Efectos de la fertilización sobre la producción de hojarasca de bosques post-minería del Chocó Biogeográfico

Colombia Forestal
Los nutrientes del suelo son considerados como factores limitantes de la productividad primaria neta (PPN) de los bosques tropicales. En este sentido, se ha planteado que, en etapas sucesionales iniciales, la PPN está limitada por N y, en etapas tardías,

Contenido de nutrientes en las raíces finas y el mantillo de rodales de Eucalyptus grandis de diferente edad en la Mesopotamia Argentina [PDF]

Bosque (Valdivia), 2013
SUMMARY Entre Rios province is an important center of Eucalyptus spp. plantations in Argentina. It was hypothesized that fine root biomass and litter mass increased with age increasing in plantations. Five, seven and seventeen year old stands of Eucalyptus grandis were sampled. All of them were first rotation stands. We estimated the mass of litter and

Institutional fit and policy design in water governance: Nebraska's Natural Resources Districts

Policy Studies Journal, Volume 52, Issue 4, Page 809-832, November 2024.
Abstract The extent to which rules in a governing arrangement addresses its local conditions is usually defined in the environmental governance literature as the problem of fit. Actors in governing arrangements with decision‐making authority are capable of choosing and designing specific policy tools in order to address specific policy problems.

Plant traits determine seed retention times in frugivorous birds: Implications for long‐distance seed dispersal

Functional Ecology, Volume 38, Issue 10, Page 2247-2260, October 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal by frugivorous animals is a key process for plant populations and communities. When frugivores consume fruits, seeds are temporarily retained inside their guts until seed deposition.

Differential responses of community‐level functional traits to mid‐ and late‐season experimental drought in a temperate grassland

Journal of Ecology, Volume 112, Issue 10, Page 2292-2306, October 2024.
These findings suggest that functional trait composition of grassland communities may shift under climate change‐induced drought, depending on the growing season timings. Trait‐based attempts to predict ecosystem functioning must account for such temporal variation in community trait values.
