Biological Impacts of Marine Heatwaves

Annual Review of Marine Science, Год журнала: 2022, Номер 15(1), С. 119 - 145

Опубликована: Авг. 17, 2022

Climatic extremes are becoming increasingly common against a background trend of global warming. In the oceans, marine heatwaves (MHWs)-discrete periods anomalously warm water-have intensified and become more frequent over past century, impacting integrity ecosystems globally. We review synthesize current understanding MHW impacts at individual, population, community levels. then examine how these affect broader ecosystem services discuss state research on biological MHWs. Finally, we explore emergent approaches to predicting occurrence andimpacts future events, along with adaptation management approaches. With further increases in intensity frequency projected for coming decades, MHWs emerging as pervasive stressors A deeper mechanistic their is needed better predict adapt increased activity Anthropocene.

Biodiversity, climate change, and adaptation in the Mediterranean

Ecosphere, Год журнала: 2022, Номер 13(4)

Опубликована: Апрель 1, 2022

Abstract Potential for, and limits to, adaptation to environmental changes are critical for resilience risk mitigation. The Mediterranean basin is a mosaic of biodiversity‐rich ecosystems long affected by human influence, whose now questioned climate change. After reviewing the different components biological adaptation, we present main characteristics marine terrestrial biodiversity in pressures they face. Taking climatic trends into consideration, discuss adaptive potential range dominated species without active dispersal. We argue that high heterogeneity landscapes seascapes constitutes laboratory study when conditions change rapidly may provide opportunities adaptability ecosystems. Adaptive management can should harness nature‐based solutions offered both ecological evolutionary processes increasing

Evolution of marine heatwaves in warming seas: the Mediterranean Sea case study

Frontiers in Marine Science, Год журнала: 2023, Номер 10

Опубликована: Июнь 30, 2023

Anomalous warming of the upper ocean is increasingly being observed in Mediterranean Sea. Extreme events, known as marine heatwaves (MHWs), can have a profound impact on ecosystems, and their correct detection characterization are crucial to define future scenarios. Here, we analyze MHWs over last 41 years (1982–2022) sea surface temperatures (SSTs). We show that intensification frequency, intensity, duration recent mainly due shift SST mean occurred two decades largely reduced when analyzing detrended data. Detrending thus allows use fixed climatology without overestimating MHW properties time distinguishes long-term (i.e., trend) from transient abrupt changes. Analogous results also found shorter temporal period, by 13 (2007–2020) situ data collected at different depths (5 40 m) Columbretes Islands. Additionally, analysis reveals atmospheric summer could affect layer 10 m depth. Lastly, catalogue major since 1982 presented. This evidences an exceptionally long-lasting intense MHW, starting May 2022 persisting, least, until end year, resulting event with highest cumulative intensity just after well-known 2003 event.

Marine protected areas in a changing ocean: Adaptive management can mitigate the synergistic effects of local and climate change impacts

Biological Conservation, Год журнала: 2023, Номер 282, С. 110048 - 110048

Опубликована: Апрель 20, 2023

During the last two decades, several Marine Heatwaves (MHWs) have affected coralligenous assemblages in Mediterranean Sea, causing catastrophic mass mortalities of habitat-forming species such as gorgonians, corals, and sponges. Even though Protected Areas (MPAs) are contributing to effectively protect marine ecosystems, impacts associated extreme climatic events within MPAs jeopardizing their protective role. Therefore, minimizing local stressors is crucial minimize interactive effects with global, more difficult manage, stressors. To address this, we assessed what extent regulation diving frequentation can support effective protection climate change, focusing on case study Medes Islands, which has recently suffered different global one most visited Sea. We combined 6 years demographic data red gorgonian Paramuricea clavata population modelling tools, explore long-term viability this managing schemes mortality scenarios. Overall, our results show that climate-adaptive management recreational activity under change enhance key octocoral, otherwise predicted go locally extinct at shallow depths (<25 m) next 20 years. This provides few attempts quantify an adaptive scheme may help delay a Area.

The Effect of Thermal Stress on the Physiology and Bacterial Communities of Two Key Mediterranean Gorgonians

Applied and Environmental Microbiology, Год журнала: 2022, Номер 88(6)

Опубликована: Фев. 2, 2022

In the Mediterranean Sea, tree-shaped gorgonian corals form large forests that provide a place to live for many species. Because of this important ecological role, it is crucial understand how common habitat-forming gorgonians, like Eunicella cavolini and Paramuricea clavata , are affected by high seawater temperatures expected in future due climate change.

Global patterns and drivers of genetic diversity among marine habitat‐forming species

Abstract Aim Intraspecific genetic diversity is one of the pillars biodiversity, supporting resilience and evolutionary potential populations. Yet, our knowledge regarding patterns at macroecological scales, so‐called macrogenetic patterns, remains scarce, particularly in marine species. Marine habitat‐forming (MHF) species are key some most diverse but also impacted ecosystems, such as coral reefs forests. We characterize drivers MHF provide a baseline, which can be used for conservation planning future monitoring programmes. Location Global. Time period Contemporary. Major taxa studied Bryozoans, hexacorals, hydrozoans, octocorals, seagrasses, seaweeds, sponges. Methods analysed database including estimates based on microsatellites more than 9,000 georeferenced populations from 140 species, belong to seven animal plant taxa. Focusing expected heterozygosity, we generalized additive models test effect latitude, taxon, status. tested correlation between richness diversity.

The accurate delimitation of species boundaries in nonbilaterian marine taxa is notoriously difficult, with consequences for many studies ecology and evolution. Anthozoans are a diverse group key structural organisms worldwide, but the lack reliable morphological characters informative genetic markers hampers our ability to understand diversification. We investigated population differentiation limits Atlantic (Iberian Peninsula) Mediterranean lineages octocoral genus
