13 The background of ecology 生態觀 (一) 「自然平衡」
西元前 4th世紀： 自然平衡/神意的(providential)生態學 Aristotle：田鼠的高生殖率，可產生更多田鼠，受其天敵減少數量，如：狐狸、 白鼬、人的控制、大雨。 Herodotus and Plato：自然被設計成保育每一種生物。每一種生物於自然中都有其特定的位置；絕種並未發生, 因若發生將破壞大自然的平衡與和諧。

14 The background of ecology 生態觀 (二) 「自然和諧」
17th - 19th 世紀：自然和諧 Graunt (1662) 人口數學化，以出生率，死亡率，性別比年齡結構，預測倫敦人口於64年間加倍。 Leeuweenhoek (1687) 計算母蒼蠅產下的卵數，估 計一對蒼蠅三個月內可產生746,496個蒼蠅。 Buffon (1756) Natural History 族群調控 / 疾病， 食物不足 Malthus (1798) Essay on Population. 生殖終要受 食物的生產量的限制 (checked)

15 The background of ecology 生態觀 (三) 達爾文的「演化論」
Farr (1834): Malthus 推測食物生產量以等差級數增加，這並不真實，至少在美國，食物生產量是以等比級數增加，甚至比人口成長更快。 20th 世紀: 「天擇」與「為生存奮鬥」, 逐漸取代「自然平衡與神意的」生態學。 於1900年前， Ecology 逐漸成為「科學」 根源於：自然史、人口學、生物統計學、 農業和醫學(公共衛生、傳染病)之應用。

16 大眾覺醒 (Public awakens)(一)
雖然應用生態學早在1930年代興起，但要一直到1970年代，才因大眾的關注而逐漸受重視。 A. Bramwell (1989) 稱: 1970年代的環保和生態運動是 Ecologism (生態主義) (生態主張) 「人和環境」的研究，追溯至1800年代。

17 「人和環境」的研究 (一) G. P. Marsh (1864): Man and Nature.
E. Haeckel (1900): The Riddle of the universe. (1905): The wonders of Life. / back-to-the-land movement / 有機農業/土壤和森林保育 J. Ritchie (1920): The influence of man on animal life in Scotland.

20 環保重要里程碑(一) 1605 英國東海岸沼澤濕地開發計劃, 被 Fenmen 阻止。

21 環保重要里程碑(二) (1960s) 1964 野地法案(Wilderness Act) 簽定。
1966 endangered species act passed. 1967 美國 International Biological Program (IBP) 研究生態体系: 凍原, 針葉林, 落葉林, 沙漠, ... 目標: (1) 瞭解生態体系內的各種因素間的互動。 (2) 研析增加生物的生產力。 (3) 增進預測影響的能力。 (4) 增進經營自然資源的能力。 (5) 增進對人類基因, 生理和行為適應的知識。

22 環保重要里程碑(三) (1970s-90s) 1970 國家環境政策(NEPA) 和清淨空氣法案立法。
1970 第一次「地球日」(Earth day) 1970 UNESCO 的 Man and the Biosphere Program. 1980 IUCN 發行 World Conservation Strategy.(世界保育策略) 1983 核子戰爭的長期全球生物影響研討會 1992 聯合國的環境與發展的國際大會於巴西舉行。(里約) 2000 International Biodiversity Observation Year 2001 全球綠盟大會 2002 可持續發展的世界高峰會議

23 A Year for Biodiversity
(『生物龐雜度』之年) (2000) BioScience 內容：『國際生物龐雜度關注之年』(International Biodiversity Observation Year，簡稱 IBOY)將聯合 相關『生物龐雜度』科學的進展，且提升其在決 策和大眾心目中的地位。這項計畫已經得到 『DIVERSITAS』的贊助。『DIVERSITAS』是一 個國際科學團體，致力於從基因至生態體系各個 生物層面的龐雜度之研究。

24 The problem of identity (本體的問題)
To survive and grow, a discipline requires a unique conceptual framework (獨特的觀念架構) and a set of identifiable intellectual distinctions that can be shared by a professional community with a common mission. Michael Soule, one of the founders of conservation biology, said, “disciplines are not logical constructs; they are social crystallizations which occur when a group of people agree that association and discourse serve their interests. Conservation biology began when a critical mass of people agreed that they were conservation biologists” (Soule, 1986).

25 Conservation biology 的界定
As the science of scarcity and abundance (稀有和豐富) As “application of biology to the care and protection of plants and animals to prevent their loss or waste” (Meffe and Carroll, 1997) On the preservation of biodiversity (the entire range of all species).

26 四項基本假定 Diversity of organisms is good Ecological complexity is good
Humans seem to inherently enjoy diversity of life forms (called biophilia by E. O. Wilson, 1984). Ecological complexity is good Evolution is good. Biotic diversity has intrinsic value, regardless of its utilitarian value.

27 Conservation ethics (保育倫理)
Dyke, F. V. (2003) Conservation Biology. McGraw-Hill Inc. All living creatures possess intrinsic value (內在價值). The physical environment and the living organisms in natural ecosystem perform vital services and produce goods essential to the continuance of human civilizations (人類文明的持續). Further, the species within the ecosystems are vital for maintaining their function and structure. The physical environment and its creatures add value, knowledge and meaning (價值，知識和意義) to the experience of being human and to the appreciation of higher values and virtues.

28 Conservation biology 的特質
Both value laden (負有價值取向) and mission driven (任務導向). Advocacy oriented (倡導取向) A crisis-oriented (危機取向) discipline Integrative and multidisciplinary nature Concerned with evolutionary time (genetic heritage) Adaptive science, with a higher degree of uncertainty (不確定性). A legally empowered science.

30 保育生物學者研究的主題 The conservation of genetic diversity
The conservation of species The conservation of habitat The management of landscapes (地景的經營) through ecosystem processes Sustainable development (可持續發展) of human economies and human populations. (經濟和人口)

31 1. The conservation of genetic diversity
Inbreeding depression Genetic drift (基因飄移) Fixation of harmful alleles Hybridization and introgression

32 2. The conservation of species
Minimum viable population (MVP) Population viability analysis (PVA) Small-population paradigm Declining population paradigm Metapopulation theory

33 3. The conservation of habitat
Habitat loss, habitat fragmentation, habitat isolation The theory of island biogeography (島嶼生物地理學) Habitat heterogeneity Restoration ecology (復育生態學)

34 4. The management of landscape through ecosystem processes
Ecosystem management (生態體系的經營) Any land management system that seeks to protect viable populations of all native species, perpetuates natural disturbance regimes on the regional scale, adopts a planning timeline of centuries, and allows human use at levels that do not result in long-term ecological degradation. (Noss and Cooperrider, 1994) Integrates scientific knowledge of ecological relationships within a complex sociopolitical and values framework toward the general goal of protecting native ecosystem integrity over the long term (Grumbine, 1994)

35 5. Sustainable development of human economies and human populations
雖然保育生物學源自於生物學和生態學，傳統上關注於「非人類世界」，但是conservation biology must address problems of economic development and the growth of human populations.

37 Chapter 1 What is conservation biology?
Expanding human demands on Earth 人口數量 (Fig. 1.1, 1.2) 平均每人的消費量 (Fig. 1.3) Human footprint (足跡) (Fig. 1.4) Stewardship (領導地位) of natural biodiversity Requires a strong link be forged between conservation biology and environmentally sustainable development. Responding to Global change Conservation biology as a “crisis discipline”

40 10萬年來，人類平均每人每年消耗的能量。原始時期~10萬年前；狩獵-採集 ~1萬年前至10萬年前；早期農業~7,000 年前至1萬年前；文明興起：~1400AD；工業時代~1875AD；科技時代~1950AD。

41 科技讓我們可以享受得更多。但問題是資源的再生來源(太陽)並沒有增加。
Wackernagel, M. (1996) Our ecological footprint: reducing human impact on the Earth. 過去 現代 科技讓我們可以享受得更多。但問題是資源的再生來源(太陽)並沒有增加。

42 現代的科技不僅可挖掘出更多的資源，同時也造成許多的滲漏與浪費，且更是產生許多污染。

46 Guiding principles for CB
Evolution is the basic axiom that unites all of biology (The evolutionary play) The ecological world is dynamic and largely nonequilibrial (the ecological theater) Human presence must be included in conservation planning (Humans are part of the play)
