Emperor Penguin (Young Zoologist): A First Field Guide to the Flightless Bird from Antarctica

為了解決Zoologist Panda的問題，作者Larue, Michelle,Neon Squid 這樣論述：

Up close and personal with the world’s largest penguin... Informative and winning. -- KirkusTake to the Antarctic ice to study emperor penguins in this beautiful nonfiction field guide for kids.You might know that emperor penguins are the largest penguin species, but there’s so much more to learn

about this flightless bird. Turn the pages to discover what makes them undertake epic journeys every year, and how scientists have spotted their poop from space! Filled with simple science and plenty of animal facts, this book also explains what makes emperor penguins such great ocean swimmers, and

how their cute chicks manage to stay warm in freezing Antarctic conditions. It also looks at the conservation challenges these iconic animals face due to climate change and melting sea ice. Written by penguin professor Dr. Michelle LaRue and featuring stunning illustrations by Pham Quang Phuc, Empe

ror Penguin (Young Zoologist) is part of an exciting new series of animal books from Neon Squid aiming to inspire the next generation of biologists and conservationists. Also available: Humpback Whale, Giant Panda, African Elephant

Reproductive Physiology of Taiwanese Pangolin (Manis pentadactyla pentadactyla)

為了解決Zoologist Panda的問題，作者Bharti Arora 這樣論述：

Taiwanese pangolin (Manis pentadactyla pentadactyla) knowledge of reproductive physiology is imperative to maintaining a healthy ex-situ and in-situ population. Pangolins have been exhibited in zoos since the mid-1800s, but these prolonged years of captivity are facing a dilemma to propagate succes

sful breeding in captivity. According to International Studbook and Formosan pangolin PHVA final report, this species' gestation length is confined in skepticism as well as has a low reproductive rate. Moreover, loss of neonates to stillbirths and incorrect maternal care during the critical period o

f pregnancies in captivity. As females do not exhibit clear signs of estrus or any specific sexual behavior and sometimes the signs of pregnancy have not been recognized to facilitate association between males and females to generate good breeding conditions. Pangolins have captivated the attention

to unravel ecological and behavioral parameters, but reports on reproductive endocrinology are sketchy. I studied various reproductive physiology parameters (mating, pregnancy, gestation, and parturition) using serum and fecal samples procured from longitudinal sampling.Fecal samples obtained enable

d me to devise various metabolic forms of adrenal and gonadal steroids with the establishment of a pivotal study using the technique of Electrospray Mass Spectrometry (ESI-MS) existing in these endangered species of pangolins. The study also helped me unveil that Taiwanese pangolin does not show any

significant differences among the functional categories of sub-adult (SA) and adult (A) in both males and females. However, the males showed significantly high differences in the level of fecal glucocorticoids compared with females.The long-term hormonal examination of serum samples of pangolins fr

om captivity illustrated significant differences in serum estradiol concentration between non-pregnant and pregnant females. However, both groups showed that estradiol's peak is synonymous with the annual mating season tied during the end of the year (November to January). The rising levels of proge

sterone in non-pregnant individuals during January suggest that estradiol and progesterone help in ovulation and estrus behavior in females. In pregnant females, the progesterone concentration sustained from January to September and drastically declined to mark the phase of parturition (October-Dece

mber) in this species. In contrast, the non-pregnant females illustrated baseline concentration of serological progesterone apart from the estrus phase as marked in other closely related carnivores. This long gestation period of ~275 days (January-September) witnessed in pregnant females that it is

highly probable that pangolins exhibit delayed implantation phenomena. The prolactin studies explained that pangolins exhibit a brief period of diapause because of the nursing behavior, which lasts from December to May.Interestingly, males showed a seasonal pattern of testosterone levels. The endocr

inological results suggest that the males engage in the mating behavior when the testosterone levels are the highest (October) in synchrony with females' parturition behavior. In summary, the hormonal evidence found both in male and female Taiwanese pangolin suggests that pangolins are seasonal bree

ders. This study also provided needed information on endocrinology and reproductive physiology for a hitherto unstudied species and provided a basis for a crucial contribution to future reproductive measures in conserving this enigmatic mammal.

Giant Panda (Young Zoologist): A First Field Guide to the Bamboo-Loving Bear from China

為了解決Zoologist Panda的問題，作者Neon Squid,Hull, Vanessa 這樣論述：

Vanessa Hull was five years old when she was given a stuffed panda toy, which ignited a lifelong passion. Today she is an Assistant Professor at the University of Florida and has spent her career studying giant pandas in the forests of China.Charlotte Molas is a French illustrator who splits her tim

e between Paris and Biarritz. Her colorful illustrations are inspired by Matisse, the Art Déco movement, and pop culture. She spends her time working on books and magazines, and putting on exhibitions of her work. Her name is pronounced ＂Mola＂ without the s, and it means You rock in Spanish.

圈養台灣黑熊幼獸行為發展及親子關係

為了解決Zoologist Panda的問題，作者林依蓉 這樣論述：

台灣黑熊（Ursus thibetanus formosanus）為晚熟型物種，親代照顧對於幼熊的生長發育及行為發展有重要影響。本研究旨在瞭解圈養台灣黑熊母子於幼熊1歲之前的幼熊成長發育，以及親子行為隨年齡的變化。本研究針對1對壽山動物園及2對特有生物保育研究中心的黑熊親子，利用監視數位錄影系統與現場觀察的方式記錄24小時行為模式，共取樣145天。 幼熊於1月齡眼睛張開，1.5至2月齡能爬行，2月齡之後可以行走，母熊在2月齡之前亦較少離巢，親子日活動程度在2月齡之前均最低，之後逐漸上升。在幼熊1歲之前，不活動與遊戲佔親子一天時間比例的最多與次之，在母熊分別是77.7%與5.7%，幼熊的

不活動與遊戲則是67.3%與13.6%。親子以日行性為主，但晨昏時段活動稍高，母熊日、夜間活動比例分別為37.6%與8.6%，幼熊日、夜間活動比例53.2%與14.2%。親子身體接觸的互動比例在5-6月齡之前均高50%，由此可看出在5-6月齡之前親子間關係似乎較親密。 1歲齡之前親子平均每天哺乳次數8.8（±2.7）次，每天哺乳時間42.9（±11.3）分鐘。親子每天哺乳次數與總時間呈現前（＜4月齡）、後期（9-12月齡）高，中間期（5-8月齡）偏低的趨勢。後期哺乳時間與次數較中期高，推測受飼糧所限，幼熊轉向母熊索取能量來源—乳汁、食物—的機會隨之增加，如此也引發了親子之間的衝突，因為進

食而引發的親子敵對行為，以及母熊對幼熊索奶的敵對反應，均隨幼熊年齡而有增加的趨勢。單胎、雙胎的每天哺乳次數與時間並沒有顯著差異，然雙胎的遊戲或與其他熊遊戲的日出現頻度（20.1%，15%）皆較單胎高（17.3%，9.6%）；雙胎幼熊相互遊戲的頻度（7.7%），明顯高於幼熊與母熊之間遊戲（2.2%）。雙胎親子間的身體接觸顯著高於單胎（64.4% vs. 49.7%），單胎親子的無互動佔47.8%顯著高於雙胞胎的19.3%，可看出雙胎親子關係較單胎親子密切。 圈養黑熊親子對於其他成熊叫聲的反應程度與吼叫音量皆有顯著正相關，顯示面對潛在威脅壓力時，親子會出現不同程度防禦或躲避的本能反應。黑熊親

子於於飼糧供給量較多、環境大且豐富的親子，進食時間比例較高，期待餵食及母熊刻板行為的時間比例均較低。於24小時活動模式上，親子上、下午均各有一活動高峰，但在圈養環境豐富、空間較大且無門禁的個體，上午活動高峰較早出現。本研究顯示黑熊親子行為及互動受圈養環境及管理方式影響。
