Activity Patterns in the Mole-Rats Tachyoryctes Splendens and Heliophobius Argenteocinereus
ACTIVITY PATTERNS IN THE MOLE-RATS TACHYORYCTES SPLENDENS AND HELIOPHOBIUS ARGENTEOCINEREUS JENNIFER u. M. JAR VIS *Zoology Department, University of Nairobi, Kenya ABSTRACT Activity in two unrelated genera of mol~rats, Tachyoryctes and Heiiophobius, was studied in the field by recording the movements of animals tagged with radioactive wire. Tachyoryctes shows a single marked activity peak and only leaves its nest between 10.00 and 19.00 hour. Heiiophobills shows a more dispersed and prolonged activity pattern although peak activity occurs over approximately the same period as in Tachyoryctes. Heilophoblus spends over 50 % of the day out of its nest, Tachyoryctes, under 25%. These differences can be attributed to a different function of the nest in the two genera (Tachy oryctes has a multipurpose nest; Heiiophoblus uses its nest solely for rest), and also to the fact that Tachyoryctes has light-sensitive eyes whereas Heiiophoblus appears unable to appreciate light; Tachyoryctes periodically comes to the surface to forage and this exposure to light may trigger the 24-hour activity cycle. INTRODUCTION The mole-rats Tachyoryctes splendens (Ruppell) and Heliophobius argenteocinereus (Peters) are strictly fossorial rodents, they live in burrow systems of their own making and rarely come above ground. Field observations of their activity are severely hampered by their fossorial existence. This indeed has, until recently, been a limiting factor in studies on activity in many fossorial . mammals. ) 0 1 The development of radioactive tagging techniques has made it possible to study the activity 0 2 of fossorial mammals in their burrows and under natural conditions.

The phylogenetic tree indicated a valid status for the genera Eospalax and Myospalax, and an independent species status for E. baileyi and E. cansus. The demographical population history of E. baileyi showed that the effective population size remained stable between 1.00 and 0.50 million years ago (Mya), increased quickly to a peak and fluctuated dramatically between 0.50 and 0.20 Mya, after which a stable level was maintained from 0.20 Mya to the present. -

BMC Genomics 2014, 15:32 http://www.biomedcentral.com/1471-2164/15/32 RESEARCH ARTICLE Open Access Transcriptome sequencing and phylogenomic resolution within Spalacidae (Rodentia) Gong-Hua Lin1, Kun Wang2, Xiao-Gong Deng1,3, Eviatar Nevo4, Fang Zhao1, Jian-Ping Su1, Song-Chang Guo1, Tong-Zuo Zhang1* and Huabin Zhao5* Abstract Background: Subterranean mammals have been of great interest for evolutionary biologists because of their highly specialized traits for the life underground. Owing to the convergence of morphological traits and the incongruence of molecular evidence, the phylogenetic relationships among three subfamilies Myospalacinae (zokors), Spalacinae (blind mole rats) and Rhizomyinae (bamboo rats) within the family Spalacidae remain unresolved. Here, we performed de novo transcriptome sequencing of four RNA-seq libraries prepared from brain and liver tissues of a plateau zokor (Eospalax baileyi) and a hoary bamboo rat (Rhizomys pruinosus), and analyzed the transcriptome sequences alongside a published transcriptome of the Middle East blind mole rat (Spalax galili). We characterize the transcriptome assemblies of the two spalacids, and recover the phylogeny of the three subfamilies using a phylogenomic approach. Results: Approximately 50.3 million clean reads from the zokor and 140.8 million clean reads from the bamboo ratwere generated by Illumina paired-end RNA-seq technology. All clean reads were assembled into 138,872 (the zokor) and 157,167 (the bamboo rat) unigenes, which were annotated by the public databases: the Swiss-prot, Trembl, NCBI non-redundant protein (NR), NCBI nucleotide sequence (NT), Gene Ontology (GO), Cluster of Orthologous Groups (COG), and Kyoto Encyclopedia of Genes and Genomes (KEGG). -

E-mail: Chongxuan Han, [email protected]; Xiaoning Nan, [email protected]. Received 24 October 2019; revised 19 February 2020; accepted 2 March 2020 Abstract. Zokor (Myospalacinae) is one of the subterranean rodents, endemic to east Asia. Due to the convergent and parallel evolution induced by its special lifestyles, the controversies in morphological classification of zokor appeared at the level of family and genus. To resolve these controversies about taxonomy and phylogeny, the phylogenetic relationships of 20 species of Muroidea and six species of zokors were studied based on complete mitochondrial genome and mitochondrial Cytb gene, respectively. Phylogeny analysis of 20 species of Muroidea indicated that the zokor belonged to the family Spalacidae, and it was closer to mole rat rather than bamboo rat. Besides, by investigating the phylogenetic relationships of six species of zokors, the status of two genera of Eospalax and Myospalax was affirmed because the two clades differentiated in phylogenetic tree represented two types of zokors, convex occiput type and flat occiput type, respectively. -
Chapter 4 the Antiquity of Rhizomys and Independent Acquisition of Fossorial Traits in Subterranean Muroids
Chapter 4 The Antiquity of Rhizomys and Independent Acquisition of Fossorial Traits in Subterranean Muroids LAWRENCE J. FLYNN1 ABSTRACT In parallel with the growing body of molecular data bearing on the relationships of muroids, particularly subterranean lineages, the relevant fossil record has improved to the point that its data constrain scenarios of evolution about both the timing and mode of evolution of burrowing muroids, especially bamboo rats, blind mole rats, and zokors. Morphologists have considered these groups phylogenetically distinct from each other, but the three lineages appear to be related as a monophyletic Family Spalacidae, sister taxon to all other living muroids, based on both nuclear and mitochondrial genes. Although living genera are fully subterranean, the fossil record shows that the three groups evolved burrowing characteristics independently. Bamboo rats (Rhizomyinae) have the longest fossil record, extending into the Late Oligocene, but do not show fossorial traits until the Late Miocene. Blind mole rats (Spalacinae) have a fossil record nearly that long, and its early members also lack burrowing traits. Zokors (Myospalacinae) show characteristics considered derived relative to other groups, and have a shorter fossil record. The fossil record of the Tribe Rhizomyini, living Asian bamboo rats, extends to about 10 million years ago, with early species distinct at the generic level from living Rhizomys. The oldest well- known species assignable to an extant genus is Rhizomys (Brachyrhizomys) shansius from the early Pliocene of Yushe Basin, China, north of the geographic range of modern Rhizomys.A hypothesis of close relationship of bamboo rats, blind mole rats, and zokors leads to a reevaluation of affinities of certain Asian fossil taxa and reevaluation of polarity of some features, but molecular data are not yet robust enough to clarify interrelationships of the groups. -

IRBP) in Ground Squirrels and Blind Mole Rats
Molecular Evolution of the Interphotoreceptor Retinoid Binding Protein (IRBP) in Ground Squirrels and Blind Mole Rats Research Thesis Presented in partial fulfillment of the requirements for graduation with Research Distinction in Biology in the Undergraduate Colleges of The Ohio State University by Bethany N. Army The Ohio State University December 2015 Project Advisor: Dr. Ryan W. Norris, Department of Evolution, Ecology and Organismal Biology Abstract Blind mole rats are subterranean rodents and spend most of their lifetime underground. Because these mammals live in a dark environment, their eyes have physically changed and even the role played by their eyes has changed. The processing of visual information begins in the retina, with the detection of light by photoreceptor cells. Interphotoreceptor retinoid binding protein (IRBP) is a transport protein, which facilitates exchange between photoreceptors and retinal-pigmented epithelium. The IRBP gene has been commonly used in rodent phylogenetic analyses, so I analyzed IRBP in blind mole rats to interpret its evolution and to see if there were any changes among the amino acids in the protein. To do this I used molecular data (cytochrome b and IRBP) from two groups of rodents, the muroids and the marmotines. I constructed phylogenetic trees and interpreted the amino acid sequence of IRBP. Blind mole rats had a slower rate of evolution than expected, but there were changes along the amino acid sequence of IRBP, which may indicate that the IRBP gene is functioning in a specialized way to meet the needs of the particular lifestyle of this mammal. Introduction: Blind mole rats, subfamily Spalacinae, are burrowing mammals that spend most of their life underground. -

The current study investigated the breeding patterns of a wild- caught population from Tanzania where the putative species H. emini (Noack 1894) resides. Individuals were collected on a monthly basis for an entire calendar year. Assessment of foetus presence, gonadal histology, reproductive tract morphometrics in combination with gonadal steroid (plasma progesterone and oestradiol-17β in females and testosterone in males) measurements and field observations revealed that rainfall is important for the onset of breeding. -

Schlitter, Ph.D. Chairperson Vice President for Research and Dean of Graduate Studies Date: October 24, 2008 Abstract Molecular and paleontological approaches have produced extremely different estimates for divergence times among orders of placental mammals and within rodents with molecular studies suggesting a much older date than fossils. We evaluated the conflict between the fossil record and molecular data and find a significant correlation between dates estimated by fossils and relative branch lengths, suggesting that molecular data agree with the fossil record regarding divergence times in rodents.
