Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment.This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources.
In biology, overabundant species refers to an excessive number of individuals [1] and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
Population control plays an important role in wildlife populations. Based on the species being dealt with, there are numerous ways populations of the wild are controlled. Wildlife contraception is the act of preventing reproduction in the wild, which subsequently decreases populations. An example of this includes the maintenance of deer ...
Wildfire, drought impact wildlife. According to the Pew report, rising temperatures linked to climate change have resulted in drought, extreme wildfires and change in the timing and location of ...
Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services. Habitat destruction has altered nitrogen, phosphorus, sulfur, and carbon cycles , which has increased the frequency and severity of acid rain , algal blooms , and fish kills in rivers and oceans and contributed tremendously ...
In fisheries and wildlife management, population is affected by three dynamic rate functions. Natality or birth rate, often recruitment, which means reaching a certain size or reproductive stage. Usually refers to the age a fish can be caught and counted in nets. Population growth rate, which measures the growth of individuals in size and ...
A deer at a farm. Deer management is the practice and philosophy of wildlife management employed to regulate the population of deer in an area. The purpose of deer management is to regulate the population's size, reduce negative effects of population on the ecosystem, and maintain the integrity of other populations.
[13] [14] The Optimum Population Trust (now called Population Matters) has listed what they believe is the overshoot (overpopulation) of a number of countries, based on the above. [15] In one study [16] published in January 2021 in Frontiers in Conservation Science, the significance of overshoot is discussed.
