were sleeping; in these mosquitos were observed various stages of the development of the parasite. From such a study, considering the quantity of material used, we might expect, as indeed turned out to be the case, noteworthy results. Contemporaneously, mosquitos were studied, which were caught in stables and poultry yards, which, deriving their nourishment from the blood of birds and domestic ...
متن کاملIn vivo MR Imaging and MR Spectroscopy in Marine Biology
In vivo MR imaging (MRI) and MR spectroscopy (MRS) have gained broad significance in experimental medical and pharmacological research. MR imaging and spectroscopy tools have been used with standard laboratory animals to answer numerous physiological questions. MR investigations have become routine for studying brain and cardiac (patho)physiology, and with the development of high-speed and high...
متن کاملGeneral Zoology
This little book contains a surprisingly large number of good descriptions of experimental techniques, presented with enough theory to make them intelligible. The chapters deal with blood, the circulation, respiration, muscle, peripheral nerve, the physical basis of body heat exchanges, and electronics in physiology. The methods are all physical rather than chemical, and such topics as electro-...
متن کاملZoology: The Walking Heads
An analysis of Hox genes reveals that the body of the adorably weird tardigrades is essentially a truncated front end. This illustrates that loss and simplification are a hallmark of the evolution of animal body plans.
متن کاملReprinted from PHYSIOLOGlCAL ZOOLOGY
Oxygen consumption, heart rate, and thermal tolerance were measured in week-old embryos of Heermann's gull ( h r u s heermanni). Heart rate and oxygen consumption are temperature independent between 30 and 40 C and average 120 beats/min and 1.87 cm3 Ot/(egg-h). Below 30 C, these rate processes become strongly temperature dependent, and the heart stops beating when cooled to 7-13 C. The beat rec...
