DNA barcoding works in practice but not in (neutral) theory. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: DNA barcode differences within animal species are usually much less than differences among species, making it generally straightforward to match unknowns to a reference library.

Genetic variability of Taenia saginata inferred from mitochondrial DNA sequences [PDF]

open access: yes, 2015
Taenia saginata is an important tapeworm, infecting humans in many parts of the world. The present study was undertaken to identify inter- and intraspecific variation of T.

Divergent drivers of leaf trait variation within species, among species, and among functional groups. [PDF]

open access: yes, 2018
Understanding variation in leaf functional traits-including rates of photosynthesis and respiration and concentrations of nitrogen and phosphorus-is a fundamental challenge in plant ecophysiology. When expressed per unit leaf area, these traits typically

Ecological Consequences of Intraspecific Variation in Coevolutionary Systems [PDF]

open access: yesThe American Naturalist, 2020
AbstractThe patterns and outcomes of coevolution are expected to depend on intraspecific trait variation. Various evolutionary factors can change this variation in time. As a result, modeling coevolutionary processes solely in terms of mean trait values may not be sufficient; one may need to study the dynamics of the whole trait distribution.

Natural epigenetic polymorphisms lead to intraspecific variation in Arabidopsis gene imprinting

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).

How self-regulation, the storage effect and their interaction contribute to coexistence in stochastic and seasonal environments [PDF]

open access: yes, 2019
Explaining coexistence in species-rich communities of primary producers remains a challenge for ecologists because of their likely competition for shared resources.

Intraspecific variation of recombination rate in maize [PDF]

open access: yesGenome Biology, 2013
Abstract Background In sexually reproducing organisms, meiotic crossovers ensure the proper segregation of chromosomes and contribute to genetic diversity by shuffling allelic combinations. Such genetic reassortment is exploited in breeding to combine favorable alleles, and in genetic research to identify

Intraspecific and interspecific functions in regulating vegetation biomass under nutrient addition in semiarid grasslands

open access: yesGlobal Ecology and Conservation
Long-term soil erosion causes widespread nitrogen (N) and phosphorus (P) limitation on the Loess Plateau. The response of community biomass to N and P addition is tightly linked to interspecific and intraspecific variations in community level traits.

Intraspecific variability in leaf traits strongly affects alder leaf decomposition in a stream [PDF]

open access: yes, 2008
This study assessed the intraspecific variability of senescent leaves of alder (Alnus glutinosa Gaertn.) and the effects of this variability on leaf decomposition in streams. Leaves were collected at five geographically distant locations in Europe.
