The Kids Are Not OK: Causes of Infanticide in Female Mammals

The Crux

The practice of male mammals killing their rival’s cubs has been well-documented by wildlife biologists. The image of a male lion striding away from a pride with a dead cub in his mouth is quite haunting (spare a though for Scar’s kids when Simba takes over again). But infanticide by female mammals has received less attention.

Whilst males generally only kill young to ensure they have more access to mates, the motivations behind infanticide in females are more complex. It ultimately comes down to resource competition, but the resources themselves are myriad – milk, availability of space, care from more than one ‘parental’ figure (allocare), and social status. These four resources make up the competing hypotheses as to why females commit infanticide. This week’s researchers wanted to know what factors of a species biology increased the likelihood of a mother to kill an infant of the same species.

Plastic Fanatics

It is hard to deny that plastics are having a moment – you open Facebook to find videos of turtles floating among plastic bags, Instagram to find every company is proudly getting rid of plastic straws, the news to find out the latest on the Great Pacific garbage patch. Plastics are what colony collapse disorder (aka. where are the bees going?) was a few years ago: the new environmental issue that everyone is talking about.

Now, plastics are certainly an irrefutable problem. We obviously have an unhealthy dependency on plastics that are found in our clothing, food, soaps, and homes. However, there is a question among conservationists and scientists over whether or not it is a good thing that the public conscious seems to become obsessed with a single issue, while others outside the limelight seem to fall away (similar to how in the USA people seem to have forgotten that Flint is STILL without clean water). I want to discuss how the new media landscape propels environmental fads, the good they can do, and the possible problems.

Interdisciplinarity in the Classroom: The Experts in Teamwork Approach

The concept of interdisciplinarity (essentially, scientists from different backgrounds working together to solve scientific questions) has played a major role in the development of ecology, and science in general, in the last few decades. As odd as it sounds, working across disciplines, even those as closely related as population and behavioural ecology, wasn’t a regular occurrence. Papers with one author were fairly commonplace.

Prue Addison: Integrating Sustainability Into Business

With the environmental movement having expanded so quickly over recent decades, it makes sense that many large corporations have started to incorporate sustainability and the environment into their business plans. But what are these business actions actually achieving? And who bridges the gap between the corporate world and the field of ecology?

At the recent Norwegian Ecological Society Conference, Tanja Petersen and I sat down with Doctor Prue Addison from the University of Oxford. Prue works with multinational corporations to aid them in integrating biodiversity considerations into their business operations. We asked her about the difference between business and academia, how she’s managed to transition between the two, and advice for others looking to make the same leap.

Eva Plaganyi: Understanding the Human Side of Ecology

At the end of the day, the aim of an ecologist is to generate a better understanding of the natural world around us. But that can amount to nothing if that understanding isn’t translated to the people who interact directly with the aspects of the natural world that we research. So whilst understanding an ecosystem should be our main priority, understanding the people who interact with an ecosystem is integral to making a difference.

This is where social sciences like anthropology can help. At the ASFB 2018 Conference, I spoke to plenary speaker CSIRO’s Dr. Éva Plagányi, who works on maintaining the sustainability of marine life. Éva’s work includes interaction with everyone from corporate businessmen to traditional fishers, and integrating social anthropology into her work has yielded great results. I spoke to Éva on the importance of incorporating social science into ecology.

Jarod Lyon: Science Communication at the Coalface

Jarod Lyon believes that people still want to hear science from experts, but that our perception of what makes an expert has changed

The advent of social media changed many things about the world, but if there’s one big change that’s become really quite evident in the last two years, it’s how we get our information. This has influenced ecology dramatically over the last decade, with a great deal of scientists now present on social media. But are we adapting fast enough, and in the right way?

At the Australian Society of Fish Biology’s Annual Conference last week, Jarod Lyon, who manages the Applied Aquatic Ecology Section at Australia’s Arthur Rylah Institute, gave a talk about applied science in the ‘fake news’ era. I took the opportunity to sit down and quiz Jarod as to how we need to approach public communication in the era of social media.

Fortune Favors the Bold Spider

Leadership can play an important role of a population dynamics, but is it the strength of the leaders or the willingness of the followers that has more influence?

Selection for Collective Aggressiveness Favors Social Susceptibility in Social Spiders (2018) Pruitt et al., Current Biology, doi: 10.1016/j.cub.2017.11.038.

The Crux

Socially-influential leaders can have a large effect on the actions of any group. Think of that one person in your life that everyone looks to when it’s time to make a decision; whether it’s something trivial like where to go for dinner, or something more important like whether or not to take that job on the other side of the country, these individuals make a large impact in their social circles. This can also be seen in the natural world, like the alpha of a wolf pack, or the matriarchs of an elephant troop or an orca pod. These focal individuals greatly influence the actions and success of their groups.

In order to determine not only how important these influential individuals are, but also how much the “social susceptibility” of the followers matters, the researchers in this paper used a species of social spider in two different habitat types. By using both arid and wet environments and analyzing both sides of the influence coin, this study was able to accurately determine the importance of both influencing and being influenced in different ecosystems.
