GAReetings @biotweeps! Let's talk about ecology & conservation of populations at the edge of a species' range! Questions welcome! #BTCon17

Peripheral populations occur @ edge of a species' range; may experience diff conditions from core populations (near range center) #BTCon17

We wanted to know how peripheral populations differ from core populations, using an ancient fish as a model species: Spotted Gar! #BTCon17

Spotted Gar, native to Eastern N.America, has been around for ~15-20 million years; an apex predator, mainly eats 🐟🦐, sometimes 🐞🐸 #BTCon17

Unfortunately, gars often carry bad reputation as "trash fish" often killed and tossed on shoreline. Hope to change that attitude! #BTCon17

Peripheral populations of Spotted Gar occur in #GreatLakes basin, disjunct from core popns in Mississippi Riv (et al) basin. #BTCon17

How do populations differ? BIG latitudinal distance north-south; length of growing season shorter up north...Winter is Coming! #BTCon17

Some organisms adapt to shorter growing season by evolving faster growth rate, example of "countergradient variation" 📷Gulo gulo! #BTCon17

Countergradient variation: genetics compensate for environmental influence on phenotype. Ex: faster growth w/ short growing season #BTCon17

Results: Peripheral population gars grew significantly larger/faster than core population! Increase in weight +220% vs +60%!!! #BTCon17
