Departing from Hull

May 11, 2026
WDG

Hull was a departure point for many people across the sea, and also a departure point for me in my life and academic career!

Last weekend I returned to Hull to catch up with friends from my undergraduate days for the first time in more than 20 years! We were all based at the University of Hull “Ferens Hall” hall of residence for our first year (1995-1996), following this we shared houses in the streets around the university main campus. Over the last twenty years later we have all headed off along different an meandering paths in life, but catching up with everyone felt very normal. A testement to the solid friendships developed during those three years at Hull. The reunion was helped along by some Manchester Bitter and Yorkshire stout (not avaliable on tap in the Netherlands) and some fine locations in the redeveloped Hull marina area.

Whilst at Hull, as well as making friends, I studies for a BSc (Hons) in Physical Geography. During my degree I got my foundations and inspiration for exploring past environmental change from a range of great lecturers, memorably including:

Steve Ellis (soil science; and author of the then recently published Ellis & Mellor [1995] text book),
Barbara Rumbsy (past river systems; who – if I remember the rumour correctly – left academia to run a tea shop in the Lake District – was this true?),
Martyn Pedley (sedimentology; double carbonate sedimentology on a Friday afternoon was typically punctuated by a swift trip to the Student Union bar [but we always went back]),
James Brasington (hydrology; who I remember running after down a crowded corridor for some reason long forgotten), and
Jane Bunting (palaeoecology; who really set me on my academic path!).

As an undergraduate arriving in Hull in 1995 I could never have imagined that I would be in Amsterdam 30+ years later working as an academic. I hope that, as an academic today, I manage to convey the same energy and enthusiams for my subject as the lecturers I had at Hull did for me. Who knows where my students, staff, or I, will all be 30+ more years time, but I am sure things will change (and wierdly stay the same) just as much as they have (have not) over the last 30 years. I hope that the path is varied and interesting, and that more friendships and progress are made along the way. So on with the adventure…

Environments Through Time paper presentations

November 6, 2018
WDG

The 2018 edition of the University of Amsterdam masters course “Environments Through Time” is now up and running. The course sits at the interface between ecology, physical geography and archaeology and seeks to provide students with a better understanding of how long-term (>100’s years) datasets can provide insights in to past environmental change.

In the first week of the course the students had to present their ‘favourite’ paper in just three (3) minutes! Quite a challenge and lots of fun. This years selection of papers themed around:

mega-fauna extinctions (Bakker et al., 2016; Gill et al., 2009; van der Kaars et al., 2017),
impacts of human land use practices (Bitusik et al., 2018; Carson et al., 2014; Chepstow-Lusty et al., 2009; Gauthier et al., 2010; Tisdall et al., 2018), and
climatic drivers of vegetation change (Haug et al., 2001; Tierney et al., 2017; Tudhope et al., 2001).

For full list of papers presented see below.

In the second and third weeks (now ongoing) students get to deconstruct published chronologies and conduct time series analsis of multi-proxy datasets. Data for these excercises is frequently is extracted from databases such as Neotoma, Pangea, NOAA – paleoclimatology datasets database and the Global Charcoal Database – which shows the importance of these open access databases for developing effective research led eductation, as well as pushing forward to frontiers of research.

Environments Through Time is taught in English, delivered by myself (William Gosling), Crystal McMichael and Milan Tunissen van Manen and currently has 31 registered students from MSc Biological Sciences and MSc Earth Sciences degrees.

Environments Through Time – weeks 2 & 3

Britte reconfiguring the chronology for Lake Pata

The second and third weeks of the Environments Through Time course at the University of Amsterdam has focused on obtaining practical experience of developing chronologies, analyzing multi-variate data-sets, and conducting time series analysis. The focus of the course has been on Quaternary environmental change, however, the skills learnt can be applied to almost any time-scale so long as you have time control points you want to tie together, and multiple things you can track changing through that time.

Over the two week period the students worked on a previously published paper that they had selected that contains: (i) chronological information (at least 3 control points), and (ii) multiple variables that change through the time series (at least 9 variables). In week two they deconstructed the chronologies and generated their own revised versions. For example students have (re-)calibrated radiocarbon dates, made different decisions on dates to include/exclude, and used different approaches to constructing the age vs. depth model, e.g. contrasting linear point-to-point vs. Bayesian methodologies. In week three they have taken the data-set(s) associated with their paper and re-evaluated it in light of the revised chronologies using cluster analysis, ordination techniques, and wavelets.

The joy of wavletes

Through this exercise students have gained experience of how to critically assess scientific literature and gained an appreciation of where re-analysis of data-sets can (and cannot) make a difference. Personally I have be delighted with the high level of engagement and enthusiasm for the material and have been excited to have a chance to delve into literature that I would not otherwise be aware of.

International Biogeography Society Conference – Bayreuth, Germany

January 28, 2015
Erik de Boer

International Biogeography Society
7th biennial conference
January 8 – 12, 2015
University of Bayreuth, Germany
Report by Erik de Boer

Two weeks ago I attended the biannual International Biogeography Society (IBS) conference in Bayreuth, together with 600+ other people from more than 50 different countries. This IBS conference, my first IBS meeting, proved to be an exciting event during which I met scientists from many different disciplines and heard talks on cutting-edge biogeographical research.

The IBS conference was held in the Bavarian city of Bayreuth, in the middle of the biodiverse landscape of Upper Franconia. This landscape provided the training ground for Alexander von Humboldt, the founder of the field of biogeography. The 4-day conference included a wide variety of symposia and many, many posters. The conference dinner in the German Steam Train Museum was highly memorable. The conference was closed by a lecture from Daniel Simberloff, once a doctorate student of Edward O. Wilson, who received the Wallace Award for his outstanding contributions to invasion ecology.

I had a talk in the plenary symposium of ‘Ecosystem response to past climate change’, organized by David Nogués-Bravo and Francisco Rodríguez-Sánchez. The symposium covered the dangers of climate change to biodiversity and tried to assess if the range and rate of adaptation, migration, persistence, or extirpation, that are registered in deep-time records, palaeorecords, and the recent past, are adequate responses for predicted climate change in the future. I addressed this issue from the point of view of a small remote island, where migration is obviously a limiting factor. I showed how I reconstructed climate and its effect on island biota during the last 40,000 years using long-term palaeoecological records from Mauritius (de Boer et al, 2013 & 2014). These records show that different climate regimes result in different ecosystem response to climate change in the past. Local extirpation or population collapse of larger vertebrates was a natural phenomenon in the lowlands of Mauritius due to frequent climate extremes (I will discuss this in more detail in my next blog; de Boer, 2015). Despite these population collapses, island biota have always (in the timeframe of my records) survived natural climate change. Therefore, my take home message was not to focus on the effects of (future) climate change alone. Other key components of global change, such as invasive species and habitat destruction, are more imminent threats to the biodiversity of many islands.
