“…In some other studies, water retention is affected by the texture of soil (Razzaghi et al, 2020) as some clay minerals like Montmorillonite, iron oxide, vermiculite, and quartz increases the moisture-retaining abilities of clays which further affect the special distribution of forest and grasslands (Riddle and Bateman, 2020). Water held in pore spaces is called hygroscopic water (Martin and Gonzales, 2017).…”

“…Results show the importance of distance to streams was our third most influential variable, with habitat suitability decreasing with increased distance, confirming that riparian zones are important for A. microscaphus (Sullivan, 1992), regardless of elevation or biome. Near stream and riparian habitat use may be most important during the post‐metamorph emergence period, just before summer monsoons, which often coincides with hot summer temperatures because of more shade, higher relative humidity and greater soil moisture than upland areas, especially in dryland systems (Riddle & Bateman, 2020).…”

AimWe propose a combined approach to explore the model transferability and the effect of climate change on habitat suitability.LocationSouthwest United States.TaxonAmphibians; Anura; Bufonidae; Anaxyrus microscaphus.MethodsTo assess the impacts of climate change on A. microscaphus, we obtained 3162 records from the Arizona Game and Fish Department. We classified occurrence records data into six historical groups (from 1960 to 2018) and a contemporary group (from 2019 to 2022). We investigated the ability of historical data to generate accurate predictions of the species' contemporary distribution. We used species distribution modelling to compute habitat suitability values and identified spatial clusters of high suitability values (using hotspot analyses).ResultsWe show that historical occurrences successfully predicted the contemporary distribution of A. microscaphus. We demonstrate that the geographical distribution of contemporary hotspots is strongly related to precipitation of the wettest quarter. This research provides evidence that climate change will likely affect the distribution of hotspots and the habitat suitability of A. microscaphus. Losses of 37%–48% contraction are expected at the margins of the range both in the north and south of the geographic limits.Main ConclusionsWe show that recent past data can be used to predict contemporary species distribution accurately. We highlight that habitat suitability values of A. microscaphus are strongly related to climate, topography and distance to streams. This study provides clear evidence of the negative impacts of climate change on habitat suitability in the Southwest United States drylands. Our approach has applied utility to managers to target survey areas, monitor habitat changes, plan for conservation mitigation measures, conserve stream flows across the species' range and inform recovery if needed. Thus, managers could use previously collected data to predict contemporary species distribution when their occurrence accurately characterizes the species' ecological niche.

Arizona toad (Anaxyrus microscaphus) is a stream‐breeding bufonid of conservation concern in Arizona, New Mexico, Utah, and Nevada. We determined the occupancy and habitat use of the Arizona toad throughout its range. We surveyed 500‐m reaches along perennial and intermittent streams during the summers of 2021 and 2022 (n = 232) in Arizona. We recorded the presence of all toad life stages, focusing on larval stages. We related toad occupancy to broadscale environmental variables, including measures of bioclimate, habitat heterogeneity, solar radiation, and topography. We collected fine‐scale variables to summarize vegetation cover and substrate within plots (n = 53). We applied multiple occupancy models. Single‐species model results found low toad occupancy with high detection. Two principal component analyses (PCA) were run on broadscale and fine‐scale variables to reduce the number of variables included in the models. Toad occupancy was best predicted by top models with bioclimatic components; occupancy decreases with extremely hot temperatures and less precipitation. A logistic regression related toad presence to fine‐scale components with top models describing riparian complexity and algae. Arizona toads were selected for areas with foliar canopy cover, shallow water, algae cover, and pebble substrates. Arizona toad is an uncommon species and maintaining riparian forests of complex habitats with shallow and side‐channel flow will be important for toad conservation. Implications of less water cause riparian habitat to dry, which ultimately harms aquatic life.
