Strong intraspecific trait variation in a tropical dominant tree species along an elevational gradient

open access: yesPlant Diversity, 2020
Functional trait variation of plant species includes both inter- and intraspecific variation; however, trait-based plant ecology generally considers only interspecific variation while ignoring intraspecific variation.

Does intraspecific variation in juvenile Late Cretaceous ammonoids correlate with their systematic position, longevity and paleogeography? [PDF]

open access: yesSwiss J Palaeontol
Phenotypic intraspecific variation of organisms is essential for evolution and, thus, has the potential to provide crucial insights into evolutionary dynamics.

Natural epigenetic polymorphisms lead to intraspecific variation in Arabidopsis gene imprinting [PDF]

open access: yeseLife, 2014
Imprinted gene expression occurs during seed development in plants and is associated with differential DNA methylation of parental alleles, particularly at proximal transposable elements (TEs).

Spatial heterogeneity of soil factors enhances intraspecific variation in plant functional traits in a desert ecosystem. [PDF]

open access: yesFront Plant Sci
IntroductionFunctional traits of desert plants exhibit remarkable responsiveness, adaptability and plasticity to environmental heterogeneity.MethodsIn this study, we measured six crucial plant functional traits (leaf carbon, leaf nitrogen, leaf ...

Intraspecific Variation in Parental Care May Reflect Variation in Parental Quality. [PDF]

open access: yesEcol Evol
ABSTRACTThe existence of life‐history trade‐offs is a fundamental assumption of evolutionary biology and behavioural ecology, yet empirical studies have found mixed evidence for this. Such trade‐offs are expected when individuals vary in how they allocate their limited resource budgets between different life‐history functions (variation in resource ...

A role for gene duplication and natural variation of gene expression in the evolution of metabolism. [PDF]

open access: yesPLoS ONE, 2008
Most eukaryotic genomes have undergone whole genome duplications during their evolutionary history. Recent studies have shown that the function of these duplicated genes can diverge from the ancestral gene via neo- or sub-functionalization within single ...

Intraspecific morphometric variation in myxosporeans [PDF]

open access: yesFolia Parasitologica, 2016
Morphometric data from spores of ten myxosporean species were statistically analysed to explore myxosporean intraspecific variation in measurements when obtained from a sample from: (1) the same plasmodium, (2) different plasmodia from the same host and (3) different host individuals and localities.

The relative contribution of intraspecific variation and species turnover to the community-level foliar stoichiometric characteristics in different soil moisture and salinity habitats.

open access: yesPLoS ONE, 2021
BackgroundTrait-based approaches have been used to demonstrate the responses of plant functional traits to environmental change may manifest both among- and/or within-species.

Does habitat stability structure intraspecific genetic diversity? It’s complicated... [PDF]

open access: yes, 2020
Regional phylogeographic studies have long been conducted in the southeastern United States for a variety of species. With some exceptions, many of these studies focus on single species or single clades of organisms, and those considering multiple ...

Intraspecific nuclear DNA variation in Drosophila [PDF]

open access: yesMolecular Biology and Evolution, 1996
We have summarized and analyzed all available nuclear DNA sequence polymorphism studies for three species of Drosophila, D. melanogaster (24 loci), D. simulans (12 loci), and D. pseudoobscura (5 loci). Our major findings are: (1) The average nucleotide heterozygosity ranges from about 0.4% to 2% depending upon species and function of the region, i.e ...
