A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. The term can refer to either the natural environment or the built environment. In ecology, a habitat is the place where an organism lives, which provides food and shelter for the organism and its offspring, as well as affecting its ability to find mates and reproduce successfully. A species’ habitat requirements are those specific conditions that must be met in order for it to persist in an area over time; these include both abiotic (non-living) and biotic (living) factors. Abiotic factors include such things as water availability, temperature range, soil type, and sunlight levels. Biotic factors include predation pressure from other organisms (including humans), competition for resources with other members of the same species or different ones, parasites and pathogens that may infect the organism, and mutualistic relationships with other organisms (e.g., symbiosis).
Habitat loss is one of the main drivers of biodiversity decline worldwide. It occurs when natural habitats are converted or degraded by human activities such as agriculture, urbanization, logging, mining, etc. This can lead to decreased populations of plants and animals within those habitats as well as reduced genetic diversity within species (as fewer individuals are available to contribute genes to future generations). Habitat fragmentation – i.e., the breaking up of large continuous habitats into smaller patches – can also have similar effects on biodiversity. As patch size decreases and distance between patches increases, it becomes more difficult for individuals to disperse between them (resulting in reduced gene flow between populations), which can further increase genetic differentiation among them over time. Additionally, small patches are more susceptible to edge effects from their surroundings than larger ones – e.g., they may experience higher rates of predation from predators that live outside the patch but venture in at its edges looking for prey; they may also have greater difficulty maintaining optimal microclimatic conditions within their borders due to greater exposure to extreme temperatures at their edges than would be found in larger patches further away from any given edge effect boundary .
One way humans have attempted to mitigate some of these negative impacts of habitat loss/fragmentation is through creating nature reserves – i.e., protected areas set aside specifically for conservation purposes where human activities are restricted or managed so as not minimize disturbance to natural ecosystems . However , even when well-managed , nature reserves cannot always prevent all forms of habitat loss/degradation within their boundaries ; they also often fail to adequately represent all types
