The Life Cycle of the Whiskers and Antennae of Animals and Insects 

This article explores the various chemical, cellular, and molecular mechanisms relevant to the life cycle of whiskers (barbels) and antennae. The growth of zebrafish barbel is characterized by elongation, vasculature development, and innervation of taste buds. Catfish barbels perform chemical and mechanical sensing; namely, their hyper-sensitive gustatory system enables catfish…

Mathematical Modeling of the Molting Process

Abstract Molting is a crucial and intricate process requiring the timely shedding of an animal’s body part, which may include the epidermis, the pelage, or the entire exoskeleton. The unique mechanisms governing the molting cycles of different species can be quantitatively analyzed to predict patterns and behaviours based on key

Feedback Loops and Circadian Rhythms in Parturition and Hatching

Abstract Birthing is the process that keeps animals involved within evolution. Nature encourages animals to reproduce and to allow their offspring to prolong the life of their species. These intricate processes of parturition and hatching are based on mathematical concepts such as feedback loops, where stimulus generates stimulus, and circadian

Functional Interpretations of Chemotaxis in Migrating Organisms

There are many functional applications of chemotaxis that form the stepping stones of animal migration. Investigating trophic chains – dynamic networks of interacting species – reveals how migration and changes in population density shift environmental conditions of an ecosystem. It was shown how fish and algae populations can reduce extinction…

Evolution of Mammary Glands and the Biomechanics of Mammalian Lactation

Lactation constitutes an important aspect of mammalian physiology and reproduction and is a key trait that defines mammals. The evolution of lactation is a story of great controversy, however, and the main theories behind the apparition of mammary glands will be discussed in the following paragraphs. In addition, the origin…

The Biochemical Basis for Olfaction

Often, only the sense of sight and hearing are considered essential to understanding the world in which humans live in. In practice, however, the sense of smell, or olfaction, plays an important role in everyday tasks that are taken for granted. For example, the ability to taste food is highly…
