ants and aphids) but also between insects and microorganisms, between insects and vertebrates, and between insects and plants. Researchers’ simulations suggest that small population sizes and inbreeding made Neanderthal populations vulnerable to chance fluctuations in population size. These are some of the broad, albeit critically-important topics that are covered in this section. A 27-year-long study finds insect biomass has declined by about 75 percent. It may contain individuals of different ages and its size (density) is likely to change over time, growing or shrinking according to the reproductive success of its members. Population Dynamics. These species outnumber all other animals in many terrestrial habitats and, despite their small size, they usually play dominant roles in community ecology, both as consumers and as decomposers. Latecomers encounter a depleted resource that may no longer support growth and development. Geometric growth is also known as exponential growth because the larger the population gets, the faster it grows. Anemones keep their algae populations in check. Ants and termites, for example, produce large numbers of small, expendable offspring but they have long-lived colonies that are highly competitive in stable environments. © 1986–2020 The Scientist. 1990). This Frontiers in Ecology and Evolution section addresses all aspects of population dynamics, with emphasis on species interactions, organism-environment relationships, how novel selection pressures change population dynamics, the roles of plasticity and adaptation in population resilience, limiting and regulating factors, numerical cycles and stability, and demographic processes. Interspecific competition occurs whenever the niche parameters of two (or more) different species overlap. In the last year, the butterfly’s eastern group has more than doubled its hibernation area while the other population waned. ecologyandevolution.editorial.office@frontiersin.org, For queries regarding Research Topics, Editorial Board applications, and journal development, please contact With a 5% growth rate, for example, a population of 50 beetles would grow by only 31 individuals in 10 generations whereas a population of 10,000 would grow by 6,289 during the same amount of time. The population's intrinsic growth rate ("r") is similar to the bank account's interest rate -- it is a measure of how quickly the increase occurs. Last Updated: 25 March 2016 Since only the strongest (most "fit") individuals are likely to hold a territory, they have the best chance to pass on their genes to the next generation. © 2016 by John R. Meyer mutualism and commensalism) are also common in the insect world. Such factors, known as secondary ecological events, may affect the frequency, extent, magnitude, or duration of a primary ecological event. Eastern Monarchs Flourish While Western Numbers Plunge. ecologyandevolution@frontiersin.org, Tel +41(0)21 510 17 10 The niche is a Gestalt-like concept encompassing all of the biotic and abiotic parameters that determine where a population lives (its "habitat") as well as the role it plays within the food web (its "profession"). Interspecific competition usually leads to one of three possible evolutionary outcomes: Density-dependent emigration (movement away from crowded conditions) is another important regulator of population size. r- and K-selection. In practice investigations and theory on population dynamics can be viewed as having two broad components: first, quantitative descriptions of the changes in population number and form of population growth or decline for a … Scientists are struggling to find out why, before it’s too late. Congratulations to our authors, reviewers and editors across all Frontiers journals – for pushing boundaries, accelerating new solutions, and helping all of us to live healthy lives on a healthy planet. It may contain individuals of different ages and its size (density) is likely to change over time, growing or shrinking according to the reproductive success of its members. Intraspecific cooperation has certainly contributed to the evolutionary success of all social insects (ants, bees, wasps, and termites). They exploit disturbed or unstable environments, take full advantage of transient resources, produce large numbers of offspring in short periods of time, and rapidly disperse into new habitats when conditions turn unfavorable. In the long term, emigration benefits the individuals who remain behind as well as the pioneers who find new places to live. All rights reserved. It not only reduces overcrowding in the home range, but it also increases the likelihood of establishing new populations elsewhere. The first arrivals encounter the best conditions for survival and reproduction (first come, first served). Joel Cohen uses the tools of mathematics to deconstruct questions of life.
