Zoology

"ZOOLOGY, n. The science and history of the animal kingdom, including its king, the House Fly (Musca maledicta). The father of Zoology was Aristotle, as is universally conceded, but the name of its mother has not come down to us. Two of the science's most illustrious expounders were Buffon and Oliver Goldsmith, from both of whom we learn (L'Histoire generale des animaux and A History of Animated Nature) that the domestic cow sheds its horn every two years."

"Even village women and children know that the unicorn is a lucky sign. But this animal does not figure among the barnyard animals, it is not always easy to come across, it does not lend itself to zoological classification."

"Another immense service rendered by Dalton, as a corollary of the new atomic doctrine, was the creation of a system of symbolic notation, which not only made the nature of chemical compounds and processes easily intelligible and easy of recollection, but, by its very form, suggested new lines of inquiry. The atomic notation was as serviceable to chemistry as the binomial nomenclature and the classificatory schematism of Linnæus were to zoölogy and botany."

"These people call what they do "cryptozoology" — "-zoology" meaning "the study of animals", and "crypto-" meaning "shit we made up"."

"So far as happiness is concerned it matters very little what one wants; the main thing is that one should get it. Besides, zoology makes it clear that a sum of reduced individuals may very well form a totality of genius."

"Logic, I should maintain, must no more admit a unicorn than zoology can; for logic is concerned with the real world just as truly as zoology, though with its more abstract and general features."

"It is not clear that people have fully taken on board the idea that humans are animals. If they had, then perhaps academic disciplines such as sociology and anthropology would be viewed as specialist branches of zoology; medical doctors would be viewed as a subtype of veterinarians (one that specializes in tending to the health needs of just one species); human rights would be viewed as a subset of animal rights; and the socialization of children would be viewed as one example of the training or domestication of animals (making parents and teachers a subtype of animal trainers)."

"Hunting by humans played a major role in extirpating terrestrial megafauna on several continents and megafaunal loss continues today in both terrestrial and marine ecosystems. Recent declines of large marine vertebrates that are of little or no commercial value, such as s, s and s, have focused attention on the ecological impacts of , in global fisheries. In spite of the recognition of the problem of bycatch, few comprehensive assessments of its effects have been conducted. Many vulnerable species live in pelagic habitats, making surveys logistically complex and expensive. Bycatch data are sparse and our understanding of the demography of the affected populations is often rudimentary. These factors, combined with the large spatial scales that pelagic vertebrates and fishing fleets cover, make accurate and timely bycatch assessments difficult. Here, we review the current research that addresses these challenging questions in the face of uncertainty, analytical limitations and mounting conservation crises."

"may act as both and . They influence local environments and s, determine related ecosystem processes and functions, and are associated with high levels of biodiversity. However, the intrinsic characteristics of megafauna species including long lifespan, large body size, sparseness and/or rarity, late maturity, and low fecundity, as well as high market value, make them very prone to extinction. Up to now, scientific interest and conservation efforts have mainly focused on terrestrial and marine megafauna, while freshwater species have received comparatively little attention, despite evidence suggesting that freshwaters are losing species faster than marine or terrestrial realms. The high susceptibility of freshwater megafauna to multiple threats, coupled with immense human pressure on freshwater ecosystems, places freshwater megafauna amongst the most threatened species globally. The main threats include , dam construction, , , and ."

"We identified a total of 362 extant megafauna species. We found that 70% of megafauna species with sufficient information are decreasing and 59% are threatened with extinction. Surprisingly, direct harvesting of megafauna for human consumption of meat or body parts is the largest individual threat to each of the classes examined, and a threat for 98% (159/162) of threatened species with threat data available. Therefore, minimizing the direct killing of the world's largest vertebrates is a priority conservation strategy that might save many of these iconic species and the functions and services they provide."

"Zoos worldwide are visited by great numbers of people, and many of these visitors prefer to see large, rare mammals, the so-called . Zoos and the researchers who use them also appear to prioritise these species, as evidenced by the number of scientific publications which investigate the welfare of charismatic rather than non-charismatic species. However, the charismatic animals also attract more welfare-related concern from groups and the media than the non-charismatics. To this extent the charismatics could be regarded as problematic animals in the zoo. ... However, there is also evidence that their popularity helps zoos achieve their conservation mission, both by increasing funding available for field conservation and by contributing towards education and awareness raising of conservation issues. Nevertheless, the non-charismatics are equally deserving of attention, and more work needs to be done on their welfare."

"The extinction of the Australian Megafauna was probably the first significant mark Homo sapiens left on our planet."

"At the time of the Cognitive Revolution, the planet was home to about 200 genera of large terrestrial mammals weighing over fifty kilograms. At the time of the Agricultural Revolution, only about one hundred remained. Homo sapiens drove to extinction about half of the planet's big beasts long before humans invented the wheel, writing or iron tools."
