1. Settlement of the barnacle Balanus trigonus Darwin, 1854, on Panulirus gracilis Streets, 1871, in western Mexico
Abstract A large number of specimens (2765) of the acorn barnacle Balanus trigonus Darwin, 1854, were observed on the spiny lobster Panulirus gracilis Streets, 1871, in western Mexico, including recently settled cypris (1019 individuals or 37%) and encrusted specimens (1746) of different sizes: <1.99 mm, 88%; 1.99 to 2.82 mm, 8%; >2.82 mm, 4%). Cypris settle

2. Comments to Angulo et al. 2016 on “Sea-level fluctuations and coastal evolution in the state of Rio de Janeiro, southeastern - Brazil” by Castro et al. 2014
ABSTRACT Interpretation of sea-level indicators is essential when studying paleo sea-level fluctuations during the Holocene. Sea-level indicators may have different origins, such as geological (beachrocks) and biological (vermetids and barnacles). In order to reconstruct paleo sea-level, it is necessary to attribute an indicative meaning to each sea-level in

3. Efecto inhibidor del dióxido de germanio sobre el biofouling del puerto de Mar del Plata
ABSTRACT Marine biofouling on any new material immersed in seawater can lead to extra costs due to increased maintenance, or/and even mechanical wear, and/or biodeterioration that require costly antifouling measures. Fouling organisms growing on immersed manmade surfaces affect hulls, piers, buoys, aquaculture and pipes mainly. Following adsorption of a cond

4. Epibiosis in decapod crustaceans by stalked barnacle Octolasmis lowei (Cirripedia: Poecilasmatidae)
Stalked barnacles Octolasmis lowei Darwin, 1851 are frequently found attached to decapod crustaceans. Their epibiotic association depends on many factors, which are mainly related to characteristics of the host's biology. This study evaluated the infestation and distribution of stalked barnacles in the branchial chambers of crabs, and analyzed the data with

5. Comunidades de hidrozoários (Cnidaria) estuarinos do sudeste e sul do Brasil / Communities of stuarine hydrozoans (Cnidaria) from south and southeast of Brazil
The majority of the hydrozoans is marine, but they are also often recorded in estuaries. This environment is considered one of the most important in number of biological invasions. The Brazilian brackish hydrozoan fauna is practically unknown, except for some scattered records. The goals of this study are (1) to survey the planktonic and benthic hydrozoans f

6. Acumulação de elementos traço em organismos no estuário da Lagoa dos Patos / Acumulation of trace elements in organisms in the Patos Lagoon
Neste trabalho teores de elementos traço As, Cd, Cu, Cr, Fe, Mn, Pb, Ni e Zn foram determinados no camarão-rosa Farfantepenaeus paulensis, no cirripédio Balanus improvisus e no mexilhão Perna perna, coletados entre os anos de 2006 e 2010 no estuário da Lagoa dos Patos. Os resultados foram avaliados em função das variações hidrológicas interanuais o

7. Epibionts on Arenaeus cribrarius (Brachyura: Portunidae) from Brazil
Mean prevalence and intensity of infestations by epibionts were evaluated in Arenaeus cribrarius (Lamarck, 1818), based on monthly samplings (May/1991 to April/1993), in Ubatuba, Brazil. Bryozoans were quantified in terms of colony numbers and barnacles by the number of specimens. Prevalence of infestation was determined in 1,914 individuals of A. cribrarius

8. Zonación vertical del macrobentos de sustratos sólidos del estuario del río Massangana, Bahía de Suape, Pernambuco, Brasil
The estuarine area of the Massangana River (Pernambuco, Brazil) undergoes several kinds of interventions as a result of the activities of the Suape Industrial and Harbor Complex, which could affect local biotic communities. Thus, this study aimed to verify the composition of the benthic macrofauna of hard substrates regarding their vertical distribution in o

9. Ecologia trÃfica das anÃmonas-do-mar Anthopleura cascaia e Anthopleura krebsi (cnidaria: anthozoa) em duas praias de Pernambuco, Brasil
Studies of trophic ecology are fundamental to understanding the role that the species play in the ecosystem. Sea anemones are important components of reef environments, but few studies address the relationship anemone and its prey. So, it was developed a study on the species Anthopleura cascaia and Anthopleura krebsi on Piedade and Carneiros beach, in Pernam

10. PolidorÃdeos (Polychaeta: spionidae) em Crassostrea rhizophorae (Mollusca: bivalvia) de cinco rios da costa pernambucana
The Crassostrea rhizophorae occurs along the coast of Brazil serving as food to coastal communities and its production helps the local socio-economic development. Polydiariosis is one of several diseases in the world oyster culture. This disease is caused by a polychaete which drills the shell and inhabits a mud blister inside the oyster; thus, the oysterâs

11. Cirripedia Balanomorpha del estuario del Río Paripe (Isla de Itamaracá, Pernambuco, Brasil)
Barnacles are animals characteristic and abundant of intertidal region on marine and estuarine environments worldwide, but they are little known in the areas of tropical mangroves. This study was done with the aim to know the barnacles' species of the estuary of the Paripe River (Pernambuco, Brazil), indicating some characteristics of its distribution throug

12. Contaminação ambiental por compostos organoestânicos
The occurrence and the effects of organotin compounds (OTs) have been studied since a long time, due to their widespread use and deleterious effects. Some OTs are used as pesticides in crops, or as biocides in antifouling paints, applied in the ship hulls to avoid attachment and growth of tube worms, mussels and barnacles. However, "nontarget" organisms may
