Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure
Oikos, EarlyView.Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

ANALYSIS OF ATMOSPHERIC POLLEN GRAINS IN DURSUNBEY (BALIKESİR), TURKEY
Trakya University Journal of Natural Sciences, 2018 In this study, airborne pollen grains in the atmosphere of Dursunbey (Balıkesir, Turkey) were collected using a gravimetric method. The pollen grains were investigated by light microscopy and a total of 6265 pollen grains per cm2 were counted.

Oikos, EarlyView.Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

The limitations of the methods of identifying the floral source of honeys [PDF]
, 1998 The pollen grains in honey reveal the types of plants that were around when the bees produced the honey, thus it is valid to use melissopalynology to determine the geographical origin of honeys, but there are several reasons why it is less valid for ...

People and Nature, EarlyView.Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

PLANTS, PEOPLE, PLANET, EarlyView.Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca
PLANTS, PEOPLE, PLANET, EarlyView.The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

MICROMORPHOLOGY OF POLLEN GRAINS OF FRUIT TREES OF THE GENUS Prunus
Acta Scientiarum Polonorum: Hortorum Cultus, 2015 The micromorphological characteristics of the pollen grain sculpture is one of the most important diagnostic traits in plants. Pollen grains in various species of the subfamily Prunoideae are characterized by variations in size, shape and exine ...
