    Abstract

    Global marine habitats are increasingly threatened by the intensification of climate extremes, such as marine heatwaves (MHWs) and marine cold spells (MCSs). Brazil harbors diverse and endemic marine communities, yet the historical exposure of its coastal habitats to extreme events remains poorly quantified at local scales. Here we assess 40 years of MHWs and MCSs across eight coastal foundation habitats in Brazil using a validated, high-resolution composite sea surface temperature dataset covering over 100,000 sites. Events were characterized by their frequency, duration, and intensity, and classified into Moderate, Strong, Severe, and Extreme categories. We show a pronounced intensification of MHWs, with event frequency and duration increasing across most habitats and Strong events rising by nearly 190% over the past decade. More than half of habitat areas exhibit positive trends in both MHW frequency and duration, with the strongest increases observed in coral reefs (+ 1.5 events per decade; +3.5 days per decade) and seagrass meadows (+ 2.0 events per decade; +5.1 days per decade). In contrast, MCSs declined overall to roughly one-third of previous levels, yet record-intensity (− 4.5 °C) and exceptionally long-lasting (up to 160 days) cold events continue to punctuate the recent climate record in southern coastal habitats. Together, these results reveal strong spatial heterogeneity in exposure to climate extremes and establish a robust, site-specific baseline for assessing coastal ecosystem vulnerability under ongoing climate change.

    Abstract

    Three decades have passed since the first documented coral bleaching event in the Southwestern Atlantic Ocean. Rising sea surface temperatures continue to threaten coral conservation. Due to particular characteristics of Southwestern Atlantic coral communities, the influence of heat stress on bleaching events remains a challenge. Here, we review reports of coral bleaching over the past 30 yrs and their relationship to sea surface temperature anomalies. Coral bleaching reports were compiled from 1992 to 2022 and compared with bleaching predictions based on degree heating week (DHW) indices. Our results indicate that about 15% of the analyzed bleaching events were reported during periods of high DHW conditions. In contrast, 80% of these events occurred after 2010, coinciding with an average increase of 3  $$^{\circ }$$ C week in DHW values. These results support the expected increase in the influence of heat stress as one of the main causes of coral bleaching in recent years. In addition to a potential bias in bleaching reporting, corals near the coast between 3 $$^{\circ }$$ S–9 $$^{\circ }$$ S and 15 $$^{\circ }$$ S–18 $$^{\circ }$$ S appear to be historically most affected by heat stress events. Although no clear improvement in bleaching prediction performance was found by incorporating local SST variability into the DHW calculation, we suggest that extensive monitoring efforts could lead to a better understanding of this relationship under future climate change scenarios.

    <jats:title>Abstract</jats:title>
    <jats:p>The vertical turbulent flux, which comprises heat flux and vertical mixing, is one of key processes governing seawater temperature changes in the vertical direction. In this study, the influence of vertical turbulent flux on sea surface temperature (represented by a layer between the free-surface and approximately 20 m depth) in Indonesian seas was diagnosed from an eddy-permitting ocean modeling experiment result. The heat flux, as the sum of the net heat flux at the surface and penetrative shortwave radiation at the base of the surface layer, induced a net cooling tendency in both eastern and western Indonesia (represented by the Java Sea and Banda Sea, respectively). The cooling tendency due to the heat flux was opposed by the warming tendency induced by vertical mixing at the base of the surface layer, preventing excessive heat loss in the surface layer. An exception occurred during the Boreal Autumn in the Banda Sea, when the heat flux and vertical mixing resulted in warming and cooling tendencies, respectively. It was further found that the effect of vertical mixing on the surface layer heat budget was sensitive to the selection of the base layer depth, highlighting the mixing-related dynamic variation within the water column. In summary, this study provides additional insights into the near-surface dynamics that govern sea surface temperature seasonality in Indonesian Seas.</jats:p>

    <jats:p>Abstract. In mangrove forests, soil salinity is one of the most significant environmental factors determining forest distribution and productivity as it
    limits plant water uptake and carbon gain. However, salinity control on mangrove productivity through plant hydraulics has not been investigated by
    existing mangrove models. Here we present a new individual-based model linked with plant hydraulics to incorporate physiological characterization of
    mangrove growth under salt stress. Plant hydraulics was associated with mangroves' nutrient uptake and biomass allocation apart from water flux and
    carbon gain. The developed model was performed for two coexisting species – Rhizophora stylosa and Bruguiera gymnorrhiza – in a
    subtropical mangrove forest in Japan. The model predicted that the productivity of both species was affected by soil salinity through downregulation
    of stomatal conductance. Under low-soil-salinity conditions (&lt; 28 ‰), B. gymnorrhiza trees grew faster and suppressed the
    growth of R. stylosa trees by shading that resulted in a B. gymnorrhiza-dominated forest. As soil salinity increased, the
    productivity of B. gymnorrhiza was significantly reduced compared to R. stylosa, which led to an increase in biomass of
    R. stylosa despite the enhanced salt stress (&gt; 30 ‰). These predicted patterns in forest structures across the soil salinity
    gradient remarkably agreed with field data, highlighting the control of salinity on productivity and tree competition as factors that shape the
    mangrove forest structures. The model reproducibility of forest structures was also supported by the predicted self-thinning processes, which
    likewise agreed with field data. Aside from soil salinity, seasonal dynamics in atmospheric variables (solar radiation and temperature) were
    highlighted as factors that influence mangrove productivity in a subtropical region. This physiological principle-based improved model has the
    potential to be extended to other mangrove forests in various environmental settings, thus contributing to a better understanding of mangrove
    dynamics under future global climate change.

    The estimation of larval dispersal on an ecological timescale is significant for conservation of marine species. In 2018, a semi-population outbreak of crown-of-thorns sea star, <italic>Acanthaster</italic> cf. <italic>solaris</italic>, was observed on a relatively isolated oceanic island, Ogasawara. The aim of this study was to assess whether this population outbreak was caused by large-scale larval recruitment (termed secondary outbreak) from the Kuroshio region. We estimated larval dispersal of the coral predator <italic>A.</italic> cf. <italic>solaris</italic> between the Kuroshio and Ogasawara regions using both population genomic analysis and simulation of oceanographic dispersal. Population genomic analysis revealed overall genetically homogenized patterns among Ogasawara and other Japanese populations, suggesting that the origin of the populations in the two regions is the same. In contrast, a simulation of 26-year oceanographic dispersal indicated that larvae are mostly self-seeded in Ogasawara populations and have difficulty reaching Ogasawara from the Kuroshio region within one generation. However, a connectivity matrix produced by the larval dispersal simulation assuming a Markov chain indicated gradual larval dispersal migration from the Kuroshio region to Ogasawara in a stepping-stone manner over multiple years. These results suggest that the 2018 outbreak was likely the result of self-seeding, including possible inbreeding (as evidenced by clonemate analysis), as large-scale larval dispersal from the Kurishio population to the Ogasawara population within one generation is unlikely. Instead, the population in Ogasawara is basically sustained by self-seedings, and the outbreak in 2018 was also most likely caused by successful self-seedings including possible inbreeding, as evidenced by clonemate analysis. This study also highlighted the importance of using both genomic and oceanographic methods to estimate larval dispersal, which provides significant insight into larval dispersal that occurs on ecological and evolutionary timescales.

    <jats:p>Abstract. Seagrasses are marine flowering plants which are part of a highly productive coastal ecosystem and play key roles in the coastal processes. Unfortunately, they are declining in area coverage globally, and seagrass losses can be attributed to climate change such as sea-level rise, increase in sea surface temperature, and decrease in salinity, as well as human-related activities. The objective of this research is to assess the historical changes in the seagrass habitat and environment of Busuanga, Philippines using time series data available in the Google Earth Engine (GEE) platform. These include satellite data such as MODIS, Landsat 5, 7, and 8, and SeaWIFS. Reanalysis data such as HYCOM was also utilized in this research. Results from HYCOM data show that there has been a 0.0098 °C increase in the sea surface temperature per decade in Busuanga while MODIS data indicates an increase of 0.0045 °C per decade. Moreover, HYCOM data also shows an overall average of 0.76 mm in sea surface elevation anomaly and a decreasing trend in salinity values at 0.0026 psu per decade. Chlorophyll-a concentration has a minimal increase based on results from MODIS and SeaWIFS. Aside from changes in water parameters, changes in the land also affect seagrasses. Forest loss may cause increased siltation in the coastal ecosystem which can lead to seagrass loss. Based on the results of Landsat satellite image processing, there has been forest cover loss in Busuanga with the highest loss occurring in 2013 when super typhoon Yolanda ravaged the island. Lastly, results from the linear spectral unmixing of 778 Landsat images from 1987–2000 show that the average percent cover of seagrasses in Busuanga were declining through the years.

    As corals in tropical regions are threatened by increasing water temperatures, poleward range expansion of reef-building corals has been observed, and temperate regions are expected to serve as refugia in the face of climate change. To elucidate the important indicators of the sustainability of coral populations, we examined the genetic diversity and connectivity of the common reef-building coral Acropora hyacinthus along the Kuroshio Current, including recently expanded (<50 years) populations. Among the three cryptic lineages found, only one was distributed in temperate regions, which could indicate the presence of Kuroshio-associated larval dispersal barriers between temperate and subtropical regions, as shown by oceanographic simulations as well as differences in environmental factors. The level of genetic diversity gradually decreased towards the edge of the species distribution. This study provides an example of the reduced genetic diversity in recently expanded marginal populations, thus indicating the possible vulnerability of these populations to environmental changes. This finding underpins the importance of assessing the genetic diversity of newly colonized populations associated with climate change for conservation purposes. In addition, this study highlights the importance of pre-existing temperate regions as coral refugia, which has been rather underappreciated in local coastal management.

    PANGAEA - Data Publisher for Earth & Environmental Science   2009

    　More details

    Seven coral reef communities were defined on Shiraho fringing reef, Ishigaki Island, Japan. Net photosynthesis and calcification rates were measured by in situ incubations at 10 sites that included six of the defined communities, and which occupied most of the area on the reef flat and slope. Net photosynthesis on the reef flat was positive overall, but the reef flat acts as a source for atmospheric CO2, because the measured calcification/photosynthesis ratio of 2.5 is greater than the critical ratio of 1.67. Net photosynthesis on the reef slope was negative. Almost all excess organic production from the reef flat is expected to be effused to the outer reef and consumed by the communities there. Therefore, the total net organic production of the whole reef system is probably almost zero and the whole reef system also acts as a source for atmospheric CO2. Net calcification rates of the reef slope corals were much lower than those of the branching corals. The accumulation rate of the former was approximately 0.5 m kyr?1 and of the latter was ~0.7-5 m kyr?1. Consequently, reef slope corals could not grow fast enough to keep up with or catch up to rising sea levels during the Holocene. On the other hand, the branching corals grow fast enough to keep up with this rising sea level. Therefore, a transition between early Holocene and present-day reef communities is expected. Branching coral communities would have dominated while reef growth kept pace with sea level rise, and the reef was constructed with a branching coral framework. Then, the outside of this framework was covered and built up by reef slope corals and present-day reefs were constructed.

    We applied the proposed DNA analysis of benthic bacterial communities to 330 sediment samples collected from 77 sites along the coast of Japan (Hokkaido, Kashima-Nada/Kujukuri, Ariake Sea) to clarify the "regional characteristics," "spatial structure," and "temporal variability" of the benthic bacterial communities. We confirmed that the bacterial community in the bottom sediment has the diversity to express the differences hierarchically from the whole image to the detailed structure by changing the range of analysis “zooming”, and that it has the performance required for a broadband biosensor.

    It is considered that coral metabolic rates are greatly affected by flow conditions. However quantitative assessment of this factor is completely lacking. In this study, the net photosynthetic and respiration rates of corals and the thickness of the diffuse boundary layer (DBL) were investigated using micro-dissolved oxygen electrodes under controlled flow velocity in a recirculating aquarium. In this result, it is confirmed that DBL thickness was proportional to the -0.8 power of the mean flow velocity. This is consistent with the theoretical and semi-empirical relationships of previous works. This leads to the conclusion that the rate of mass exchange at the coral surface is proportional to the 0.8th power of the mean flow velocity. However, photosynthetic and respiration rates did not correlate well with flow velocity, suggesting that they may be limited mainly not by material transfer at the coral surface but by other metabolic factors of corals.

    Toward comprehensive evaluation of the long-term organic carbon (OC) sequestration by coastal vegetated habitats such as seagrass beds and mangroves, we developed a molecular-based technique to quantitatively evaluate the amount of OC exported from the habitats to the open ocean and sequestered in offshore sediment. We developed a real-time PCR technique for detecting DNAs from specific plant species to establish a method for rigorous quantification, and also attempted to convert DNA concentrations in sediments to OC concentrations derived from the same plant species. This method was then applied to several real offshore sediment samples, and used in conjunction with a model to estimate the sedimentation rate in the same zone, to finally enable estimation of the rate of sequestration of specific plant-derived OC into the sediment. The efficiency of the method was demonstrated through the case study conducted for offshore sediments around Okinawa Trough.

    Coral reefs are suspected to be particularly affected by the global warming and ocean acidification caused by the increase of atmospheric CO2 concentration. However, the seawater within Nikko bay at Palau was found to be warm and acidic, but hold high coral cover and high coral diversity. The high seawater pCO2 was found to be caused by the high seawater residence time of more than 2 months and affected by the calcification and decomposition by the organisms living within the bay. From transplantation and tank experiments, it was also found that the coral living within the bay are potentially acclimated to those environments fond within the bay, suggesting that corals may have the ability to adapt to high seawater pCO2 and temperature conditions.

    We developed the following methods and models; 1) accurate remote sensing methods for bathymetry and benthic covers in coral reefs, 2) a reef-scale bottom-up model based on the coral polyp model (Nakamura et al., 2013), 3) a model system incorporating a top-down effect by Acanthaster planci, 4) coral bleaching model which may be used for predicting the reef-scale resposes to higher thermal stresses due to global warming, 5) Runoff models for assessing terrestrial loads on coral reef ecosystems. We tried to apply innovative experimental and laboratory analysis methods for quntitatively demonstrating some important steps in the food web from basal resources to top level predators. By conducting field experiments using plates and others, we found two groups in the species having algal removal effects; one is the group grazing macroalgae and another is the group grazing microalgae on the plates.

    To elucidate the ‘vital effect’ of carbon stable isotope recorded in coral skeleton, carbon isotope module for incorporating to the coral polyp model which was already developed by Nakamura et al. (2013) was developed. The results of this model simulation were suggested that the vital effect of the carbon isotope is occurred by that the CO2 derived f. rom coral respiration was used calcification. Moreover similar annual patterns of δ13C in coral skeleton were reproduced by this model. This annual patterns are caused mainly by annual fluctuation of δ13C values in the coral tissue which are occurred by photosynthetic activity related to annual variation of the solar irradiance.

    The oxygen isotope systematics of dissolved phosphate was introduced for the first time as a novel technique to elucidate the dynamics and the provenance of one of the most important eutrophication agent, dissolved orthophosphate, in tropical coastal marine ecosystems. The magnitudes of isotope fractionation associated with phosphorus uptake by major primary producers such as hermatypic corals, seagrasses, seaweeds, and phytoplankton, were determined experimentally. It was demonstrated as a case study that the recycling from sediments of phosphate that had been accumulated by intensive mariculture activities during preceding decades is the principal cause for sustained eutrophication and extremely low N:P ratios observed in a coastal embayment of Bolinao, northern Philippines.

    Conducting international joint studies in Indonesia and Philippines, where blue carbon in coastal ecosystems has been rapidly decreasing due to degradation of the ecosystem, we could clarify carbon dynamics and associated ecosystem characteristics and material cycles in blue carbon ecosystems consisting of mangroves, seagrass and others in the joint study areas. We conducted also the development of various simulation models to analyze and predict blue carbon dynamics in an integrated atmosphere-land-ocean system, and remote sensing analyses. Based on all these results, we succeeded in developing a model system which would enable the future prediction of the changes in the carbon dynamics and the decrease in the blue carbon stock under global warming and other anthropogenic impacts.

    As a ‘comparative island study’, we conducted socio-economic surveys on livestock and tourism industry sectors for Ishigaki, Miyako and Yoron Islands in Japan and found that the structural features of the generation of environmental loads in each sector. We examined possible ways for controlling the environmental load generation based on the results of the surveys and a material flow analysis on the nitrogen from cattle farms. We made also various field measurements to clarify the propagation and material cycle processes of the environmental loads through surface and ground water flows and atmospheric precipitation. Moreover we developed computational models to quantitatively describe and predict the responses of coral reef and mangrove ecosystems under multiple environmental stresses.

    To clarify calcification mechanism of hermatypic corals, a coral polyp model under more realistic and comprehensive assumptions on physical, chemical and physiological processes was developed. The mechanism of “light-enhanced calcification” phenomenon was clarified by the model study, and the simulation result of the model well reconstructed the phenomenon. Moreover to shed light on the “vital effect” of the skeletal records of carbon stable isotope ratio, a carbon isotope module for the coral polyp model was developed and it was incorporated into the polyp model. The modified model reconstructed reasonable values and clear seasonal variations of skeletal carbon isotope ratio.

    サンゴ礁には様々な生物群集が生息し、それらは海岸とほぼ平行に帯状に分布している。この帯状分布は、岸から沖にかけての様々な物理・化学的な環境パラメータの勾配によって形成されていると考えられるが、その詳しい成因やメカニズムについてはまだ良く分かっていない。この環境勾配に伴ったこの空間的な群集の遷移メカニズムを理解することは、環境変動による時間的な群集遷移を理解する上でも重要である。そこで、本研究の目的は、サンゴ礁群集の帯状分布が、どのような物理・化学条件によって形成されるかを明らかにすることである。
    前年度は、今回サンゴ礁群集の分布がどのような環境パラメータによって規定されるかを検討するため、石垣島白保サンゴ礁域で礁を横断しながら海岸から50m～1000mまでを50m間隔で計6回採水を行い、温度、塩分、pH、アルカリ度および栄養塩類(全窒素、全リン、硝酸、亜硝酸、リン酸など)を測定した。また、平衡計算によりその他の炭酸系パラメータ(全炭酸、アラゴナイト飽和度、CO_2フガシティーなど)も求めた。本年度では、前年度に加えて、人為的な汚染が進んでいる轟川河口域にも測線を追加し、両測線のベルトトランゼクト法による群集調査と、両測線上50m間隔での採水を夏季4回、冬季4回行った。それらの結果、サンゴ礁生物群集は岸から沖に向かって帯状構造が確認されると供に、水温・塩分・栄養塩濃度等の環境パラメータは岸沖方向に明らかな勾配が生じていることが確認された。そこで、それらのデータを基に群集被度と環境パラメータとの関係を比較し、一般化線形モデルを用いて群集被度を環境パラメータの関数としてモデル化した。モデルにより再現された群集被度分布は、実際の被度の分布パターンを概ね良く再現することが確認された。
