Natality in PopulationEcology is the scientific term for birth rate . Along with mortality rate , natality rate is used to calculate the dynamics of a population . They are the key factors in determining whether a population is increasing, decreasing or staying the same in size. Natality is the greatest influence on a population s increase. Natality is shown as a crude birth rate or specific birth rate. Crude birth rate is used when calculating population size of births per 1000 population year , whereas specific birth rate is used relative to a specific criterion such as age. By calculating specific birth rate, the results are seen in an age specific schedule of births. Definitions Natality Rate number of births per 1000 individuals per year. Absolute Natality the number of births under ideal conditions with no competition, abundance of resources such as food and water, etc . Realized Natality the number of births when environmental pressures come in to play. Animal Natality Specific birth rate is used when calculating animal natality. The criterion used is age.

Unreferenced date December 2009 Orphan date December 2009 Ecology is a broad biological science and can be divided into many sub disciplines using various criteria. Many of these fields overlap, complement and inform each other. Indeed, few of these disciplines exist in isolation. For example, the populationecology of an organism is a consequence of its behavioral ecology and intimately tied to its community ecology . Methods from molecular ecology might inform the study of the population, and all kinds of data are modeled and analyzed using quantitative ecology techniques. When discussing the study of a single species, a distinction is usually made between its biology and its ecology . For example, polar bear biology might include the study of the polar bear s physiology , morphology biology morphology , pathology and ontogeny , whereas polar bear ecology would include a study of its prey species, its population and metapopulation status, distribution, dependence on environmental conditions, etc. In that sense, there can be as many subdisciplines of ecology as there are species to study. Other criteria Ecology can also be classified on the basis of the primary kinds of organism under study, e.g. animal ecology , plant ecology , insect ecology the biomes principally studied, e.g. forest ecology , grassland ecology , desert ecology , benthic ecology , marine ecology , urban ecology the geographic or climatic area, e.g. arctic ecology , tropical ecology the spatial scale under consideration, e.g. macroecology , landscape ecology the philosophical approach, e.g. systems ecology which adopts a holistic approach the methods used, e.g. molecular ecology .

orphan date September 2011 Reverse ecology refers to the use of genomics to study ecology with no a priori assumptions about the organism s under consideration. The term was suggested in 2007 by Matthew Rockman during a conference on ecological genomics in Christchurch, New Zealand . ref cite journal last Li first YF coauthors et al title Reverse ecology and the power of population genomics journal Evolution year 2008 volume 62 issue 12 pages 2984 2994 ref Rockman was drawing an analogy to the term reverse genetics in which gene function is studied by comparing the phenotypic effects of different genetic sequences of that gene. Most researchers employing reverse ecology make use of some sort of population genomics methodology. This requires that a genome scan is performed on multiple individuals from at least two populations in order to identify genomic regions or sites that show signs of selection. These genome scans usually utilize single nucleotide polymorphism single nucleotide polymorphism SNP markers, though use of Microsatellite genetics microsatellite s can work as well with reduced resolution . Methodology Reverse ecology is recently used by researchers to understand environments and other ecological traits of organisms on Earth using genomic approaches. By examining the genes of bacteria , scientists are able to reconstruct what the organism s environments looked like millions of years ago. The data could help us understand key events in the Evolutionary history of life history of life on Earth.

for the scientific journal Molecular Ecology Unreferenced date July 2008 Molecular ecology is a field of evolutionary biology that is concerned with applying molecular population genetics , molecular phylogenetics, and more recently genomics to traditional ecology ecological questions e.g., species diagnosis, conservation and assessment of biodiversity, species area relationships, and many questions in behavioral ecology . It is virtually synonymous with the field of Ecological Genetics as pioneered by Theodosius Dobzhansky , E. B. Ford , and others. Citation needed date July 2010 These fields are united in their attempt to study genetic based questions out in the field as opposed to the laboratory. Molecular ecology is related to the field of Conservation genetics . Methods frequently include using Microsatellite genetics microsatellites to determine gene flow and Hybrid biology hybridization between populations. The development of molecular ecology is also closely related to the use of microarray DNA microarrays , which allows for the simultaneous analysis of the expression of thousands of different genes. real time polymerase chain reaction may also be used to analyze gene expression as a result of changes in environmental conditions or different response by differently adapted individuals. Bacterial diversity Molecular ecological techniques have recently been used to study in situ questions of bacterial diversity. This stems from the fact that many microorganisms are not easily obtainable as cultured Strain biology strains in the laboratory, which would allow for identification and characterisation. It also stems from the development of polymerase chain reaction PCR technique , which allows for rapid amplification of genetic material. The amplification of DNA from environmental ...
