“…This study is a step in improving our understanding of roadkill research in Panama. Anecdotal reports of emblematic species by the news media are common; yet the subject is receiving little attention by specialists (Pinto et al, 2020). Although some local biologists keep personal records of roadkills, data are mostly unavailable, and I am not aware of local organizations monitoring roadkills.…”

“…If the aim is to protect endangered species, which are often less frequent roadkills (Pinto et al, 2020) to implement speed bumps (Machado et al, 2015), increase road visibility (Reed & Woodard, 1981), or reduce speed limits (Hobday & Minstrell, 2008). In the case of this study road, I would recommend the installation of speed bumps in the hot spot around 4.0 km.…”

“…Further evaluation is needed to develop effective animal crossings either for multispecies or single species (Teixeira et al, 2013). If the aim is to protect endangered species, which are often less frequent roadkills (Pinto et al, 2020), then long‐term studies are required. Meanwhile, urgent strategies to mitigate roadkills could be to implement speed bumps (Machado et al, 2015), increase road visibility (Reed & Woodard, 1981), or reduce speed limits (Hobday & Minstrell, 2008).…”

“…One of the most obvious impacts of road networks is wildlife roadkills, which is one of the major sources of vertebrate mortality globally (Hill et al, 2019). However, for many countries, roadkill research is practically non-existing (Schwartz et al, 2020), such as the case of Central America (Pinto et al, 2020). Therefore, there is a substantial underestimation of the impacts of road networks on biodiversity in the region.Understanding the spatial and temporal patterns that influence mortality of wildlife provides the basis for mitigating wildlife threats in areas of ecological importance.…”

Road networks bring multiple negative effects for biological conservation, including habitat fragmentation, habitat loss, chemical, and noise pollution (Van der Ree et al., 2015). Moreover, roads may directly impact animals by causing changes in home ranges, movement, escape behavior, and possibly even their physiology (Trombulak & Frissell, 2000). One of the most obvious impacts of road networks is wildlife roadkills, which is one of the major sources of vertebrate mortality globally (Hill et al., 2019). However, for many countries, roadkill research is practically non-existing (Schwartz et al., 2020), such as the case of Central America (Pinto et al., 2020).

“…In particular, the development of mass tourism related to sea, sun, and sand amenities has been shown to represent an important threat to biodiversity (e.g., due to the development of resorts, the use of resources for buildings, transport, pollution by vehicle emissions, and litter), with important damages to coastal ecosystems (Davenport and Davenport 2006). Also, the presence of roads has a negative relationship with avian richness and abundance in different tropical regions, causing increased vehicle mortality, behavioral changes due to traffic noise, and increased hunting rates by humans that take advantage of these roads (Pinto et al 2020). Development of tourism can increase the rates of beach erosion and promote human activities in all forms, affecting habitat availability, productivity, and biodiversity (Yasué and Dearden 2006).…”

Birds of the Land of Swallows: contribution of the main ecosystems of Cozumel Island to its avian diversity

et al. 2021

Caribbean islands are important hotspots for endemic species, concentrating high biodiversity on exceptionally small areas. Cozumel Island is not an exception, yet little published information exists on its bird diversity. In this study, we assessed the contribution of each major ecosystem of Cozumel Island (i.e., tropical forest, mangrove, palm thicket, and urban setting) to the island's avian diversity. Avian richness was highest in tropical forests, followed by mangroves, palm thickets, and urban setting. Bird densities were highest in urban settings, followed by tropical forests, mangroves, and palm thickets. Species composition similarity among ecosystems was low, with the most dissimilar ecosystem being the urban setting. Interestingly, we recorded the highest number of unique species in mangroves, followed by tropical forests, urban settings, and palm thickets. Tropical forests and mangroves of Cozumel Island are the main ecosystems harboring high avian diversity, with tropical forests housing high avian densities and endemics and mangroves including the most unique species. As expected, the contribution of urban settings to the avian diversity of Cozumel Island is limited and includes some highly abundant invasive species, of which the Eurasian Collared-Dove could represent a major ecological threat. RÉSUMÉLes îles des Caraïbes sont d'importants points chauds pour les espèces endémiques, concentrant une biodiversité élevée dans des régions exceptionnellement petites. L'île de Cozumel ne fait pas exception, mais peu d'information existe sur sa diversité en oiseaux. Dans cette étude, nous avons évalué la contribution à la diversité aviaire de chacun des principaux écosystèmes de l'île de Cozumel (i.e., forêt tropicale, mangrove, fourré de palmiers, zone urbanisée). La richesse aviaire était plus élevée dans les forêts tropicales, suivies des mangroves, des fourrés de palmiers et des zones urbanisées. Les densités d'oiseaux étaient plus élevées dans les zones urbanisées, suivies des forêts tropicales, des mangroves et des fourrés de palmiers. La composition spécifique entre les écosystèmes avait une faible similarité; les écosystèmes urbanisés étant les plus dissimilaires. Nous avons enregistré le nombre le plus élevé d'espèces uniques dans les mangroves, suivies des forêts tropicales, des zones urbanisées et des fourrés de palmiers. Les forêts tropicales et les mangroves de l'île de Cozumel sont les principaux écosystèmes arborant une diversité aviaire élevée. Les forêts tropicales ont des densités aviaires élevées et abritent des espèces endémiques, tandis que les mangroves ont le plus d'espèces uniques. Tel qu'attendu, la contribution des zones urbaines à la diversité aviaire de l'île de Cozumel est limitée et inclut certaines espèces invasives très abondantes, parmi lesquelles la tourterelle turque, qui pourrait représenter une menace écologique majeure.

Ecuador has both high richness and high endemism, which are increasingly threatened by anthropic pressures, including roads. Research evaluating the effects of roads remains scarce, making it difficult to develop mitigation plans. Here, we present the first national assessment of wildlife mortality on roads that allow us to (1) estimate roadkill rates per species, (2) identify affected species and areas, and (3) reveal knowledge gaps. We bring together data from systematic surveys and citizen science efforts to present a dataset with 5010 wildlife roadkill records from 392 species, and we also provide 333 standardized corrected roadkill rates calculated on 242 species. Systematic surveys were reported by ten studies from five Ecuadorian provinces, revealing 242 species with corrected roadkill rates ranging from 0.03 to 171.72 ind./km/year. The highest rates were for the yellow warbler Setophaga petechia in Galapagos (171.72 ind./km/year), the cane toad Rhinella marina in Manabi (110.70 ind./km/year), and the Galapagos lava lizard Microlophus albemarlensis (47.17 ind./km/year). Citizen science and other nonsystematic monitoring provided 1705 roadkill records representing all 24 provinces in Ecuador and 262 identified species. The common opossum Didelphis marsupialis, the Andean white-eared opossum Didelphis pernigra, and the yellow warbler Setophaga petechia were more commonly reported (250, 104, and 81 individuals, respectively). Across all sources, we found 15 species listed as "Threatened" and six as "Data Deficient" by the IUCN. We recommend stronger research efforts in areas where the mortality of endemic or threatened species could be critical for populations, such as in Galapagos. This first country-wide assessment of wildlife mortality on Ecuadorian roads represents contributions from academia, members of the public, and government, underlining the value of wider engagement and collaboration. We hope these findings and the compiled dataset will guide sensible driving and sustainable planning of infrastructure in Ecuador and, ultimately, contribute to reduce wildlife mortality on roads.
