Intraspecific and intraindividual trait variability decrease with tree richness in a subtropical tree biodiversity experiment

Nature Communications
Phenotypic variability within tree species responds to local tree species richness. However, we lack evidence on how different sources of trait variation shape tree-tree interactions.

On the challenges of using field spectroscopy to measure the impact of soil type on leaf traits [PDF]

, 2017
Understanding the causes of variation in plant functional traits is a central issue in ecology, particularly in the context of global change.  Spectroscopy is increasingly used for rapid and non-destructive estimation of foliar traits, but few studies ...

Assessment of Genetic Variation in Apis nigrocincta (Hymenoptera: Apidae) in Sulawesi Revealed by Partial Mitochondrial Cytochrome Oxidase I Gene Sequences

Scientifica, 2020
Asian cavity-nesting honey bee Apis nigrocincta, a native bee species from Sulawesi and the Philippines, plays a vital role in pollinating flowering plants in local ecosystem and agriculture. In this study, we assessed the intraspecific genetic variation

Convocation

, 2014
The origins of phenotypic variation within mimetic Heliconius butterflies have long fascinated biologists and naturalists. However, the evolutionary processes that have generated this extraordinary diversity remain puzzling. Here we examine intraspecific

Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]

, 2008
Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

Cultivar diversity as a means of ecologically intensifying dry matter production in a perennial forage stand [PDF]

, 2014
The relationship between genotypic diversity and productivity has not been adequately explored in perennial forage production systems despite strong theoretical and empirical evidence supporting diversity\u27s role in ecosystem functioning in other ...

Intraspecific variability among Lannea species reveals promising morphotypes and ethnotypes in the semi-arid savannas of Burkina Faso (West Africa)

Journal of Agriculture and Food Research
Lannea species are among the fruit trees with high socio-economic importance in West Africa yet their intraspecific variability remains poorly studied, despite being essential for selection and domestication.

Illumina based whole mitochondrial genome of Junonia iphita reveals minor intraspecific variation

Genomics Data, 2015
In the present study, the near complete mitochondrial genome (mitogenome) of Junonia iphita (Lepidoptera: Nymphalidae: Nymphalinae) was determined to be 14,892 bp. The gene order and orientation are identical to those in other butterfly species.

Extending phylogenetic regression models for comparing within‐species patterns across the tree of life

Methods in Ecology and Evolution
Evolutionary biologists characterize macroevolutionary trends of phenotypic change across the tree of life using phylogenetic comparative methods. However, within‐species variation can complicate such investigations.

Climate and soil explain contrasting intraspecific trait variability of widespread species over a large environmental gradient

Global Ecology and Conservation
Both climatic and edaphic conditions are currently undergoing significant changes on a global scale. Early studies have suggested that climate and soil together shape plant performance.
