Local nutrient addition drives plant diversity losses but not biotic homogenization in global grasslands Open
Nutrient enrichment typically causes local plant diversity declines. A common but untested expectation is that nutrient enrichment also reduces variation in nutrient conditions among localities and selects for a smaller pool of species, ca…

Forb diversity globally is harmed by nutrient enrichment but can be rescued by large mammalian herbivory Open
Forbs (“wildflowers”) are important contributors to grassland biodiversity but are vulnerable to environmental changes. In a factorial experiment at 94 sites on 6 continents, we test the global generality of several broad predictions: (1) …

Forb diversity globally is harmed by nutrient enrichment but can be rescued by large mammalian herbivory Open
Forbs (“wildflowers”) are important contributors to grassland biodiversity and services, but they are vulnerable to environmental changes that affect their coexistence with grasses. In a factorial experiment at 94 sites on 6 continents, we…

Sustained mangrove reproduction despite major turnover in pollinator community composition at expanding range edge Open
Background and Aims How well plants reproduce near their geographic range edge can determine whether distributions will shift in response to changing climate. Reproduction at the range edge can be limiting if pollinator scarcity leads to p…

Compositional variation in grassland plant communities Open
Human activities are altering ecological communities around the globe. Understanding the implications of these changes requires that we consider the composition of those communities. However, composition can be summarized by many metrics w…

Environmental heterogeneity modulates the effect of plant diversity on the spatial variability of grassland biomass Open
Plant productivity varies due to environmental heterogeneity, and theory suggests that plant diversity can reduce this variation. While there is strong evidence of diversity effects on temporal variability of productivity, whether this mec…

Ecological network structure in response to community assembly processes over evolutionary time Open
The dynamic structure of ecological communities results from interactions among taxa that change with shifts in species composition in space and time. However, our ability to study the interplay of ecological and evolutionary processes on …

Forest ecosystem properties emerge from interactions of structure and disturbance Open
Forest structural diversity and its spatiotemporal variability are constrained by environmental and biological factors, including species pools, climate, land‐use history, and legacies of disturbance regimes. These factors influence forest…

Harnessing island–ocean connections to maximize marine benefits of island conservation Open
Islands support unique plants, animals, and human societies found nowhere else on the Earth. Local and global stressors threaten the persistence of island ecosystems, with invasive species being among the most damaging, yet solvable, stres…

Insectivorous birds reduce herbivory but do not increase mangrove growth across productivity zones Open
Top‐down effects of predators and bottom‐up effects of resources are important drivers of community structure and function in a wide array of ecosystems. Fertilization experiments impose variation in resource availability that can mediate …
View article: Nitrogen increases early‐stage and slows late‐stage decomposition across diverse grasslands
Nitrogen increases early‐stage and slows late‐stage decomposition across diverse grasslands Open
To evaluate how increased anthropogenic nutrient inputs alter carbon cycling in grasslands, we conducted a litter decomposition study across 20 temperate grasslands on three continents within the Nutrient Network, a globally distributed nu…
View article: Spatial turnover of multiple ecosystem functions is more associated with plant than soil microbial β‐diversity
Spatial turnover of multiple ecosystem functions is more associated with plant than soil microbial β‐diversity Open
Biodiversity—both above‐ and belowground—influences multiple functions in terrestrial ecosystems. Yet, it is unclear whether differences in above‐ and belowground species composition (β‐diversity) are associated with differences in multipl…

Successful management of invasive rats across a fragmented landscape Open
Summary Introduced mammalian predators are responsible for the decline and extinction of many native species, with rats (genus Rattus ) being among the most widespread and damaging invaders worldwide. In a naturally fragmented landscape, w…

Identification of novel bacterial biomarkers to detect bird scavenging by invasive rats Open
Rapid advances in genomic tools for use in ecological contexts and non‐model systems allow unprecedented insight into interactions that occur beyond direct observation. We developed an approach that couples microbial forensics with molecul…

Plant species’ origin predicts dominance and response to nutrient enrichment and herbivores in global grasslands Open
Exotic species dominate many communities; however the functional significance of species' biogeographic origin remains highly contentious. This debate is fuelled in part by the lack of globally replicated, systematic data assessing the rel…

Protective neighboring effect from ash trees treated with systemic insecticide against emerald ash borer Open
BACKGROUND The emerald ash borer (EAB) ( Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae) is now the most destructive invasive species in North America. While biocontrol using parasitoids shows promising results in natural forests,…
