Our results support the conclusions of Twainsonand suggest that government regulation and drug testing may be in order. Such a result would suggest the biological function of JCl- reabsorption. It would be very interesting to compare the relative amount of reabsorption in frogs active at temperatures where the effects on jumping performance occur versus those where it does not.
We had proposed that its effect might be an enhancement of activity of certain enzymes. We looked at temperature effects by carrying out the same experiments at a range of different ambient temperatures. At this time each frog was placed on an open floor and induced to jump 2 times by slapping the ground behind the frog.
In Rana pipiens reabsorption of JCl- will clearly lead to increased jumping ability which can be expected to improve its survival chances. The Union college biology lab reports of temperature: Why do hot lizards run faster?
Twainson expressed concern that the increased occurrence of doping with this drug in frog jumping contests may have dire consequences for the sport.
This result lead to a number of studies attempting to identify the advantage of reabsorption of this product. We also investigated the influence of temperature in modifying JCl- levels, which then induced changes in jumping performance.
However, there are differences between the species in how this effect appears. Is JCl- a frog muscle builder? Each frog was tested 10 times. Such a mechanism has been proposed for the action of the hormone gogetemall in the tree lizard Philanthropus fabricus Herpbrain and Phutz, If this is the case, we hypothesize that jumping distance will improve exponentially with temperature over a certain temperature range.
The results presented here also have serious implications for the use of JCl- in frog jumping contests. Frog jumping and drugs: This explains why no significant difference in jumping distance was observed at room temperature Fig.
Journal of Frog Kinesiology. We conducted the study on two different species to see if the effects observed were species-specific or more general in nature. Moreover we have recently found that use of JCl- compromises the health of our frogs.
This strongly suggests that improved jumping performance alone cannot account for the evolution of the general tendency of frogs to reabsorb this substance. JCl- and climbing ability in tree frogs.To be sure that you have a good understanding of your experiment, some educators suggest writing the introduction after you have completed the methods and materials, results, and conclusion sections of your lab report.

Comparative Vertebrate Anatomy class videos For the Spring term, Professor Kirkton’s Comparative Vertebrate Anatomy class made videos to convey the findings of a recently published Journal of Experimental Biology article. Compared to colleges of similar size, the range of courses offered at Union is exceptional – cell and molecular biology, neurobiology, bioengineering, plant and animal organismal biology, environmental biology, developmental biology, and ecology and evolutionary biology, to name a few.

Lab report #2 will summarize two weeks of labs and lab report #3 will report on 3 weeks of labs. The final lab report will also summarize 3 weeks of labs, but this lab will also serve to tie together the whole lab sequence.
