Soil Seed Banks in European Grasslands: Does Land Use Affect Regeneration Perspectives?

The Journal of Applied Ecology, 1997
Summary 1. Soil seed banks of 38 grassland sites in western Europe were sampled and species composition was determined. All sites differed in geographical region, soil type and intensity of management. 2. Relationships between the composition of the seed bank, the established vegetation, and soil and management parameters were analysed using ...

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change

European Policy Analysis, EarlyView.
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled

The function of phytogenic mounds in the accumulation and conservation of soil seed banks in semiarid areas with water erosion

Frontiers in Environmental Science
BackgroundPhytogenic mounds are a type of microtopography formed under perennial plants canopies in water erosion areas. However, the function of phytogenic mounds in seed assemblages and their ecological consequences remain poorly understood in semiarid

Beeinflussung der generativen Vermehrung von Rumex obtusifolius durch produktionstechnische Maßnahmen [PDF]

, 2005
Rumex obtusifolius produces a large number of long living seeds. Therefore, all means to reduce seed production or establishment of seedlings from seeds are impor-tant.

Life cycle assessment of biofuels from Jatropha curcas in West Africa: a field study [PDF]

, 2009
In recent years, liquid biofuels for transport have benefited from significant political support due to their potential role in curbing climate change and reducing our dependence on fossil fuels.

Precision planter monitoring system based on mobile communication network

IET Networks, EarlyView., 2022
Abstract Sowing is an important link in agricultural production and the basis for ensuring high yields and bumper harvests. Agriculture requires precision plows with good performance and stable work. However, the seeding process is in a completely closed state, and the operator relies mainly on experience to judge the operating state and performance of

Fact sheet: Soil seed banks in a mature coniferous forest landscape: Dominance of native perennials and low spatial variability [PDF]

, 2014
Viable seeds stored in soil (soil seed banks) are important features of plant communities that contribute to site potential for restoration and recovery from disturbance (events that disrupt an ecosystem such as fire or logging).
