The photographer who takes a picture is the copyright owner. Once the picture is taken, it is considered copyrighted even if it is still in the camera and has not been printed. Copyright law protects works such as pictures even if they have not been registered with the U.S. Copyright Office.
Population bottleneck followed by recovery or extinction. A population bottleneck (or genetic bottleneck) is a sharp reduction in the size of a population due to environmental events (such as earthquakes, floods, fires, disease, or droughts) or human activities (such as genocide).n consequence of such population size reductions and the loss of genetic variation, the robustness of the population is reduced and its ability to survive selecting environmental changes, like climate change or a shift in available resources, is reduced.
Another phenomena, the bottleneck effect is related to the founder effect and occurs when only a small portion of the original population survives to serve as the sole source of the population. This can be attributed to two phenomena, the clustering effect across time and the founder effect.
