How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I'm a Postgraduate Research Student at the National Oceanography Centre and Natural History Museum. My research is focused the evolutionary and ecological consequences of tropicalisation across marine environments. My masters research at the University of Leeds was focused on quantifying herbivory pressure across tropical and subtropical reefs of Japan, in relation to tropicalisation. My other research interests range from environmental sustainability to palaeoecology and palaeobiology.
Biotic interactions and community structure are seldom examined in mass extinction studies but must be considered if we are to truly understand extinction and recovery dynamics at the ecosystem scale. Here, we model shallow marine food web structure across the Toarcian extinction event in the Cleveland Basin, UK using a trait-based inferential mode...
Tropicalization is rapidly restructuring subtropical marine communities. A key driver for tropicalization is changes in herbivory pressure that are linked with degrading ecosystem stability. Consequently, subtropical algal beds are being displaced by climate-mediated colonisation of coral communities. This process is thought to be aided by the elev...

I'm using (or trying to use) Arlequin on Windows to run an AMOVA on some haplotypic data (mitochondrial genetic marker). I'm pretty certain the data is set up correctly - it reads in correctly and the groups are assigned correctly too. When I go to the "Settings Tab" and select the AMOVA analysis, I press start - nothing happens. No console pops up to make it seem like something happened, and no file is generated in the working directory.
I set up the file using the tutorial from the Banta Lab (https://sites.google.com/site/thebantalab/tutorials#h.c6sq8o45ens6) , I then followed the AMOVA set up (difference is I have haplotypic rather than genotypic data). When I noticed that nothing happens when I pressed start, I tried using the sample data from the tutorial but I am facing the same issue.
Has anyone had this problem before?
- Documenting tropicalisation on the rocky shores of Baja California Penninsula - Uncover the changes in interspecific interactions arising from the tropicalisation by coastal tropical predators. - Evaluate the consequences of tropicalisation at the genetic level of gastropod populations.
The aim of this project is to quantify and compare herbivory pressure exerted by fish and sea urchins on coral reefs, across a latitudinal gradient.
A comparison of diversity and functionality of coral-associated invertebrates within the range shifting subtropical coral reef communities of western Japan. 1. Determine differences in community diversity, structure, and functional composition of coral-associated invertebrates at tropical and subtropical sites using fine-scale visual surveys and eDNA. 2. Uncover to the effectiveness of eDNA to quantify the hidden community diversity of invertebrates that live within poleward expanding coral reefs. 3. Compare community diversity data to a broad scale 20-year community dataset to examine for temporal changes caused by rising sea surface temperatures.
