This convergent mixed methods study examined the impact of a new phenomena based (PhBL) lesson plan—grounded by social constructivism and the NGSS framework—on 1) student ability to explain and contextualize a phenomenon, and 2) assess student perceptions of PhBL compared to traditional science instruction. This addressed the shift towards science education reform that better prepares […]

A key seawater acidification-enriched gut bacterium, Pseudoalteromonas carrageenovora P1, enhances growth performance, antioxidant status, and disease resistance in sea cucumbers under seawater acidification

Highlights Abstract The sea cucumber (Apostichopus japonicus) is a key mariculture species of high economic value in East Asia. However, Ocean acidification, resulting from the increased uptake of anthropogenic CO₂ by seawater, severely impairs its growth, survival, and reproductive performance, thereby threatening the sustainable development of this aquaculture industry. The gut microbiota play a critical […]

Submarine groundwater discharge drives massive carbon outwelling and impacts ocean acidification buffering in a mangrove-dominated bay of the Beibu Gulf, China

bmari2d039bf8b4 — Mon, 28 Sep 2026 11:59:00 +0000

Mangrove ecosystems are critical blue carbon sinks, yet the role of submarine groundwater discharge (SGD) in carbon outwelling and coastal acidification buffering remains a major knowledge gap. This study integrates radium isotopes (224Ra and 228Ra) and carbonate system parameters to quantify SGD-driven carbon fluxes and their impacts on ocean acidification buffering in Tieshan Bay, a […]

The spatial and temporal variability physicochemical seawater parameter in Dangli Island of Langkawi, Malaysia

bmari2d039bf8b4 — Mon, 28 Sep 2026 11:58:00 +0000

Marine environments that are subjected to seasonal changes are increasingly exposed to various factors, such as water pollution, climate change, coastal development, and human impacts. Therefore, this study examined seasonal changes in the main physicochemical parameters of seawater around Dangli Island, Langkawi, Malaysia to better understand the environmental conditions that affect the local marine ecosystem. […]

Thermal history and behavioural plasticity shape reef fish tolerance to marine heatwaves

bmari2d039bf8b4 — Fri, 25 Sep 2026 12:00:00 +0000

Marine heatwaves are becoming more frequent and intense, driving mass fish mortalities and reshaping marine ecosystems, yet the capacity of fishes to tolerate heatwaves remains unclear. We quantified physiological condition and behavioural responses of juvenile warm-water (Abudefduf vaigiensis) and cool-water (Microcanthus strigatus) fishes from three natural climate analogues—an ambient temperate reef, an ocean warming analogue, […]

Substrate stability drives zoobenthic recruitment in sessile polychaetes in interstitial marine habitats

bmari2d039bf8b4 — Fri, 25 Sep 2026 11:59:00 +0000

Early life stages play a key role in structuring marine benthic communities, yet the mechanisms controlling recruitment in confined habitats remain poorly understood. In particular, the relative importance of substrate stability and visual cues under low-exchange, low-light conditions is unresolved. We investigated zoobenthic recruitment on 8 natural rock types differing in mineral composition, grain size, […]

Projecting the impact of climate change on the lipid profile of the hydrocoral Millepora alcicornis: Relative lipid homeostasis under warming and ocean acidification

bmari2d039bf8b4 — Fri, 25 Sep 2026 11:58:00 +0000

Climate change exerts a strong impact on marine ecosystems, particularly through ocean acidification and rising water temperatures. Within this context, shifts in lipid composition have emerged as valuable stress indicators in many organisms, providing insights into the trophic ecology of ecosystems. The objective of this study was to assess the combined effects of warming and […]

Effect of increased carbon dioxide on copper-induced olfactory dysfunction in aquatic animals

bmari2d039bf8b4 — Thu, 24 Sep 2026 11:59:00 +0000

Copper contamination and rising atmospheric CO2, which lowers pH through acidification. Because copper becomes more toxic at lower pH, acidification may make copper more harmful than current water quality guidelines predict. Northern Clearwater crayfish (Faxonius propinquus) and zebrafish (Danio rerio) were exposed to a range of copper concentration under current atmospheric CO2 to identify the […]
