Abstract:
... This study aimed to understand the effects of Medicago spp proportion on symbiotic and non-symbiotic nitrogen (N) utilization of plants, and subsequent forage production and soil N status in an artificial Leymus chinensis grassland. By a two-year field experiment conducted in semi-arid northern China, it was found that the corresponding biomass proportions of legume in swards were 0, 39, 63, 83 an ...

Abstract:
... Many animals are surface-bounded, traveling mostly in two-dimensional (2D) environments. However, those that inhabit structured habitats might also require wayfinding in three-dimensional (3D) environments. Here we forced rodents to ascend or descend when traveling. We tested three species: laboratory rats (a common experimental subject); fat sand rats, which forage while climbing shrubs (represen ...

In an enclosed glasshouse with sucrose provisioned artificial flowers, we observed nectar-foraging bumble bees and honey bees under several resource conditions to determine potential for displacement. Different responses were displayed for varying resource treatments. Overall, bumble bees did not show reduced foraging in the presence of honey bees. When resources were reduced, bumble bees did not ...

Abstract:
... The main constraints in the ruminant production systems in the tropics are low availability and quality of forage during the dry season. An alternative that could mitigate the lack of food during periods of scarcity is the use of trees/shrubs in fodder banks. However, the growth and production response of these plants may be influenced by several factors. The aim of the study was to evaluate the t ...

Heriades truncorum (Megachilidae) is a specialist bee that forages on Asteraceae and collects pollen by tapping its abdomen on pollen-presenting florets which places the grains directly in the ventral scopa. We tracked pollen transfer by female H. truncorum between conspecific inflorescences of Inula ensifolia and Pulicaria dysenterica by labelling pollen with quantum dots. On average, bees transf ...
