The Sheffield Dynamic Global Vegetation Model has simulated the structure and net carbon exchange of vegetation at five sites along the Kalahari transect where there is a strong gradient in precipitation from 299 to 918mmyr . There has been a decline in precipitation of 8mmyr 1 along the whole of the transect since about 1970. Simulations of vegetation dynamics and structure indicate that this ...

Numerous applications of small footprint airborne lidar (light detection and ranging) have provided highly accurate results for estimating forest height. However, the associated acquisition cost remains high, which limits its use for wall-to-wall large area mapping. In this study, we developed a novel framework by integrating GEOBIA (GEOgraphic Object-Based Image Analysis), lidar transects and ...

The extent to which the leaves of woody dicots encode in their physiognomy the climatic conditions that exist during dormancy was tested by sampling 20 sites along an approximately west-east transect across European Russia, the Crimean Peninsula, Western Siberia, and central Eastern Siberia. This transect encompassed the most extreme mean annual temperature range recorded in the modern world wh...

The biocomplexity of sediment communities along a 120m transect near an arsenic-rich, shallow marine hydrothermal vent at Tutum Bay, Papua New Guinea was thoroughly examined. A count of macroand meiofaunal organisms was combined with bacterial and eukaryotic SSU rRNA gene surveys to assess biodiversity. Each site along the transect had distinct microbial communities. Near-vent sites were more s...

The Semarang City is a metropolitan city with such rapid development, so that it also affects several animals, one of which birds. One species bird can be found in various habitats the Genus Lonchura. This study aims to examine abundance and population distribution, feed preferences, availability food plants for munia urban, suburban, rural City. Data were collected using transect method, Visua...

WALKER, D. A. 1987. Height and growth rings of Salix lanata ssp. richardsonii along the coastal temperature gradient of northern Alaska. Can. J. Bot. 65: 988-993. Salix lanata ssp. richardsonii from open-tundra and streamside populations were studied at seven sites along a 100-km north-south transect following the Sagavanirktok River from the Alaskan arctic coast to the foothills of the Brooks ...

Due to climate change, the ranges of many North American tree species are expected to shift northward. Sugar maple (Acer saccharum Marshall) reaches its northern continuous distributional limit in northeastern North America at the transition between boreal mixed-wood and temperate deciduous forests. We hypothesized that marginal fragmented northern populations from the boreal mixed wood would h...

The effectiveness of lineand point-transect distance sampling methods was compared for estimating the density of a conspicuous endemic passerine, the North Island saddleback Philesturnus carunculatus rufusater, in two forest habitats on Tiritiri Matangi Island, Hauraki Gulf, New Zealand. The reference population abundance in each habitat was calculated through an intensive capture, colour-bandi...
