Scale‐dependent variation in leaf functional traits clarifies mechanisms of invasion Open
Comparing the functional traits of co‐occurring native and invasive plant species can offer insight regarding mechanisms of invasion. Previous studies have failed to reach a consensus, indicating that the extent of trait differences betwee…

Plant litter trait variation between native and nonnative species across steep climate gradient in Hawaiian Islands Open
Oceanic islands have high biodiversity due to high rates of endemicity, which is now severely threatened by global change, including biological invasions. Invasive plants are predicted to displace native plants via vigorous resource use as…

Using long‐term tree diversity experiments to explore the mechanisms of temporal shifts in forest ecosystem functioning Open
Plant diversity is known to influence ecosystem functioning, but the strength and direction of this relationship vary considerably among studies, most of which have a short duration. In communities with long‐lived species, such as forests,…

The ontogenetic dimension of plant functional ecology Open
Plant functional strategies change considerably as plants develop, driven by intraindividual variability in anatomical, morphological, physiological and architectural traits. Developmental trait variation arises through the complex interpl…

A test of island plant syndromes using resource‐use traits Open
Despite representing a fraction of the global terrestrial surface area, oceanic islands are disproportionately diverse in species, resulting from high rates of endemicity. Island plants are thought to share a unique phenotype—referred to a…

Variability in seed salinity tolerance in an island coastal community Open
Background and Aims Islands, with their long coastlines and increased vulnerability to sea level rise, offer compelling opportunities to investigate the salinity tolerance of coastal plants. Seeds are generally more vulnerable than other p…

Hawai‘i forest review: Synthesizing the ecology, evolution, and conservation of a model system Open
As the most remote archipelago in the world, the Hawaiian Islands are home to a highly endemic and disharmonic biota that has fascinated biologists for centuries. Forests are the dominant terrestrial biome in Hawai'i, spanning complex, het…

Intraspecific trait variation in plants: a renewed focus on its role in ecological processes Open
Background Investigating the causes and consequences of intraspecific trait variation (ITV) in plants is not novel, as it has long been recognized that such variation shapes biotic and abiotic interactions. While evolutionary and populatio…

Additive and non‐additive responses of seedlings to simulated herbivory and drought Open
Drought is a global threat, increasing in severity and frequency throughout tropical ecosystems. Although plants often face drought in conjunction with biotic stressors, such as herbivory or disease, experimental studies infrequently test …
View article: Intraspecific trait variation and reversals of trait strategies across key climate gradients in native Hawaiian plants and non-native invaders
Intraspecific trait variation and reversals of trait strategies across key climate gradients in native Hawaiian plants and non-native invaders Open
Background and Aims Displacement of native plant species by non-native invaders may result from differences in their carbon economy, yet little is known regarding how variation in leaf traits influences native–invader dynamics across clima…

Structural defence is coupled with the leaf economic spectrum across saplings of spiny species Open
Given that the rate of resource capture constrains plant growth and defence, understanding the linkage between the leaf economic spectrum (LES) and defence and how it contributes to growth is central to predicting species performance. In s…

Local adaptation constrains drought tolerance in a tropical foundation tree Open
Plant species with broad climatic ranges might be more vulnerable to climate change than previously appreciated due to intraspecific variation in climatic stress tolerance. In tropical forests, drought is increasingly frequent and severe, …
View article: Developmental constraints and resource environment shape early emergence and investment in spines in saplings
Developmental constraints and resource environment shape early emergence and investment in spines in saplings Open
Background and Aims Herbivory by large mammals imposes a critical recruitment bottleneck on plants in many systems. Spines defend plants against large herbivores, and how early they emerge in saplings may be one of the strongest predictors…
View article: Shifts in woody plant defence syndromes during leaf development
Shifts in woody plant defence syndromes during leaf development Open
Herbivores target young leaves in forests world‐wide. How this strong and predictable selection pressure has shaped plant defence syndromes remains unclear. Specifically, whether young leaf herbivory has led to general global patterns of s…

Dissecting macroecological and macroevolutionary patterns of forest biodiversity across the Hawaiian archipelago Open
Biodiversity patterns emerge as a consequence of evolutionary and ecological processes. Their relative importance is frequently tested on model ecosystems such as oceanic islands that vary in both. However, the coarse-scale data typically …

Ontogenetic variation in salinity tolerance and ecophysiology of coastal dune plants Open
Background and Aims Global climate change includes shifts in temperature and precipitation, increases in the frequency and intensity of extreme weather events and sea level rise, which will drastically impact coastal ecosystems. The aim of…

OpenNahele: the open Hawaiian forest plot database Open
This data paper provides a description of OpenNahele, the open Hawaiian forest plot database. OpenNahele includes 530 forest plots across the Hawaiian archipelago containing 43,590 individuals of 185 native and alien tree, shrub and tree f…

Intraspecific and interspecific variation in prickly poppy resistance to non-native generalist caterpillars Open
Background: Prickly poppies (genus Argemone , Papaveraceae) epitomize well-defended plants. With high prickle densities and exudation of bright yellow latex from glaucous leaves, there are few reports of herbivore damage on these plants. Y…

Low tolerance to simulated herbivory in Hawaiian seedlings despite induced changes in photosynthesis and biomass allocation Open
Native Hawaiian plants expressed low tolerance to a conservative level of simulated herbivory. Root growth decreased in response to damage, but this was not associated with greater tolerance, suggesting this response may be due to allocati…

Tougher and thornier: general patterns in the induction of physical defence traits Open
Summary Most plants rely at least in part on physical defence traits to deter herbivores, and yet, very little is known about the inducibility of these traits. A meta‐analysis was conducted on data extracted from 57 publications from 1982 …
