Advances in Animal Science and Zoology: Volume 13

The opening chapter of Advances in Animal Science and Zoology. Volume 13 reviews the parasite morphology, genetic variability, transmission dynamics in both intermediate and definitive hosts and the parasite-host relationship, emphasizing the metabolic and physiologic alterations in hosts of Angiostrongylus cantonensis. In the second chapter, nematode biology is examined in the context of understanding the infective juveniles persistence, distribution, and effect on insect populations. Potential entomopathogenic nematodes species are identified by distribution, survival, persistence, infectivity of wide host range. Continuing, the authors attempt to explain how Rocky Mountain elk, generally are considered a northern montane ungulate, survive in the Oscura Mountains, a Chihuahuan Desert range located in south-central New Mexico, US. Additionally, this compilation discusses how the effect of predation on ungulates remains contentious, at least in part due to a lack appreciation for the importance of local environmental conditions on predator-prey relationships. The authors study insect pollinators'''' status of Talbotiella gentii for five years, focusing on the flowers of the trees in five locations, determining that there were no animal pollinators present. This is a major threat and could lead to the extinction of the species. The next section proposes that despite the industrialization of Rourkela, the butterfly diversity at the National Institute of Technology (NIT) campus is not very affected. Moreover, it suggests the need for taking up conservation measures to sustain the butterfly faunal diversity of the NIT campus. Subsequently, catfish are examined due to their potential influence on aquatic ecosystems. The catfish population can dispose of up to 26% of the total fish biomass, therefore it plays an important role in the biomanipulation of many freshwater systems. Methods for capturing catfish are also evaluated. It is determined that the most effective method is the use of long-lines simulating angling with a supporting buoy, as it predominantly results in the fish being caught alive. Only a low mortality rate is connected with the method of long-lines in comparison to other methods. The authors discuss European catfish, a large species with only a few competitors likely tomust be apparent in any locality. Moreover, the additional threat of hybridization between the invasive European catfish and closely related native species is explored. The author''''s attempt to predict the forage potential in three forest tree species based on tree species and size, focusing on species commonly consumed by red deer, namely aspen, goat willow, and rowan. The final chapter presents various types of snakes by geography and clinical manifestations according to known venom toxins, thus allowing clinicians to treat the patient even when specific identification is not possible.
