Thermoregulating lotus flowers
Article Abstract:
Research has shown that flowers such as the sacred lotus are able to regulate internal temperature similar to homeothermic animals. To control internal temperature, flowers increase the rate of heat production in proportion to the decrease in ambient temperature. These homeothermic episodes become more pronounced during the flowering periods. Researchers have hypothesized that flowers control their internal temperatures during flowering to enhance the evaporation of floral scents to attract pollinators.

Diving insects boost their buoyancy bubbles
Article Abstract:
Backswimmers (Notonectidae), the common diving insects, achieve prolonged periods of neutral buoyancy by using oxygen stored in their haemoglobin to stabilize the volume of the bubble as they breathe from it. This enables them to maintain their position in the water column without continually swimming.

Heat reward for insect pollinators
Article Abstract:
The thermogenic flower of Philodendron solimoesense which is found in the neotropical forest of French Guiana is described. The floral temperatures in Philodendron solimoesense in French Guiana, and the respiration rates of Cyclocephala colasi beetles at floral and ambient temperatures are measured.
