Interspecific interactions in temperate agroforestry

Agroforestry Systems, 2004
The ecological principles that define the competitive and complementary interactions among trees, crops, and fauna in agroforestry systems have received considerable research attention during the recent past. These principles have not yet, however, been adequately integrated and synthesized into an operational approach.

Nuclear-cytoplasmic interactions in amoeba interspecific hybrids

Experimental Cell Research, 1974
Abstract Interspecific hybrids between two species of amoeba, A. proteus and A. indica have been produced by reciprocal nuclear transfer after enucleating the host cells. In the hybrid cells the diameter of the transplanted nucleus changes to that characteristic of the host cell nucleus. In the combination of A. indica nucleus and A.

VARIATION IN INTERSPECIFIC INTERACTIONS

Annual Review of Ecology and Systematics, 1988
Deux aspects sont etudies: la repartition des resultats,a l'interieur des populations,en fonction de la variation de l'âge et de la taille des individus,la densite,la taille et la structure des populations,ou la repartition des genotypes;et la variation des resultats en fonction de l'environnement.

Interspecific Interactions I: Predation and Parasitism

2020
Predation and parasitism are dominant forms of interspecific interactions in aquatic ecosystems. Predation effects have been more commonly quantified in aquatic ecosystems than disease. Diet studies documenting predation are substantially more common that routine monitoring for disease in aquaculture systems.

Interspecific Interactions Among Asian Honeybees

2010
The behavioural relationships of mixed-species colonies are reviewed and attempts made to uncover those features of their behaviour that are conserved subsequent to speciation. Both Apis cerana and Apis mellifera in mixed-colonies exhibited typical retinue behaviour towards heterospecific queens.

Interspecific Interactions II: Competition and Mutualism

2020
Competition and mutualism are important forms of biotic interaction in aquatic communities. Quantification of the population and community-level effects of these interactions has historically been less common in fisheries analyses than predation. In part, this reflects the difficulties in conducting controlled experiments for larger-bodied organisms in

Interspecific Interactions among Tropical and Subtropical Freshwater Fungi

Microbial Ecology, 1999
> Abstract Twenty-seven species of tropical and subtropical fungi isolated from freshwater were examined for evidence of interspecific interactions, which are important in determining the ecological roles of fungi. Evidence for interspecific interactions was examined by inoculating paired fungi 25 mm apart on the surface of agar plates.

Interspecific interactions in a methane‐utilizing mixed culture

Biotechnology and Bioengineering, 1980
AbstractA two‐member methane‐utilizing mixed culture of bacteria, formed by combining two pure cultures isolated from a naturally occurring methane‐utilizing mixed culture, was studied in continuous culture. From the nutritional requirements and substrate ranges of the pure cultures, a mechanism for the interspecific interactions occurring in the mixed
