  • world's population
  • Promoting better market access and market performance for smallholder agricultural producers and the provision of access to better quality and lower price food for the majority of the world's population requires the strengthening of rural-urban linkages and putting 'place-based development' at. (fao.org)
  • Although this slow rate of decline satisfies the Millennium Development Goal (MDG) for TB, which is to ensure that the incidence rate is falling by 2015, the world's population is growing at about 2% per year, so the total number of new TB cases is still rising ( 1 ). (sciencemag.org)
  • Research
  • Research into the dynamics of ecological populations allows us to understand the conservation of endangered species, make predictions about the effects of global climate change and understand the population fluctuations observed in the natural world. (warwick.ac.uk)
  • Previous investigations of population oscillations have utilized primarily two distinct approaches: potential mechanisms have been investigated with mathematical models, while data patterns have been investigated with phenomenological time-series analyses (cycles have also been investigated experimentally, but this approach is not part of our proposal because it falls outside of the scope of the research supported by the Center). (ucsb.edu)
  • Research also examines factors that may affect population parameters such as energy intake or disease. (gc.ca)
  • Application of USGS research to restore a second population of the species has been viewed as one of the most successful applied research/conservation projects in decades. (usgs.gov)
  • The models will be applied to research the movements and population connectivity of blue crabs in the Northern Gulf of Mexico. (tulane.edu)
  • Blue crabs are an ecologically and economically important species and there are many possible applications of the research including connections with fisheries management, food web analysis, population genetics, and research into the effects of the Deepwater Horizon oil spill. (tulane.edu)
  • health
  • The CPD brings together leading population researchers from disciplines across social science and health fields, including demography, economics, epidemiology, and sociology as well as computer science, geography and social work. (mcgill.ca)
  • The Population Dynamics Option (PDO) is a cross-disciplinary, cross-faculty graduate program offered as an option within 5 existing Master's and doctoral programs in the departments of Sociology, Economics, and Epidemiology, Biostatistics, and Occupational Health (EBOH) at McGill University. (mcgill.ca)
  • interaction
  • Failure to consider the indirect positive interaction in this system would lead to a gross underestimate of the strength of competition, and would not reveal the critical im- portance of the indirect mutualism in maintaining local populations of the inferior com- petitor. (mendeley.com)
  • parameters
  • Together, these population parameters, or characteristics, describe how the population density changes over time. (encyclopedia.com)
  • The values of these four population parameters allow us to determine whether a population will increase or decrease in size. (encyclopedia.com)
  • In addition to information on the number of pups born, and reproductive parameters, model inputs include removals from the population due to incidental catches by the fishing industry, the number of animals that are removed from the population by subsistence, and commercial harvesting, and also a factor that corrects removals by hunters for animals that may have been struck or killed but not recovered or reported. (gc.ca)
  • We discuss the asymptotic dependence of the variability of the population on different parameters, representing the severity or the fluctuations of the environment. (springer.com)
  • natural
  • We will also consider how closely population data from laboratory experiments and from studies of natural populations in the wild fit these models. (encyclopedia.com)
  • The Denali Caribou Herd is ideal for studying natural factors that influence caribou populations because the herd ranges almost entirely within Denali (see map on reverse), where human harvests of large predators (wolf, grizzly bear, black bear) and their ungulate prey (sheep, moose, caribou) are minimal, so natural processes predominate. (nps.gov)
  • degrees
  • However, during the multiplication process of bacteria, there are high degrees of individuality or phenotypic heterogeneity in populations of genetically identical cells [ 2 - 5 ]. (hindawi.com)
  • intrinsic
  • There are many potential explanations for oscillatory population dynamics (in the general sense), with some focusing on intrinsic factors, but most often invoking some aspect of consumer-resource interactions (we briefly review some theoretical and empirical mechanisms by which population cycles can arise in Section 11). (ucsb.edu)
  • data
  • These interactive graphics reflects data from PRB's 2014 World Population Data Sheet. (prb.org)
  • apply a combination of modeling and statistical techniques to a number of data sets (Section IV) in an attempt to determine which of the possible theoretical mechanisms may be responsible for population oscillations in each particular case. (ucsb.edu)
  • develop
  • PRB worked with the Population Unit of the Division of Development Planning at the Ministry of Finance, Economic Planning and Development and the Family Planning Association of Malawi to develop infographics on population and development for Malawi's 28 districts. (prb.org)
  • attempt to develop general statements about mechanisms that are responsible for cycles in nature, and the conditions under which different mechanisms may operate and different types of oscillatory dynamics may arise. (ucsb.edu)
  • determine
  • The harp seal population is monitored through a combination of aerial surveys that determine how many pups are born in a year, and the collection of seals by hunters to obtain information on age at maturity and age specific reproductive rates. (gc.ca)
  • A population model is then used to determine total population size. (gc.ca)
  • survival
  • Since 1986, Dr. Adams has focused on annual assessments of the herd's basic population dynamics (herd size and trend, adult sex composition, adult female survival, and calf production and survival). (nps.gov)
  • The radiocollars allow Adams to periodically locate caribou within the herd for population surveys, as well as to monitor the productivity and survival of individual caribou. (nps.gov)
  • Over the years, Adams has been able to connect population size of the Denali Herd with winter severity (snow depth) and calf survival, as well as the age structure of cows (older cows are more prone to mortality and produce fewer calves). (nps.gov)
  • momentum
  • Before then, a population can continue to grow with the total fertility rate at or below 2.1, depending on its age structure, a manifestation of the concept of population momentum described earlier. (learner.org)
  • model
  • The first and most basic model of population dynamics assumes that an environment has unlimited resources and can support an unlimited number of individuals. (encyclopedia.com)
  • To study the relationship between antimicrobial resistance and the concentration of antibiotics, a competitive population dynamical model is proposed between the susceptible strain and the resistant strain with antibiotic exposure. (hindawi.com)
  • In this paper, based on the above mentioned mechanism of bacterial antibiotic resistance within the host, a competitive population dynamical model is proposed to explore the competitive interactions between the susceptible strain and the resistant strain with antibiotic exposure. (hindawi.com)
  • In the next section, the proposed model is described and the global dynamics is obtained. (hindawi.com)
  • We introduce a simple model describing the evolution of a population of information-carrying macromolecules. (springer.com)
  • countries
  • While most Latin Americans live in urban areas, distinct rural societies persist, especially in countries with large indigenous populations. (prb.org)
  • change
  • Population change in Latin America is important to the United States as globalization strengthens the hemisphere's social and economic ties, and because migrant streams have brought more Latin Americans to U.S. communities. (prb.org)

  • The harp seal is the most abundant seal in the Northwest Atlantic Ocean, with an estimated population of 7.4 million animals in 2013. (gc.ca)
