Biologically, it may also look at coevolution the process by which species actions in an environment affect and influence one another It is, however, increasingly vital to our understanding of conservation issues, species protection and risk mitigation.
Those who work in conservation ecology examine how we might change practices when working in an environment to mitigate the risk of the extinction of a species that relies on that environment to survive. They work closely with or sometimes as conservation biologists, but ecologists are more concerned with the impact of the environment, biodiversity and natural resources as a whole, rather than treating a species and its problems as existing in a bubble Ecophysiology Also known as environmental physiology or physiological ecology, it concerns the effects of the environment on a species' physiology.
In this way, it has some overlap with evolutionary biology by looking at abiological processes, specifically environmental forcings and adaptation, rather than natural drift, and comparative physiology by attempting to explain what environmental impacts may have led to genetic drift between closely related similar species living in slightly different environments. Charles Darwin examined the finches of the Galapagos Islands which were physiologically distinct but still the same species In humans, the study has been used to explain the reason for the great variation in human skin color, largely considered due to levels of sunshine.
Ecotoxicology This small but growing area of ecology examines the ecological role of toxic materials on biological systems - on individuals, species, communities and biosphere levels.
The effects of pollution on life and the environment is an ongoing problem. But rather than looking at pollution from a medical perspective, they examine broad and long-term problems for the environment - both local and large-scale level. Past studies in ecotoxicology that led to the Clean Air Act and the Environmental Protection Agency, to protect biodiversity.
Rachel Carson, a marine biologist and conservationist, writer of Silent Spring inis credited with starting this area of study, separating it from the medical study of toxins Evolutionary Ecology Also Known as Ecoevolution Fusing biology and evolution with ecology, this area of study considers the environmental forcings that affect species evolution. This can include a sudden change in temperature or weather variance, the presence and profile of vegetation in an area to which some of the population has migrated, the impact of predators and prey species and population pressures.
It considers evolution within a community at an individual level and studies what aspects may impact the community. Each individual has a specific set of needs, creating competition which plays off against Darwin's survival of the fittest in terms of species Fire Ecology To many, wildfires are a natural disaster on which governments spend millions tackling and controlling.
Ecologically speaking, there are vital for regenerating those ecological systems that they destroy. Fire ecologists examine the Earth's relationship with fire in natural habitats, how they start and end, why they start in certain areas, frequency and intensity and the area's ecological history with wildfire Functional Ecology This area considers the pragmatic aspects of ecology - the part that certain species play in the broader ecology.
Examples include predator and prey interactions, the study of the roles or functions, dependence and interdependence, that certain species or groups thereof play in an ecosystem to maintain balance within the system.

Modern problems that they might study would include the removal of wildflowers vital to bee population, destruction of habitats vital to prey species that will, in turn, damage predator numbers Global Ecology This is the study of the entire planet as an ecosystem and the micro and macro parts that comprise it.
Our planet is a complex system where events in one area can have either local, regional or planet-wide knock-on effects. Global ecology understands the impacts that weather systemsspecies migration, pollution, natural events and any other localized issues can have on the other side of the planet, not a series of isolated events.
It addresses the macroecological questions such as the effects of large natural disasters, global climate change and ocean acidification In the 21st century, many of its practitioners examine the human impact on the global ecology. Human Ecology Humans are one of the most successful species ever to have evolved on this planet. No species has changed the habitat quite in the way that we have changed it. Human ecology is an interdisciplinary approach looking at the ecological impact on the environment, biodiversity, species and adaptation of human life covering ouryears of existence.
It is defined as the study of humanity's ecological dominance deforestation for agriculture, urbanization and other changescrossbreeding of animal and plant species and the impact that has on natural environments, and interactivity with environments - modification and adaptation. Landscape Ecology It is only relatively recently that we have come to understand the ecology of individual landscapes.
This area of ecology examines the interactions between separate, discrete and disparate elements within a single landscape type as well as its structure, composition and functions within a wider ecology. How a landscape is defined is not always clear, but through the lens of landscape ecology, it is a system containing a specific ecological pattern. It can be a mountain range or a single hill within a wetland.
It can be a freshwater floodplain and its relationship with the river or lake that runs through it Macroecology Between landscape ecology and global ecology, this is the study of large-scale ecological phenomena that cover multiple geographic locations but are not large enough to be considered global. An example of this is continent-wide impacts of effects of a large volcanic explosion.
The eruption caused disruption across a limited but important area of the northern hemisphere. The ecological problems that this caused are macroecological. Marine Ecology and Aquatic Ecology The interest of the ecology of water and aquatic landscapes, marine life, their relationships and interactions - both abiotic and biotic factors.
Experts in this area will look at biological life at the biochemical, cellular, individual, and community. Marine ecosystems are also of interest, including the marine environment as a biosphere as well as external pressure from weather systems, and dry land ecosystems and pressure. Some examine marine geology and geography and the impact of underwater landscape on life and chemical processes Microbial Ecology Microorganisms are vital to all life and defined as those too small to be seen by the naked eye, requiring a microscope.
Specifically, microbial ecology examines the interactions, ecological needs and relationships of three lifeforms: Archaea single cell organisms without a nucleusEukaryota single or multi cell organisms with a nucleusBacteria and Viruses. These lifeforms exist in every ecosystem in the biosphere; no area is untouched from the deepest oceans to the highest mountains. They represent some of the oldest forms of planetary life.
Understanding how they evolved and became other lifeforms could answer many questions about biological life. Paleoecology Landscapes change over time, sometimes through natural processes such as glacier increase or retreat. Such events in the past can have cataclysmic and fundamental changes to ecologies of all sizes, including the biological organisms that live there.
It studies changes to the landscape over geological timeframes and examines extinct animals and plants locally extinct and globallyincluding potential ecological reasons for that extinction, and at natural changes in the land that could have led to change in the biodiversity - immigrant and emigrant species Population Ecology Population pressure is often just one aspect of each subdivision of ecology, but population ecology is concerned with understanding and predicting the dynamics of the spatiotemporal relationship of a single species within an ecological zone.
It considers the impact that population numbers will have on an environment An imbalance of predator-prey relationships where population numbers are unsustainable due to too little prey the predators will go elsewhere, possibly permanently or too few predators the population of the prey species becomes uncontrollable and eats more plant life than is sustainable.
Both are damaging to the environment. In an estuarine setting where a proposed industrial development could impact certain species by water and air pollutionbiologists would describe the flora and fauna, chemists would analyze the transport of water pollutants to the marsh, physicists would calculate air pollution emissions and geologists would assist in understanding the marsh soils and bay muds.
Environmental chemistry Environmental chemistry is the study of chemical alterations in the environment. Principal areas of study include soil contamination and water pollution. The topics of analysis include chemical degradation in the environment, multi-phase transport of chemicals for example, evaporation of a solvent containing lake to yield solvent as an air pollutantand chemical effects upon biota.
As an example study, consider the case of a leaking solvent tank which has entered the habitat soil of an endangered species of amphibian. As a method to resolve or understand the extent of soil contamination and subsurface transport of solvent, a computer model would be implemented.
Welcome to the Journal
Chemists would then characterize the molecular bonding of the solvent to the specific soil type, and biologists would study the impacts upon soil arthropodsplants, and ultimately pond-dwelling organisms that are the food of the endangered amphibian. Geosciences Geosciences include environmental geologyenvironmental soil sciencevolcanic phenomena and evolution of the Earth's crust. In some classification systems this can also include hydrologyincluding oceanography.
To do so, conservation of the endangered species and preventing species extinction to the highest level is of great importance. Managing those stressful situations and taking proper decision in such situations is necessary. Disease management requires proper preparation and mental ability and most of all perfect planning according to the situation demand. Depending on the epidemics and remedy available, quarantine and medication should be planned so that a particular outbreak must not impact a larger population or spread through a vast geographical area.
Ecological Modeling Measuring ecological behavior of a particular component in a real time scenario may be time consuming and requires ample efforts, in several situations results of such ecological experimentation is cumbersome. Mathematical modeling has become a better alternative in such conditions and may provide a deep insight for understanding the interrelation of different ecological components through computation and predict their future issues.
Agent based model, partial differential equations along with other mathematical techniques are frequently used for this purpose. Ecological Succession Ecological succession is refers to the gradual alteration of a species structure habiting in a particular ecological community over a particular time period. The time frame could be in relation to some natural incidence such as natural disaster, mass extinction etc. Ecosystems Different interacting organisms co-dwelling in a particular geographical area and their relation with surrounding environment forms an ecosystem.
Agriculture, Ecosystems and Environment, Ecosystems. Marine and Freshwater Ecosystems, Urban Ecosystems. Environmental Pollution Pollution refers to the alteration of the natural component proportions beyond a threshold limit specified by the assessment committee for a particular region.
Environmental pollutions lead towards destruction of our ecosystem which eventually may become critical factor for our survival in this planet. Evolution Alteration of inheritable traits in a biological population over generations is known as evolution. Understanding molecular evolution has been an interesting branch of science where interdisciplinary approaches are implemented to understand the gradual changes and their impact on a species. Trends in Ecology and Evolution, Molecular Biology and Evolution, Annual Review of Ecology, Evolution, and Systematics, Evolution; international journal of organic Evolution, International Journal of Systematic and Evolutionary Microbiology Invasion Ecology Breaching the territory of a species by another one through migration, influential invasion due to any reason is considered as invasion ecology.
Marine Ecology Marine ecology refers to the ecological conditions dealing with the marine life. As marine ecology is believed as one of the oldest ecology in the planet and is maintained in a different way rather than the terrestrial ecological aspects, therefore, deep insight in marine flora and fauna are important.
