Reed canary grass observations of effects on crop stand and fibre quality caused by infestation of Epicalamus phalaridis

Agricultural and Food Science, 2008
A severe infestation of the gall midge Epicalamus phalaridis (Diptera: Cecidomyiidae)occurred in a field of reed canary grass, Phalaris arundinacea in northern Sweden.

Genetic Variability and Its Implications on Early Generation Sorghum Lines Selection for Yield, Yield Contributing Traits, and Resistance to Sorghum Midge

International Journal of Agronomy, 2018
Sorghum is the second most important cereal crop in Niger. The crop is grown in a wide range of ecological environments in the country. However, sorghum grain yield in Niger is limited by both abiotic and biotic constraints.

Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

River Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

River Research and Applications, EarlyView.
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

Effects of Engineered Dam Releases on Benthic Assemblages During Drought and Comparison With Unregulated Reaches

River Research and Applications, EarlyView.
ABSTRACT River regulation following damming is often associated with deleterious downstream effects, in large part due to reduced total discharge and disruption of seasonal flooding. These effects would be expected to be exacerbated by drought, particularly extended drought.

A systematic review using the Theoretical Domains Framework to identify barriers and facilitators to the adoption of prescribing guidelines

International Journal of Pharmacy Practice, EarlyView., 2020
Abstract Objectives Evidence‐based guidelines have the potential to reduce variation and increase prescribing quality. Identifying the key determinants to their uptake, using a theory‐based approach, may assist in the design of successful interventions to increase their adoption into practice.

Predicting the expansion of Gephyraulus lycantha as a key pest of goji berry in China under climate change

Frontiers in Plant Science
BackgroundThe gall midge, Gephyraulus lycantha Jiao & Kolesik (Diptera: Cecidomyiidae), causes abnormal enlargement of goji berry, Lycium barbarum L, buds during its larval stage, forming galls and resulting in a significantly decrease in yield in ...

The History and Ideas of George Herbert Mead's Pragmatism and Its Relevance for Operational Research and Systems Thinkers

Systems Research and Behavioral Science, EarlyView.
ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without
