Bats: A World of Science and Mystery by M. Brock Fenton, Nancy B. Simmons

By M. Brock Fenton, Nancy B. Simmons

There are greater than 1,300 species of bats—or virtually 1 / 4 of the world’s mammal species. yet earlier than you diminish in worry from those bushy “creatures of the night,” examine the bat’s primary position in our atmosphere. A unmarried brown bat can consume a number of thousand bugs in an evening. Bats additionally pollinate and disperse the seeds for lots of of the vegetation we like, from bananas to mangoes and figs.

Lush, full-color photos painting bats in flight, feeding, and mating in perspectives that express them in unparalleled aspect. The photographs additionally take the reader into the roosts of bats, from caves and mines to the tents a few bats construct out of leaves. A accomplished consultant to what scientists find out about the area of bats, the e-book starts with a glance at bats’ origins and evolution. The booklet is going directly to tackle a bunch of questions regarding flight, nutrition, habitat, copy, and social constitution: Why perform a little bats stay by myself and others in huge colonies? whilst do bats reproduce and take care of their younger? How has the facility to fly—unique between mammals—influenced bats’ mating habit? A bankruptcy on biosonar, or echolocation, takes readers during the approach of high-pitched calls bats emit to navigate and capture prey. greater than half the world’s bat species are both in decline or already thought of endangered, and the publication concludes with feedback for what we will do to guard those species for destiny generations to learn from and enjoy.

From the tiny “bumblebee bat”—the world’s smallest mammal—to the large Golden-Crowned Flying Fox, whose wingspan exceeds 5 toes, A Battery of Bats provides a breathtaking view of 1 of the world’s so much attention-grabbing but least-understood species.

Example text

Judging from specimens collected so far, bat species diversity was greater during the earlier periods (Oligocene/Miocene) than in the later deposits (Pliocene in age) at Riversleigh. This may be due to changes in climate and vegetation. Modern bat faunas are much more diverse in tropical forests than in grassland environments, so perhaps the differences in diversity seen over time at Riversleigh reflect ecological changes. Conversely, preservation may be biasing the composition of these faunas.

There is now, however, compelling evidence that bats are more closely related to carnivores and ungulates (cows, horses, whales) than to colugos or shrews. 10. A fragment of an upper jaw with two molar teeth from the Upper Eocene of Egypt. This fossil represents a bat species never before seen by scientists. Nancy is currently working with paleontologist colleagues to formally describe and name this new taxon, which will also be the basis for a new bat family. The large, bulbous hypocone cusp (indicated by the yellow arrow) is a unique feature of this animal.

5 million years old) of Germany and the Oligocene Riversleigh Deposits (ca. 25 to 4 million years old) in Queensland, Australia. One of the special things about lagerstätten is that they offer a snapshot in time of entire faunas, not just individual species. Much of what is known about the earliest bats comes from these unique deposits. The Green River Formation consists of finegrained sandstone, mudstone and siltstone layers that were deposited in a series of freshwater lakes in what are now the states of Wyoming, Colorado and Utah.
