Local sub‐population dynamics of a central European grey partridge meta‐population support large‐scale conservation approach to halt its ongoing decline

open access: yesWildlife Biology, EarlyView.
Many farmland birds such as the grey partridge Perdix perdix are experiencing sharp declines across Europe, which can lead to fragmentation and increasing isolation of local populations. Understanding the population dynamics of these local populations is becoming increasingly important for effective conservation efforts.

Fearfulness of geese and swans on cropland in winter: a multi‐species flight initiation distance approach

open access: yesWildlife Biology, EarlyView.
Geese and swans are focal species in conservation and in management aimed at reducing crop damage. In the former disturbance should be minimized, and in the latter it is important to know how different species react to scaring activities. Previous research about trade‐off between predation risk and foraging in birds often uses ‘flight initiation ...

Assessing Closed Hydroponic Subsystems for Batavia Lettuce Growth Under Different Planting Densities

open access: yesWorld Water Policy, EarlyView.
ABSTRACT Hydroponic systems have the potential to be sustainable and alternative methods for food production that confer advantages of high production and better control of growth. However, only a few studies have focused on leafy vegetable growth in different subsystems and environmental variables.

Sugar Beet Demonstration

open access: yes, 2009
The sugar beet ( Beta vulgaris ) demonstration was conducted in response to the planned construction of an ethanol plant in Muscatine. Instead of corn, the facility will use sugarbased feedstocks such as molasses and, hopefully, locally grown crops like sugar beets.
