A new method to control the invasive sun corals (Tubastraea spp.): Underwater compressed‐air blasting

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater compressed‐air blasting is a novel method developed to control invasive sun corals (Tubastraea spp.). The technique removes coral soft tissue without fragmenting colonies, reducing the risk of regeneration and accidental spread. This approach offers a safer and practical tool for managing invasive corals in natural reefs and biofouling ...

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

Global Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Neuromuscular Regeneration: Perspective on the Application of Mesenchymal Stem Cells and Their Secretion Products

Stem Cells International, Volume 2016, Issue 1, 2016., 2016
Mesenchymal stem cells are posing as a promising character in the most recent therapeutic strategies and, since their discovery, extensive knowledge on their features and functions has been gained. In recent years, innovative sources have been disclosed in alternative to the bone marrow, conveying their associated ethical concerns and ease of harvest ...

Beyond Ecology: How Environmental and Social Landscapes Shape Tropical Forest Restoration in Southeast Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Restoration was more associated with environmental variables than socioeconomics. Active restoration was utilized in degraded areas and pasture abandonment favored natural regeneration. Successful tropical restoration is dependent on a complex interdependent mix of factors.

Effects of Human Mesenchymal Stem Cells Isolated from Wharton’s Jelly of the Umbilical Cord and Conditioned Media on Skeletal Muscle Regeneration Using a Myectomy Model

Stem Cells International, Volume 2014, Issue 1, 2014., 2014
Skeletal muscle has good regenerative capacity, but the extent of muscle injury and the developed fibrosis might prevent complete regeneration. The in vivo application of human mesenchymal stem cells (HMSCs) of the umbilical cord and the conditioned media (CM) where the HMSCs were cultured and expanded, associated with different vehicles to induce ...

Habitat Conditions and Neighborhood Interactions Drive the Phylogenetic Structure of Seedling Assemblages in a Tropical Forest Mosaic

Biotropica, Volume 57, Issue 6, November 2025.
In poor, well‐drained sandy soils, we observed the coexistence of more closely related species, suggesting that shared evolutionary history influences which seedlings survive under these restrictive conditions. Contrary to expectations, flooded areas harbored more distantly related species, likely because pathogens and other natural enemies limit the ...
