建立和保持各种文化体系和机构从而保证人们适当的生活水平的同时保持森林生态系统及其生物多样性,是人们在目前及即将来临的世纪中所面临的一个巨大挑战。本文叙述了厄瓜多尔西北部地区一社团利用参与研究和环境教育来影响森林保护所进行的努力。在这一地区,低地农业的可持续性部分地依赖于丘陵森林的捕雾作用。Loma Alta的该社团了解和评价了这种捕雾作用,他们用他们自己的管理和决策系统来保护森林。这项研究工作是在关心热带森林保护的社会学家和自然学家普遍感兴趣的一项理论框架下进行的,它对于综合保护和发展结果给予了极大关注。

Background： Creep feeding is used to stimulate piglet post-weaning feed consumption.L-Glutamine（GLN） is an important source of fuel for intestinal epithelial *** objective of this study was to determine the impact of creep feeding and adding GLN or AminoGut（AG;containing glutamine ＋ glutamate） to pre-and post-weaning diets on pig performance and intestinal ***（N = 120） were allotted to four treatments during 14–21 d of lactation： 1） No creep feed（NC,n = 45）;2） creep fed control diet（CFCD,n = 45）;3） creep fed 1% GLN（CFGLN,n = 15）;4） creep fed.88% AG（CFAG,n = 15）.After weaning,the NC and CFCD groups were sub-divided into three groups（n = 15 each）,receiving either a control nursery diet（NC-CD,CFCD-CD） or a diet supplemented with either GLN（NC-GLN,CFCD-GLN） or with AG（NC-AG,CFCD-AG）.Litters that were creep fed with diets containing GLN or AG also were supplemented with those amino acids in the nursery diets（CFGLN-GLN,CFAG-AG）.Glutamine was added at 1% in all three post-weaning diet phases and AG was added at.88% in phase 1 and 2 and at.66% in phase ***： Feed conversion（feed/gain） showed means among treatment means close to significance（P = 0.056） and tukey＇s test for pairwise mean comparisons showed that Pigs in the CFGLN-GLN group had the best feed conversion（feed/gain） in the first three-week period post-weaning,exceeding（P = 0.044） controls（CFCD-CD） by 34%.the NC-AG group had（P = 0.02） the greatest feed intake in the last three week of the study,exceeding controls（CFCD-CD） by 12%.CFGLN-GLN,CFCD-GLN and sow reared（SR） pigs had the greatest（P = 0.049） villi height exceeding the CFCD-AG group by 18%,20% and 19% *** CFAG-AG group had the deepest（P = 0.001） crypts among all ***-GLN,CFCD-GLN and SR groups had the greatest（P = 0.001） number of cells proliferating（PCNA） exceeding those in the NC-CD group by 43%,54% and 63% *** reared pigs showed the greatest（P = 0.001） intestinal absorption capacity for xylose and
