Para, piensa, y ten cuidado con las configuraciones por defecto

Pasaste meses laboriosamente colectando datos de artículos científicos acerca de tu pregunta favorita, tienes decenas de artículos perfectamente organizados en una base de datos, ya encontraste el programa o código para analizar los datos, y entonces imaginas como tu publicación va a ser la más citada en tu campo de investigación mientras haces unos gráficos lindísimos. Si esto te suena familiar, seguramente has hecho un meta-análisis. Un meta-análisis usa modelos estadísticos para combinar datos de distintas publicaciones para responder a una pregunta específica.

Lo que quizás no te diste cuenta mientras navegabas los pasos del meta-análisis, es que pequeñas decisiones (a veces pareciendo de muy poca importancia) pueden tener grandes efectos en los resultados. Si quieres saber más acerca de una de estas decisiones en particular… ¡sigue leyendo!

Stop, think, and beware of default options

You spent months carefully collecting data from articles addressing your favorite scientific question, you have dozens of articles neatly arranged on a spreadsheet, you found software or code to analyze the data, and then daydream about how your publication will be the most cited in your field while making cool plots. If that sounds familiar, you have probably done a meta-analysis. Meta-analysis uses statistical models to combine data from different publications to answer a specific question.

What you may not have realized when going down the meta-analysis rabbit hole, is that small, seemingly inconsequential, choices can greatly affect your results. If you want to know about one of them lurking behind the scenes… read on!

Happy 10th Anniversary to us!

This year is our 10th Anniversary! To celebrate, we’ve made a timeline of highlights from the past decade, from the first paper ever submitted, to a top-cited article with 3,295 citations.

We’d like to give a big thanks our dedicated editors, plus all the authors and reviewers who are developing the fields of ecology and evolution with groundbreaking new methods. Here’s to 10 more years!

MInOSSE: all you need to reconstruct past species geographic range is in the fossil record!

Post provided by Francesco Carotenuto

A very important ecological feature of a species is its geographic range, which can be described by its size, position and shape. Studying the geographic range can be useful to understand the ecological needs of a species and, thereby, to plan conservation strategies. In ecological studies, mathematical models are the new standard to reconstruct the distribution of living species on Earth because of their accuracy in predicting a species presence or absence at unsampled locations. These methods are able to reconstruct the climatic niche of a species and to project it onto a geographic domain in order to predict the species’ spatial distribution. To do this, besides the occurrences of a species, the models necessarily require the spatial maps of environmental variables, like temperature and precipitation, for all the study area.

Methodology matters for comparing coarse wood and bark decay rates across tree species

A decaying Douglas fir log

This picture shows a decomposing log of Douglas fir, Pseudotsuga menziesii (Mirb.) Franco, in Schovenhorst, The Netherlands, which is one of the deadwood incubation sites of the LOGLIFE “tree cemetery” project. 25 angiosperm and gymnosperm species covering a diverse range of functional traits were selected and incubated in the “common garden experiment”. This project was founded in 2012, aiming to disentangle the effects of different species’ wood traits and site-related environmental drivers on decomposition dynamics of wood, and its associated diversity of microbial and invertebrate communities.

In the Spotlight: Wife-Wife Ecologists

Post provided by Chloe and Jessica Robinson

 

For LGBTQ+ Pride month, we are inviting LGBTQ+-identifying ecologists and evolutionary biologists to share their experiences of being LGBTQ+ in their field and present their thoughts on how the STEM can improve lives for LGBTQ+ individuals. For this post, wife-wife team Chloe and Jessica Robinson from Centre for Biodiversity Genomics at the University of Guelph, share their experiences of being married ecologists in STEM.

Jessica (left) and Chloe Robinson (right) met whilst studying at Swansea University.

C: “Find a job you love, and you’ll never have to work a day in your life” is a quote many of us are familiar with and it is something I have always strived to achieve. In my experience, by adding “Find a job you love & someone who shares your passion and you’ll never have to work a day in your life” to this quote gives the recipe for a happy marriage also. That ‘someone’ for me is my wife, Jessica.

In the Spotlight: LGBTQ+ Ecologists and Evolutionary Biologists

Post provided by Vishwadeep Mane

For Pride Month, we are inviting LGBTQ+-identifying ecologists and evolutionary biologists to share their experiences of being LGBTQ+ in their field and present their thoughts on how the STEM can improve lives for LGBTQ+ individuals. First up we have Vishwadeep Mane, a first-year microbiology PhD student at the Indian Institute of Science (IISc), Bengaluru.

Vishwadeep Mane shares his experience of being LGBTQ+ in microbiology.

Hello Everyone! Namaste! The world today is on the brink of a whole new era, an era of rethinking better. The Pandemic portrayed the necessity of sustainable reforms that are imperative for adapting to newer situations. Nevertheless, it brought the whole world together, gave us a reason to fight, love and respect. This month marks the ‘rebellion’ that gave voices to many unheard stories and changed the course of life of many individuals. To a greater extent, it helped in making this world a place for all with equality and respect. This ‘rebellion’ gave the moment of ‘Pride’ to possibly everyone unique in their own way. Happy Pride Month to all of you!

The tripod frame: mooring acoustic receivers on the seabed

Post provided by Jolien Goossens

Jolien Goossens tells us about the challenges of installing acoustic receivers on the seabed and the tripod they designed to overcome them.

sea

Installing scientific instruments in the marine environment comes with many challenges. Equipment has to withstand the physical forces of tides, currents and storms. Researchers have to take into account the effects of biofouling, corrosion and human activities. Even access to the study site can pose its difficulties, as diving is limited by depth and weather conditions. Practical deployment mechanisms are therefore needed to sustain consistent data flows.

Acoustic telemetry enables the observation of animal movements in aquatic environments. Individual animals are fitted with a transmitter, relaying a signal that can be picked up by acoustic receivers. To facilitate a convenient installation of these instruments, we developed and tested a new design, mounting a receiver with an acoustic release on a tripod frame. This frame enables the recovery of all equipment and better yet, improves the quality of the data.
