Abstract

© 2018 Nederlandse Ornithologische Unie.All rights reserved. Monitoring programmes are needed to assess the conservation status of species and to quantify the effectiveness of conservation effort. Rare species are usually poorly studied due to difficulties in monitoring. We evaluated the use of autonomous recording units (ARUs) coupled with automated song recognition for monitoring the presence of Dupont's Lark Chersophilus duponti, a rare and patchily distributed species. We surveyed 49 potential habitat patches for the species in central Spain never censused before, from May to June 2017. In each habitat patch we deployed an ARU that recorded one continuous hour during two consecutive nights. In addition, we also performed line transect censuses in 22 out of the 49 potential habitat patches, to evaluate the efficacy of ARUs. Audio analyses revealed the existence of eight previously unrecorded Dupont's Lark populations. Line transect censuses always confirmed the presence or absence of the species in agreement with audio analysis results. ARUs required 44 fewer working days than human-based surveys for monitoring the presence of Dupont's Larks in potential habitat patches. Our results suggest that the use of ARUs coupled with automated song recognition can provide an effective alternative to human-based surveys for monitoring the presence of bird species in large-scale surveys. We conclude that a combined methodology using ARUs and field censuses, in order to estimate densities or spatial patterns, may be considered the most effective method for monitoring large numbers of potential occupancy sites.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal ARDEA due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2018, it was in position 12/28, thus managing to position itself as a Q2 (Segundo Cuartil), in the category Ornithology. Notably, the journal is positioned en el Cuartil Q2 para la agencia Scopus (SJR) en la categoría Animal Science and Zoology.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 3.76. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 2.32 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 3.87 (source consulted: Dimensions Jul 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-07-04, the following number of citations:

  • WoS: 24
  • Scopus: 26
  • Google Scholar: 33

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-07-04:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 50.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 50 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 0.5.
  • The number of mentions on the social network Facebook: 1 (Altmetric).
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).
