New Phytologist, EarlyView.Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Acta Agrobotanica, 2021 The attractiveness of plants to pollinators depends strongly on flower rewards, especially nectar and pollen. Nectar mass, sugar concentration, and sugar mass are known to influence the spectrum and abundance of insect visitors. Respective data on nectar

Resilience of floral scent emission after florivory
Plant Biology, EarlyView.Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Ecology and Evolution, Volume 16, Issue 7, July 2026.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.

The position and structure of the nectary in spring heath (Erica carnea L.) flowers
Acta Agrobotanica, 2012 Ecological traits of Erica carnea L. flowers and the morphology of floral nectaries were investigated using stereoscopic, light and scanning electron microscopy. The nectary in the flowers of Erica carnea is located in the basal part of the ovary.

Beyond Average Hive Performance: Tail Risk Measurement in Italian Apiculture With Honey‐at‐Risk
Environmetrics, Volume 37, Issue 5, July 2026.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 ...

Nectar secretion dynamics of Hungarian local pear cultivars [PDF]
Plant Systematics and Evolution, 2003 The dynamics of daily nectar secretion was studied in 28 local pear cultivars in a Hungarian cultivar collection and three main types were distinguished. 1. Cultivars secreting nectar continuously are the most favourable for pollinators, rewarding them both with nectar and pollen. 2.
