FUNAMBULUS SPP., the STRIPED PALM SQUIRRELS 21.1 the Living Animal 21.1.1 Zoology the Striped Palm Squirrels Are Small Rodents W CHAPTER TWENTY-ONE FUNAMBULUS SPP., THE STRIPED PALM SQUIRRELS 21.1 The Living Animal 21.1.1 Zoology The striped palm squirrels are small rodents with a head and body length of about 13–15 cm, and a tail which is slightly longer than the body (Plate 29). The two common species of South Asia are the three-striped or southern Indian palm squirrel (Funambulus palmarum) with three white stripes running along its dark brown back, and the fi ve-striped or northern Indian palm squirrel (F. pennanti) with two additional white stripes running on the fl anks, parallel to the three dorsal stripes.1 The most important difference between the two spe- cies is that the fi ve-striped squirrel is essentially commensal with man. It has become almost as dependent on man for food and shelter as house rats and mice, and lives in crowded towns, cities and villages where it shelters in houses, gardens, groves, hedges and in roadside trees. The three-striped squirrel, on the contrary, is a forest animal. It has a particularly shrill bird-like call which it repeats again and again, accompanied by quick jerks of its tail. Both species inhabit the Indian peninsula from the base of the Himalayas southwards, but the fi ve-striped squirrel is more common in northern India, particularly in the drier and more arid portions and extends into the dry plains of the South. The three-striped squirrel predominates in the South, and in the moister parts of western and eastern India. Both species may, however, occur in the same area. 1 Two other Indian striped squirrels are the dusky-striped squirrel (Funambulus sub- lineatus) and the Himalayan striped squirrel (Callosciurus macclellandi). The fi rst squirrel has three pale stripes on a dark brown background, as if it is a bleached three-striped squirrel, and lives in the forests of south Indian hill ranges and Sri Lanka. The second squirrel has alternating black, brown, and buff stripes and lives in the hill forests of the Eastern Himalayas and Assam. These two squirrels keep to the densest cover, and are hardly ever seen. striped palm squirrels 271 21.1.2 Related Species There are non-striped squirrels on the subcontinent as well, but they all keep to dense cover, and are hardly seen. The Himalayan squirrels are the orange-bellied squirrel (Dremomys lokriah), and the hoary-bellied squirrel (Callosciurus pygerythrus), both restricted to the hills of Nepal, Sikkim, Bhutan and Assam. Three species of giant squirrels live on the subcontinent: the Indian or Malabar giant squirrel (Ratufa indica, fi g. 339) of peninsular India south of the Ganges, the grizzled giant squirrel (Ratufa macroura) of the hill ranges of South India and Sri Lanka, and the Malayan giant squirrel (Ratufa bicolor) of the hill ranges of Nepal, Sikkim, Bhutan and Assam. Giant squirrels are elegant and beautifully coloured animals, but are shy and live in the summits of the higher trees. Their large, globular nests in the branches are easier discovered than the animals themselves. The most amazing squirrels are without doubt the large fl ying squir- rels of the genera Eupetaurus, Petaurista, Petinomys, Hylopetes, and Belomys. They do not truly fl y, but merely glide or sail through the air with the help of a membrane which connects front and hind limbs (fi g. 340). They are nocturnal, in contrast to the other squirrels, and thus hardly ever seen. 21.1.3 Role of Squirrels in Society The fi ve-striped palm squirrel can be considered a commensal with humans. It lives in settlements and feeds on household waste and whatever suitable food it can fi nd. The fi ve-striped squirrel is easily tamed, but is not domesticated in the true sense, because its breeding is uncontrolled by humans. The three-striped squirrel lives in the forest and is not associated with humans. Squirrels seem to play no role in religion or traditional lore. Their only direct contribution is as small game animal for hill tribes, especially so the giant squirrels. 21.2 Squirrels in Stone One of the earliest and at the same time most appealing stone sculpture of the fi ve-striped palm squirrel decorates a railing pillar from Bharhut, Madhya Pradesh (c. 100 B.C.E.; fi g. 341).

    Hand-rearing and Rehabilitation of Orphaned Palm Squirrels, Funambulus sp. Devna Arora The Palm Squirrel A young 5-striped Indian palm squirrel Palm squirrels are palm-sized rodents with thick, bushy tails that belong to the genus Funambulus and the subfamily Calloscuirinae, a subfamily of squirrels found in Asia. The genus Funambulus comprises of 5 species of squirrels widely distributed in the Indian subcontinent with the subgenus of Prasadsciurus found right up to Iran. For ease of classification and understanding of behaviour, I prefer to group these squirrels based on their proximity to human settlements. The two species of palm squirrels commonly found in urban, suburban and rural landscapes are: • Indian 3-Striped Palm Squirrel (Funambulus palmarum) which has a more southern distribution and is commonly found in peninsular India and Sri Lanka. Rehabber’s Den © 2013 1 Hand-rearing and rehabilitation of orphaned palm squirrels, Funambulus sp. • Indian 5-Striped Palm Squirrel (Funambulus pennantii) which has a more northern distribution in India and in commonly found in central and northern India as well as Nepal, Pakistan and Iran. The two species can easily be distinguished by counting the number of paler coloured stripes on the squirrel’s back. The squirrels range from 22.5 cm to 40 cm in length, which includes a tail of 11–12 cm long, and weigh between 100–200 gm. Data suggests that palm squirrels live on average for 5-6 years in captivity although individuals have been known to live longer. They may only breed seasonally in the northern distribution of their ranges but breed all-year round otherwise.

Graham Clark The contribution of Blastocystis from non-human hosts to zoonotic transmission is only partly known. The objective of this study was to determine the distribution of Blastocystis genetic subtypes in dif- ferent animal species in United Arab Emirates. A total of 114 stool samples were tested using PCR of the small subunit (SSU) rRNA gene and sequence analysis. Twenty-three Blastocystis-positive sam- ples were identified. The following detection rates were observed: cattle, 22.7%; sheep, 63.6%; rabbits, 33.3%; rodents, 37.5%; reptiles, 21.2%. Four subtypes were identified in this study; ST4, ST10, ST14, and ST17; ST10 was isolated from sheep and cattle, corroborating previous data indicating that these are natural hosts for this subtype.

  • Phylogenies of Flying Squirrels (Pteromyinae)
    Journal of Mammalian Evolution, Vol. 9, No. 1/2, June 2002 (© 2002) Phylogenies of Flying Squirrels (Pteromyinae) Richard W. Thorington, Jr.,'''* Diane Pitassy,^ and Sharon A. Jansa^ The phylogeny of flying squirrels was assessed, based on analyses of 80 morphological characters. Three published hypotheses were tested with constraint trees and compared with trees based on heuristic searches, all using PAUP*. Analyses were conducted on unordered data, on ordered data (Wagner), and on ordered data using Dollo parsimony. Compared with trees based on heuristic searches, the McKenna (1962) constraint trees were consistently the longsst, requiring 8-11 more steps. The Mein (1970) constraint trees were shorter, requiring five to seven steps more than the unconstrained trees, and the Thorington and Darrow (20(X)) constraint trees were shorter yet, zero to one step longer than the corresponding unconstrained tree. In each of the constraint trees, some of the constrained nodes had poor character support. The heuristic trees provided best character support for three groups, but they did not resolve the basal trichotomy between a Glaucomys group of six genera, a Petaurista group of four genera, and a Trogopterus group of four genera. The inclusion of the small northern Eurasian flying squirrel, Pteminys, in the Peiaiiiisia group of giant South Asian flying squirrels is an unexpected hypothesis. Another novel hypothesis is the inclusion of the genus Aemmys, large animals from the Sunda Shelf, with the Trogopterus group of smaller "complex-toothed flying squirrels" from mainland Malaysia and southeast Asia. We explore the implications of this study for future analysis of molecular data and for past and future interpretations of the fossil record.

Hoffmannb a Department of Biological Science, Florida State University, Tallahassee, FL 32306-1100, USA b Department of Vertebrate Zoology, National Museum of Natural History, Smithsonian Institution, MRC-108, Washington, DC 20560, USA Received 24 February 2003; revised 15 May 2003 Abstract Although the family Sciuridae is large and well known, phylogenetic analyses are scarce. We report on a comprehensive mo- lecular phylogeny for the family. Two nuclear genes (c-myc and RAG1) comprising approximately 4500 bp of data (most in exons) are applied for the first time to rodent phylogenetics. Parsimony, likelihood, and Bayesian analyses of the separate gene regions and combined data reveal five major lineages and refute the conventional elevation of the flying squirrels (Pteromyinae) to subfamily status. Instead, flying squirrels are derived from one of the tree squirrel lineages. C-myc indels corroborate the sequence-based topologies. The common ancestor of extant squirrels appears to have been arboreal, confirming the fossil evidence. The results also reveal an unexpected clade of mostly terrestrial squirrels with African and Holarctic centers of diversity. We present a revised classification of squirrels. Our results demonstrate the phylogenetic utility of relatively slowly evolving nuclear exonic data even for relatively recent clades. Ó 2003 Elsevier Science (USA). All rights reserved. 1.
