Apr 24, 2017 · The tundra is the coldest and driest ecological community in the world. The average temperature is -18 degrees Fahrenheit and it can drop to -94 degrees. During some months, the sun barely rises. The tundra winds can blow between 30 and 60 miles per hour. Caribou are a dominant species on the tundra. They can lower their metabolic rate and go ...
Mar 3, 2024 · Dominant species refers to the organism that has the greatest impact on an ecosystem and outcompetes other species in a specific environment. In ecology, it is the species that holds the highest abundance or biomass. Dominant species play a crucial role in shaping ecosystems by virtue of their large population size, high reproductive capacity ...

What is a dominant species?
In ecology, a dominant species refers to the group of organisms (or species) that have the most significant influence or control over the other organisms in its ecological community. A similar definition of it is in biology. Adominant species is a species that prevails in an ecosystem, especially when they are the most numerous and have a high ecological impact. This means they constitute the majority of the biomass. And because of high numerical advantage, dominant species tend to have an im...
What makes a species dominant?
Avolio et al. (2019) provided a summary of the characteristicsor traits that make a species potentially dominant. Several factors are at play (e.g, ecological, biological, genetics, spatial, evolutionary, etc.). Here is a summary of the types of dominance to explain the mechanism of ecological dominance. 1. Dominance by resource acquisition, three possible ways to explain this type of dominance: (1) based on the resource-ratio hypothesis, the species with the lowest equilibrium resource requi...
What’s the ecological role of dominant species?
Dominant species had an important role in the coexistence, distribution, and structuring of species. In ecology, species that are considered dominant have great population sizes as well as in productivity as compared to their competitors. In the ecological environment, the dominance of species depends on many factors like moisture, groundwater condition, and temperature. Ecological dominance impacts competition. Due to the availability of limited necessary resources for survival, competition...
Are humans a dominant species?Based on studies, of the earth’s total biomass, almost 80% is from plants. The findings of this study were published in Proceedings of the National Academy of Sciences USA. Humans occupy a small proportion of the total biomass. See the small pink dot as compared with the huge green dot denoting the plant biomass. The h...

Natural selection is a pressure that causes groups of organisms to change over time. Animals inherit their genetics from their parents or ancestors, and the environment is constantly changing. So, no organism is perfectly adapted to its environment. Thus, natural selection is constantly influencing the evolution of species.

- Lions vs. hyenas. Lions and hyenas are both large carnivorous predators that often compete for the same prey, such as zebras and wildebeest, in African savanna ecosystems.
- Trees vs. other trees. In a forest ecosystem, different species of trees compete for access to sunlight, water, and soil nutrients. Trees that are taller usually get first and longer-lasting access to sunlight, blotting out access to shorter trees.
- Humans vs. wildlife. This may seem like a broad example, but it is true! Humans compete for most resources available on the planet, including food and living space.
- Pollinators vs. pollinators. Insects such as bees and butterflies may compete for access to nectar and pollen on flowers. Insects that are able to access the nectar more efficiently, such as those with longer proboscises, may have an advantage over others.
A dominant species is a plant, animal or functional group of different species most commonly or conspicuously found in a particular ecosystem. It is generally the most populous species or comprises the greatest biomass in an ecosystem. It also influences the distribution of other organisms and helps define the ecosystem and its characteristics.
