Scientists, especially those who deal with long time scales, tend to demark the passage of time that somehow defines a chunk of time. Eons are the longest time spans. The first is described as the Hadean, the first 600 million years defining the formation of the earth. Eons are divided into Eras, then Periods, Epochs, and Ages.
The Carboniferous Period as just one example is a roughly 60 million year period during which the planet was very warm and resulted in the formation of much of the coal on the planet due to photosynthetic removal of carbon from the atmosphere.
The time of dinosaurs is known as the Jurrasic Period, divided into three different Epochs. Our current Epoch is the Holocene which incorporates the time since the end of the last glaciation about 12,000 years ago. The current Age within this Epoch has come to be called the “Anthropocene” which roughly means the period of human influence.
Now, due to the global pandemic and resultant slowing of human activity, some have described our current time as an “Anthropause. “
Global tourism has been radically reduced not just in cultural centers such as cites but also in parks and natural areas. Locales normally frequented by humans have recently been left to wildlife as shown by both urban cameras and trail cams in rural areas. As a result, many wildlife scientists are scrambling to study the movements and actions of life in the temporary absence of humans.
A number of unique experiments are in progress. In Manitoba, Canada ornithologists are studying birds near now much quieter airports. Also, studies are examining low flying birds near highways to see if behavior is changing, albeit for short periods.
Ecologists at the Galapagos Marine Reserve are studying the movements of shy fish that now can move about in the absence of tourists engaged in diving and snorkeling. In the French Polynesian Islands, the impact of extended darkness near seaside hotels is being examined.
Even the open oceans are ripe for study. Reduced tourism and shipping may have an impact on whales. A research group off the coast of Monterrey, CA is collecting samples of whale blubber via specially designed crossbows. The blubber will reveal among other things the amount of cortisol in the animals, an indicator of stress.
Endangered species such as large mammals; rhinoceros, elephants, etc. may be at greater risk from poaching due to the absence of tourists. Although this research is happening during a time of great expense to both human life and the global economy, it is a once in a lifetime pause or at least hopefully so.
