	3	+Another complexity, however, is the impact of climate change on already highly altered fragmented landscapes outside of protected areas. Over 75 of the Earth's terrestrial biomes now show evidence of alteration as a result of human residence and land use (10). Yet, recent case studies suggest that even in a highly fragmented landscape, all is not lost for biodiversity. ¶ It has long been assumed that in a fragmented landscape, the fragment size and its isolation are important factors in determining species persistence; the smaller and more isolated the fragment, the lower its occupancy. Yet few worldwide studies have attempted to quantify this relation. Prugh et al. (11) compiled and analyzed raw data from previous research on the occurrence of 785 animal species in 12,000 discrete habitat fragments on six continents. In many cases, fragment size and isolation were poor predictors of occupancy. The quality of the matrix surrounding the fragment had a greater influence on persistence: When the matrix provided conditions suitable to live and reproduce, fragment size and isolation were less important and species were able to persist. ¶ This ability of species to persist in what would appear to be a highly undesirable and fragmented landscape has also been recently demonstrated in West Africa. In a census on the presence of 972 forest butterflies over the past 16 years, Larsen found that despite an 87 reduction in forest cover, 97 of all species ever recorded in the area are still present (12). For reasons that are not entirely clear, these butterfly species appear to be able to survive in the remaining primary and secondary forest fragments and disturbed lands in the West African rainforest. However, presence or absence does not take into account lag effects of declining populations; a more worrying interpretation is therefore that the full effects of fragmentation will only be seen in future years.
