Predator odor exposure with predator stress
From 2021 to 2025, 172 animal research papers mentioned predator stress and predator odor exposure in their title or abstract.
That is 8% fewer than the 187 papers of 2011 to 2015. Between the same two periods, the papers that mention predator stress and any of the 90 tests we count fell 10%. The 2021 to 2025 count may run low because of a dip in PubMed's indexing, explained under the year chart.

Papers that mention predator stress and predator odor exposure fell from 40 in 2021 to 28 in 2024, then rose to 35 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. We take a paper's species from PubMed's indexing when the indexing names one. Otherwise PubTator 3, NCBI's text-mining service, has to find a species in the title or abstract, or the paper is not counted. Papers that PubMed indexed under the subject heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025.
Which species the papers used
Each bar is a share of the 172 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.
Species
“Other animals” counts papers that use none of the species this chart names.
Tests mentioned alongside predator odor exposure
Each bar is one test, with how many of the 172 papers also mention it, and what share that is. Of these papers, 98 (57%) mention no other test.

Which papers count
A paper counts here when it is animal research and its title or abstract mentions predator stress and predator odor exposure.
A paper that mentions either only in its methods is missed, so the count runs low. The search terms are in the list of models and techniques and the test list. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.
More pairings
Every pairing of an animal model and a test with 30 or more papers from 2021 to 2025 has a page like this one.
Other tests with predator stress
The page on predator odor exposure counts all the papers that mention it, whatever they study. The page on predator stress ranks the tests mentioned with it.
