Herbivory can aff ect plant community composition and diversity by removing biomass and reducing light competition. Herbivory may particularly benefi t low growing species such as bryophytes, which are frequently limited by light competition. Gastropods are important herbivores of seed plants and cryptogams, furthermore, they can disperse propagules such as seeds and spores via endozoochory. Ho...
From 2003 to 2008, 176,643 Gratiana boliviana Spaeth (Coleoptera: Chrysomelidae) were released in Florida as part of a biological control program targeting tropical soda apple (TSA) Solanum viarum Dunal (Solanaceae). The spatial distribution of releases was clustered with more beetles released in south/central Florida than further north. A survey conducted in the fall of 2008 found G. bolviana ...

Soybean field experiments were performed to investigate the weed-suppressing effects of different tillage systems and cover crop mulches at two locations in southwest Germany during 2014 and 2015. The influence of three different tillage systems on weed control efficacy, soybean plant density, and crop yield was determined. In the no-till system (NT), two different cover crops, (rye and barley)...
We propose an optimization model that enables the selection of biofuel conversion technologies, processing capacities and locations, and the logistics of transportation from the locations of forestry resources to the conversion sites and then to the final markets. A mixed integer linear program (MILP) model is built to solve for (1) the optimal number, locations, and sizes of various types of p...
Vegetation cover is the first barrier for the raindrops resulting to the interception and infiltration loss. Interception as one of the main components of ecohydrology equation plays a major role in the water balance of rangelands. However, few studies have been done on the interception of rangeland plants in Iran. This study was carried out to find the interception rate in Astragalus parrowian...
The goal of this tutorial is to provide an overview of recent systematic constructions to deal with plants having redundant actuators. For these plants, the presence of multiple actuators with overlapping features presents an interesting allocation problem, typically encompassing a suitable performance goal that pertains the selected input pattern. Within the tutorial we plan to cover a number ...
