| [comparative anatomical studies of the vomeronasal complex and the rostral palate of various mammals. i]. | the anatomy of the vomeronasal complex and, in connection with this, the structures of the rostral palate were studied in different species of mammals, namely members of the order marsupialia, scandentia, insectivora, primates, rodentia, and lagomorpha. the following results were obtained: the organs of jacobson of all forms studied are well-developed. the organ of jacobson is situated at the base of the nasal septum and opens rostrally, always closely connected to the nasopalatine duct. even in ... | 1984 | 6489726 |

| retroviral envelope syncytin capture in an ancestrally diverged mammalian clade for placentation in the primitive afrotherian tenrecs. | syncytins are fusogenic envelope (env) genes of retroviral origin that have been captured for a function in placentation. syncytins have been identified in euarchontoglires (primates, rodents, leporidae) and laurasiatheria (carnivora, ruminants) placental mammals. here, we searched for similar genes in species that retained characteristic features of primitive mammals, namely the malagasy and mainland african tenrecidae. they belong to the superorder afrotheria, an early lineage that diverged fr ... | 2014 | 25267646 |
| two new eimerians (apicomplexa) from insectivorous mammals in madagascar. | fecal samples from 126 insectivorous mammals in madagascar were collected between spring 1999 and fall 2001. in the afrosoricida, 21 species in 5 genera were sampled, including 17 species of microgale (31/96, 32% infected), hemicentetes semispinosus (1/2, 50%), oryzorictes hova (1/5, 20%), setifer setosus (8/13, 61.5%), and tenrec ecaudatus (5/8, 62.5%); in the soricomorpha, only suncus murinus was examined and 1/2 (50%) were infected. two morphotypes of eimeriid oocysts, representing 2 presumpt ... | 2011 | 21506791 |
| are tropical small mammals physiologically vulnerable to arrhenius effects and climate change? | there is some urgency in the necessity to incorporate physiological data into mechanistic, trait-based, demographic climate change models. physiological responses at the individual level provide the mechanistic link between environmental changes and individual performances and hence population dynamics. here we consider the causal relationship between ambient temperature (ta) and metabolic rate (mr), namely, the arrhenius effect, which is directly affected by global warming through increases in ... | 2014 | 24457919 |
| somatovisceral projections from spinal cord and dorsal column nuclei to the thalamus in hedgehog tenrecs. | in order first to overcome the difficulties in understanding the increasing amount of information available regarding the mammalian somatosensory thalamus, and then to correlate the findings among different species and integrate them into a general concept of thalamic organization, the present study investigated the spinothalamic and medial lemniscal projections in madagascan hedgehog tenrecs (echinops telfairi and setifer setosus). tracer substances were injected into the dorsal column nuclei a ... | 1994 | 7976007 |
| tectal and related target areas of spinal and dorsal column nuclear projections in hedgehog tenrecs. | the terminal distributions of spinal and dorsal column nuclear projections to tectum, pretectum, and central gray of hedgehog tenrecs (echinops telfairi and setifer setosus) were investigated using anterograde axonal flow and various tracer substances. in the inferior colliculus, the densest and most extensive mesencephalic projections were found within the pericentral regions. one target area, referred to as the external portion of the inferior colliculus, was represented as a semicircle of gra ... | 1993 | 8237220 |
| retinofugal projections in hedgehog-tenrecs (echinops telfairi and setifer setosus). | using the autoradiographic tracing technique the retinal projections were studied in the tenrecs, echinops telfairi and setifer setosus (insectivora, tenrecidae). bilateral projections were found to the n. suprachiasmaticus, the anterior hypothalamic area, the dorsal and ventral lateral geniculate bodies, the pretectal olivary nucleus and the superior colliculus. the contralateral projections were usually more intense than the ipsilateral ones except the retinohypothalamic connections. a partial ... | 1988 | 3377203 |
| increased homeothermy during reproduction in a basal placental mammal. | homeothermic endothermy, the maintenance of a high and stable body temperature (tb) using heat produced by elevated metabolism, is energetically expensive. there is increasing evidence that the earliest endotherms were heterotherms that, rather than maintaining strict homeothermy, allowed tb to fluctuate with large variations between active and rest-phase tb. the high level of homeothermy observed in modern mammals is therefore likely to have evolved from an ancestral heterothermic state. one of ... | 2014 | 24501138 |
| spontaneous neoplasia in four captive greater hedgehog tenrecs (setifer setosus). | little information is available about diseases and pathology of species within the family tenrecidae, including the greater hedgehog tenrec (setifer setosus), a madagascan insectivore. this report summarizes necropsy and histopathologic findings of neoplasia in four captive greater hedgehog tenrecs. although only four animals are included in this report, neoplasia seems to be a common and significant source of morbidity and mortality in greater hedgehog tenrecs. types of neoplasia identified inc ... | 2008 | 18817002 |

| molecular detection of rickettsia spp., borrelia spp., bartonella spp. and yersinia pestis in ectoparasites of endemic and domestic animals in southwest madagascar. | little is known about the presence of vector-borne bacteria in southwest madagascar. anthropogenic alteration of natural habitats represents an important driver for the emergence of new diseases. especially the involvement of livestock and the involuntary maintaining of invasive synanthropic animals (particularly rats) facilitate disease transmission from wildlife to humans and associated animals and vice versa. the dissemination or acquisition of ectoparasites is most likely in regions where hu ... | 2020 | 31935354 |
| geographical distribution and relative risk of anjozorobe virus (thailand orthohantavirus) infection in black rats (rattus rattus) in madagascar. | hantavirus infection is a zoonotic disease that is associated with hemorrhagic fever with renal syndrome and cardiopulmonary syndrome in human. anjozorobe virus, a representative virus of thailand orthohantavirus (thaiv), was recently discovered from rodents in anjozorobe-angavo forest in madagascar. to assess the circulation of hantavirus at the national level, we carried out a survey of small terrestrial mammals from representative regions of the island and identified environmental factors ass ... | 2018 | 29743115 |
| presence of the oriental rat flea (siphonaptera: pulicidae) infesting an endemic mammal and confirmed plague circulation in a forest area of madagascar. | the oriental rat flea, xenopsylla cheopis (rothschild 1903), is a cosmopolitan flea usually found infesting domestic rats. this flea is a well-known major human plague vector in madagascar. as part of field sampling, fleas and small mammals were collected in the village of south andranofeno and the natural reserve of sohisika, two sites of the district of ankazobe, located in the central highlands of madagascar. rats inside houses and forest small mammals were trapped using besancon technical se ... | 2020 | 32101616 |
