Invasive species can impose novel selection pressures on natives, such as toxins to which native taxa are not adapted. Native species may survive such invasions by evolving mechanisms to avoid toxin exposure or increase toxin tolerance. Red imported fire ants (Solenopsis invicta) employ an alkaloid-based venom to defend their colonies and capture prey. In this study we aim to characterize the s...

This article deals with the history, names and uses of the garden cress in Indian Medicine.

This article summarizes a 2000 study of school garden programs and their variation and the impact of such variation on 427 third-grade students’ sense of responsibility and attitudes toward science and the environment. A teacher questionnaire was developed to gain insight into how teachers use school gardens with their students and in their curriculum. The information gathered from 28 third-gra...

An environmental assessment of six scenarios for handling of garden waste in the Municipality of Aarhus (Denmark) was performed from a life cycle perspective by means of the LCA-model EASEWASTE. In the first (baseline) scenario, the current garden waste management system based on windrow composting was assessed, while in the other five scenarios alternative solutions including incineration and ...

This paper presents the development of a ‘Takt Time Control’ game and the use of this game in an experimental study. This study is meant to investigate the importance of the objective time fence (i.e. the time periods in which the player gets feedback) and the game complexity (i.e. variability within the system) on game performance. A major conclusion of the study is that it is important to gai...

The authors introduce the notion of crown-like orders and introduce powerful tools for counting the endomorphisms of orders of this type. r r r r r r r r @ @ @ @ @ @ 1 3 5 7 2 4 6 8 r r r r r r r r @ @ @ @ @ @ 3 3 3 3 3 3 3 1 3 5 7 2 4 6 8 Figure 1: The fence and crown of order 4 r r r r r r r r r r r r · · · · · · @ @ @ @ @ @ @ @ @ @ −5 −3 −1 1 3 5 −4 −2 0 2 4 6 Figure 2: The infinite fence F

We hypothesized that an exclusion fence could be devised to capitalize on traction limitations of the hooves of white-tailed deer (Odocoileus virginianus). Hexagonal plots (9.8 m wide) enclosed by a 2.4 m field fence with two openings (4.9 m) were established. Data were collected daily on consumption of corn provided (2.27 kg) and events recorded by infrared monitors (IR) for treatment and cont...

Food plots are a vital element for the survival of game bird species such as bobwhite quail (Colinus virginianus) on Fort Riley Military Installation in Kansas. However, white-tailed deer (Odocoileus virginianus) tend to eat the sorghum when it starts to ripen in September and continue feeding on it through November and December, often leaving no food for the quail during the winter. We conduct...
