| 1 | Silvicultural alternatives to conventional even-aged forest man-agement-what limits global adoption?显示文摘Background: The development of forestry as a scientific and management discipline over the last two centuries has mainly emphasized intensive management operations focused on increased commodity production, mostly wood. This 'conventional' forest management approach has typically favored production of even-aged, single-species stands. While alternative management regimes have generally received less attention, this has been changing over the last three decades, especially in countries with developed economies. Reasons for this change include a combination of new information and concerns about the ecological consequences of intensive forestry practices and a willingness on the part of many forest owners and society to embrace a wider set of management objectives. Alternative silvicultural approaches are characterized by a set of fundamental principles, including avoidance of clearcutting, an emphasis on structural diversity and small-scale variability, deployment of mixed species with natural regeneration,and avoidance of intensive site-preparation methods.Methods: Our compilation of the authors' experiences and perspectives from various parts of the world aims to initiate a larger discussion concerning the constraints to and the potential of adopting alternative silvicultural practices.Results: The results suggest that a wider adoption of alternative silvicultural practices is currently hindered by a suite of ecological, economic, logistical, informational, cultural, and historical constraints. Individual contexts display their own unique combinations and relative significance of these constraints, and accordingly, targeted efforts, such as regulations and incentives, may help to overcome specific challenges.Conclusions: In a broader context, we propose that less emphases on strict applications of principles and on stand structures might provide additional flexibility and facilitate the adoption of alternative silvicultural regimes in a broader set of circumstances. At the same time, the acceptance of alternative silvicultural systems as the 'preferred or default mode of management' wil necessitate and benefit from the continued development of the scientific basis and valuation of a variety of ecosystem goods and services. This publication is aimed to further the discussion in this context. | Klaus J Puettmann Scott McG Wilson Susan C Baker Pablo J Donoso Lars Dr?ssler Girma Amente Brian D Harvey Thomas Knoke Yuanchang Lu Susanna Nocentini Francis E Putz Toshiya Yoshida Jürgen Bauhus | 2015 | Forest Ecosystems2015，2，2： | 4 |
| 2 | Changes in the colon microbiota and intestinal cytokine gene expression following minimal intestinal surgery显示文摘AIM: To investigate the impact of minor abdominal surgery on the caecal microbial population and on markers of gut inflammation.METHODS: Four week old piglets were randomly allocated to a no-surgery 'control' group(n = 6) or a 'transection surgery' group(n = 5).During the transection surgery procedure, a conventional midline incision of the lower abdominal wall was made and the small intestine was transected at a site 225 cm proximal to the ileocaecal valve, a 2 cm segment was removed and the intestine was re-anastomosed.Piglets received a polymeric infant formula diet throughout the study period and were sacrificed at two weeks post-surgery.Clinical outcomes including weight, stool consistency and presence of stool fat globules were monitored.High throughput DNA sequencing of colonic content was used to detect surgery-relateddisturbances in microbial composition at phylum, family and genus level.Diversity and richness estimates were calculated for the control and minor surgery groups.As disturbances in the gut microbial community are linked to inflammation we compared the gene expression of key inflammatory cytokines(TNF, IL1 B, IL18, IL12, IL8, IL6 and IL10) in ileum, terminal ileum and colon mucosal extracts obtained from control and abdominal surgery groups at two weeks post-surgery.RESULTS: Changes in the relative abundance of bacterial species at family and genus level were confined to bacterial members of the Proteobacteria and Bacteroidetes phyla.Family level compositional shifts included a reduction in the relative abundance of Enterobacteriaceae(22.95 ± 5.27 vs 2.07 ± 0.72, P < 0.01), Bacteroidaceae(2.54 ± 0.56 vs 0.86 ± 0.43, P < 0.05) and Rhodospirillaceae(0.40 ± 0.14 vs 0.00 ± 0.00, P < 0.05) following transection surgery.Similarly, at the genus level, changes associated with transection surgery were restricted to members of the Proteobacteria and Bacteroidetes phyla and included decreased relative abundance of Enterobacteriaceae(29.20 ± 6.74 vs 2.88 ± 1.08, P < 0.01), Alistipes(4.82 ± 1.73 vs 0.18 ± 0.13, P < 0.05) and Thalassospira(0.53 ± 0.19 vs 0.00 ± 0.00, P < 0.05).Surgeryassociated microbial dysbiosis was accompanied by increased gene expression of markers of inflammation.Within the ileum IL6 expression was decreased(4.46 ± 1.60 vs 0.24 ± 0.06, P < 0.05) following transection surgery.In the terminal ileum, gene expression of TNF was decreased(1.51 ± 0.13 vs 0.80 ± 0.16, P < 0.01) and IL18(1.21 ± 0.18 vs 2.13 ± 0.24, P < 0.01), IL12(1.04 ± 0.16 vs 1.82 ± 0.32, P < 0.05) and IL10(1.04 ± 0.06 vs 1.43 ± 0.09, P < 0.01) gene expression increased following transection surgery.Within the colon, IL12(0.72 ± 0.13 vs 1.78 ± 0.28, P < 0.01) and IL10(0.98 ± 0.02 vs 1.95 ± 0.14, P < 0.01) gene expression were increased following transection surgery.CONCLUSION: This study suggests that minor abdominal surgery in infants, results in long-term alteration of the colonic microbial composition and persistent gastrointestinal inflammation. | Susan Lapthorne Julie E Bines Fiona Fouhy Nicole L Dellios Guineva Wilson Sarah L Thomas Michelle Scurr Catherine Stanton Paul D Cotter Prue M Pereira-Fantini | 2015 | World Journal of Gastroenterology2015，21，14： | 3 |
