How do past disturbances shape tree growth?

Yihong Zhu, University of California, Berkeley, discusses her article: Legacy effects under an emerging novel disturbance regime: A memory-based framework to quantify tree growth responses Emergent novel disturbance regime Moderate-severity disturbances, such as drought, pathogen irruptions, and prescribed fire, may not cause widespread tree mortality, but can leave lingering impacts on surviving trees. Such disturbances…

Can plant functional diversity dilute plant virus infection?

Beatriz Aguirre, Cornell University, discusses her article: Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production Greater plant diversity can protect plant communities from pathogens in wild and agricultural plant communities, and the effects of many aspects of diversity, such as genetic and species diversity,…

Testing the Island Rule in plants: A global study of leaf size evolution

Xoaquín Moreira, Misión Biológica de Galicia (CSIC, Spain), discusses his article: Global insular leaf size shifts follow the island rule, independently of insect herbivory and macroclimate This work came out of a collaboration between 17 institutions across five continents, all brought together by a shared interest in island biogeography. By combining data, expertise, and fieldwork…

Fast-growing and long-lived trees suffer most from their own kind

Nohemi Huanca-Nunez, Yale University, discusses her article: Integrated demographic strategies are more strongly associated with variation in conspecific density dependence than single traits in tropical tree seedlings, in both English and Spanish. A long-standing question in plant ecology is how so many tree species can coexist in tropical forests. A key part of the answer…

Thirteen years, three climates, one path to stability?

Johanne Gresse, University of Tübingen, discusses her article: Drought resistance drives population temporal stability of annuals in drylands Imagine a desert after rain. For a few brief weeks, the ground bursts into a colourful carpet of annual plants. At first glance, this display seems fleeting and fragile. But when observed over many years, a pattern…

Two grasses, two pathways: How plant strategies shape drought-microbe responses under global change

Gang Yang and Zuzana Münzbergová, Charles University in Prague, discuss their article: Contrasting drought responses in two grassland plant-microbe systems under climate change Drought is becoming more frequent and intense under global change, but plant responses vary widely. Some species are adapted to tolerate stress, while others perform well only when resources are abundant. Because…

Fast growing trees also decompose fast

Donghao Wu, from the Zhejiang University in China, discusses their article: The intrinsic coordination of tree growth strategy and wood decomposability What happens after a tree dies? As plant ecologists, we often focus on how trees grow: how fast they capture carbon, how tall they become, and how long they live. But forests are not…

How does climate change affect carbon uptake in montane meadows?

Rose Brinkoff and Olivia Vought, University of Michigan, discuss their article: The impact of warming on peak-season ecosystem carbon uptake is influenced by dominant species in warmer sites Ecosystems both absorb and release carbon. Carbon dioxide gas (CO2) in the atmosphere is taken up by plants through the process of photosynthesis and released by plants…

The plant that inspired pollination ecology

Markus Wagner, UK Centre for Ecology & Hydrology, Sandra Varga, University of Lincoln, and Richard Jefferson, former Natural England grassland specialist, discuss their article: Biological Flora of Britain and Ireland: Geranium sylvaticum Wood crane’s-bill as a model species for pollination ecology and plant breeding systems The structural adaptations of wood crane’s-bill (Geranium sylvaticum) to facilitate…

How to harmonise vegetation surveys

Marco Barandun, Agroscope and University of Zurich, discusses his article: Scaling species richness: When vegetation surveys don’t match in plot area What can you do when your dataset contains vegetation surveys with plots the size of a shoebox alongside plots the size of a living room? This was exactly the situation I found myself in…
