A B S T R A C TThis study analyzed a comparison of the Atlantorchestoidea brasiliensis (Crustacea: Amphipoda) density of a preserved area with that of an urbanized one, both on Peró Beach, Cabo Frio, Rio de Janeiro state. Seasonal samplings were conducted of the population of talitrideos and an estimation of the number of swimmers in these areas was made. The lowest frequency of swimmers was recorded in the preserved area regardless of sampling period. In the urbanized area swimmers were most frequent in January (550 individuals/m -1 ). The statistical tests showed the absence of Atlantorchestoidea brasiliensis in the urban area, indicating that this species is extremely sensitive to the urbanization of beaches. The use of the Talitridae family as an indicator of the impact of urbanization on the ecosystems of sandy beaches is also discussed.
R E S U M OEste trabalho é um estudo comparativo da densidade de Atlantorchestoidea brasiliensis (Crustacea: Amphipoda) no trecho urbanizado e no trecho preservado da praia do Peró, Cabo Frio, Rio de Janeiro. Foram realizadas coletas sazonais da população de talitrídeos, assim como uma estimativa do número de banhistas nessas áreas. Na área preservada foi registrada a menor freqüência de banhista independente dos períodos amostrados, enquanto que no trecho urbanizado a maior freqüência ocorreu no mês de Janeiro (550 indivíduos/m -1 ). As análises estatísticas mostraram a ausência de Atlantorchestoidea brasiliensis na área urbanizada em todos os períodos amostrados, indicando que essa espécie é bastante sensível à urbanização das praias. É discutida também a utilização da família Talitridae como indicadora de impactos oriundos dos efeitos de urbanização nos ecossistemas de praias arenosas.
We report the gross and microscopic findings and molecular identification of 2 cases of hyphate fungal infection in cetaceans from Brazil. The first case involved an adult male Atlantic spotted dolphin Stenella frontalis with localized pulmonary disease characterized by pyogranulomatous and necrotizing bronchopneumonia with intralesional hyphae. The second case involved an adult male Bryde's whale Balaenoptera edeni with orchitis, periorchitis, mesenteric lymphadenitis and pyogranulomatous bronchopneumonia with intralesional hyphae. PCR analysis from the dolphin's lung yielded Aspergillus fumigatus, and the fungus from the whale's mesenteric lymph node showed the greatest identity to Nanniziopsis obscura and Stagonosporopsis cucurbitacearum These cases represent the first reports of pulmonary aspergillosis by A. fumigatus in an Atlantic spotted dolphin and systemic mycosis by a possibly novel Onygenales in marine mammals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
