Ecological dominants are always the most abundant members of a community?
Not necessarily. Ecological dominants can be the most influential species in a community due to their strong influence on the ecosystem, but they may not always be the most abundant in terms of sheer numbers. Their presence can significantly shape and define the community's structure and function.
What are species that play a critical role in maintaining the structure of an ecological community?
Keystone species are crucial in maintaining the structure of an ecological community. These species have a disproportionately large impact on their environment relative to their abundance. They help regulate the populations of other species, promote biodiversity, and contribute to the overall functioning of the ecosystem.
Which level of organization is often dominated by only a few species?
The community level of organization is often dominated by only a few species. These dominant species can have a significant impact on the structure and function of the community.
The idea that the destruction of one species in a community could greatly affect other members of the community has its roots in the hypothesis of community structure proposed by?
The idea that the destruction of one species in a community could greatly affect other members of the community has its roots in the hypothesis of community structure proposed by Charles Elton. Elton's work on food webs and trophic cascades helped to highlight the interconnectedness of species within ecosystems and the potential consequences of species loss on ecosystem stability.
What is numerical dominance within an ecological community?
Numerical dominance in an ecological community refers to the situation where a particular species has the highest population density or abundance among all the species present in that community. This species tends to outnumber and outcompete other species, influencing the structure and dynamics of the community. Numerical dominance can have significant impacts on the interactions and functioning of the ecosystem.

How do pathogens affect community structure?
Pathogens can disrupt community structure by causing disease outbreaks that can lead to declines in populations of certain species. This can create imbalances in the ecosystem, affecting the relationships between species and leading to shifts in community composition. Additionally, pathogens can impact the overall health and resilience of a community, making it more vulnerable to other stressors.
Explain how interspecific competition may affect community structure?
Interspecific competition occurs when different species compete for the same resources, such as food or territory, leading to resource depletion for one or both species. This can result in changes to species abundance and distribution within the community, potentially leading to shifts in the overall community structure as some species may outcompete others. Over time, interspecific competition can influence species diversity and the composition of communities.
What is community composition?
Community composition refers to the identity and relative abundance of species within a defined ecological community. It encompasses the variety of species present, their interactions with one another, and their distribution patterns within the community. Studying community composition helps scientists understand biodiversity and ecosystem dynamics.
Kangaroos are abundant in what country?
Kangaroos are abundant in many parts of Australia. This does not apply to all species, as many of the smaller species are endangered.
What is a species that provides structure to a community by creating locally stable conditions for other species?
A keystone species provides structure to a community by creating locally stable conditions for other species. For example, sea otters play a crucial role in kelp forest ecosystems by preying on sea urchins, which would otherwise overgraze kelp and destabilize the habitat. By maintaining kelp populations, sea otters support diverse marine life, demonstrating how one species can influence the broader ecological community.
