Micro- and Macroelements Content in Soil, Plants Nectaro-Pollenifer Leaves, Pollen and Bees Body

Scientific Papers Animal Science and Biotechnologies, 2023
Taking into account the fact that quality and biological value of bee products depend on the chemical composition and taking account of the environmental situation, studying the content and dynamics of micro-, macro elements composition of soil, plant ...

Area‐restricted search under realistic constraints

Oikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Specialized metabolites present in Camellia reticulata nectar inhibit the growth of nectar‐inhabiting microorganisms

Frontiers in Plant Science
Plant specialized metabolites are species-specific compounds that help plants adapt and survive in constantly changing ecological environments. Nectar contains various specialized metabolites, essential for maintaining nectar homeostasis.

A plant–pollinator invasional meltdown: the Japanese pagoda tree Styphnolobium japonicum facilitates the invasion of the giant resin bee Megachile sculpturalis

Oikos, EarlyView.
An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

Variability of nectar production and composition in Linaria vulgaris (Scrophulariaceae)

, 2002
We studied nectar characteristics during the long flowering period (late June to end of November) in two populations of Linaria vulgaris (L.) Mill. spontaneously growing in the Botanical Gardens of Siena University (Tuscany, central Italy).

Life‐history traits and phylogeny structure taxon‐specific species–substrate relationships in deadwood

Oikos, EarlyView.
To understand the structuring of species assemblages, integrating life‐history traits and evolutionary heritage in analyses is vital. This allows the assessment of a mechanistic link between species and their environment. Deadwood systems are vital for nutrient cycling and biodiversity support, governed by complex intra‐ and inter‐specific fungal and ...

Nectar and pollen in Acer trees can contribute to improvement of food resources for pollinators

Scientific Reports
In the present study, we quantified floral resources (nectar and pollen production) and their quality (nectar sugar composition, pollen protein content, pollen amino acid composition) in five Acer species (f.

Demonstrating limitations of area‐restricted search as a foraging mechanism

Oikos, EarlyView.
Foragers often rely on simple behavioral rules that translate local environmental cues into movement decisions. One of the most widespread rules is area‐restricted search (ARS), in which movement becomes less directional following resource encounters. ARS is generally considered effective for exploiting clustered resources, yet recent conceptual work ...
