The WordPress.com stats helper monkeys prepared a 2015 annual report for this blog.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 11,000 times in 2015. If it were a concert at Sydney Opera House, it would take about 4 sold-out performances for that many people to see it.

Past environmental change on Mauritius: Unknown macro-fossils

Unknown macro-fossil JdK-type2

Unknown macro-fossil JdK-type2

Past environmental change on Mauritius has been the focus of research with the Palaeoecology & Landscape Ecology group at the University of Amsterdam (UvA) for a number of years. This research has been lead by Erik de Boer and Henry Hooghiemstra and has already resulted in a number of key publications on the environmental history of the island (de Boer et al., 2013, 2014, 2015). One current past environmental change research project working on Mauritius is being undertaken by Jona de Krui; a student within the UvA BSc Biology program supervised by myself and Erik. Jona’s is working on a study site (modern day swamp) on the north-east of the island and is focused on improving our understanding changes in the:

  • depositional environment (loss-on-ignition analysis),
  • fire activity (macro-charcoal analysis), and
  • vegetation (macro-fossils) over the last c. 1000 years.

Jona has now completed the analysis of all his samples and we are currently collating the data sets; however, a number of the macro-fossils which he has discovered remain unidentified. Below are images of the unknown macro-fossils if you have any suggestions on identifications please comment, or get in touch directly.

BES annual meeting: Top talks

I am just back from a fabulous British Ecological Society (BES) annual meeting in Edinburgh. Both the city and the science were interesting and exciting. The Science Slam was certainly my highlight “fringe” event and I believe all the slams will be avaliable to view soon on the BES Youtube channel. But you can watch the winner, Rosie Woodroffe, now…

Of the many great science talks I would like to highlight just four here which I found particulalry interesting, by: Stephen Prentice (Queen’s University Belfast), Althea Davies (University of St. Andrews), Tom August (Cente for Ecology & Hydrology), and Kimberly Simpson (University of Sheffield).
