Bumble bees in landscapes with abundant floral resources have lower pathogen loads

Scientific Reports, 2020
The pollination services provided by bees are essential for supporting natural and agricultural ecosystems. However, bee population declines have been documented across the world.

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.

Unshared on the top: strong segregation of pathogen communities between western honey bees and wild bees in a retreating glacier foreland

Oikos, EarlyView.
Shared flowers can facilitate pathogen transmission between managed honey bees and wild bees, yet this process remains poorly understood in ecosystems undergoing rapid environmental change. Using a glacier foreland in Switzerland, we present the first study on how glacier retreat stages and bee life‐history traits influence pathogen occurrence across ...

Reproduction of Varroa destructor in sealed worker bee brood cells of Apis mellifera carnica and Apis mellifera syriaca in Jordan [PDF]

, 2008
The reproduction of the honey bee mite, Varroa destructor in sealed worker bee brood cells represents an important factor for the population development of this parasite in honey bee colonies.

Resilience‐as‐doing: A relational model for living practice

People and Nature, EarlyView.
Abstract Dominant frameworks treat resilience as a capacity to withstand disturbance and recover, something systems, communities or individuals either have or lack. This paper proposes a different understanding, grounded in relational onto‐epistemology and first‐person, practice‐based, autoethnographic inquiry situated within a household garden.

Multiple barriers maintain species boundaries in sympatric brood‐site deceptive Gastrodia orchids

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Gastrodia orchids are inconspicuous forest plants that lack chlorophyll and obtain carbon from fungi. Their dull‐colored, ground‐level flowers are often hidden among leaf litter, yet they rely on small flies for pollination.

When alien plants become health hazards: An applied study on toxic and allergenic risks in Italy

PLANTS, PEOPLE, PLANET, EarlyView.
Alien plants are often studied for their ecological harm, but their risks to human and animal health remain poorly documented. This study provides the first comprehensive catalogue of poisonous and allergenic alien plants in Italy, identifying which species are dangerous, where they grow and who is most at risk—from children in city parks to pets and ...

Bacterial communities of wild bee species and the honey bee : alpine insights

Wild bees are decreasing in species and populations due to human impact. The western honey bee (Apis mellifera) experiences an inverse trend, enhancing competition with wild bees and also probability of microbiome exchange.

Melittin Reprograms Tumor‐Associated Macrophages Through CD18‐Mediated Immunomodulation

Phytotherapy Research, EarlyView.
Melittin selectively targets CD18 to deplete M2‐TAMs and remodel the TME to suppress tumor growth. ABSTRACT Tumor‐associated macrophages (TAMs), particularly the M2‐like subtype, contribute to an immunosuppressive tumor microenvironment and promote tumor progression.
