A figure depicting the relative abundance of different prey items among two species of felid (e.g., monkey, small bird, agouti), derived from scat. The x axis is labeled "PoO (%)."

I would like to interrupt your doomscrolling for an important announcement: This figure from Ellen Dymit et al., 2025, depicts the proportion of vertebrate prey in felid scat, recorded as a Proportion of Occurrence (PoO). πŸ’©

a–d, Integrated non-dimensional pyrite content (a,c) and isotopic composition (b,d) exported from the sulfidic anoxic zone as functions of Ξ“0 and Da*. Panels a and b were calculated using the global averaged FeHR content, Ξ¨0 = 10, whereas panels c and d were calculating using Ξ¨0 = 1 as a low-iron endmember scenario. e, Example profiles showing predicted non-dimensional species contents/concentrations (OC, Ξ“; sulfate, Ξ£; sulfide, Ξ·; FeHR, Ξ¨; and pyrite, Ξ ) and isotopic compositions (d34S_SO4, d34S_S^2- and Ξ”pyrite) as functions of non-dimensional depth, ΞΆ, for three contrasting parameter-space conditions (marked as coloured circles in a–d). Stippled lines and lighter colours represent low Ξ¨0 whereas solid lines and darker colours represent high Ξ¨0 conditions. Vectors in panel a represent the expected change in global-average Ξ“0 and Da* for each bathymetric region when using the oxygen-penetration depth (vector base) vs the mixed-layer depth (vector tip) as model input. Boxes in panel b represent the 5th to 95th percentile range of Ξ“0 vs Da* extent observed for each bathymetric region in the modern ocean. Vectors in panel d represent global changes to various Earth-system evolution processes discussed in the main text. Sed. rate, sedimentation rate.

A big reason we have an oxygenated atmosphere is because there is a lot more pyrite burial than pyrite oxidation (which wasn't always the case). πŸ§ͺβš’οΈ

Good article, but the framing is wrong. There is not a dearth of interest in taxonomy. There is a scarcity of funding and positions, which is a deliberate choice by funding agencies and institutions. The youth love taxonomy! It's the olds that are failing to meet their passion!
