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...

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...

Monoidal width was recently introduced by the authors as a measure of complexity decomposing morphisms in monoidal categories. We have shown that category cospans graphs, and its variants can be used to capture tree width, path branch width. In this paper we study matrices, an extension different open where connectivity information is handled with matrix algebra graphs are composed along edges ...

Dendroclimatology offers the unique opportunity to reconstruct past climate at annual resolution and wood from historical buildings can be used extend such information back in time up several millennia. However, varying often unclear origin of timbers affects sensitivity individual tree-ring samples. Here, we compare width density 143 living larch (Larix decidua Mill.) trees seven sites along a...

Wildfire number and burned area temporal dynamics within all of Siberia and along a south-north transect in central Siberia (45 ̋–73 ̋ N) were studied based on NOAA/AVHRR (National Oceanic and Atmospheric Administration/ Advanced Very High Resolution Radiometer) and Terra/MODIS (Moderate Resolution Imaging Spectroradiometer) data and field measurements for the period 1996–2015. In addition, fire ...
