Experimental resource supplementation shifts ant-mediated defense on silver cholla

Jenna Braun, York University, Toronto, discusses her article: Experimental resource supplementation shifts ant-mediated defense on silver cholla Extra-floral nectaries (EFN) play an important role within mutualisms between plants and ants. In this relationship, ants receive a nutrient-rich food source from plants in exchange for defending the plant from herbivores. Ant species are not equally effective…

Extrafloral nectary tree-driven soil carbon sequestration

Yumei Pan, Xiaojuan Liu, Michael Staab, and Naili Zhang, Beijing Forestry University in China, discuss their article: Soil carbon sequestration: Facilitated effect of extrafloral nectary trees in a diverse subtropical forest Carbon: Crucial role in climate change mitigation Soil organic matter dynamics and carbon sequestration are critical for mitigating climate change. Forest soils, which account…

Cover stories: Volume 109 Issue 2

The cover image for our new issue shows an ant standing on the tip of a Lafoensia pacari leaf in the Cerrado, Brazil. Author Kleber Del-Claro shares the story behind this stunning image, which was taken by co-author Denise Lange and relates to their recent research article “Climate seasonality drives ant–plant–herbivore interactions via plant phenology in an extrafloral…

Climate driven seasonal patterns in an ant–plant–herbivore interaction

How do seasonal changes in climate influence ecological interactions in an extrafloral nectary‐bearing plant community? Find out in recently published Journal of Ecology paper by Calixto et al. Author Kleber Del-Claro explains how climate can directly and indirectly impact ant–plant–herbivore interactions, and how we can better understand these changes by considering plant phenology over time.…

Optimal Defense Theory in an ant–plant mutualism

Here we take a closer look at a fascinating plant defense article by Calixto et al., which has recently been published in Journal of Ecology. Author Kleber Del-Claro explains different methods for anti-herbivore plant defenses and shares the results of this research, which is the first to show that ant recruitment via extrafloral nectar follows…
