Intraspecific Variation Patterns of the Caudal Complex in Extant and Fossil Teleosts, with Comments on Implications into Taxonomy and Systematics: a Case Study. [PDF]

open access: yesAnuário do Instituto de Geociências, 2007
Comparative morphology remains as afundamental support of the interrelationshiphypotheses of living and fossil fish taxa. Theconceptualization of the characters is only possibleafter the comparative analysis that shows themorphological variation of ...

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

open access: yesBasic 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 ...

Predictable Patterns Of Disruptive Selection In Stickleback In Postglacial Lakes [PDF]

open access: yes, 2008
Disruptive selection is often assumed to be relatively rare, because it is dynamically unstable and hence should be transient. However, frequency-dependent interactions such as intraspecific competition may stabilize fitness minima and make disruptive ...

Temperature and intraspecific variation affect host–parasite interactions

open access: yesOecologia, 2023
AbstractParasites play key roles in regulating aquatic ecosystems, yet the impact of climate warming on their ecology and disease transmission remains poorly understood. Isolating the effect of warming is challenging as transmission involves multiple interacting species and potential intraspecific variation in temperature responses of one or more of ...

Assessing Intraspecific Variation of Tree Species Based on Sentinel-2 Vegetation Indices Across Space and Time

open access: yesRemote Sensing
Forest ecosystems are vital for biodiversity, climate regulation, and ecosystem services. Their resilience depends not only on species diversity but also on intraspecific variation—the genetic and phenotypic differences within species—which underpins ...

A trans-Amazonian screening of mtDNA reveals deep intraspecific divergence in forest birds and suggests a vast underestimation of species diversity. [PDF]

open access: yesPLoS ONE, 2012
The Amazonian avifauna remains severely understudied relative to that of the temperate zone, and its species richness is thought to be underestimated by current taxonomy.

Intraspecific Variation on Early Growth of Neolamarckia Cadamba Miq. in Provenance-progeny Tests in West Java Province, Indonesia [PDF]

open access: yes, 2016
Genetic parameters on early growth of Neolamarckia cadamba, an indigenous species with potential as a source of wood timber, were estimated in open-pollinated provenance-progeny tests at two sites in West Java Province, Indonesia.

The Origin, Succession, and Predicted Metabolism of Bacterial Communities Associated with Leaf Decomposition. [PDF]

open access: yes, 2019
Intraspecific variation in plant nutrient and defensive traits can regulate ecosystem-level processes, such as decomposition and transformation of plant carbon and nutrients.

Intraspecific floral colour variation in three Pedicularis species

open access: yesPlant Diversity
Flower constancy describes the phenomenon that pollinators tend to successively visit flowers of a single species during foraging, reducing reproductive interference in natural communities.

The Effects of Intraspecific Variation of Crayfish Behavior on Nutrient Cycling in Aquatic Environments [PDF]

open access: yes, 2020
Human activities are rapidly altering species traits at a global scale. Yet, there remains a critical need to determine whether trait variation within species affects ecosystem responses to global change. In particular, intraspecific variation in feeding
