Effect of overstory tree species diversity and composition on ground foraging ants (Hymenoptera: Formicidae) in timber plantations in Ghana [PDF]

International Journal of Biodiversity Science, Ecosystem Services & Management, 2016
ABSTRACTPlantation forests are becoming an increasingly important component of the world’s forested ecosystem. However, relatively little is known about how forest plantation management, overstory tree species composition and diversity impact biodiversity of nontree components of the forest.

Habitat characteristics and climatic factors influence microhabitat selection and arthropod community structure in a globally rare central Appalachian shale barren

Ecology and Evolution, 2021
The central Appalachian shale barrens, a globally unique habitat type restricted to the eastern United States, presents an insular and physiologically stressful environment with sparse vegetation and extreme ground surface and air temperatures.

Small-scale variation of vegetation in a mixed forest understorey is partly controlled by the effect of overstory composition on litter accumulation [PDF]

Journal of Forest Research, 2011
We investigated how richness and composition of vascular plant species in the understory of a mixed hardwood forest stand varied with respect to the abundance and composition of the overstory. The stand is in central Spain and represents the southernmost range of distribution of several tree and herbaceous species in Europe.

Fire Season, Overstory Density and Groundcover Composition Affect Understory Hardwood Sprout Demography in Longleaf Pine Woodlands [PDF]

Forests, 2018
Seasonal timing of prescribed fire and alterations to the structure and composition of fuels in savannas and woodlands can release understory hardwoods, potentially resulting in a global increase of closed-canopy forest and a loss of biodiversity. We hypothesized that growing-season fire, high overstory density, and wiregrass presence in longleaf pine ...

Influence of forest composition on understory cover in boreal mixedwood forests of western Quebec

Silva Fennica, 2002
Forest overstory composition influences both light and nutrient availability in the mixed boreal forest. The influence of stand composition on understory cover and biomass was investigated on two soil types (clay and till deposits).

Fire-induced shifts in overstory tree species composition and associated understory plant composition in Glacier National Park, Montana

Plant Ecology, 2012
In Rocky Mountain forests, fire can act as a mechanism of change in plant community composition if postfire conditions favor establishment of species other than those that dominated prefire tree communities. We sampled pre and postfire overstory and postfire understory species following recent (1988–2006) stand-replacing fires in Glacier National Park (

The Effects of Environmental Features and Overstory Composition on the Understory Species Assemblage in Sub-Mediterranean Coppiced Woods: Implications for a Sustainable Forest Management [PDF]

Polish Journal of Ecology, 2017
Understanding the relationship among environmental factors, overstory and understory is a key step for the improvement of sustainable forest management. Our aim was to understand how environmental features (topographic factors) and overstory (tree species) composition affect understory (shrub and herb species) assemblage in sub-Mediterranean coppiced ...

Facilitation differentially affects competitive responses of aspen and subalpine fir through stages of stand development

Ecosphere, 2022
Spatial interactions between trees influence forest community succession. The objective of this study was to investigate how shifts in forest composition and proximity between tree species affect stand development over time in mixed forest systems.

Red-cockaded woodpecker habitat characteristics associated with partial brood loss in the Upper East Gulf Coastal Plain, USA

Endangered Species Research, 2023
Some red-cockaded woodpecker (RCW) Dryobates borealis populations remain understudied. This is notable because management that incorporates population demographics and site characteristics may benefit RCW recovery.

Understory floristic composition of planted western white pine stands in the northern Rocky Mountains

Forest Ecosystems
Understory plants are an integral part of forests, serving a variety of functions that help maintain healthy ecosystems. The structure and composition of the understory are influenced by numerous biotic and abiotic factors, with light being critical. The
