Fauna Norvegica, 1985 An examination of 83 cyprinid specimens collected in Lake Akersvann, SE Norway in Sept. 1984 and in June and Sept. 1985 showed these to be natural hybrids between Scardinius erythrophthalmus and Abramis brama.

Identifying hybridizing taxa within the Daphnia longispina species complex: a comparison of genetic methods and phenotypic approaches [PDF]
, 2010 Daphnia galeata Sars, D. longispina O. F. Muller and D. cucullata Sars (Crustacea: Cladocera) are closely related species which often produce interspecific hybrids in natural populations.

Fauna Norvegica, 1987 A topographic description of the plerocercus larva of Floriceps saccatus is given. The larva was found to be covered by palmate or paw-like microtriches, not only on the adherent surface of the bothridia as earlier described from adult trypanorhynch ...

EFFECTS OF REFUGES AND DENSITY DEPENDENT DISPERSAL ON INTERSPECIFIC COMPETITION DYNAMICS
International Journal of Bifurcation and Chaos, 2012 We present a classical interspecific competition model. Individuals compete for a resource on a common patch and can go to a refuge. It is assumed that if species would remain on the competition patch, species 1 survives and species 2 would go extinct. Therefore, species 1 is Locally Superior Competitor (LSC) and species 2 Locally Inferior Competitor (

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]
, 2020 Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Fauna Norvegica, 1989 During the years 1980 - 1986, an intensive whitefish, Coregonus lavaretus, exploitation programme was carried out in the mountain reservoir Goppollen, SE Norway, in an attempt to improve whitefish quality and to reduce interspecific competition between ...

Agronomy, 2023 Weeds are a permanent constraint on crop productivity in agriculture. Due to the importance of the effect of weeds on the crop, there has been great interest in establishing the competitive ability of each species to optimize its control.

Fauna Norvegica, 1987 Carlin-tagged Atlantic salmon smolts have been released in the River Eira in western Norway during the period 1961 - 1980. Just after release birds were observed as smolt predators.

Conventional niche overlap measurements are not effective for assessing interspecific competition
Frontiers in Ecology and Evolution, 2023 Interspecific competition is notoriously difficult to detect and quantify, especially in species that are wide-ranging or otherwise difficult to track in the wild.

Epigenetic consequences of interploidal hybridisation in synthetic and natural interspecific potato hybrids [PDF]
, 2019 Interploidal hybridisation can generate changes in plant chromosome numbers, which might exert effects additional to the expected due to genome merger per se (i.e., genetic, epigenetic and phenotypic novelties).Wild potatoes are suitable to address this ...
