Coral reefs provide ecosystem benefits to millions of people but are threatened by rapid environmental change and ever-increasing human pressures. Restoration is becoming a priority strategy for coral reef conservation, yet implementation remains challenging it increasingly apparent that indirect conservation restoration approaches will not ensure the long-term sustainability reefs. The important role conditions in practice currently undervalued, carrying substantial implications success. Giving paramount importance conditions, particularly during pre-restoration planning phase, has potential bring about considerable improvements innovation. This Essay argues risk may be reduced adopting an environmentally aware perspective gives historical, contemporary, future context decisions. Such approach open up new opportunities with improved have capacity dynamically respond trajectories.

Slight thermal stress exerts genetic diversity selection at coral (Acropora digitifera) larval stages

BMC Genomics, Год журнала: 2025, Номер 26(1)

Abstract Background Rising seawater temperatures increasingly threaten coral reefs. The ability of larvae to withstand heat is crucial for maintaining reef ecosystems. Although several studies have investigated larvae’s genetic responses thermal stress, most relied on pooled sample sequencing, which provides population-level insights but may mask individual genotype variability. This study uses larval sequencing investigate genotype-specific stress and the selective pressures shaping their genomes, offering finer resolution deeper insights. Results investigates response before acquiring symbiotic algae, aiming elucidate relationship between diversity stress. Larvae sourced from eight Acropora digitifera colonies were subjected ambient temperature (28 °C) conditions (31 °C). impact was assessed through sequencing. While overall diversity, represented by π, did not significantly differ control heat-exposed groups, Tajima’s D differed, indicating different in each group. genomic regions under higher lower broadly shared among head conditions, implying that operated distinctive manners. Many protein-coding sequences identified this region, codon evolution many these genes showed signs positive selection. These results highlight complex temperatures. showing selection also been influenced historical fluctuations, as suggested association with loci during Acroporid speciation. codon-level speciation potential role adaptation environmental changes over evolutionary timescales. Conclusion findings underscore significance reproduction They indicate even minor can exert significant pressure, potentially leading profound implications research understanding rising

The acute and chronic low-temperature stress responses in Porites lutea from a relatively high-latitude coral reef of the South China Sea

Frontiers in Marine Science, Год журнала: 2024, Номер 11

Relatively high-latitude coral reefs could be potential “refuges” for corals under climate change. One of the most important aspects limiting their availability as refuges is low-temperature stress. However, mechanisms underlying response holobionts to stress unclear. In this study, we aimed explore by recording maximum quantum yields photosystem II ( Fv/Fm ) and transcriptome responses Porites lutea acute (1–2 weeks) chronic (6–12 at 20°C 14°C. The P. samples were collected from a relatively reef in South China Sea (109°00′–109°15′E 21°00′–21°10′ N). study suggested that: (1) Under stress, Symbiodiniaceae dropped 64%, which was significantly higher than 49% observed Low-temperature inhibited II(PSII) functioning, with greater inhibition (2) Downregulation sugar metabolism-related genes implied that decrease energy due obstruction PSII.

Conservation and management of endangered species are crucial to reveal the restriction mechanisms climate change on distribution pattern species. Due human interference a limited natural capacity for regeneration, wild resources Ormosia microphylla Merr. & H. Y. Chen have progressively dwindled. Therefore, this study reconstructed historical migration dynamics geographical O. since last interglacial period analyzed its adaptation climatic conditions, aiming provide an important reference protection microphylla. Using data from 40 nine factors, optimized MaxEnt model, in conjunction with ArcGIS 10.4.1 software, was used predicting visualizing ranges associated changes under historical, current, future scenarios. This analysis also determine dominant factors constraining The results show that contemporary suitable habitats primarily concentrated mountainous regions southern China, including Fujian, Guangdong, Guangxi, Guizhou. precipitation driest quarter (bio17), temperature seasonality (bio4), min coldest month (bio6), elevation (elev) were key limiting current In SSP126 SSP585 scenarios, total area showed downward trend. spatial shows increase is less than loss different scenarios future.

Acute heat priming promotes short-term climate resilience of early life stages in a model sea anemone

PeerJ, Год журнала: 2023, Номер 11, С. e16574 - e16574

Across diverse taxa, sublethal exposure to abiotic stressors early in life can lead benefits such as increased stress tolerance upon repeat exposure. This phenomenon, known hormetic priming, is largely unexplored stages of marine invertebrates, which are increasingly threatened by anthropogenic climate change. To investigate this larvae the sea anemone and model invertebrate Nematostella vectensis were exposed control (18 °C) or elevated (24 °C, 30 35 39 temperatures for 1 h at 3 days post-fertilization (DPF), followed return °C). The animals then assessed growth, development, metabolic rates, heat 4, 7, 11 DPF. Priming intermediately augmented growth development compared controls priming °C. Indeed, °C hampered developmental progression, with around 40% still planula stage DPF, contrast 0% all other groups. Total protein content, a proxy biomass, respiration rates not significantly affected suggesting resilience. Heat was quantified acute exposures, higher primed intermediate those time points. possible molecular mechanism observed changes tolerance, expression shock 70 (HSP70) Expression HSP70 increasing temperature, presence doublet band persistent negative effects on homeostasis. Interestingly, second cohort cultured 6 weeks continued display responses, whereas lost; contrast, short-term extreme (39 persisted. These results demonstrate that some dose-dependent waned over while others persisted, resulting heterogeneity organismal performance across ontogeny following priming. Overall, these findings suggest may augment resilience via modulation key physiological phenotypes, also affirming need limit further ocean warming.
