We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

Beyond Average Hive Performance: Tail Risk Measurement in Italian Apiculture With Honey‐at‐Risk
ABSTRACT This paper provides a framework for measuring honey‐production risk that complements standard mean‐based analyses by explicitly targeting downside tail risk. Using hive‐weight data from a large sample of Italian hives over the period 2021–2024, downside tail risk is quantified through the Honey‐at‐Risk (HaR) metric, defined as the quantile of ...

ABSTRACT This study investigates the outcomes of the implementation of a first grade unit incorporating multiple modes of representation and genre‐based pedagogy to support writing instruction in the genre of sequential explanations. At the end of a 6‐day unit investigating the structure and functions of carnivorous plants, 47 first graders completed a

ABSTRACT Plants mediate the supply of energy and matter for all animals, including human beings yet we are faced with “plant blindness” whereby we pay limited attention to and accord little value to plants. Plant blindness is evident in school curricula whereby students have limited opportunities to learn about plants.

The common perennial weed Achyranthes bidentata (Amaranthaceae) produces many flowers to attract diverse insect pollinators. The authors here found that lycaenid butterflies made long‐distance visits between individual plants, whereas honeybees were inclined to visit multiple flowers within an individual plant. These findings highlight potential agents
