The critical role of honeybees as pollinators is highlighted, emphasizing their significant economic impact on American agriculture. The book delves into the health challenges facing bee colonies, particularly focusing on viral infections like deformed wing virus and acute bee paralysis virus, which contribute to colony collapse. It explores the distribution of various viruses within honeybee reproductive castes and suggests that environmental factors may trigger viral outbreaks, affecting the overall health of bee populations.

The research investigates gastrointestinal helminthes parasites in working equines in Peshawar, Pakistan, highlighting their prevalence among horses, donkeys, and mules. The study, conducted from September 2010 to January 2011, involved analyzing fecal samples and found that younger equines showed stunted growth due to higher susceptibility to these parasites. Results indicate a moderate to low infestation rate, emphasizing the need for improved management practices and education among equine owners to enhance the health and efficiency of these important animals.
A survey of 29 wetlands in the Fraser River of British Columbia suggested that red-eared slider turtle, Trachemys scripta elegans is well established and more widely distributed. Their history, habitat requirements, relative density, size distribution were coexisted with the Western painted turtle, Chrysemys picta bellii. According to the International Union for Conservation of Nature (IUCN), invasive species are one of the most important causes of biodiversity decline at a global scale. Pet voluntary introductions are made by public and usually concern only one or two individuals per occasion. Hatchling of T. s. elegans has been massively exported from the United States America (USA) to European and Asian countries to be sold as pets. Recent studies with T. s. elegans have shown that exogenous estradiol-even when applied to eggshell was affecting sex development during embryogenesis. Aroclor produced most powerful effects, shifting the ratio of females almost twofold. The daily and seasonal changes in ventilation and breathing pattern resulted solely from daily and seasonal oscillations in metabolism or also from changes in chemo-reflex sensitivity.
