“…Moreover, data from another citizen science driven wet/dry mapping program in Europe have been used to study intermittent river ecology (Datry et al 2016). Thus, these wet/dry mapping programs are part of a growing trend of relying on citizen scientists to collect freshwater monitoring data (Clavero et al 2017, Lévesque et al 2017, Vincent et al 2017. We used citizen science data in our study to find that landscape intermittency indices produced by wet/dry mapping data can be predicted by streamflow metrics derived from discharge data collected on the same river.…”

Intermittent rivers are spatially dynamic, expanding and contracting in response to changes in water availability, but studies that explicitly examine spatial drying patterns are scarce. We used long-term data produced by citizen scientists to map wet and dry reaches of 3 different river systems to investigate mechanisms producing temporal variation in drying patterns. We quantified the total wetted river length in each survey, and calculated ecologically scaled landscape indices that indicate the carrying capacity (population size) and habitat connectivity of large and small fish metapopulations in these systems. We found that the spatial extent of perennial water decreased over the study period in 2 of the 3 study rivers: ∼26% in the Agua Fria River from 2008 to 2016, and ∼14% in Cienega Creek from 2006 to 2016. We also observed an ∼8% decline in habitat connectivity for large fish in the Agua Fria River. We used multivariate structural equation models to infer causal relationships between spatial drying patterns and temperature, precipitation, streamflow, and drought conditions. These models explained 85% of year-to-year variation in the total length of wet reaches, and 63 and 55% of year-to-year variation in habitat connectivity for large and small fish, respectively. With the US Southwest shifting to an even more arid climate, our results suggest that this may reduce habitat connectivity of fish populations in this region.

“…This database can nevertheless be useful to: improve existing scientific knowledge in Iberian context (e.g., Clavero and Hermoso 8 , Clavero, et al . 11 ); expand scientific knowledge in European context via an Iberian occurrence scenario of a species with broad-European distribution (e.g., Filipe, et al . 12 ); be used for research where historical interactions between human activities and riverine fish communities and population are relevant.…”

One millennium of historical freshwater fish occurrence data for Portuguese rivers and streams

The insights that historical evidence of human presence and man-made documents provide are unique. For example, using historical data may be critical to adequately understand the ecological requirements of species. However, historical information about freshwater species distribution remains largely a knowledge gap. In this Data Descriptor, we present the Portuguese Historical Fish Database (PHish–DB), a compilation of 2214 records (557 at the basin scale, 184 at the sub-basin scale and 1473 at the segment scale) resulting from a survey of 194 historical documents. The database was developed using a three-scale approach that maximises the inclusion of information by allowing different degrees of spatial acuity. PHish database contains records of 25 taxonomical groups and covers a time span of one millennium, from the 11th until the 20th century. This database has already proven useful for two scientific studies, and PHish further use will contribute to correctly assess the full range of conditions tolerated by species, by establishing adequate benchmark conditions, and/or to improve existing knowledge of the species distribution limits.

“…Anglers have long participated in a variety of citizen efforts including the collection of water quality and fish population data (Williams et al 2016), yet there is relatively little peer-reviewed literature describing fisheries projects that incorporated angler harvest as a method to collect data for science. Citizen scientist contributions to fisheries data collections are typically limited to reporting visual observations of fishes (Chin 2014;Thorson et al 2014;Edgar et al 2017), self-reporting recreational catch data (Kovačić and Svensen 2018), locating historical records (Clavero et al 2017), or watching recorded underwater videos to observe fishes (Aguzzi et al 2015). At times, resource managers will externally tag fish and release them back into the fishery, and then rely on anglers to report (often with low participation) when and where a tagged fish was caught (Miranda, Brock, and Dorr 2002).…”

We surveyed 105 St. Louis River Estuary (SLRE) ice-anglers near Duluth, MN, USA to quantify their interest in participation in a harvest-based citizen science program. This hypothetical program would allow anglers to participate in the generation of scientific knowledge about their fishery, while still taking their fillets home. It would also provide researchers with specimens, mostly walleye (Sander vitreus), to gather data typically requiring euthanized fish (determining sex prior to spawn, diet studies, otoliths for aging and microchemistry, etc.). Our data suggests that most anglers (96% of in-person responses and 92% of online responses) would be interested in participating if fish processing stations were located close to their ice-fishing location. The majority of anglers (95% of in-person responses and 77% of online responses) indicated that receiving a personalized end-of-season report summarizing the information gained from their fish-harvest contributions would make them more likely to participate. These results imply that the hypothetical program could be successful within the SLRE with the proper selection of locations, advertisement, and plans for sharing information. This study has implications that may be useful for researchers and managers of other fisheries with an ample and engaged angling community. Despite some challenges to this approach, it has the potential to be a legitimate method for acquiring fisheries research materials, and at the same time strengthen anglers' trust of managing institutions.
