![Impacts of climate change on mosquito-borne diseases](http://daphnia.ecology.uga.edu/drakelab/wp-content/uploads/2024/03/Dahlin_pub_image-470x140.jpg)
As the planet warms, the behavior and distribution of mosquitoes is expected to change. But it’s not just about the mosquitoes; it’s also about the…

As infectious disease modelers, one of the greatest challenges we face is in accurately reflecting the complexities of transmission, particularly human behavior. Important factors we…
![Nest temperature and sex ratios in a crocodilian](http://daphnia.ecology.uga.edu/drakelab/wp-content/uploads/2020/05/HATCH_sm-470x140.jpg)
Global shifts in temperature are yielding widespread impacts across diverse ecosystems and certain species are especially vulnerable to these changes. In particular, many reptiles –…
![Multiscale model of regional population decline in little brown bats due to white‐nose syndrome](http://daphnia.ecology.uga.edu/drakelab/wp-content/uploads/2019/08/Geomyces_destructans_1-470x140.jpg)
The introduced fungal pathogen Pseudogymnoascus destructans causes White-nose syndrome in North American bats, putting some populations at risk for extinction or extirpation. The severity of…
![Factors influencing the detectability of early warning signals of population collapse](http://daphnia.ecology.uga.edu/drakelab/wp-content/uploads/2015/05/daphnia-magna1-470x140.png)
Early warning signals of critical transitions arise due to critical slowing down as a dynamical system approaches a tipping point. Extinction of a biological population…
![Phase transitions in salmon population dynamics](http://daphnia.ecology.uga.edu/drakelab/wp-content/uploads/2014/04/armstrong-salmon-470x140.jpeg)
Early warning signals for critical transitions have now been described from a number of ecological and geophysical systems. Most of these signals reflect a dynamical…
![Are extinction time distributions scale free?](http://daphnia.ecology.uga.edu/drakelab/wp-content/uploads/2014/02/daphnia-pulicaria-258x140.png)
What is the shape of the probability distribution of population extinction times? We followed the dynamics of more than a thousand experimental populations of Daphnia…
![Timescales of extinction over a patch size gradient](http://daphnia.ecology.uga.edu/drakelab/wp-content/uploads/2013/07/longtubes_shadow-470x140.png)
Background Theory predicts that the logarithm of mean extinction times will scale with patch carrying capacity. Although previous results are consistent with this theory over…
![Distribution of extinction times](http://daphnia.ecology.uga.edu/drakelab/wp-content/uploads/2013/07/DPu-tubes_shadow-470x140.png)
Background Few experimental or observational datasets are available from which to learn about the stochastic properties of extinction. Particularly, there have been no large studies…
