This line
emerges from the two previous ones and it is aimed at
applying them to the specific case of forest ecosystems.
The combination of ecophysiology with demography and
reproductive biology, among other aspects, is facilitated
by the thematic network GLOBIMED. Main current topics
of interest are:
Available
radiation in the understory of a Holm oak (Quercus ilex)
forest mixed with rockrose (Cistus ladanifer) in El
Pardo (Madrid). Mean radiation in the understory was
50% of that in the open, but the remarkable spatial
heterogeneity led to zones receiving more than 80% and
other less than 20% within a few meters apart from each
other. The map is 1 hectare an was made interpolating
from more than 900 hemispherical photographs taken in
a regular messh of 1 m2.
Light
as an ecological factor. Effect of irradiance
on forest flora and fauna.
Characteristics of light in Iberian
forest understories.
The ecological role of environmental
heterogeneity. Implications for species
coexistence.
Influence of forest management on environmental
heterogeneity, particularly in traditionally
managed systems such as oak forests
and woodlands.
Rasgos funcionales
de especies y poblaciones invasoras.
Influencia de
la gestión del bosque, especialmente
del abandono de formaciones muy intervenidas
(alcornocales, encinares), en la heterogeneidad
ambiental.
Effects of the
interactions between factors on understory
communities with emphasis on drought and
shade.
