| confirmation of pleisiomorphic daily torpor in mammals: the round-eared elephant shrew macroscelides proboscideus (macroscelidea). | the characteristics of daily torpor were measured in the round-eared elephant shrew macroscelides proboscideus (macroscelidea) in response to ambient temperature and food deprivation. elephant shrews are an ancient mammal order within a superordinal african clade including hyraxes, elephants, dugongs and the aardvark. m. proboscideus only employed torpor when deprived of food; torpor did not occur under an ad libitum diet at ambient temperatures of 10, 15 and 25 degrees c. torpor bout duration r ... | 1999 | 10595314 |
| a chromosome painting test of the basal eutherian karyotype. | we studied the chromosomes of an afrotherian species, the short-eared elephant shrew macroscelides proboscideus with traditional banding techniques and mapped the homology to human chromosomes by in-situ hybridization of human chromosome paints. here we present for the first time the karyotype of this species, including banding patterns. the chromosome painting allowed us to test various hypotheses of the ancestral eutherian karyotype, the validity of the radical taxonomic assemblage known as af ... | 2004 | 14984101 |
| small mammal seed consumption in the karoo, south africa: further evidence for divergence in desert biotic processes. | annual seed consumption by a small mammal community in the semi-arid karoo, south africa, was calculated using population, biomass and dietary estimates and published estimates of field metabolic rate. the community comprised a macroscelid elephant shrew macroscelides proboscideus, and two rodents gerbillurus paeba and desmodillus auricularis. only g. paeba consumed seed during the study, and then in low amounts (annual mean = 0.4% of diet, insects = 53%, herbage = 47%), with m. proboscideus and ... | 1992 | 28311875 |
| comparative anatomy of neonates of the three major mammalian groups (monotremes, marsupials, placentals) and implications for the ancestral mammalian neonate morphotype. | the existing different modes of reproduction in monotremes, marsupials and placentals are the main source for our current understanding of the origin and evolution of the mammalian reproduction. the reproductive strategies and, in particular, the maturity states of the neonates differ remarkably between the three groups. monotremes, for example, are the only extant mammals that lay eggs and incubate them for the last third of their embryonic development. in contrast, marsupials and placentals ar ... | 2017 | 28960296 |
| redescription of maupasina weissi (seurat, 1913) (nematoda: ascaridida) from sengis, elephantulus spp. and macroscelides proboscideus (shaw) (macroscelidea), in africa. | maupasina weissi (seurat, 1913), is redescribed from the eastern rock sengi, elephantulus myurus thomas & schwann, from limpopo province and compared with material collected from free state and north west provinces, south africa, as well as the description of the type-material from south tunisia. distinguishing features of the species include a corona radiata of 12 pointed leaflike elements, a complex bipartite buccal capsule with 3 large bicuspid denticular lobes and 4 smaller club-shaped lobes ... | 2018 | 30341721 |
