Detection Of Panax Quinquefolius In Panax Ginseng Using ‘Subtracted Diversity Array’, Linhai Niu, Nitin Mantri, Chun Li, Charlie Xue, Hans Wohlmuth, Edwin Pang

Dr Hans Wohlmuth

BACKGROUND: Food adulteration remains a major global concern. DNA fingerprinting has several advantages over chemical and morphological identification techniques. DNA microarray-based fingerprinting techniques have not been used previously to detect adulteration involving dried commercial samples of closely related species. Here we report amplification of low-level DNA obtained from dried commercial ginseng samples using the Qiagen™ REPLI-g® Kit. Further, we used a subtracted diversity array (SDA) to fingerprint the two ginseng species, Panax ginseng and Panax quinquefolius, that are frequently mixed for adulteration. RESULTS: The two ginseng species were successfully discriminated using SDA. Further, SDA was sensitive enough to detect a …

Adaptation As Process: The Future Of Darwinism And The Legacy Of Theodosius Dobzhansky, David Depew

David J Depew

Conceptions of adaptation have varied in the history of genetic Darwinism depending on whether what is taken to be focal is the process of adaptation, adapted states of populations, or discrete adaptations in individual organisms. I argue that Theodosius Dobzhansky’s view of adaptation as a dynamical process contrasts with so-called “adaptationist” views of natural selection figured as “design-without-a-designer” of relatively discrete, enumerable adaptations. Correlated with these respectively process and product oriented approaches to adaptive natural selection are divergent pictures of organisms themselves as developmental wholes or as “bundles” of adaptations. While even process versions of genetical Darwinism are insufficiently sensitive …

The Complexity Of Amphibian Population Declines: Understanding The Role Of Cofactors In Driving Amphibian Losses, Andrew Blaustein, Barbara Han, Rick Relyea, Pieter Johnson, Julia Buck, Stephanie Gervasi, Lee Kats

Lee Kats

Population losses and extinctions of species are occurring at unprecedented rates, as exemplified by declines and extinctions of amphibians worldwide. However, studies of amphibian population declines generally do not address the complexity of the phenomenon or its implications for ecological communities, focusing instead on single factors affecting particular amphibian species. We argue that the causes for amphibian population declines are complex; may differ among species, populations, and life stages within a population; and are context dependent with multiple stressors interacting to drive declines. Because amphibians are key components of communities, we emphasize the importance of investigating amphibian declines at the …

Description Of The Tadpoles Of Hypsiboas Aguilari And H. Melanopleura Aguilari And H. Melanopleura (Anura: Hylidae: Hypsiboas Pulchellus Group), Edgar Lehr, Julian Faivovich, Karl-Heinz Jungfer

Edgar Lehr

We describe the tadpoles of Hypsiboas melanopleura and H. aguilari and compare them with the tadpoles of other species in the Hypsiboas pulchellus group. The description of the tadpole of H. aguilari is based on an individual at Gosner Stage 29 and that of H. melanopleura on an individual at Gosner Stage 28. Both tadpoles have a labial tooth row formula of 2(2)/4(1). At Stage 35, the tadpole of H. aguilari had a total length of 52.2 mm, at Stage 37, the tadpole of H. melanopleura had a total length of 60.7 mm. In life, the tadpole of H. aguilari …

The New Atheists' Narrow World-View, Stephen Asma

Stephen T Asma

The article discusses atheism, Buddhism, and the practice of animism in southeast Asia. Atheists such as Christopher Hitchens and Sam Harris are discussed as is the argument regarding the "provincialism" of religion. It is noted that some atheists echo the statement by philosopher Karl Marx that religion is an opiate that should be done away with because it has little moral value. The use of spirit houses as a part of religious practice in southeast Asia is described. The opinion held by theists on animism is explored. Other topics include living conditions in Cambodia and the role of religion in …

Can Culture Shape The Identity Of A Sport? A Case Study On Lifesaving Sport - Surf Lifesaving Australia And Lifesaving/Sauvetage Canada, Winston Wing Hong To

Winston Wing Hong To

Sport is an important marker of our country's culture and identity. Citizens within a country will cheer and support their sport teams if they are successful, or criticize and judge if they are doing poorly. The importance of culture within sport is an important indicator of a country's success or failure within international competitions; such as the Olympics and World Championships. However, can culture shape the identity of a sport within a country?

Lifesaving is a vital aspect of a country's swim program, as it focuses on reducing injury and death in, on, or around the water. Within Lifesaving, there …
