Seasonal dynamics and age structure of drifting cyprinid fishes: an interspecific comparison

Ecology of Freshwater Fish, 2007
Abstract –  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;

Isozyme Polymorphism in Drosophila. IV. Interspecific Variation and Population Dynamics

1982
Drosophila 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).

Digest: Influence of abiotic and biotic factors on interspecific competition and diversification dynamics

Evolution
Abstract Only recently has there been renewed interest in how abiotic and biotic factors could influence the effect of interspecific competition. Graciotti et al. (2025) examined the role of interspecific competition and its effect on diversification dynamics in North American canids by developing models that include ecological, temporal,

Role of interspecific competition among predators and group size : A dynamical approach

Journal of Interdisciplinary Mathematics, 2023
Living in a group benefit all living beings for their survival and fulfilling needs. This paper proposes and analyzes a prey-predator system with the interspecific death and functional response Hassell-Varley. First, we discuss the existing stationary points of the system and their permanence.

Interspecific Variations in the Internal Mercury Isotope Dynamics of Antarctic Penguins: Implications for Biomonitoring

Environmental Science & Technology
Mercury (Hg) biomonitoring requires a precise understanding of the internal processes contributing to disparities between the Hg sources in the environment and the Hg measured in the biota. In this study, we investigated the use of Hg stable isotopes to trace Hg accumulation in Adélie and emperor penguin chicks from four breeding colonies in Antarctica.

Seasonal dynamics of interspecific trophic relations in a carabid beetle assemblage

1994
Interspecific trophic relations in an assemblage of carnivorous carabid beetles in mature spruce forests of Central Russia have been studied using a serological method.

Interactions of Intraspecific, Interspecific, and Apparent Competition with Host‐Pathogen Population Dynamics

Ecology, 1992
I investigated the interactions of intra— and interspecific competition with parasitism for populations of two terrestrial isopods, Porcellio scaber and Porcellio laevis, infected with a lethal virus. In field experiments, I varied densities of one or both isopod species in enclosures in which food and virus presence were also manipulated.

Spatially explicit dynamic N-mixture models with interspecific interactions

Interspecific interactions and movement are key factors that drive the coexistence of metapopulations in heterogenous landscapes. Yet, it is challenging to understand these factors because separating movement from local population processes relied on capture-based data that are difficult to collect.
