Looking up and down: How forest layers work together to keep ecosystems functioning

Jie Li, Beijing Forestry University in China, discusses their article: Cross-scale effects of multi-strata plant diversity on ecosystem multifunctionality in temperate forests What makes a forest thrive? While we often admire towering trees in a forest, what happens under their shade—the herbs, ferns, and small plants carpeting the forest floor—can be just as important. In…

Nectar sugar concentration matters in shaping bee-flower interactions

Chun-Feng Yang, Wuhan Botanical Garden of the Chinese Academy of Sciences, discusses their article: Nectar sugar concentration contributes to structuring bumble bee and plant interactions Why do flowers vary their nectar sugar concentrations? Producing nectar entails significant energetic costs for plants, with investment strongly correlated to sugar concentration. It is therefore believed that interspecific variation…

Shrub Expansion in the Arctic: Quantifying and Explaining the Transformation of Tundra Landscapes

Anna Derkacheva, Gerald “JJ” Frost, Howie Epstein, and Ksenia Ermokhina, of HSE University in Russia, Alaska Biological Research, Inc., the University of Virginia, and the Russian Academy of Sciences (respectively), discuss their article: Landscape patterns of shrubification in the Siberian low arctic: A machine learning perspective The Arctic tundra is experiencing some of the strongest…

Liana diversity and density in Ghana show positive association with precipitation, precisely opposite to pantropical trends

Bismark Ofosu-Bamfo, University of Energy and Natural Resources in Sunyani, Ghana, discusses his article: Patterns and drivers of liana community structure across five forest ecosystem types in Ghana In recent years, ecologists in the tropics have dedicated a good amount of research to understand the pattern and drivers of community assemblages of woody climbing plants,…

Seedlings in a hotter, drier, CO₂-rich world: How do they cope?

María Natalia Umaña and Inés Ibañez, University of Michigan, discuss their article: How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta-analysis Climate change is not happening one thing at a time. In forests across the globe, seedlings are already experiencing a mix of higher atmospheric CO₂, rising…

Soil Microbial Networks Under Long-term Nitrogen Stress: Reinforcing the Core of Ecosystem Health

Xiaobo Yuan and Yaodan Zhang, from Lanzhou University in China, discuss their article: Soil microbial networks mediate long-term effects of nitrogen fertilization on ecosystem multiservices Nitrogen (N) fertilization caused by anthropogenic activities such as fertilizer application and fossil fuel combustion have significantly impacted the capacity of ecosystems to support key services such as nutrient cycling…

How do hundreds of tree species occupy tropical forests? Large tree fall gaps might hold the answer

Damla Cinoğlu and Caroline Farrior, University of Texas at Austin, discuss their article: Small disturbances and subsequent competition for light can maintain a diversity of demographic strategies in a neotropical forest: Results from model-data integration Tropical forests are one of the most diverse ecosystems on Earth. They are fundamental for managing the global carbon budget and…

Foliar herbivory can reshape plant pollinator networks

Luiz Rezende and Martín Pareja, Universidade Estadual de Campinas (UNICAMP) in Brazil, discuss their article: Foliar herbivory pushes plant individuals towards the periphery of a plant-floral visitor interaction network Ecological interactions have fascinated naturalists for centuries. Watching bees and butterflies visit flowers continues to mesmerise and nurture a love of nature in children and adults…
