Examples include farms, cities, and reservoirs.Built Environment: This refers to human-created structures and spaces, including buildings, roads, bridges, and parks. These environments are designed to meet human needs and can have significant impacts on the natural environment.Also read: What UPSC Wants from IAS AspirantsUnderstanding the components and types of environments is crucial to prepare for complex topics. Let’s look at ecology and ecosystems next.Ecology and EcosystemsBasic Principles and Types of EcologyEcology is the study of the interactions between organisms and their environment. Its key principles include:Interdependence: Organisms are interconnected and rely on each other for survival. Changes in one population can affect others within the ecosystem.Energy Flow: Energy flows through ecosystems, typically from the sun to producers (plants), then to consumers (herbivores, carnivores, omnivores), and finally to decomposers.Nutrient Cycling: Essential nutrients like carbon, nitrogen, and phosphorus are constantly recycled within ecosystems.Adaptation: Organisms evolve to better suit their environment. These adaptations can be physical, behavioral, or physiological.Carrying Capacity: The maximum number of individuals of a species that an environment can sustainably support.Ecology is a broad field with various specializations. The types of ecology include:Autecology: The study of individual organisms or species and their interactions with the environment.Synecology: The study of groups of organisms (communities) and their interactions within an ecosystem.Population Ecology: Focuses on the dynamics of populations, including size, growth, distribution, and regulation.Community Ecology: Studies the interactions between different species within a community, including competition, predation, and symbiosis.Ecosystem Ecology: Examines the flow of energy and nutrients within ecosystems, as well as the interactions between living organisms and the abiotic environment.Behavioral Ecology: Investigates the ecological and evolutionary basis of animal behavior.Landscape Ecology: Studies the spatial patterns and interactions between ecosystems across a landscape.Functions and Types of EcosystemsEcosystems perform several vital functions:Energy Flow: Capturing solar energy through photosynthesis and transferring it through the food web.Nutrient Cycling: Recycling essential nutrients through decomposition and other processes.Regulation of Climate: Influencing local and global climate patterns through processes like transpiration and carbon sequestration.Water Purification: Filtering and cleaning water through natural processes.Soil Formation and Maintenance: Contributing to soil development and fertility.Support of Biodiversity: Providing habitat for a wide variety of species.Ecosystems are broadly classified into:Terrestrial Ecosystems: Land-based ecosystems, including forests, grasslands, deserts, and tundra.Aquatic Ecosystems: Water-based ecosystems, including freshwater (lakes, rivers, ponds) and marine (oceans, seas, estuaries) ecosystems.Also read: Strategy for Evaluating Your Own UPSC Mains Answers Daily Understanding these concepts will help you link them to questions.

AbstractStudies of the effects of variation in resource availability are important for understanding the ecology of high-latitude mammals. This paper examines the potential of dental evidence (tooth wear and breakage) as a proxy for diet and food choice in Vulpes lagopus, the Arctic fox. It presents a preliminary study of dental microwear, gross wear score, and tooth breakage in a sample (n = 78 individuals) from the Yamal Peninsula of the Russian Arctic. While these measures have each been associated with feeding ecology in larger carnivorans (e.g., proportion of bone in the diet), they have yet to be combined in any study and have rarely been applied to smaller species or those from high latitudes. Arctic foxes from the north and south of the peninsula, and those from rodent peak and trough density periods, are compared to assess impact of changes in food availability across space and time. Results indicate that microwear textures vary in dispersion, with more variation in texture complexity, including higher values (suggesting more consumption of bone), in the rodent-poor period in the north of Yamal. Gross wear scores and tooth breakage are also significantly higher for the north of Yamal than the south. These data together suggest that dental evidence can provide important insights into variation in the feeding ecology of Arctic foxes and potentially into the impacts of changes in food abundance across space and time.

Air breathed in a busy room. Ocean water. Scientists have been able to collect and analyze detailed genetic data from human DNA from all these places, raising thorny ethical questions about consent, privacy and security when it comes to our biological information. The researchers from the University of Florida, who were using environmental DNA found in sand to study endangered sea turtles, said the DNA was of such high quality that the scientists could identify mutations associated with disease and determine the genetic ancestry of populations living nearby. They could also match genetic information to individual participants who had volunteered to have their DNA recovered as part of the research that published in the scientific journal Nature Ecology & Evolution on Monday. “All this very personal, ancestral and health related data is freely available in the environment and is simply floating around in the air right now,” said David Duffy, a professor of wildlife disease genomics at the University of Florida. Environmental DNA has been obtained from air, soil, sediment, water, permafrost, snow and ice cores and the techniques are primarily being used to help track and protect endangered animals. Human DNA that has seeped into the environment through our spit, skin, sweat and blood could be used to help find missing persons, aid in forensic investigations to solve crimes, locate sites of archaeological importance, and for health monitoring through DNA found in waste water, the study noted. However, the ability to capture human DNA from the environment could have a range of unintended consequences — both inadvertent and malicious, they added. These included privacy breaches, location tracking, data harvesting, and genetic surveillance of individuals or groups. It could lead to ethical hurdles for the approval of wildlife studies. Matthias Wienroth, a senior fellow studying social and ethical aspects of genetics in forensics, surveillance and human health at the University of Northumbria in the UK, said the scientists involved in the study had taken the “ethical aspects of their work seriously” and “identified some key issues that are likely to emerge with their findings.” “It is important to preserve human autonomy, dignity and the right to self-determination over personal data. This is difficult if you can’t ask those whose DNA may be collected in the environment (for permission), because there’s probably no way to avoid losing DNA to the environment via skin, hair, and breath,” Wienroth, who was not involved in the research, said via email. He emphasized the need to develop and deploy foresight in genetics and genomics research: “A key issue is that such incidental eDNA findings may make their way into databases that can be compared with user data at other genetics databases, thus undermining informed consent and even customer confidentiality.” Human DNA found in water, sand, air The team at the University of Florida’s Whitney Laboratory for
