Biogeography of restinga vegetation in Northern and Northeastern Brazil and their floristic relationships with adjacent ecosystems

Abstract

Restinga formations are defined as the vegetation covering sandy coastal sediments deposited during the Quaternary period, regardless their physiognomy. They are usually characterized as areas of confluence between plant species associated with diverse phytogeographical domains. However, detailed floristic and biogeographic studies are still required to better define their distribution patterns, the origins of their plant species, and their biogeographical affinities. In this study, we investigate the floristic similarities among restingas in Northern and Northeastern Brazil and diverse ecosystems from different Brazilian phytogeographical domains (Caatinga, Cerrado, Atlantic Forest and Amazonia). We employed multivariate analyses to investigate differences in species composition and identify floristically similar groups. While sharing species with other ecosystems, restingas exhibit unique floristic composition, representing a coastal flora. Furthermore, the restingas of Northern and Northeastern Brazil are biogeographically subdivided according to previously recognized sectors of the coast of the country. These findings underscore the complex nature of restinga ecosystems, influenced by environmental factors such as geographic distance, geology and climate. These insights contribute to a nuanced understanding of the complex relationships between restingas and their surrounding ecosystems, facilitating informed conservation efforts in the face of escalating urban and industrial expansion along the Brazilian coast.

INTRODUCTION

A diverse array of vegetation types occurs along the Brazilian coastline, encompassing grasslands, savannas, and forests that grow on sandy coastal sites or muddy estuary areas (Ab’Saber 2001, 2006, Overbeck et al. 2022). The term “restinga vegetation” has been employed in both scientific literature and Brazilian legislation to refer to the plant cover on sandy substrates. However, its use has been inconsistent, leading to significant variations and generating discussions and controversies. Etymologically, the term “restinga” has a Luso-Brazilian origin (Souza et al. 2008), referring to the sandy sediments that were deposited in coastal zones after repeated processes of marine transgression and regression during the Quaternary period (Suguio & Tessler 1984). That term was later extended to the field of botany to describe the vegetation established on these sandy sediments (Flexor et al. 1984).

In a botanical context, restinga vegetation encompasses a set of plant communities associated with sandy coastal sites (Cerqueira 2000), such as those on beaches, movable, semi-fixed and fixed dunes, as well as coastal forests and savannas (Suguio & Tessler 1984). Rizzini (1997) broadened the term to include all vegetation complexes growing on Holocene sandy surfaces of marine origin, essentially classifying all the vegetation along the Brazilian coast as “restinga”. While the Radam Brasil project (developed between 1970 and 1985) significantly contributed to classifying Brazilian coastal plains and mapping vegetation types (Veloso & Góes-Filho 1982, Veloso et al. 1991, IBGE 2012), it has faced criticism for oversimplifying the diverse vegetation types occupying sandy coastal areas under a single category. As a consequence, even today, official maps and Brazilian legislation often disregard phytophysiognomic variation within coastal ecosystems, such as forest, savanna or open formations (Correia et al. 2020a), collectively referring to them as “restinga”, “vegetation under marine influence” or “restinga complexes” or “mosaics”. Despite this, restinga vegetation are complex formations that exhibit wide variation in physiognomy and distinct ecological conditions. These formations are exposed to stressful environmental conditions, including high temperatures, elevated salinity, nutrient-poor sandy soils, strong winds, and deep water tables (Almeida-Jr et al. 2009, Moro et al. 2015). However, the vegetation exhibits high adaptability to these conditions, with plants possessing physiognomic, anatomical and physiological adaptations that allow efficient utilization of resources, including obtaining nutrients from poor soils and withstanding salinity from marine aerosols (Lacerda 1984, Júnior & Cuzzuol 2009, Santos-Filho et al. 2013).

Few restinga species are known to be endemic, and most restinga plants can be found in other ecosystems and phytogeographical domains. Rizzini (1963), for example, suggested that most of the plant species growing in restingas originated in the Atlantic Forests, but several species also have their origins in other phytogeographical domains such as Amazonia, Cerrado, and Caatinga (Cerqueira 2000, Scarano 2002). Recent taxonomic studies, however, have identified new restinga endemic species in different regions of Brazil (e.g., Pacifico & Almeda 2020, Queiroz et al. 2020, Sodré et al. 2023), indicating that some of its floristic components are exclusive of coastal restingas vegetation.

Despite recent advancements (e.g., Neves et al. 2017, Massante & Gastauer 2023), the lack of comprehensive information regarding floristic composition of the restingas (Martins et al. 2008) makes their classification yet imprecise. Floristic inventories of restinga formations are less common as compared to inventories in other ecosystems of Amazonia, Caatinga, Cerrado, and the Atlantic Forest (Correia et al. 2020). Moreover, botanical studies focused on restinga have been unevenly distributed among the regions of Brazil. More recently efforts were made to enhance sampling in the Northern and Northeastern regions of country (e.g., Silva et al. 2010, Queiroz et al. 2012, Castro et al. 2012, Oliveira & Landim 2014, Fernandes & Queiroz 2015, Correia et al. 2020b, Araujo et al. 2020, Oliveira & Landim 2020). Nevertheless, there is still significant room for improvement in the geographical coverage of botanical surveys conducted in the restingas, with the most of publications concentrated in the Southern and Southeastern regions of Brazil (e.g., Assis et al. 2004, 2011, Scherer et al. 2005, Guedes et al. 2006, Martins et al. 2008, Lima et al. 2011, Marques et al. 2015, Júnior & Boeger 2015, Schlickmann et al. 2019, Silveira et al. 2022). Therefore, there is an urgent need for increased floristic studies in the least known Northern and Northeastern regions.

Considering the numerous knowledge gaps regarding the floras of restingas and the escalating degradation of coastal areas due to rapid expansion of urban and industrial areas (Rocha et al. 2007), a more profound understanding of these plant formations is needed to effectively inform conservation efforts. This study focuses on the biogeography of the restinga floras in the Northern and Northeastern regions of Brazil, where studies are scarce despite severe impacts from anthropic activities. We compiled several floristic publications focused in the restingas of Northern and Northeastern Brazil, comparing their species compositions with those of the other environments within Amazonia, Caatinga, Cerrado and the Atlantic Forest phytogeographical domains. Our comparative analysis aims to determine whether the restingas of the region exhibit floristic identity (e.g., restinga sites are more similar to each other regardless the distance separating them) or align more closely with their surrounding vegetation types.

MATERIALS AND METHODS

Datasets

We conducted a literature search for floristic surveys of restinga sites in Northern and Northeastern Brazil, as well as non-restinga environments of Brazilian phytogeographical domains (Amazonia, Caatinga, Cerrado, Atlantic Forests), using the Google Scholar, Scielo and Science Direct bibliographic platforms. We considered studies published in scientific journals, books, dissertations and theses. The bibliographic searches employed keywords in both Portuguese and English, including “floristics” and “restinga”, along with the names of the Northern and Northeastern coastal states of Brazil (in order from north to south): Amapá, Pará, Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, and Bahia (e.g., “floristics, restinga, Amapá”). We also searched for floristic inventories in non-coastal formations of Brazilian phytogeographical domains, using as keywords for each domain (Amazonia, Caatinga, Cerrado or Atlantic Forests) along with the words “floristics” and “vegetation” (e.g., “Amazonia, floristics, vegetation”). Studies were then selected based on their geographic proximity to our restinga dataset.

Only floristic surveys that included plants from all strata and all habits (herbs, climbing plants, shrubs and trees) were considered. Surveys focusing solely on a single botanical family or specific habits (e.g., only woody plants or only climbing plants) were excluded. The limited number of studies from Amazonia domain (six) largely reflects the scarcity of comprehensive inventories including all vegetation strata as most studies in the region focused on the arboreal stratum. Our final dataset comprised 31 floristic surveys of restinga areas in Northern and Northeastern Brazil, 15 in the Cerrado, 12 in the Caatinga, 13 in the Atlantic Forests, and six in the Amazonia (Appendix 1, Figure 1).

The dataset includes studies of different phytophysiognomies of restinga vegetation, following the classification proposals of authors such as Bastos et al. (1995), Santos-Filho et al. (2010), Moro et al. (2015) and Lima et al. (2017). The concept of restinga used in this study therefore encompasses formations located close to the ocean, growing on Quaternary sandy substrates. These are distinct from vegetation on coastal tablelands (matas de tabuleiro), primarily differing in geological age as the vegetation on coastal tablelands is established on Tertiary surfaces (Sousa & Santos-Filho 2020), but a few studies included areas of restingas and coastal tablelands together without separating their floristic lists.

We used the Flora do Brasil 2020 database to standardize and clean our taxonomy dataset. We first used Flora do Brasil 2020 to check the validity of all names in our dataset, replacing synonyms and misspelled names for the accepted species. In cases presenting infraspecific category (e.g., subspecies or variety), we considered only the species category. Taxa identified to genus or family level, along with those with imprecise identifications (affine and confer) were excluded. Exotic species, according to information of Flora do Brasil 2020, were also excluded as their occurrence is not pertinent to biogeographic studies. Finally, we also excluded species restricted to mangrove vegetation as this environment has quite distinct conditions of those in the restingas. Our final database comprised 77 sites and 5,857 species, used to build a presence/absence matrix of species per area (supplementary material at: <https://doi.org/10.6084/m9.figshare.24002199.v1>).

Biogeographic analyses

The floristic similarities between the areas was compared with cluster analysis using the algorithm Unweighted Pair Group Method with Arithmetic Mean (UPGMA) and the Sorensen similarity index (Bray-Curtis). Cluster analyses are a set of methods that aim to separate objects into distinct groups based on the number of features they have in common. For biogeography or ecology, we can separate sites with distinct species composition into groups where sites with more shared species in common are grouped into clusters distinct from clusters with sites with less species in common (see Legendre & Legendre 2012, Wildi 2010). Based on the proportion of shared species between two sites, they receive a similarity value (in our case using Sorensen similarity index) for the pair, were sites with a value of 1 share all species between them and sites with similarity of 0 do not share any species (Legendre & Legendre 2012). The general quality of the cluster analysis was evaluated by the cophenetic correlation, that express to what extent the graph correlates with the complex, multivariate data that is being simplified for plotting (Legendre & Legendre 2012).

We also conducted an ordination analysis using Nonmetric Multidimensional Scaling (NMDS) with the presence/absence matrix and the Sorensen index (Legendre & Legendre 2012). The multivariate ordination analyses are a group of methods that represent multivariate objects (in our case multiple sites with thousands of species) based on the general similarity (proportion of shared species) between them (Koleff et al. 2003, Legendre & Legendre 2012). NMDS method represent sites (floristic studies) as points on a graph. The method compares the similarity between all pair of sites based on the number of shared species between each pair of sites and organizes all sites on a graph based on the general similarity between sites (Legendre & Legendre 2012, Wildi 2010). Sites that are more similar are placed closer to other similar sites, while sites with distinct plant communities are positioned far apart in the graph. We have labeled the different habitats (restinga, Caatinga, Cerrado, etc) with different symbols to evaluate in the graph how the flora of each habitat is similar or different from the flora of other habitats being compared. Both group and ordination analyses were performed using Past 4.13 software (Hammer et al. 2001). The matrix used in the multivariate analyses is available in our supplementary data.

We also used Venn Diagrams to compare the overlap of floras among different floristic groups using the Bioinformatics & Evolutionary Genomics platform (http://bioinformatics.psb.ugent.be/webtools/Venn/), which uses the software Venny 2.1. This aimed to further investigate which species are shared among different vegetation types.

RESULTS

The examination of the similarity indices among restinga and non-restinga formations of diverse Brazilian phytogeographical domains revealed the emergence of five floristic groups (A – E) (Figure 2). These groups exhibited high coherence with their respective vegetation types, and distinct vegetation types clustered for the Cerrado, Caatinga and Amazonia, with restinga vegetation mixing with the flora of the Atlantic Forest in groups B and C. Nevertheless this result, most of restinga vegetation formed a large group, from restingas in Amazonia (Pará state), to restingas in the semiarid coast bordering the Caatinga (Ceará and Piauí states) and restingas bordering the humid Atlantic Forest (Rio Grande do Norte, Paraíba, Pernambuco, Sergipe and Bahia states). This cluster of restinga sites grouped with a few non-restinga in the Atlantic Forest of Paraíba and Pernambuco. And this larger cluster, grouped to other Atlantic Forest sites (with a small similarity, of less than 0.1). Group A comprised solely Caatinga sites. Group B consisted of restingas in Northern and Northeastern Brazil, along with a few non-restinga sites of the Atlantic Forest domain. Group C comprised areas of coastal and non-coastal Atlantic Forest formations in the states of Bahia, Pernambuco and Espírito Santo, along with a single restinga site in Bahia. Group D included solely Cerrado vegetation sites in the state of Ceará (Chapada do Araripe) and central Brazil (in the Federal District and the states of Goiás and Minas Gerais). Group E was formed by Amazonia (upland and seasonally flooded forests) in the states of Amazonas and Pará. The cophenetic correlation coefficient of grouping was 0.8875, suggesting the analysis is robust.

The formation of these groups was further corroborated by the NMDS analysis (Figure 3). In that ordination, sites within the investigated phytogeographical domains maintained consistent grouping pattern. Greater proximity is only observed among restingas and sites belonging to other environments in the Atlantic Forests (stress 0.2059, considered a good representation of the dataset in a reduced space).

Additional analyses using Venn Diagrams illustrated species overlap among the restingas and other environments within nearby Brazilian phytogeographic domains. The results highlighted the influence of the surrounding phytogeographic domains, especially the Atlantic Forest, which shared the largest number of species (651 spp.) with the restingas of Northern and Northeastern Brazil, followed by the Caatinga (331 spp.), Cerrado (297 spp.) and Amazonia (272 spp.) (Figure 4).

DISCUSSION

The floristic groups identified in our analyses largely reflect the floras of the respective phytogeographical domains to which they belong, and the restinga sites do not align to any specific domain. Restingas exhibited a higher number of shared species with formations within the Atlantic Forest – and some Atlantic Forest sites grouped with restinga sites, whereas one restinga site located in Bahia grouped with a mostly Atlantic Forests cluster. However, the majority of restinga sites formed a singular group (group B), displaying low similarity with other vegetation types.

Group B, while dominated by restinga sites, also included some non-restinga sites within the Atlantic Forest domain. The overall similarity within this group was relatively low (< 0.3), although subgroups displayed Sorensen values exceeding 0.6 (Figure 2). This overall low value is attributed to the limited number of shared species, in most cases, widely distributed along the coast of Brazil and in more interior formations. These results underscore the singular floristic composition of different restinga sites, reflecting the environmental heterogeneity of Brazilian coastal regions (Magnago et al. 2011, Correia et al. 2020a). Although some restinga sites grouped with other environments within the Atlantic forests, the fact that most restinga sites grouped together highlights restingas unique floristic identity. Notably, the presence in our dataset of species unique to the restinga, such as Bacopa cochlearia, Canavalia rosea, Cyperus pedunculatus, Duguetia restingae, Eugenia luschnathiana, Jacquinia armillaris, Myrcia restingae (see list of species from Venn diagrams that occurred only in restingas in the supplementary material) reinforces the presence of various species restricted to the restinga habitat.

Despite restingas singular identity, putative connection with other formations within the Atlantic Forest should be acknowledge, though in need of more scrutiny. Indeed, previous authors have highlighted the influence of the Atlantic Forest on the patterns of diversity and composition of restinga communities (Rizzini 1963, Fernandes & Queiroz 2015). Our analyses revealed that, regarding the restingas of the Northern and Northeast Brazil, floristic links with the Atlantic Forest may be an outcome of environmental similarities. For example, the non-restinga Atlantic Forest sites (Figure 2) that clustered with the restinga dominated Group B are described as semi-deciduous seasonal forests growing on coastal plateaus dating to the Tertiary Period (Pereira & Alves 2007, Leite et al. 2007, Amazonas & Barbosa 2011, Barbosa et al. 2011, Pinto et al. 2019), meaning they are subjected to regular water-deficit as that experienced in restinga formations due to the low water-retention capacity sandy soils (Souza et al. 2008).

Restinga and their vegetational mosaics

Our findings support the concept of organizing restinga vegetation in accordance with previously established compartmentalization of the Brazilian coast into distinct sectors (Villwock et al. 2005). Subgroups within Group B, for example, closely correspond to the Amazonian Northern sector (encompassing the states of Pará and Maranhão), the semiarid Northeastern sector (covering the states of the states of Piauí, Ceará and the northern region of Rio Grande do Norte), and the Atlantic Forest sector (spanning along the southern coast of Rio Grande do Norte State and Pernambuco, Alagoas, Sergipe and Bahia). This pattern suggests that variations in the floristic compositions of restingas in Northern and Northeastern Brazil may be predominantly influenced by factors associated with climatic and geomorphological variations (see Villwock et al. 2005, Diniz & Oliveira 2016).

Climate and geographic distance, along with additional parameters such as the influence of surrounding phytogeographical domains (Cerqueira 2000, Scanaro 2002, Fernandes & Queiroz 2015, Silva & Souza 2018) may also significant factors influencing the levels of floristic similarity among restinga sites. Plants inhabiting the restingas established over coastal plains of the Amazonian northern sector, with large extensions of estuary zones (Lima & Almeida-Jr 2018), for example, are exposed to higher amounts of rainfall. Plats inhabiting the Tertiary-Quaternary sandy plains along the semiarid Northeastern coast (Silveira 1964, Moro et al. 2015), on the other hand, tend to experience drier climatic conditions (Nimer 1972, IBGE 2002, Castro et al. 2012, Soares et al. 2021). These environmental differences partially explain why the restingas along the coasts of Pará and Maranhão are mostly dominated by species typical of wetter environments, such as Abarema cochleata, Calycolpus goetheanus, Entada polystachya, Myrcia cuprea and Rhabdadenia biflora (Cabral-Freire & Monteiro 1993, Amaral et al. 2008, Serra et al. 2016, Lima & Almeida-Jr 2018), whereas restingas areas in the states of Ceará, Piauí and the northern region of Rio Grande do Norte (including the municipalities of Rio do Fogo and Natal) are mostly populated by species typical of those seasonal environments, such as Anacardium occidentale, Cereus jamacaru, Croton blanchetianus, Curatella americana, Himatanthus drasticus, Mimosa ophthalmocentra, Piptadenia retusa, Stryphnodendron coriaceum and Sarcomphalus joazeiro (Castro et al. 2012, Lima & Almeida-Jr 2018).

Within the Atlantic Forest coastal sector, two subgroups were identified: one in the northern portion of the Atlantic Forest coast of Brazil and another in the southern portion of that area that includes the states of Sergipe and Bahia (north of the Todos os Santos Bay). Notably, the restinga site located to the south of Todos os Santos Bay in Bahia State (Fernandes & Queiroz 2015) clustered with non-restinga environments of the Atlantic Forest (Group C). Once again, this distinction in floristic composition seems to be explained by distinctive climatic conditions, the coastal region north of Bahia State experiences a seasonal tropical climate with well-defined dry seasons, whereas the southern portion of the state is under a humid tropical climate without dry season (Oliveira-Filho & Fontes 2000, Peel et al. 2007, Alvares et al. 2013).

CONCLUSIONS

Restingas are complex ecosystems that show diverse floristic composition along its long geographical extension. Our work adds to the knowledge of the restinga formations in Northern and Northeastern Brazil, regions largely neglected by previous studies. We showed that, despite the influence from surrounding ecosystems, the restingas of the regions present some degree of floristic singularity and form their own floristic cluster. The variation in floristic composition within the restinga cluster is linked factors such as geographic distance, geomorphological and climatic variables.

Our analyses revealed that the flora of the restinga of Northern and Northeastern Brazil are distinct from other ecosystems in different phytogeographic domains and that they are subdivided according to previously recognized sectors of the Brazilian coast (Villwock et al. 2005). These results suggest that current classification adopted by the official Brazilian authorities (e.g., IBGE 2012) is insufficient due to their oversimplification (e.g., Veloso et al. 1991, IBGE 2012). Finally, our study highlights that future biogeographic investigations are critical for understanding restinga plant species composition, in order to provide information relevat for effective conservation and decision making.
