molecular and morphological characterization of an unusual meloidogyne arenaria population from traveler's tree, ravenala unusual variant of meloidogyne arenaria was discovered on roots of a traveler's tree (ravenala madagascariensis) intended for display at a public arboretum in pennsylvania. the population aroused curiosity by the lack of visible galling on the roots of the infected plant, and the female vulval region was typically surrounded by egg sacs. most morphometrics of the population fit within the ranges reported for m. arenaria, with a mosaic of features in common with either m. platani or other trop ...200819440257
alcohol discrimination and preferences in two species of nectar-feeding primate.recent reports suggest that dietary ethanol, or alcohol, is a supplemental source of calories for some primates. for example, slow lorises (nycticebus coucang) consume fermented nectars with a mean alcohol concentration of 0.6% (range: 0.0-3.8%). a similar behaviour is hypothesized for aye-ayes (daubentonia madagascariensis) based on a single point mutation (a294v) in the gene that encodes alcohol dehydrogenase class iv (adh4), the first enzyme to catabolize alcohol during digestion. the mutatio ...201627493777
why aye-ayes see blue.the capacity for cone-mediated color vision varies among nocturnal primates. some species are colorblind, having lost the functionality of their short-wavelength-sensitive-1 (sws1) opsin pigment gene. in other species, such as the aye-aye (daubentonia madagascariensis), the sws1 gene remains intact. recent studies focused on aye-ayes indicate that this gene has been maintained by natural selection and that the pigment has a peak sensitivity (lambda(max)) of 406 nm, which is -20 nm closer to the ...201224006536
pollination of ravenala madagascariensis and parkia madagascariensis by eulemur macaco in madagascar.primates are known to be important in dispersal of seeds of tropical rainforest trees, but their role in pollination is very poorly documented. although the 'traveller's palm' ravenala madagascariensis is widespread, only a single well-documented report exists for its pollination by malagasy prosimians. black lemurs, eulemur macaco, exploit nectaries of parkia as well as ravenala systematically at the massifs of ambato and lokobe, and almost certainly contribute substantially to their pollinatio ...19989751827
structural analysis of catalase from two musa accessions, fhia18 and williams, and from ravenala madagascariensis.nucleotide sequences of catalase were obtained following amplification using specific primers and were blasted against musa acuminata catalase 2 mrna from ncbi (157418810). clustering of the amino acid sequences from ncbi was done using clustal x. the latter revealed that fhia18 catalase is more related to ravenala madagascariensis (musa relative) catalase while the williams catalase is more related to a clade containing a musa acuminata (musa ancestor) catalase from ncbi. the tertiary structure ...200819374128
