Allelopathy (ie, chemical interaction among species) was originally conceived as inclusive of
positive and negative effects of plants on other plants, and we adopt this view. Most studies …

Variation in natural selection across heterogeneous landscapes often produces (a) among‐
population differences in phenotypic traits,(b) trait‐by‐environment associations, and (c) …

Our understanding of the linkages between plant diversity and soil carbon and nutrient
cycling is primarily derived from studies at the species level, while the importance and …

Context of problem Crop cultivar mixtures can increase and stabilize productivity; however,
their effects on year-to-year temporal stability are positive in some cases, and neutral or …

Abstract Effects of plant diversity on grassland productivity, or overyielding, are found to be
robust to nutrient enrichment. However, the impact of cumulative nitrogen (N) addition (total …

Despite being visually cryptic, conspecific cultivar mixtures increase diversity and can
increase productivity in agricultural systems. However, the mechanisms underlying this …

Plant genetic diversity can affect ecosystem functioning by enhancing productivity, litter
decomposition and resistance to natural enemies. However, the mechanisms underlying …

Scientific communication relies on clear presentation of data. Logarithmic scales are used
frequently for data presentation in many scientific disciplines, including ecology, but the …

Leaf reflectance spectroscopy is emerging as an effective tool for assessing plant diversity
and function. However, the ability of leaf spectra to detect fine‐scale plant evolutionary …

Understanding how environmental factors shape patterns of genetic and phenotypic
variations in a species is necessary for conservation and plant breeding. However, these …
