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

Plant 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]

Swiss Journal of Palaeontology
Phenotypic intraspecific variation of organisms is essential for evolution and, thus, has the potential to provide crucial insights into evolutionary dynamics.

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

Frontiers in Plant Science
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 ...

The importance of intraspecific variation in litter consumption rate of aquatic and terrestrial macro-detritivores

Basic and Applied Ecology, 2022
Traits of organisms vary both at inter- and intraspecific levels. For macro-detritivores inhabiting lands and waters, there is only scattered information on the relative contribution of the intraspecific level for traits like litter consumption rates ...

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

PLoS 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 ...

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

PLoS 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.

Widespread variation in salt tolerance within freshwater zooplankton species reduces the predictability of community‐level salt tolerance

Limnology and Oceanography Letters, 2023
The salinization of freshwaters is a global threat to aquatic biodiversity. We quantified variation in chloride (Cl−) tolerance of 19 freshwater zooplankton species in four countries to answer three questions: (1) How much variation in Cl− tolerance is ...

Contrasting effects of plant inter- and intraspecific variation on community trait responses to nitrogen addition and drought in typical and meadow steppes

BMC Plant Biology, 2022
Background Inter- and intraspecific variation in plant traits play an important role in grassland community assembly under global change scenarios. However, explorations of how these variations contribute to the responses of community traits to nitrogen (

Intraspecific variation in the cochleae of harbour porpoises (Phocoena phocoena) and its implications for comparative studies across odontocetes [PDF]

PeerJ, 2020
In morphological traits, variation within species is generally considered to be lower than variation among species, although this assumption is rarely tested. This is particularly important in fields like palaeontology, where it is common to use a single

The good, the bad, and the ugly: the influence of skull reconstructions and intraspecific variability in studies of cranial morphometrics in theropods and Basal saurischians. [PDF]

PLoS ONE, 2013
Several studies investigating macroevolutionary skull shape variation in fossil reptiles were published recently, often using skull reconstructions taken from the scientific literature.
