Offshore windfarms (OWFs) constitute a rapidly expanding source of renewable energy that inevitably affects marine biodiversity, especially those built within critical areas for biodiversity conservation. To understand the potential effect of OWFs on bird communities, we systematically tracked bird communities and their behavior within OWFs near the Migratory Bird Sanctuaries along the Coast of the Yellow Sea in China from 2020 to 2022 using voyage investigations. The results indicated that bird diversity was greater within OWFs than in seawaters away from the OWFs.

N-methyladenosine (m6A) modification is a prevalent mRNA modification that regulates diverse biological processes in eukaryotes, including immune responses. While the role of m6A in mammalian immunity has been explored, its involvement in the immune defense of invertebrates, particularly marine bivalves which face constant pathogen challenges, remains largely unknown. Here, we investigated the function of methyltransferase-like 3 (METTL3), a key m6A "writer" enzyme, in the immune response of the marine bivalve Mytilus coruscus against Vibrio alginolyticus infection.

Ensemble habitat suitability model predicts Suaeda salsa distribution and resilience to extreme climate events.

J Environ Manage

January 2025

State Environmental Protection Key Laboratory of Coastal Ecosystem, National Marine Environmental Monitoring Center, Dalian, 116023, China. Electronic address:

Climate anomalies lead to an increased occurrence of extreme temperature and drought events in coastal wetlands, resulting in heightened survival pressure on salt marsh plants. It is imperative to anticipate the effects of these events on the habitat suitability and resilience of coastal salt marsh vegetation to inform restoration efforts and management strategies. Herein, an ensemble model was developed to evaluate the recovery of Suaeda Salsa in the two subsequent years following the anomalously high temperatures and decreased precipitation experienced during the summer of 2018, potentially leading to a decline in this species in the eastern coast of Liaohe Estuary wetland (Bohai Sea, China).

This study investigates the process of synthesizing eco-cement clinker using recycled powdered glass (RPG) and oyster shell residue (OSHL) as primary raw materials. Analysis of the mineral composition of RPG revealed that it primarily consists of silica and contains a high level of alkali metal oxides, while OSHL comprises a high-purity trigonal calcite structure, similar in chemical composition to limestone. Comparative analysis of the synthesized ecological cement and its hydration products showed that, after heat treatment at 1200 °C, the alkali metal content in the H12 sample significantly decreased, thereby meeting the standards for cement raw materials.
