A genus of deer, Rangifer, that inhabits the northern parts of Europe, Asia, and America. Caribou is the North American name; reindeer, the European. They are often domesticated and used, especially in Lapland, for drawing sleds and as a source of food. Rangifer is the only genus of the deer family in which both sexes are antlered. Most caribou inhabit arctic tundra and surrounding arboreal coniferous forests and most have seasonal shifts in migration. They are hunted extensively for their meat, skin, antlers, and other parts.

They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.

  • One of the most common conclusions of previous research is that environmental stochasticity is the dominant key compounded driver of population dynamics. (
  • We showed that density dependence explained 37-50% of the total variation in growth rate in three independent datasets, indicating that several non-exclusive density-related mechanisms can be important in monarch population dynamics. (
  • From a population dynamics perspective the two aims are clearly distinct but complementary. (
  • While most previous studies have measured and explained vital rates independent of population size, several processes described above could influence monarch population dynamics operating in a density-dependent manner. (
  • Recent archaeological studies have correlated long-term human population dynamics and major dispersal and range shift events with climate changes ( 1 ⇓ ⇓ ⇓ - 5 ), but their results are mixed regarding the significance of climate in shaping human population processes. (
  • The method of spectral analysis is employed to research the spatial dynamics of urban population distribution. (
  • Simulating the spatial dynamics of urban population is an interesting but a difficult project. (
  • Population is one of the two central variables which can be employed to explore the dynamics of cities [ 9 ]. (
  • Clark's law on urban density can provide a window for us to apprehend the dynamics of urban morphology from the angle of view of population. (
  • Armas C, Pugnaire FI (2005) Plant interactions govern populations dynamics in a semi-arid plant community. (
  • Altered atmospheric composition, associated with climate change, can modify herbivore population dynamics through CO 2 and/or O 3 -mediated changes in plant quality. (
  • And you also need to start getting familiar with this kind of notation, because in population dynamics and ecology it is used pervasively. (
  • In Italy, to study the distribution and bionomics of indigenous anopheline populations and to assess environmental parameters that could influence their dynamics, an entomological study was carried out in 2005-2006 in an at-risk study area. (
  • Here, we develop general theory for the density-dependent population dynamics of mutualism based on the C-R mechanism of interspecific interaction. (
  • However, due to the basic nature of C-R interactions, certain density-dependent conditions can lead to C-R dynamics characteristic of predator-prey interactions, in which one species overexploits and causes the other to go extinct. (
  • Consistent with empirical phenomena, these results suggest that the C-R interaction can provide a broad mechanism for understanding density-dependent population dynamics of mutualism. (
  • 2015). There are no other specific reports about biomass evaluation or population dynamics that offer information for a sustainable use of the resource. (
  • Although other factors such as pack competition, disease and human-caused mortality can influence wolf population dynamics, prey density typically determines the carrying capacity for wolves. (
  • However, even more interesting is the dynamics of the population. (
  • This article is provided from a perspective of COVID-19 death rates by categories of county urban, rather than total county densities, through July 8, 2020, based on data published by . (
  • To provide estimates of population density for the years 2000, 2005, 2010, 2015, and 2020, based on counts consistent with national censuses and population registers with respect to relative spatial distribution, but adjusted to match United Nations country totals. (
  • SEDAC assessed and gave a forecast of the population size and density in 2000, 2005, 2010, 2015, 2020. (
  • In many regions, they have been widely exploited for traditional food and medicinal purposes, which has led to a rapid decline of their natural populations, mainly in the Indo-Pacific, the traditional fishing grounds. (
  • Hence, there is a need for more knowledge about how different processes occurring in natural populations affect the effective size of populations, and the Ne/N ratio. (
  • Thus, it is crucial to empirically evaluate whether such a density-dependent pattern occurs in natural populations. (
  • As with most invertebrate species, monarch butterfly population growth rate is affected by environmental stochasticity. (
  • Because of complex cumulative culture, human populations are often considered to be divorced from the environment and not be under the same ecological forcing as other species. (
  • However, these questions have rarely been addressed for preindustrial human populations, despite the fact that these populations provide a rare opportunity to investigate drivers of the distribution and abundance of a single species along global environmental gradients. (
  • Population density affects growth rate by determining how likely is it that an organism will interact with a member of its own species compared to an organism of a different species. (
  • We also apply common data collection and analytical techniques in the field and evaluate their ability to estimate density of a globally widespread species. (
  • In particular, scale of movement impacted estimators substantially, such that area covered and spacing of detectors (e.g. cameras, traps, etc.) must reflect movement characteristics of the focal species to reduce bias in estimates of movement and thus density. (
  • The difficulty to locate mates and overcome predation can hamper species establishment and population maintenance. (
  • Most transient behavior leads to an equilibrium of mutualistic coexistence, at which both species densities are greater than in the absence of interactions. (
  • In fact, there is not enough information about the density, biology, and ecology of the species fished to allow the design of management plans for a sustainable exploitation. (
  • In 2007, Rodriguez-Gil (2007) described the potential of the fishery and mentioned the same species distributed along the Yucatan coast, whereas LopezRocha (2011) evaluated the weight-length relationship and assessed population density in Sisal, recently, other studies have been realized in Yucatan coast (Hernandez-Flores et al. (
  • Therefore, the aims of this study were: 1) to determine sea cucumber density in the fishing area, and 2) to offer information related to the population parameters in order to understand the species biology. (
  • This was a robust result both for monoecious (i.e. hermaphroditic) and diecious (two-sex) species, and suggests that small (sparse) populations are able to resist further losses of genetic variation. (
  • Density estimates for individual species show that responses vary among species, and boreal species can maintain high densities in southern habitats even during shifts in the northward edge of distribution. (
  • Problems tend to arise primarily when populations become so dense as to cause overcrowding . (
