Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

Drift of sprays, dusts, spores: Radioactive tracers used in determining distribution pattern of small airborne particles

California Agriculture, 1949
Spraying and dusting of agricultural crops with insecticides, fungicides, herbicides, hormones or fertilizers can be made more effective through accurate information as to the distribution pattern obtainable under various sets of conditions.

Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

Journal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Drift retardant chemical effects on spray droplet size, pattern and drift

, 1995
Objectives of this study were to determine the effects of various drift retardant chemicals on droplet size, spray pattern, and spray drift reduction of sprays from an XR 8004VH fan-pattern nozzle. Results indicated that, at recommended rates, Na1co-trol

Airborne Road Traffic Monitoring with Radar [PDF]

, 2007
To ensure mobility, future road traffic management needs actual and reliable information about the traffic over wide areas. Nowadays, outside of motorways the actual traffic situation is almost unknown due to the lack of sensor installations.

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

Bee pollen as functional food and environmental bioindicator: current evidence and future challenges

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Bee pollen (BP), a plant‐derived product collected by honey bees, is increasingly promoted as a functional food due to its content of proteins, essential amino acids, lipids, vitamins, minerals, and bioactive compounds such as polyphenols and flavonoids.
