Prevalence of hepatic lesions at post-mortem examination in dogs and association with pancreatitis     

Watson PJ  Roulois AJ  Scase TJ  Irvine R  Herrtage ME 《The Journal of small animal practice》2010,51(11):566-572

Objectives : To assess the prevalence of canine chronic hepatitis (CH) and other liver diseases in first opinion practice and identify associations with concurrent chronic pancreatitis (CP). Methods : One large section of left lateral lobe of liver was taken from 200 unselected canine post-mortem examinations from first opinion practices. Histological changes were categorised based on WSAVA criteria. Prevalence of CH and other liver diseases were calculated. Relative risks (RR) for liver histopathology in association with CP and for CH in different breeds were also calculated. Results : The prevalence of CH was 12%. Some breeds had an increased RR of CH, although sample sizes were small. Dogs with CP had an increased RR of reactive hepatitis but no significant association with the other liver diseases. Clinical Significance : CH is common in the first opinion dog population but less common than CP. CP was significantly associated with reactive hepatitis but not CH. Possible breed associations mirrored another recent UK study. Some dogs with CP may be erroneously diagnosed clinically as having CH on the basis of increased serum liver enzymes because of concurrent reactive hepatitis if the diagnosis is not confirmed histologically.  相似文献

A test of the association between Lake Habitat Quality Assessment and macroinvertebrate community structure     

Elaine McGoff  Kenneth Irvine 《水产资源保护:海洋与淡水生态系统》2009,19(5):520-533

• 1. Lake Habitat Survey (LHS) provides a standard method for characterizing the physical habitat of lakes and reservoirs, but has not been tested for its relevance to the composition and abundance of macroinvertebrates. This study investigated the relationship between the metrics used in LHS and components of macroinvertebrate communities found in the littoral zone of a shallow calcareous lake in the west of Ireland.
• 2. A scoring system, the Habitat Quality Assessment (HabQA), developed from the Lake Habitat Quality Assessment (LHQA) of the LHS, was used to assess the relationship between habitat quality based on physical structure within 10 LHS ‘habplots’ and metrics of the macroinvertebrate community.
• 3. Macroinvertebrate taxon richness, both of adults found in the riparian zone and larvae found in the littoral zone, correlated positively with the HabQA score. Macrophytes within the littoral zone, and complexity of riparian vegetation within the riparian zone, were particularly important in driving the HabQA score. While overall abundance of macroinvertebrates did not vary with HabQA score, that of particular genera did.
• 4. The HabQA score was a useful surrogate of taxon richness for adult and larval aquatic macroinvertebrates, suggesting that, in general, LHS provides a useful conservation assessment tool relevant for macroinvertebrates. However, in some circumstances, such as wave‐washed stony substrates devoid of macrophytes, the HabQA score may not capture the quality of a site for macroinvertebrates, and the importance of natural but low diversity sites should not be neglected in conservation assessment of lakes. Similarly, while the LHS method notes the presence of alien species, further work on how these could be incorporated into the method would be useful.
• 5. Reliance on a single, or overall combined, metric score across quality elements, whether based on biotic or structural assessment, has some potential limitations. It is clear that for conservation management a holistic assessment of naturalness, representativeness and species rarity needs to be made in conjunction with scoring systems.

Carbon dioxide and energy flux partitioning between the understorey and the overstorey of a maritime pine forest during a year with reduced soil water availability   总被引：1，自引：0，他引：1

Carbon dioxide, water vapour and energy fluxes were measured above and within a maritime pine forest during an atypical year with long-lasting reduced soil water availability. Energy balance closure was adequately good at both levels. As compared with what is usually observed at this site the ecosystem dissipated less energy via latent heat flux and more via sensible heat flux. The understorey canopy was responsible for a variable, significant component of the whole canopy fluxes of water vapour and carbon dioxide. The annual contribution of the understorey was 38% (154 mm) of the overall evaporation (399 mm) and 32% (89 mm) of the overall sensible heat flux (274 mm). The participation of the understorey reached 45% of the overall evaporation and 30% of the daytime overall assimilation during significant soil water deficit periods in summertime. Even during winter, understorey photosynthesis was consistent as it compensated soil and understorey respiration. The ecosystem behaved as a sink of carbon, with a negative annual carbon budget (−57 g C m⁻²). However, due to high soil water deficit, the annual ecosystem GPP was 40% less than usually observed at this site. This budget resulted from a sink of −131 g C m⁻² for the overstorey and a source of +74 g C m⁻² for the understorey. Moreover, on an annual basis the overstorey layer contributed to almost two-thirds of the ecosystem respiration. Finally, the effect of long-lasting soil water deficit on the maritime pine forest was found more important than the effect of the heat wave and drought of summer 2003.  相似文献   

Localized Enrichment of PCB Levels in Street Dust Due to Redistribution by Wind     

Irvine  K. N.  Loganathan  B. G. 《Water, air, and soil pollution》1998,105(3-4):603-615

As part of a project to identify PCB sources in combined sewer overflows discharging to the Buffalo River, NY, nine street and two unpaved aggregate parking lot dust and dirt samples were collected and analyzed for selected PCB congeners and total PCBs. Without exception, the dust and dirt samples had greater concentrations associated with the higher-chlorinated homologue groups. PCB-congeners 153, 138, 101, 118, and 180 contributed >50% of the total PCBs mass in each sample, suggesting contamination with Aroclors 1254 and 1260. Total PCB concentrations for the dust and dirt samples ranged between 90 and 1700 ng g^-1. Samples with the highest concentrations were located across the street and downwind from an industrial lot that had been remediated for PCB contamination in 1988. The industrial lot had been contaminated with Aroclors 1254 and 1260, indicating that contaminated soil had been locally redistributed through natural and vehicle-generated wind. Calculations based on the particle size of the street dust confirm the possibility of wind-induced redistribution. Street and aggregate lot dust and dirt potentially contribute to Buffalo River PCBs loadings through combined sewer overflows and stormwater runoff. Best management practices such as more frequent street sweeping may be useful in reducing these loadings.  相似文献
