“…Previous studies have accounted for the sampling bias in opportunistically collected data through a variety of ways, such as changes in detection across time (Kéry & Schmid, 2004), observer effort (Mair & Ruete, 2016), spatial correlation of observations (Clement, Hines, Nichols, Pardieck, & Ziolkowski, 2016), habitat factors (Paolino et al., 2018) and spatial estimates of human presence. However, the spatial metrics used in these studies are static, rarely updated and often do not reflect temporal trends such as seasonal traffic volumes.…”

The integration of citizen scientists into ecological research is transforming how, where, and when data are collected, and expanding the potential scales of ecological studies. Citizen‐science projects can provide numerous benefits for participants while educating and connecting professionals with lay audiences, potentially increasing the acceptance of conservation and management actions. However, for all the benefits, collection of citizen‐science data is often biased towards areas that are easily accessible (e.g. developments and roadways), and thus data are usually affected by issues typical of opportunistic surveys (e.g. uneven sampling effort). These areas are usually illuminated by artificial light at night (ALAN), a dynamic sensory stimulus that alters the perceptual world for both humans and wildlife. Our goal was to test whether satellite‐based measures of ALAN could improve our understanding of the detection process of citizen‐scientist‐reported sightings of a large mammal. We collected observations of American black bears Ursus americanus (n = 1,315) outside their primary range in Minnesota, USA, as part of a study to gauge population expansion. Participants from the public provided sighting locations of bears on a website. We used an occupancy modelling framework to determine how well ALAN accounted for observer metrics compared to other commonly used metrics (e.g. housing density). Citizen scientists reported 17% of bear sightings were under artificially lit conditions and monthly ALAN estimates did the best job accounting for spatial bias in detection of all observations, based on AIC values and effect sizes (trueβ^ = 0.81, 0.71–0.90 95% CI). Bear detection increased with elevated illuminance; relative abundance was positively associated with natural cover, proximity to primary bear range and lower road density. Although the highest counts of bear sightings occurred in the highly illuminated suburbs of the Minneapolis‐St. Paul metropolitan region, we estimated substantially higher bear abundance in another region with plentiful natural cover and low ALAN (up to ~375% increased predicted relative abundance) where observations were sparse. We demonstrate the importance of considering ALAN radiance when analysing citizen‐scientist‐collected data, and we highlight the ways that ALAN data provide a dynamic snapshot of human activity.

“…Agricultural practices lead to losses of natural resources and biodiversity (Godfray & Garnett, ). One mechanism to minimize the impact of clearing for agriculture and other production activities on biodiversity is to maintain riparian forest strips (insects: Barlow et al, , Brito et al, , Gray, Lewis, Chung, & Fayle, , Gray, Slade, Mann, & Lewis, ; macroinvertebrates: McClain, ; fish: Giam et al, ; birds: Machtans, Villard, & Hannon, , Mitchell et al, , Whitaker & Montevecchi, ; bats: Lloyd, Law, & Goldingay, , Mullin, ; small mammals: Al‐Khudhairy Gutierrez, ; Chapman & Ribic, ; Cockle & Richardson, ; Darveau, Labbe, Beauchesne, Belanger, & Huot, ; large and medium‐sized mammals: Paolino et al, , Phoebus, Segelbacher, & Stenhouse, , Zimbres, Peres, & Machado, ). These strips may become prominent features in agricultural landscapes and may assume disproportionate roles in protecting biodiversity outside protected areas (Arriaga‐Flores, Castro‐Arellano, Moreno‐Valdez, & Correa‐Sandoval, ; Mendenhall, Karp, Meyer, Hadly, & Daily, ; Naiman, Decamps, & Pollock, ).…”

“…Within agricultural landscapes, riparian forest strips may help conserve water resources, improve water quality, harbor animals that serve as bio‐control agents, provide connections between forest fragments, and act as physical barriers to destructive fires, radiation fluxes, winds, and pests (Muscutt, Harris, Bailey, & Davies, ; Saunders, Hobbs, & Margules, ; Zanuncio, Mezzomo, Guedes, & Oliveira, ). In recognition of these benefits, the maintenance of riparian forest strips is supported by legislation in several tropical countries (Barlow et al, ; McClain & Cossio, ; Pereira et al, ) and, in the case of Peru, by Law 29,338 “Hydric Resources Law.” However, the efficacy of riparian forest strips in maintaining biodiversity in cleared agricultural landscapes has been primarily examined in temperate areas (Chapman & Ribic, ; Cockle & Richardson, ; Darveau et al, ; Hagar, ; Machtans et al, ; but see de la Pena‐Cuellar, Benitez‐Malvido, Avila‐Cabadilla, Martinez‐Ramos, & Estrada, ; Lees & Peres, ; Lourenco, Gomes, Pinheiro, Patricio, & Famadas, ; Mitchell et al, ; Paolino et al, ). Given the biodiversity richness of tropical forests, especially lowland wet forests, and the rapid expansion of large‐scale agriculture in these areas, we need additional work to demonstrate the conservation value, if any, of riparian forest strips in tropical regions.…”

Do riparian forest strips in modified forest landscapes aid in conserving bat diversity?

Agricultural practices lead to losses of natural resources and biodiversity. Maintaining forests alongside streams (riparian forest strips) has been used as a mechanism to minimize the impact of clearing for agriculture on biodiversity. To test the contribution of riparian forest strips to conserve biodiversity in production landscapes, we selected bats as a biodiversity model system and examined two dimensions of diversity: taxonomic and functional. We compared bat diversity and composition in forest, with and without stream habitat, and in narrow forest riparian strips surrounded by areas cleared for agriculture. We tested the hypothesis that riparian forest strips provide potential conservation value by providing habitat and serving as movement corridors for forest bat species. Riparian forest strips maintained 75% of the bat species registered in forested habitats. We found assemblage in sites with riparian forest strips were dominated by a few species with high abundance and included several species with low abundance. Bat species assemblage was more similar between sites with streams than between those sites to forests without stream habitat. These results highlight the importance of stream habitat in predicting presence of bat species. We registered similar number of guilds between forest sites and riparian forest strips sites. Relative to matrix habitats, stream and edge habitats in riparian forest strips sites were functionally more diverse, supporting our hypothesis about the potential conservation value of riparian forest strips. Results from this study suggest that maintaining riparian forest strips within cleared areas for agricultural areas helps conserve the taxonomic and functional diversity of bats. Also, it provides basic data to evaluate the efficacy of maintaining these landscape features for mitigating impacts of agricultural development on biodiversity. However, we caution that riparian forest strips alone are not sufficient for biodiversity maintenance; their value depends on maintenance of larger forest areas in their vicinity.
