Summary: This study examines the interconnection between the ecological and sedimentary processes of reef islands, focusing on Eva Island in Western Australia. The study reveals the unique sediment composition of molluscs and coral, suggesting a coupling between the source (reef) and sink (island) environments. The findings indicate that while Eva Island may be resilient to immediate climate change impacts, long-term resilience may be compromised due to reliance on sensitive sediment producing habitats and calcifying organisms.

Summary: The study reveals a lack of knowledge regarding sponges in the Mascarene Islands ecoregion, with only three calcareous sponge species previously identified in La Reunion. Through limited sampling efforts, 11 new calcareous sponge species were discovered, representing a significant increase in species diversity for the region. The proposed synonymization of the order Murrayonida with Clathrinida suggests a reclassification in sponge taxonomy based on the findings of this and previous studies.

Summary: Eddies in the southeast Indian Ocean play a role in modulating open ocean productivity, with their impact depending on their source and evolution. These eddies can stimulate and sustain phytoplankton, allowing their effects to persist over long distances. Measurements from autonomous floats show that chlorophyll and particulate organic carbon become concentrated at the base of the mixed layer as eddies are transported westward. The subsurface biomass maxima in both anticyclonic and cyclonic eddies remain active over several months, suggesting a mechanism for long-distance transfer of eddy plankton communities not captured by satellite remote sensing.

Summary: Tropical deep reefs (>30 m) are unique ecosystems with a wider geographic reach compared to shallow reefs, and they require explicit consideration in conservation and management activities. This study characterizes the benthic and fish communities in shallow and deep reefs in Seychelles, Western Indian Ocean, revealing distinct communities and traits dominating different depths. The results highlight the complexity of relationships between different biological components and the differences in reef resilience against disturbance or species invasions with depth.

Summary: Paleoclimate proxy data and model simulations suggest that the Indian summer monsoon was stronger during the Last Interglacial period than in the present day, attributed to orbital forcing and intensified land-sea contrast. Our study indicates that the enhanced inter-hemispheric thermal gradient during the Last Interglacial strengthened the Indian summer monsoon, contrary to the observed weakening under present-day warming.

Summary: Despite global interventions, climate change and biodiversity loss remain urgent environmental problems. Vulnerability to climate change is greater in the global south, especially in small island developing states (SIDS) that heavily rely on biodiversity. However, capacity and resources to address these challenges are often limited. Finding effective ways to simultaneously respond to climate change and conserve marine and coastal biodiversity is critical.

Summary: This paper studies the space-time variability of Surface Solar Radiation (SSR) over Reunion, a tropical island in the South-West Indian Ocean, and its modulation by climate variability. The study finds that nearby tropical cyclones can significantly reduce SSR, while synoptic convective regimes and intraseasonal Madden-Julian Oscillation have a relatively weaker impact on SSR.

Summary: The text discusses the dynamics of fluvial system evolution in relation to climatic variations and river processes, focusing on the factors influencing active braidplain widening in the High Arctic region and the forefields of retreating glaciers. The research findings suggest that the rate of active braidplain widening may decrease despite an increase in glacier ablation, and propose a model to predict areas prone to widening activity in high-latitude regions and arid intermountain basins.

Summary: The networks in the dorsal horn of the spinal cord play a crucial role in processing nociceptive information and shaping pain perception. Short-term plasticity of inhibitory connections, particularly in lamina II, can modulate the balance between excitation and inhibition, thus influencing pain transmission. This study showed that GABAergic interneurons in lamina II had target-specific and frequency-specific plasticity, with connections onto eGFP+ (putative excitatory) interneurons showing frequency-dependent depression and connections onto eGFP- (putative inhibitory) interneurons displaying limited frequency-dependent changes. These findings suggest that the modulation of inhibitory connections may be a potential target for pain relief strategies.

Summary: The dorsal horn of the spinal cord is involved in the integration of nociceptive messages. Plastic changes in the neuronal networks in the dorsal horn play a role in the development of analgesia, hyperalgesia, and allodynia in acute and chronic pain states. This study investigated the role of NMDA receptors in the modulation of GABAergic synaptic transmission in the dorsal horn network. The results showed that NMDA receptor activation facilitated spontaneous and miniature GABAergic synaptic transmission through a presynaptic mechanism of action, with a target specificity on GABAergic interneurons.

Summary: By using a filtration-sedimentation method, we improved the recovery of soil protist environmental DNA while reducing the co-extraction of non-target organisms. The method showed a 2-3 fold enrichment in shelled protists, with a decrease in fungi and plants. The findings suggest that this method can significantly enhance the resolution of soil protist diversity estimation in eDNA metabarcoding studies.
