"I am a shark and fisheries scientists, author and educator. I am a marine biologist, an ecologist, a shark researcher, a female scientist. I am Colombian, I am Argentinian and I am American. A writer and an artist, I have my feet in the ground but my head in the clouds. I am a dreamer, an idealist and a surrealist. I am a conservationist, and an activist. I fight for the rights to learn and communicate science, for the rights to have clean air and water, for the rights to a healthy ocean and a healthy planet."

IOB has individual covers for each paper if the authors so choose.

This week, we are featuring some of our amazing covers from 2025.

We'll start with this one :

Tibial #Biomechanics and #Adaptive Response to Mechanical Stimuli in the Green #Iguana

T B Arlowe , et al
doi.org/10.1093/iob/...
"Mechanical loading models are used to study adaptive skeletal mechanobiology mechanisms. However, most studies have used mammal models, leaving a knowledge gap regarding how these mechanisms differ among vertebrate groups. To address this gap, we evaluated the in vivo bone strain environment of the left tibia in green iguanas during locomotion, axial compressive loading, and with finite element analysis. Our study involved examining male green iguanas (n = 7) over a range of speeds (0.45–1.34 m/s) and axial load magnitudes (–25 to –100 N) to determine peak strains. Bone strains were measured using single-element strain gauges and rosette strain gauges, surgically attached to the tibial anterior, posterior, and medial surfaces..."

Into the Spongy-Verse: Structural Differences between Leaf and #Flower Mesophyll
Jeroen D M Schreel et al
doi.org/10.1093/icb/...

"As the site of almost all terrestrial carbon fixation, the #mesophyll tissue is critical to leaf function..."

Cell and tissue trait diversity among (A–D) leaves and (E–G) flowers. (A) Average cross-sectional mesophyll porosity (θIAS; mm3 mm-3) for leaves, visualized by averaging across the depth of the microCT scan. Lighter colors indicate more cell material, and darker colors indicate more airspace. (B) 3D volume rendering of the intercellular airspace of leaves. Height (thickness) varies depending on the species. Numbers indicate the porosity (θIAS) of the tissue. (C) 3D volume rendering of one leaf palisade mesophyll cell from a leaf of each species. Numbers indicate the asphericity (⁠⁠) of the cell. (D) 3D volume rendering of one spongy mesophyll cell from a leaf of each species. Numbers indicate the asphericity (⁠⁠) of the cell. (E) 3D volume rendering of one spongy mesophyll cell from a flower of each species. Numbers indicate the asphericity (⁠⁠) of the cell. (F) 3D volume rendering of the intercellular airspace of flowers. Height (thickness) varies depending on the species. Numbers indicate the porosity (θIAS) of the tissue. (G) Average cross-sectional mesophyll porosity (θIAS; mm3 mm−3) for flowers, visualized by averaging across the depth of the microCT scan. Lighter colors indicate more cell material, and darker colors indicate more airspace. Note that in panels (A and G), the width and height are each 600 µm, and the tissue dimensions in panels (B and F) are 600 µm × 600 µm in the paradermal plane with variable height (thickness) depending on the sample. Cells displayed in panels (C–F) are visualized at different scales.

Classification of Odor-Derived #Electroantennograms with Machine Learning

fig 1 Experimental set-up, data processing, and Pipeline. (A) Experimental set-up. An excised M. sexta antenna is suspended between electrodes and exposed to volatile organic compounds (VOCs). The local field response of the entire antenna is recorded. (B) Signal normalization. Antennae responses were calibrated with ylang-ylang; responses to VOCs were normalized to the maximum and minimum of the ylang-ylang response. This technique resulted in reduced variance, indicated by the narrower shaded region in the normalized response plot, across experiments for each VOC tested. (C) Workflow. Data were collected, normalized, and passed through quality control where waves containing irrelevant frequencies were removed. A genetic algorithm (GA) was used to tune the parameters of a butterworth filter for signal filtering. The filtered time-series data was used in the SVM while principal components analysis (PCA) was used to produce dimensionally reduced components for the RF classifier.

Maxwell Girard is a Masters Student at the University of Helsinki in the Ecology and Evolutionary Biology Programme. He earned a Bachelor’s Degree in Biology with honors from Hamilton College (Clinton, NY) in 2024 where he studied amphibian reproduction in the herpetology research lab. His research focused on identifying trade offs within the traits involved in sexual selection. He is very excited to present his results, along with his co-authors, in IOB.

Fig. 1 Visualization of several of the traits we measured. (A) Methods shown for measuring the saturation and % coverage of the yellow throat. A color threshold in ImageJ includes all yellow coloration within the picture. This is used to calculate the percentage of belly and throat with yellow color. The circle on the throat is the area where hue and saturation were measured for each male. (B) Lithobates clamitans sperm cell, with head (includes midpiece) and flagellum. (C) Predictions of correlation matrices of pre- and postcopulatory traits under the PLFH and the trade-off hypothesis. The shape and color of the ellipses represent the strength of the correlation between the traits, with blue colors indicating positive correlations and red/orange colors indicating negative correlations.
