Sandy coastal plain vegetation (Restinga) is composed of communities of plants that grow on Quaternary Neosols along the entire extension of the Brazilian coast. The state of Piauí has a coastal extension of 66 km and is entirely located in the semi-arid zone of Northeastern Brazil. This study catalogued the phanerogam species found along the coast of the state of Piauí, the data of which was compiled from surveys in online databases and literature, and herbarium collections. A total of 363 species distributed among 235 genera, and 74 families were identified. The families with the greatest number of species included Fabaceae (108 species), Euphorbiaceae (19), Amaranthaceae (13), Apocynaceae (12), Cyperaceae (12), Rubiaceae (12), Bignoniaceae (11), Malvaceae (11) and Poaceae (11) and represent over 57.6% of the species collected. Approximately 87% of the species were common to other restinga areas in Northeastern Brazil, and ca. 13% were restricted to the coast of the state of Piauí.

Order Ceratiomyxales, which belongs to subclass Ceratiomyxomycetidae, includes the exospore bearing Myxomycetes, solely comprising family Ceratiomyxaceae and genus Ceratiomyxa, with four species. Based on the literature, on herbarium collections, and on recent surveys carried out by the authors in different states and ecosystems, it was possible to determine the occurrence and distribution of C. fruticulosa (cosmopolitan),C. morchella and C. sphaerosperma (predominantly tropical or subtropical) in northeastern Brazil. Species descriptions and illustrations are presented, as well as a map of their geographical distribution in eight of the nine states of Northeast Brazil. This order is being recorded for the first time for the state of Sergipe. Ceratiomyxa morchella and C. sphaerosperma are being cited for the first time for the state of Paraíba.

Breeding of goats and sheep is an important activity in northeast Brazil, contributing to economic and social development of this region. Thus, the objective of this study was to characterize goat and sheep rearing and breeding in the central-western region of the State of Paraíba, northeast Brazil. The study area included Borborema and mesoregions of the backlands of the state, represented by 127 municipalities in an area of 38.293 km2, with density of goats and sheep at 12.9 and 8.27 head/km2, respectively. A total of 62 farms belonging to five municipalities of the Borborema mesoregion and four municipalities of the Sertão mesoregion were surveyed. Epidemiological surveys were conducted in the farms, and questionnaires sought information on the economic, productive, and social aspects of the farm owners and the farms. The results allowed the classification of goat and sheep production systems in the semi-arid Paraíba as a family system and of subsistence, for farmers’ own consumption and for local trade, with low technology use and herds with up to 100 animals. The farmers’ level of education was low, and the investments and technical assistance for the development of breeding activity in the region were insufficient and/or inadequate. Thus, it was essential to conduct an economic study on the farms to assess the actual economic and financial status of breeding activity and the subsequent returns. It is suggested that these aspects be taken into account when planning livestock development policies, especially in terms of finance and technical assistance, as well as in the implementation of strategies to control commonly occurring diseases in the region, aimed at combating agents, environmental control, and protection of susceptible livestock.

The current work provides a new state record of the snake Chironius carinatus (Linnaeus, 1758) based on two specimens collected in the Atlantic Forest of Paraíba state, northeastern Brazil. This species occurs in the Amazon and Atlantic Forests. The new records fills in a gap in the species’ distribution on the Brazilian coast. In Paraíba, C. carinatus occurs in sympatry with two other Chironius Fitzinger, 1826 species, C. flavolineatus Jan, 1863 and C. exoletus (Linnaeus, 1758).

This study provides the first record of the exotic invasive bivalve Isognomon bicolor for the State of Paraíba, Northeastern Brazil. It has been found to occur in at least twelve coastal reefs along the coast. We also present its first record for the State of Alagoas and new record localities for the States of Rio Grande do Norte and Pernambuco, including its occurrence in hypersaline estuaries. From these records the distribution range of I. bicolor has been expanded to the littoral region of Northeast Brazil, where this invasive species seems well established.

The state of Paraiba is one of those with the most degraded Caatinga that presents the large gap of knowledge concerning the mammal fauna. Mammals are among the taxa most affected by this. In this sense, we evaluated non-volant mammals’ richness and composition between March 2013 and February 2020 in a Caatinga fragment (121 ha). We used active search (336 hours) and camera traps (1,200 night traps). We recorded 20 species, including four threatened ones. Carnivora was the most representative order (7 species), followed by Rodentia (4 species). The richness of non-volant mammals found represents 35.6 % of the total number of such species in the Caatinga. This species richness is greater than that found in other studies in the state. The presence of these mammal species was mainly due to the recovering vegetation that resulted from the great planting effort and also due to cessation of hunt, cattle and sheep breeding that had existed on the farm for over thirty years. Our findings highlight the importance of this particular reserve due to the large number of species registered.

A total of 272 species of brachyuran crabs are reported from marine and estuarine environments in northern and northeast Brazil. The checklist is derived from the literature published from 1847 to 2008, and includes all species that have been reported at least once from the study area. It is also partially supported by material deposited in the crustacean collection of the Departamento de Oceanografia, Universidade Federal de Pernambuco, city of Recife, Brazil (DOUFPE). The families containing the highest number of species in northern and northeastern Brazil are Majidae (31), Portunidae (22), Epialtidae (20), Panopeidae (20), and Xanthidae (18). The remaining species are distributed in 39 families. The analysis of the distribution of the species in the region, allows for identification of four patterns of longitudinal distribution (western Atlantic, Amphi-Atlantic, Amphi-American, and circumtropical species) and, in the western Atlantic, six patterns of latitudinal distribution (Virginian, Carolinian, Antillean, Central-South American, Boreal, and Endemic). Two non-indigenous species have also been reported. Most of the species represented in northern and northeastern Brazil have Antillean (94 species; 34.5%) and Carolinian (75 species; 27.6%) pattern of distribution.

Inselbergs are rocky environments that support a unique flora distinct from that of the surrounding area. The objectives of this work were to conduct a floristic inventory of an inselberg in the semi-arid region of Northeast Brazil, and to investigate the relationship between its flora and the flora of the surrounding area. The following questions were addressed: is the species richness comparable to other inselbergs in northeastern Brazil; is the floristic composition of the inselberg more similar to other inselbergs or to the surrounding Caatinga vegetation; and do the similarities in the floristic composition of inselbergs depend on the distance between them? This work documents 201 species in 62 families. Cyperaceae (28 spp.), Euphorbiaceae (19), Poaceae (15), Orchidaceae (11) and Bromeliaceae (9) are the most species-rich families. On the inselberg the plants are distributed in islands found on exposed rock, in fissures and in depressions in the rock. Variations in species richness in the region were assessed by comparison of floristic inventories conducted in other inselbergs of the semi-arid region with those of this study. The flora of the inselberg under investigation is more similar to the flora of other nearby inselbergs than to the vegetation of the surrounding semi-arid region.
