Physical Damage in Relation to Carbon Allocation Strategies of
Tropical Forest Tree Saplings1
ABSTRACT
We show that tropical forest tree saplings with greater belowground carbon allocation have more breakage scars along
their stems. We suggest the existence of alternative carbon allocation strategies in relation to physical damage in the
forest understorey. ``Tolerators'' allocate more belowground, have enhanced resprouting ability and slower aboveground
growth, whereas ``escapers'' allocate less belowground, are not well prepared for recovering from damage, but grow
fast enough to escape from the damage-susceptible size class.
RESUMEN
Brinzales de a´rboles tropicales que asignan mayor cantidad de carbono bajo el suelo muestran ma´s cicatrices de fractura
en sus tallos. Sugerimos la existencia de estrategias alternativas de asignacio´n de carbono en respuesta a dan~o fi´sico en
el sotobosque: los ``tolerantes'' asignan mayor cantidad de carbono bajo el suelo, tienen mayor capacidad para rebrotar
y su crecimiento ae´reo es lento; los ``escapistas'' asignan menor cantidad de carbono bajo el suelo y no esta´n bien
preparados para recuperarse despue´s de ocurrido un dan~o, pero crecen lo suficientemente ra´pido para escapar de la
clase diame´trica ma´s susceptible a dan~os.
