Then the dynamical behaviors of the prey-predator relationship become more complex than before.
Coastal fish population dynamics are influenced by species-specific biological characteristics and inter-specific ecological processes, such as differences in spawning and feeding migrations, competence and use of resources, environmental fluctuations (e.g. sea water temperature and salinity), and prey-predator relationship, among others.
A prey-predator relationship between Helicoradomenia and non-cnidarian metazoan organisms, probably polychaetes, has been proposed earlier based on transmission electron microscopy data [ 38].
I collar and track moose as part of my wider research on prey-predator relationships.
Artificial lighting can damage sleep patterns, she said, and also "cause significant disruptions on ecosystems by changing communication between species, migrations, reproduction cycles or even the prey-predator relationships".
These isotopic discriminations provide a useful approach for estimating prey-predator relationships.
Ecology portrays these interactions as networks of species, called ecosystems, where dependencies between species generally capture prey-predator relationships.
Generally, the ecological models are used to study the competitive, cooperation, and prey-predator relationships between different species in nature [1 5].
Ecosystems are often partitioned into trophic levels which gather species with similar properties, such as the "resources" or the "top predators" in Fig. 3. Fig. 3 Illustrative ecosystem capturing the prey-predator relationships between a small set of species.
From the phytoplankton at the base of the food chain to the seals as the top predator, these organisms show a clear trend in stepwise 15N-enrichment, beautifully demonstrating the simple prey-predator relationships in this ecosystem.
