The first wave of animal geography, known as zoogeography, came to prominence as a geographic subfield from the late 1800s through the early part of the 20th century.. During this time the study of animals was seen as a key part of the discipline and the goal was "the scientific study of animal life with reference to the distribution of animals on the earth and the mutual influence of ...
[26] [27] Again in 2022, a new controversy started when both CBSE and NCERT removed topics regarding Islamic Empires in the class 12 history textbook and chapters like “Challenges to Democracy” in the class 10 political science subject and many others, saying it is necessary to reduce syllabus to reduce examination pressure on students by ...
Biogeography is a synthetic science, related to geography, biology, soil science, geology, climatology, ecology and evolution. Some fundamental concepts in biogeography include: allopatric speciation – the splitting of a species by evolution of geographically isolated populations; evolution – change in genetic composition of a population
Zoogeography is the branch of the science of biogeography that is concerned with geographic distribution (present and past) of animal species. [ 1 ] As a multifaceted field of study, zoogeography incorporates methods of molecular biology, genetics, morphology, phylogenetics , and Geographic Information Systems (GIS) to delineate evolutionary ...

Although the first civilian GPS receivers were developed by Magellan in 1989, they were very large and therefore impractical for animal applications. By the mid-1990s, the larger GPS manufacturing companies created GPS receivers that were smaller, more energy-efficient, and therefore more usable for animal-tracking applications.
There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla. For example, Protura, Diplura, and Collembola are often considered to be the three orders in the class Entognatha. This list should by no means be considered complete and authoritative and should be used carefully.
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. The cause of migration may be local climate, local availability ...
