Liana effects on biomass dynamics strengthen during secondary forest succession.
Secondary forests are important carbon sinks, but their biomass dynamics vary markedly within and across landscapes. The biotic and abiotic drivers of this variation are still not well understood. We tested the effects of soil resource availability and competition by lianas on the biomass dynamics of young secondary tropical forests in Panama and assessed the extent to which liana effects were ...
متن کاملNitrification Potentials in Primary and Secondary Succession'
Potential nitrogen mineralization and nitrification were measured in soils from a primary successional sequence developed on sand dunes and from a secondary successional sequence on old fields. Potential nitrogen mineralization in soils from the primary sere increased through the first five stages and then leveled off. Nitrogen mineralization was relatively constant in soils from the secondary ...
متن کاملAntidunes on steep slopes
16 When increasing the rates of subcritical flow on gentle slopes, the bed successively produces 17 ripples, dunes and flat beds. Antidunes (defined here as all bed undulations for which the 18 surface gravity waves are in phase with the bed profile) appear only in high flow rates and 19 may be found in some extreme natural flow events. Inversely, on steep slopes flume 20 experiment (S≥1% appro...
متن کاملDeath on the slopes
Introduction The field of cell-death research has matured since pioneering discoveries showed that apoptosis is regulated genetically. Although many of the core caspase-signalling pathways are known, some of the most basic aspects of the biochemistry of mitochondrial apoptosis induction have remained elusive and are, in certain cases, controversial. Research on the metabolic dysfunction that oc...
متن کاملFactors Regulating Nitrification in Primary and Secondary Succession'
A six-point primary sere developed on sand dunes and a four-point secondary sere developed on old fields were studied to examine the regulation of nitrification in succession. Soils from sites along the seres were incubated in funnel-microlysimeters leached weekly with NH4CI and other nutrient solutions. Nitrate output in soils from the five youngest sites along the primary sere was rapidly sti...
