Macronutrient composition in pollen affects development and survival in wild bees
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

Turgor loss point explains climate‐driven growth reductions in trees in Central Europe
Leaf turgor loss point of native tree species shows a high predictive power over the observed growth anomalies in Central Europe during the extensive drought period between 2018 and 2020. Abstract As climate change thrives, and the frequency of intense droughts is affecting many forested regions, a mechanistic understanding of the factors conferring ...

Sap flow and reversible stem shrinkage upon water depletion are strongly correlated under extreme drought conditions, but they respond differently to drought and cannot be used interchangeably when assessing tree response to drought. Abstract Temperate mixed forests are currently experiencing severe drought conditions and face increased risk of ...

Severe thunderstorm (likely supercell) tracked from Georgian Bay into the Metro area caused significant damage to a number of areas. Golf ball sized hail fell and much lightning occurred causing at least one death and damaging structures. Two tornadoes confirmed from damage paths found after storm. One police officer noted the storm as the worst he had

Mature beech trees redistributed soil water, equal to ca. 10% of stand transpiration, from deeper moist soils to dry surface soils, where it was taken up by seedlings of different tree species. Abstract Hydraulic redistribution is considered a crucial dryland mechanism that may be important in temperate environments facing increased soil drying–wetting

Three species of the mycoheterotrophic orchid genus Yoania found in Taiwan and China are associated with a single taxonomic unit of white‐rot fungus from the genus Physisporinus and exhibit a stable isotope pattern distinct from other fully mycoheterotrophic (FMH) orchids associated with wood‐decaying fungi.

Natural Arabidopsis thaliana accessions showed remarkable plasticity in both life‐cycle phenology and whole‐genome gene expression patterns in in natura field experiments. Nevertheless, local adaptation in fitness‐related life‐history traits can also be detected at the whole‐genome gene expression level.
