| effect of initial soil properties on six-year growth of 15 tree species in tropical restoration plantings. | in restoration plantings in degraded pastures, initial soil nutrient status may lead to differential growth of tropical tree species with diverse life history attributes and capacity for n2 fixation. in 2006, we planted 1,440 seedlings of 15 native tree species in 16 fenced plots (30 × 30 m) in a 60-year-old pasture in los tuxtlas, veracruz, mexico, in two planting combinations. in the first year, we evaluated bulk density, ph, the concentration of organic carbon (c), total nitrogen (n), ammonia ... | 2016 | 28035260 |
| effects of leaf litter species on macroinvertebrate community properties and mosquito yield in neotropical tree hole microcosms. | detritus quality and quantity affect macroinvertebrate productivity and distribution in many freshwater ecosystems. this study experimentally investigated the effects of leaf litter from ceiba pentandra, dipteryx panamensis, ficus yoponensis, and platypodium elegans on macroinvertebrate species composition, richness, and abundance in artificial water-filled tree holes in a lowland moist forest of panama. species composition was similar among treatments, but species richness and longevity differe ... | 1999 | 28308046 |
| early recruitment dynamics in tropical restoration. | unassisted secondary succession in abandoned tropical pastures often results in species-poor forests of pioneer trees that persist for decades. we characterize recruitment rates of woody vegetation in planting treatments during the first 60 months of experimental restoration on thin, eroded soils at los tuxtlas, southern mexico. we test the hypothesis that recruitment of later-successional trees is greater in fenced plots planted with native trees than in fenced controls that simulate natural su ... | 2013 | 23967580 |
