Niche conservatism theory suggests that recently diverged sister species share the same ecological niche. However, if the ecological niche evolves as part of the speciation process, the ecological pattern could be useful for recognizing cryptic species. In a broad sense systematists agree that the ni...
Background: Although pelagic seabirds are broadly recognised as indicators of the health of marine systems, numerous gaps exist in knowledge of their at-sea distributions at the species level. These gaps have profound negative impacts on the robustness of marine conservation policies. Correlative ...
Niche differentiation is a key stabilizing mechanism in the maintenance of biodiversity and species coexistence. Recent work shows that trophic niche partitioning between parrotfishes (Labridae: Scarini) is more extensive than previously described. One Indo-Pacific species,Scarus spinus, appears highly sp...
Answer to: why exotic species represent a threat to native species. Give an example of an exotic species threatening the survival of one or more...
Innovations allow the introduction of products and technologies not yet available on the market, so they guarantee the company’s profitability Innovations facilitate the creation of a product, technological, or market niche for a company Leadership position even in a narrow area ensures competitive inc...
Nature fixes the problem of allowing many species to apparently use the same resource because each species uses a different part of the resource. In other words, nature creates opportunities for competitive exclusion. The definition of the competitive exclusion principle says that the niche of a ...
Using abiotic and biotic examples, give real examples of how studying ecology can explain the extinction of a species. Use at least two different organisms in your examples of species that are extinct. What are biotic and abiotic factors of the eastern bluebird near a lake,...

(d) a keystone species. Carnivorous: In both animal and plant classifications, some organisms are carnivorous. Carnivorous organisms are described as flesh or meat-eaters. An example of a carnivore animal is a lion and a cheetah, while a carnivorous...
Disruption of a plant-lizard seed dispersal system and its ecological effects on a threatened endemic plant in the Balearic Islands The introduction of exotic species to an island can have significant effects on the population density and distribution of native species and on the ecolog... A ...
