Toxins, 2023 Snake venoms are complex mixtures of toxins that differ on interspecific (between species) and intraspecific (within species) levels. Whether venom variation within a group of closely related species is explained by the presence, absence and/or relative ...

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

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

Ecosystem size predicts eco-morphological variability in a postglacial diversification [PDF]
, 2017 Identifying the processes by which new phenotypes and species emerge has been a long-standing effort in evolutionary biology. Young adaptive radiations provide a model to study patterns of morphological and ecological diversification in environmental ...

Ecological Consequences of Intraspecific Variation in Coevolutionary Systems [PDF]
The 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.

Molecular studies on intraspecific diversity and phylogenetic position of Coniothyrium minitans [PDF]
, 2001 Simple sequence repeat (SSR)±PCR amplification using a microsatellite primer (GACA)% and ribosomal RNA gene sequencing were used to examine the intraspecific diversity in the mycoparasite Coniothyrium minitans based on 48 strains, representing eight ...

Intraspecific variation of recombination rate in maize [PDF]
Genome 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

Global Ecology and ConservationLong-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.

The pine wood nematode, Bursaphelenchus xylophilus, in Portugal: possible introductions and spread routes of a serious biological invasion revealed by molecular methods [PDF]
, 2012 The pine wood nematode (PWN), Bursaphelenchus xylophilus, the causal agent of pine wilt disease (PWD), is a major world-wide pathogen and pest of pine, with impacts on forest health, natural ecosystem stability and international trade.
