Among abiotic stresses, heat stress is described as one of the major limiting factors crop growth worldwide, high temperatures elicit a series physiological, molecular, and biochemical cascade events that ultimately result in reduced yield. There growing interest among researchers use beneficial microorganisms. Intricate highly complex interactions between plants microbes alleviation stress. Plant–microbe are mediated by production phytohormones, siderophores, gene expression, osmolytes, volatile compounds plants. Their interaction improves antioxidant activity accumulation compatible osmolytes such proline, glycine betaine, soluble sugar, trehalose, enriches nutrient status stressed Therefore, this review aims to discuss response understand mechanisms microbe-mediated on physio-molecular basis.

A marine heatwave drives significant shifts in pelagic microbiology

Communications Biology, Journal Year: 2024, Volume and Issue: 7(1)

Published: Jan. 24, 2024

Abstract Marine heatwaves (MHWs) cause disruption to marine ecosystems, deleteriously impacting macroflora and fauna. However, effects on microorganisms are relatively unknown despite ocean temperature being a major determinant of assemblage structure. Using data from thousands Southern Hemisphere samples, we reveal that during an “unprecedented” 2015/16 Tasman Sea MHW, temperatures approached or surpassed the upper thermal boundary many endemic taxa. Temperate microbial assemblages underwent profound transition niche states aligned with sites over 1000 km equatorward, adapting higher lower nutrient conditions bought by MHW. MHW also modulate seasonal patterns diversity support novel compositions. The most significant affects MHWs occurred warmer months, when exceeded climatological bounds. Trends in response across several different locations suggest these emergent properties temperate warming, which may facilitate monitoring, prediction adaptation efforts.

Sea otter recovery buffers century-scale declines in California kelp forests

PLOS Climate, Journal Year: 2024, Volume and Issue: 3(1), P. e0000290 - e0000290

The status of kelp forests and their vulnerability to climate change are global significance. As the foundation for productive extensive ecosystems, understanding long-term forest trends is critical coastal ecosystem management, resiliency, restoration programs. In this study, we curate historical US government canopy inventories, develop methods compare them with contemporary surveys, use a machine learning framework evaluate rank drivers California over last century. Historical surveys documented Macrocystis Nereocystis covered approximately 120.4 km 2 in 1910–1912, which only slightly above 2014–2016 (112.0 ). These statewide comparisons, however, mask dramatic regional changes increases Central (+57.6%, +19.7 ) losses along Northern (-63.0%, -8.1 ), Southern (-52.1%, -18.3 mainland coastlines. Random Forest models sea otter ( Enhydra lutris nereis population density as primary driver changes, benthic substrate, extreme heat, high annual variation productivity also significant. This century-scale perspective identifies dramatically different outcomes California’s forests, providing blueprint nature-based solutions that enhance resilience change.

Global research priorities for historical ecology to inform conservation

Endangered Species Research, Journal Year: 2024, Volume and Issue: 54, P. 285 - 310

Historical ecology draws on a broad range of information sources and methods to provide insight into ecological social change, especially over the past ∼12000 yr. While its results are often relevant conservation restoration, insights from diverse disciplines, environments, geographies have frequently remained siloed or underrepresented, restricting their full potential. Here, scholars practitioners working in marine, freshwater, terrestrial environments 6 continents various archipelagoes synthesize knowledge fields history, anthropology, paleontology, with goal describing global research priorities for historical influence conservation. We used structured decision-making process identify address questions 4 key priority areas: (1) concepts, (2) co-production community engagement, (3) policy management, (4) climate change impacts. This work highlights ways that has developed matured use novel sources, efforts move beyond extractive practices toward co-production, application management challenges including change. demonstrate this field brought together researchers across connected academics practitioners, engaged communities create apply our shared future.

Resistance of Posidonia oceanica seedlings to warming: Investigating the importance of the lag-phase duration between two heat events to thermo-priming

Marine Pollution Bulletin, Journal Year: 2024, Volume and Issue: 204, P. 116515 - 116515

Published: May 25, 2024

The increase of marine heat waves (MHWs) occurrence is exacerbated in Mediterranean Sea and temperature resilience-enhancing strategies on key species, such as the seagrass Posidonia oceanica, need to be investigated. "Priming" describes a stimulus that prepares an organism for improved response upcoming environmental changes by triggering memory remains during lag-phase. aim this study, conducted Sardinia (Italy), was investigate whether development thermo-primed P. oceanica seedlings affected field simulated MHW depending duration After thermo-priming stimulus, had 0, 7 or 14 days lag-phase after that, each group, half experienced (the other served controls). Some did not experience either priming Results show any evidence triggered but they highlighted importance acclimation phase before highest temperature: gradual higher number leaves shorter leaf necrosis length compared between two events. Regardless MHWs slowed down root length. Considering fluctuations, testing different intensities necessary provide information about adaptive success species.

Global Trends in Marine Heatwaves and Cold Spells: The Impacts of Fixed Versus Changing Baselines

Abstract Marine heatwaves (MHW) and cold spells (MCS) are considered to be anomalously warm or cool events in sea surface temperature that commonly defined relative a long‐term fixed baseline. As result, because of climate warming, it is often concluded MHW will become stronger, longer, more frequent the future, whereas MCS weaker, shorter, less frequent. Here, argued order understand physics MHW/MCS, important remove signal when detecting events. The 1982–2021 National Oceanic Atmospheric Administration optimum interpolation data set (NOAA OISST V2) used show using baseline leads on average overestimating underestimating strengths between 1982 2021 compared linear trend signal.

Abstract. Marine heatwaves (MHWs) induce significant impacts on marine ecosystems. There is a growing need for knowledge about extreme climate events to better inform decision-makers future climate-related risks. Here we present unique observational dataset of MHW macroevents and their characteristics over the southern Europe western Asian (SEWA) basins, named SEWA-MHW (https://doi.org//10.5281/zenodo.7153255; Bonino et al., 2022). The derived from European Space Agency Sea Surface Temperature Climate Change Initiative (ESA SST CCI) v2 dataset, it covers 1981–2016 period. methodological framework used build novelty this work. First, MHWs detected in each grid point ESA CCI are relative time-varying baseline climatology. Since intrinsic fluctuation anthropogenic warming redefining mean climate, considers both trend seasonal cycle. Second, using connected component analysis, space time aggregated order obtain macroevents. Basically, macroevent-based obtained cell-based without losing high-resolution (i.e., cell) information. can be many scientific applications. For example, identified phases well-known summer 2003, taking advantage statistical clustering methods, clustered largest SEWA basins based shared metrics characteristics.
