Eco 101: Exponential Growth & Decay

Posted 27 Jan 2017 / 0

Different rates of positive and negative growth create different population trajectories over time In biology, a population is a group of organisms that belong to the same species and occupy a defined land area (or volume of air or water). These populations have the tendency to grow and shrink over time. This is because the rate at which members of Read More

My first “Breeders, Propagators, & Creators” talk: next Friday at St. Francis College

Posted 04 Dec 2015 / 0

Next Friday, December 11th, at 3 pm I will be delivering a talk at St. Francis College entitled “Highly-creative baby-breeding idea propagators: what human (re)productive choices mean for the future of our species“. The talk is a synopsis of a large section of my book-in-progress Breeders, Propagators, & Creators: Culture, Biology, and the Future of Human Evolution. Read More

Carrying capacity — but not growth rate — varies with habitat quality (at least for moose)

Posted 17 Aug 2015 / 0

Ecosphere “Characterizing demographic parameters across environmental gradients: a case study with Ontario moose (Alces alces)” What I find interesting about this study — besides its unprecedented investigation of something that would seem pretty critical to basic conservation efforts — is what was and was not intuitive in its findings. Moose have higher carrying capacities where Read More
