Hey @Codeberg, I just found out about you and am looking forward to getting to know you better!

For now, I have the following question. I am a postdoctoral researcher and when I write a scientific manuscript, I usually upload code to GitHub under a Free Software License. This code mainly replicates the analyses of the study and is usually not developed further. Would it be appropriate to host such repositories on Codeberg or is it meant to only hold projects being actively developed? Thanks!

I would like to thank #EMBO and my coauthors for this very cool collaboration which allowed us to shed light on the origins of the amazing diversity in #torpor patterns of endotherms!

Stay tuned for more related work soon! 😉

A scenario of several independent gains of #hibernation is also consistent with:

a) the pattern of evolutionary transitions among #torpor states (post 6 above), and

b) the fact that variation among torpor-capable species is predominantly taxonomically structured (post 8 above).

Some have also suggested that #hibernation might have been instrumental to the survival of #mammals during the K-Pg boundary.

In contrast to these, we estimated a low probability for hibernation in ancestral mammals, with multiple gains of hibernation being more likely.

Q3️⃣: Was #hibernation present in early mammalian ancestors or did it evolve multiple times independently?

The argument for a single origin of hibernation in #mammals stems from its high degree of complexity, which would make multiple gains of hibernation difficult to occur.

Furthermore, torpor-capable species cover a wide range of physiological and ecological parameter space. The distribution of daily heterotherms and hibernators in this space is primarily taxonomically structured rather than environmentally structured.

Q2️⃣: Can we predict whether a given species is capable of torpor based on its physiological and ecological characteristics?

Features associated with torpor include low body mass, nocturnality, and a resource-poor environment. Nevertheless, such associations are quite weak.

Q1️⃣: Are daily torpor and #hibernation evolutionarily distinct #torpor types or parts of a continuum?

Our results strongly support the continuum hypothesis. That is, evolutionary transitions between no torpor and hibernation generally require an intermediate daily torpor step.

To address 3 key questions regarding #torpor #evolution, we compiled a #dataset of a) torpor capabilities and b) 21 ecophysiological variables for 1,338 species of #mammals and #birds.

We then analysed this dataset using a series of #phylogenetic comparative methods.

A wide range of #mammals can enter #torpor, including 🐻, 🦔, 🐭, 🦇, and 🐵.

Similarly, many clades of #birds include torpor-capable species. Yet, only a single bird species (the common poorwill; public domain picture by Louis Agassiz Fuertes) is known to hibernate.

#Torpor involves programmed and reversible decreases in metabolic rate, along with a drop in body temperature. Based on its duration, torpor in endotherms can be classified as daily torpor (<24 hours) or #hibernation (from days or weeks up to several months).

Numerous species of #mammals and #birds can respond to challenging periods (e.g., lack of food or water, extreme cold) through #torpor.
