Orthopterans are insects closely linked to vegetation as primary consumers as well as for other biological processes such as oviposition and development. This research aims to assess the effect of a revegetation program that began in 2007 in the compensation area linked to the construction of the Breña II dam on Orthopteran diversity within several different human-created and natural habitats (...

Canopy height data collected with an airborne laser scanner (ALS) flown across unmanaged parts of Canada’s boreal forest in the summer of 2010 were used—as stand-alone data—to derive a least-squares polynomial (LSPOL) between presumed post-fire recovered canopy heights and duration (in years) since fire (YSF). Flight lines of the >25,000-km ALS survey intersected 163 historic fires with a known...

This research explores urban growth based scenarios for the city of Nairobi using a cellular automata urban growth model (UGM). African cities have experienced rapid urbanization over the last decade due to increased population growth and high economic activities. We used multi-temporal Landsat imageries for 1976, 1986, 2000 and 2010 to investigate urban land-use changes in Nairobi. Our UGM use...

This paper describes an unmanaged 193Os-era pine-hardwood stand on ;I minor stream terrace in Ashley County, AR. Probably inventoried as a part of an early growth and yield study, the sample plot was approximately 3.2 ha in si,e and contained at least 21 tree species. Loblolly pine comprised 39.1 o/c of all stems, followed by willow oak (12.7(h), winged elm (9.6’S), sweetgum (7.8%), water oak (...

Abstract Tree regeneration is a key demographic process influencing long‐term forest dynamics. It driven by climate, disturbances, biotic factors and their interactions. Thus, predictions of tree are challenging due to complex feedbacks along the wide climatic gradients covered most species. The stress gradient hypothesis (SGH) provides framework for assessing such across species ranges, sugges...

The conversion of coniferous tree plantations towards natural self-regenerating forests is one the targets forestry in Europe and particularly desirable national parks. aim this study was to evaluate effectiveness different approaches (conducted once) on forest development man-made spruce plantations. We studied effects three distinct management options (partial-cutting [PC], clear-cutting with...

Habitat loss is considered a major threat for biodiversity. However, the scales on which its effects occur are still insufficiently understood, namely, amount of available habitat important species richness both local and landscape scales? We studied landscape-scale local-scale density deadwood-dependent lichens in Swedish boreal forests. Creation retention deadwood common practices to benefit ...

In intensive agricultural landscapes, restoration within farms could enhance biodiversity and ecosystem services such as pollination by native pollinators. Although governments and conservation groups are promoting small-scale restoration on working farms, there are few studies that assess whether these practices enhance pollinator communities in restored areas. Further, there is no information...
