Habitat fragmentation is a landscape-level process in which continuous habitats are subdivided into smaller, isolated patches by natural or anthropogenic disturbances, altering spatial configuration without necessarily reducing total habitat area proportionally. It modifies edge-to-core ratios, connectivity, and matrix composition, thereby disrupting ecological flows such as dispersal, gene flow, and trophic interactions. Fragmentation typically leads to smaller population sizes, increased demographic and environmental stochasticity, and heightened vulnerability to local extinction. It also drives community reassembly through edge effects, altered microclimates, and differential species responses based on dispersal ability, habitat specialization, and sensitivity to isolation, making it a central topic in landscape ecology and conservation biology.
Increasing urbanization is linked to a decline in crucial pollinator populations, including nocturnal moths, hoverflies, and bees, according to a new study from the University of Sheffield.
