African Bioacoustics Community Conference
Tuesday, May 8, 2018 - 08:30

SEEC researcher, Tess Gridley, is organising a conference in Cape Town on all aspects of bio-acoustic research this December.

Further information about the conference can be found on the website, Facebook page or by emailing africanbioacoustics@gmail.com

Positions available in our Seasonality in the Cape project
Thursday, April 19, 2018 - 10:30

We seek several students, a postdoc and a research technician to join our NRF ACCESS funded “Seasonality in the Cape” project exploring the impacts of changes in rainfall seasonality on vegetation and birds in the global biodiversity hotspot of the Greater Cape Floristic Region (GCFR). Changes in seasonality of rainfall might have profound impacts for this highly diverse and endemic vegetation in the only winter-rainfall dominated region of sub-Saharan Africa.

Our project will combine large-scale outdoor experiments with remote-sensing and citizen science data across the GCFR to tackle this issue. Opportunity exists for the development of key skills in: field experimental approaches, collecting and analysing physiological, demographic and community data, ecological remote sensing and data analysis. All student positions start 1 July 2018 and the post-doc and technician position 1 June 2018.

See the attached advert for more details.

Congratulations to Danielle on her MSc graduation
Tuesday, April 17, 2018 - 15:15

Congratulations to Danielle Boyd who graduated with a M.Sc. in Statistical Ecology this month. We are proud of you Danielle!

The title of Danielle's thesis is "Fishery, population dynamics and stock assessment of geelbek (Atractoscion aequidens), a commercially important migrant fish species off the coast of South Africa"

You can read the abstract of her thesis in the full news piece...

Tackling multivariate analysis of ecological data in a new way…Thanks David!
Thursday, February 1, 2018 - 06:15

In January SEEC hosted David Warton a Professor and Australian Research Council Future Fellow from the University of South Wales.

David champions the movement away from traditional methods of exploratory multivariate analyses to more predictive and testable model-based analyses in an effort to maintain the integrity of the data during analyses. To this end he has developed the mvabund R package.

While at UCT, David offered a model-based multivariate statistics course attended by 35 ecologists and statisticians from all over South Africa. This course challenged our thinking about popular multivariate methods and introduced new methodologies which will hopefully become more common in ecology. We have learned a lot and hope for many more future interactions with David and his students. Watch David’s recent Stats Department seminar HERE.

Data for Climate Action win!
Tuesday, November 14, 2017 - 10:30

Congratulations to Jasper and his team, who won one of the 3 thematic awards at the Data for Climate Action (D4CA) challenge award ceremony at COP23!

D4CA is a competition under the UN Global Pulse programme. Teams were asked to "use big data and data science to catalyse action on climate change". There were 97 teams involved so to be among the winning ones is a great achievement.

The team's submission developed a tool for detecting vegetation changes in near real-time. You can read more about the approach here.


The submission was led by Jasper, Adam Wilson and Glenn Moncrieff, with contributions from a number of other SEEC people - Zaza, Etienne, and Vernon. Well done to everyone!

Course - Model-based multivariate analysis of abundance data using R
Thursday, September 14, 2017 - 09:15

In January 2018 SEEC will be hosting David Warton who will be holding a 5-day course on modern multivariate techniques, with a special focus on the analysis of abundance or presence/absence data.

New paper: Learning from single extreme events
Wednesday, May 10, 2017 - 15:45

Check out a new SEEC-authored paper recently published in the Philosophical Transactions of the Royal Society B.

As the Earth's climate changes, extreme climatic events such as heat waves and floods are becoming ever more common. However, these events are still relatively rare and infrequently observed. This often leads to the situation where researchers have data for only one extreme event, but they are convinced that this event has had a large effect on the organism or system on which they are working.

One might think that observing a single event is not amenable to analysis. However, Res Altwegg, Birgit Erni, Vernon Visser (all from SEEC) and Liam Bailey (Australian National University) show that this is not always the case and that observing one extreme event is not the same as having only one data point. In this paper they provide guidance for how, and under which conditions, one can analyse single extreme climatic events.

New paper: A hotter and drier Fynbos is reducing biodiversity
Tuesday, April 18, 2017 - 14:15

Jasper Slingsby, a SEEC honorary research associate and SAEON biodiversity scientist, has just published a paper on how climate change is leading to biodiversity decline in the Fynbos.

In the longest running permanent vegetation plot study in the Fynbos, Jasper and his co-authors found that an increasing frequency of consecutive dry and hot days is leading to lower plant diversity as a result of higher plant mortality in the first year after fires. They also found that there is a legacy effect of plant invasions, even after these are cleared, as plots that had previously been invaded exhibited a decline in plant diversity over time.

You can read his paper here.

Paper in Science!

FIELD ASSISTANTS NEEDED
Wednesday, February 8, 2017 - 12:00

We are looking for committed and hardworking candidates to help with field work from MAY to SEPTEMBER 2017. Fieldwork involves LOTS OF HIKING! You will visit sample sites in the mountains of the Cape Peninsula in order to set up acoustic arrays to record calling frogs. Candidates must be able to work full days in the field.
 

MSc project on modelling frog distribution
Wednesday, February 8, 2017 - 11:45

SEEC has an MSc bursary available to work on modelling range-wide abundance patterns of moss frogs
(Arthroleptella lightfooti) using acoustic monitoring data. We are looking for a student with a background in biology
or environmental science with a strong quantitative (statistical or mathematical) angle or statistics students with a
strong interest in biology or environmental science.
 

Lightfoot’s moss frogs occur on the Cape Peninsula and their distribution is likely determined by climatic factors such
as availability of water. Are the same factors also affecting the density of this species where it occurs? And how is it
likely to be affected by climate change? We have developed new statistical methods for estimating frog densities from
acoustic data (see http://john.measey.com/aSCR) and aim to get density estimates of moss frogs across their range.
