A global assessment of a large monocot family highlights the need for group-specific analyses of invasiveness

There are several emerging generalizations in invasion biology, but often the factors determining invasiveness are group-specific. Similarly to certain other plant families, Araceae species (arums or aroids) that have large native ranges and that have been widely introduced are more likely to become invasive. What is unique to the family is the great diversity of […]

Biomechanics and functional morphology of a climbing monocot

Climbing monocots can develop into large bodied plants despite being confined by primary growth. In a recent study published in AoB PLANTS, Hesse et al. measured surprisingly high stem biomechanical properties (in bending and torsion) in Flagellaria indica and showed that the lack of secondary growth is overcome by a combination of tissue maturation processes […]

Changes in composition, ecology and structure of high-mountain vegetation: a re-visitation study over 42 years

Mediterranean high-mountain ecosystems are increasingly threatened by climate change, causing biodiversity loss, habitat degradation and landscape modifications. In a new study published in AoB PLANTS, Evangelista et al. used phytosociological relevés to conduct a re-visitation study in order to analyze changes in floristic composition over the last 42 years in the central Apennines (Majella National Park). […]

High levels of genetic diversity and population structure in an endemic and rare species: Implications for conservation

The analysis of genetic structure and variability of isolated species is of critical importance in evaluating whether stochastic or human-caused factors are affecting rare species. Low genetic diversity compromises the ability of populations to evolve and reduces their chances of survival under environmental change. In a recent study published in AoB PLANTS, Turchetto et al. […]

Phylogeography of a widespread species: Pre-glacial vicariance, refugia, occasional blocking straits and long-distance migration

Phylogeographic studies give us the opportunity to reconstruct the historical migrations of species and link them with climatic and geographic variation. They are, therefore, a key tool to understanding the relationships among biology, geology and history. One of the most interesting biogeographical areas of the world is the Mediterranean region. However, in this area, the […]

Butterflies visit more frequently, but bees are better pollinators: the importance of mouthpart dimensions in effective pollen removal and deposition

Pollination studies often use visitation frequency of potential pollinators as an indicator of their importance, but this is only one component and may not reflect actual pollen-transfer rates. In a recent study published in AoB PLANTS, Barrios Roque et al. used new approaches to understand the pollination biology of the pineland golden trumpet, Angadenia berteroi, […]

Genetic delineation of local provenance defines seed collection zones along a climate gradient

Ecological restoration is often conducted with limited consideration of genetic diversity and the environmental factors that drive variation within species. In a new study published in AoB PLANTS, Hufford et al. examined the genetic diversity and environmental variation among 16 populations of Stylidium hispidum, an endemic southwestern Australian triggerplant. As a result they were able […]

Do plant traits predict the competitive abilities of closely related species?

Invasive species are a threat to every ecosystem and thus there is a strong incentive to predict which species will become invasive before they become too widespread and unmanageable. In a recent study published in AoB PLANTS, Schwartz et al. conducted a multi-year, temporally replicated, greenhouse and field experiment based on plant functional traits, quantifying competitive ability and making phylogenetic […]

Epigenetics of drought-induced trans-generational plasticity; consequences for range limit development

Offspring phenotypes may be altered by environments that their parents lived in.These environmentally-induced trans-generational effects may be mediated by epigenetic mechanisms such as DNA methylation. Little is known about the role of such epigenetic effects in evolution; however, it is expected to facilitate evolution. To expand geographic range, it is thought that most species would […]

Use of herbarium data to evaluate weediness in five congeners

A weed or not a weed? Many plant species grow somewhere on the continuum from undisturbed to very disturbed vegetation. Deciding on the degree of weediness is not an easy task, and is often based only on subjective observations. In a new study published in AoB PLANTS, Hanan-Alipi et al. compare data obtained during systematic […]
