Floral visitors vary in their pollination efficiency and their preferences for floral traits. If low-efficiency pollinators decrease the amount of pollen available to higher efficiency visitors, then low-efficiency visitors may actually have negative fitness consequences for the plants that they visit. We used experimental arrays in two...


Insect-pollinated crops provide important nutrients for human health. Pollination, water and nutrients available to crops can influence yield, but it is not known if the nutritional value of the crop is also influenced. Almonds are an important source of critical nutrients for human health such as unsaturated fat and vitamin E. We manipulated...


Plant–pollinator interactions can be highly variable across years in natural communities. Although variation in the species composition and its basic structure has been investigated to understand the dynamic nature of pollination networks, little is known about the temporal dynamic of interaction strength between the same plant and pollinator...


If climate change affects pollinator-dependent crop production, this will have important implications for global foodsecurity because insect pollinators contribute to production for 75% of the leading global food crops. We investigatewhether climate warming could result in indirect impacts upon crop pollination services via an overlooked mecha-...


Tea tree (Melaleuca alternifolia) is known as an essential oil producer. This species is commercially important as a source of essential oil especially in Australia. To improve its oil quality, research on artificial pollination between plus trees were carried out. The information about self-incompatibility and inbreeding depression due to self...


Wildflower strips (WFS) are increasingly used to counteract the negative conse-quences of agricultural intensification. To date, it is poorly understood how WFS promote flower visitation and pollination services in nearby insect‐pollinated crops. We therefore ask whether WFS enhance pollination service in adjacent strawberrycrops, and how such...


There is evidence that pollinators are declining as a result oflocal and global environmental degradation[1–4]. Becausea sizable proportion of the human diet depends directly or in-directly on animal pollination[5], the issue of how decreasesin pollinator stocks could affect global crop production is ofparamount importance[6–8]. Using the...


Insect pollination in basal angiosperms is assumed to mostly involve ‘general-ized’ insects looking for food, but direct observations of ANITA grade (283species) pollinators are sparse. We present new data for numerous Schisandra-ceae, the largest ANITA family, from fieldwork, nocturnal filming, electronmicroscopy, barcoding and molecular...
