Fourier analysis of historical NOAA time series data to estimate bimodal agriculture por Canisius, F., Turral, Hugh, David, S.

“…This result indicates that estimating bimodal agriculture area that is one of the main sources of information for irrigated area mapping at regional or global scale, with improved accuracy possible if greater spatial, temporal resolution is achieved, for instance from MODIS or SPOT vegetation time series NDVI data, combined with (1) an improved decision tree classification algorithm and (2) a greater precision and geographical distribution of ground-truth data. …”

Skattning av trädhöjd med hjälp av en ytmodell för laserdata por Lidén, Edvin, Söderberg, Johan

“…One theory to this result is that more laser points take directly on the ground and thus hit high undergrowth vegetation, protruding branches etc. in this areas whit more openings, which in turn lowers the surface models average height.…”

Differences in forest plant functional trait distributions across land-use and productivity gradients por Mayfield, M.M., Dwyer, J.M., Chalmandrier, L., Wells, J.A., Bonser, S.P., Catterall, C.P., DeClerck, Fabrice A.J., Yi Ding, Fraterrigo, J.M., Metcalfe, D.J., Queiroz, C., Vesk, P.A., Morgan, J.W.

“….• Methods: We examined how the variation and distribution of trait values for seven plant functional traits differ between reference natural forest and three types of land‐use conversion (pasture, old‐field, or “legacy” sites—regrowth following logging), landscape productivity (NPP) and vegetation strata (tree or non‐tree “understory”), in a meta‐analysis of studies from 15 landscapes across five continents.• Key results: Although trait variation often differed between land‐uses within a landscape, these patterns were rarely consistent across landscapes. …”
