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.

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.

Introduced ascidians in Paranaguá Bay, Paraná, southern Brazil
S sampling ascidian species near the port of Paranagua for a taxonomic study of this fauna to attempt to detect introduced species suggests that three species are native, one is a inter-regional introduction, two are introduced from the Pacific and the remaining 12 are cryptogenic. Expand
The biotic resistance role of fish predation in fouling communities
Examination of how predation can regulate fouling communities on artificial substrates in the coast of Brazil finds biotic resistance driven by predation was not ubiquitous but apparently targets one group of major economic and environmental impact. Expand
Rapid assessment survey for exotic benthic species in the São Sebastião Channel, Brazil
The marine fauna of the area of the port of Sao Sebastiao was described to detect introduced species and the large number of cryptogenic species illustrates the need for a long-term monitoring program, especially in areas most susceptible to bioinvasion. Expand
Marine and coastal environmental education in the context of global climate changes - synthesis and subsidies for ReBentos (Coastal Benthic Habitats Monitoring Network)
A importância da educacao ambiental marinha (EAM) vem tomando relevância a medida que aumenta a expectativa de impactos nos ecossistemas brasileiros ocasionados por mudancas nos ambientes costeiros.… Expand
Lack of COI variation for Clavelina oblonga (Tunicata, Ascidiacea) in Brazil: Evidence for its human-mediated transportation?
The evidence, including the absence of C. oblonga in the country’s northern tropical waters, its association with artificial habitats and lack of COI variation suggest that the species has been introduced in the southeastern and southern Brazilian coasts. Expand
Fifty years of ascidian biodiversity research in São Sebastião, Brazil

This study provides one of the most detailed datasets of ascidian diversity from the south-western Atlantic Ocean and believes that the temporal data compiled here will serve as a baseline for monitoring and management of ascidians in SS. Expand
Biotic interference in parasite transmission: Can the feeding of anemones counteract an increased risk of parasitism in amphipods at higher temperature?
The results show that the effect of non-host species on trematode transmission might not be strong enough to mitigate increased parasite transmission at higher temperatures, and all findings point towards a higher risk of parasite-induced mortality of small crustaceans with increasing temperature, which is of particular concern in the context of global warming.

The role of Didemnum perlucidum F. Monniot, 1983 (Tunicata, Ascidiacea) in a marine fouling community.
Results suggest that D. perlucidum may be a weak competitor in a marine fouling community comprised mainly of non-indigenous species, and continuous monitoring is desirable to better understand its fouling dynamics. Expand
