📘 New #DynaTrait synthesis paper online, led by Ellen van Velzen: "Flexibility in Aquatic Food Web Interactions: Linking Scales and Approaches"

Read it here: link.springer.com/article/10.1

SpringerLinkFlexibility in Aquatic Food Web Interactions: Linking Scales and Approaches - EcosystemsTrophic interactions determine food web structure and influence biodiversity, community structure, ecosystem functioning, and food web responses to global change. These interactions are highly flexible, changing on temporal scales from diurnal to evolutionary times due to phenotypic plasticity, rapid evolution and species sorting. Small-scale experimental and theoretical studies of plankton interactions have demonstrated a high relevance of this flexibility for community dynamics and ecosystem processes in small, simplified communities. However, the extent to which this flexibility affects larger-scale systems, for example, global ocean dynamics and their responses to global change, is still poorly understood. Differences in methodology, focus and terminology between research disciplines limit our ability to project established effects of flexible trophic interactions onto larger spatial and temporal scales. We propose to bridge this gap with a general framework for upscaling knowledge from small-scale research to large-scale models. Building on examples from plankton communities, we use this framework to show how mechanisms demonstrated in small-scale studies can be linked to ecosystem functions relevant at large scales. We argue for incorporating flexibility in large-scale process-based models to improve their realism and predictive power, and discuss challenges and ways forward for achieving this. Finally, we suggest several concrete ways for upscaling small-scale studies to make their findings more relevant for large-scale research, to close existing knowledge gaps and to improve our understanding of how flexible trophic interactions affect dynamics and processes across scales.

J'ai pris au vol cette excellente série de @Hackingsocial sur les #traits de #personnalité et la notion-même de personnalité. Je vous la recommande chaudement pour mieux comprendre le rôle que peut jouer la #psychologiesociale dans nos approches des #réseauxsociaux et de ce qu'ils nous font.

Every so often I'm struck and surprised by how enduring some of my #traits are. #Subconscious patterns, right?

I wore the #purple #bunny ears to #school on the last day of my high school career, as they call it, when I was 17.

I wore the #pink #unicorn hat to my friends' farewell gathering circa 2014 when we were about 29.

On both occasions - and true to form - I, of course, took #photos of everyone else wearing the #silly props too.

arXiv.orgPersonality Traits in Large Language ModelsThe advent of large language models (LLMs) has revolutionized natural language processing, enabling the generation of coherent and contextually relevant text. As LLMs increasingly power conversational agents, the synthesized personality embedded in these models by virtue of their training on large amounts of human-generated data draws attention. Since personality is an important factor determining the effectiveness of communication, we present a comprehensive method for administering validated psychometric tests and quantifying, analyzing, and shaping personality traits exhibited in text generated from widely-used LLMs. We find that: 1) personality simulated in the outputs of some LLMs (under specific prompting configurations) is reliable and valid; 2) evidence of reliability and validity of LLM-simulated personality is stronger for larger and instruction fine-tuned models; and 3) personality in LLM outputs can be shaped along desired dimensions to mimic specific personality profiles. We also discuss potential applications and ethical implications of our measurement and shaping framework, especially regarding responsible use of LLMs.

That being said, I'm actually among the perverts that are fascinated by #templateMetaProgramming (even though I'm well aware of its limitations pertaining readability and maintainability). Which is why I took @tess venting as an opportunity to challenge myself into writing a workable approach to generic properties for C++ objects with a common interface:

If a post contains one or more typos, misspellings, &/or other grammatical errors, how does this impact the likelihood of you favoriting or boosting it, if at all? BONUS QUESTION: If you answered, "Decreases likelihood," are you, by chance, a professional writer or editor? ;)

You walk into a room & take a seat behind a large wooden desk. You hear the door lock click into place. In front of you is a single piece of paper & pen. A disembodied voice announces over a loudspeaker that you have 10 minutes to make use of the paper & that your results will determine whether you live or die. What will you do with the piece of paper?

#question#poll#polls

Are you #botanist or field #ecologist and interested to do your graduation thesis (#bachelor or #master) or an #internship in great scenery, on a hot topic and in cool climate (so far)? We look for field assistance in the #Dachstein #glacier forefields to study plant #traits and #succession this summer. More information here:

Please boost!

New lab paper alert:

Trait-based ecology is not yet predictive because the proliferation of new metrics muddied the waters.

Where others zig, we zag.

We propose testing old theories with new data.

We advocate for the ubiquitous power law and argue environmental variability in space and time fundamentally shapes trait variation.

Keep an eye out for Umaña led paper where we provide an empirical test.

#introduction: I'm a scientist at #CSIC, Spain, interested in the #ecology & #evolution of fire-prone #ecosystems, & more generally, in disturbance ecology. I aim to understanding the role of #fire and other #disturbances in shaping species, populations, #communities, #landscapes, #biomes, & the #biosphere.
