“…Similar results have been seen for other groups of organisms, such as diplopods (Iniesta et al., 2023) and angiosperms (Werneck et al., 2011; Eisenlohr et al., 2015; Alvez‐Valles et al., 2018). For the first group, the majority of species occur in areas that have not been designated as CU and do not have conservation policies in force (Iniesta et al., 2023). For the second group, less than a third of the endemic taxa occur in strictly protected areas, and there is a negative picture regarding the effective conservation of the group when the AoE are superimposed on CU (Werneck et al., 2011).…”

“…Several studies have verified similar AoE for the most varied groups of organism: angiosperms (Tabarelli et al., 2005; Quijano‐Abril et al., 2006; Murray‐Smith et al., 2008; Werneck et al., 2011; Fontoura et al., 2012; Buril et al., 2014; Leitman et al., 2015; Menini‐Neto et al., 2016; Colli‐Silva and Pirani, 2019; Pacifico et al., 2020; Florentín et al., 2022), arthropods (Hoffmeister and Ferrari, 2016), bees (Garraffoni et al., 2017), beetles (Silva and Vaz‐de‐Mello, 2020), birds (Silva et al., 2004), diplopods (Iniesta et al., 2023), harvestmen (Da Silva et al., 2015), hemipterans (Goldani and Carvalho, 2003), insects (Goldani et al., 2002), mammals (Costa et al., 2000; Dalapicolla et al., 2021), moths (Ferro and Melo, 2010), flatworms (Lago‐Barcia et al., 2020) and vertebrates (Tabarelli et al., 2005). Although there is a large overlap of these AoE, based on data from different groups of organisms, the limits of these areas are not perfectly concordant, which can be due to the particularities of each taxon.…”

“…In the second case, for grids of 1° we used 40% of the fill radius and 80% of the assumed radius; for grids of 2°, 20% of the fill radius and 40% of the assumed radius; and for grids of 3°, 10% of the fill radius and 20% of the assumed radius (following Narváez‐Gómez et al., 2022), and using the “edge proportions” option (Andrade‐Díaz et al., 2017; Ostroski et al., 2020; Silva and Vaz‐de‐Mello, 2020). The remaining parameters were common to the six analyses: grid origin point x = −75 000 and y = 5000 (Gomes‐da‐Silva and Forzza, 2021); heuristic searches with 1000 random seed; AoE with scores equal to (or above) 2.0 (Prado et al., 2015; Azevedo et al., 2016; Garraffoni et al., 2017; Alvez‐Valles et al., 2018; Gómez and Escalante, 2018; Colli‐Silva and Pirani, 2019; Silva and Vaz‐de‐Mello, 2020; Iniesta et al., 2023); 40% unique species (Pacifico et al., 2020; Silva and Vaz‐de‐Mello, 2020); and temporary saving of sets within 0.995 of the current score, with 100 repetitions. Finally, the flexible consensus (against any of the other areas) was used, with a cutoff value of 40% similarity in species (Casagranda et al., 2009; Ferrari et al., 2010; Aagesen et al., 2013; Andrade‐Díaz et al., 2017; Garraffoni et al., 2017; Gomes‐da‐Silva and Forzza, 2021; Narváez‐Gómez et al., 2022).…”

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.

A classe Diplopoda corresponde a cerca de 12.000 espécies nominais. Indivíduos desta classe estão associados a quase todos os estratos do solo, contribuindo de maneira eficiente para a ciclagem de nutrientes. Algumas espécies são consideradas pragas agrícolas, amplamente distribuídas atráves de atividades humanas. No Brasil, são conhecidas 12 espécies introduzidas, com grande parte dessas originarias da Ásia e difundidas principalmente na região sudeste do país. Dentre essas, destacam-se Oxidus gracilis (C.L. Koch) e Orthomorpha coarctata (Saussure) (Polydesmida, Paradoxosomatidae), registradas para quase todas as regiões do Brasil, e Trigoniulus corallinus (Gervais) (Spirobolida, Pachybolidae), de ocorrência para o Norte, Nordeste e Sudeste. No entanto, mesmo essas sendo amplamente distribuídas, nenhuma tem registro até o momento para o estado do Maranhão. Nesta perspectiva, o presente trabalho tem como objetivo registrar pela primeira vez no estado do Maranhão a ocorrência destas espécies a partir de coletas em áreas urbanas do município de Códo, região ao leste do estado, durante os meses de janeiro e fevereiro de 2023. De modo geral, os indivíduos foram encontrados enterrados em camadas mais superficiais do solo ou associados a poças de água próximas da serrapilheira. A região apresenta grande diversidade vegetal, mas sem nenhuma unidade de conservação formulada até o momento, além de sofrer atualmente com o avanço de atividades extrativistas e de Silvicultura, podendo acarretar a perda da diversidade biológica em áreas ainda quase que inexploradas em relação a fauna.

Somatic characters are shared by many Chelodesmidae groups, and generic placement and species identifications traditionally have been based on gonopodal morphology. Female genitalic characters have been largely neglected and are rarely photographed or illustrated. This is rather unfortunate as the morphology of female genitalia presents important characters and may be decisive for developing a more robust family classification. We describe the heretofore unknown female of Sandalodesmus araujoi (Schubart, 1946), previously known only from the male holotype collected in São Paulo, Brazil in December 1943; discuss the utility of female genitalic characters for species delineation in Sandalodesmus; and report the first case of a mass occurrence in the Chelodesmidae. While an attempt at a formal diagnosis of Sandalodesmus females based on genitalic characters is premature, the vulvar morphology of the three taxa examined in this study suggests that female genitalia are species-specific. Some characters (i.e., asymmetric valves, presence of digitiform projections and reduction of setae on the internal basal portion of the valves) are constant between the species, suggesting utility for generic-level delineation. Mass occurrences of millipedes are typically unpredictable and likely related to variations in environmental conditions and/or anthropogenic modifications of natural habitats. Although the mass occurrence of S. araujoi reported herein was only observed once, the event coincides with the mating period of millipedes during the rainy season in Brazil. On the other hand, the region where the species was found has been the target of intense urban development, including replacement of natural habitats with residential areas, which may have influenced its population dynamics.
