The spatial and temporal distribution of forage quality is among the most central factors affecting herbivore habitat selection. Yet, for high latitude areas, forage quantity has been found to be more important than quality. Studies on large ungulate foraging patterns are faced with methodological challenges in both assessing animal movements at the scale of forage distribution, and in assessin...

Forage quality in grassland-savanna ecosystems support high biomass of both wild ungulates and domestic livestock. Forage quality is however variable in both space and time. In this study findings from ecological and laboratory studies, focused on assessing forage quality, are combined to evaluate the feasibility of a remote sensing approach for predicting the spatial and temporal variations in...

BACKGROUND Genetic engineering offers the opportunity to generate unique genetic variation that is either absent in the sexually compatible gene pool or has very low heritability. The generation of transgenic plants, coupled with breeding, has led to the production of widely used transgenic cultivars in several major cash crops, such as maize, soybean, cotton and canola. The process for regulat...

The change of the location of the beehives on the diverse honeyfull pastures is the usual apiarists activity in the Republic of Croatia. The main reasons are the climatic and vegetation diversity, and richness of the floral composition, with numerous bee forage plants. Our study aimed to detect consequences of honeybee broods (Queen-bee of different lineage) moving, from one habitat to another ...

Carbohydrates are the primiiary source of reserve energy stored in the vegetative organs of biennial and perennial forage plants. Reserves of available carbohydrates are essential to survival and to the production of plant tissues during periods when carbohydrate utilization exceeds photosynthetic activity. Total available carbohydrate3 levels and trends in storage organs are useful in indicati...

The fermentation of the neutral detergent-soluble (NDS) fraction of two legumes (clover, alfalfa) and two grasses (timothy, guinea grass) was measured using a curve subtraction technique with in vitro gas production data from the whole forage and the isolated neutral detergent-extracted fiber. The NDF disappearance and VFA production also were measured. There were no significant differences bet...

BACKGROUND AND AIMS Perennial ryegrass (Lolium perenne) is one of the key forage and amenity grasses throughout the world. In the UK it accounts for 70 % of all agricultural land use with an estimated farm gate value of 6 billion pounds per annum. However, in terms of the genetic resources available, L. perenne has lagged behind other major crops in Poaceae. The aim of this project was therefor...
