In this podcast, Robbie Wilson discusses a recent paper showing that long term exposure to a neonicotinoid pesticide ca damage bees’ ability to forage for pollen – and may be changing their choices of which flowers to visit – with co-author Nigel Raine.

Stag beetles are renowned for their spectacular male-male battles. In these scuffles, males fight each other with their long jaws over mates or desirable stumps of rotten wood. As a result of this, their jaw is strongly shaped by sexual selection and in some species, can become as long as their own body. How does this effect their ability to run? To investigate this, the authors made high speed video recordings of male and female stag beetles running on a miniature running track.

Cynthia Chang talks with Alan Knapp about why naturally co-occurring genotypes coexist, how genetic diversity within dominant plant species is maintained and how this can affect important ecosystem processes.

Hovering hummingbirds are rare among vertebrates in their ability to rapidly make use of ingested sugars to fuel energetically expensive hovering flight, powering up to 100% of their metabolic needs with the sugars they drink, while humans athletes max out at around 30%. Until now, we haven't understood to what extent hummingbirds can use the 50% of the sugar in their nectar meals that is glucose versus the 50% that is fructose. Our study shows that hummingbirds begin using newly ingested sugars to fuel hovering flight within minutes and can fuel as much as 100% of their intense hovering metabolism with either glucose or fructose.

Animals move within natural habitats in complicated ways, in response to many aspects of the environment. Advances in the technology available for recording and analysing animal movements enabled us to ask and answer questions that were inaccessible with previous methods. Our transmitters provided over 60,000 records of lizard location from 49 individuals monitored for a mean of 65 days each. Lizards primarily moved between widely scattered patches of core-habitat under fine, hot, clear weather conditions. Thus air pressure tended to predict lizard dispersal more accurately than did more commonly-analysed variables such as temperature and precipitation.
