Rottboellia Cochinchinensis

Rottboellia cochinchinensis is an aggressive invasive species native to Asia. This species is known worldwide for invading crops and disturbed habitats in tropical and subtropical regions. In Brazil, R. cochinchinensis had its southernmost record in São Paulo state; however, in this study we expand its distribution to Santa Catarina state, in the South Region of Brazil, based on the discovery of a population in Blumenau municipality. These new records are ca. 440 km distant from the nearest known population, in São Paulo municipality, São Paulo state, Brazil.

AbstractRecently, the end-Devonian mass extinction (Hangenberg Crisis, 359 Ma) was identified as a first-order mass extinction, albeit not one of the “Big Five” events. Many marine and terrestrial organisms were affected by this crisis. The cause of this mass extinction is still conjectural and widely discussed. Here we report anomalously high mercury (Hg) concentrations from the South Tian Shan (Uzbekistan), together with correlation using conodont biostratigraphic data. Hg enrichment (to 5825 ppb) was detected in marine deposits encompassing the Hangenberg Crisis. In the Novchomok section, the Hangenberg Crisis interval does not contain typical Hangenberg Black Shales; however, by means of inorganic geochemistry (enrichment of redox-sensitive elements such as Mo, V, and U) we detected an equivalent level despite the lack of marked facies changes. This is the first record of Hg and Hg/total organic carbon anomalies in marly shales, marls and carbonates that are totally independent of facies changes, implying that volcanism was the most probable cause of the Hangenberg Crisis. This conclusion is confirmed by the presence of a negative δ13C excursion, which may reflect massive release of isotopically light carbon from volcanogenic and thermogenic devolatilization likely combined with increased arc-volcanism activity worldwide at the end of the Devonian.

Abstract Remains of teiids assignable to the Tupinambinae (Tupinambis sp. or Crocodilurus sp.) are here described from the middle Miocene Collón Curá Formation at Cañadón del Tordillo, in Neuquén province, Argentina. No tupinambine species presently inhabits the region of the fossil locality. The fossils represent the westernmost distribution of fossil tupinambine teiids in Patagonia, enlarging the known geographical distribution of the teiids through the Miocene in a longitudinal range. Also, they constitute the first record of lizards from the Colloncuran SALMA, partially filling the record of tupinambine teiids for the South American Miocene.

This paper reports seven species of opisthobranchs from the intertidal zone of the south Saurashtra coastline off the Arabian Sea, Kathiawar Peninsula, west coast of India. Field surveys were undertaken along the intertidal zones of south Saurashtra coast during 2012–2014. In this study, seven species belonging to six families were recorded, of whichHaminoea ovalis, Flabellina bicolor, Phidiana militaris, Baeolidia palythoaeandSakuraeolis gujaraticaare new records from this coastline.

Lernaea Cyprinacea

Lernaea cyprinacea is an ectoparasitic copepod that can result in the mortality of the host by causing hemorrhages, ulcerations, and secondary infections. Lernaea cyprinacea is widely distributed in Argentina. Previous reports are restricted almost exclusively to cases of parasitism in fishes; copepod parasitism of anuran larvae is rarely documented. This is the first record and description of the parasitic infestation of L. cyprinacaea on tadpoles of the exotic and invasive species Lithobates catesbeianus in Argentina. A total of 15 tadpoles and 21 newly-metamorphosed individuals of L. catesbeianus were collected from the mountain town of Río de los Sauces, and 12 tadpoles from the Toledo Stream. A maximum of two parasites per host was found, principally in the cloaca. Clinical symptoms of inflammation hemorrhage and ulcers in the skin with mucus formation in the attachment area of parasites were observed.

Dinoflagellates of the genus Ceratium are generally marine organisms, but rare occurrences in freshwater have been observed in Brazil. In this paper we are recording for the first time the presence of Ceratium furcoides, an invasive species, in a shallow, natural intermittent pool formed at a high-altitude at the southern end of the Iron Quadrangle, an iron-mining district of Minas Gerais State (Southeast Brazil). Samples were collected in October and November of 2010 (rainy period). The population density of this organism observed in Lagoa Seca (“Dry Pool”) was very low, at most 4 ind L–1. Mountain lakes are extremely vulnerable to atmospheric deposition of organisms, making them valuable witnesses both of the many forms of impact arising from human activities and of the extended global connections that facilitate the dispersion and introduction of new species over great distances. Studies on the population dynamics of C. furcoides in natural tropical systems are still rare and very recent to the brazilian scenario and hence the monitoring of its dynamics and the potential impact on aquatic communities of its becoming established are essential to an understanding of the process of bioinvasion by this species.

This study provides the first record of the exotic invasive bivalve Isognomon bicolor for the State of Paraíba, Northeastern Brazil. It has been found to occur in at least twelve coastal reefs along the coast. We also present its first record for the State of Alagoas and new record localities for the States of Rio Grande do Norte and Pernambuco, including its occurrence in hypersaline estuaries. From these records the distribution range of I. bicolor has been expanded to the littoral region of Northeast Brazil, where this invasive species seems well established.
