Spatial and temporal patterns of carabid activity-density in cereals do not explain levels of predation on weed seeds

open access: yes, 2008
Seed predation is an important component of seed mortality of weeds in agro-ecosystems, but the agronomic use and management of this natural weed suppression is hampered by a lack of insight in the underlying ecological processes.

Plant dispersal across the tropical Atlantic by wind and sea currents [PDF]

open access: yes, 2004
This review brings together evidence on the monophyly and ages of angiosperm lineages ranging across the tropical Atlantic with data on the direction, strength, and speed of sea currents and wind jets across that ocean. Mainly for pragmatic reasons (data

Context-dependent plant–bird interactions shape polychory across the antagonism–mutualism continuum

open access: yesCommunications Biology
Animals feeding on plants may benefit them through seed dispersal or harm them through seed predation, causing net interaction outcomes along an antagonism–mutualism continuum that remains poorly understood.

Photothermal‐Activated Antibacterial Amyloid‐Polyphenol‐Iron Hydrogels for Synergistic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
We report a thermally triggered supramolecular hydrogel (LTFe) formed by Fe3+ and tannic acid on lysozyme amyloid fibrils. Fe3+ enables rapid gelation and photothermal transduction with an efficiency of 88.56%. The LTFe hydrogel exhibits excellent biocompatibility, potent antibacterial activity against E. coli and S.

Seed ecology in dry sandy grasslands - an approach to patterns and mechanisms

open access: yes, 2013
Dry sandy grasslands occur throughout Central Europe and Southern Germany, and they host many rare and endangered plant species. To date, insufficient data on seed ecological aspects of this endangered vegetation type exist.

Functional Blood‐Brain Barrier Crossing by Biomimetic M13 Phage Vectors for Targeted Neuronal Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

3D‐Printed Piezoionic/Bioelectronic Hydrogel for Electro‐Metabolic Regulation of Osteogenic Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
A 3D‐printed piezoionic GPMx hydrogel enables stable electromechanical signal generation under mechanical loading, exhibiting long‐term durability and low fatigue. As a bioactive patch, it restores endogenous bioelectricity to stimulate osteogenesis via Ca2+ influx and mitochondrial activation, while simultaneously enabling label‐free alkaline ...

The impact of herbivores on the natural regeneration of temperate deciduous woodland [PDF]

open access: yes, 1999
Many studies have reported deficient or intermittent patterns of natural regeneration in temperate deciduous woodland. The present study aimed to assess the relative impact of herbivore-mediated plant mortality on the natural regeneration dynamics of ...
