Exploring local immunological adaptation of two stickleback ecotypes by experimental infection and transcriptome-wide digital gene expression analysis [PDF]

open access: yes, 2012
Understanding the extent of local adaptation in natural populations and the mechanisms that allow individuals to adapt to their native environment is a major avenue in molecular ecology research. Evidence for the frequent occurrence of diverging ecotypes

Effect of Drought on Herbivore-Induced Plant Gene Expression: Population Comparison for Range Limit Inferences

open access: yesPlants, 2016
Low elevation “trailing edge” range margin populations typically face increases in both abiotic and biotic stressors that may contribute to range limit development.

De novo sequencing of the Hypericum perforatum L. flower transcriptome to identify potential genes that are related to plant reproduction sensu lato [PDF]

open access: yes, 2015
Background: St. John's wort (Hypericum perforatum L.) is a medicinal plant that produces important metabolites with antidepressant and anticancer activities.

Ancient polymorphisms contribute to genome-wide variation by long-term balancing selection and divergent sorting in Boechera stricta

open access: yesGenome Biology, 2019
Background Genomic variation is widespread, and both neutral and selective processes can generate similar patterns in the genome. These processes are not mutually exclusive, so it is difficult to infer the evolutionary mechanisms that govern population ...

Moth oviposition shapes the species-specific transcriptional and phytohormonal response of Nicotiana attenuata to larval feeding [PDF]

open access: yes, 2018
Oviposition by lepidopteran herbivores on Nicotiana attenuata primes plant defence responses that are induced by the feeding larvae. While oviposition by both the generalist Spodoptera exigua and the specialist Manduca sexta primes the production of ...

Genetske promjene uvjetovane onečišćenjem [PDF]

open access: yes, 2009
Sa pojačanim onečišćenjem okoliša koji uzrokuje čovjek, razni organizmi se moraju nositi na razne načine. Samo onečišćenje može imati direktan ili indirektan utjecaj.

De novo sequencing and characterization of floral transcriptome in two species of buckwheat (Fagopyrum) [PDF]

open access: yes, 2011
Background Transcriptome sequencing data has become an integral component of modern genetics, genomics and evolutionary biology. However, despite advances in the technologies of DNA sequencing, such data are lacking for many groups of living organisms ...

Testing a General Theory for Optimal Flowering Time in Deciduous Perennial Plants as a Function of Growing Season Length

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
Climate change affects both the start and duration of growing seasons, creating complex effects on optimal flowering timing that go beyond simple responses to earlier springs. Using optimal energy allocation theory, we found a nonlinear relationship between growing season length and optimal flowering time which was supported by two experiments with ...

Insights into the role of differential gene expression on the ecological adaptation of the snail Littorina saxatilis [PDF]

open access: yes, 2010
Background In the past 40 years, there has been increasing acceptance that variation in levels of gene expression represents a major source of evolutionary novelty.

Temperature and the evolution of flower color: A review

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.
