This specimen, a female, was collected from a 4-meter depth, had a partial total length of 249.6 mm and weighted 173 g. This is the second report of P. monodon off the coast of Rio Grande do Norte, 11 years after the first record, which suggests an ongoing southward expansion of this species in northeastern Brazil. 2015-07-01T00:00:00Z http://memoria.ifrn.edu.br/handle/1044/398 New record of blue swimming crab Callinectes sapidu Rathbun, 1896 (Crustacea: Portunidae) for the state of Rio Grande do Norte, Northeastern Brazil Alencar, Carlos; Moraes, Sávio; Araújo, Paulo; Brito, Vanessa; Freire, Fúlvio The species Callinectes sapidus is reported for the first time in the state of Rio Grande do Norte, Northeastern Brazil. In Brazil, this species is only known from the state of Rio Grande do Sul to the state of Paraíba. In this work, one more gap about the distribution of this species was discovered. Samplings were gathered in two localities: Cavalos River and Ceará-mirim River, north and east coast of Rio Grande do Norte, respectively. This new record increases information about the singular distribution of this species, known for being the only species of Callinectes with disjoint distribution in the Americas. 2013-12-01T00:00:00Z http://memoria.ifrn.edu.br/handle/1044/393 Riqueza e importância das plantas medicinais do Rio Grande do Norte Paulino, Renan; Henriques, Gabrielly; Coelho, Maria; Araújo, Paulo Foram analisados estudos conduzidos em treze áreas do estado do Rio Grande do Norte a fim de obter o Índice de Importância Relativa (RI) e a riqueza de espécies nativas arbustivas e arbóreas de plantas de uso medicinal. As plantas medicinais distribuíram-se em 34 famílias, 65 gêneros e 85 espécies. As famílias que com maior número de indivíduos foram: Mimosaceae (8 spp.), Caesalpinaceae (7 spp.), Euphorbiaceae (6 spp.), Anacardiaceae (4 spp.). Os gêneros mais numerosos foram Mimosa e Caesalpinia (3spp.), e Cordia, Bauhinia, Capparis, Erythroxylum, Cnidoscolus, Croton, Piptadenia com 2 spp. Verificou-se que 29 espécies de plantas medicinais apresentaram alto valor de importância relativa (RI>1,0). O Estado do Rio Grande do Norte apresenta grande diversidade de espécies de uso medicinal, mas, são necessários mais estudos florísticos, fitossociológicos, etnobotânicos, dentre outros que visem dar suporte a conservação e uso sustentável da biodiversidade no Estado. 2011-01-01T00:00:00Z
