I recently worked with @amarques.bsky.social to make illustrations and finalize figures for three scientific publications focusing on the evolution and function of holocentric chromosomes

I can also help you illustrate your research with effective figures, graphical abstracts, and infographics 🧪🐡

A scientific illustration showing the life cycle of a plant Rhynchospora tenuis

Figure caption:
Life cycle of Rhynchospora tenuis (i.e. PECP-48 genotype) under achiasmatic meiosis.

Schematic representation of the R. tenuis life cycle (2n = 4). Both male and female meiosis occur without crossovers (achiasmatic inverted meiosis). Male gametogenesis is asymmetric, yielding a single functional sperm nucleus and non-Mendelian segregation. Fertilisation restores the diploid state with intact haplotypes, but only heterozygous seeds develop into viable embryos, ensuring faithful restoration of the highly heterozygous parental genome each generation.

Figure and caption from: bioRxiv 2026.01.17.700054; doi: https://doi.org/10.64898/2026.01.17.700054

Asked my Intro Plant Bio students to make Valentine's day plant meme using what they learned in class so far, and dang, it gives me SO MUCH joy seeing all the submissions.

text says "hold me like marchantia holds water", the pic is a lecture slide show marchantia archegoniophore holding water

text says "my love for you is as abundant as rubisco", with a protein structure of rubisco

text says "my love for you is liek apical meristems.. it keeps on growing", pic shows shoot and root apical meristem

text says "call me a xylem cell, because i would die for you"

#DarwinDay is celebrating how Darwin’s scientific work, perseverance and intellectual bravery made biology the scientific field we know today, united through the concept of #evolution 🧪🐡

In 2018, Ilja Van Braeckel created a font based on Charles Darwin's handwriting for #DarwinDay. It was based on 12,000 pictures of Darwin's original manuscripts!

Link rot happened, and the original files are missing. I have put it up again here: drive.google.com/file/d/14Kcn...

Happy Darwin Day!

Today we celebrate Darwin Day! 🎉
Today is not just about celebrating Darwin, but about how evolutionary biology helps us address today’s challenges.
Evolution is not only about the past. It’s a way of thinking for building more sustainable futures.
How are you marking Darwin Day?

Anticipate evolution to protect human health
Pathogens and cancer cells evolve rapidly.
Evolutionary biology helps us design health interventions, from antibiotics to cancer therapies, that anticipate evolutionary responses, slowing resistance instead of accelerating it.

Design food systems that work with evolution
Pests and pathogens adapt quickly to uniform crops and intensive practices.
Evolutionary thinking supports diversity-based and adaptive farming strategies that reduce evolutionary arms races and increase long-term food security.

Protect evolutionary potential in a changing world
Species and ecosystems respond to climate change through evolutionary and ecological processes that unfold over time.
Evolutionary biology highlights the importance of intraspecific biodiversity and helps identify which populations hold higher adaptive potential, and informs management and conservation plans to support resilience.

Reposted with alt text for people with screen readers - this is a welcome departure from how certain large organizations are handling revelations that high-profile members associated with and accepted money from Epstein and his organization, _AFTER 2008_ when he was convicted for soliciting a minor.

announcement from Dinocon:

DINOCON

We at DinoCon take the safety of our attendees, speakers, and staff very seriously. As a result of the release of half of the Epstein files, it has come to light that a select number of scientists, authors, and researchers relevant to the field of palaeontology allegedly engaged in correspondence with members of the Epstein organisation after the conviction of Jeffrey Epstein. We want to state that all respective individuals are banned from all of our events.

Additionally, we find it deplorable that some established palaeontological organisations are not taking firm action to protect their members in light of these allegations. As such, executive committee members from organisations that are not issuing public bans to these individuals are also banned from our events. We do not tolerate those who allow this behaviour to go unchallenged within our community.

Hello #PortfolioDay 🐡 I’m a scientific illustrator with a PhD in biology and research experience in ecology and evolution. My work includes infographics, illustrations, learning materials, and branding

I’m open to commissions and/or a full-time job in communications or educational design

A photo of a book open on a page showing illustrations related to colour theory. From "The Communicating Scientist" by Olle Bergman, Sarang Park, and Joanna Bagniewska, with illustrations by Dorota Paczesniak

A complex figure with a digital illustration and text boxes. Shows soil cross-section and a plant with above-ground and below-ground parts visible. The plant has four stalks: one with a bud, flower, and fruit, and one with brown and dried leaves that are falling off. This is to signal the main theme of the paper, i.e. phenology.

The text boxes are divided into two main categories: above-ground and below-ground and briefly explain the difference between these two environments in resource gradients, plant–soil functionality, and coupling to photosynthesis.

Morris, K., & Nair, R. (2025). Below the leaves: Integrating above- and below-ground phenology for earth-system predictability. Functional Ecology, 00, 1–19. https://doi.org/10.1111/1365-2435.70057

A photo of a leaflet open to show the first and the last page. This is an infographic for the Conservation Genetics Workshop titled „Types of genetic markers: What can they reveal?”
The first page features an illustration of the three levels of biodiversity: genes, species and ecosystems.
The last page has an info box about open and FAIR data.
