Organic Acid Accumulation and Associated Dynamic Changes in Enzyme Activity and Gene Expression during Fruit Development and Ripening of Common Loquat and Its Interspecific Hybrid

open access: yesFoods, 2023
Loquats have gained increasing attention from consumers and growers for their essential nutrients and unusual phenology, which could help plug a gap period at market in early spring. Fruit acid is a critical contributor to fruit quality.

Antibiotic intervention redisposes bacterial interspecific interacting dynamics in competitive environments

Environmental Microbiology, 2021
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, 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.

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.

The mechanisms of interspecific and intraspecific competition for resources and the dynamics model of community

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, 2019
AbstractStudies 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‐

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.

Co-dominance and succession in forest dynamics: The role of interspecific differences in crown transmissivity

Journal of Theoretical Biology, 2011
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.
