil, and southeastern Bahia were considered generalized AoE. These areas correspond to those found for animals and angiosperms, and in previous studies with ferns. Furthermore, two areas, Acre and Mato Grosso do Sul, were recovered only on grids with 2° and 3°. It will be essential to conduct more research to confirm the persistence of both AoE (Acre and Mato Grosso do Sul), especially after expanding sampling. Most endemic species distribution points occur outside protected areas, demonstrating an alarming situation regarding the conservation of these taxa. In addition, fern distribution data could (and should) be used in conservation practices, programmes and policies, given that they are good ecological indicators and that the distribution of ferns may not reflect that of angiosperms and animals.

The Tropical Andes region harbors highly significant and threatened biodiversity areas. However, due to its misidentification, conservation initiatives in these regions are limited and need more substantial support. Identifying Important Plant Areas (IPAs) offers a valuable methodology for establishing conservation priorities, a particularly complex task in a mega-biodiverse region such as the Andean tropics. Due to its iconic recognition and conservation value, this study focused on the Espeletiinae subtribe (Asteraceae) as a reference group, and we compiled species distribution data for 138 taxa from 5,560 georeferenced records. Using the IPA, we divided the study area into 220 Units of Analysis (UA) represented by 10 × 10 km plots. Refined distribution areas, incorporating richness, threatened species, and ecosystem-based richness distributions, were analyzed using newly generated maps. Most UAs were concentrated in Colombia's Eastern Cordillera, extending into Venezuela. Our analysis identified 176 UAs using sub-criterion cA1 (with 59 species) and 51 UAs using sub-criterion cB (with 76 species). We classified 11 UAs as high-priority, 58 as medium-priority, and 143 as low-priority, highlighting the IPAs that require focused conservation efforts. Key findings from our study include: i) the first regional-level application of IPA methodology; ii) the potential of implementing criteria A and B to support global biodiversity recovery targets; and iii) the suitability of Espeletiinae as a focal group for systematic conservation planning in the region. Accordingly, we consider that our results establish a spatial planning procedure and analytical tool for decision-makers to guide conservation management and actions across the tropical Andean region.
