| praomys tullbergi (muridae, rodentia) genome architecture decoded by comparative chromosome painting with mus and rattus. | the order rodentia and in particular the muridae are characterised by extremely high rates of chromosome evolution and remarkable chromosome diversity. the praomys group (murinae, muridae and rodentia) constitutes a diverse and abundant group divided into two complexes, the jacksoni complex and the tullbergi complex which includes the species praomys tullbergi. comparative chromosome painting using the two index genomes, mus musculus and rattus norvegicus, was performed resulting in a high resol ... | 2012 | 22847644 |
| the karyotype and sex chromosomes of praomys tullbergi (muridae, rodentia): a detailed characterization. | here we present the first detailed characterization of praomys tullbergi karyotype, enlightening several chromosome features such as constitutive heterochromatin, telomeric and line-1 sequences. the combination of these approaches provided some interesting insights about the genome organization of this african species, which is one of the tullbergi complex elements, a group of species belonging to murinae (rodentia, muridae). evolutionary considerations on praomys chromosomes were also achieved, ... | 2008 | 17714950 |
| spatio-temporal variation in small mammal species richness, relative abundance and body mass reveal changes in a coastal wetland ecosystem in ghana. | coastal wetlands in ghana are under severe threat of anthropogenic drivers of habitat degradation and climate change, thereby increasing the need for assessment and monitoring to inform targeted and effective conservation of these ecosystems. here, we assess small mammal species richness, relative abundance and body mass in three habitats at the muni-pomadze ramsar site of ghana, and compare these to baseline data gathered in 1997 to evaluate changes in the wetland ecosystem. small mammals were ... | 2016 | 27154051 |
| impact of mining and forest regeneration on small mammal biodiversity in the western region of ghana. | much of the terrestrial biodiversity in sub-saharan africa is supported by tropical rainforest. natural resource development, particularly surface mining in the rainforest, poses great risks to the region's rich and endemic biodiversity. here, we assessed the impact of surface mining and the success of forest rehabilitation on small mammal diversity in the western region of ghana. we surveyed small mammals in the project area and two adjoining forest reserves (control sites) before the mining op ... | 2017 | 28451959 |
| line-1 retrotransposons: from 'parasite' sequences to functional elements. | long interspersed nuclear elements-1 (line-1) are the most abundant and active retrotransposons in the mammalian genomes. traditionally, the occurrence of line-1 sequences in the genome of mammals has been explained by the selfish dna hypothesis. nevertheless, recently, it has also been argued that these sequences could play important roles in these genomes, as in the regulation of gene expression, genome modelling and x-chromosome inactivation. the non-random chromosomal distribution is a strik ... | 2015 | 25106509 |
| hidden heterochromatin: characterization in the rodentia species cricetus cricetus, peromyscus eremicus (cricetidae) and praomys tullbergi (muridae). | the use of in situ restriction endonuclease (re) (which cleaves dna at specific sequences) digestion has proven to be a useful technique in improving the dissection of constitutive heterochromatin (ch), and in the understanding of the ch evolution in different genomes. in the present work we describe in detail the ch of the three rodentia species, cricetus cricetus, peromyscus eremicus (family cricetidae) and praomys tullbergi (family muridae) using a panel of seven res followed by c-banding. co ... | 2009 | 21637647 |
