How Temperature affects Growth
 
03:38
Can an oxygen perspective explain the effects of temperature on growth? Breathing under water is challenging, making it potentially difficult for ectotherms to meet their higher oxygen demand in warmer waters. This animation explains how an oxygen perspective helps to explain why temperature may differently affect small and large animals, providing an explanation for the temperature-size rule. In a previous animation we showed that the balance between oxygen supply and demand changes as animals grow (see http://www.youtube.com/watch?v=QCskh6NVa7U ).

Ecology: Oxygen & Cold Blooded Animals
 
04:40
How do changes in temperature affect the amount of oxygen that is available to cold-blooded, aquatic animals? Oxygen partial pressure, solubility and diffusivity all influence the amount of oxygen that is available to these animals. This animation explains how these elements interact to provide a better understanding of oxygen supply and demand, showing that oxygen governs patterns in body size and species diversity.

Ecology: Oxygen & Growth of Aquatic cold blooded animals
 
04:43
Breathing under water is challenging. How does the oxygen uptake of cold-blooded, aquatic animals change as they grow? Both the capacity for oxygen uptake and the oxygen requirements of animals changes with body size. This animation explains how body size affects oxygen supply and demand via changes in surface area to volume ratios and viscosity effects to provide a better understanding of changes in respiratory challenges during growth.

Awardwinning: Ecology: Oxygen & Cold Blooded Animals (short version)
 
02:00
Our animation won 1st prize at the Marie Curie Researchers Symposium 2011! How do changes in temperature affect the amount of oxygen that is available to cold-blooded, aquatic animals? Oxygen partial pressure, solubility and diffusivity all influence the amount of oxygen that is available to these animals. This short animation explains how these elements interact to provide a better understanding of oxygen supply and demand, showing that oxygen governs patterns in body size and species diversity.

Ecologie: Zuurstof & Koudbloedige Dieren
 
05:07
Hoeveel zuurstof beschikbaar is voor waterdieren is afhankelijk van de temperatuur. Deze animatie legt uit hoe de diffusiecoëfficiënt, de oplosbaar en de partiële druk van zuurstof varieren met temperatuur en daarmee hoeveel zuurstof er beschikbaar is als het water opwarmt. Met een beter begrip van de zuurstofbeschikbaarheid kunnen patronen in soortenrijkdom en lichaamsgrootte beter worden begrepen. Bovendien biedt dit mogelijkheden om de effecten van klimaatsverandering te voorspellen.

Contribution to famelab semifinale by Dr Verberk
 
03:09
In this 3 min video, I explain the challenge of breathing under water, how temperature affects the breathing of aquatic animals and how this offers an explanation for why it is advantages for aquatic animals to be larger in colder waters. This video was my contribution to the semi-finals for the famelab science communication competition.
