This asynchrony may influence signal design, as its effectiveness depends on adapting to predictable environmental conditions. Many lizard species scent\u2010mark territories by depositing waxy secretions made of protein\u2010lipid mixtures from specialized epidermal glands. These secretions, once left on a substrate, face environmental fluctuations, and their lifespan depends on the mixture's ability to tolerate such changes. Since some proteins in these secretions are enzymes, we hypothesize they may serve homeostatic functions, enabling the mixture to actively respond to external conditions. Accordingly, we can expect that (1) enzymes remain active in secretions; and (2) their abundance varies across an environmental gradient, tuning the homeostatic ability to the predictable external conditions. We tested these predictions using carbonic anhydrase (CA), an enzyme found in many lizard secretions that regulates pH by catalyzing the reaction between water and carbon dioxide. Protonography confirmed CA activity in proteins extracted from femoral gland secretions from eight\n                    <jats:italic>Podarcis<\/jats:italic>\n                    lizard species and\n                    <jats:italic>Psammodromus algirus<\/jats:italic>\n                    . We also analyzed CA abundance in males (\n                    <jats:italic>N<\/jats:italic>\n                    \u2009=\u200970) from 12\n                    <jats:italic>Ps. algirus<\/jats:italic>\n                    populations, and its correlation with the environmental gradient (geography, topography, climate).

Taken together, these findings suggest CA plays an enzymatic function that may help stabilize the internal chemical environment of secretions, potentially enhancing the scent\u2010mark's lifespan and effectiveness under varying environmental conditions.\n                  <\/jats:p>","DOI":"10.1002\/ece3.72023","type":"journal-article","created":{"date-parts":[[2025,8,22]],"date-time":"2025-08-22T00:59:37Z","timestamp":1755824377000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Secret of Secrets: Carbonic Anhydrase Concentration in Lizards' Femoral Gland Secretions Is Tuned to Environmental Conditions"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7144-3851","authenticated-orcid":false,"given":"Marco","family":"Mangiacotti","sequence":"first","affiliation":[{"name":"Department of Earth and Environmental Sciences University of Pavia, Universit\u00e0 degli Studi di Pavia  Pavia Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Fumagalli","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences University of Pavia, Universit\u00e0 degli Studi di Pavia  Pavia Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregorio","family":"Moreno\u2010Rueda","sequence":"additional","affiliation":[{"name":"Departamento de Zoolog\u00eda, Facultad de Ciencias Universidad de Granada  Granada Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5485-347X","authenticated-orcid":false,"given":"Francisco J.","family":"Zamora\u2010Camacho","sequence":"additional","affiliation":[{"name":"Departamento de Zoolog\u00eda, Facultad de Ciencias Universidad de Granada  Granada Spain"},{"name":"Departamento de Biolog\u00eda de Organismos y Sistemas Universidad de Oviedo  Oviedo Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Mart\u00ecn","sequence":"additional","affiliation":[{"name":"Departamento de Ecolog\u00eda Evolutiva Museo Nacional de Ciencias Naturales, CSIC  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6199-0074","authenticated-orcid":false,"given":"Roberto","family":"Sacchi","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences University of Pavia, Universit\u00e0 degli Studi di Pavia  Pavia Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,8,21]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.2174\/092986612801619507"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01021264"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1086\/285305"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5NP00029G"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.26496\/bjz.2019.31"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/bij.12414"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/azo.12160"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/1365-2435.12984"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/1365-2435.14687"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.geoderma.2015.07.006"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41597-023-02549-6"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1021\/pr101143m"},{"key":"e_1_2_9_14_1","volume-title":"Principles of Animal Communication","author":"Bradbury J.
