Sulfur‐Induced Lattice Modulation and Charge‐Transport Enhancement in MnO2 Nanowires for Hybrid Energy Storage

Energy Storage, Volume 8, Issue 1, February 2026.
ABSTRACT In this study, sulfur‐modified MnO2 nanowires (MnO2‐S) were synthesized via a two‐step hydrothermal and solid‐state process and evaluated as battery‐type electrodes for hybrid supercapacitors. Transmission electron microscopy (TEM) and high‐resolution TEM confirmed morphological integrity, while structural changes induced by sulfur inclusion ...

Simulating climate change scenarios established by the Intergovernmental Panel on Climate Change in aquatic mesocosms

Limnology and Oceanography: Methods, Volume 24, Issue 2, February 2026.
Abstract Climate change poses a major threat to ecosystems worldwide, with temperature changes being a key driver of ecological disruption in aquatic environments due to the limited ability of many aquatic species to relocate in response. Despite advances in aquatic experimental approaches to temperature control, most studies rely on simplified warming

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

The Role of Environmental Factors on Visual Communication in Neotropical Anurans

Global Ecology and Biogeography, Volume 35, Issue 2, February 2026.
ABSTRACT Aim Visual signals are a widespread behavioural attribute of communication among vertebrates, often employed during intrasexual competition or mate attraction, ultimately influencing reproductive success. However, the environmental factors driving visual signal evolution remain poorly understood.

How Management Practices Shape the “Local Habitat Signature” That Modulates Bird Communities in Urban Green Spaces

Biotropica, Volume 58, Issue 1, January 2026.
Local scale factors, not just the broad urban gradient, are the key drivers of urban bird communities. Our multi‐scale study found that specific management practices, such as managing leaf litter depth or the presence of unmanaged tall grass, explained the largest portion of variation in bird composition.
