Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2018 Spatial variations in yield occur in all agricultural fields to some degree. Knowledge of the reasons for these variations, especially temporally stable yield patterns, is needed in order to improve productivity by changing production methods or inputs ...

Does residence time affect responses of alien species richness to environmental and spatial processes? [PDF]
, 2012 One of the most robust emerging generalisations in invasion biology is that the probability of invasion increases with the time since introduction (residence time). We analysed the spatial distribution of alien vascular plant species in a region of north-

Seasonal variation of underwater sound propagation in the Beibu Gulf
Frontiers in Marine ScienceVariations in the underwater sound speed significantly influence sound propagation in the ocean, thereby impacting both underwater navigation systems and a substantial portion of marine organisms reliant on sound. This study utilizes cruise data from the

Addressing spatial variability in provenance experiments exemplified in two trials with black spruce
Journal of Forest Science, 2007 Two exemplary black spruce (Picea mariana [Mill.] B.S.P.) provenance trials were analyzed using traditional and spatial techniques. The objective was to find out possible differences between these approaches in terms of both the resulting fit-statistics ...

Forecasting storm tides during strong typhoons using artificial intelligence and a physical model
Frontiers in Marine ScienceThe combination of typhoon-induced storm surges and astronomical tides can result in extreme seawater levels and disastrous effects on coastal socioeconomic systems. The construction of an appropriate wind field has consistently been a challenge in storm

Consistency of spatial dependence of soil chemical properties in two fields: a geostatistical study
Plant, Soil and Environment, 2004 This study examined consistency of spatial variation of plant-available soil nutrients P, K, Mg and soil pH in two fields of an area of 54 and67.5 ha(haplic Luvisol and luvic Chernozem) in the region of Český Brod (Central Bohemia).
