“…In the sampling area, ballast water and bivalve transplants are probably the main routes of entry of invasive species. Organisms included in this ballast water and originating from a distant port of origin are represented by bacteria, protozoa, and invertebrates, mainly as resting stages able to survive travel conditions [65] and establish a new reproductive population in the new ecosystem. Additionally, bivalve transplants activities are also frequent, since the three sampling areas are important cockle and clam shellfish beds in Galicia.…”

This paper compiles the data regarding the first occurrence of Oithona davisae and O. atlantica in NW Spain, which is supported by morphological and molecular analysis. Additionally, we investigated the seasonal dynamics of the invasive O. davisae, revealing that its abundance is conditioned by upwelling-downwelling patterns in the Rías Baixas of Galicia. Temperature was the most correlated factor, with higher abundances in upwelling relaxation-downwelling events. More studies in long-term zooplankton dynamics and molecular analysis are needed to determine if O. davisae is displacing other native species of the same genus, such as O. atlantica, in Galician waters.

“…Damages resulting from the toxic algal blooms cannot be considered resolved by reducing their populations. Indeed, numerous toxic Dinophyceae produce cysts at their blooming, successively accumulating in the sediments where they wait for the return of favorable conditions to germinate [79]. The encystment phenomenon is regular and frequent in the Gulf of Gabès but affects a low variety of species.…”

The Gulf of Gabès, located in southern Tunisia, is a distinct and ecologically significant area in the Mediterranean Sea. Unfortunately, this dynamic marine ecosystem is experiencing cultural eutrophication, a process where water enrichment with nutrients like phosphorus and nitrogen salts leads to excessive algae growth, disrupting the ecological equilibrium and degrading water quality. In the Gulf of Gabès, key sources of nutrient pollution include industrial discharges, urbanization and agriculture. Eutrophication’s effects here include harmful algal blooms, oxygen depletion, and declining water quality, upsetting the marine ecosystem’s balance and impacting both fish and aquatic life. Nutrient enrichment interacts with trace metal pollution, overfishing and climate change. Future research must acknowledge and consider the complex interactions among these variables. Efforts in the Gulf of Gabès to address eutrophication involve tighter industrial regulations, enhanced agriculture and improved wastewater management, all crucial for preserving the marine environment’s integrity and ensuring sustainability for the future.

“…The ecological role of resting stages is still underestimated in marine biology textbooks, up to the point that terms like "cyst," "resting," or "diapause" are absent from the list of arguments at the end of each volume (see, e.g., Valiela, 1995;Barnes & Hughes, 1999;Levington, 2001;Kaiser et al, 2005). Nevertheless, resting stages are considered responsible for many of the intermittent occurrences of species and for their abundance/ rarity cycles in the marine coastal environment (Giangrande;Geraci & Belmonte, 1994;Boero et al, 1996;Belmonte et al, 2013;Rubino & Belmonte, 2019a, 2019b. The injection of active stages from bottom sediments was put at centre of the "resurrection ecology" (Kerfoot & Weider, 2004) and, in contrast to supply side ecology (Gaines & Roughgarden, 1985;Lewin, 1986) where recruits arrive from adjacent areas, it pivots on species which subtract themselves from a planktonic role, resting as cysts in the same area of the active forms.…”

Resting stages are the strategy for species to avoid the variability of environmental conditions. In coastal confined marine habitats, variability of conditions is higher than in the open sea, and bottoms accumulate plankton resting stages in the so-called “marine cyst banks”. The benthic-pelagic coupling generated by this bi-location of plankton, however, is not clearly evident for all the involved species. This result is due to the still scant knowledge of the life cycles and life histories of single species. The study of plankton dynamics from the benthos point of view is useful and informative and it increases the potential complexity of a planktonic community in a confined area. Keywords: plankton, life cycles, resting stages, cysts, benthic-pelagic coupling, resurrection ecology.
