How can species respond to environmental change?
If you’re a somewhat avid (or even cursory) reader of The G-CAT, you may remember my wrap-up post at the conclusion of my PhD in 2020 which described the various chapters of my thesis. Well, I’m pleased to announce that data chapter 2 of that thesis – on the comparative phylogeography of two threatened Australian freshwater fishes – has just been published in the journal BMC Ecology and Evolution. It’s a pretty complex paper which tackles genetic diversity, phylogenetics, demographic history, species distribution models and how these interact together to understand the evolutionary history of these species in a comparative framework. Feel free to check it out (it’s open access and free to read!) here.
From genotype to phenotype
One fundamental aspect of conservation and evolution research is the implicit connection between genetic variation, phenotypic characteristics, and their influence on Darwinian fitness. Genetic diversity underpins many aspects of the adaptive potential of a population, and many of the fundamental concepts of the field rely on the assumed connection between genetic and phenotypic characteristics. But this connection is neither straightforward, nor always predictable.
Welcome to 2022! Boy, the last two years have not been overly kind…but here’s hoping that things (globally) will improve! Here, I thought it would just give a little recap about what’s been happening on my end, and what to expect from me (and The G-CAT) in 2022.
The roles of aridification and sea level changes in the diversification and persistence of freshwater fish lineages
The process of publishing science is a lengthy one – there are many rounds of revisions, assessments, and review required before a paper can be published. With that, I’m very proud to announce that the first paper from my PhD has recently been published in the journal Molecular Ecology. This paper is a collection of a lot of complex analyses, and addressing some relatively complicated biogeographical questions, so I’ve decided to provide a simplified summary here.
Revisiting Piñata Island
Every now and then, my gaming habits tend to take a bit of a wander down memory lane. Of late, that means cracking out one of my classic faves – the life simulation and “collectathon” Viva Piñata by Rare. Originally released in 2006, with successor (expanded version, essentially) Viva Piñata: Trouble in Paradise released in 2008, the game essentially involves creating a lavish garden to attract wild piñata-like animals. Although a little light on plot, the main goal is to entice these wild creatures (Wilds) to stay in your garden (becoming Residents), to later be sent off to parties across the globe. Trouble in Paradise boasts a roster of 88 different species of Piñatas to collect, as well as a variety of fruiting trees, plants, and flowers to grow.
