... Part of the northern Atlantic Forest is composed of a collection of smallto medium-sized patches of tropical moist forest that cover the slopes of isolated plateaus rising above the dry forests of the Caatinga. These are the "Caatinga moist forest enclaves" or, as they are locally known, as "Brejos de Altitude" or "Brejos Nordestinos" (Andrade-Lima 1982), and harbor endemic species of several plants and animals (Andrade-Lima 1982;Borges-Nojosa and Caramaschi 2003;França et al. 2020;Pessoa and Alves 2015). These moist forest enclaves are very peculiar in biodiversity terms, especially when compared to the rest of the Atlantic Forest, as their biota shows a mixture of Amazonian elements as well as others from the Atlantic Forest of southern and southeastern Brazil, amidst a matrix of semiarid vegetation (Andrade-Lima 1960. ...
Spiders are a common and supposedly well-known group of animals that can be found in a large variety of microhabitats, including human constructions. These organisms represent a highly diversified taxon, with significant ecological and human importance. Although spiders are among the most diversified groups of arthropods, the knowledge regarding their diversity patterns suffers from strong biodiversity shortfalls. In Brazil, the distribution of spider records is strongly aggregated spatially, which can be explained by a museum effect, and the effect of easy-to-sample localities. The highest number of records is found in Atlantic Forest, and therefore, this biome has the highest number of recorded spider species and endemic species. However, these records are concentrated in a few regions. The Northern Atlantic Forest, located north of the São Francisco River, is one of the least sampled portions of the biome. This chapter presents a comprehensive overview of the diversity and distribution patterns of spiders in this part of the Atlantic Forest considering data of orb-weavers (superfamily Araneoidea) and daddy long-legs (family Pholcidae) spiders. We produced maps showing the spatial variation of the distribution records in order to evaluate the sampling effort, species richness, beta-diversity, and areas of endemism. The spider fauna in Northern Atlantic Forest is known from 212 records of 70 species, and 19 of those are endemic. The present results evidence and corroborate the hypothesis of strong biodiversity shortfalls regarding the spider fauna from this part of the Atlantic Forest. These results support the striking need to stimulate the development of more scientific studies and to allow a proper recognition and conservation of this fauna.KeywordsAraneoideaBiodiversity shortfallsBiogeographyDistribution recordsPholcidaeSpatial analysis

Dung beetles are sensitive to environmental quality, therefore being excellent bioindicators and are being used to assess the effects of habitat transformation. These beetles are detritivores, thus contributing to the environment by cycling soil nutrients, aerating the soil, and performing secondary seed dispersal. In this chapter, our primary goal is to compile from the scattered literature information on the dung beetle species already identified in the Atlantic Forest north of the São Francisco River. We provide information on the diversity, biology, and conservation status of dung beetle species already evaluated, as well as point out the gaps in our knowledge and regions that still lack surveys. Our literature review found 6 tribes, 23 genera, and 89 species of dung beetles, comprising data from Atlantic Forest, Restinga and Brejos de Altitude ecosystems in the states of Rio Grande do Norte, Paraíba, Pernambuco and Alagoas. Although information on the diversity of dung beetle in the northern Atlantic Forest is still limited in terms of territorial extension, its importance and fragility are undeniable. The number of endemic species is significant, thus making this area and its beetle fauna a priority for conservation.KeywordsScarabaeidaeScarabaeinae distributionEndemismBrejo de AltitudeRestinga

Distribution, ecology and conservation status: It occurs in the West Indies, southern North America (Florida, Mexico), Central America and tropical South America (Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Paraguay, Peru, Uruguay, and Venezuela) (Azevedo et al. 2014). In Brazil, it occurs in the Amazon, Atlantic Forest and Cerrado, all over the country (Azevedo et al. 2014;Pessoa et al. 2015). It is being registered here as occurring in a tabuleiro forest in Rio Grande do Norte for the first time, where it was observed growing on white sandy soils. ...
Lowland forests, also known as tabuleiro forests, are the predominant phytophysiognomy in the Atlantic Coastal Forest in northeastern Brazil. We inventoried the Orchidaceae present in the northern section of those forests, from the state of Rio Grande do Norte until the southern region of the state of Pernambuco. We examined specimens from seven regional herbaria and undertook field expeditions to four conservation units in the region. A total of 65 species belonging to 36 genera and to subfamilies Epidendroideae (44 species), Orchidoideae (16), and Vanilloideae (5) were identified. The most diverse genera are Epidendrum e Habenaria, with eight and seven species, respectively. Native species represented 96 % of the total observed, with 27 % being endemic to Brazil. Epiphytic (35) and terrestrial (27) species predominated; only three species are hemiepiphytic. We registered 14 new records of species for Rio Grande do Norte, two for Paraíba, and one for Pernambuco. Diagnoses of genera and species, as well as an identification key, data on geographic distribution, taxonomic and ecological comments, conservation status, and photos of the species are provided.

We report the first record of Eurystyles actinosophila (Barb.Rodr.) Schltr. and the genus Eurystyles Wawra (Orchidaceae) in the Central-West region of Brazil. The species was found in the Brasília National Park, in Brasília, Distrito Federal, in the core region of the Cerrado. We also undertook a survey of collection sites in Brazil for species of Eurystyles and Lankesterella Ames, which together form the epiphytic clade of Spiranthinae, in order to create an updated distribution map. Previously identified only in the Atlantic Forest and Pampa, we note that some species of these two genera also occur in the Cerrado and Caatinga domains.
... Geographic Distribution and Ecology-Eugenia petaloidea is restricted to submontane forests (to 700 m high) in Pernambuco state in the northern portion of the Atlantic Forest (Fig. 2). This area is known for its high species richness (Pessoa and Alves 2015b;Melo et al. 2016) and several recently described endemic species (Sothers 2003 Etymology-The epithet "petaloidea" refers to the two internal petaloid calyx lobes that are a diagnostic character for this species. ...
The hyper-diverse Eugenia with ca. 1050 species currently includes Calycorectes, which fits the morphological delimitation of the latter except its calyx lobes are fused in the bud and tear at anthesis. Previous phylogenetic reconstruction demonstrates a single evolutionary event of calyx fusion in Eugenia. A new species, Eugenia petaloidea, found in remnants of submontane Atlantic Forest in northeast Brazil is morphologically uniquewith two external fused calyx lobes that split at anthesis and two internal free and petaloid calyx lobes. Only a few other Eugenia species share this condition, and Eugenia petaloidea can be distinguished from those by the externally glabrous hypanthium. The phylogenetic placement of Eugenia petaloidea based on three DNA markers (ITS, ETS, and psbA-trnH) indicates that this is the second clade of Eugenia known to have a fused calyx, indicating fusion of the calyx to be a homoplastic condition. The new species is here described, illustrated, and assessed according to IUCN criteria.

The fact that only three populations from widely separated localities have been documented despite extensive floristic studies in the Atlantic Forest (e.g. Fraga & Peixoto, 2004;Cunha & Forzza, 2007;Menini-Neto et al., 2007;Abreu et al., 2011;Pessoa & Alves, 2011Marinho & Azevedo, 2013;Moreira et al., 2014;Pessoa & Alves, 2015;Rego & Azevedo, 2017) suggests that the species is quite rare and/or absent from much of the region. ...
This study provides new records of Macroclinium roseum, a species originally described from the Brazilian state of Rio de Janeiro, and which appears to be endemic to the Brazilian Atlantic Forest. The new records expand the documented distribution of the genus in the Atlantic Forest to the states of Espírito Santo and Alagoas. Previous reports of the species from the Amazon appear to have been made in error. The collections from Espírito Santo and Alagoas, made in 2005 and 2017, respectively, are the first collections of M. roseum since its description in 1882. An updated description and distribution map for the species are provided, along with photographs, assessment of the species’ conservation status, and a key for the identification of the Brazilian species of Macroclinium. A lectotype and epitype are designated for M. roseum.

A new species of Maranta subg. Maranta, M. gigantea, is described and illustrated. This is known from the submontane Atlantic Forest in the states of Pernambuco and Alagoas (Brazil). Based on the zingiberoid growth form it is morphologically similar to M. anderssoniana and M. zingiberina, differing mainly in the shape of the leaf blade (lanceolate to oblong or ovate respectively vs. narrow-lanceolate) and number of calli in the callose staminode (one prominent callus vs. two prominent calli). It is further differentiated from M. anderssoniana by being larger plants (up to 1.8 m tall vs. up to 1.0 m tall), with a tomentose leaf sheath (vs. sericeous), larger corolla tube length (9−12 mm long vs. 5−6 mm long), asymmetrically elliptical corolla lobes (vs. asymmetrically oblong) and larger outer staminodes (minor 12−15 × 6.5−8 mm vs. 10−11 × 5.5−6 mm and major 13−16 × 8.5 × 10.5 mm vs. 10−12 × 8−9.2 mm). Due to its narrow distribution, it is classified as critically endangered.

... In this sense, the family Bromeliaceae has 17 genera and 41 species occurring in the area which represents 85% of the genera and 40% of the species recorded for Pernambuco (Forzza et al. 2015). In turn the Serra do Urubu supports 61.5% of the genera and 39% of the species of Orchidaceae occurring in the state of Pernambuco (Barros et al. 2015;Pessoa and Alves 2015b) and harbors 26.4% of all species of Myrtaceae recorded in the state. Other families of less floristic relevance also have a significant portions of their biodiversity in Pernambuco preserved in the Serra do Urubu. ...
A list of angiosperms from Serra do Urubu, a montane forest area in the state of Pernambuco, is here provided. Based on 14 botanical expeditions and material deposited in herbaria, 832 taxa belonging to 442 genera and 118 families have been recorded in this area, with about 90% of the taxa identified to species level. The richest families are Orchidaceae (86 spp.), Fabaceae (51 spp.) and Rubiaceae (42 spp.). Miconia and Solanum (14 spp. each), and Psychotria (13 spp.) are the richest genera. About 15% of the recorded species are endemic to the Atlantic Forest, and another 10% are disjunct between this area and the Amazon Rainforest. The results indicate that the Serra do Urubu is one of the richest areas in terms of number of species of the Atlantic Forest in the Northeast, and corroborates the Pernambuco Endemism Center.
