Liming of acidic agricultural soils has been proposed as a strategy to mitigate nitrous oxide (N₂O) emissions, as increased soil pH reduces the N₂O/N₂ product ratio of denitrification. The capacity of different calcareous (calcite and dolomite) and siliceous minerals to increase soil pH and reduce N₂O emissions was assessed in a 2-year grassland field experiment. An associated pot experiment was conducted using homogenized field soils for controlling spatial soil variability. Nitrous oxide emissions were highly episodic with emission peaks in response to freezing–thawing and application of NPK fertilizer. Liming with dolomite caused a pH increase from 5.1 to 6.2 and reduced N₂O emissions by 30% and 60% after application of NPK fertilizer and freezing–thawing events, respectively. Over the course of the 2-year field trial, N₂O emissions were significantly lower in dolomite-limed than non-limed soil (p < .05), although this effect was variable over time. Unexpectedly, no significant reduction of N₂O emission was found in the calcite treatment, despite the largest pH increase in all tested minerals. We tentatively attribute this to increased N₂O production by overall increase in nitrogen turnover rates (both nitrification and denitrification) following rapid pH increase in the first year after liming. Siliceous materials showed little pH effect and had no significant effect on N₂O emissions probably because of their lower buffering capacity and lower cation content. In the pot experiment using soils taken from the field plots 3 years after liming and exposing them to natural freezing–thawing, both calcite (p < .01) and dolomite (p < .05) significantly reduced cumulative N₂O emission by 50% and 30%, respectively, relative to the non-limed control. These results demonstrate that the overall effect of liming is to reduce N₂O emission, although high lime doses may lead to a transiently enhanced emission.  相似文献

Sinusitis is a common disorder in horses and may result from trauma, dental diseases, or space-occupying lesions. Radiography can only provide a limited amount of information. Computed tomography (CT) has been documented as an alternative imaging method. Eighteen horses (mostly Warmblood) with signs of chronic sinusitis were examined preoperatively with CT to assist in diagnosis of the underlying cause. There was a group of common CT features in horses with dental disease and sinusitis. The first molar was the most frequently affected maxillary cheek tooth. Hypoattenuation of the cementum, destruction of the enamel, and filling of the infundibular cavity with gas were the most frequent CT findings associated with caries. Gas bubbles within the bulging root area or fragmentation of the root in combination with swelling of the adjacent sinus lining were the most important CT features of dental decay. CT findings associated with sinusitis included excessive thickening of the respiratory epithelium in the rostral maxillary sinus; the caudal maxillary sinus was less often involved. The infraorbital canal, the nasomaxillary duct, and the frontomaxillary aperture were usually involved. The maxillary bone, however, especially the facial crest, was involved in nearly every horse, being characterized by endosteal sclerosis, thickening, periosteal reaction, and deformation leading to facial swelling in chronic infections. CT images allowed identification of involvement of individual teeth more clearly to reveal the diseased one for treatment. Three-dimensional imaging allowed improved understanding of the extent and severity of the pathologic change.  相似文献   

Einfluss verschiedener Unterlagen auf vegetative und generative Parameter bei der Apfelsorte ‘Topaz’ unter biologischen Anbaubedingungen in Ostösterreich     

Andreas Spornberger  Elisabeth Schüller  Edina Vidéki  György Végvári 《Erwerbs-Obstbau》2018,60(3):231-238

In autumn 2008, in the research orchard of the University of Natural Resources and Life Sciences in Vienna, the apple cultivar ‘Topaz’ was planted on the rootstocks M9 (clone T337) with and without ‘Rubinola’ as interstem, M26, M7 grafted at 25?cm and at 55?cm respectively, M111 and ‘Bittenfelder seedling’, trained as spindles and tested for eight years according to organic production rules. The trees on seeding grew very vigorously, followed by MM111 and M7 normally grafted; the M7 highly grafted trees showed less vigor, comparable with M26, while the trees on M9 with and without interstem grew very weakly. Tree losses were only observed on M9 without interstem. The highest yields per hectare were found on M7 normally grafted, followed by M26, M7 highly grafted and M9 without interstem. M7 highly grafted showed the highest single fruit weights, followed by MM111, at the other end were M9 with and without interstem, and M26. The rootstock M7 grafted at 55?cm combines a medium growth with high yield and good fruit quality and therefore can be recommended for dry areas like our site. M9 without interstem showed a higher specific yield and fruit firmness after storage compared to the variant with interstem. Whether these advantages for ‘Topaz’ on M9 can be combined with a higher grafting height as effective preventive method to control Phytophthora cactorum, has to be examined in further research.  相似文献   

Adrenal gland disease in ferrets.     

Elisabeth Simone-Freilicher 《Veterinary Clinics of North America: Exotic Animal Practice》2008,11(1):125-37, vii

Adrenal gland disease in ferrets is unique to this species, with clinical signs and pathophysiology different from those seen in the dog. Its prevalence is increasing; 70% of pet ferrets in the United States were affected in 2003. The exact causes of the adrenal gland changes that lead to the disease are not known. Early oophorohysterectomies and neutering, combined with the artificially prolonged photoperiod experienced by indoor pet ferrets, and a possible genetic component, may be contributing factors. Signs of adrenal gland disease include progressive hair loss, pruritis, lethargy, atrophy, and, in female ferrets, vulvar swelling. An understanding of the signs and physiologic changes is necessary for diagnosis and treatment. A review of anatomy, physiology, and current surgical and medical options is presented.  相似文献

Use of field records and competition results in genetic evaluation of station performance tested Swedish Warmblood stallions     

Elisabeth Olsson  Anna Nsholm  Erling Strandberg  Jan Philipsson 《Livestock Science》2008,117(2-3):287-297

The main objective of this study was to investigate possibilities to increase accuracy in the selection and test of Swedish warmblood stallions by combining information from stallion performance tests (SPT) with information from competitions and riding horse quality tests (RHQT). Data on 801 stallions judged at the SPT 1979–2005 were used for the analyses, which also included about 14 900 horses from the RHQT, 26 800 horses with results in show jumping and 14 200 horses with results in dressage competitions.Heritability coefficients were on average 0.41 for individual gaits under rider and 0.36–0.65 for jumping traits in SPT. Heritabilities for competition traits were 0.17 for dressage and 0.27 for show jumping. The heritability for overall conformation in SPT was 0.25. Genetic correlations between stallion performance test traits and competition results were 0.44–0.77 for gaits and dressage, and 0.78–0.96 for jumping traits in SPT and show jumping. The genetic correlation between conformation and results in dressage competitions was 0.22.For stallions participating in SPT in 2004 and 2005 accuracy increased when evaluating stallions by adding information from relatives that have taken part in RHQT and competitions. For show jumping accuracy changed from 0.60 to 0.68 for stallions born in Sweden, an increase with 13%, when information from RHQT and competitions in show jumping were used. For stallions born in a foreign country, the corresponding figure was, 5%, lower. For dressage the information from RHQT and competition results in dressage changed the accuracy from 0.41 to 0.55, an increase with 34%, for stallions born in Sweden. The improvement in accuracy for imported stallions was 11%.  相似文献   

Giardia duodenalis in small animals and their owners in Germany: A pilot study

Giardia duodenalis is a relevant gastrointestinal protozoan pathogen of humans and animals. This species complex consists of eight genetically different assemblages. Assemblages A and B are pathogenic to humans and pets, thus confer zoonotic potential. The risk of zoonotic transmission has been controversially discussed. The aim of this monocentric cross‐sectional pilot study was to investigate G. duodenalis assemblages in humans and pets living in common households in Berlin/Brandenburg (Germany). Samples from dogs, cats and humans sharing the same households were screened for Giardia infection by antigen‐detecting assays. All human samples were additionally analysed by a Giardia‐specific qPCR. Cyst quantification and sequences of different gene loci (triosephosphate isomerase (tpi), glutamate dehydrogenase (gdh), β‐giardin (bg) and for dogs SSUrDNA) were analysed. A total of 38 households (31 households with dogs and seven with cats) with 69 human individuals participated in the study. Initial antigen‐detecting assays revealed Giardia‐positive results for 13 (39%) canine, one (14%) feline and one human sample. Reanalysis of the human samples by qPCR revealed two more positive specimens (4%). Two of these three samples were identified as assemblage B at all tested loci. Success rate of assemblage typing for pet samples was generally low and comprised mainly the SSUrDNA locus only. Overall, six of 13 Giardia‐positive canine samples were typable (2× A, 1× co‐infection: A and B, 1× C; 2× D). One pair of samples (dog and human) from the same household had a similar but not identical assemblage B sequence at tpi locus. Assemblage A was also detected in the dog specimen, which hampered sequence analysis. In conclusion, although exhibiting limitations due to the sample size, our study highlights the need for better and standardized typing tools to distinguish G. duodenalis strains with higher resolution in order to perform proper case–control studies for a realistic estimation of zoonotic risk.  相似文献
