  1. 18 Δεκ 2020 · Habitat loss, fragmentation, and degradation impacts are the most direct threat to global biodiversity. In this Primer, we discuss how these three forms of habitat transformation are inextricably intertwined, and how their effects on biodiversity and ecosystems are often context specific.

  2. 25 Νοε 2020 · Deforestation causes radical changes in habitats, nutrient cycling, and species composition since keystone species that define the whole ecosystem are removed. Urbanization may lead to the complete destruction of ecosystems as well as numerous ecosystem disturbances which can further promote the spread of invasive species.

  3. Despite growing interest in assessing the economic impacts of ecosystem degradation (16–18), efforts to quantify these costs are complicated by the difficulties in establishing changes in biodiversity as the cause of economic losses (19, 20).

  4. 25 Νοε 2020 · Natural habitat loss changes habitat functions and results in lack of pollination (loss of pollinators), as well as in lack of compatible pollination through restricted pollinator movement.

  5. 27 Ιαν 2020 · Ecosystems play a major role in both of these scenarios. Extensive and connected ecosystems, species and genetic diversity, trophic intactness and habitat heterogeneity, can buffer the impacts of climate change.

  6. Some economic analyses explore optimal habitat pattern through objectives to minimize fragmentation or through constraints on connectivity, but other economic work on fragmentation does not begin with the assumption that fragmentation is negative.

  7. Habitat disruption refers to the process where species face local extinction due to significant losses in genetic, population, and geographic variation, making them more susceptible to environmental changes and random events.
