Advances in biologging technology have enabled 3D dead-reckoning reconstruction of marine animal movements at spatiotemporal scales of meters and seconds. Examining high-resolution 3D movements of sharks (Galeocerdo cuvier, N = 4; Rhincodon typus, N = 1), sea turtles (Chelonia mydas, N = 3), penguins (Aptenodytes patagonicus, N = 6), and marine mammals (Arctocephalus gazella, N = 4; Ziphius cavirostris, N = 1), we report the discovery of circling events where animals consecutively circled more than twice at relatively constant angular speeds. Similar circling behaviors were observed across a wide variety of marine megafauna, suggesting these behaviors might serve several similar purposes across taxa including foraging, social interactions, and navigation.

Le référentiel taxinomique du Système d'information halieutique (SIH) de l 'Ifremer
Provedor de dados: 5
Autores: Woehrling, D.
The adoption of a single reference data base for IFREMER cannot be missed within the framework of continuous monitoring of biological data. This entails standardization of taxa names connected with an up-to-date taxonomic nomenclature, consistent with international valid lists. The necessity of relative stability of IFREMER's taxonomic data base simultaneously opened on nomenclature's evolution imposes the major constraints for structural choices. The SIH taxonomic reference database is the first step toward the future complete reference data base for IFREMER.

Allis shad (Alosa alosa) exhibit an intensity-graded behavioral response when exposed to ultrasound
Provedor de dados: 5
Autores: Wilson, M; Acolas, M; Begout, Marie-laure; Madsen, P; Wahlberg, M.
Most fish cannot hear frequencies above 3 kHz, but a few species belonging to the subfamily Alosinae (family Clupeidae) can detect intense ultrasound. The response of adult specimens of the European allis shad (Alosa alosa) to sinusoidal ultrasonic pulses at 70 and 120 kHz is tested. The fish showed an intensity-graded response to the ultrasonic pulses with a response threshold between 161 and 167 dB re 1 mu Pa (pp) for both frequencies. These response thresholds are similar to thresholds derived from juvenile American shad (Alosa sapidissima) in previous studies, supporting the suggestion that these members of Alosinae have evolved a dedicated ultrasound detector adapted to detect and respond to approaching echolocating toothed whales.

A hidden early source of information on north-eastern Brazilian zoology
Provedor de dados: 16
Autores: Boeseman, M.
Attention is drawn to some hitherto overlooked paragraphs on the north-eastern Brazilian fauna hid- den in a historiographic account of Count Johan Maurits' govenorship (1637-1644), published by Caspar van Baerle (Barlaeus) in 1647, a year before the publication of Marcgrave &amp; Piso's famous Historia naturalis Brasiliae and based on the same sources.

Fauna Europaea: Hymenoptera: Symphyta &amp; Ichneumonoidea
Provedor de dados: 16
Autores: Achterberg, K. van; Taeger, A.; Blank, S.M.; Zwakhals, K.; Viitasaari, M.; Sick Ki Yu, D.; Jong, Y. de.
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all extant European terrestrial and freshwater animals, their geographical distribution at the level of countries and major islands (west of the Urals and excluding the Caucasus region), and some additional information. The Fauna Europaea project comprises about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. Fauna Europaea represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and...

The correlations between certain features of the journal Neotropical Ichthyology and its impact factor: a comparative analysis at the thematic and national levels
Provedor de dados: 83
Autores: Menezes,Sabrina; Strehl,Letícia.
The present article analyzes the relationship between characteristics of the journal Neotropical Ichthyology and its impact factor (IF) between 2006 and 2011 using bibliometric descriptive quantitative methods. To perform this analysis, two samples of journals included in Journal Citation Reports (JCR) were studied. One sample was composed of journals classified within the subject of zoology, and the other contained journals from different areas published in Brazil. The instrument used for data collection was a database created in Microsoft Excel 2007 and the Statistical Package for the Social Sciences (SPSS) version 18. The results show that despite its short history, Neotropical Ichthyologyhas exhibited a distinctive impact, as manifested in a...

Freshwater gastropods in the Northern littoral mesoregion of Espírito Santo, Brazil
Provedor de dados: 3
Autores: Souza, Marco Antônio Andrade de.
 Studies on the distribution of molluscs in Brazilhave been conducted since the beginning of the twentieth and the knowledge of the species distributed in the country represent important findings, which contribute to the understanding of human diseases and those of veterinary importance, transmitted by them. In order to verify the distribution of freshwater gastropods in Espírito Santo, a malacological surveywas carried out in nine municipalities that comprise the Northern mesoregion of the State, between January 2010 and February 2015. Initially the water collections occurring in the municipality were verified and the lotic systems at different levels of use and conservation were determined. Molluscs were collected monthly using a hand net adapted to a...
