Ichthyofauna of the Reserva Biológica Guaribas and surrounding areas, state of Paraíba, Brazil

Abstract

The removal and management of the Atlantic Forest over the past centuries caused the destruction of most of this ecosystem. Among the few remaining areas of Atlantic Forest north of the São Francisco River is the Reserva Biológica (REBIO) Guaribas. This study inventoried the ichthyofauna of the REBIO Guaribas (Mamanguape, Paraíba) and its surroundings. Two streams were sampled bimonthly (1 within the REBIO and the other adjacent to it) and another 11 additional sites were sampled once, resulting in 18 species of fish (7 families and 7 orders). Characiformes was the most representative order, with12 species. This species list is an important tool for impact assessments as well as conservation and management plans, given the current state of knowledge about Brazilian rivers and streams, especially those of the northeastern Atlantic Forest.

Continental ichthyofauna from the Paraíba do Norte River basin pre-transposition of the São Francisco River, Northeastern Brazil

“…However, the current results also recognize this species to occur in Paraíba do Norte River basin. Occurrences of this species in other basins within the MNCE ecoregion in Texeira et al 2017and Gouveia et al (2017) The source of the Paraíba do Norte River is located at Serra de Jabitacá, a region known to also separate water to the Pajeú River sub-basin which is an affluent from the São Francisco River. Paraíba do Norte River basin shares 20 native species with São Francisco River basin out of 38 native species recognized in the present study.…”

“…Porém, recentemente foi publicado um estudo de Gouveia et al 2017, em uma reserva ambiental no município de Mamanguape (Reserva do Rio Guaribas), também no estado da Paraíba, os autores elencaram 18 espécies, número aproximado ao encontrado no presente trabalho, o qual corrobora também, com a captura das duas espécies introduzidas coletadas neste estudo (O. niloticus e P. reticulata), ambas dentro das áreas de proteção no estado da Paraíba.…”

“…Essas regiões de nascentes são consideradas Áreas de Preservação Permanente (APPs), portanto, seria muito importante para conservação desse manancial, que o limite deste Parque Estadual abrangesse toda a região de nascentes. A partir desse e outros estudos (Gouveia et al 2017), que vem sendo desenvolvidos podemos constatar a vulnerabilidade desses ecossistemas ao estabelecimento de espécies invasoras e possíveis impactos futuros que estas possam vir a causar para a fauna endêmica da região. Dessa forma, faz-se de grande importância a implementação de Planos de conservação e manejo para essas áreas de preservação que encontram-se dentro do bioma Mata Atlântica.…”

Continental fishes from the Tambaba Environmentally Protected Area, Paraíba State, Brazil

“…The Atlantic Florest originally extended from the Rio Grande do Norte State (Northeastern region of Brazil) to the Rio Grande do Sul (Southern region) in Brazil. Throughout its distribution exhibits several types and subtypes of tropical and subtropical forests, comprising the second largest forest in South America (Gouveia et al, 2017). Preservation and conservation of the Atlantic Forest rivers and ichthyofauna are imperative due to its high endemicity rate (e.g., Gomiero & Braga, 2006;Oyakawa et al, 2006;Menezes et al, 2007;Miranda, 2012;Gouveia et al, 2017) and exclusive ecological characteristics (e.g., Barbosa & Costa, 2012;Pereira et al, 2012).…”

Menezes et al (2007) listed 325 freshwater fish species for a portion of Atlantic forest in the Brazilian southeastern region.…”
