“…Ocean warming due to elevated temperature results in phonological shifts in sea weeds globally (de Bettignies et al, 2018). Elevated temperature adversely influences the activity of coralline algae (Page et al, 2021). Studies conducted reveals that elevated temperature has considerable effects on cyanobacterial growth and development (Deng et al, 2021).…”

Plant mutualistic association with various beneficial microbes is referred to as the plant enhancer microbiome. These microbes are found either in episphere or endosphere of the plant tissues. Several pieces of evidence have highlighted that plant microbiomes and soil play a pivotal role in making soil nutrient balance which is readily available to plants and provide strength under various stresses. Recently different technologies relevant to plant microbiome and diversity such as sequencing technologies, metagenomics, and bioinformatics have been utilized. Knowledge about factors that shape the composition of plant microbes is still less explored. Here, current insights into the issues driving the above/below plant microbial diversities are explored. Primarily, we address the distribution of microbial communities above and below ground across plant habitats that has benefitted plants. Microbial communities are efficient regulators of biogeochemical cycle which is a better approach to mitigate changing climatic patterns aids in proper utilization of greenhouse gases for their metabolic mechanisms. The present review is thereby significant for assessing microbiome mitigation toward climate change and multiple avenues of plant- microbe interaction under commuting climatic scenario. Finally, we summarize factors that promote the structure and composition of the plant microbiome.

Impacts of ocean warming on a reef-building coralline alga Amphiroa cf. fragilissima under high irradiance

Coralline algae, an important calcifying group, play vital roles in the primary productivity, reef frameworks construction, and carbon store. In this study, we investigated the responses of an articulated coralline alga Amphiroa cf. fragilissima to ocean warming under various light intensities. The relative growth rate significantly decreased under light or heat stress. When A. cf. fragilissima was exposed to high light intensity (120 μmol photons m−2 s−1) at 32°C, the relative growth rate was lowest, which reduced by 87% compared with that of group A1 (60 μmol photons m−2 s−1, 26°C). Meanwhile, a higher level of algal bleaching occurred when light intensity was 120 μmol photons m−2 s−1. Similarly, Fv/Fm and Chl-a content were negatively affected by light and heat stress, but they were more affected by light. Furthermore, the mineralogical responses to temperature and light were investigated. The net calcification rate declined from 92.27 (60 μmol photons m−2 s−1, 26°C) to 10.92 μmol CaCO3 g−1 DW day−1 (120 μmol photons m−2 s−1, 32°C). High temperature significantly decreased Ca content in live algal pigmented layer, whereas there were no significant differences in Ca content in the skeleton layer, implying that the pigmented layer could protect skeleton layer from mineral changes under ocean warming. The results revealed that A. cf. fragilissima was impaired by high light or thermal stress from various aspects, including growth, survival, photosynthesis, reproduction, and calcification. This study contributes to understand the effects of warming and light on coralline algae and provides a theoretical basis to protect the richness and diversity of calcified macroalgae.

“…Once in operation, the LNG port will probably increase the temperature of the surrounding water due to thermal discharge from the port's power station (see port layout in Figure S5). Given that prolonged elevation in water temperature can reduce CCA's tolerance to acute thermal stress (Page et al, 2021), thermal discharge from the LNG port will probably make CCA in the TAR more vulnerable to extreme weather events (such as heat waves), which may become increasingly frequent due to climate change (Oliver et al, 2018). Further, the LNG port will act like groins, altering sedimentation, nearshore currents, and sand scouring in the coastal area; in turn, these environmental changes may affect the growth of CCA in the TAR, probably in damaging ways.…”

Geographic distance, sedimentation, and substrate shape cryptic crustose coralline algal assemblages in the world’s largest subtropical intertidal algal reef

et al. 2022

Algal reefs, concreted by crustose coralline algae (CCA), are the main biotic reefs in temperate waters but rare in the subtropics and tropics. The world's largest known intertidal algal reef in the subtropics is the Taoyuan Algal Reef (TAR) located in the northwestern coast of Taiwan. The biodiversity and ecology of the TAR are scarcely explored, and now the reef is imperiled by industrialization. Here, we document cryptic species of CCA in Taiwan, particularly the TAR, by sequencing the psbA genes of over 1800 specimens collected across Taiwan. We also examine the ecological background of the TAR by surveying its benthic composition and measuring its environmental parameters. Our data reveal that the TAR harbours a high diversity of cryptic CCA species (27 molecular operational taxonomic units, or mOTUs), many of which are potentially new to science (18 mOTUs) and/or endemic to the TAR (9 mOTUs).Comparing the CCA species inventory of the TAR with the rest of Taiwan shows that the TAR represents a unique hotspot of CCA taxa in the waters of Taiwan. Our analyses show that variation in the CCA assemblages in the TAR is associated with geographic distance, sedimentation, and substrate type (for example, reef vs. hermit crab shell), suggesting that dispersal limitation and contemporary environmental selection shape the CCA assemblages in the TAR. The data from this study can inform the monitoring of human impacts on the health of the TAR and contribute to our understanding of the ecological processes underlying algal reef development.
