Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Ecology
  • Biochemistry

The scientist’s investigation covers issues in Anatomy, Respiratory system, Respiration, pCO2 and Animal science. His study in Anatomy focuses on Aquatic respiration in particular. The Respiratory system study combines topics in areas such as Bohr effect and Fick principle.

His Respiration research incorporates elements of Ventilation/perfusion ratio, Lung volumes, Lung and Breathing. His pCO2 study is related to the wider topic of Internal medicine. His Animal science study combines topics from a wide range of disciplines, such as Pulmonary respiration, Amphiuma tridactylum, Rainbow trout and Salmo.

His most cited work include:

  • Adaptation to hypoxia by increased HbO 2 affinity and decreased red cell ATP concentration. (201 citations)
  • REGIONAL DISTRIBUTION OF CIRCULATING BLOOD DURING SUBMERSION ASPHYXIA IN THE DUCK. (195 citations)
  • Gas transport and oxygen storage capacity in some pinnipeds and the sea otter. (179 citations)

What are the main themes of his work throughout his whole career to date?

His primary areas of investigation include Anatomy, Internal medicine, Animal science, Respiratory system and Respiration. His Anatomy research includes elements of Blood flow, Blood pressure, Bohr effect, Circulatory system and Arterial blood. His work carried out in the field of Bohr effect brings together such families of science as Zoology, Oxygen–haemoglobin dissociation curve and Ecology.

He has researched Internal medicine in several fields, including Endocrinology and Cardiology. His Animal science study incorporates themes from Hemoglobin, Rainbow trout and Oxygen uptake. His study in Respiration is interdisciplinary in nature, drawing from both Breathing, Tidal volume, Lung and Respiratory rate.

He most often published in these fields:

  • Anatomy (44.07%)
  • Internal medicine (22.03%)
  • Animal science (20.34%)

What were the highlights of his more recent work (between 1983-2017)?

  • Anatomy (44.07%)
  • Respiration (18.64%)
  • Animal science (20.34%)

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Anatomy, Respiration, Animal science, Circulatory system and Internal medicine. His Anatomy research includes themes of Blood flow, Lung, Pulmonary artery and Gill. His Respiration study combines topics in areas such as Zoology, Human physiology, Breathing and Respiratory rate.

His research integrates issues of Hypoxia, Oxygen uptake, Rainbow trout and Tidal volume, Respiratory system in his study of Animal science. His Circulatory system study also includes fields such as

  • Aorta which is related to area like Pulmonary shunt, Ductus arteriosus and Shunt,
  • Ventricle that intertwine with fields like Sinus venosus,
  • Blood pressure most often made with reference to Hemodynamics. His Internal medicine research is multidisciplinary, incorporating elements of Endocrinology and Cardiology.

Between 1983 and 2017, his most popular works were:

  • An automated swimming respirometer (147 citations)
  • Gravitational haemodynamics and oedema prevention in the giraffe (136 citations)
  • Circulation and respiration in lungfishes (Dipnoi) (100 citations)

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Ecology
  • Biochemistry

His main research concerns Anatomy, Animal science, Arterial blood, Hemodynamics and Circulatory system. His work investigates the relationship between Anatomy and topics such as Blood flow that intersect with problems in Siphon, Pressure gradient and Human physiology. He interconnects Hemoglobin, Rainbow trout, Washout, Smooth muscle and Vasodilation in the investigation of issues within Animal science.

His Arterial blood research includes elements of Toad, Bufo and Control of respiration, Breathing, Respiration. His Hemodynamics research integrates issues from Vasoconstriction, Blood pressure, Orthostatic vital signs and Perfusion. His Circulatory system research is included under the broader classification of Internal medicine.
