The Magnitude of Global Marine Species Diversity
The first register of the marine species of the world is compiled and it is estimated that between one-third and two-thirds of marine species may be undescribed, and previous estimates of there being well over one million marine species appear highly unlikely. Expand
The correlates of foraging mode in a community of brazilian lizards
Mesure de l'intensite de l'approvisionnement chez des especes sympatriques, Ameiva ameiva, Cnemidophorus lemniscatus, Kentropyx striatus et Anolis auratus
Human-mediated global dispersion of Styela plicata (Tunicata, Ascidiacea).
The results of the present study indicate that commercial shipping could be the main cause for the global distribution of S. plicata, and the northwestern Pacific region is hypothesized as the center of distribution of the species. Expand
An experimental test of colonization ability in the potentially invasive Didemnum perlucidum (Tunicata, Ascidiacea)
While recruitment was somewhat greater (number of new colonies) on bare plates, this species can colonize already occupied substrates and, surprisingly, colony area was always similar between treatments, thus, D. perlucidum colonizes substrates very efficiently, especially when unoccupied space is available.

Keys for the identification of families and genera of Atlantic shallow water ascidians
Here we present tabular keys for families and genera of ascidian species found in shallow waters in the Atlantic Ocean. Characters used in the keys are illustrated or shown in photos of dissectedExpand
Introduced and native Phlebobranch and Stolidobranch solitary ascidians (Tunicata: Ascidiacea) around Salvador, Bahia, Brazil
The large number of cryptogenic and introduced species indicates the necessity of monitoring TSB for expansion of these populations and the need for the establishment of control programs. Expand
Rapid Assessment Survey of introduced ascidians in a region with many marinas in the southwest Atlantic Ocean , Brazil
In August 2014, we performed Rapid Assessment Surveys (RAS) in seven marinas along circa 70 km of the coastline of Ilha Grande Bay (IGB), southeastern Brazil to evaluate diversity in the AscidiaceaExpand
(2S,3R)-2-aminododecan-3-ol, a new antifungal agent from the ascidian Clavelina oblonga.
A new antifungal agent, (2S,3R)-2-aminodododecan-3-ol (1), has been isolated from the ascidian Clavelina oblonga collected in Brazil by analysis of spectroscopic data. Expand
Bivalve cultures provide habitat for exotic tunicates in southern Brazil.
The tunicate community associated with shellfish farms during the past 10 years is described and it is emphasized that the diversity of possibly introduced species also requires close monitoring for rapidly expanding populations, since a diversity of life cycles and biological requirements also increases the probability of the appearance of a new pest.

Antibiotic, cytotoxic and enzyme inhibitory activity of crude extracts from Brazilian marine invertebrates
Overall, the crude extracts of marine invertebrates herein investigated presented a high level of cytotoxic and antimycobacterial activities, a lower level of antibacterial activity and only a small number of crude extracts inhibited L-APRT. Expand
