2,4-D and Mycoleptodiscus terrestris for control of Eurasian Watermilfoil [PDF]

, 2005
Growth chamber studies were conducted to evaluate the impact of an indigenous fungal pathogen, Mycoleptodiscus terrestris (Gerd.) Ostazeski, and the herbicide 2,4-D applied alone and in combination with one another, on the growth of a nuisance ...

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Weed resistance diagnostic technologies to detect herbicide resistance in cerealgrowing areas. A review

Julius-Kühn-Archiv, 2012
Cereals are major crops used for food and feed. By 2050, the world population is expected to be close to 10 billion requiring a doubling of the food production from a fixed area of arable land.

Energized fencing reduces risk of American black bear (Ursus americanus) damage to bird feeders in Minnesota

Wildlife Society Bulletin, EarlyView.
Energized fences were effective at reducing black bear damage to bird feeders. The fences were 100% effective in a good natural bear food year and 77% effective in a poor natural bear food year. When bears breached the fences, the cause was typically poor electrical grounding.

Market regulation and productivity: The case of the Canadian Wheat Board

American Journal of Agricultural Economics, EarlyView.
Abstract Changes to regulatory environments influence firm‐level incentives, which can move the productivity frontier or reposition firms within an existing frontier. Estimating causal effects of policy changes requires a credible counterfactual for productivity in the absence of policy change.

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

Archaeometry, EarlyView.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...
