Googling trends in conservation biology



Googling Trends in Conservation Biology
EL PROULX, PHILIPPE MASSICOTTE, AND MARC P´ Centre de recherche sur les interactions bassins versants—´ emes aquatiques (RIVE) and Groupe de recherche interuni- versitaire en limnologie (GRIL), Universit´ eres, C.P. 500, Trois-Rivi ebec, G9A 5H7, Canada, Abstract: Web-crawling approaches, that is, automated programs data mining the internet to obtain in-
formation about a particular process, have recently been proposed for monitoring early signs of ecosystem
degradation or for establishing crop calendars. However, lack of a clear conceptual and methodological
framework has prevented the development of such approaches within the field of conservation biology.
Our objective was to illustrate how Google Trends, a freely accessible web-crawling engine, can be used to
track changes in timing of biological processes, spatial distribution of invasive species, and level of public
awareness about key conservation issues. Google Trends returns the number of internet searches that were
made for a keyword in a given region of the world over a defined period. Using data retrieved online for
13 countries, we exemplify how Google Trends can be used to study the timing of biological processes, such as
the seasonal recurrence of pollen release or mosquito outbreaks across a latitudinal gradient. We mapped the
spatial extent of results from Google Trends for 5 invasive species in the United States and found geographic
patterns in invasions that are consistent with their coarse-grained distribution at state levels. From 2004
through 2012, Google Trends showed that the level of public interest and awareness about conservation
issues related to ecosystem services, biodiversity, and climate change increased, decreased, and followed both
trends, respectively. Finally, to further the development of research approaches at the interface of conservation
biology, collective knowledge, and environmental management, we developed an algorithm that allows the
rapid retrieval of Google Trends data.

We used Google Trends, a freely accessible search Trends data and clinical cases of confirmed influenza in engine, to track changes in the temporal pattern (phenol- adults and no apparent time lags between the 2 sources of ogy) of biological processes and the spatial distribution of invasive species.

Early detection of invasive non-native species is therefore a fundamental component of pre- venting their establishment and spread. Because at their introduction populations are generally composed of few individuals, the initial stage of dispersion is a critical step toward the establishment of a non-native invasive species (Puth & Post 2005; Blackburn et al. 2011). However, eeks since 1 November governmental agencies often lack the resources to detect species introductions at their early stage of dispersion.
Moreover, in cases of established invasive species, a con- siderable amount of public and scientific resources areinvested annually to monitor the distribution of thesepopulations. Galaz et al. (2010) proposed combining web-crawling and expert-knowledge approaches for theearly detection of ecosystem change or degradation. In the context of our study, a first step in that direction is to determine whether web crawlers, such as Google Trends, can be used to map the spatial distribution of invasive species at the country level.
Google Trends spatially disaggregates the volume of returned search-term hits at the level of cities or regions eeks since 1 November within a country. To illustrate this feature and its potential to address the shortfalls of species detection and tracking,we mapped the distribution of search-term hits for 5 in-vasive species in the United States. We entered in Google Trends the following search-term queries: ash borer (Agrilus planipennis), Asian carp (Cyprinus carpio, Latitude (degree) Hypophthalmichthys molitrix, Hypophthalmichthys no-bilis, Mylopharyngodon piceus), fire ants (Solenopsis Figure 2.
