body shape and life style of the extinct balearic dormouse hypnomys (rodentia, gliridae): new evidence from the study of associated skeletons.hypnomys is a genus of gliridae (rodentia) that occurred in the balearic islands until late holocene. recent finding of a complete skeleton of the chronospecies h. morpheus (late pleistocene-early holocene) and two articulated skeletons of h. cf. onicensis (late pliocene) allowed the inference of body size and the calculation of several postcranial indexes. we also performed a factorial discriminant analysis (fda) in order to evaluate locomotory behaviour and body shape of the taxa. using allome ...201021209820
third lineage of rodent eimerians: morphology, phylogeny and re-description of eimeria myoxi (apicomplexa: eimeriidae) from eliomys quercinus (rodentia: gliridae).coccidian oocysts from feces of 46 individuals of the garden dormouse, eliomys quercinus (rodentia: gliridae), were morphologically and molecularly characterized. both morphological and sequence data (18s rdna and orf 470) showed low variability, indicating that all samples represent a single species. by comparison with published morphological descriptions of coccidia from glirid rodents, we determined that the samples represent eimeria myoxi. molecular data suggest that this species does not fa ...201121810299
behavioural development of the gardendormouse, eliomys quercinus l. : ii) an open-field study.in order to study the behavioural development of the gardendormouse the open-field method was used. each young dormouse was tested for 3 minutes every day. locomotion, urination, defecation and vocalizations were recorded and quantified. the tests were made from birth to the 30 th day of life. the locomotory activity increased progressively and reached a maximum on the 28th day. from birth to the 18th day of life the number of whistles emitted by the young dormice increased as the locomotory act ...198424896523
late-born intermittently fasted juvenile garden dormice use torpor to grow and fatten prior to hibernation: consequences for ageing processes.torpor is thought to slow age-related processes and to sustain growth and fattening of young individuals. energy allocation into these processes represents a challenge for juveniles, especially for those born late in the season. we tested the hypothesis that late-born juvenile garden dormice (eliomys quercinus) fed ad libitum ('al', n = 9) or intermittently fasted ('if', n = 9) use short torpor bouts to enhance growth and fat accumulation to survive winter. if juveniles displayed more frequent a ...201425377448
differences in growth rates and pre-hibernation body mass gain between early and late-born juvenile garden dormice.juvenile hibernators have to allocate energy to both growth and fattening, to survive winter, and to avoid possible disadvantages during their first reproductive season. being born late in the active season may have important effects on growth and fattening. this study aimed at determining potential differences in rates and maximal level of growth, and in pre-hibernation body fat mass between early and late-born juvenile garden dormice (eliomys quercinus), and kept in outdoor enclosures with ad ...201727480769
communal nesting in the garden dormouse (eliomys quercinus).communal nesting has been described in many rodents including some dormouse species. in this study, we report the existence of this reproductive strategy in the garden dormouse eliomys quercinus. data was recorded by checking natural nests and nest-boxes from 2003 to 2013 in se spain. pups and adults dormice found in nests were captured and marked. overall, 198 nests were found: 161 (81.31%) were singular nests and 37 (18.69%) were communal nests. communal nests were composed by different combin ...201727908663
a taxonomic review of hymenolepidids (eucestoda, hymenolepididae) from dormice (rodentia, gliridae), with descriptions of two new species.in present study the systematic and taxonomic position of hymenolepidids parasitizing rodents of the family gliridae from europe and central asia is discussed. hymenolepis myoxi is redescribed on the basis of the type material from the fat dormouse glis glis deposited in the collection of the museum für naturkunde, berlin, germany. significant corrections of morphologically distinctive characters attributable to h. myoxi include: (1) recognition of a rudimentary rostellar apparatus; (2) absence ...201728030358
potential of pest regulation by insectivorous birds in mediterranean woody crops.regulation of agricultural pests managing their natural enemies represents an alternative to chemical pesticides. we assessed the potential of insectivorous birds as pest regulators in woody crops located in central spain. a total of 417 nest boxes installed in five field study sites (one vineyard, two fruit orchards, and two olive groves) were monitored for use and breeding of insectivorous birds and other species for four consecutive years (2013-2016). at all field sites except the two olive g ...201728877166
implications of being born late in the active season for growth, fattening, torpor use, winter survival and fecundity.for hibernators, being born late in the active season may have important effects on growth and fattening, hence on winter survival and reproduction. this study investigated differences in growth, fattening, energetic responses, winter survival and fecundity between early-born ('eb') and late-born ('lb') juvenile garden dormice (eliomys quercinus). lb juveniles grew and gained mass twice as fast as eb individuals. torpor use was low during intensive growth, that are, first weeks of body mass gain ...201829458712
long-term data from a small mammal community reveal loss of diversity and potential effects of local climate change.climate change affects distribution and persistence of species. however, forecasting species' responses to these changes requires long-term data series that are often lacking in ecological studies. we used 15 years of small mammal trapping data collected between 1978 and 2015 in 3 areas at doñana national park (southwest spain) to (i) describe changes in species composition and (ii) test the association between local climate conditions and size of small mammal populations. overall, 5 species wer ...201729492011
dietary lipids affect the onset of hibernation in the garden dormouse (eliomys quercinus): implications for cardiac function.dietary lipids strongly influence patterns of hibernation in heterotherms. increased dietary uptake of n-6 polyunsaturated fatty acids (pufas), particularly of linoleic acid (la, c18:2 n-6), enables animals to reach lower body temperatures (tb), lengthens torpor bout duration, and results in lower energy expenditure during hibernation. conversely, dietary n-3 pufa impacts negatively on hibernation performance. pufa in surrounding phospholipids (pls) presumably modulate the temperature-dependent ...201830279661
gimme shelter: the effect of rocks and moonlight on occupancy and activity pattern of an endangered rodent, the garden dormouse eliomys quercinus.information on spatial behaviour and temporal activity patterns is paramount for the conservation of animal species. this is particularly true for endangered taxa that are threatened by ongoing climatic and environmental changes. the garden dormouse eliomys quercinus is a native european rodent (family gliridae), whose populations are declining throughout the continent. notwithstanding this, neither international nor national laws explicitly require mandatory monitoring of populations. as a resu ...202031730883
review of records of hymenolepidids (eucestoda: hymenolepididae) from dormice (rodentia: gliridae) in europe, with a redescription of armadolepis spasskyi tenora & baruš, 1958 and the description of a. genovi n. sp.armadolepis (armadolepis) spasskyi tenora & baruš, 1958 is redescribed on the basis of the type-series consisting of the holotype from the garden dormouse eliomys quercinus (linnaeus) (type-host) and a paratype from the forest dormouse dryomys nitedula (pallas); the occurrence of this species in the fat dormouse glis glis (linnaeus) cannot be confirmed due to the lack of specimens from this host species both in the type-series and other studied samples. the main corrections in the diagnostic cha ...202031933036
the ratio of linoleic and linolenic acid in the pre-hibernation diet influences nfκb signaling in garden dormice during torpor.the fatty acid composition of a pre-hibernation diet can influence the depth and duration of metabolic suppression achieved by hibernators. more specifically, a diet high in n-6 polyunsaturated fatty acids (pufas) relative to n-3 pufas is essential to maximize torpor expression. however, few studies have investigated how diets with different n-6/n-3 pufa ratios change stress-inducible cell signaling. garden dormice (eliomys quercinus) were fed one of three diets designed with different ratios of ...202032528974
morphological divergence in giant fossil dormice.insular gigantism-evolutionary increases in body size from small-bodied mainland ancestors-is a conceptually significant, but poorly studied, evolutionary phenomenon. gigantism is widespread on mediterranean islands, particularly among fossil and extant dormice. these include an extant giant population of eliomys quercinus on formentera, the giant balearic genus †hypnomys and the exceptionally large †leithia melitensis of pleistocene sicily. we quantified patterns of cranial and mandibular shape ...202033143584
