Seychelles

為了解決Polar region animals的問題,作者Mair, Lyn,Beckley, Lynnath 這樣論述:

This new sixth edition of Bradt's Seychelles has been fully updated and remains the only travel guide giving comprehensive information on the biodiversity of the islands and updates on the conservation efforts in an easy to read format (over 40% of the Seychelles land is under environmental protecti

on). New for this edition are expanded details of the many accommodation options, from F licit Island's luxurious resort and the many hotels recently refurbished to higher standards to the growing number of B&Bs and small guest houses that offer a more authentic Seychellois experience. New destinat

ion-specific places covered include the Outer Islands of Alphonse, Astove and Cosmoledo, and new practical information includes all the latest updates on getting around plus the significant increase in Marine Protected Areas.With plants and animals historically linked to Africa, Madagascar and Asia,

and marine life native to the tropical Indo-Pacific region, the Seychelles is a haven for those interested in natural history. The authors provide fascinating coverage of the islands' fauna and flora, from mangroves and turtles to birds and nature reserves. Updated throughout, they reveal the islan

ds many secrets from coco de mer palm forests and bird sanctuaries to local markets and Creole cuisine. This new edition not only provides up-to-date details of where to stay, eat and relax, but also where the to find the world's tiniest tree frog and how to visit Bird Islands to see the world's hea

viest Giant Tortoise.Beaches, snorkelling and diving among the coral reefs, wildlife, sailing, festivals, the UNESCO World Heritage Site of Vallee de Mai and hiking in the mountains... all are covered in Bradt's Seychelles, making it an ideal companion for a dream holiday. Lyn Mair is a naturalist

and travel guide who specializes in the islands of the western Indian Ocean, West Africa and Antarctica. Passionate about birdwatching, she regularly leads tours to exotic places and lectures on board ships plying the tropical waters off Africa and Polar regions. She was one of the first volunteers

to undertake environmental monitoring on Aldabra and has also spent many months travelling around the islands. Since her first visit in 1995 she has set foot on many of the most remote islands in the Seychelles.Lynnath Beckley is a professor of marine science at Murdoch University, Perth, Western A

ustralia and specialises in the Indian Ocean. She has undertaken scientific research, travelled and sailed extensively in the western Indian Ocean and has been writing for magazines, journals and books for many years.

探討台灣特有種台灣鉤嘴鹛近期適應的遺傳基礎

為了解決Polar region animals的問題,作者傅雨辰 這樣論述:

適應是指族群中的變異性狀受到選擇,因而提升生物生存概率和繁殖能力的過程。表型性狀變異的遺傳來源包括三種不同類型:新突變、既有變異、與漸滲。然而,它們在基因組中組成佔比如何,及對物種適應產生的相對貢獻仍然不為人知。本研究中,我以廣泛分佈于中國大陸南部、東南部、東部和海南島的棕頸鉤嘴鹛(Pomatorhinus ruficollis, Timaliidae, Aves)和它在台灣島的姐妹種,特有種台灣鉤嘴鹛(Pomatorhinus musicus)作為評估不同遺傳變異對近期適應相對貢獻的生物系統。為了評估台灣鉤嘴鹛的適應性遺傳變異的組成和來源,首先組裝了棕頸鉤嘴鹛高質量的染色體水平參考基因組。

接著,我將台灣鉤嘴鹛基因組內遺傳變異分為三類:兩種鉤嘴鹛分化以來出現的新突變(5,431,390个SNPs,占總基因组SNPs的8. 87%),保持在台灣鉤嘴鹛內的既有變異(55,769,269个SNPs,占總基因组SNPs的91.04%),以及從棕頸鉤嘴鹛漸滲引入的變異(59,126个ABBA-BABA计数的SNPs,占總基因组SNPs的0.096%)。然後,我使用nSL test檢測台灣鉤嘴鹛支系中受到近期正向選擇的基因組區域。在受到正向選擇的基因組區域內,既有變異是台灣鉤嘴鹛近期適應的主要遺傳來源(642,823个SNPs,占既有變異總數的1.15%)。從棕頸鉤嘴鹛而來的漸滲基因占全部基

因組的0.096%,漸滲基因中沒有顯著受到高比例的正向選擇(79個基因中有2個受到正向選擇)。儘管漸滲基因對台灣鉤嘴鹛基因組貢獻不大,但這些與生物基礎功能相關的基因可能仍對物種適應有重要作用。

Into the White: The Renaissance Arctic and the End of the Image

為了解決Polar region animals的問題,作者Heuer, Christopher P. 這樣論述:

How the far North offered a different kind of terra incognitafor the Renaissance imagination.European narratives of the Atlantic New World tell stories of people and things: strange flora, wondrous animals, sun-drenched populations for Europeans to mythologize or exploit. Yet, as Christopher Heuer e

xplains, between 1500 and 1700, one region upended all of these conventions in travel writing, science, and, most unexpectedly, art: the Arctic. Icy, unpopulated, visually and temporally "abstract," the far North--a different kind of terra incognita for the Renaissance imagination--offered more than

new stuff to be mapped, plundered, or even seen. Neither a continent, an ocean, nor a meteorological circumstance, the Arctic forced visitorsfrom England, the Netherlands, Germany, and Italy, to grapple with what we would now call a "non-site," spurring dozens of previously unknown works, objects,

and texts--and this all in an intellectual and political milieu crackling with Reformation debates over art's very legitimacy. In Into the White, Heuer uses five case studies to probe how the early modern Arctic (as site, myth, and ecology) affected contemporary debates over perception and matter, r

epresentation, discovery, and the time of the earth--long before the nineteenth century Romanticized the polar landscape. In the far North, he argues, the Renaissance exotic became something far stranger than the marvelous or the curious, something darkly material and impossible to be mastered, some

thing beyond the idea of image itself.

核能電廠鄰近水域與淡水河河口區的浮游動物群聚與死亡率研究

為了解決Polar region animals的問題,作者李佩玟 這樣論述:

核能發電廠大量排放溫排水,其溫排水影響核電廠周圍水文環境,因此核能發電廠之溫排放水對環境的影響是全球保育工作所關注的議題之一。本論文於臺灣北部兩個核電廠之入、出水口採集浮游動物;採樣季節間紀錄浮游動物於不同月份間的組成變化,發現主要優勢大類為橈足類。核二廠浮游動物豐度顯著高於核一廠( p = 0.001),而橈足類及全體浮游動物大類之豐度於西南季風期間也顯著高於東北季風期。本研究在核電廠測站使用中性紅(Neutral Red)染色法來鑑別浮游動物之存活狀態。發現出水口死亡率明顯高於入水站(p < 0.01)。在核一廠之結果顯示多數浮游動物類群和所有浮游動物群落的死亡率與出入水口的水溫溫差(Δ

T)呈現顯著正相關(p < 0.05);核二廠之浮游動物群落死亡率與水溫溫差(ΔT)亦為正相關但是不顯著(p > 0.05)。於兩個核電廠間的浮游動物碎片無灰乾重分析比較,發現出水口測站之浮游動物碎片有機質重量顯著高於入水口站,顯示浮游動物的軀體在通過核電廠冷卻系統時受到機械性之物理破壞。淡水河為臺灣第三大河流,同時是北部最大之潮汐河流,河流流域包含首都臺北市,該地區居住約600萬人,受到上游淡水及河道兩旁工廠及家庭所排放廢水產生交互影響,同時亦受到中國沿岸流及黑潮所影響。本研究於淡水河出海口及下游河段進行表層拖網,每兩個月進行一次浮游動物採集,主要紀錄浮游動物不同月份間之豐度及組成變化。本論

文於淡水河下游及河口區紀錄浮游動物為14種,主要優勢種為十足目、橈足類(哲水蚤、劍水蚤及猛水蚤)和其他幼體。橈足類豐度變化與鹽度、溫度、pH及溶氧等環境因子顯著相關;集群分析結果顯示橈足類具有幾種不同組成之群聚,群聚間均有喜好之水文條件,而橈足類部分於採樣測站及月份間具有顯著差異。本論文同時首次彙整及探討臺灣主要河域之橈足類,並且與國外河域之橈足類的生物多樣性做比較。本論文首次揭露與探討淡水河口及下游地區浮游動物及橈足類之死亡率與滲透壓改變對死亡率之影響,浮游動物粗分為四大類(橈足類、甲殼類、軟體動物及其他浮游動物),使用中性紅染色法研究各測站內死亡率之差異,取得第一階段實驗結果後即更深入探討

浮游動物死亡率與鹽度變化之關係。結果顯示浮游動物死亡率隨著鹽度如淡水至天然海水間的梯度般變化時,死亡率與之呈現顯著的負相關;當鹽度降低即死亡率顯著增加,透過統計分析找出河口水域自然環境之浮游動物的半致死鹽度。
