Investigating Distribution and Abundance 

the abundance of an organism is how many individuals you find in an area 

abundance can be estimated by counting the number of individuals in samples taken, these resulst then need scaling up for the total area 

the distribution of an organism is where an organism is found in a habitat

you can study the distribution by: 

measure how common an organism is in two sample areas  using quadrats and compare them  or 

study how the distribution changes across an area e.g. by placing quadrats across a transect 

sampling methods

pooters are jars that have rubber bungs sealing the top and 2 tubes stuck through the bung
