10 OF THE BEST ENTOMOLOGY BOOKS (THAT I'VE ACTUALLY READ) The Insects. By P. J. Gullan & P. S. Cranston. First published in 1994, Gullan and Cranston’s “The Insects” is a welcome addition to the world of entomological textbooks. It is well written, and presented in a style that makes it more accessible to the less knowledgeable reader LOCOMOTION IN MAMMALS: 9 DIFFERENT MODES OF MOVEMENT EXPLAINEDSEE MOREON EARTHLIFE.NET
BIRD EYES: EXACTLY HOW DOES A BIRD'S VISION WORK? The Avian Eye and Vision A bird’s eye is very similar in its basic structure to a human eye. Though with certain modifications and differences. The eyes make up a much larger percentage of the weight of the head in birds, than in man – I.e., 15% for a common Starling,but only 1% for
15 CRANE SPECIES EXAMINED: THE MOST AMAZING BIRDS ON THE The Cranes The Cranes, family Gruidae, are among the most amazing birds we have on this planet. With their large stature and loud resounding calls, cranes have appealed to mankind whenever we have met. In prehistoric times primitive peoples in Africa, Australia and Europe painted images of cranes in caves. In more recent times, The BIRD NESTS 101: IDENTIFYING DIFFERENT TYPES OF BIRD'S The smallest cup-shaped nests belong to the Hummingbirds and Woodstars, which build perfectly shaped thimble sized nests of moss and cobwebs. Often the female bird flies during the whole construction, hovering here and there while building up the shape. Different birds’ nests take different lengths of time to build. BIRD ORDERS OF THE WORLD Below is a list of the 23 current orders of birds, if the order name is not a link then I have not had time to write anything yet. List of the Orders of the Class Aves: Birds Thank you for visiting Earth Life Central! We hope you enjoyed your reading. As you know, there THE BIRD DIGESTIVE SYSTEM: SALIVA, GIZZARD & ALIMENTARY Digestion as a concept covers the passage of food items into and through the body and includes the elimination of wastes as well as the uptake of nutrients. Birds are often small with high energy needs – and for this reason they can digest food very quickly. This high digestive rate helps young birds grow INSECT CLASSIFICATION AND TAXONOMY 101: COMPLETE GUIDE Uniramia (Insecta): things like beetles, bees and flies. Now the uniramia or class insecta are divided into 28 even smaller, though still pretty large groups called Orders such as: Diptera, Flies; Coleoptera, Beetles; Phasmida, Stick-Insects; Dictyoptera, Cockroaches and Praying Mantids; Hymenoptera, Wasps, Ants FISH EYES 101: THEIR SIGHT & VISION COMPARED TO HUMANS Fish Eyes While water is a better medium for the transmission of sound than air, it is a much worse medium for the transmission of light. Basically, water absorbs light. This means that the further a ray of light travels through water, the weaker or more attenuated it becomes. While we who live in the BIRD MATING STRATEGIES 101 (INCLUDING THE PECULIAR "LEKS Bird Mating Strategies Like all living things, birds reproduce.

In prehistoric times primitive peoples in Africa, Australia and Europe painted images of cranes in caves. In more recent times, The FISH LIFE CYCLE 101: FROM THE LARVAE TO SENESCENCE EXPLAINED The Egg Stage. The Egg is defined as the n=1 stage (n being the chromosome count).. A fish egg, as with all eggs, contains only a single copy of each gene and chromosome – the mother’s genetic heritage. The fertilizing sperm also contains a single copy of genetic material – the father’s contribution. BIRD EYES: EXACTLY HOW DOES A BIRD'S VISION WORK? The Avian Eye and Vision A bird’s eye is very similar in its basic structure to a human eye. Though with certain modifications and differences. The eyes make up a much larger percentage of the weight of the head in birds, than in man – I.e., 15% for a common Starling,but only 1% for
THE BIRD NERVOUS SYSTEM AND BRAIN EXPLAINED The bird’s skull is mostly occupied by eyes – and the brain has to make do with what space it can find in a rather narrow cranium. The brain contacts most of the body through the spinal column/chord, with which it forms the central nervous system. Birds normally have 38 pairs of spinal nerves radiating out to the body along the spinalchord.
BIRD FLIGHT 101: EXPLAINING THE MYSTERIES OF AIRFLOW & THE Bird Wing Shapes Explained. The dynamics of bird flight – like all physical actions – are governed by the laws of physics. In its simplest expression, flying is a balance between two sets of forces. lift and weight, and thrust and drag. Weight is the result of gravity and is reduced as much as possible in birds INSECT ANATOMY 101: THE COMPLETE GUIDE TO INSECT BODY The Insect Nervous System. The insect nervous system consists of a ‘brain’ (the result of the fusion of 3 pairs of ‘ganglia’ ). A pair of slender connectives cords run, side-by-side from SOLITARY WASPS 101: THE BEE WOLF AND OTHER The Bee Wolf. One of my favourite Wasps is the Bee Wolf (Philanthus triangulum).This amazing animal – which is mostly yellow in colour and about the size of a Common Social Wasp – digs a nest hole which is about 1 metre deep.. The hole goes down into the sandy soil at about 30 degrees for the first part, then it straightens out and continues on horizontally. THE BIRD HEART: A LOOK AT THE CIRCULATORY SYSTEM & BLOOD The Bird Heart: A Look At The Circulatory System & Blood. Active flapping flight needs a lot of energy to maintain. This, in turn, necessitates an efficient and effective circulatory system. Birds have evolved such a system and it is very similar to a mammal’s. Bird blood is similar to ours, in that it contains both red (erythrocytes)and
SHIELD BUGS 101: WONDERS OF FAMILIES PENTATOMIDAE & CYDNIDAE The Shield Bugs One of the easiest groups of bugs to find and identify are the Shield Bugs. There are about 6,500 species in the world and about 40 in Britain. In Britain the Shield Bugs are represented by four different families; Cydnidae, Acanthosomatidae, Pentatomidae and Scutelleridae. Generally they are flattish oval or shield shaped TAXONOMIC IDENTIFICATION KEY FOR PREYING MANTIDS This key is based on a translation of the works of Giglio-Tos and Beier. I have in general followed the classification used by Beier, and relied on Giglio-Tos to provide details missing from Beier. There are a number of important limitations: a) The key is entirely derivative, and not based on any original observations by me. SPIDER ANATOMY 101: A LOOK AT THE DIFFERENT PARTS OF A The Anatomy of Spiders Spiders have their body divided into two sections, unlike the other commonly seen group of arthropods – the insects – who have their body divided into three sections. The two sections of the spider body are called the Prosoma or Cephalothorax, which is the head region, and the Opisthosoma or Abdomen BIRD NESTS 101: IDENTIFYING DIFFERENT TYPES OF BIRD'S The smallest cup-shaped nests belong to the Hummingbirds and Woodstars, which build perfectly shaped thimble sized nests of moss and cobwebs. Often the female bird flies during the whole construction, hovering here and there while building up the shape. Different birds’ nests take different lengths of time to build.

When choosing the right stereo microscope types of microscopes, the “best” model is the one that suits your particular needs.

HEMICHORDATA: PHYLUM OF THE AMAZING ACORN WORMS Hemichordates (Acorn Worms) Etymology: From the Greek Hemi for half, and the Latin Chorda a chord. Characteristics of Hemichordata: Bilaterally symmetrical. Body has more than two cell layers, tissues and organs. Body cavity a true coelom. Body possesses a through gut, straight or U-shaped, with an anus. Body divided into three sections, a proboscis, a collar and a LICHEN GROWTH AND DEVELOPMENT EXPLAINED Growth and Development in Lichens Like all living things, lichens need nutrients and energy to grow. Nutrients they obtain from the air (including dust), water and some from the substrate they are growing on. Energy they obtain through photosynthesis, which is the role of the algal partner. They can also be incidentally fertilised by bird HOW DO BATS FLY: THE MECHANICS OF FLIGHT & LIFT EXPLAINED Gliding And Lift During Flying. Lift is generated by a combination of the shape of the wing and the passage of air across it. Basically this is because the wings of bats are not flat, but are shaped like an aerofoil – meaning they are an irregular concave shape. Because of the curvature of the wing, the air that moves over the top of the wing BIRD NESTS 101: IDENTIFYING DIFFERENT TYPES OF BIRD'S The smallest cup-shaped nests belong to the Hummingbirds and Woodstars, which build perfectly shaped thimble sized nests of moss and cobwebs.
