| 1 | Habitat specialization and phylogenetic structure of tree species in a coastal Brazilian white-sand forest显示文摘Aims The coastal Brazilian rainforest on white-sand(restinga)ranks among the most fragmented forest types in the tropics,owing to both the patchy distribution of sandy soils and widespread coastal development activities.Here we study the environmental and evolutionary determinants of a forest tree assemblage at a single restinga forest in Southeastern Brazil.We also explore the ability of competing hypotheses to explain the maintenance of species diversity in this forest type,which includes contrasting extremes of edaphic conditions associated with flooding stress.Methods The study was conducted in a white-sand forest permanent plot of 10.24 ha on the coastal plain of Southeastern Brazil.This plot was divided into 256 quadrats of 20×20 m,which were classified into two main edaphic habitats(flooded and drained).Trees with a diameter≥1 cm at breast height were identified.We assembled DNA sequence data for each of the 116 morphospecies recognized using two chloroplast markers(rbcL and matK).A phylogenetic tree was obtained using the maximum likelihood method,and a phylogenetic distance matrix was produced from an ultrametric tree.We analyzed similarity in floristic composition and structure between habitats and related them to cross-plot distances using permutation procedures.Null model torus shift simulations were performed to obtain a statistical significance level for habitat association for each species.The phylogenetic structure for the two habitats and for each 20×20 m quadrat was calculated using the mean phylogenetic distance weighted by species abundance and checked for significance using the standardized effect size generated by 5000 randomizations of phylogenetic tip labels.Important Findings Our results indicate that partitioning among edaphic habitats is important for explaining species distributions and coexistence in restinga forests.Species distributions within the plot were found to be non-random:there was greater floristic similarity within than between habitats,and>40%of the more abundant species were positively or negatively associated with at least one habitat.Patterns of habitat association were not independent of phylogenetic relatedness:the community was overdispersed with respect to space and habitat type.Closely related species tended to occur in different habitats,while neighboring trees tended to belong to more distantly related species.We conclude that habitat specialization is important for the coexistence of species in restinga forests and that habitat heterogeneity is therefore an essential factor in explaining the maintenance of diversity of this unique but fragile and threatened type of forest. | Alexandre A.de Oliveira Alberto Vicentini Jerome Chave Camila de T.Castanho Stuart J.Davies Adriana M.Z.Martini Renato A.F.Lima Ricardo R.Ribeiro Amaia Iribar Vinicius C.Souza | 2014 | Journal of Plant Ecology2014，7，2： | 4 |

| 9 | 限饲和再投喂对不同日龄鸡消化酶促反应的影响显示文摘试验旨在评价限饲和再投喂对两个不同日龄(7和35d)鸡酶活性和胃肠道器官重量的影响,在每种日龄下,鸡被限饲70%(30%自由采食)7d,然后自由采食3d。对照组自由采食10d。对胰腺中糜蛋白酶、胰蛋白酶、淀粉酶、脂肪酶活性和小肠中蔗糖酶、麦芽糖酶的活性进行分析,并且测量了腺胃、肌胃、小肠和大肠的重量。在14d,与对照组相比,限饲组的胰蛋白酶、淀粉酶活性均降低,但在42d,与对照组相比,限饲组蔗糖酶活性降低,表明限饲对酶活性的影响与日龄有关。限饲可以降低完成期(42d)各器官的重量。日龄35~42d的鸡,在再投喂后,器官重量增加,并且达到与对照组一致。在起始期(14d),腺胃和肌胃受限饲的影响很小,在完成期,肌胃也是受影响最小的器官,而小肠时受影响最严重。限饲的所有影响在恢复饲喂3d后被逆转,表明这种改变时快速且可逆的,并且限饲和再投喂与年龄有关。 | Cristiane R A Duarte Maria L M Vicentini P Pinheiro D F | 2014 | 饲料博览2014，0，10： | 1 |
