Metazoan parasites of Hoplias aff. malabaricus, Trachelyopterus galeatus and Schizodon borellii (Osteichthyes) from the Protected Area and its main tributary, Brazil.

A study of the parasite-host interactions was conducted in the protected area popularly known as the "Refúgio Biológico de Santa Helena" and its tributary, the São Francisco Falso River. For each of the three host species, Schizodon borellii, Hoplias aff. malabaricus, and Trachelyopterus galeatus, 30 fish were collected from 2018 to 2019. A total of 2172 parasites were identified among the three host species. Among these, the Monogenea class had the highest number of species, with 26 taxa, followed by Copepoda with eight taxa, Digenea with six taxa, and Cestoda and Nematoda with one taxon each. Eleven new records of infection/infestation were found among the host species such as Urocleidoides paradoxus, Urocleidoides ramentacuminatus, Rhinoxenus arietinus, Mymarothecioides sp. (Monogenea), Ergasilus cf. bryconis, Lernaea devastatrix, and Brasergasilus sp. (Copepoda) parasitizing S. borellii. Trinigyrus sp., Vancleaveus sp. (Monogenea), Gamispinus diabolicus (Copepoda) present in T. galeatus, and Gamidactylus jaraquensis (Copepoda) present in H. aff. malabaricus. This study contributes to the record of parasite species occurrence in the vicinity of a protected area and helps fill gaps in the knowledge of fish parasitic fauna in the Neotropical region.

Foi realizado um estudo das interações parasitas-hospedeiros na área de proteção popularmente conhecida como "Refúgio Biológico de Santa Helena" e seu afluente, o Rio São Francisco Falso. Para cada uma das três espécies hospedeiras, Schizodon borellii, Hoplias aff. malabaricus e Trachelyopterus galeatus, foram coletados 30 peixes entre 2018 e 2019. Foi identificado um total de 2.172 parasitos entre as três espécies hospedeiras. Dentre estes, a classe Monogenea apresentou o maior número de espécies, com 26 táxons, seguida por Copepoda com oito táxons, Digenea com seis táxons, e Cestoda e Nematoda com um táxon cada. Foram encontrados onze novos registros de infecção/infestação entre as espécies hospedeiras tais como Urocleidoides paradoxus, Urocleidoides ramentacuminatus, Rhinoxenus arietinus, Mymarothecioides sp. (Monogenea), Ergasilus cf. bryconis, Lernaea devastatrix e Brasergasilus sp. (Copepoda) parasitando S. borellii. Trinigyrus sp., Vancleaveus sp. (Monogenea), Gamispinus diabolicus (Copepoda) presentes em T. galeatus, e Gamidactylus jaraquensis (Copepoda) em H. aff. malabaricus. Este estudo contribui para o registro da ocorrência de espécies de parasitos nas proximidades de uma área protegida, e ajuda a preencher lacunas no conhecimento da fauna parasitária de peixes na região Neotropical.(AU)

An ornithological inventory in a reforested woodlot in western Paraná state, southern Brazil

This paper presents an ornithological inventory taken between March and December of 2017 in the Brazilian state of Paraná. Although the surroundings contain one relatively well-known location in regard to ornithology, Iguaçu National Park, several other areas merit exploration, among them the Santa Helena Relevant Ecological Interest Area (ARIE-SH). The 1,479 ha ARIE-SH is essentially a large remnant of the Atlantic Forest located adjacent to the city of Santa Helena, Paraná, which commencing in the 1980s has undergone considerable reforestation with both native and exotic species, including fruit species. Prior to censusing bird species and to better characterize the avian community, we conducted a bibliographic review of earlier ornithological studies carried out at ARIE-SH. In addition, we conducted opportunistic and unsystematic observations in nearby locations. We recorded 311 species of birds. During the current inventory, and others conducted in the area since 2016, we recorded six Atlantic Forest endemic species, five species threatened in Paraná, and two globally threatened species. Common species which showed high Index of Frequency in Lists include (in descending order) Basileuterus culicivorus, Leptotila verreauxi, Cnemotriccus fuscatus, Corythopis delalandi, Turdus leucomelas and Arremon flavirostris. Nine species observed while conducting this census (Laterallus exilis, Amazona vinacea, Herpsilochmus longirostris, Campylorhamphus trochilirostris, Casiornis rufus, Campylorhynchus turdinus, Myiothlypis flaveola, Eucometis penicillata and Sporophila palustris) are the first records for this region.(AU)
