  1. Molecular studies of the guenons suggest that the arboreal Cercopithecus species form a monophyletic group within the tribe Cercopithecini. However, the evolutionary relationships among these arboreal congeners remain poorly resolved. The present…
  2. In mammals, flies, and worms, sex is determined by distinctive regulatory mechanisms that cause males (XO or XY) and females (XX) to differ in their dose of X chromosomes. In each species, an essential X chromosome-wide process called dosage…
  3. BACKGROUND: Due to its history, with a high number of migration events, the Mediterranean basin represents a challenging area for population genetic studies. A large number of genetic studies have been carried out in the Mediterranean area using…
  4. A collection of subfossil wood of Pinus sylvestris (Scots pine) was exposed to X-ray densitometry. The collection of 64 samples from the southern boreal forest zone was dendrochronologically cross-dated to A.D. 673-1788. Growth characteristics were…
  5. To test the assumption that different earthworm species make differently-structured burrow systems that can affect water permeability, the burrow systems made by adults of three earthworms species (Lumbricus terrestris, Nicodrilus giardi and…
  6. Existem poucos estudos abordando a biodiversidade fitoplanctônica em ambientes aquáticos de planície de inundação, o que sugere a necessidade de estudos taxonômicos visando à conservação e recuperação desses ecossistemas. A Classe Xanthophyceae foi…
  7. Photosynthetic activity, pigment conversion and D1 protein degradation under high light stress has been investigated in a wild type strain and two xanthophyll cycle mutants (npq1 and npq2) of Chlamydomonas reinhardtii. Wild type cells exhibited the…
  8. The electronic transitions of lutein and neoxanthin in the major light-harvesting complex, LHCIIb, have been identified for the first time. It was found that 0-0, 0-1 and 0-2 transitions of neoxanthin were located around 486, 457 and 430 nm, whilst…
  9. Contentious issues in Night Lizard (Xantusiidae) evolution are revisited using Maximum Likelihood-based Bayesian methods and compared with results from Neighbor-Joining and Maximum Parsimony analyses. Fragments of three mitochondrial genes, the 12S…
  10. Metabolite profiling in biomarker discovery, enzyme substrate assignment, drug activity/specificity determination, and basic metabolic research requires new data preprocessing approaches to correlate specific metabolites to their biological origin.…
  11. On 11 March 2011, an earthquake occurred about 130km off the Pacific coast of Japans main island Honshu, followed by a large tsunami. The resulting loss of elec- tric power at the Fukushima Dai-ichi nuclear power plant (FD-NPP) developed into a 5…
  12. Ecological niche models (ENMs) provide a means of characterizing the spatial distribution of suitable conditions for species, and have recently been applied to the challenge of locating potential distributional areas at the Last Glacial Maximum…
