The ecological and evolutionary importance of nectar‐secreting galls [PDF]

Ecosphere, 2019
AbstractSome species of cynipid wasp engage in mutualisms with ants by producing nectar‐secreting galls, providing carbohydrates, and receiving protection from parasitoids. The galls are functionally similar to extrafloral nectaries, plant structures well known for their role in ant–plant mutualisms.

Floral resource‐mediated multilayer networks: structure and pollinators' roles

Oikos, Volume 2026, Issue 8, August 2026.
Resource availability shapes interactions among free‐living species, particularly in plant–pollinator mutualisms, where the composition of floral resource types influences pollinator foraging. Bees, known for utilizing a broad array of floral resources, play a crucial role in these dynamics. However, how the structure of interaction networks vary among

Flowering and Nectar Secretion in two Forms of the Moldavian Dragonhead (Dracocephalum moldavica L.) – A Plant with Extraordinary Apicultural Potential

Journal of Apicultural Science, 2018
Dracocephalum moldavica is a valuable reward plant for flower visitors. The aim of the study was to ecologically characterise its flowers and leaves and assess the seasonal and daily dynamics of flowering in two white- and blue-flowered forms of this ...

Patterns of nectar production and composition, and morphology of floral nectaries in Helicteres guazumifolia and Helicteres baruensis (Sterculiaceae): two sympatric species from the Costa Rican tropical dry forest

Revista de Biología Tropical, 2009
Helicteres guazumifolia Kunth and Helicteres baruensis Jacq. (Sterculiaceae) are two sympatric species of shrubs common along the North Western tropical dry forest of Costa Rica. i recorded their nectar production within a 24 hour cycle.

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, Volume 33, Issue 4, Page 1256-1284, August 2026.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

The structure of secretory tissue of the stigma and septal nectaries as well as nectar secretion of flowers of Hosta fortunei Baker L. H. Bailey (Funkiaceae)

Acta Agrobotanica, 2012
A study of Hosta fortunei Baker L. H. Bailey (Funkiaceae) flowers was conducted in the years 2007 - 2008. The flower life span and flowering duration as well as the nectar production rate were determined.

Diversity of Mites Associated With Stingless Bees (Hymenoptera: Meliponini) in Forest Fragments in Brazil: Empirical Validation of an Efficient and Low‐Cost Sampling Method

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Despite the importance of understanding mite–bee interactions, standardized and noninvasive methods for sampling mite communities in stingless bee hives remain limited. This study aimed to evaluate a novel, low‐cost sampling technique using a custom‐built suction device, the Portable Mite Aspirator (PMA), for collecting mites from hives of ...

Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

New Phytologist, Volume 251, Issue 4, Page 2266-2283, August 2026.
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 ...

Resilience of floral scent emission after florivory

Plant Biology, Volume 28, Issue 5, Page 1491-1506, August 2026.
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.

Floral biological investigations of apple cultivars in relation to fire blight

International Journal of Horticultural Science, 2004
Floral activity was studied in two apple cultivars: an Erwinia-tolerant (Treedorn') and a sensitive one (`Sampion'). Since more types of protogyny occur in apples, the period of stigma activity is different.
