Competition and coexistence: The dangers of ignoring environmental heterogeneity

Annie Schiffer, Utah State University, discusses her article: The importance of accounting for spatial heterogeneity in studies of plant competition and coexistence Our paper explores how ignoring spatial environmental heterogeneity produces biases in competition and coexistence models. The original motivation for this study was to explain why interspecific competition was underestimated in observational studies of…

Local native species with global naturalization success can be strong competitors for alien species

Guan-Wen Wei and Mark van Kleunen, from the Ecology Lab at the University of Konstanz in Germany, discuss their article: Responses of naturalized alien plants to soil heterogeneity and competition vary with the global naturalization success of the native competitors Biological invasions are happening With the development of transportation and globalization, species have been introduced…

Tropical Forest Species Coexistence and Surprisingly Simple Models

Douglas Sheil, Forest Ecology and Forest Management Chair Group, Wageningen University and Research, The Netherlands, discusses his article: A simple competition model can predict rainforest tree diversity, species abundance and ecosystem functions Many tropical forests are remarkably diverse, often supporting hundreds of tree species in just a few hectares. But how can so many species…

Do Phylogenetic Relationships Influence Priority Effects in Grassland Plants?

Julia Dieskau, from Martin Luther University Halle-Wittenberg, discusses her article ‘Phylogenetic relationships and plant life stage but not biogeographic history mediate priority effects of European grassland plants’ Background What factors determine the composition of plant communities? Many scientists have been exploring this question from various perspectives throughout the past century. Despite their efforts, there are…

Succession: a key to understanding biodiversity loss and restoration

Lucy Ridding discusses the background, work and findings on her recent research for Do plant traits influence primary succession patterns for bryophytes and vascular plants? Evidence from a 33-year chronosequence on bare chalk with fellow ecologists Peter Hawes, Robin Walls, Sharon L. Pilkington, Richard F. Pywell and Oliver L. Pescott. Background We’ve been researching succession…

Soil fertility drives plant life down-under

Rachel Standish discusses her recent article: Mycorrhizal symbiosis and phosphorus supply determine interactions among plants with contrasting nutrient-acquisition strategies. Find out more about the importance of below-ground mechanisms for understanding factors determining community structure. The south-west region of Western Australia is a drawcard for plant nerds. Geographic isolation, a stable climate, and ‘quiet’ flat landscape…

Editor’s Choice: Volume 109 Issue 2

The Editor’s Choice for our February issue is “Spatial mapping of root systems reveals diverse strategies of soil exploration and resource contest in grassland plants“ by Lepik et al. This article combines fine‐scale measurements of plant root distributions with spatial statistics, yielding new insights into plant behavioural strategies. Here the handling Editor, JC Cahill, provides an overview…

Model fitting in ecology: trade-offs between complexity and generality

Journal of Ecology recently published new research article by Clark et al. Predicting species abundances in a grassland biodiversity experiment: Trade‐offs between model complexity and generality Author Adam Clark discusses the paper in more detail and explores the trade‐off between bias and variance when modelling ecological systems. It is common knowledge that increasing the number of…
