Competitive Interactions Among Populus euphratica Seedlings Intensify Under Drought and Salt Stresses [PDF]

open access: yesPlants
Plant interactions and their responses to stress environments are important ecological processes for ecosystem stability and biodiversity formation, but how plant intraspecific relationships respond to environmental stresses remains to be studied in ...

Application of high resolution melting assay (HRM) to study temperature-dependent intraspecific competition in a pathogenic bacterium [PDF]

open access: yesScientific Reports, 2017
Studies on species’ responses to climate change have focused largely on the direct effect of abiotic factors and in particular temperature, neglecting the effects of biotic interactions in determining the outcome of climate change projections.

Ant Mortality with Food Competition in Forests along a Temperature Gradient

open access: yesInsects, 2022
The authors elucidated the relationship between temperature and mortality due to food competition in ant communities in forests. A field experiment was conducted using four bait types at six different oak forest sites with different mean annual ...

Spatial heterogeneity in light supply affects intraspecific competition of a stoloniferous clonal plant. [PDF]

open access: yesPLoS ONE, 2012
Spatial heterogeneity in light supply is common in nature. Many studies have examined the effects of heterogeneous light supply on growth, morphology, physiology and biomass allocation of clonal plants, but few have tested those effects on intraspecific ...

Interactive Effects of Intraspecific Competition and Drought on Stomatal Conductance and Hormone Concentrations in Different Tomato Genotypes

open access: yesHorticulturae, 2022
Plant physiological responses to various stresses are characterized by interaction and coupling, while the intrinsic mechanism remains unclear. The effects of intraspecific competition on plant growth, stomatal opening, and hormone concentrations were ...

Shift in competitive ability mediated by soil biota in an invasive plant

open access: yesEcology and Evolution, 2021
Understanding the shifts in competitive ability and its driving forces is key to predict the future of plant invasion. Changes in the competition environment and soil biota are two selective forces that impose remarkable influences on competitive ability.

The Intraspecific competition as a driver for true production potential of soybean

open access: yesItalian Journal of Agronomy, 2020
Phenotypic plasticity of agricultural plants is considered to be one of the main means by which plants cope with the variability of environmental factors.

Egg chemoattractants moderate intraspecific sperm competition [PDF]

open access: yesEvolution Letters, 2017
AbstractInteractions among eggs and sperm are often assumed to generate intraspecific variation in reproductive fitness, but the specific gamete-level mechanisms underlying competitive fertilization success remain elusive in most species. Sperm chemotaxis–the attraction of sperm by egg-derived chemicals—is a ubiquitous form of gamete signaling ...

Behavioural Indicators of Intra- and Inter-Specific Competition: Sheep Co-Grazing with Guanaco in the Patagonian Steppe

open access: yesAnimals, 2021
In extensive livestock production, high densities may inhibit regulation processes, maintaining high levels of intraspecific competition over time. During competition, individuals typically modify their behaviours, particularly feeding and bite rates ...

THE CONDITIONS FOR SPECIATION THROUGH INTRASPECIFIC COMPETITION [PDF]

open access: yesEvolution, 2006
It has been shown theoretically that sympatric speciation can occur if intraspecific competition is strong enough to induce disruptive selection. However, the plausibility of the involved processes is under debate, and many questions on the conditions for speciation remain unresolved.
