Warming‐Mediated Decreases in Nectar Quality Translate Into Lower Energy Reserves of the Monarch Butterfly (Danaus plexippus)

Global Change Biology Communications, EarlyView.
Warming caused a significant decrease in monarch fat mass, likely due to an observed reduction in sucrose concentration caused by warming of the nectar. Since sucrose fuels fall migration and overwintering, our results suggest climate warming may reduce migration success and overwinter survival.

Automation of pollen analysis using a computer microscope : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University [PDF]

, 2004
The classification and counting of pollen is an important tool in the understanding of processes in agriculture, forestry, medicine and ecology. Current pollen analysis methods are manual, require expert operators, and are time consuming.

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

Grassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Spatio-temporal variation in pollen collected by honey bees (Apis mellifera) in rural-urban mosaic landscapes in Northern Europe.

PLoS ONE
Pollen is a source of protein, lipids, vitamins and minerals for bees and other flower-visiting insects. The composition of macro- and micronutrients of pollen vary among different plant species.

Functional Stability Despite Taxonomic Changes in Mixed‐Species Foraging Flock Participants Along an Elevational Gradient in Knuckles Montane Reserve, Sri Lanka 斯里兰卡纳克斯山地保护区 (Knuckles Montane Reserve) 海拔梯度上混合物种觅食群参与者的功能稳定性与分类变化

Integrative Conservation, EarlyView.
This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Examining the Effects of Prunus Necrotic Ringspot Virus (PNRSV) and Prune Dwarf Virus (PDV) on Peach (Prunus persica) Pollen Health

PhytoFrontiers
Pollen health is a key determinant of successful plant reproduction and crop yield. Prunus necrotic ringspot virus (PNRSV) and prune dwarf virus (PDV) are pollen-borne viruses of stone fruits, including peaches, primarily transmitted through vegetative ...

Potential for gene-flow from cultivated Irish grasses and cereals [PDF]

, 2009
End of project reportThe importance of gene movement from cultivated plants has been highlighted in regard to minimising the movement of seed and/or pollen between GM and non-GM crops (i.e. gene flow). Although ryegrass covers in excess of 90% of Ireland’
