#30DayChartChallenge Día 16: Negative Relationship FOUND!

¡Lo conseguimos! Tras ajustar por masa corporal, la relación entre Tasa Metabólica Específica (W/kg) y Longevidad Máxima (años) en ~530 especies animales (AnAge DB, outliers quitados) SÍ es negativa (Pearson ρ ≈ -0.42, p < 2.2e-16). #RelationshipsWeek #Animals

El gráfico log-log muestra la tendencia: mayor intensidad metabólica por kilo se asocia con vidas más cortas. ¡Apoya la idea del "ritmo de vida"! Colores por Clase Taxonómica.

Un recordatorio de la importancia de normalizar variables y limpiar datos para ver la señal correcta. ¡Ciencia en acción!

#30DayChartChallenge Día 13: Clusters Animales! Explorando la relación Masa Corporal vs Longevidad Máxima. #RelationshipsWeek

Usando un dataset de Kaggle (+170 especies, ¡gracias S. Banerjee!) y tras una divertida limpieza de datos con rangos/unidades mixtas , este scatter plot log-log revela patrones.

Coloreamos por Dieta: Carnívoro(verde) Herbívoro(ocre) Omnívoro(azul).
Se ve la tendencia general (más grande = más longevo), pero los clústeres por dieta sugieren distintas **estrategias de historia de vida**. ¿Cómo gestionan su energía y longevidad según lo que comen?

¡Una visualización para explorar la alometría y la diversidad ecológica!

Exciting new paper here assessing ages for #puberty onset and #menarche among #UpperPalaeolithic #huntergatherers (from Russia, Czechia, Italy).

'Our results revealed that while puberty had begun by 13.5 years of age for the majority of individuals, there was a lot of variability, with the adolescents from Arene Candide (AC1 and AC16), both aged around 16 years when they died, taking several years longer to progress through puberty than their peers. Assessing the age of menarche was challenging due to the paucity of female adolescents, but based on the available evidence, it appears to have occurred between 16 and 17 years of age. For some, full adulthood had been achieved by 17–22 years, similar to the patterns seen in modern wealthy countries and in advance of historic populations living in urbanized environments.'

loss of old wise animals -- devastating to their social systems

'Earth's old animals are in decline. Despite this, emerging research is revealing the vital contributions of older individuals to cultural transmission, population dynamics, and ecosystem processes and services. Often the largest and most experienced, old individuals are most valued by humans and make important contributions to reproduction, information acquisition and cultural transmission, trophic dynamics, and resistance and resilience to natural and anthropogenic disturbance.These observations contrast with the senescence-focused paradigm of old age that has dominated the literature for over a century yet are consistent with findings from behavioral ecology and life-history theory. Here, we review why the global loss of old individuals can be particularly detrimental to long-lived animals with indeterminate growth, increasing reproductive output with age, and those dependent on migration, sociality and cultural transmission for survival.'

#IntroductionPost #aboutme #lifehistory

TL;DR: read my profile bio jeez

"Gifted child" turned into terminally online sonic fan, who eventually jumped ship to furry fandom for... uh... many reasons. At least they taught me to read and somewhat speak English!

Always liked being able to customize games and experiences, from age 10 I started by replacing sprites in GBA games and modifying Gamemaker games. This turned into an affinity for tech and programming, as I saw it as sort of our world's version of magic (Write a spell and your magic box will do it kinda thing)

Throughout highschool I got to learn how to work different workshop tools for carpentry, as well as more coding-related stuff like coding in C for arduinos and building simple mobile apps for our "science-fair".

Towards the end of highschool, the oculus dk1 was announced, and I got stupidly hyped about the idea of VR. So much so in fact that I ended up building my own google cardboard before google cardboard! It was terrible and laggy, but a phone, some wood and a wiimote/airmouse was enough to fool VR demos into working! Thus began a mixed hobby-career of art and tech.

I was drawing a lot in class, and by the time I started uni I had a drawing tablet and some decent enough skills to see all that I could learn. When I got hooked into VR, that energy went into 3D modelling: I saw that JanusVR (cool 3d web browser prototype!) supported custom playermodels and a week flew by me just learning to stitch together pieces of models downloaded from the internet. I had my first furry 3d avatar, and it was gloriously crunchy, but it was mine.

During uni I studied what you would expect a CS major to learn, and got into making little ESP projects + a bunch of scripting for setting up machines to be servers because docker + winXP is a no go lol. I enjoyed my time there, but it always felt like I was being shoved into Web Development.

And that's exactly what I've worked as for 4 years, a fullstack web dev. It's been a wild ride, but I still continued to enjoy my artistic hobbies, and ended up even making commissions for VRChat avatars! I keep remaking my own 3D model like a fursuiter keeps improving their main suit (or making more), so I'm always changing a little bit. Very happy with my current iteration.

I have a nice long story about trying to flee my country and working in Japan, but that would make this post way longer than it already is, so just know that I've had to look for a job back home again for 6 months, and at the time of writing finally got it! Excited for the future!

I like seeing old webcore designs for themes, apps, sites or even just frontends for modern stuff, so please do share your custom MSN-lookalike discord clients and your win98-looking linux installs! It's a breath of fresh air in the sea of bland corporate designs.

Hope this wasn't too long for you, and feel free to reply to this message with questions if I got you curious about my life or hobbies!

Can't wait to start stream ecology by taking my students into the snow to see the #insects of winter. There are too many fair weather #ecologists who don't visit #rivers in suboptimal conditions. Unfortunately that means missing a lot of critical #LifeHistory

I've been here a few weeks but have yet to make an #introduction. Here goes:

I'm Owen, an Associate Professor at the University of Southern Denmark. My research focuses on #LifeHistory evolution, #PopulationBiology, and #senescence. I teach #Rstats, evolution, and population biology.

I'm one of the folk behind the COMPADRE/COMADRE matrix population databases. I'm also running a #NestBoxProject on campus.

I'm an #immigrant to Denmark and a dad of two boys and I'm currently confused by Pokemon.
