“…The area of southeastern Bahia has been interpreted as a refuge (the called “Bahia refuge”) for forest biodiversity, since the area presented climatic stability, even during the driest climatic phases (at the LGM; Mori et al., 1983; Rocha et al., 2005; Carnaval and Moritz, 2008; Carnaval et al., 2009; Matos et al., 2010; Ribeiro et al., 2011; Coelho and Amorim, 2014; Ostroski et al., 2020; Rojas‐Padilla et al., 2020). This refuge would be located between the São Francisco and Doce rivers (Carnaval and Moritz, 2008; Hoffmeister and Ferrari, 2016; Menini‐Neto et al., 2016).…”

“…For ferns, Matos et al. (2010) suggested connections between southeastern Bahia and the mountains of south and southeastern Brazil. This can be seen in the species Adiantopsis alata (occuring in southeast Bahia, Minas Gerais and Espírito Santo states), Adiantum discolour and A. tetragonum (both in southeastern Bahia and Espírito Santo states), and Pteris limae (southeastern Bahia, Espírito Santo and Rio de Janeiro states).…”

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.

Insect herbivory can be an important selective pressure and contribute substantially to local plant richness. As herbivory is the result of numerous ecological and evolutionary processes, such as complex insect population dynamics and evolution of plant antiherbivore defenses, it has been difficult to predict variation in herbivory across meaningful spatial scales. In the present work, we characterize patterns of herbivory on plants in a species‐rich and abundant tropical genus (Piper) across forests spanning 44° of latitude in the Neotropics. We modeled the effects of geography, climate, resource availability, and Piper species richness on the median, dispersion, and skew of generalist and specialist herbivory. By examining these multiple components of the distribution of herbivory, we were able to determine factors that increase biologically meaningful herbivory at the upper ends of the distribution (indicated by skew and dispersion). We observed a roughly twofold increase in median herbivory in humid relative to seasonal forests, which aligns with the hypothesis that precipitation seasonality plays a critical role in shaping interaction diversity within tropical ecosystems. Site level variables such as latitude, seasonality, and maximum Piper richness explained the positive skew in herbivory at the local scale (plot level) better for assemblages of Piper congeners than for a single species. Predictors that varied between local communities, such as resource availability and diversity, best explained the distribution of herbivory within sites, dampening broad patterns across latitude and climate and demonstrating why generalizations about gradients in herbivory have been elusive. The estimated population means, dispersion, and skew of herbivory responded differently to abiotic and biotic factors, illustrating the need for careful studies to explore distributions of herbivory and their effects on forest diversity.

“…With the exception of Schneider and Schmitt (2011), few studies have analyzed the vertical distribution of epiphytes on tree ferns, which limits our knowledge of how distinct strata and height affect the patterns of epiphytic distribution in this group of hosts. Even though all ecological categories of epiphytes may be found on tree ferns (Blum et al, 2011), quantitative studies about epiphytes on these hosts are uncommon in the subtropical Atlantic Forest, with only a few published records (Gasper & Sevegnani, 2010; Matos et al, 2020; Schmitt et al, 2005; Schmitt & Windisch, 2010; Schneider & Schmitt, 2011). Even more uncommon are studies that characterize accidental epiphytism in (sub)tropical forests.…”

Neglected epiphytism: Accidental epiphytes dominate epiphytic communities on tree ferns in the Atlantic Forest

Vascular epiphytes and tree ferns constitute an important part of the Atlantic Forest structure. We characterized vascular epiphyte communities on two tree fern species (Alsophila setosa Kaulf. and Cyathea phalerata Mart.) including accidental epiphytes (i.e., species that are usually terrestrial, without necessarily completing their life cycle as an epiphyte), which have been overlooked in many previous studies. We aimed to understand epiphytism in terms of distribution, diversity, community composition, and host attributes that affect the richness and abundance of accidental epiphytes. Despite the great species richness of accidental epiphytes, they were—in contrast to true epiphytes—generally low in abundance and heavily represented by singletons and doubletons. We did not identify a difference in accidental epiphytic diversity and composition between host species, implying that both host species provide similar habitats for accidental epiphytes—although some epiphytic species showed a preference for a specific host species and/or stratum. Epiphyte richness and abundance were positively associated with a codependence of host surface area and moisture content, but only for accidental epiphytes. Our study illustrates the importance of two tree fern species as epiphyte hosts in the rainforest understory. It also shows that, although frequently overlooked, accidental epiphytism can be common in the understory of tropical forests and a phenomenon that merits further study in this region. Abstract in Portuguese is available with online material.
