Growth is a critical aspect of life for all organisms, and understanding what can and cannot affect it allows us to predict what effect climate change may have on organisms like these zebrafish (Image Credit: Lynn Ketchum, CC BY-SA 2.0).
Warming increases the cost of growth in a model vertebrate (2019) Barneche et al., Functional Ecology, https://dx.doi.org/10.1111/1365-2435.13348
In ecology, how organisms grow is relevant across all levels of life. Growing faster than others can be selected for as an evolutionary advantage, if being bigger earlier means that you have a competitive advantage over other members of your species.
Because growth is so critical to life, it is important to understand what may affect the ability of an organism to grow. The only way an organism can grow is by converting energy it acquires from food to its own body mass, but outside influences, like temperature, can affect how efficient an organism is at this energy conversion. The authors of today’s paper wanted to investigate if this efficiency and the cost of growth itself changed across a range of projected temperatures.
Species like this red-crowned crane perform yearly migrations, but how do they weigh up the costs and benefits? (Image Credit: Alistair Rae, CC BY-SA 2.0)

Migratory birds make up a huge chunk of the world’s bird life, yet there are still a lot of gaps in our knowledge concerning why they migrate to the areas they do. There’s a variety of potential benefits to migration, from remaining within a comfortable temperature range or a preferred habitat, to gaining access to areas that have a surplus in resources, to escaping competition with resident species. However, migration also results in increased mortality due to the amount of energy it takes. This week’s study tried to analyse the drivers of migration, and what trade-offs were made between migration’s potential benefits and costs.
Miscommunication concerning ecosystems like the Great Barrier Reef can be extremely harmful to their future. I recently encountered a frustrating example of such misinformation. (Image Credit: Workfortravel, CC BY-SA 4.0)
Scientific communication is at the forefront of what we do here at Ecology for the Masses. We like to celebrate good examples of SciComm whenever we can. But every now and then it’s misused so overtly that you have to talk about it. So today I want to share a recent example of scientific communication that confused and worried me.
