Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...

Multi-species Conserved Sequences

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...

Mutation, Gene Flow, and Genetic Drift

Mutation, Gene Flow, and Genetic Drift

In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).Mechanisms of Genetic VariationThe original sources of genetic variation are mutations,...

What is Conservation Biology?

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Gene Evolution - Fast or Slow?

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Area of Science:

Evolutionary Biology
Genetics
Conservation Science

Background:

Conservation genetics has advanced from theoretical population biology to an empirical discipline over two decades.
Technological progress in molecular genetics enabled widespread use of neutral markers (e.g., microsatellites) for assessing genetic drift, inbreeding, and gene flow.

Purpose of the Study:

To highlight the transition from conservation genetics to conservation genomics.
To explore how genomic approaches provide insights into selectively important genetic variation.
To understand the interplay between functional genetic variation and environmental conditions.

Main Methods:

Utilizing neutral molecular markers like microsatellites for population genetic analyses.
Employing advanced genomic techniques such as next-generation sequencing and whole-genome scans.
Analyzing gene-expression patterns to assess functional genetic variation.

Main Results:

Genomic techniques allow genome-wide estimation of functional genetic variation, moving beyond limited neutral markers.
This transition enables deeper insights into the dynamics of adaptive variation.
Facilitates understanding of how environmental conditions interact with genetic variation.

Conclusions:

Conservation genomics offers a more comprehensive approach to studying genetic variation in populations.
Understanding functional genetic variation is crucial for effective conservation strategies.
The integration of genomics provides mechanisms for how populations adapt to changing environments.
