Fascinating #OneHealth study on the effects of #urbanization on #bat reproduction: Urban fruit bats give birth earlier in the season compared to rural fruit bats

Pop-sci article: Due to 'the good life' in the city, urban bats give birth earlier than rural bats

Prof. Yovel explains, "Fruit bats living in cities benefit from favorable environmental conditions, including higher temperatures due to the 'urban heat island' effect and greater food availability, primarily from ornamental fruit trees irrigated year-round." ... However, the researchers emphasize that it remains unclear whether the bats are shortening their pregnancies (a capability known in some bat species) or becoming pregnant earlier. They add that the study opens the door to further research on how urbanization affects mammalian reproductive patterns in general and bats in particular, and how these findings can be used to protect other species in changing ecosystems.

BioMed CentralUrban fruit bats give birth earlier in the season compared to rural fruit bats - BMC BiologyBackground Urbanization is rapidly altering our ecosystem. While most wild species refrain from entering urban habitats, some flourish in cities and adapt to the new opportunities these offer. Urban individuals of various species have been shown to differ in physiology, morphology, and behavior compared to their rural counterparts. While several studies have suggested that urban dwelling alters the reproductive cycle in birds, such evidence currently has not been shown for mammals. Egyptian fruit bats are highly flexible mammals that roost and forage in both urban and rural habitats. Urban-dwelling fruit bats encounter higher average temperatures and a richer supply of food (mainly fruit) during winter. Results Here, we set out to determine whether urban-dwelling fruit bats take advantage of urbanization and reproduce earlier in the annual cycle than rural fruit bats. We sampled ten fruit bat colonies located in different urbanization levels, over 3 years. We monitored the bats’ reproductive state and the size of the pups following parturition. Indeed, we found that urban fruit bats gave birth ~ 2.5 weeks earlier in spring than rural fruit bats. We also found that roosting in urban colonies did not decrease the bats’ reproductive success, in contrast to what has been suggested for some urban birds. Conclusions Our study provides new insights into the adaptation to urban living and its exploitation by one of the most common mammalian groups found in cities worldwide—bats.

"Jacobs wrote in 1958 that large-scale office districts would not revitalize downtowns."

During my recent visit to SF, I noticed that the areas that seemed to be doing the best were the most diversified.

I liked this idea  "the best way to plan for downtown is to see how people use it today; to look for its strengths and reinforce them."
