A global invasion and divergence in plant-pathogen interactions

Ylva Lekberg, from MPG Ranch, discusses her article: Eco-evolutionary shifts in interactions between a globally invasive plant and belowground putative pathogens coincide with shifts in plant performance Some plant species become invasive in non-native ranges and outcompete native plants, reduce biodiversity, and alter ecosystem functions. Altogether, invasive species cost billions of dollars to manage. We…

Shifting plant investment strategies along climatic gradients drive ecosystem carbon cycling in alpine grasslands

Inge Althuizen, Norwegian Research Center AS (NORCE), discusses her article: Climate-induced shifts in plant investment strategies regulate ecosystem carbon cycling across alpine grasslands Alpine ecosystems provide a diversity of ecosystem services, including carbon storage. These cold ecosystems and carbon stored in them are particularly sensitive to climate change. But what are the mechanisms underlying carbon…

Climate warming doesn’t feel the same for everyone: The contrasted responses of tree saplings to global warming.

Benjamin Roux, University of Bordeaux in France, discusses his article: Tree canopy shapes the survival of oak and beech saplings during the regeneration stage along an elevation-driven temperature gradient The challenges of heatwaves for forest ecosystems As western Europe experiences yet another heatwave, most of the public discussion focuses on how human societies can adapt…

Beyond species interaction networks: The hidden role of individuals in community assembly

Liedson Carneiro, Southwestern Oklahoma State University, discusses his article: Structural differences in individual pollinator networks across bee species reveal the importance of population-level processes in the assembly of species interactions Plant–pollinator interactions are often described as networks; plant species are connected to pollinator species through their visits to flowers. This approach has advanced our understanding…

Life stage influences the performance of low and high elevation plants in a high elevation garden, but not as one might expect

Brandie Quarles-Chidyagwai, University of California, Davis, discusses her article: Adaptational lag at high elevations depends on life stage in a California wildflower With ongoing climate change, many plant species will have to track environmental changes through adaptation or poleward/upslope dispersal. High elevations in particular are experiencing warming temperatures, reduced snowpack, and shifting growing seasons. With…

Exploring the extremes of cation availability

Jonathan Ritson, who worked at the University of Manchester during this research, discusses his article: Cation responses to global changes alter ecological processes in ombrotrophic systems In bogs, we often focus on the hydrology of the system; there has also been a large body of work trying to understand the global implications of acid deposition…

Integrating multiple hypotheses to understand grassland drought resistance

Diana Bertuol Garcia, University of Victoria, discusses her article: Long-term aridity shapes grassland drought resistance and modulates the roles of plant diversity and functional composition As ecologists, we often ask how ecosystems cope with change. This question now feels more urgent than ever. Around the world, ecosystems are facing habitat loss, overexploitation, invasive species, rising…

When do you flower? It partly depends on your neighbors!

Kechang Niu and Pingyu Liu, Nanjing University, discuss their article: Earlier flowering, later fading: Plant diversity loss restructures alpine phenology via competitive release What is our paper about? For centuries, the timing of flowering has captivated both the public and scientists. Much of this fascination stems from a desire to understand the rhythms of life…

Above- and below-ground components do not respond equally to changing precipitation

Qingzhou Zhao, Umeå University in Sweden, discusses their article: Increasing precipitation reshapes alpine plant–microbial nutrient partitioning and enhances ecosystem carbon and nitrogen retention A rainy question in the alpine ecosystem Rainfall is changing as the climate warms. In many alpine regions, including the Tibetan Plateau, ecosystems are becoming not only warmer, but also wetter. At…

It is not just how many species are lost, but which ones disappear first

Shun Nonaka, Yokohama National University in Japan, discusses his article: Non-random species loss weakens functional diversity and species asynchrony, destabilizing grassland communities Why does the order of species loss matter? When we think about biodiversity loss, we often ask a simple question: how many species are disappearing? This is important, but it is not the…
