Effects of human disturbance on cave-nesting seabirds: The case of the storm petrel

2015

We tested the effects of human disturbance in two sub-colonies of Mediterranean storm petrel. We conducted three experiments to measure the capacity of the storm petrels to respond to stress. The part of the colony exposed to human disturbance resulted to be habituated and did not show chronic stress related to anthropogenic disturbance.

Do not disturb the family: roles of colony size and human disturbance in the genetic structure of lesser kestrel

2015

Dispersal and philopatry are fundamental processes influencing the genetic structure and persistence of populations, and might be affected by isolation and habitat perturbation. Habitat degradation induced by human activities could have detrimental consequences on the genetic structure of populations. Therefore, it is crucial to understand the role of human impact in promoting or disrupting the genetic structure. Here, we conducted a genetic analysis using 12 polymorphic microsatellite markers of 70 lesser kestrels Falco naumanni from 10 breeding colonies of two subpopulations in Sicily (southern Italy). Genetic differentiation between the two subpopulations was negligible, and linear dista…
