Climate variability and human impact in South America during the last 2000 years: synthesis and perspectives from pollen records [PDF]

, 2016
An improved understanding of present-day climate variability and change relies on high-quality data sets from the past 2 millennia. Global efforts to model regional climate modes are in the process of being validated against, and integrated with, records

Uneven Culturable Yeast Communities Harbored by Two Sympatric Stingless Bee Species: Scaptotrigona depilis and Tetragona clavipes

Yeast, EarlyView.
To explore the yeast diversity associated with Brazilian stingless bees, we collected samples from bees and their provisions. Sympatric bee species harbor distinct yeast communities, providing insights into bees' foraging choices. Moreover, these communities are dominated by specific taxa with similar metabolic profiles.

MicroPoem: experimental investigation of birch pollen emissions [PDF]

, 2010
Diseases due to aeroallergens constantly increased over the last decades and affect more and more people. Adequate protective and pre-emptive measures require both reliable assessment of production and release of various pollen species, and the ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Cytogeography of Gagea bohemica (Liliaceae) outside the Mediterranean: two ploidy levels, spatial differentiation of cytotypes, and occurrence of mixed-ploidy populations

, 2023
Gagea bohemica s.l. is a morphologically and karyologically highly variable group with many morphologically similar “narrow” taxa currently considered as a single variable species.

Kinetics of Antibody Responses and Effector Cell Sensitivity After High Dose Birch Extract Nasal Challenge

Allergy, EarlyView.
High‐dose birch‐extract nasal challenge induced synchronous peaks at 4 weeks in serum specific IgE (sIgE) and basophil sensitivity. Mast cell sensitivity via tSPT and sIgG1 and sIgG4 responses peaked later, at 6–8 weeks. Preseasonal allergen exposure attenuated seasonal sIgE increase and prevented further rise in tSPT sensitivity.

Effect of sporophytic heterozygosity on the male gametophyte of the tetraploid potato (Solanum tuberosum)

, 2018
Quantitative variation for pollen stainability was examined in both tetraploid × diploid and tetraploid × tetraploid families of potato (Solanum tuberosum L.). The diploid parents, which were highly heterozygous, produced first division restitution (FDR)

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.

Mapping Allergen B‐ and T‐Cell Epitopes: Technological Advances and Their Role in Precision Allergy Therapy

Allergy, EarlyView.
ABSTRACT Allergic diseases arise from aberrant immune recognition of otherwise harmless environmental proteins and are driven by epitope‐specific interactions between allergens and the adaptive immune system. Although component‐resolved diagnostics have improved molecular characterisation of sensitization, they remain limited to whole‐allergen ...
