ABSTRACT The Eucalyptus variegated beetle (Paropsisterna cloelia) was established in New Zealand in 2016 and has caused substantial damage to selected host species. Previous field observations suggested that Pst. cloelia larvae may feed for a longer period during the year than the closely related Eucalyptus tortoise beetle (Paropsis charybdis), New ...

Effects of warming on plant uptake of post‐fire nitrogen in an arctic heath tundra
Summary Postfire nitrogen (N) becomes increasingly important with the rising frequency of fires in arctic tundra, and climate warming is expected to accelerate plant recovery following fire. However, how plants differ in utilizing this postfire N and how their postfire N uptake responds to warming remains unknown.

Desde 1988 el Instituto Forestal se encuentra ejecutando un completo estudio sobre el mejoramiento genético del género Eucalyptus. Uno de los objetivos de este estudio es la instalación de un huerto semillero de polinización directa. Para tal efecto es necesario un completo conocimiento del comportamiento fenológico de especies, procedencias y familias.

Conceptual representation of topographic gradients in Amazonian igapó forests. High, medium, and low igapós differ in elevation and flood duration, with low igapós experiencing the longest periods of inundation. Fungal mycelia and DNA symbols indicate sampling of root‐associated mycorrhizal communities across the gradient, used to assess the influence ...
