In the present study, Randomly Amplified Polymorphic DNA (RAPD) markers were used to analyze the genetic diversity in 20 varieties of Philodendron. The polymerase chain reaction was performed with 60 RAPD primers, out of which 21 primers showed clear amplification as well as more polymorphism. In total, 354 scorable RAPD loci with 348 polymorphic bands (98%) were observed. Percentages of polymo...

X-band electron-paramagnetic-resonance spectroscopy at 4.2--77K combined with measurements of oxidation-reduction potential was used to identify iron--sulphur centres in Arum maculatum (cuckoo-pint) mitochondria. In the oxidized state a signal with a derivative maximum at g = 2.02 was assigned to succinate dehydrogenase centre S-3. Unreduced particles showed additional signals at g = 2.04 and 1...

We undertook a survey of mammal diversity and indigenous knowledge of mammals in Hewa country, in the vicinity of Wanakipa village, Southern Highlands Province, during July 2008. Specimens collected during this survey document the occurrence of 22 mammal species in the immediate area, including one monotreme, 6 marsupials, 7 rodents, and 8 bats. Two species of conservation concern, the Eastern ...

This is the first revision in more than 100 years of African genus Pseudohydrosme , formerly considered endemic to Gabon. Closely related Anchomanes distinct from because its 2-3-locular ovary (vs. unilocular), peduncle concealed by cataphylls at anthesis and far shorter spathe exposed, exceeding spathe), stipitate fruits viviparous (asexually reproductive) roots sessile, non-viviparous), lack ...
