Summary
Most bee species are solitary, but honeybees, which live in colonies, exhibit remarkable collaboration to defend against various threats, including bacterial diseases and varroa mites. Microbiologist Kenya Fernandez leads research on the hive's immune system, revealing how bees utilize honey, bee bread, and propolis to protect their colonies. These substances are not just for human benefit; they serve critical roles in the bees' survival and health.
Fernandez's study involves sampling bees and hive materials from Tocal Agricultural College, where researchers analyze the antimicrobial properties of these products. The findings indicate that these substances work synergistically to create a spatially organized defense system within the hive. The most vulnerable larvae are located in the hive's center, surrounded by materials specifically targeting pathogens that threaten them. As one moves outward, the antimicrobial properties of the food stores, such as honey and pollen, are less potent, while the outermost layer, which interfaces with the environment, is fortified with propolis to block outside threats.
The research highlights the importance of biodiversity in the local environment for bee health. Bees that have access to a diverse range of plants can build stronger immune defenses, while those in monoculture settings may struggle. The study also points out that while honeybees can effectively defend against severe bacterial threats like American fowl brood, they are less impacted by fungal pathogens, which tend to be more of a nuisance than a fatal threat. Overall, the research underscores the critical role of environmental diversity in maintaining healthy bee populations and the intricate ways bees protect their hives from pathogens.
Show Notes
Bees survive by collaboration. To fight infection, bees arrange their honey and other stores in ways that repel disease. Microbiologist and bee researcher Kenya Fernandes led a study into the ways bees arrange their hives for maximum protection from microbial infection.

No more “Red In Tooth and Claw”? Well, that’s not the only story in evolution – from the beginning. Rowan Hooper in his latest book, Togetherness, shows how lichens, corals and even ourselves, flourish by means of other life forms. We have mitochondria, plants have chloroplasts, both formerly free-living creatures. We would not have evolved to our current form and could not survive without these once-invaders.
Lions are under considerable stress across Africa. Their habitat is fragmented and impacted by human activity such as agriculture. Being unable to roam freely, has led to inbreeding. Climate change is expected to impact their habitat and bring additional stress.
Why did reptiles prevail for so long and why did mammals take so long to become dominant predators? Adam Lindholm is looking at body size, availability of prey and environmental conditions to reconsider our understanding of the history of reptiles and mammals.
Theme parks and museums draw big crowds for dinosaurs. Kids love them. But palaeontologist James Ronan says some displays are based on ideas from the 1970s and present sound effects from movies. He says it is important to present current ideas about palaeontology accurately. So James Ronan is undertaking a worldwide audit of dinosaurs. Science communicator and podcast host Conor O’Keefe is also disturbed by inaccurate dinosaur displays at theme parks and supports the dinosaur edit saying it is long overdue.
Over the past few years, our environment seems to have experienced multiple extreme events in quick succession. With a summer fuelled by what may be the strongest and wettest El Niño ever, can our wildlife withstand more extremes? Jonathan Webb speaks with Professor Euan Ritchie about what we're currently seeing with flying foxes, what could happen to other species over the summer, and what we can do to help our native creatures.
