Consumer‐resource theory predicts dynamic transitions between outcomes of interspecific interactions

Ecology Letters, 2009
Ecology 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.

Seasonal dynamics and interspecific competition in Oneida Lake Daphnia

Oecologia, 1998
I 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.

Linking ecomechanics and ecophysiology to interspecific interactions and community dynamics

Annals of the New York Academy of Sciences, 2013
To 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, 2007
Trait- 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.

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).

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;

Using phylogenetic data to investigate how interspecific interactions affect diversification dynamics

2023
The causes of the diversity differences that are apparent across taxonomic groups in the tree of life remain a key question in biology. This question has been investigated from the perspective of antagonistic, competitive, and mutualistic interactions.

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.

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.
