Global effects of land use on Biodiversity

  1. Present focus in ecology and biodiversity scientific researches is to alert policy makers, and public that global biodiversity is declining at an alarming scale. It is true that despite all efforts our understanding of this decline is still limited. Climate change research has taken more attention, more investment will be going in this direction -not realising loss of biodiversity is the crucial link which is bringing this global climate change. In my personal analysis lot of research and investment is needed at plant biodiversity level. Dr.Mrs.Promila Kapoor-Vijay FLS; @kapoorvijayp,;@probio3
  2. Global effects of land use on biodiversity paper by Tim Newbould et al. ,gives very interesting information and useful projection suggesting that human land use has caused substantial declines in species richness. The multi authored paper (Functional Ecology (2020,January) points clearly that our “understanding of nature and drivers of biodiversity decline remains incomplete” and further .. evidence from different taxonomic groups and geographic regions suggests that land use does not equally impact all organisms within terrestrial ecological communities, and that different functional groups of species may respond differently. In particular, large carnivores are expected to decline more compared to other animals due to land use disturbance”.
  3. This paper is first “global synthesis of responses to land use across functional groups using data from a wide set of animal species, including herbivores, omnivores, carnivores, fungivores and detritivores; and ranging in body mass from 2 × 10−6 g (an oribatid mite) to 3,825 kg (the African elephant)”.and authors have shown”that the abundance of large endotherms, small ectotherms, carnivores and fungivores (although in the last case, not significantly) are reduced disproportionately in human land uses compared with the abundance of other functional groups”, further suggesting that certain functional groups are consistently favoured over others in land used by humans.(
