Feeding strategies and intraspecific competition in German yellowjacket (Vespula germanica). [PDF]

PLoS One, 2018
The German yellowjacket (Vespula germanica) is an opportunist predator and a scavenger, whose eclectic diet also includes honey, brood, dead and live honey-bees.

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

Ecology 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

Italian 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.

Intraspecific competition and coordination in the evolution of lateralization [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2008
Recent studies have revealed a variety of left–right asymmetries among vertebrates and invertebrates. In many species, left- and right-lateralized individuals coexist, but in unequal numbers (‘population-level’ lateralization). It has been argued that brain lateralization increases individual efficiency (e.g.

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

Animals, 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 ...

Robust coexistence in competitive ecological communities. [PDF]

Nat Commun
Darwin already recognized that competition is fiercest among conspecifics, a principle that later made intraspecific competition central to ecological theory through concepts such as niche differentiation and limiting similarity.

Responses of Maize (Zea mays L.) Roots to Nitrogen Heterogeneity and Intraspecific Competition: Evidence from a Pot Experiment Using the ‘Root Splitting’ Approach

Agronomy, 2022
A heterogeneous distribution of nutrients in the soil and the root interactions of crops coexist in agroecosystems. A ‘root splitting’ approach, i.e., splitting the root system into different nutrient compartments, was used to study nutrient ...

Intraspecific interference retards growth and development of cane toad tadpoles, but those effects disappear by the time of metamorphosis

Royal Society Open Science, 2023
Competition among larval anurans can occur via interference as well as via a reduction in per-capita food supply. Previous research on intraspecific interference competition in cane toad (Rhinella marina) tadpoles found conflicting results, with one ...

Inter- and Intraspecific Competition in Invasive Lactuca serriola and Co-Occurring Weedy Plant Species. [PDF]

Ecol Evol
While invasive success of alien plant species is often attributed to their superior competitive abilities, it is also suggested that competitive ability depends on the target species of competition and resource availability.
