“…The mean serum ALT and ALP values were lower, while the mean serum AST and total bilirubin values were slightly higher than that reported by Onwuka et al (2003) for juvenile African giant rat. In this study, serum ALT activity was higher in females than in males, and this was in agreement with that reported by Onwuka et al (2003). Serum total protein level was lower in the studied rat than that reported for juvenile laboratory rat, and may be attributed to diet; as laboratory rat are fed standard diet in the experimental animal house, while the wild rat has difficulty in accessing food (protein) (Madjdzadeh et al 2011).…”

“…In available literature, there are reasonable amount of haematological and serum biochemistry values of rodents such as the birch mouse (Wolk 1985), juvenile laboratory rat (Ihedioha et al 2004), African soft-furred rat (Kagira et al 2005), wild grasscutter (Opara et al 2006) and adult wild African giant rat (C. gambianus) (Oyewale et al 1998a(Oyewale et al , 1998bOlayemi & Adeshina 2002;Cooper & Erlwanger 2007), but only little information is available on the haematology and serum biochemistry values of the juvenile wild African giant rat (Nssien et al 2002;Onwuka et al 2003). Due to the variations in the haematological and serum biochemistry values, there is need for each clinic to establish its own reference range of values for relevant animal population.…”

“…Several publications, employing alternative techniques such as karyotyping (Granjon et al ., 1992; Codjia et al ., 1994; Dobigny, Nomao & Gautun, 2002; Corti et al ., 2005), plasma biochemical properties (Nssien et al ., 2002; Onwuka et al ., 2003), multivariate craniometry (Bellier, 1973), and the anatomy of the gastrointestinal tract (Ali et al ., 2008), have attempted to provide additional information useful for characterization of the various giant pouched rat species. However, the taxonomic impact of these studies has been of restricted importance because they were conducted on limited specimen collections, underscoring the need for more investigations covering the entire range of these rodents.…”

Our study combined a mitochondrial cytochrome b phylogeny with cranial measurements from giant pouched rats collected across sub‐Saharan Africa. The mitochondrial phylogeny resolves two West African clades and a clade with east and central Africa representatives. This last clade can be further divided into four subclades. Altogether they represent six species (Cricetomys gambianus, Cricetomys ansorgei, Cricetomys emini, and three undescribed taxa) that can be distinguished on the basis of their mitochondrial DNA sequences and craniometry. In the absence of adequate craniometric data the existence of Cricetomys kivuensis cannot be confirmed by our data. Our combined molecular and craniometric data allowed us to broadly delineate the distribution ranges of the detected species. Cricetomys gambianus occurs in the savannah and forest clearings of West Africa. Cricetomys ansorgei is distributed in the savannah of East and southern Africa. Cricetomys emini, as currently recognized across the Guineo‐Congolian forest of Africa, is shown to be diphyletic. Cricetomys sp. 1, a separate operational taxonomic unit closely resembling C. emini, occurs in the forest zone of West Africa. An undescribed sister‐species of C. ansorgei, Cricetomys sp. 2, occurs in the forest of Central Africa along the left bank of the Congo River. Cricetomys sp. 3 occurs on the right bank of the Congo River from Cameroon to the Republic of Congo, whereas the true C. emini also occurs on the right bank of the Congo River but appears to be restricted to the Democratic Republic of Congo. Cranial phenotype within the genus tends to conform to ecological zonation (either forest or savannah) rather than to phylogenetic affiliation of the species concerned, suggesting that diversifying selection across environmental gradients could be responsible for biological diversification within the genus.

“…Although we did not distinguish between the isoforms in this study, likely sources of increased ALP activity include the bone and corticosteroid-induced forms (Stockham and Scott, 2002). Increased ALP activity in juvenile animals has been noted in previous studies of freeranging animals, including island foxes (Borjesson et al, 2000;Crooks et al, 2000;Stockham and Scott, 2002;Onwuka et al, 2003). The concurrent increase in ALT activity in juvenile foxes may suggest steroid stress, although leukogram changes supportive of this diagnosis were not present.…”

ABSTRACT:Hematologic and serum biochemical data collected must be interpreted by comparison with normal reference intervals generated from healthy animals, within a similar population, because many blood parameters are influenced by diet, environment, and stress. Species-specific reference intervals for the endangered island fox (Urocyon littoralis) are not available. We reviewed hematology and serum biochemistry panels from 280 island foxes sampled from 1999-2008 and established normal reference intervals from clinically healthy foxes using a nonparametric approach. Blood parameters were analyzed for differences in age, sex, island of origin, and captivity status. Alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, and creatine kinase activities, as well as calcium and phosphorus concentrations, were significantly higher in juveniles than in adults, but total protein and globulin concentration was lower for juveniles than for adults. Lymphocyte and eosinophil counts, and blood urea nitrogen (BUN) concentration, in foxes from the northern Channel islands of California, USA (Santa Cruz, Santa Rosa, and San Miguel) were higher when compared with foxes from Santa Catalina Island to the south. Higher lymphocyte and eosinophil numbers in the northern island foxes may be associated with increased levels of parasitism on the northern islands. Differences in BUN concentration in both free-ranging and captive foxes may reflect dietary differences among islands. Although aggressive conservation programs have been enacted, island foxes are still susceptible to infectious and neoplastic diseases and, potentially, to toxins. Island fox species-specific reference intervals will enable managers and veterinarians to better care for sick and injured foxes and will contribute to future population health monitoring.
