After four years, some surprising findings, a pandemic, and taking care of over 20,000 noisy #caterpillars... ππ¦ I'm very pleased to have now submitted the final version of my PhD thesis at @SBSatEd. On #moths, #phenology, food chains, #climate change, and more π

In my **new paper**, out now in Folia Primatologica, I shed light on the nocturnal feeding habits of the Southern Lesser Bushbaby (Galago moholi), documenting observations made during fieldwork in S. Africa. https://t.co/aP03T62Lwe ...Scroll for more #bushbaby pics ππ π§΅ 1/8

Talk about an in-flight meal. For the first time, researchers have captured rats hunting bats by grabbing them from the sky. Learn more: https://t.co/UnliS1ZEsn

In summer, when insects are most abundant, they are a dominant part of the #diet of G. moholi. Understanding the kinds of insects eaten by bushbabies is key for their #conservation, and for unpicking their functional role in tropical/sub-tropical forest food-webs. π§΅ 8/8

Sound may act as an important proxy for prey size in nocturnal feeding behaviour. Bushbaby vocalisations are usually confined to social contexts, but I also made novel observations of vocalisations associated with solo foraging π£οΈπ π§΅ 7/8

Manipulative experiments using Male Driver Ants π - a popular prey item - suggested that while visual movement was a key driver of prey-finding behaviour in G. moholi, sound made prey items particularly attractive and increased the incidence of targeting for feeding. π§΅ 6/8

Prior evidence is mixed, w/ some reports emphasising a primary role for Lepidoptera in the diet, others suggesting Coleoptera and Orthoptera are most important (e.g. π). I observed G. moholi easily catch moths mid-flight, including strong fliers such as hawk-moths. π§΅ 5/8

Observing predation of different prey items, I found: β’ Moths were always consumed β’ Insects with distasteful or noxious secretions (Shield Bugs) were avoided β’ Beetles were examined before consumption, w/ only some eaten --> clear, species-level prey choice πππ¦ π§΅ 4/8

While recording moths at a UV light trap in S. Africa during Oct/Nov 2024, I was able to closely observe the Southern Lesser Bushbaby (G. moholi) foraging and predating insects drawn to the light. This fieldwork was generously supported by @SBSatEd Davis Expedition Fund. π§΅ 3/8

Much remains unknown about our #primate relatives. E.g./ #Insects are key in the diet of many #nocturnal species, but we still have little idea of: β’ which taxa are eaten, and why β’ indiv./pop./seasonal variation in preferences β’ #sensory stimuli used to find them π§΅ 2/8

These were the dinosaurs that faced the asteroid. Some of the last survivors. They lived in New Mexico, 66 million years ago. Among them was Alamosaurus, the size of a jetplane. We unveiled them, and their true age, today in a new paper in @ScienceMagazine!

Climate change can shift the seasonal timing of many species, and potentially disrupt feeding interactions between species that were formally synchronized in time. We identify a variety of mechanis...

It was a real delight to go down to Burlington House the other week, to tour the @LinneanSociety collections and receive this year's John C. Marsden medal, for the best biology PhD thesis in the UK. It was, and remains, a tremendous honour. Interested in my thesis? π

NEW: Researchers from @CamZoology @USDA_NIFA have found that bee-friendly flowers growing on disused urban land can accumulate toxins from contaminated soils. This gets passed on to bees as they forage, damaging their health. π But it can be managed β find out more:

It's an incredible honour to be awarded the John C. Marsden medal from the @LinneanSociety for my PhD research on phenology, moths... and some very hungry caterpillars π³π You can find out more about my work by clicking below and following the link π
Congrats @Jamie_C_Weir on winning @LinneanSociety John C. Marsden Medal for best doctoral thesis in biology, 'Buffering and trophic mismatch in spring-feeding forest caterpillarsβ Just how resilient is wildlife to a warming climate? β‘οΈ https://t.co/8bOXkvRtYB
