L19-logical fallacies, models, oxygen tolerance Flashcards
climate change effects
lack of study in may areas of the world
places we study may not be representative of other parts of the globe
may no represent future environment
two types of models?
• Phenomenological models – A function is used to describe an underlying biological process (often the function is based on empirical data) • Mechanistic models – Details of processes taking place at another level are explicitly tracked (empirical data not required)
strengths and and weakness of Phenomenological models?
is often very accurate
requires observations can’t answer questions about things that have not been observed eg. bee flying on another planet
should not extrapolate beyond data
strengths and and Mechanistic of Phenomenological models?
can come to wrong conclusion if assumptions don’t apply e.g bumblebees can’t fly
can predict things that have not happened eg. flying on another planet(out of sample predictions)
useful for climate change
Thermal performance
looks like a negatively skewed bell curve
varies with level of organisation
higher level organisation has narrower range of temperature
prokaryote better heat tolerance hyer than multicellur
approach to studying effect of climate change
different ways of modelling
if we want to understand processes need to understand mechanism such as reproduction and growth
xygen capcity thermal tolerance hypotheisis
decreasesing efficentcy with to much warmth less energy for reproduction
What is pejus
range of conditions organism can cope with
OCLTT physicocal and ecologically vaild?
does seem to be the case
made it way into ipcc
warming effect on samon
samon that migrate further have better aerobic performance
performance match temps experiance
what is climate change effects temperature
The decline effect
intially massive effect
then its small effect
actully its complicated
often difficult to replicate
happens cause we draw large conculsions on little data intially
Logical fallacies tone policing
have to be polite, don’t critize to much, “don’t confront collarberate”
Logical fallacies false dilemma fallacy
if you don’t have a better hypothesis don’t challanage this one
