Ecophysiological responses to heat waves in the marine intertidal zone

Journal of Experimental Biology, Год журнала: 2025, Номер 228(2)

One notable consequence of climate change is an increase in the frequency, scale and severity heat waves. Heat waves terrestrial habitats (atmospheric waves, AHW) marine (marine MHW) have received considerable attention as environmental forces that impact organisms, populations whole ecosystems. Only one ecosystem, intertidal zone, experiences both MHWs AHWs. In this Review, we outline range responses zone organisms exhibit response to We begin by examining drivers thermal maxima develop a simple model daily maximum temperatures based on publicly available tide solar radiation models, compare it with logged, under-rock temperature data at site. then summarize experimental ecological studies how ecosystems respond across dimensions biotic response. Additional paid impacts extreme cellular physiology, including oxidative stress thermally induced mitochondrial overdrive dysfunction. examine energetic consequences these mechanisms they shift organismal traits, growth, reproduction immune function. conclude considering important future directions for improving organisms.

Environmental acclimatization of the relatively high latitude scleractinian coral Pavona decussata: integrative perspectives on seasonal subaerial exposure and temperature fluctuations

Coral reefs are being increasingly threatened due to global climate change. However, some coral species have shown strong tolerance despite living in marginal environments. The Pavona decussata from Weizhou Island the South China Sea experiences subaerial exposure summer and winter extreme low tides, their environmental acclimatization this aerial remains unexplored. Here we aimed explore molecular mechanism of P. under season or background through physiological multi-omics integrative analyses. Specifically, corals with a history seasonal air underwent comprehensive changes energy metabolism defense mechanisms compared permanently submerged corals. In summer, experiencing enhanced antioxidant by increasing activities enzymes T-SOD CAT, coral-associated bacterial community shifted toward class Alphaproteobacteria that may provided resistance stresses. Moreover, decrease transcript levels TCA cycle increase metabolite content ornithine suggested an alteration metabolic pathways. Corals air-exposed reserves winter, as indicated higher Chl rebound Gammaproteobacteria. Furthermore, accumulation leukotriene D4 activation TGF-beta signaling pathway anti-inflammatory requirements positive regulation innate immunity.

Short-term thermal acclimation improved the thermal tolerance of three species of scleractinian corals in the South China Sea

Journal of Sea Research, Год журнала: 2024, Номер 199, С. 102505 - 102505

Investigating the potential and mechanisms of thermal adaptability in scleractinian corals is critical for aiding dealing with global warming improving efficiency coral reef restoration efforts. Although acclimation facilitates resistance branching to stress, little known about physiological processes massive platy South China Sea or their ability adapt heat stress. In this study, we conducted indoor short-term simulation experiments on three types corals: Porites lutea, Pavona decussata, Pocillopora damicornis. Subsequently, studied responses adaptive stress explored effects using biochemical markers. The results showed that exhibited comparable phenotypic including tentacle retraction decreases zooxanthellae density, maximum quantum photosystem II, glutathione content, along increases antioxidant activity (catalase superoxide dismutase), ammonium assimilation (glutamine synthetase), apoptosis (lipid peroxide caspase-3). Additionally, tolerance differed among different species coral. Furthermore, markers performed better all after acclimation, decreased from P. lutea damicornis decussata. We propose enhances by affecting metabolism capacity. Leveraging efforts could help threats posed enhance efficiency.
