Pollen Analysis of a Peat Deposit in Livingston County, Illinois [PDF]

open access: yes, 1951
This study essays to compare, and in some degree to supplement, pollen analyses thus far published for Illinois. Even though results of studies of fossil pollens seem very similar, each pollen profile is individual and varies in many details from all ...

Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]

open access: yes, 2011
Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here

Restoring the lost Ericaceae of Botany Bay's scrublands through a paleoecological approach in southeastern Sydney, Australia

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction With anthropogenic environmental change accelerating, incorporating long‐term perspectives into ecological restoration is essential. Paleoecological evidence increasingly indicates that many perceived “natural” landscapes under current conservation regimes are, in fact, cultural or modern systems.

Glyptostrobus europaeus (Brongn.) Heer in Arkansas [PDF]

open access: yes, 1970
Glyptostrobus europaeus (Brongn.) Heer, a fossil gymnosperm is found at a few locations in central North America, in deposits of the Eocene. This work cites previously reported localities and reports a new site at Hooker, Arkansas.

Terrestrial climate variability and seasonality changes in the Mediterranean region between 15 000 and 4000 years BP deduced from marine pollen records [PDF]

open access: yes, 2009
Pollen-based climate reconstructions were performed on two high-resolution pollen marines cores from the Alboran and Aegean Seas in order to unravel the climatic variability in the coastal settings of the Mediterranean region between 15 000 and 4000 ...

Poaceae Pollen From Southern Brazil: Distinguishing Grasslands (Campos) From Forests by Analyzing a Diverse Range of Poaceae Species

open access: yesFrontiers in Plant Science, 2016
This aim of this study was to distinguish grasslands from forests in southern Brazil by analyzing Poaceae pollen grains. Through light microscopy analysis, we measured the size of the pollen grain, pore, and annulus from 68 species of Rio Grande do Sul ...

An effective palynological preparation procedure using hydrogen peroxide [PDF]

open access: yes, 2007
Most pre-Quaternary palynology samples are currently prepared by demineralization of the sediment/sedimentary rock matrix using hydrochloric and hydrofluoric acids (HCl and HF respectively).

Bio‐Based Wax Interfaces for Droplet Energy Harvesting at Fluoropolymer‐Like Output Levels

open access: yesAdvanced Science, Volume 13, Issue 15, 13 March 2026.
Replacing unsustainable fluorinated polymers in droplet‐based energy harvesters is usually limited by low power outputs, but carefully selected bio‐based polymers are capable of creating fluoropolymer‐like voltage outputs. Abstract Droplet impact and rebound on solid surfaces has emerged as a promising method for energy harvesting, typically ...
