Eucalyptus is one of the most promising genus because its fast-growing characteristics and hybridization among species can produce superior characteristics valuable to both the pulp and timber industries. To evaluate the possibility of using it for timber, growth characteristics and wood properties were investigated for three nine-year-old Eucalyptus species (E. urophylla, E. grandis, and E. pellita) planted for pulpwood in Indonesia. E. pellita showed superior growth characteristics and wood properties compared to the other two species. No negative correlation coefficients were observed between growth characteristics and wood properties in any of the species, indicating that improvement of wood properties might not reduce the growth characteristics. The hybrids from E. pellita and E. urophylla might produce a next generation with better growth characteristics, resistance to pests and diseases, tolerance to low soil fertility, and relatively good wood properties. In addition, based on the obtained results, hybridization between E. grandis and E. urophylla or E. pellita might improve the relatively low wood properties of E. grandis.","PeriodicalId":51890,"journal":{"name":"Tropics","volume":"26 1","pages":"59-69"},"PeriodicalIF":0.7,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3759/TROPICS.MS16-15","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70009774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the repeated fires distinctly decreased the number and basal area of culms per clump and the proportion of surviving culms throughout the study period, this bamboo species basically represents an adaptation to fire disturbance. A greater number of thin culms and many small branches produced by the fire-disturbed bamboos may have maximized photosynthesis with minimum allocation of photosynthate after they lose their aboveground parts. Further, the ratio of surviving clumps was higher at the unprotected site than at the protected site where selfthinning among clumps occurred. In contrast to these dynamic responses of bamboos against the fire disturbances, the number of individual clumps and their sizes remained smaller at the unprotected site than at the protected site. These results indicate that the intensity and frequency of fires primarily determine the dynamics of the bamboo population, having potential to alter the forest succession to either less or more bamboo dominating forest community. Further studies are required to elucidate the role of fire on the interaction between bamboo and tree species, specifically at the middle and matured stages of bamboo life history and along a gradient of fire regimes for better understanding assembly of the MDF community.","PeriodicalId":51890,"journal":{"name":"Tropics","volume":"298 1","pages":"37-48"},"PeriodicalIF":0.7,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3759/TROPICS.MS16-09","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70010074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant-ants on Macaranga myrmecophytes protect their host-plants against herbivores. Because interspecific differences in ant defense intensities among Macaranga myrmecophytes affect the host-plant use by herbivorous insects, they need to be studied to better understand the ecology and evolution of herbivores on Macaranga myrmecophytes. In this study, to examine whether larvae of a lycaenid species, Arhopala major, which potentially feeds on some Macaranga myrmecophytes, can be used for a bioassay that assesses relative ant aggressiveness towards general herbivores on Macaranga plants, we experimentally introduced A. major larvae onto leaves of three Macaranga myrmecophytic species. We measured (1) the time required for the first touch by plant-ants on an introduced larva and (2) the number of plant-ant workers aggregating 3 min after the first touch. The order of three Macaranga species in ant defense intensity, as estimated by the two measurements, corresponded with the results of previous studies investigating the interspecific differences in ant defense intensities using ant-exclusion experiments. This suggests that the bioassay using A. major larvae is valid for the assessment of relative intensities of ant defenses on Macaranga species. As time and labor cost are low and standardization is easier, compared with the other methods, such as ant-exclusion experiments, the bioassay tested in this study is practical for assessing ant defense intensities on Macaranga plants.","PeriodicalId":51890,"journal":{"name":"Tropics","volume":"25 1","pages":"101-106"},"PeriodicalIF":0.7,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3759/TROPICS.MS15-19","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70009787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that P addition reduced N2O emissions through stimulated microbial N immobilization and subsequent decrease in inorganic N resources for producing N2O. We prepared the following four experimental sets; high C (glucose 2000 μg C g soil ) and water-filled pore space (WFPS) 40 % (H40), low C (glucose 100 μg C g soil) and WFPS 40 % (L40), high C and WFPS 60 % (H60), and low C and WFPS 60 % (L60). Nitrogen (NH4NO3, 20 μg N g soil ) was also added to all soils. We prepared P-added soils (Ca(H2PO4)2, 20 μg P g soil ) and non-added control to test the effects of P addition on N2O emissions. Contrary to our hypothesis, P addition did not reduce N2O emissions, although soil microbial N immobilization was stimulated by P addition in soils with low C addition. Stimulated total N cycling by P addition probably offset the decrease in soil inorganic N. Meanwhile P addition reduced soil microbial biomass N (MBN) content in H60, where N2O emissions increased significantly by P addition. It was possible that the microbial growth reached its peak and started dying more quickly in P-added soils in H60 due to the favorable condition for microbes (higher C and water content). Thus we concluded that (i) P addition did not necessarily stimulate soil microbial N immobilization, and (ii) N2O emissions might not decrease even if P addition stimulated soil microbial N immobilization.","PeriodicalId":51890,"journal":{"name":"Tropics","volume":"25 1","pages":"117-125"},"PeriodicalIF":0.7,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3759/TROPICS.MS15-15","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70010194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because previous studies implied that they were caused by macrofauna, we conducted a field survey in a Malaysian lowland rainforest to examine whether increased soil respiration was induced by the activities of macrofauna such as termites, ants and earthworms. Soil respiration was measured in a grid system of 10 m intervals in a 1 ha plot. We measured soil respiration again three or four days after the first measurement to examine the spatiotemporal change in hot spots. After the second measurement, we excavated soil to a depth of 20 cm at the five points showing the highest soil respiration rates (hot spots) and their neighboring points as controls and visually searched for macrofauna. The average soil respiration for two measurements did not differ significantly (8.21 and 7.93 μmol CO2 m s, respectively). Four hot spots were revealed in each of the two measurements, but only one appeared in both measurements. Several ants (100-500 individuals, Lophomyrmex sp.) were observed in soil under soil respiration chamber areas at one hot spot and one control point, respectively. This suggests that the hot spots in the study site were not located near active nests or intensively active areas of macrofauna, and it is possible that the hot spots may represent the points of mass CO2flux transport events.","PeriodicalId":51890,"journal":{"name":"Tropics","volume":"25 1","pages":"77-83"},"PeriodicalIF":0.7,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3759/TROPICS.MS15-17","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70010219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dipterocarps in the two sites demonstrated the same values of crown position index (a surrogate of light conditions), implying that the greater tree growth in the volcanic site was associated with the greater soil nutrient availability, but not with light availability. On the other hand, relative growth rates of non-dipterocarps did not differ between the sites at all size classes despite the considerable differences in the soil nutrient concentrations, suggesting that factors other than N and P availabilities limit the growth of these trees. Contrary to growth rate, annual mortality rate was greater in the volcanic site at all size classes for all phylogenetic groups.
