Review of: Sumberg and Thompson (eds.). Contested Agronomy: Agricultural Research in a Changing World
(2013)
This review provides an overview and critical analysis of the book: Sumberg, J. and J Thompson. 2012. Contested Agronomy: Agricultural Research in a Changing World. NY: Taylor & Frances Books. It emphasizes the lead chapter, ...
Bioeconomics of managing the spread of exotic pest species with barrier zones
(Ecological Society of America, 1998-08)
Exotic pests are serious threats to North American ecosystems; thus, economic analysis of decisions about eradication, stopping, or slowing their spread may be critical to ecosystem management. We present a model to analyze ...
Temporal variation in end-member chemistry and its influence on runoff mixing patterns in a forested, Piedmont catchment
(American Geophysical Union, 2013-04-01)
Runoff mixing patterns for base flow and 42 storm events were investigated for a 3 year period (20082010) in a 12 ha forested catchment in the mid-Atlantic, Piedmont region of the USA. Eleven distinct runoff sources were ...
Identification and characterization of the first pectin methylesterase gene discovered in the root lesion nematode Pratylenchus penetrans
(Public Library of Science, 2019-02-22)
Similar to other plant-parasitic nematodes, root lesion nematodes possess an array of enzymes that are involved in the degradation of the plant cell wall. Here we report the identification of a gene encoding a cell ...
Transport of Magnesium by a Bacterial Nramp-Related Gene
(PLoS, 2014-06)
Magnesium is an essential divalent metal that serves many cellular functions. While most divalent cations are maintained at relatively low intracellular concentrations, magnesium is maintained at a higher level (similar ...
Long-term C-CO2 emissions and carbon crop residue mineralization in an oxisol under different tillage and crop rotation systems
(Sociedade Brasileira de Ciência do Solo, 2011)
Soil C-CO2 emissions are sensitive indicators of management system impacts on soil organic matter (SOM). The main soil C-CO2 sources at the soil-plant interface are the decomposition of crop residues, SOM turnover, and ...
Artificial topography changes the growth strategy of Spartina alterniflora, case study with wave exposure as a comparison
(Springer Nature, 2017-11-17)
This paper reports findings about the growth of Spartina alterniflora (Loisel.) near an engineered coastal protection defences to discover the potential influences on vegetation growth from the artificial topography. Impacts ...
Implementation of a multiprofessional, multicomponent delirium management guideline in two intensive care units, and its effect on patient outcomes and nurse workload: a pre-post design retrospective cohort study
(2020-01-21)
AIM OF THE STUDY: Delirium is a frequent intensive care unit (ICU) complication, affecting 26% to 80% of ICU patients, often with serious consequences. This study aimed to evaluate the effectiveness, costs and benefits of ...
Drip Chemigation of Insecticides as a Pest Management Tool in Vegetable Production
(Entomological Society of America, 2012-09-01)
Drip, or trickle, irrigation was used as early as the late 1800s, although it was not until the development of modern plastics during World War II that drip irrigation became economically possible. Developed initially to ...
Soil organic carbon dynamics and crop yield for different crop rotations in a degraded ferruginous tropical soil in a semi-arid region: a simulation approach
(2011-10)
In recent years, simulation models have been used as a complementary tool for research and for quantifying soil carbon sequestration under widely varying conditions. This has improved the understanding and prediction of ...
