Relationship between deadwood structural diversity and carbon stock along environmental and disturbance gradients in Tropical dry forests

Folia Oecologica
Deadwood is a substantial component of forest ecosystems playing a vital role in maintaining ecosystem health and functioning. However, there is limited information on deadwood stand structure which encompasses attributes such as type, quantities and ...

Effects of tree fall on soil Collembola: Disentangling the role of gap formation and deadwood addition

Geoderma
Increased frequency of climate extremes causes large scale forest decline associated with gap formation and input of deadwood to the forest floor, which largely changes soil systems.

Deadwood in Italian forests according to National Forest Inventory results

Forest@, 2009
Deadwood plays a key role in the functioning and productivity of forest ecosystem and it is an important feature for assessing and monitoring biodiversity. The third Ministerial Conference on the Protection of Forests in Europe (MCPFE) has recognized the

Movement and habitat use of two aquatic turtles (\u3cem\u3eGraptemys geographic\u3c/em\u3e and \u3cem\u3eTrachemys scripta\u3c/em\u3e) in an urban landscape [PDF]

, 2008
Our study focuses on the spatial ecology and seasonal habitat use of two aquatic turtles in order to understand the manner in which upland habitat use by humans shapes the aquatic activity, movement, and habitat selection of these species in an urban ...

Models for SIMP dark matter and dark photon

, 2015
We give a review on the SIMP paradigm and discuss a consistent model for SIMP dark mesons in the context of a dark QCD with flavor symmetry. The $Z'$-portal interaction is introduced being compatible with stable dark mesons and is responsible for making ...

Drivers of wood‐inhabiting fungal diversity in European and Oriental beech forests

Ecology and Evolution
The hyperdiverse wood‐inhabiting fungi play a crucial role in the global carbon cycle, but often are threatened by deadwood removal, particularly in temperate forests dominated by European beech (Fagus sylvatica) and Oriental beech (Fagus orientalis). To

Spruce regeneration on woody microsites in a subalpine forest in the western Carpathians

Silva Fennica, 2015
The density of [L.] Karst. regeneration on different microsites, the quantity and quality of woody microsites, and seedling occurrence probability on stumps and fallen deadwood were studied in a subalpine forest that has been under protection for ...

Selection-Based Learning: The Coevolution Of Internal And External Selection In High-Velocity Environments [PDF]

, 2004
To understand the effects of selection on firm-level learning, this study synthesizes two contrasting views of evolution. Internal selection theorists view managers in multiproduct firms as the primary agents of evolutionary change because they decide ...

Unraveling the effect of environment and decomposer diversity on deadwood decomposition: lessons from a large-scale experiment

Ecological Processes
Background The decomposition of organic matter is among the most important ecosystem processes in forest ecosystems, regulating the carbon and nutrient cycle. However, our understanding about how direct (environment and decomposer diversity) and indirect
