Human population density and land use is causing changes in animal genetic diversity, according to researchers at McGill University. The findings reported in the journal Ecology Letters, show that environmental changes caused by humans are leading to changes in genetic variation in thousands of species of birds, fish, insects, and mammals.

To understand if habitat novelty results in different colonization mechanisms and demographic effects, we used Poptools [] to standardize sample sizes to seven individuals per collection site before comparing levels of genetic diversity (using the value 1-Qinter].

The authors attribute the genetic effects to urban-related habitat fragmentation, which restricts movement and therefore gene flow. BUT Their study also analysed data for 25 species, none of which exhibited genetic effects of urbanisation. Neither did the

When habitats become fragmented, the remaining patches of habitat are often far from each other, which isolates individuals and leads to loss of genetic diversity in a population. Fragmentation can alter temperature, wind, amount of sunlight, and water availability

Loss of habitat and fragmentation reduces population sizes and can lower migration rates and genetic connectivity among remaining populations of native species, reducing genetic variability and increasing extinction risk. Restoration of native species and habitats may also be constrained by low genetic variability and often little is known of the genetic implications or the levels of

The inclusion of fluctuating habitat conditions on species dispersal, colonization, and genetic rescue effects is an essential contribution to advance our understanding of metapopulation ecology. Our work emphasizes the importance in expanding investigations of genetic signatures of populations in dynamic landscapes for multiple species, metapopulations, and metacommunities.

Habitat size, LUI and landscape characteristics had only weak effects on most of the parameters of genetic diversity of C. parallelus; only expected heterozygosity and the grasshopper abundances were affected by interacting effects of LUI, habitat size and
