The Neogene of Kutch, India is well known for its rich marine and terrestrial vertebrate assemblages. However, the data piscean fauna from middle Miocene very scarce. We report here additional chondrichthyan osteichthyan remains deposit Chhasra Formation, Palasava site, Gujarat, India. elasmobranchs include Carcharhinus Blainville, 1816 (C. brevipinna (Müller & Henle, 1839), C. falciformis ...

Seamounts are globally important and essential ecosystems for supporting maintaining marine biodiversity. In the Mallorca Channel, three prominent seamounts present: Ausias March, Ses Olives Emile Baudot. Currently, this area is being evaluated inclusion in Natura 2000 network. For objective surveys were conducted of Channel during July 2018 2020. Samples macro-invertebrates obtained deep sea r...

Impacts of climate change on phytoplankton species are very focusing issues nowadays. This research explored the probable impacts different pH (pH 5.90 to 9.10) and salinity (0.60 3.0 ppt) concentrations freshwater Chlorella vulgaris, Euglena granulata Scenedesmus quadricauda. The initial community composition was 4:2:1 for three taxa, which changed 6:3:1, 6:2:1, 6:3.5:1 9:4:1 in 5.90, 9.10 2.2...

We analyzed the dietary copper effects in the estuarine crab Neohelice (Chasmagnathus) granulata and its interaction with water salinity. Crabs were maintained at 2 per thousand and 30 per thousand salinity for 5 weeks and they were fed with commercial food supplemented with the green alga Scenedesmus vacuolatus previously exposed to copper. No mortalities were observed, but crabs maintained at...

The monotypic Indo-Pacific genus Parastromateus Bleeker, 1864 is morphologically peculiar among carangid fishes in its overall body form and has been difficult to place phylogenetically. This has been partly the result of a lack of detailed morphological data for this and other carangid fishes. Here, we describe and analyze the osteology of Parastromateus niger (Bloch, 1795), review its taxonom...

A taxonomic review of the scorpaenid genus Pteroidichthys Bleeker, 1856 resulted in recognizing four valid species, including two new species; P. acutus n. sp., P. amboinensis Bleeker 1856, P. caussei n. sp., and P. noronhai (Fowler 1938). The genus Pteropelor Fowler, 1938 is regarded as a junior synonym of Pteroidichthys. Rhinopias godfreyi Whitley 1954, previously treated as a valid species, ...

The Pampean region is a crucial area to obtain sensitive paleoclimatic lacustrine archives due the presence of shallow environments in territory non impacted by humans until last centuries. In this study, we provide paleoecological reconstruction for ca. 700 years based on multiproxy record from Laguna Blanca Grande, Olavarría (Buenos Aires, Argentina). Our inferences, which were sedimentary pr...
