Abiotic factors and autumn migration phenology of Woodcock (Scolopax rusticola Linnaeus, 1758, Charadriiformes: Scolopacidae) in a Mediterranean area
(2013)This research examines the relationship of abiotic factors to the autumn number increase of Eurasian woodcocks in a wintering area. Data on the number of woodcocks spotted per day using dogs for 12 years in an area of ... -
Analysis of MC1R genetic variation in Lepus species in Mediterranean refugia
(2012)A study on the inter- and intraspecies variation of MC1R gene was performed in Lepus species inhabiting the Mediterranean basin (L granatansis, L europaeus, L. corsicanus, L castroviejoi and L mediterraneus) and their ... -
Assessing the effects of environmental factors on the presence and density of three shrike species in a continental and a coastal area of central Greece
(2014)This study was conducted in two different Mediterranean areas of central Greece and aimed at (i) comparing the breeding density and frequency of occurrence of shrike species between these two areas, (ii) identifying the ... -
Chromosome analyses challenge the taxonomic position of Augosoma centaurus Fabricius, 1775 (Coleoptera: Scarabaeidae: Dynastinae) and the separation of Dynastini and Oryctini
(2013)Augosoma centaurus Fabricius, 1775 (Melolonthidae: Dynastinae), one of the largest Scarabaeoid beetles of the Ethiopian Region, is classified in the tribe Dynastini MacLeay, 1819, principally on the basis of morphological ... -
Comparative methodology for the detection and differentiation of circulating microfilariae of Dirofilaria immitis in the dog
(2004)The sensitivities of the Knott's test (four 20-mul sediment aliquots), quantitative buffy coat capillary tube method (QBC tube, 111 mul of whole blood) and direct blood smear (DBS, 20 mul of whole blood) were evaluated for ... -
Detection of hybrids between wild boars (Sus scrofa scrofa) and domestic pigs (Sus scrofa f. domestica) in Greece, using the PCR-RFLP method on melanocortin-1 receptor (MC1R) mutations
(2010)The melanocortin-1 receptor (MC1R) regulates melanogenesis in mammals within the mammalian melanocyte and the hair follicle. Common variations (polymorph isms) in the MC1R gene are associated with normal differences in ... -
Dual reproductive cost of aging in male medflies: Dramatic decrease in mating competitiveness and gradual reduction in mating performance
(2011)Although age-based effects on the reproductive success of males have been reported in several animal taxa the cost of aging on male mating success in lekking species has not been fully explored. We used the Mediterranean ... -
EDITORIAL NOTE ON WEIGHT-LENGTH RELATIONS OF FISHES
(2011)Weight-length relations of fishes are useful for estimation of biomass from length observations, e. g., in fisheries or conservation research. Here we provide some guidance to authors of such papers, in order to facilitate ... -
Effect of plasmin, plasminogen activators and a plasmin inhibitor on bovine in vitro embryo production
(2008)In the present study, four experiments were conducted to investigate the possible effects of plasminogen activators (urokinase-type plasminogen activator (u-PA) and tissue-type plasminogen activator (t-PA)), plasmin, and ... -
The effects of farming practices on earthworm dynamics in olive groves of central Greece (Oligochaeta)
(2012)We compared species richness, species composition, density and biomass of earthworm communities in organically and conventionally managed olive groves in central Greece. Earthworm biomass and density was significantly ... -
Evidence for European brown hare syndrome virus introduction with translocated brown hares (Lepus europaeus): implications for management of restocking operations
(2013)Context. Criticisms of wildlife restocking operations typically focus on concerns that translocations can lead to the introduction of pathogens, and risk the integrity of locally adapted genetic diversity. Restocking ... -
Exposure of Eurasian magpies and turtle doves to West Nile virus during a major human outbreak, Greece, 2011
(2012)A major number of West Nile virus (WNV) infections in humans occurred in 2010 in northern Greece, with 262 laboratory confirmed cases. In 2011, fewer cases were reported, but the pattern was more dispersed throughout the ... -
Fractures combination of the proximal antebrachium in an immature dog that resembles Monteggia fracture
(2006)A 5-month-old German shepherd dog with a combination of a proximal radial physeal fracture and a proximal ulnar diaphyseal comminuted fracture, with cranial displacement of their distal fragment, was presented. This fractures ... -
'Freedom from hunger' and preventing obesity: the animal welfare implications of reducing food quantity or quality
(2009)In animals, including humans, free access to high-quality (generally energy-dense) food can result in obesity, leading to physiological and health problems. Consequently, various captive animals, including laboratory and ... -
Helminth burden in stray cats from Thessaloniki, Greece
(2014)To get an overview on the prevalence of intestinal helminths, between 2010 and 2012, fecal samples from 215 stray cats from area of Thessaloniki, Greece, were tested by coprological methods. From the total number of fecal ... -
Identifying newly spawned female sardines by means of common fisheries data
(2004)In the present study we provide an alternative to histology means of discerning newly spawned female sardines, i.e., females with intact postovulatory follicles, by means of common fisheries data like sample sex ratio, ... -
Luteal stage dependence of pituitary response to gonadotrophin-releasing hormone in cyclic dairy ewes subjected to synchronisation of ovulation
(2005)Possible hormonal aberrations precluding conception or maintenance of pregnancy in dairy ewes subjected to ovulation synchronisation were investigated in this study. The pituitary response to exogenous gonadotrophin-releasing ... -
