Summary: During the global COVID-19 pandemic, the eruption of Piton de la Fournaise on Réunion Island, France provided the volcano observatory with the opportunity to demonstrate its capability in managing volcanic crises remotely. They successfully utilized remote monitoring networks to monitor the eruption, ensuring the continuity of monitoring duties and updates despite the challenges posed by the double crisis of volcanic eruption and health pandemic.

Summary: This study uses DInSAR measurements to investigate the ground displacements during the eruption of Piton de la Fournaise volcano in 2019. The results reveal the presence of five volcanic sources that correlate well with the location of the fissures, seismic activity, and known geophysical evidence.

Summary: The study found that even low levels of land use change can alter species composition and reduce species diversity in bird communities. While overall functional diversity and phylogenetic diversity were similar across land use types, there were significant contractions in trophic and locomotory trait structures of bird communities in restored areas and cultivated areas. Soil moisture, elevation, and lower vegetation height were major factors influencing taxonomic, functional, and phylogenetic dimensions of bird communities.

Summary: Research has shown the need to strengthen knowledge exchange and collaborative research to accelerate the adaptation and implementation of promising interventions in the field of childhood obesity. The National Institutes of Health (NIH) gathered researchers from the United States and Latin America to highlight synergies between studies in Latin America and those conducted in Latino populations in the U.S., aiming to catalyze new relationships and identify common research questions and strategies.

Summary: In this study, the Bellecombe products were investigated using various techniques to characterize the evolution of the magmatic system feeding the eruptive activity in Piton de la Fournaise. The results suggest that the lava flows share a geochemical affinity with the main series documented at the volcano, indicating the dynamic activity of the plumbing system in the recent past.

Summary: La Reunion Island is home to two major volcanic systems with Piton de la Fournaise being a highly active shield volcano. In 2007, a small amount of silica-rich pumice was erupted during its largest historical eruption, indicating a genetic relationship to the mantle plume. The study suggests a long and complex history of differentiation and outgassing in the feeding system of this volcano.

Summary: This study emphasizes the importance of restoring faunal diversity and functional traits in rainforest habitats degraded by anthropogenic fires. While there are differences in species composition between primary forest and regenerating forest, taxonomic diversity remains similar across restoration approaches. Preventing anthropogenic fires is key in promoting avian diversity in tropical rainforests.

Summary: The oxygen fugacity (fO(2)) in mantle reservoirs is poorly constrained, and this study focuses on the investigation of fO(2) in ocean island basalts (OIBs). By analyzing trace elements in olivine of lavas from La Reunion island, it is found that the variable fO(2) in Reunion lavas is a result of assimilation processes within the volcanic edifice rather than source heterogeneity. It suggests that the Reunion mantle plume likely has fO(2) similar to that of mid-ocean ridge basalts (MORBs), despite isotopic evidence for the plume sampling an early-formed isolated mantle reservoir.

Summary: The March-April 2007 eruption of the Piton de la Fournaise volcano on La Reunion Island was the most significant in historical times. The eruption included fissure opening, major caldera collapse, lava emissions, steam fumaroles, and explosions, lasting until mid-April. The complex events involved magma withdrawal and replenishment at separate summit reservoirs.

Summary: Modeling of ionic diffusion in natural crystals has been developed to calculate timescales of geological processes, but improvements are needed to account for uncertainties in data sets. This study focused on Mg-Fe zonation in olivine crystals to examine fundamental aspects of timescale calculation uncertainty, highlighting the impact of geometric uncertainties and changing boundary conditions on diffusion modeling. Refinements in modeling methods, including incorporating temperature-dependent crystal growth rates and boundary conditions, resulted in significantly improved fits to the data set, providing more robust conclusions for future studies.

Summary: Cloud forests in Cordillera de Talamanca, Costa Rica, host a diverse array of tree epiphytes predominately composed of bryophytes and chlorolichens. These epiphytes play a significant role in nitrogen fixation, with bryophytes contributing the most nitrogen input to the ecosystem.

Summary: In Europe, the task of characterising, understanding and modelling natural forests is highly challenging due to centuries of forest management. National Forest Inventories offer a unique opportunity to investigate hidden natural forests, with 'latent reserves' showing more signs of naturalness than managed forests. However, more time may be required for these forests to fully detach from past management effects.
