Black History Month is a UK-wide celebration that takes place every October, acknowledging and raising awareness of the contribution that Black African and Caribbean communities have made in Britain and across the globe. We are excited to promote and profile the work of Black ecologists and evolutionary biologists across the British Ecological Society blogs.

My name is Dr. Samniqueka Halsey, and I am a computational ecologist. I use modelling and statistics to answer questions about the way the world works. In particular, I try to inform management actions about disease emergence and conservation with my models. I have worked on projects regarding Lyme disease, Chronic Wasting Disease and a dune thistle that is threatened by habitat fragmentation. I realized that I genuinely wanted to become an ecologist starting in my junior year of college when I took an ecology course. This class exposed me to the joys of fieldwork, going outside, and collecting data. Combined with a few more courses such as aquatic ecology where I could go out to streams and lakes to collect water samples and then go back to the lab to analyze, it was fascinating. I was even able to be a field technician in Arizona, where I helped to trap prairie dogs to collect blood and ectoparasites to test for the plague.

Girls and women make up half of the world’s population and therefore contribute to half of the talent and potential on our planet. Despite representing 3.9 billion people, women are yet to receive the equal rights and opportunities which are currently provided to men. As of 2014, 143 out of 195 countries guarantee equality of women and men in their constitutions, but in practice this is rarely achieved for women.

International Women’s Day is a global day celebrating the social, economic, cultural and political achievements of women. The day also marks a call to action for accelerating women’s equality. This year, the theme is #EachforEqual, highlighting that an equal world is an enabled world. One of the key missions for this theme is ‘forging inclusive workplaces so women can thrive’. This is particularly important for retaining women in STEM fields. Ultimately this mission needs to start in schools, because girls as young as 10 are reported to feel ‘out of place‘ in STEM subjects.

This blog post features some of the initiatives aiming to retain girls in STEM fields and shines a light on how far we have to go before girls and women are treated and represented equally in STEM.

Editor Recommendation: A Practical Guide to Structured Expert Elicitation Using the IDEA Protocol

Today is International Women’s Day to mark the occasion I have the privilege of recommending, ‘A practical guide to structured expert elicitation using the IDEA protocol‘ by Victoria Hemming et al. The IDEA behind the IDEA protocol – ‘Investigate’, ‘Discuss’, ‘Estimate’ and ‘Aggregate’ – is to provide a framework for Structured Expert Elicitation.

As a quantitative ecologist, I sometimes attempt to model species’ abundance and distribution changes in response to environmental change. Often these are species that, for one reason or another, we know a lot about. They may be high profile species of conservation concern, or have some economic or cultural importance. Some are simply model species that many people have studied because they’re easy to study because many people have studied them. Just as often though, we’re missing crucial data on one or more parameters. Frustratingly we don’t always have the time or resources to collect the new ecological or biological data required.

Bias, Role Models and Women in STEM

As the newest Senior Editor of Methods in Ecology and Evolution – and someone who happens to have two X chromosomes – I’ve been asked to write a blog post to mark the International Day of Women and Girls in Science.

After being a postdoc for almost ten years, I landed a permanent academic job in the city I wanted to live and raise my daughter in. I have great colleagues and I love my job as a researcher and teacher. I feel incredibly lucky: I am a female scientist and I “made it”.

When I showed the previous paragraph to a close friend and fellow “scientist who made it” he reminded me that a male colleague could easily have written exactly the same thing, only replacing “female” with “male”. Although I agree with his observation, I was deeply frustrated by what could be implied by his response.

His response illustrates a problem: some people may think it’s “all fine” now or that the issue of gender inequality has been solved. They cite the numerous measures in place at different levels to help women enter STEM fields and to ensure female scientists get an equal chance at staying in the game. It might be close to “all fine” in Scandinavia – a region known for long periods of parental leave and ingrained culture to put children and families above work – but it’s not all chocolate mousse and cheesecake everywhere in the world.

Evelyn Chrystalla ‘E.C.’ Pielou (February 20, 1924 – July 16, 2016) – a towering figure in ecology – was a key pioneer in the incorporation of statistical rigor into biogeography and ecology. She devised many important statistical hypotheses tests for spatial arrangements and patterns ranging in scale from individual plants in a field through to elevational zonation of vegetation to ranges of groups of species distributed over regional through to continental-scale ranges. Her research has provided the impetus for biogeographical analyses for generations.

She published ten books, including several long after her formal retirement in 1988. Her book Biogeography (1979) is a masterpiece. It covers historical biogeography (including inferences from cladograms, which were just beginning to be a hot topic at that time) and ecological biogeography with keen insight and treats topics like long-distance dispersal (that had largely been the subject of just-so stories) with her characteristic statistical rigor. Her books on mathematical ecology have a strong emphasis on models of spatial pattern and ways to estimate biodiversity, and her methods – including the famous Pielou‘s evenness index – are still widely used.

Movement ecology is a cross-disciplinary field. Its main aim is to quantitatively describe and understand how movement relates to individual and population-level processes for resource acquisition and, ultimately, survival. Today the study of movement ecology hinges on two 21st century advances:

  1. Animal-borne devices/tags (biologging science, Hooker et al., 2007) and/or remote sensing technology to quantify movement and collect data from remote or otherwise challenging environments
  2. Computational power sufficient to manipulate, process and analyse substantial volumes of data

Although datasets often involve small numbers of individuals, each individual can have thousands – sometimes even millions – of data points associated with it. Study species have tended to be large birds and mammals, due to the ease of tag attachment. However, the trend for miniaturisation of tags and the development of remote detection technologies (such as radar, e.g. Capaldi et al., 2000), have allowed researchers to track and study ever smaller animals.

Breaking academia’s glass ceiling

Breaking academia’s glass ceiling

Women in academia are special. This isn’t because of their abundance and diversity (or lack of it in some circles) but rather because of the challenges faced by women. As an early career woman researcher, I have had the privilege of knowing and learning from some incredibly inspirational women scientists. In this post – peppered with the lyrics of Joan Baez – we will meet three of these exceptional scientists working in three different realms (terrestrial, estuarine and marine). I hope that their strengths will be as inspirational to others – as they have been to me – and that in the years to come, we, as women, shall overcome the glass cliffs and glass ceilings of academia.

We’ll Walk Hand in Hand, Some Day #Equality

In the terrestrial realm of tropical forests, researchers often have to work with government officials (for instance, the forest department). Challenges of gender equality can be particularly stark in these workplaces. A key challenge for women in such a setting is not being considered a professional. Female researchers are far too often underestimated: lecturers assumed to be trainees, post-doctoral researchers mistaken for students. Continue reading →

Whether you are a laboratory or a field scientist, you have to be willing to get your hands dirty from time to time for the good of science. Sarah and I took that literally and spent a large part of our respective PhD projects handling faeces of free-ranging spotted hyenas from the Serengeti National Park and the Ngorongoro Crater, Tanzania.

Though faeces often are underrated, they are highly valuable material to work with because they conceal the most secret details about an animal’s social and sexual life. But having the privilege of holding a still-steaming poop is something you have to earn! Continue reading →

International Women’s Day: Advice for Women Starting a Career in STEM

Posted on by

So far this week we’ve heard why some of our female Editors chose to pursue a career in science, what the problems the push for gender equality faces in STEM fields  and where things have been improved in recent years. To close International Women’s Day our posts from the Editors we asked: What advice would you give to female students or Early Career Researchers looking to make a career in academia?

SusanJohnston2Susan Johnston: Mentorship schemes: there are many benefits from being able to have transparent, open and reciprocal discussion on career development, as well as the unwritten rules and experiences of academia. In smaller or less diverse departments, supervisors could encourage their female students to contact potential mentors (male or female) from other institutions. A quick Skype conversation every few months can benefit both the mentee and the mentor.

Carolyn KurleCarolyn Kurle: Don’t be daunted by the idea of how challenging a position in academia might be and don’t remove yourself from the path of academia just because you might be afraid of the potential demands. More and more support exists for mixing successful academic lives with also being a present and fulfilled parent and having a full life outside of research. And the more we expect that to be the case, the more it will exist as reality. Continue reading →

Getting Every Last Bit Out of Dives: Data Abstraction On-board Telemetry Tags

Animal Telemetry for Air-breathing Divers

Nowadays animal telemetry tags for air-breathing divers come in all shapes and sizes. In four short decades tags for diving animals have gone from prototypes like the one built by Jerry Kooyman for deployment on Weddell seals – which consisted of a kitchen timer and a roll of graph paper – to a multitude of sophisticated electronic devices, fit for just about any animal or purpose you can think of.

All this progress has meant we can collect more information than ever before and do so remotely. Nevertheless, the lives of most divers remain a well-kept secret. For tags that transmit what they collect (as opposed to those that store data until they’re retrieved), the transmission stage is usually the bottleneck. This has driven the development of energy and time efficient software and data processing.

For a tag like the conductivity-temperature-depth Satellite Relay Data Logger (CTD-SRDL) built by the Sea Mammal Research Unit Instrumentation Group at the University of St Andrews – which was designed to spend months at sea – the problem boils down to one thing. Data are collected at a high resolution on-board the tag amounting to 100kB daily, but only 1kB of this information (at best) can be transmitted to the ground station. Therefore in preparation for transmission, the data need to be chosen carefully, compacted and fitted into several satellite messages of fixed size to ensure that enough useful information is received. Each satellite message can hold up to 248bits of information. To give an idea of how limiting this is, consider that this sentence would (without compaction) take up 896bits! Continue reading →
