Consumer‐resource theory predicts dynamic transitions between outcomes of interspecific interactions
Ecology Letters, 2009Ecology Letters(2009) 12: 1357–1366AbstractInteractions between two populations are often defined by their interaction outcomes; that is, the positive, neutral, or negative effects of species on one another. Yet, signs of outcomes are not absolute, but vary with the biotic and abiotic contexts of interactions.

Summary Interspecific interaction happens frequently among bacterial species and can promote the colonization of polymicrobial community in various environments. However, it is not clear whether the intervention of antibiotics, which is a common therapeutic method for infectious disease, will influence the ...

Linking ecomechanics and ecophysiology to interspecific interactions and community dynamics
Annals of the New York Academy of Sciences, 2013To predict community‐level responses to climate change, we must understand how variation in environmental conditions drives changes in an organism's ability to acquire resources and translate those resources into growth, reproduction, and survival. This challenge can be approached mechanistically by establishing linkages from biophysics to community ...

DEFINING AND MEASURING THE IMPACT OF DYNAMIC TRAITS ON INTERSPECIFIC INTERACTIONS
Ecology, 2007Trait- and density-mediated indirect effects describe different pathways by which indirect interactions in food webs are propagated from one species to another, through changes in intermediate species. A series of articles in Ecology has progressively altered the original definitions of "trait-mediated" to the point where understanding is being impeded.

Seasonal dynamics and interspecific competition in Oneida Lake Daphnia
Oecologia, 1998I investigated the population dynamics and competitive interactions of two species of the suspension-feeding crustacean Daphnia in Oneida Lake, N.Y. Both species have persisted in the lake for decades, but their water-column densities are negatively correlated. The larger Daphnia pulicaria dominates in some years, the smaller D.

Ecological Modelling, 1993
Abstract In this paper, the absorption of resources and the physiological consumption are considered as two elements of a species' competitive ability, and plant species' maintenance of the balance between absorption of resources and physiological consumption is a measurement of the species' competitive ability. New models on the basis of the Riccati

Long‐term dynamics of Alpine ungulates suggest interspecific competition
Journal of Zoology, 2019AbstractStudies identifying interspecific competition require the investigation of negative long‐term effects between sympatric species showing overlap in resource use. A potential for competition exists between red deer Cervus elaphus and chamois Rupicapra spp., as revealed by the high dietary overlap observed throughout the range where the species co‐

Forests that are composed of two or more tree species with similar ecological strategies appear to contradict the competitive exclusion principle. Beech-maple communities are a well-known example of such a system. On a local scale, a number of mechanisms have been proposed to explain the coexistence of these two species.

Isozyme Polymorphism in Drosophila. IV. Interspecific Variation and Population Dynamics
1982Drosophila melanogaster is one of the cosmopolitan species in the genus Drosophila. In many localities it is also the most common Drosophila species. However, in recent years some reports have indicated that its sibling, D. simulans has become the dominant species in many localities (Tantawy et al., 1970; Mourad et al., 1974).

Seasonal dynamics and age structure of drifting cyprinid fishes: an interspecific comparison
Ecology of Freshwater Fish, 2007Abstract – We investigated interspecific differences in the downstream drift of seven species of young‐of‐the‐year cyprinids over a 2‐year period in two central European rivers, using a comparison of drifting fish with fish collected from nurseries at the same time and the same site as the drift samples. Species varied in the utilisation of the drift;
