Dino Day: An Unnamed Species

Adapted from page 58:

This unnamed species is from the late Upper Cretaceous (Maastrichtian, ca. 72.1–66 Ma) of central Laurasia (present-day European Russia). It is a large tooth that, compared to the other dromaeosaurids, must have been the largest. It was a raptor heavier than a brown bear, capable of killing prey even greater than itself. Recently it has been discovered that the body proportions of dromaeosaurids and velociraptorids were different. They had shorter faces, ser- rated teeth, longer legs, and shorter bodies and tails. All this substantially changes their former popular aspect.

Insect of the Week: Managed & Wild Colonies

Adapted from pages 3-5 of Following the Wild Bees:

Wherever there are honey bees, there exist both managed colonies living in beekeepers’ hives and wild colonies living in tree cavities, rock clefts, and the walls of buildings. While it is true that managed and wild honey bee colonies lead rather different lives— the former are manipulated to produce honey and pollinate crops, whereas the latter are left alone and can do whatever boosts their survival and reproduction— the bees in both types of colonies are virtually identical. The members of these two groups look, function, and act so similarly because the two groups have essentially the same genetic composition. This genetic similarity is a consequence of the frequent swapping of genes between the managed and wild colonies living in the same geographical area. Part of this genetic exchange between the two groups arises because the colonies living in beekeepers’ hives produce swarms that escape and then lead lives in the wild, while at the same time the colonies living in natural abodes produce swarms that beekeepers collect and then install in their hives.

The exchange of genes between managed and wild colonies also takes place in a second, more sensational way: the curious sexual behavior of honey bees. Every queen bee mates on the wing with 15– 20 males drawn from the neighboring colonies living within four or so miles from her home. This shameless promiscuity of queen honey bees evolved because high genetic diversity among a queen bee’s female offspring— that is, the workers in her colony— is essential to her colony’s health. These days, it also has the effect of blending the genes in the managed and the wild colonies living in the same region. Incidentally, this extensive gene flow between managed and wild colonies explains why humans haven’t created distinct breeds of honey bees through selective breeding, analogous to what has been done in the domestication of dogs, horses, and sheep.

Following the Wild Bees: The Craft and Science of Bee Hunting
By Tom Seeley

Following the Wild Bees is a delightful foray into the pastime of bee hunting, an exhilarating outdoor activity that used to be practiced widely but which few people know about today. Weaving informative discussions of bee biology with colorful anecdotes, personal insights, and beautiful photos, Thomas Seeley describes the history and science behind this lost pastime and how anyone can do it. The bee hunter’s reward is a thrilling encounter with nature that challenges mind and body while also giving insights into the remarkable behavior of honey bees living in the wild. Whether you’re a bee enthusiast or just curious about the natural world, this book is the ideal companion for newcomers to bee hunting and a rare treat for armchair naturalists.

 

Dino Day: Therizinosaurus cheloniformis

Adapted from page 50:

The Therizinosaurus cheloniformis (“tortoise-shaped scythe lizard”): Lived during the late Upper Cretaceous (lower Maastrichtian, 72.1–69 Ma) in eastern Laurasia (present-day Mongolia). It was known only for its huge nails, which seemed to be part of the shell of a giant turtle over 3 m long. Later, a few more bones were found, including a practically complete anterior limb that was 2.5 m long. Along with Deinocheirus, they had the largest arms among the theropods. Their nails had the appearance of scythes, which must have been impressive when fully extended. When compared with other therizinosaurids, such as Nothronychus, it is concluded that this arm must have belonged to an animal bigger than an Asian elephant.

Insect of the Week: Defending Honey Bee Colonies

Adapted from pages 243-244 of The Lives of Bees:

Every living system faces a legion of predators, parasites, and pathogens, each of which is equipped with a sophisticated tool kit for penetrating the defenses of its prey or host. In the case of a honey bee colony, there are several hundred species, ranging from viruses to black bears, whose members are forever trying to breach the bees’ defenses. What makes a bee colony so attractive to so many is, of course, the store of delicious honey and the horde of nutritious brood that lies inside its nest. In summer, the combs inside a bee hive or a bee tree typically hold 10 or more kilograms (20- plus pounds) of honey, plus thousands of immature bees (eggs, larvae, and pupae). Moreover, these brood items are neatly packed together in the warm center of the bees’ nest, making them an absolute bonanza for any viruses, bacteria, protozoa, fungi, and mites that succeed in infecting or infesting this host of developing bees. Clearly, a colony of honey bees is an immensely desirable target. It is also a perfectly stationary target. Because a colony’s beeswax combs are a huge energetic investment, and because these combs are often filled with brood and food, a honey bee colony cannot afford to find safety by fleeing its home when threatened. Instead, it must cope with its foes by standing its ground, and usually its succeeds, by drawing on a sophisticated arsenal of biochemical, morphological, and behavioral weapons. 

Given that honey bees have a 30- million- year history, it is likely that most of the relationships between Apis mellifera and its predators and agents of disease are long- established. We can expect, therefore, that colonies living undisturbed in the wild possess defense mechanisms that usually prevent pathogens and parasites from multiplying sufficiently to cause severe disease. Indeed, it is likely that wild colonies of honey bees have perpetual, endemic infections of parasites and pathogens, and it is also likely that symptoms of disease arise in these colonies only when they are weakened by adverse environmental circumstances, such as food shortages or damage to their nests. We will see, however, that the balance of power between the bees and their pathogens and parasites can be upset by intrusive beekeeping practices, and that these practices can lead to severe losses of colonies.

The Lives of Bees: The Untold Story of the Honey Bee in the Wild
By Tom Seeley

Humans have kept honey bees in hives for millennia, yet only in recent decades have biologists begun to investigate how these industrious insects live in the wild. The Lives of Bees is Thomas Seeley’s captivating story of what scientists are learning about the behavior, social life, and survival strategies of honey bees living outside the beekeeper’s hive—and how wild honey bees may hold the key to reversing the alarming die-off of the planet’s managed honey bee populations.

Seeley, a world authority on honey bees, sheds light on why wild honey bees are still thriving while those living in managed colonies are in crisis. Drawing on the latest science as well as insights from his own pioneering fieldwork, he describes in extraordinary detail how honey bees live in nature and shows how this differs significantly from their lives under the management of beekeepers. Seeley presents an entirely new approach to beekeeping—Darwinian Beekeeping—which enables honey bees to use the toolkit of survival skills their species has acquired over the past thirty million years, and to evolve solutions to the new challenges they face today. He shows beekeepers how to use the principles of natural selection to guide their practices, and he offers a new vision of how beekeeping can better align with the natural habits of honey bees.

Engagingly written and deeply personal, The Lives of Bees reveals how we can become better custodians of honey bees and make use of their resources in ways that enrich their lives as well as our own.

Dino Day: Bonapartenykus ultimus

Adapted from page 50:

The Bonapartenykus ultimus (“last claw of the paleontologist José Fernando Bonaparte”) came from the late Upper Cretaceous (Campanian, ca. 83.6–72.1 Ma) of western Gondwana (present-day Argentina). The only known specimen is a female that had two internal eggs called Arraigadoolithus patagonicus. Although it is not known precisely what their food source was, it has been suggested that some were either insectivores or omnivores. So it is not surprising that the largest alvarezsaurids were similar in size to today’s largest mammal insectivore, the yurumí (Myrmecophaga tridactyla), or giant anteater.

Many alvarezauroids are the smallest terrestrial theropods. Even the largest species do not stand out. Patagonykus puertai (“Patagonian claw, by Pablo Puerta”) from the early Upper Cretaceous and Achillesaurus manazzonei (“Achilles lizard of Rafael Manazzone”) from the late Upper Cretaceous, both from the western zone of Gondwana (present-day Argentina), were about 2.8 m long and weighed 30 kg. They were very close in size to Bonapartenykus ultimus, but it is unknown if they were adults. .
