Phenotypic plasticity in response to the social environment: effects of density and sex ratio on mating behaviour following ecotype divergence. [PDF]

open access: yesPLoS ONE, 2010
The ability to express phenotypically plastic responses to environmental cues might be adaptive in changing environments. We studied phenotypic plasticity in mating behaviour as a response to population density and adult sex ratio in a freshwater isopod (

Effects of Toxic Concentrations of Cadmium, Lead, or Zinc on Leaf Morphology, Anatomy and Calcium Oxalate Content in Metallicolous and Non-Metallicolous Ecotypes of Dianthus carthusianorum L. [PDF]

open access: yesPlants
Tolerance to metals develops independently across plant species and even among populations of the same species under strong environmental pressure. This study compares the morphology and leaf anatomy of Dianthus carthusianorum L. originating from a Zn–Pb

Ecotypic Identity and Manipulated Rainfall Modulate Diversity‐Productivity Relationships Across a Precipitation Gradient [PDF]

open access: yesEcology and Evolution
Understanding the context‐dependent nature of diversity‐productivity relationships is essential for predicting community responses to environmental change and informing restoration strategies.

Genetic relationship and pedigree of Chinese watermelon varieties based on diversity of perfect SNPs

open access: yesHorticultural Plant Journal, 2022
Watermelon (Citrullus lanatus) is one of the world's most important fruit crops, and China produces the most watermelons in the world. Recently, a watermelon variome consisting of 414 key resequenced accessions was reported.

THE ECOTYPE CONCEPT [PDF]

open access: yesNew Phytologist, 1946
The ecotype concept (Turesson, 1922) is a population concept, and by definition an ecotype is an intraspecific product of environmental selection arising as a result of genotypic response to a particular habitat. Accordingly, before a population qualifies for ecotype status, a relationship must be demonstrated between its heredity and the prevailing ...

Phytotoxic Potential and Phenolic Profile of Extracts from Scrophularia striata

open access: yesPlants, 2021
A large number of plants produce secondary metabolites known as allelochemicals that are capable of inhibiting the germination of competitive species.

Highly replicated evolution of parapatric ecotypes [PDF]

open access: yesMolecular Biology and Evolution, 2020
Abstract Parallel evolution of ecotypes occurs when selection independently drives the evolution of similar traits across similar environments. The multiple origin of ecotypes is often inferred on the basis of a phylogeny which clusters populations according to geographic location and not by the environment they ...

Plasticity plays a dominant role in regulating the phenological variations of sugar maple populations in Canada

open access: yesFrontiers in Ecology and Evolution, 2023
Global changes affect the growing conditions of terrestrial ecosystems, causing a mismatch between plant phenology and local climates in Northern regions.

Genetic Variation and Preliminary Indications of Divergent Niche Adaptation in Cryptic Clade II of Escherichia

open access: yesMicroorganisms, 2020
The evolution, habitat, and lifestyle of the cryptic clade II of Escherichia, which were first recovered at low frequency from non-human hosts and later from external environments, were poorly understood.
