The hydrozoan Macrorhynchia philippina is considered a circumtropical and subtropical species. In the last years, its distribution has been spread at higher latitudes because of global warming, facilitated by its invasive character. Macrorhynchia philippina develops prominent colonies that have the potential to colonize rapidly new substrates, showing invasive potential. See details Riera, R., F. Espino & L. Moro. 2016. Progressing the invasion of the hydrozoan Macrorhynchia philippina (Kirchenpauer, 1872) in Atlantic archipelagos. Vieraea, 44: 117-120.

The common octopus (Octopus vulgaris, Cuvier 1797) is a promising species for aquaculture diversification, but the massive mortality during the first life stage is the main bottleneck for its commercial production. A total of 26 independent assays were used, including data from the bibliography and from experiments carried out by our group. Three comparisons were established: (i) crustacean zoeae vs Artemia, (ii) different crustacean zoeae species and (iii) Artemia enriched with marine lecithin (rich in polar lipids-PL and docosahexaenoic acid-DHA) vs previously used Artemia enrichments. The meta-analysis approach allowed a quantitatively review of independent studies with reliable conclusions, avoiding the subjectivity inherent to classical reviews. Check out!!. Garrido, D., V.M.

Intertidal mollusks are subjected to an intense environmental pressure, from human-induced stressors, mainly harvesting, to competition for food and space with other species. A long-term comparison (1994-2014) of limpet size has been conducted as a surrogate of the state of conservation of these two limpets. Both species showed populations dominated largely by small-sized individuals (<30 mm) and a lack of large adults (>60 mm). The proximity to coastal settlements was not a factor to explain limpet assemblage structure. The temporal (1994e2014) comparative study showed a sharp decrease in the mean size of both limpet species (7 mm in P. aspera and 5 mm in P. candei crenata). Riera, R., O. Pérez, O. Álvarez, D.
