title: Data from: 120 Years of “Lemurology” - What has changed?

description: Lemurs, a highly diverse primate group endemic to Madagascar, have
 captivated the attention of researchers for nearly 120 years. Here, we
 conducted a literature review and a bibliometric analysis to provide an
 overview of how various aspects of “Lemurology”, or the scientific studies
 of lemurs, have changed over time. Focusing only on original scientific
 articles, we described the trends in the topics and taxa studied, the
 publication languages, the authorship, and study sites. We used two
 datasets: one from the Web of Science (WoS; 2,223 articles) and another
 from three Madagascar-focused journals (MFJ; 329 articles). The
 observation of lemurs in the wild is the oldest form of Lemurology,
 starting under the French colonization, and remains the main data source
 for articles in both datasets. Microcebus and Eulemur are the most studied
 genera in WoS and Propithecus and Eulemur in MFJ. At this time, no
 articles are written in Malagasy, but English and French are the main
 languages used in Lemurology. Although Malagasy scientists are still
 underrepresented at the international level, there is a recent shift
 toward an increased number of Malagasy scientists as first and last
 authors. We found no gender bias in WoS but MFJ exhibited noticeable male
 author dominance. Most Lemurology has been conducted at the Duke Lemur
 Center (USA), followed by Kirindy and Ranomafana forests in Madagascar.
 Lemurology thus shows different portraits at international and local
 levels, suggesting that unequal access to resources and opportunities may
 hinder the effective investigation and conservation of lemurs.
description: We searched for publications on Web of Science Core Collection
 (WoS) in September 2022. We used “LEMUR” as a keyword in “All fields”
 settings and did not set a time limit to review as much literature as
 possible. Our search was then refined to only include scientific articles,
 i.e., original peer-reviewed articles, excluding opinion pieces,
 conference and meeting proceedings, reviews, theses, books, and book
 chapters.  We downloaded and consulted all issues of
 the journal issues of <em>Lemur News</em>, <em>Malagasy
 Nature</em>, and <em>Madagascar Conservation and Development
 </em>in early 2023. We then built a dataset from these journals by
 reading the title and abstract of each scientific article and retaining
 only those about lemurs. This dataset comprised 329 articles published
 between 1993 and 2023.

We first categorized each article using Web of Science’s topics; then, we reclassified some of them to the most appropriate topic after we screened the abstract. We added a new category, “conservation human-lemur interactions”, for articles detailing any aspects of threats and pressures affecting lemurs, related to humans or not, and any aspects of conservation initiatives or projects leading to the preservation of lemurs. m)    **Extant Status**: Whether the species studied were extinct, extant, or both. n)     **#Species**: Number of species studied o)      **Species Focus **![](file:///C:/Users/veron/AppData/Local/Temp/msohtmlclip1/01/clip_image002.gif)**1 to 10**: Name of the species studied, up to 10. 2.    Variables unique to “WebOfScience” a)      **Author name**: Names of the authors b)     **MG **![](file:///C:/Users/veron/AppData/Local/Temp/msohtmlclip1/01/clip_image003.gif)**Last**: Whether the last author is a Malagasy or not c)      **Last Gender**: Gender of the last author based on information we found online and/or our acquaintance with the authors d)     **Field/Captivity**: Whether the research took place in a field or captive setting e)      **Site Name**: Name(s) of the field site(s) f)       **Latitude & Longitude**: Geographic coordinates of the sites. For each location in Madagascar, we identified and classified whether it is located within a Protected Area or its surroundings based on this information and using a map of Protected Areas across Madagascar (Map data from [https://protectedareas.mg/](https://protectedareas.mg/), accessed January 2024). We were unable to identify or correctly classify some sites because these were mentioned only by localities where the study was performed and/or campsite names without geographic coordinates. g)      **Collared**: Whether the studied individual lemurs were collared or not. h)     **Captured**: Whether the studied individual lemurs were captured or not. i)       **Last Affiliated **![](file:///C:/Users/veron/AppData/Local/Temp/msohtmlclip1/01/clip_image004.gif)**Country**: Country of the institutional affiliation of the last author. 3.    Variables unique to “MadagascarFocusedJournal” a)      **First **![](file:///C:/Users/veron/AppData/Local/Temp/msohtmlclip1/01/clip_image005.gif)**and Last **![](file:///C:/Users/veron/AppData/Local/Temp/msohtmlclip1/01/clip_image005.gif)**Author**: Names of the first and last authors. b)     **Volume**: Volume of the journal.
