Resilience of pollinators in a changing world

We need to understand how climate change affects the nutritional health of wild bees and their pollination preferences, which are crucial for food security.
Our project measures and models how nutrition and temperature affect two key UK pollinators. We will be studying their growth, metabolism, and survival.
We will model how bumblebees and mason bees cope with climate heating and predict shifts in their flower preferences.
Our BBSRC-funded project is investigating the nutritional health of wild bees in a changing climate.
Animals’ dietary needs and preferences may change in a warmer world. Animals select from a range of foods to get the nutrient balance they need. But warmer temperatures may change this ideal balance.
We are investigating how this problem may affect bees, which are responsible for pollinating many of our crops. Crops provide bees with pollen that is very nutritionally different, and bees need to select a mix that is right for the conditions. The climate is heating up, so the crops bees choose to visit today may not be the same tomorrow.
We need to understand how changing climates will affect bee preferences and pollination patterns – unfortunately we still have limited understanding of bees’ dietary requirements, even in today’s climate.
We are looking at two UK bee species with different lifestyles.
Bumblebees pollinate soft fruit, beans and tomatoes. They have workers that feed larvae until adulthood and keep the nest warm in winter and cool in summer.
Red mason bees pollinate apples and other fruit. Mother bees work alone, provide larvae with a single pollen ball, and cannot control nest temperature.
In both species we are gathering detailed data on how nutrition and temperature affect bee health, establishing the best diet at a range of temperatures. Then, we will test whether adults can maintain optimal diets for larvae when the temperature changes.
Our work will fill a gap in our knowledge about how bees with different lifestyles cope with climate heating. With this knowledge, we can predict whether bees are likely to abandon particular crops in a hotter world, as they change their preferences, and design custom wildflower mixes to promote specific pollinators.
Once we understand bees’ dietary needs, and how these needs might change in warmer climates, we can design appropriate, future-proof mitigation/intervention measures.

Autumn is approaching, which means that fieldwork is coming to an end! With the weather getting colder and wetter, it was time to transfer the cocoons to the lab, where they will be protected from weather hazards such as heavy rain. We chose a particularly rainy and gloomy day to pack up all the equipment […]
We finally released the bees in early July! They emerged immediately from their cocoons but we quickly realised they looked rather unhappy in the cages…
We have been very busy at our field site at Stockbridge Technology Centre near Selby, a centre for agricultural and horticultural innovation and testing. Having installed the fruit cages last month, this month we put up 9 mesh cages, each of which will house a bee nesting block that will be kept at one of 3 […]
Gearing Up for Bee Season: Excitement in the Field! As spring progresses, so does our fieldwork season, and we were all excited to be outdoors, ready to set up for our flight cage experiment. This year, the focus is on understanding how nesting temperatures affect the foraging behaviour and offspring outcomes of Osmia bicornis, a […]
