Identification and analysis of bee pollen constituents

open access: yes, 2021
Medonosne pčele (Apis melifera L.) skupljaju pelud s antera biljaka, miješaju ga s izlučevinama slinovnica u kojima se nalaze različiti enzimi (amilaza, katalaza) te oko 10% nektara i kao takvog ga na goljenicama stražnjih nogu (pčelinja pelud) unose u ...

Projected Climate‐Suitable Area for Apis mellifera (Apidae) and Its Spatial Overlap With a Mining Tailings Footprint in South‐East Brazil

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

open access: yesNew Phytologist, EarlyView.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

open access: yesPhysiological Entomology, EarlyView.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

open access: yesPhysiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.
