1. Heart and ventilation rate changes during tonic immobility in Ornate Tinamou (Nothoprocta ornata) and High Andean chicken (Gallus gallus) compared to Chilean Tinamou (Nothoprocta perdicaria)
University essay from Linköpings universitet/Biologi; Linköpings universitet/Tekniska fakultetenAbstract : Animals can show different responses to fear for example by playing dead when there is no possibility to escape. This response is called tonic immobility (TI) and is a well-established test of fear to evaluate fearfulness. Long durations of TI are generally considered as high levels of fearfulness. READ MORE

2. Validation study : HemoCue Hb 201 + as a tool in comparative physiological field studies on avian blood
University essay from Linköpings universitet/Biologi; Linköpings universitet/Tekniska fakultetenAbstract : Haemoglobin concentration is becoming a widely popular parameter to use to assess physiological condition within a broad range of species. Assessments of large populations would preferable be done in field to receive quick results and avoid confounding factors associated with transport of blood. READ MORE

4. Knockdown of the ERK pathway using siRNA in cultured chicken cardiomyocytes
University essay from Biologi; Tekniska högskolanAbstract : The ancient South American birds called tinamous (Tinamidae) have the smallest hearts known among birds and their cardiomyocytes have previously been shown to express significantly lower levels of the mitogen-activated protein kinase ERK compared to the more modern chicken (Gallus gallus). ERK is a well-known mediator of growth signalling in the heart, especially in hypertrophy. READ MORE

5. Cardiorespiratory responses upon increased metabolism in the Ornate Tinamou, Nothoprocta ornata
University essay from Biologi; Tekniska högskolanAbstract : The Bolivian Ornate Tinamou, Nothoprocta ornata, lives higher than 3300 m above sea level and must constantly deal with a restricted availability of atmospheric oxygen, i.e., chronic hypoxia. Interestingly enough, the Ornate Tinamou has a small heart to body ratio, which implies a reduced ability in transporting oxygenated blood to the tissues. READ MORE
