Weed management in grain legumes using an intercropping approach [PDF]

open access: yes, 2004
Grain legumes benefit the farming system via symbiotic N2 fixation and subsequent residue incorporation contributing to soil fertility together with their effect as break-crop in cereal rich rotations.

Clash of the Invaders: Competition Dynamics of Bromus tectorum and Ventenata dubia in an Addition Series Study

open access: yesEcology and Evolution
Competitive interactions between co‐occurring invasive species can have detrimental impacts on native communities and cause counter‐effective responses to management.

A unified mechanistic model of niche, neutrality and violation of the competitive exclusion principle [PDF]

open access: yes, 2012
The origin of species richness is one of the most widely discussed questions in ecology. The absence of unified mechanistic model of competition makes difficult our deep understanding of this subject.

Williamson's Theory of Interspecific Competition [PDF]

open access: yesNature, 1958
I AM glad that Drs. Andrewartha and Browning have been able to go some way with me. I hope that the following remarks will help them to travel further. The example of the car was used as an analogy, not as an argument. Any population that persists for more than a few generations must be controlled: any car that progresses more than a few yards without ...

Complex Behavior in Simple Models of Biological Coevolution

open access: yes, 2006
We explore the complex dynamical behavior of simple predator-prey models of biological coevolution that account for interspecific and intraspecific competition for resources, as well as adaptive foraging behavior.

Competition for food resources affects time-of-deathestimation variables in the forensic-relevant fly species Lucilia sericata and Calliphora vicina

open access: yesUniversitas Scientiarum
In forensic entomology, larval density and competition for food resources among the first cadaver-colonizing insects can affect the accuracy and reliability of the estimated time of death as the minimal postmortem interval (mPMI).

Competitive ability of grain legume-barley intercrops towards volunteer crops and weeds [PDF]

open access: yes, 2006
Field pea (Pisum sativum L.) and blue lupin (Lupinus angustifolius L.) were either sole cropped or inter-cropped with barley (Hordeum vulgare L.) at two levels of nitrogen application to determine the effects of interspecific interaction in an intercrop ...

Estimating the tolerance of species to the effects of global environmental change

open access: yes, 2013
Global environmental change is affecting species distribution and their interactions with other species. In particular, the main drivers of environmental change strongly affect the strength of interspecific interactions with considerable consequences to ...

Spatial Overlap and Behavioral Interactions Among Four Habronattus Jumping Spider Species in a Mixed‐Species Assemblage

open access: yesEcology and Evolution
Within mixed‐species assemblages, closely related species may face interspecific competition and reproductive interference. Species may evolve adaptations to outcompete or coexist, though most assemblages likely exist in a nonequilibrium state between ...
