Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

Application of pollen mixing device in front of the hive entrance

open access: yesInternational Journal of Horticultural Science, 2000
The model of a pollen mixing device was tested in sunflower culture in order to detect the effectiveness in helping the out-going honey bees to carry more and different varieties of pollen grains on the body and body hairs.

Creation of a Pseudotsuga menziesii nucellus cell suspension culture system to produce proteins involved in reproduction

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Cell suspension cultures of Douglas‐fir (Pseudotsuga menziesii) nucellus were created to overcome phenological limitations to the in situ study of bioactive proteins within and secreted by nucellar cells. Methods Proteins isolated from the cell suspension culture medium were analyzed using mass spectrometry, as were Douglas‐fir post ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

open access: yesThe Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Comparative palynomorphological characteristic of plants with different types of ecological strategies

open access: yesІнтродукція Рослин, 2011
Pollen grains of 5 species with different types of ecological strategies were studied using light and scanning electron microscopy. Pollen grains of Rumex tianschanicus and Brassica campestris were analyzed by these methods at first time.
