Abstract:
... Mineral dust is an important type of ice nucleating particles in the troposphere; however, the effects of heterogeneous reactions on ice nucleation (IN) activities of mineral dust remain to be elucidated. A droplet-freezing apparatus (Guangzhou Institute of Geochemistry Ice Nucleation Apparatus, GIGINA) was developed in this work to measure IN activities of atmospheric particles in the immersion f ...
... We summarize >80 accounts of jaguars killed and/or photographed in Arizona during a 160-year period. These accounts include 13 previously unrecorded animals and six contemporary photographic records. The period with most records occurred between 1900 and 1920. Occurrences ranged from Sonoran desertscrub < 1000 m ASL to mixed confer forest at 2,134 m ASL. Every county in Arizona save four had jagua ...

Abstract:
... Eimeria vilasi and E. beecheyi are reported for the first time from the golden-mantled ground squirrel (Callospermophilus lateralis). Eimeria vilasi was found in 12 of 35 (34%), and E. beecheyi in 2 of 35 (6%), golden-mantled ground squirrels in Arizona. Sporulated oocysts of E. vilasi were ovoidal, 18.1 × 15.8 (15–21 × 13–18) µm, with a length/width ratio of 1.1 (1.0–1.3), and 1–4 polar granules. ...

Abstract:
... Stocking of rare native fishes for conservation purposes is a common practice in the southwestern United States. Monitoring typically occurs after hatchery-reared fish are released to assess post-stocking movement and survival. We conducted a two-year study, in which tow-barge electrofishing and portable, flat-bed passive integrated transponder (PIT) antennas were used to monitor PIT-tagged, hatch ...

Abstract:
... A new volcano erupted in the eleventh century AD in the San Francisco volcanic field, which has as many as 80 old volcanoes and 600 eruption cones all centered around Flagstaff, Arizona. This volcanic landscape has been a cultural center for Native American spiritual activities for up to 23,000 years. During that time, they have come to perceive volcanoes as earth navels and thus places where the ...
Arizona, etc ; air; dust; particle size distribution; permeability; prediction; technology; Show all 7 Subjects
Abstract:
... The operating resistance of a high-efficiency particulate air (HEPA) filter is affected by the environment and cannot be obtained through the dust holding capacity (DHC) test in the laboratory. For non-flat HEPA filters, studies on the effect of non-uniform deposition of particles on operating resistance were insufficient. We proposed an equivalent permeability coefficient (EPC) method to calculat ...

Abstract:
... Animals from urban areas are regularly brought into wildlife rehabilitation centers, providing untapped potential data records to inform management of wildlife species. Although rescues may be considered a wildlife stewardship behavior, not all ‘rescues’ may be warranted. Some animals are more likely to be brought into a rescue center than others, suggesting that human drivers underlying wildlife ...

... BACKGROUND: Most physical activity (PA) during school occurs at recess; however, recess PA may be influenced by children’s thermal comfort and interaction with nature, neither of which have concurrently been measured reliably in previous studies. This study tests the reliability of SOPLAY-SN, an adaption of the validated System for Observing Play and Leisure Activity in Youth (SOPLAY) to measure S ...

Abstract:
... Norape sorpresa sp. nov. Wagner & Matson occurs from extreme southeastern Arizona south into Sonora, Mexico. Beyond differences in leg color, adult external features do not allow ready separation of this species from the other two white Norape that occur north of Mexico. However, genital features, COI barcodes, and larval characters distinguish the three taxa. The adult and larval stages and male ...
Arizona, etc ; air temperature; cooling; environment; greenhouse gases; heat; infrastructure; thermosensitivity; urbanization; Show all 9 Subjects
Abstract:
... Cities are facing the twin pressures of greenhouse gas driven climatic warming and locally induced urban heating. These pressures are threatening populations that are sensitive to extreme heat due to sociodemographic factors including economic means. Heat-reducing infrastructure adaptation measures such as reflective “cool” materials can reduce urban temperatures. Here we examine the needs-based e ...

Abstract:
... CONTEXT: There is a long-standing quest in landscape ecology for holistic biodiversity metrics accounting for multi-taxa diversity in heterogeneous habitat mosaics. Passive acoustic monitoring of biodiversity may provide integrative indices allowing to investigate how soundscapes are shaped by compositional and configurational heterogeneity of mosaic landscapes. OBJECTIVES: We tested the effects o ...

Abstract:
... Virus surveillance by wastewater-based epidemiology (WBE) in two Arizona municipalities in Maricopa County, USA (~700,000 people), revealed the presence of six canine picornavirus (CanPV) variants: five in 2019 and one in 2021. Phylogenetic analysis suggests these viruses might be from domestic dog breeds living within or around the area. Phylogenetic and pairwise identity analyses suggest over 15 ...

Abstract:
... The hypsoprorine treehopper Philya ferruginosa (Goding), described from Arizona in 1894, has remained little known. Images of Philya posted recently on the internet represent misidentifications of the Neotropical P. lowryi Plummer, known only from the type locality in south-central Mexico; the records refer to P. ferruginosa. The nymphs and adults of P. ferruginosa we found on New Mexico locust (R ...

Abstract:
... The two most common kissing bugs, Triatoma rubida and T. protracta, in the Sonoran Desert around Tucson, Arizona are hematophagous vectors of Chagas disease and can induce potentially life-threatening allergic reactions. They were surveyed during their summer dispersal flight period to determine which environmental factors are correlated with flight activity. The two most important factors governi ...

Abstract:
... This study aims to expand our understanding of the genetic architecture of crown morphology in the human diphyodont dentition. Here, we present bivariate genetic correlation estimates for deciduous and permanent molar traits and evaluate the patterns of pleiotropy within (e.g., m1–m2) and between (e.g., m2–M1) dentitions. Morphology was observed and scored from dental models representing participa ...

HeatReady Schools are those that are increasingly able to identify, prepare for, mitigate, track, and respond to the negative impacts of schoolground heat. This study set out to 1) improve our understanding of heat perceptions, reactions and actions, and heat safety recommendations of key stake ...

Abstract:
... Bees experience differences in thermal tolerance based on their geographical range; however, there are virtually no studies that examine how overwintering temperatures may influence immature survival rates. Here, we conducted a transplant experiment along an elevation gradient to test for climate‐change effects on immature overwinter survival using movement along elevational gradient for a communi ...

Abstract:
... Determining the efficacy of artificial water developments for desert bighorn sheep (Ovis canadensis mexicana) populations is an important conservation concern as projected climatic changes pose potentially severe effects to the species in the southwestern United States. We monitored daily visitation frequencies and temporal activity patterns of bighorn sheep at 20 water developments on the Barry M ...

Abstract:
... Scavenging appears to be a conserved but flexible characteristic among spiders. Although scavenging behavior is well documented in captivity, observations in the wild are rarely witnessed. During a road ecology survey on 6 September 2021, I observed an adult male desert blonde tarantula (Aphonopelma chalcodes) scavenging upon a roadkilled neonate western diamond-backed rattlesnake (Crotalus atrox) ...

Abstract:
... Between 26 and 28 June 2021, the United States' Pacific Northwest endured an unprecedented heatwave that broke previous temperature records by 5 °C. Here, we report the impacts of the heatwave on Bushtit (Psaltriparus minimus) nests being monitored as part of a long-term study in Portland, Oregon. Of the 8 nests active during the event, nestling mortality was 100% in 3 nests and 4 broods survived ...
