The BES Quantitative Ecology SIG: Who We Are, What We Do and What to Look Out for at #EAB2017

Post provided by Susan Jarvis and Laura Graham

Ecologists are increasingly in need of quantitative skills and the British Ecological Society Quantitative Ecology Special Interest Group (QE SIG) aims to support skills development, sharing of good practice and highlighting novel methods development within quantitative ecology. We run events throughout the year, as well as contributing to the Annual Meeting and providing a mailing list to share events, jobs and quantitative news.

Ecology Hackathon

The run up to the Ecology Across Borders joint Annual Meeting in Ghent this month is an exciting time for the SIG as we look forward to catching up with existing members as well as hopefully meeting some new recruits! Several of our SIG committee members will be in attendance and if you’ve been lucky enough to get a place at the Hackathon on the Monday you’ll meet most of us there. The Hackathon has been jointly developed by us and two of our allied groups; the GfÖ Computational Ecology Working Group and the NecoV Ecological Informatics SIG and is being sponsored by Methods in Ecology and Evolution. We’ll be challenging participants to work together to produce R packages suggested by the ecological community. You can see the list of package suggestions here. If you weren’t able to book a place at the Hackathon, but are interested in writing your own packages, you may be interested in the new Guide to Reproducible Code from the BES. Continue reading

Tracing New and Old Resources in Estuarine Ecosystems

This week, more than 150 events along the US shores will celebrate estuaries and educate the public and policy makers of the many benefits we get from healthy and thriving ecosystems. But why do we need to pay more attention to estuaries?

Estuaries are biological hotspots and by far the most productive ecosystems on our planet. The shallow waters where streams and rivers meet the sea often harbour a rich terrestrial and aquatic flora and are home to many animals. They’re important feeding and reproduction areas for a diverse array of wildlife such as birds and fish, which can include both freshwater and marine species. A large portion of the world’s marine fisheries today depend on the ecosystem services of estuaries; it has been estimated that well over half of all marine fishes develop in the protective environment of an estuary. Historically, humans have been attracted to these large expanses of shallow water that could sustain their basic needs. Nowadays, these estuaries also have economic value as recreational and touristic destinations as for example fishing, boating and swimming spots.

However, our understanding of how estuaries function and sustain this amount of biodiversity is limited. As is the case for most ecosystems on our planet, estuaries are under increasing pressure from human activities. Estuaries are subjected to intensive land reclamation and developments like harbours and aquacultural farms. They also receive excessive amounts of of nutrients, soil and organic matter from intensive farms and urban landscapes via small streams and large rivers. These stressors are accentuated by environmental changes such as sea level rise, increasing water temperatures and extreme weather conditions causing droughts and flooding. Continue reading

Valuing Nature the Interdisciplinary Way

Post provided by Graziella Iossa

Before I started my NERC Valuing Nature Placement in April 2017, I’d never done interdisciplinary work. I had been thinking about it for a while though, when I read on Twitter that the Valuing Nature Programme were launching their placement scheme for 2017. I had already been in touch with my prospective hosts – Hilary Graham, Department of Health Science, and Piran White, Environment Department, both at the University of York – but the launch of the scheme galvanised our interest. We put together our application and were delighted to receive funding. So, what is that we set out to do?

Valuing Nature

Piran, Hilary and I had already been talking about projects focusing on knowledge transfer, particularly around collaborative work to tackle antimicrobial resistance. Valuing Nature was the perfect fit for what we wanted to do. The programme aims to further our understanding of nature in valuation analyses and decision making by building an interdisciplinary research community capable of working across the natural, biological and social sciences, as well as the arts and humanities. Interdisciplinarity is integral to the programme. Continue reading

Listen Up! Using Passive Acoustic Monitoring to Help Forest Elephant Conservation

Heard but not seen, populations of forest elephants (Loxodonta cyclotis) are rapidly declining due to ivory poaching. As one of the largest land mammals in the world, this species is surprisingly difficult to observe in the dense forests of Central Africa, but their low frequency rumbles can be recorded. With the autonomous recording afforded by passive acoustic monitoring (PAM) though, we have a window onto forest elephant ecology and behaviour that’s providing data critical to their conservation and survival.

The diverse ways that PAM can contribute to conservation outcomes is growing and while still underappreciated, the availability of relatively inexpensive recorders, increased power efficiency, and powerful techniques to automate the detection of signals have led to an explosion in use. In 2007 there were only about 20 published papers using PAM techniques, but since then over 400 papers have appeared in peer-reviewed journals.

Essentially, PAM is the automatic recording of sounds in a given environment, often for long periods. The trick, and often greatest challenge, is to find the signals of interest (bird calls, elephant rumbles, gunshots) within the recordings. With these signals we can quantify abundance, occupancy and spatial or temporal patterns of activity. Particularly in landscapes or ecosystems where visual observation is difficult (e.g. oceans, rainforests, nocturnal environments) PAM may be uniquely capable of delivering informative and unbiased data. Because PAM is a relatively new method but of considerable interest across the disciplines of ecology, behaviour and conservation, there is huge interest in refining the sampling and statistical methods needed to deal with the peculiarities of acoustic data.

At Last, a Paleobiologist is a Senior Editor for Methods in Ecology and Evolution!

Post provided by Lee Hsiang Liow

An Asian, female Senior Editor under 45? Progressive! I have loved Methods in Ecology and Evolution since it appeared in 2010 and am thrilled to have been selected to join Rob, Bob and Jana to help with the journal’s continued development.

OK, so you want to know who the new Senior Editor on the MEE block is.  I’m just another scientist, I guess. On the outside, we look different but on the inside, we’re all the same. (OK, perhaps we are a little different, even on the inside, but that makes life and research interesting, right?)

Here’s my academic life history: I did my Bachelors thesis on the systematics/phylogenetics of an obscure group of marine pulmonate slugs with one of the greatest Icelandic biologists I know, Jon Sigurdsson, at the National University of Singapore. I followed this up with an almost-half-year stint at the Museum of Natural Science in Berlin as a “nobody”, digitizing data. Then I won the academic lottery and headed up to Uppsala to do my masters in conservation biology on tropical pollinator diversity, (un)supervised by two amazing supervisors that never met each other, the late Navjot Sodhi (National University of Singapore) and Thomas Elmqvist, now at Stockholm University.

The Global Pollen Project is a new, online, freely available tool developed to help people identify and disseminate palynological resources. Palynology – the study of pollen grains and other spores – is used across many fields of study modern and fossil vegetation dynamics, forensic sciences, pollination, beekeeping, and much more. This platform helps to facilitate cross/multi-disciplinary integration and discussion, outsourcing identifications, expertise and the sharing of knowledge.

Pollen’s Role in Plant Conservation

Successful conservation of rare, threatened, and valuable plants is dependent on an understanding of the threats that they face. Also, conservationists must prioritise species and populations based on their value to humans, which may be cultural, economic, medicinal, etc. The study of fossil pollen (palaeoecology), deposited through time in sediments from lakes and bogs, can help inform the debate over which species to prioritise: which are native, and when did they arrive? How did humans impact species richness? By establishing such biodiversity baselines, policymakers can make more informed value judgements over which habitats and species to conserve, especially where conservation efforts are weighted in favour of native and/or endemic flora.

A few leading reasons for going to a conference are: to present your work and get feedback on it, to find out what others are doing, to meet collaborators and to network. But a conference can also be a great setting for generating completely new ideas. I find that conferences are one of my most likely places for a “eureka moment”.

Surrounded by researchers working on a range of different problems in interesting and often original ways, I’m encouraged to think about things from a different angle. Idea generation is perhaps one of the main benefits of going to a conference – but is the typical conference format is the best way to facilitate that? Or does it focus too much on giving researchers a platform to report on previous research ideas? Continue reading

How Should Biologists Measure Climate Change?

Post provided by Christopher Nadeau

Climate change could cause the extinction of one in six species and change the abundance and distribution of those that remain (Urban, 2015). This doesn’t necessarily mean that one in six species in your backyard will go extinct though. Climate change impacts will vary greatly around the globe, with some regions seeing disproportionate effects.

The degree to which climate change will affect species in your region depends on many factors (e.g., land use and species traits), but the amount of climate change that species experience in your region – known as climate change exposure – will certainly be important. For that reason, measuring and mapping climate change exposure is critical for predicting where climate change will have the biggest impacts. Yet, biologists have no agreed upon method to measure exposure and different methods can produce dramatically different results.

A Simple Measure of Exposure and its Limitations

Climate can be defined as a statistical description of weather (e.g., temperature, precipitation) over the course of a long time period, usually 30 years. Most often climate is reduced to the average value of a particular weather variable over a 30-year period of interest. Climate change is then measured as the difference between the averages in two time periods; say the predicted average between 2070-2099 minus the average between 1971-2000.

Projected changes in annual average temperature between 1971-2000 and 2070-2099

Projected changes in annual average temperature between 1971-2000 and 2070-2099.

For example, the map to the left shows projected exposure to changes in average annual temperature. This map suggests that species in the arctic will be exposed to the most temperature change while species in the southern hemisphere will experience the least change. However, there are many problems with this interpretation. Continue reading

Peer Review Week: Should we use double blind peer review? The evidence…

Non-blind Peer Review Monster

This week is Peer Review Week, the slightly more popular academic celebration than pier review week. Peer review is an essential part of scientific publication and is – like Churchill’s democracy – the worst system to do it. Except for all of the others. The reason it’s imperfect is mainly that it’s done by people, so there is a natural desire to try to improve it.

One suggestion for improvement is to us double blind reviews. At the moment most journals (including Methods in Ecology and Evolution) use single blind reviewing, where the author isn’t told the identity of the reviewers. The obvious question is whether double blind reviewing does actually improve reviews: does it reduce bias, or improve quality? There have been several studies in several disciplines which have looked at this and related questions. After having looked at them, my summary is that double blind reviewing is fairly popular, but makes little or no difference to the quality of the reviews, and reviewers can often identify the authors of the papers.

Peer review week: Encouraging collaborative peer review

Journal of Ecology Blog

Post from Managing Editor Emilie Aimé. Check out the methods.blog later in the week for some of the Methods in Ecology and Evolution Associate Editors’ perspective on collaborative peer review.

It’s Peer Review Week 2016 and the BES journals are celebrating with a series of blog posts on how much we value our reviewers.

Here at the BES we love Early Career Researchers. We give out grants to fund their research and training and development and we run and support several training and outreach programmes to help with the fantastic work they do. (Don’t forget to register for the Early Career Workshop at this year’s Annual meeting). Each of our journals also awards an annual prize for the best paper by an Early Career Researcher.

In this post though, we want to focus on Early Career Researchers as reviewers. The BES journals are very keen to give Early Career Researchers…
