Perspectives on deciphering mechanisms underlying plant heat stress response and thermotolerance [PDF]
, 2013 Global warming is a major threat for agriculture and food safety and in many cases the negative effects are already apparent. The current challenge of basic and applied plant science is to decipher the molecular mechanisms of heat stress response (HSR ...

Molecular and immunological characterization of profilin from mugwort pollen [PDF]
, 2002 In late summer in Europe, pollen of mugwort is one of the major sources of atopic allergens. No information about the complete molecular structure of any mugwort allergen has been published so far.

Observations and modelling of birch pollen emission and dispersion from an isolated source [PDF]
, 2014 The occurrence of allergic diseases in western countries increased during the last decades due to greater awareness towards a hygienic lifestyle. The hygiene hypothesis relates the reduced expo- sure to microbial pollution to an underdevelopment of the

A high resolution palynological study of the Holocene vegetational development of central Holderness, eastern Yorkshire, with particular emphasis on the detection of prehistoric human activity. [PDF]
, 2000 Compared to upland areas and Scotland, the Holocene vegetational history of lowland England is poorly known. This is particularly the case for the region of Holdemess, eastern Yorkshire, where only a low number of poor temporal resolution pollen diagrams

An Introduction to Pollen Analysis. [PDF]
American Midland Naturalist, 1944 POLLEN analysis is the term applied to the quantitative analysis of material containing pollen, by microscopic recognition of the species and genera of plants from which the pollen came. The pollen membranes have qualities of shape, size, surface, and structure which permit these identifications, and their preservation is often excellent.

Frontiers in Ecology and Evolution, 2022 Projected changes in climate are expected to shift the ranges of many tree species poleward and to higher elevations. Here, we examine past changes in forest composition in Pacific Canada using a paleoecological approach and investigate the role of past ...
