Drought-induced mortality affects understory vegetation: release after death
(Springer Tokyo, 2012-07)
In recent decades, severe droughts have become an important cause of canopy disturbance in forests, and have shown potential to cause rapid and pronounced vegetation shifts. Under dead canopy, undamaged understory could ...
The role of the understory on the abundance, movement and survival of Ceroglossus chilensis in pine plantations: an experimental test
(Springer, 2015)
Tree plantations may play a role in the conservation of global forest biodiversity. At the landscape scale, plantations with a complex understory may provide surrogate habitats for forest-dwelling organisms. This was tested ...
Converting clear cutting into a less hostile habitat: The importance of understory for the abundance and movement of the Chestnut-throated Huet-Huet (Pteroptochos castaneus: Rhinocryptidae)
(Elsevier, 2017)
Sustainable forest management of commercial monoculture plantations may be difficult to achieve in plantations of Monterrey pine because these commercial monocultures are managed under a clear cutting system, where the ...
Accompanying vegetation in young Pinus radiata plantations enhances recolonization by Ceroglossus chilensis (Coleoptera: Carabidae) after clearcutting
(Springer, 2017)
The replacement of native forests by Pinus radiata plantations modifies habitat availability and quality for wildlife, constituting a threat to species survival. However, the presence of understory in mature pine plantations ...
Characterization of Nothofagus pumilio (Lenga) understory in managed and unmanaged forests of central Patagonia, Argentina
(Soc Amer Foresters, 2017-04)
In managed forests, biodiversity conservation is crucial for the sustainable use of ecosystem resources. In the Patagonian-Andes forests of Argentina, lenga (Nothofagus pumilio) is the most important native tree because ...
Two bromeliad species with contrasting functional traits partition the understory space in a South American xerophytic forest: correlative evidence of environmental control and limited dispersal
(Springer, 2014-02)
We examined the spatial distribution of two bromeliad species with contrasting functional traits in the understory of a xerophytic South American Chaco forest. Aechmea distichantha is a facultative terrestrial species with ...
Thinning of loblolly pine plantations in subtropical Argentina: Impact on microclimate and understory vegetation
(Elsevier Science, 2017-01)
During the last three decades, the area dedicated to tree plantations in northeast of Argentina has increased five-fold at the expense of the native semideciduous Atlantic Forest. Silvicultural practices such as thinning ...
Anthropogenic thermal gradient in managed landscapes determines physiological performance and explains the edge-biased distribution of ectothermic arthropods
(Elsevier B.V., 2019)
The intensive management of tree plantations has replaced and fragmented native forests worldwide. A direct consequence of this activity is the creation of new edges, which generate changes in microclimatic conditions in ...
Impact of introduced herbivores on understory vegetation along a regional moisture gradient in Patagonian beech forests
(Elsevier Science, 2016-04)
Introduced ungulates can alter understory structure and composition posing a serious threat to forest biodiversity. Yet how large-herbivore impacts in forested regions vary along major environmental gradients remains little ...
