Environment Biodiversity Basics

Biodiversity encompasses not only species that are unusual, imperilled, or endangered, but also all living things, from people to bacteria, fungi, and invertebrates, to name a few.

The Center for Biodiversity and Conservation considers humans and human cultural variety to be part of biodiversity. The term “biocultural” refers to the dynamic, ever-changing, and interconnected nature of people and places, as well as the concept that social and biological components are inextricably linked. This notion acknowledges that human behaviour, beliefs, and knowledge influence, and are influenced by, the natural systems in which human groups exist. This idea recognises that human behaviour, knowledge, and beliefs have an impact on, and are impacted by, the natural systems in which human groups exist. Because of this linkage, all biodiversity, including land, species and seascapes, and cultural ties to the areas where we live—whether right here or in faraway lands—is vital to our well-being. 

Ecology

Ecology refers to the study of how living things are able to interact with their surroundings. Ecology investigates all of these aspects of an ecosystem, which includes living things like plants, animals, and microscopic organisms, as well as environmental conditions like temperature, rain, and sunlight. Ecology is a comprehensive study that encompasses a variety of disciplines including biology, physics, chemistry, and geology.

Both organisms and their surroundings have an impact on each other. Rain and sunlight affect a plant, but the environment beneath the plant is influenced by the plant as it reduces the amount of light, sheds leaves, lowers the temperature, and so on. Living things also impact one another through competition, predation, and other interactions. Abiotic factors are environmental influences, while biotic factors are biological relationships between living organisms.Environmental variables such as wind exposure, temperature, rainfall, sunlight, and soil nutrients are examples of abiotic influences. The overall atmosphere of a location is determined by a mixture of these variables.

Types of Ecology

Microbial Ecology

Microbial ecology focuses on the cellular level, which is the most fundamental level of life. The first two living kingdoms, Kingdom Monera and Kingdom Protista, are primarily involved. The linkages between microorganisms and their interactions with each other and their environments are made here. Microbial ecology is particularly essential in the study of evolutionary relationships and processes that contribute to the existence of microorganisms (known as phylogeny). These links aid in our understanding of organism-to-organism interconnections. It is particularly interested in DNA and RNA structures since they carry the majority of the information handed down from organisms to their offspring, giving ecologists the data they want.

Behavioural Ecology

This encompasses microbial ecology and is the study of the organism at its most fundamental levels. The fundamental purpose of this sort of ecology is to comprehend the organism’s behaviours, adaptations for those behaviours, reasons for those behaviours as explained through the lens of evolution, and how all of these components interact. 

The key interest in this scenario is the individual organism and all of its subtleties, particularly in terms of attempting to understand how it all fits together to improve the organism’s survival or any advantageous adaptations.

Population Ecology

The next rung on the ecological ladder is population ecology. The population, defined as a collection of organisms of the same species living in the same place at the same time, is the focus of population ecology. Population size, density, population structure, migration patterns, and interactions between organisms in the same population are all taken into consideration.

It seeks to explain the various changes in population dynamics, such as why numbers are increasing and whether this has an impact on other elements of the population, such as density.

Community Ecology

Community ecology examines the community, which is defined as all of the people who dwell in a certain place. This encompasses all of the many species populations. The emphasis is usually on the interactions between the many species, how their numbers and sizes interact, and how changes in one population affect the community’s dynamics. Because of the increased species numbers, animal populations here are subjected to more complex interactions, resulting in dynamics such as trophic relationships (who eats who), space dynamics, migration patterns, and also the vital ecological driving force when it comes to inter/intra species interaction.

Climate Change

Climate change usually affects organisms and ecosystems in both direct and indirect ways. There is ample evidence that biodiversity is reacting to climate change and will also continue to do so in the near future. Phenology, species abundance and distribution, community makeup, habitat structure, and ecological processes are all affected directly.

Changes in the usage of land and other resources are causing indirect effects on biodiversity as a result of climate change. These include habitat fragmentation and loss, over-exploitation, pollution of air, water, and soil, and the introduction of invasive species, which may be more devastating than direct impacts due to their scale, scope, and speed. They will exacerbate ecosystems’ vulnerability to climate change and their ability to provide important services such as climate regulation, clean air, food and water, and flood and erosion control.

Impact of Climate Change

Climate change has a negative influence on human health, the environment, and the economy. Consider the following scenario:

• Heat waves become more common, intense, and last longer as temperatures rise, posing health dangers, particularly for young children and the elderly.

• Climate change has the potential to harm human health by deteriorating air and water quality, increasing the spread of some diseases, and changing the frequency and intensity of extreme weather events.

• Coastal towns and ecosystems are threatened by rising sea levels.

• Water supply, water quality, and hydroelectricity output can all be affected by changes in rainfall patterns and amounts, as well as changes in the timing and amount of stream flow.

• Many animals and plant species’ geographic ranges, as well as the timing of lifecycle events like migration and reproduction, are influenced by changing ecosystems.

• Increases in the frequency and intensity of extreme weather events like heat waves, droughts, and floods can increase property losses, cause costly societal disruptions, and make insurance less affordable. 

Conclusion

Adaptation aids us in preparing for some of the most expected repercussions of climate change by lowering their negative effects on ecosystems and human well-being. Strengthening water conservation programmes, improving stormwater systems, building early warning systems for high heat events, and preparing for greater storms through improved emergency preparedness and response plans are just a few examples of adaptation. Droughts and shifting global rainfall patterns are causing crop failures and rising food costs, resulting in food insecurity and nutritional deprivation for the poor, which can have long-term consequences. These have the potential to devastate livelihoods, cause migration and conflict, and limit possibilities for children and youth.
