Mexico that you find in New Jersey. Major food crops come from a small number of seed sources.
Marinelli said that while some species of plants and animals need woodlands, some need grasslands, some wetlands but all areas are being broken into smaller parcels. Large chunks of habitat are hard to find. Smaller parcels support fewer species and many organisms have a minimum home-range requirement to successfully breed.
Species concentrated in small areas are also more succeptible to being destroyed. One thing going wrong in a closed community will affect the entire population and can easily affect every , member.
In smaller populations, there is also more inbreeding. Loss of bio-diversity can lead to “genetic meltdown.” Species start to lose their differences and become so closely related, again, they are more susceptible to mass destruction.
Marinelli said that habitat fragmentation can be as subtle as a road cut through a woods. It is well known that ants disperse seeds of many plants. Even a small road or change of topography can prevent them from spreading plant populations into other areas. We need ways of linking areas of similar habitat together to allow species to move about, continue inter-breeding and form new populations.
