Acidophilic Collembola: living fossils?
The existence of two groups of acidophilic (mostly present in soils at pH less than 5) and acidintolerant Collembolan species has been demonstrated concurrently by several authors in the course of biocoenotic studies. The examination of morphological features points to a strong relationship between acidophily and hypothetical phyletic relationships between both groups. In the light of Earth his...
متن کاملCoelacanths as “almost living fossils”
*Correspondence: Lionel Cavin, Département de Géologie et Paléontologie, Muséum d’Histoire Naturelle, 1 rue Malagnou, CP6434, 1211 Genève 6, Switzerland e-mail: [email protected] Since its usage by Darwin (1859), the concept of “living fossil” has undergone multiple definitions and has been much discussed and criticized. Soon after its discovery in 1938, the coelacanth Latimeria was rega...
متن کاملIn living context: an interdisciplinary approach to rethinking rural prevention.
This chapter argues that knowledge of two factors—local context and latest teaching and learning models—is crucial in the successful dissemi-nation of national school-based drug and alcohol prevention programs for young people in rural areas. Successful dissemination is defined as programs that achieve their intended goals (i.e., delaying the onset of alcohol and other drug (AOD) use and abuse ...
متن کاملRethinking EU Trade Procedures - The Beer Living Lab
The EU is currently reshaping its customs legislation and practices. Main pillars in the new vision are an intensive use of IT (Customs becomes e-Customs), partnerships between Customs administrations and businesses, and collaboration between national Customs administrations. These concepts should support coping with the dilemma of on the one hand increasing security, safety, financial and heal...
متن کاملWhy coelacanths are not 'living fossils': a review of molecular and morphological data.
A series of recent studies on extant coelacanths has emphasised the slow rate of molecular and morphological evolution in these species. These studies were based on the assumption that a coelacanth is a 'living fossil' that has shown little morphological change since the Devonian, and they proposed a causal link between low molecular evolutionary rate and morphological stasis. Here, we have exa...
