What do Beetles Eat?

What do Beetles Eat?

It depend on the type of beetles.Beetles will eat almost anything, including dead wood, plant material, pollen, nectar, dung, carcasses and food in cabinets. Learn how the only things that beetles will not eat is mineral and metal materials.Many beetles are predatory, which means they prey on smaller animals. They generally eat any small insect, spider, bird or crustacean that they can find. A few species only prey on very specific animals. A few species of beetles eat poo, dead animals and fungi.

Have there Been Bigger Bugs?

Have there Been Bigger Bugs?

Some Paleontologists have discovered fossils of some cockroaches that were far bigger during the Jurassic period than they are today. Scientists aren't really sure why they were bigger back then (wasn't everything?), but it may have had to something to do with the warmer climate. Earth today has warm, tropical zones only around the equator, but during the Jurassic and Triassic periods temperatures around the globe were warmer. If it was the warm climate that contributed to the large size of the ancient species, we may be seeing larger species of beetles appearing as global warming continues. They may even be evolving as we speak.


This gigantic myriapod is an Arthropleura species. Known from the Upper Carboniferous, these huge invertebrates reached 2 meters (6 and a half feet) in length and 48 cm (19 inches) in width. Today's millipedes and centipedes are much smaller, although some tropical species are of moderate size. Werner Kraus constructed this model for the Naturkundemuseum in Augsburg, Germany.


I assume that insects lost their competitive advantage as giants, but I'm not sure why? Introduction of new predators? Food shortages?

Mammalogy


In zoology, mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chamberedhearts, and complex nervous systems. Mammalogy has also been known as "mastology," "theriology," and "therology."

Mammalogy branches off into other taxonomically-oriented disciplines such as primatology (study of primates), and cetology (study of cetaceans). There are many more.

Entomology





Entomology (from Greek ἔντομος, entomos, "that which is cut in pieces or engraved/segmented", hence "insect"; and -λογία, -logia[1]) is the scientificstudy of insects, a branch of arthropodology. At some 1.3 million described species, insects account for more than two-thirds of all known organisms,[2]date back some 400 million years, and have many kinds of interactions with humans and other forms of life on earth. It is a specialty within the field of biology. Though technically incorrect, the definition is sometimes widened to include the study of terrestrial animals in other arthropod groups or other phyla, such as arachnids, myriapods, earthworms, and slugs.

Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect related inquiries is, by definition, entomology. Entomology therefore includes a cross-section of topics as diverse as molecular genetics,behavior, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, paleontology, anthropology, robotics,agriculture, nutrition, forensic science and more.

Tell me , Teach me , Show me

Hi, everyone. I have Some question to ask to all of you who viewing my blog. It about the Zoologist , mammalogist .

Which university have this Career ? What is this Career salary for month if i got Master degree ? and how about i'm a PHD degree?
