Species range shifts, biological invasions and ocean warming

Marine species are moving beyond their native geographical ranges in response to climate change and shifts other abiotic conditions, establishing populations at higher latitudes. At the same time, introduced into new marine regions as a consequence of an increasingly connected world. The success such range expansions, whether from associated with or human-mediated introductions, depends on biotic interactions environmental conditions recipient site and/or capacity adapt these conditions. Originating special session held Association for Sciences Limnology Oceanography (ASLO) Aquatic Meeting 2021, present Theme Section (TS) brings together current research 2 interrelated ecological topics: (1) invasive warming ocean, (2) climate-mediated shifts. Our investigation temporal trends publications highlights that only one-tenth studies examine species’ interaction ocean warming. topic shifting receives slightly more attention than driven invasions, but both exhibited comparable, similarly fast-growing publication rate. Overall, papers this TS provide evidence global warming, occasionally degradation, crucial factors altering distribution range-shifting species. Even though published literature even contributions infrequently focus between topics, we propose future collaboration scientists fields would advance our understanding impact distributions allow development conservation management plans ocean.

The Heatwave of Summer 2022 in the North-Western Mediterranean Sea: Some Species Were Winners

The warming trend of the Mediterranean Sea is a long-term process. It has resulted in northwards and westwards range expansion abundance increase thermophilic species, both native non-indigenous, shrinking cold-affinity species. Marine heatwaves (MHWs) are relatively short-term extreme episodes that responsible for spectacular mortality events some species have been extensively reported literature. In contrast, benefit from MHWs (the ‘winners’) much less studied. A record-breaking MHW occurred 2022 north-western Sea. We focus on three ‘winner’ green macroalgae Penicillus capitatus Microdictyon umbilicatum endemic seagrass Posidonia oceanica. capitatus, which mainly present area as an inconspicuous turf entangled filaments (espera stage), produced erect paintbrush-like stage where sexual reproduction takes place. umbilicatum, usually uncommon, bloomed to point clogging fishing nets. Finally, mass flowering P. oceanica late August–September, followed following year (April–May 2023) by extensive production dissemination fruits seeds. Both processes, one-off heatwaves, ‘losers’ ‘winners’, shape change structure functioning ecosystems.
