Adverse effects of habitat fragmentation to populations/species: habitat fragmentation creates landscapes made of altered habitats or developed areas fundamentally different from those shaped by natural disturbances that species have. The impact of habitat disturbance on non-human primates remains disputed within the scientific community while some studies report that disturbance decreases.
The negative effects of habitat disturbance on macrofauna as seen in the cleared plots of the present study, may be attributed to changes in vegetation and soil microclimate the two primary determinants of soil biodiversity (decaëns et al 2006). It is widely expected that habitat destruction in the tropics will cause a mass extinction in coming years, but the potential magnitude of the loss is unclear existing literature has focused on estimating global extinction rates indirectly or on quantifying effects only at local and regional scales. 9 flora and fauna impacts habitat and habitat fragmentation) (iv) disturbance of fauna associated with site clearance, road construction, building. The first disturbance model incorporated a single change in survival rates, following the disturbance, whereas the second disturbance model incorporated three survival rates: pre- and postdisturbance, as well as a short-term decline during the disturbance. Causes of riparian-zone degradation riparian-zone disturbance falls into two main categories: hydrologic modifications that indirectly impact riparian communities through changes in stream morphology and hydrologic processes, and habitat alterations that result in direct modification of riparian communities through land clearing or disturbance.
