A significant dieback event of Avicennia marina was observed in the coastal area East Lampung, beginning 2020, with its cause remaining unidentified. This study aimed to assess rate mangrove degradation and investigated influence ocean index on event. Sequential satellite imagery analysis (2019–2022) performed evaluate changes cover, focusing a 200-hectare within total 528.69-hectare forest, utilizing using Normalized Difference Vegetation Index (NDVI) Mangrove Health (MVI). Field data were collected at 30 research stations, encompassing live mangroves, partially affected areas, fully sites, both before during (2020 2021). These efforts provide critical insights into extent drivers decline region. Based results, caused rapid loss healthy stands (results MVI) very-high-density NDVI). With reduction 117.64 ha 2020-2021. pronounced 2021 coincided prolonged La Niña phase, leading excessive freshwater influx inundation, which likely decreased salinity sediment dynamics required for survival. Additionally, negative ENSO phase (-1.2) concurrent positive IOD (+1.5) associated increased drought conditions, elevated salinity, reduced availability, further stressing populations. findings underscore strong link between oceanic variability health, highlighting need continued monitoring improved predictive models long-term impacts climate change ecosystems.

Mangroves, tidal marshes, and seagrasses have been recognized as blue carbon coastal ecosystems they accommodate large stocks, enable long-term storage, the capacity to control greenhouse gas emissions possess potential reduce rise in atmospheric CO2 levels. In tropical subtropical intertidal zones, mangroves show significant productivity rapid deposition rates. Mangroves play an important role capturing, transforming, storing atmosphere into sediments for a long time displacing organic from zone offshores ocean. also help preventing storms, hurricanes, erosion, waves. Recently, threatened natural anthropogenic activities such urbanization, pollution, aquaculture tourism. They are expected hamper their essential services, defense, breeding grounds aquatic organisms' seafood supply, etc. Despite importance of mangrove forests sequestration well numerous goods services offer humans, including wood non-wood forest products, food, fisheries, medicines, eco-tourism, recreation. These deteriorating at alarming rates, necessitating immediate intervention. Thus, protection, restoration conservation this ecosystem gaining considerable attention researchers across globe. This paper provides information on different adaptations, mechanisms, roles ecosystem, estimation, influencing factors, threats, strategies invaluable habitat.

Fireflies are a diverse group of bioluminescent beetles belonging to the family Lampyridae. Recent research on their diversity, evolution, behavior and conservation has greatly advanced our scientific understanding these charismatic insects. In this review, we first summarize new discoveries about taxonomic ecological then focus recent endeavors identify protect threatened fireflies around world. We outline main threats linked population declines (habitat loss degradation, light pollution, pesticide overuse, climate change tourism) describe relevant risk factors that predict which species will be particularly vulnerable threats. Although global coordination firefly efforts begun only recently, considerable progress already been made. work by IUCN SSC Firefly Specialist Group currently facing elevated extinction risks devise strategies them. To date, Red List assessments have completed for 150 taxa, 20% face heightened risks.

Mangrove ecosystems are increasingly threatened by climate change and coastal development, making precise ecological stress modeling essential for informing conservation strategies. This study employs AI-based classification techniques to classify mangroves using Landsat 8-SR OLI/TIRS sensors (2023) along the Jazan Coast, identifying a total mangrove area of 19.4 km2. The ensemble classifier achieved an F1 score 95%, overall accuracy 93%, kappa coefficient 0.86. Ecological was modeled via generalized additive model (GAM) with key predictors, including trends in NDVI, NDWIveg (vegetation water content), NDWIow (open water), LST from 1991 2023, which were derived surface reflectance (SR) products 5 TM, 7 ETM+, 8 sensors. exhibited strong performance, R2 0.89. Model diagnostics linear regression (R2 = 0.86), high F-statistic, minimal intercept, 10-fold cross-validation confirmed model’s robustness, consistent MSE (0.12) cross-validated Moran’s I analysis also indicated significant spatial clustering. Findings indicate that non-ravine, mainland areas experience more disruptions freshwater sediment supply due recent developments. In contrast, island exhibit low levels human activity, except dense canopy regions where stress, likely linked change, observed. These results underscore need further investigation into drivers this pressure.
