Systemic fungal endophytes (Clavicipitaceae) of grasses reproduce sexually when the fungus forms stromata and contagious ascospores, or asexually by vertical transmission of hyphae into seeds and seedlings. Vertical transmission is predicted to favor reduced virulence compared with horizontal transmission in systems with both types of transmission. Here, variation in vertical and horizontal tra...
Plants grown in lead contaminated soils can accumulate lead from the adherence of dust and translocation into the plant tissue. In order to evaluate the potential health hazard due to the consumption of plants grown in residential gardens contaminated by lead, a survey of the lead concentrations in a typical array of edible vegetables, fruits and herbs was conducted. Samples of garden plants ha...
This paper describes the architecture and implementation of a distributed autonomous gardening system with applications in urban/indoor precision agriculture. The garden is a mesh network of robots and plants. The gardening robots are mobile manipulators with an eye-in-hand camera. They are capable of locating plants in the garden, watering them, and locating and grasping fruit. The plants are ...
Intraspecific plant diversity can modify the properties of associated arthropod communities and plant fitness. However, it is not well understood which plant traits determine these ecological effects. We explored the effect of intraspecific chemical diversity among neighbouring plants on the associated invertebrate community and plant traits. In a common garden experiment, intraspecific diversi...
Abstract Founded in 1760, the Cambridge Botanic Garden was designed to serve theological interests of university by developing a collection living plants from across globe. Exploring construction and layout garden, its global network, methods managing information, accessibility during professorship Thomas Martyn between 1762 1825, this article casts new light on motivations for founding botanic...
In 1665 Johan Stickers had established himself as apothecary in "De Witte Pluym" at the Grote Markt in Breda. In 1669 he bought a garden at the Gasthuiseinde, where he must have grown herbs. This purchase was followed by many others. In and around Breda, Stickers and his wife Anneken Geerit Claess de Gruyter acquired a number of houses, grounds, landed estates, meadows, orchards, and farms. In ...
Chilling (0-18°C) and freezing (<0°C) are two distinct types of cold stresses. Epigenetic regulation can play an important role in plant adaptation to abiotic stresses. However, it is not yet clear whether and how epigenetic modification (i.e., DNA methylation) mediates the adaptation to cold stresses in nature (e.g., in alpine regions). Especially, whether the adaptation to chilling and freezi...
Aquaponics, the portmanteau of “aquaculture” and “hydroponic”, is a sustainable food production system that combines the raising of aquatic animals such as fish in tanks (i.e. aquaculture) with the cultivation of plants in water (i.e. hydroponics) in a symbiotic environment [1]. In this paper we describe a new visualization approach that allows aquaponic gardeners to quickly monitor the status ...
1. Genetic variation within and among foundation plant species is known to affect arthropod, plant and soil microbial communities. We hypothesized that the same would be expected for pathogen communities, which have typically been studied only as individual pathogen species. 2. In a common garden in Utah, USA, we first tested how genetic differences within and among Populus angustifolia, P. fre...
