New bird paper led by the brilliant and talented Andrew Orkney! π£
We show that greater parental care is linked to greater evolutionary flexibility in how birds fly π¦
Plot of global benthic Ξ΄18O data for 0 β 5.3 Ma (Lisiecki & Raymo, 2005) with geomagnetic polarity subchrons displayed on the top x-axis and planktic foraminiferal primary biozones plotted on the bottom x-axis using the deeptime package.
A mammal phylogeny (Garland et al., 1992) plotted in the fan layout using the ggtree and deeptime packages. The greyscale concentric circles in the background indicate geological stages, whereas the linear colored timescale indicates geological epochs.
Early tetrapod occurrence data (Jones et al., 2023) plotted as a taxonomic/biostratigraphic range plot using the geom_points_range() function from the deeptime package.
A stratigraphic column of Cretaceous lithostratigraphic units from the San Juan Basin, USA. The deeptime package has been used to add pattern fill which indicate the primary lithologies of the units as reported by the Macrostrat API (Peters et al., 2018) via the rmacrostrat R package (Jones et al., 2024).

Thrilled to share our new paper out in BMC, part of my postdoc at @cornellvet.bsky.social! ππ
We found that larger mammals evolve more diverse morphologies, while smaller ones can explore many locomotor strategies without much change to their forelimbs.

I'm so excited to share my latest paper out now! How did the ancestors of mammals make the switch from sprawling to upright, taking over the world in the process? Spoiler alert; it's complicated! journals.plos.org/plosbiology/...

City toads vs country toads, who's the toughest? πΈ See our latest study, now published! π By comparing the morphology of common toads (Bufo bufo) across 4 different habitats, we found that toads donβt quite look the sameβ¦π

What a cool paper! π€© Using @inaturalist.bsky.social observations, Mayer et al. found that there are more melanistic snakes in colder regions than in warmer ones AND that melanistic snakes are more abundant with β¬οΈ avian predator density ππ¦ Have look at it here: doi.org/10.1111/jbi....

Source: reddit, user: denise1025 A very alien white mushroom strands surrounded by green underbrush and mossy trees. The mushroom is white and almost like a triangle on a stem. On its underside, there are "teeth"-like projections. On its top, it is flat white, except there are beads of red droplets like blood.
Day 21 of posting cool mushrooms every day:
The Bleeding Tooth fungus (Hydnellum peckii) has both teeth on its underside and "blood" on its top!
The "blood" is extracellular fluid, which is squeezed out when the fungus absorbs water, increasing pressure until the red fluid is squeezed out!
