Book Description
At present, less than 30% of researchers worldwide are women. Long-standing biases and gender stereotypes discourage girls and women from pursuing a career in science, technology, engineering and mathematics (STEM) research. Science and gender equality are, however, essential to ensure sustainable development. Although underrepresented, and often unacknowledged, female researchers have been crucial to scientific advances. In order to change traditional mindsets, gender equality must be promoted, stereotypes defeated, and girls and women should be encouraged to pursue STEM careers.

Book Description
Birds have and continue to fascinate scientists and the general public. While the avian respiratory system has unremittingly been investigated for nearly five centuries, important aspects on its biology remain cryptic and controversial. In this book, resolving some of the contentious issues, developmental-, structural- and functional aspects of the avian lung-air sac system are particularized: it endeavors to answer following fundamental questions on the biology of birds: how, when and why did birds become what they are? Flight is a unique form of locomotion. It considerably shaped the form and the essence of birds as animals. An exceptionally efficient respiratory system capacitated birds to procure the exceptionally large quantities of oxygen needed for powered (active) flight. Among the extant air-breathing vertebrates, comprising ~11,000 species, birds are the most species-rich-, numerically abundant- and extensively distributed animal taxon. After realizing volancy, they easily overcame geographical obstacles and extensively dispersed into various ecological niches where they underwent remarkable adaptive radiation. While the external morphology of birds is inconceivably uniform for such a considerably speciose taxon, contingent on among other attributes, lifestyle, habitat and phylogenetic level of development have foremost determined the novelties that are displayed by diverse species of birds. Here, critical synthesizes of the most recent findings with the historical ones, evolution and behavior and development, structure and function of the exceptionally elaborate respiratory system of birds are detailed. The prominence of modern birds as a taxon in the Animal Kingdom is underscored. The book should appeal to researchers who are interested in evolutionary processes and how adaptive specializations correlate with biological physiognomies and exigencies, comparative biologists who focus on how various animals have solved respiratory pressures, people who study respiration in birds and other animals and ornithologists who love and enjoy birds for what they are – profoundly interesting animals.

Book Description
The United Nations has recently released population projections suggesting that the global population will reach 9.7 billion by 2050 and exceed 11 billion by 2100. The increase in the world population may lead to food shortages, especially that of food protein. A variety of food protein alternatives have been developed and launched to the market to solve the problem of diminishing resources, particularly of land and water. In fact, animal protein has become a target in recent times for its greenhouse gas emissions. However, the UN has projected a steady increase in demand for poultry meat over the upcoming decades. The main demand will be from middle class and low-income families in particular and is due mainly to its high production efficiency for inexpensive, good-quality proteins. Nonetheless, due to limited resources, the poultry meat produced must be of high quality to ensure food security and minimize food waste.
