Abstract:
Charles Darwin has achieved both notoriety and fame for his evolutionary ideas encapsulated principally in The Origin of Species and The Descent of Man. Although credited for much originality in his writings, Darwin's legacy borrowed extensively from many who had propounded similar speculations centuries before him. His naturalistic argument for origin and species reveals both logical and theological problems with his thesis, and further unavoidable ramifications. The contention is that even Darwin himself could not, and did not, live by the ideas he boldly espoused. His ideas, if true, would

Abstract:
The worlds of Dickens's novels and of Darwin's science reveal striking similarity in spite of their involvement in different areas. The similarity comes from the fact that they shared the ethos of Victorian society: laissez-faire capitalism. In The Origin of Species, which was published on 1859, Charles Darwin theorizes that nature has evolved through the rules of natural selection, survival of the fittest, and the struggle for existence. Although his conclusion comes from the scientific evidence that was acquired from his five-year voyage, it is clear that Dawinian nature is reflected in crue

Inorganic arsenic is a toxic element known to cause various diseases and cancers in humans.

Abstract:
碩士<br>國立臺灣大學<br>生態學與演化生物學研究所<br>101<br>Adiantum meishanianum is an endemic species distributed only in Meishan village, Kaohsiung, Taiwan. Adiantum meishanianum has been regarded as a hybrid origin. Previous studies suggest that A. caudatum, A.malesianum and A. philippense are its putative parents. Its sporangium contains only abortive spores implying its triploidy. The aim of the study is therefore to determine the hybrid origin of A. meishanianum by examining cytological status, reproductive strategy and reconstructed molecular phylogeny among these species. In A. caudautum we identified dip

Abstract:
This thesis describes our current knowledge on the taxonomy and archaeology of some Asian, African and Australasian Canis and explores new approaches to their classification and identity, using the Asian pariah as a pivotal point. I analysed several populations of primitive dogs, and described processes of diversification. What in many places is simply designated "the village dog" is a subtype of the pariah; the Australian dingo is also connected to the pariah, although there are some peculiarities related to its non-domestic nature; and I propose a hypothesis on the nature of the pariah.

Abstract:
Endophytes are organisms that live inside plants without causing disease and include microbes that benefit their hosts by aiding in nutrient acquisition and pathogen control. This thesis concerns the endophytes of the genus Zea which includes modern maize (Zea mays L.). Beginning 9,000 years ago, maize was domesticated from wild grasses in Mexico (teosintes), bred into diverse varieties and moved to new soils throughout the Americas. The impact of these long-term changes on the associated endophytic communities has not been examined. Furthermore, today, maize is routinely transplanted around t

Abstract:
In the present thesis, using midges (Diptera Chironomidae) as flagship taxa of freshwater ecology, I am focusing on the interesting research model represented by the Skadar Lake system. It is a well-known hot-spot of freshwater biodiversity consisting of the geologically young lake Skadar (originated ca. 1200 years BP) and by its ancient system of springs (originated in the Pliocene). The main aim of my thesis was to reveal and compare the morphological and molecular species diversity of non-biting midges (Diptera, Chironomidae) inhabiting Skadar Lake and its spring system.

In Taiwan, Rhododendron species are found from the lowlands to the highest mountain. But Taiwanese Rhododendron species, which are only finding in middle to high elevation, contain four species. These four Taiwanese Rhododendron species include R.hyperythrum、R.rubropanctatum、R.morii and R.pseudochrysanthum. In these species, taxonomists classified them as a single species (R.pseudochrysanthum) by morphological way (Flora of Taiwan ver.4). In fact, there is only a 0.4% ge

Abstract:
The origin and geographical distribution of mammalian species (my examples are lemurs and bats) correlate with predictable chromosomal structural changes (KFT=karyotypic fission theory). Chromosome studies provide information about fertility between individuals and they are significant for identification of the geographical origin of reproductive isolation within mammal families. Each family predictably has chromosome sets with numbers that range from one to double the lowest number of chromosomes. The chromosome numbers of all species within a single family are used to reconstruct that family
