Przestrzenne i czasowe zróżnicowanie Apoidea w lasach Wielkopolskiego Parku Narodowego [PDF]

open access: yes, 1994
Results of the investigations of spatial and temporal differentiations of Apoidea in the forests of Wielkopolski National Park were presented. It was shown that the both forest floor differ with the degree of species differentiation and domination’s ...

Effects of Flight on Gene Expression and Aging in the Honey Bee Brain and Flight Muscle [PDF]

open access: yes, 2012
Honey bees move through a series of in-hive tasks (e.g., “nursing”) to outside tasks (e.g., “foraging”) that are coincident with physiological changes and higher levels of metabolic activity.

In Vitro and In Vivo Effect of Amitraz on Honey Bee Drone Sperm Quality

open access: yesActa Zoologica, EarlyView.
ABSTRACT Honey bee hive infestation by the ectoparasitic mite, Varroa destructor, has been a major cause of declining populations. Treating such infestations is important for sustainability. Knowledge about the sub‐lethal effects of commonly used acaricides on drone reproductive health, particularly sperm quality, is limited. The effect of in vitro and

Diseases of Honeybee (Apis mellifera)

open access: yes
Honeybees, important pollinators crucial for ecosystem health, are susceptible to a range of bacterial, fungal, and viral diseases that pose significant threats to their colonies. Bacterial diseases include American Foulbrood (AFB) caused by Paenibacillus larvae and European Foulbrood (EFB) caused by Melissococcus plutonius. AFB results in the death of

Closing the air gap: the use of drones for studying wildlife ecophysiology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Techniques for non‐invasive sampling of ecophysiological data in wild animals have been developed in response to challenges associated with studying captive animals or using invasive methods. Of these, drones, also known as Unoccupied Aerial Vehicles (UAVs), and their associated sensors, have emerged as a promising tool in the ecophysiology ...

The complex world of honey bee vibrational signaling: A response to Ramsey et al. (2017) [PDF]

open access: yesarXiv
Ramsey et al. report on the characteristics and temporal distribution of an interesting vibrational signal that they term the whooping signal, primarily based upon a long-term study of vibrations recorded by accelerometers placed inside two honey bee (Apis mellifera) colonies, one in France and one in the United Kingdom. The goal of the study, the long-

Lords of the flies: dipteran migrants are diverse, abundant and ecologically important

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insect migrants are hugely abundant, with recent studies identifying the megadiverse order Diptera as the major component of many migratory assemblages. Despite this, their migratory behaviour has been widely overlooked in favour of more ‘charismatic’ migrant insects such as butterflies, dragonflies, and moths.
