Cytogenetic analysis of three sea catfish species (Teleostei, Siluriformes, Ariidae) with the first report of Ag-NOR in this fish family

Triploidy is common in human pregnancies. It is detected in 1 to 2% of clinically recognized pregnancies and in approximately 15 to 20% of spontaneous abortions produced by chromosome anomalies. We report a premature liveborn girl (30 weeks of gestation) with microcephaly, facial dysmorphism and skeletal abnormalities who died at one day of age due to respiratory failure. The placenta showed partial hydatiform mole. Autopsy revealed no internal malformations. Cytogenetic analysis of 100 metaphases obtained from renal tissue culture revealed a 68,XX[73]/69,XXX[27] karyotype. To our knowledge this is the first report in the literature of 68,XX[73]/69,XXX[27] mosaicism in a liveborn infant.

Gulf Of Tehuantepec

Abstract This is the first report of coexistence of pedunculate barnacles, Conchoderma auritum and C. virgatum in the mouth, and with the copepod Gloiopotes huttoni in the precaudal zone, on the black marlin, Istiompax indica, a as host. This is also the first note of a new non-mammalian host for C. auritum. The host specimen was caught in sport fishing in the Gulf of Tehuantepec, eastern Pacific. A review of registered occurrences of the genus Conchoderma in species of the fish family Istiophoridae is provided.

Ideal Group

The present study was conceptualized to study the muraenid species (moray eels) occurring around the volcanic archipelagos of the Azores, Madeira, Selvagens, Canary and Cabo Verde islands (eastern-central Atlantic). The biogeographic patterns of these species were analysed and compared. We then hypothesized that this fish family is an ideal group for testing at small-scale the coherency of Macaronesia and its direct biogeographic units: i.e. the Azores, Webbnesia and Cabo Verde, as proposed in recent scientific literature. Additionally, this paper provides for the first time separate fishery statistics for this group in the region that were analysed to contrast the biogeographic results.

A sporulating Aspergillus is described from a piece of Eocene amber originating from the Dominican Republic. The Aspergillus most closely resembles a form of the white spored phase of Aspergillus janus Raper and Thom. This is the first report of a fossil species of Aspergillus.
