Abstract	In the last decade, several methods were applied to monitor the impact of oil pollution on marine organisms. Recent studies showed an eminent need to standardize these methods to produce comparable results. Here we present the first thorough systematic review of the literature on oil pollution monitoring methods in the last decade. The literature search resulted on 390 selected original articles, categorized according to the analytical method employed. Except for Ecosystem-level analyses, most methods are used on short-term studies. The combination of Biomarker and Bioaccumulation analysis is the most frequently adopted strategy for oil pollution biomonitoring, followed by Omic analyses. This systematic review describes the principles of the most frequently used monitoring tools, presents their advantages, limitations, and main findings and, as such, could be used as a guideline for future researches on the field.

Abstract	Multicentric Castleman disease (MCD) is a poorly understood, heterogeneous lymphoproliferative disorder with benign hyperplastic lymph nodes and systemic inflammatory symptoms. Human herpesvirus-8 (HHV-8) may be associated with MCD, whether or not the patient is infected with the human immunodeficiency virus (HIV). A 74-year-old man presented with anaemia, thrombocytopenia and bilateral axillary adenomegaly of unknown origin. The patient was admitted to the hospital two years ago with clinical signs of weight loss, asthenia, anorexia and a maculopapular rash on the trunk and back. Blood analysis showed pancytopenia (haemoglobin 7.7 g/dL, leucocytes 2.55 x 10

Abstract	Caulerpin is a bisindolic alkaloid that has been obtained from many species of the genus Caulerpa. The main objective of this paper is to evaluate four extraction methods of caulerpin in the C. racemosa: maceration (DMA), Soxhlet extraction (SOX), ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE). The methods were compared through caulerpin content quantified by Ultraviolet-visible (UV-vis) spectrophotometry. The highest extract yield was obtained by SOX but the highest contain of caulerpin was presented in the MAE extract. The caulerpin content was significant different within the extacts by MAE and UAE, it yielded by MAE more than three times as much as UAE. The most efficient caulerpin extraction method had the parameters solvent, temperature and time optimised. Thus, the best conditions were achieved with MAE in ethanol during 7 min at 90 °C. Therefore, this work suggests an improved routine analysis of caulerpin by the green chemistry concept.

Abstract	The study aims to understand the dispersal patterns of non-indigenous Tubastraea spp. (Sun Coral) larvae in the Brazil Current (BC), specifically in the Cape Frio recurrent cyclonic eddy (CFE) scenario. For this, the Regional Ocean Model System was used to simulate the hydrodynamic fields in a high-resolution nested grid, where a model of lagrangian floats, in a good approximation of the larvae properties and considering massive planulation events, was coupled with surface larval release from the Campos Basin area. The simulation was representative of mesoscale features compared to similar studies, ARGO vertical profiles and a py-eddy-track algorithm was used to obtain eddy variables, such as radius, rotational and translational velocities. These parameters are fundamental to access when an eddy tends to trap or not the water, heat and plankton in its interior. CFE turned out to be highly nonlinear, with a strong tendency to trap larvae in its core, acting as a dispersal constrictor when compared with the organisms in the axis of the higher speed of BC. A strong negative correlation (-0.75) was found between the days that larvae were inside the eddy and their distance from the origin. None of the 48,000 larvae released during simulated experiment a 16-day spawning event reached the coast. There are two different patterns for the dispersal, one along the shelf break and another, with higher larval density, off from the 1000 m isobath. The CFE's presence allows larvae to remain in the same region for longer periods, although in offshore areas. Therefore, as there is considerable availability of fixed substrates on oil rig structures, larvae could settle on them resulting in a possible inter-platforms connectivity between populations of Tubastraea spp. Also, regions in the CFE that present downward vertical velocities (downwelling), may move young larvae to depths of about 60 m suggesting that subsurface colonizations are possible due to specific dynamics of propagating cyclonic eddies. So, identifying the main factors that affect the dispersion of propagules is essential to subsidize management policies for controlling bioinvasion associated with exploitation of hydrocarbon resources in offshore areas.

Abstract	Marine biofouling is a natural process by which many organisms colonize and grow in submerged structures, causing serious economic consequences for the maritime industry. Geniculate calcareous algae (GCA; Corallinales, Rhodophyta) produce bioactive secondary metabolites and are a promise for new antifouling compounds. Here, we investigated the antifouling activity of four GCA species-

Abstract	The health of the coral species Siderastrea stellata was investigated as an indicator of climate changes impacts at the Fernando de Noronha Marine National Park, southwestern Atlantic Ocean. Chlorophyll a maximum quantum yield and Rapid Light Curves (RLCs) were produced using a red-light pulse amplitude modulated fluorometer, Mini-PAM in S. stellata colonies. We collected genetic material from the same colonies in order to identify Symbiodineaceae hosted in each of them, considering that the colonies showed very different pigmentations between them. Our findings showed that colonies with pink pigmentation may be associated with higher temperatures, while indicating a high saturation point (Ek) and consequent greater efficiency in the dissipation of radiant energy. Our genetic analysis also demonstrated a high fidelity in association with Cladocopium spp. predominantly. Despite this, we hypothesized that this association may be the result of changes in populations of Breviolum spp. due to stressful events.
