Scenario Planning Management Actions to Restore Cold Water Stream Habitat: Comparing Mechanistic and Statistical Modeling Approaches

ABSTRACTUnder the United States Clean Water Act, states are required to periodically assess state waters to determine compliance with water quality criteria (including temperature) and then to develop total maximum daily loads (TMDLs) for impaired waters as necessary to bring them into compliance. We compared the performance of mechanistic stream temperature models (HeatSource, QUAL2K, and QUAL2Kw) applied to the mainstem of three TMDL watersheds (Middle Fork John Day, OR; Wind River, WA; South Fork Nooksack, WA) with that of spatial stream network (SSN) models applied to the full watersheds and used these to evaluate the potential effectiveness of restoration strategies. SSN models performed well with slightly lesser accuracy (RMSE = 0.47–0.87) for mainstem predictions than mechanistic models (RMSE = 0.4) but provided additional benefits to inform management, including information on spatial and temporal heterogeneity of restoration effectiveness throughout the watershed. Of the four scenarios considered (restoration of riparian zones to potential natural vegetation, channel narrowing, increasing flow by restricting irrigation withdrawals, and combined applications), riparian zone restoration was consistently the most effective in reducing temperatures at the outlet, mainstem, and throughout the watersheds. Predicted restoration effectiveness for thermal regimes varied significantly both within and among watersheds. A focus on water quality criteria exceedance only at the watershed outlet or along the mainstem reach can obscure knowledge of restoration potential for fish habitat in tributaries and headwaters, potential for creation of thermal refuge areas along the mainstem critical for maintaining migration corridors, and thermal regime heterogeneity across space and time.

The Politics of Sport: John Day's The Isle of Gulls

This article explores three scenes in John Day’s understudied satiric drama The Isle of Gulls, reading the royal hunt, game of bowls, and double jest as examples of a cultural phenomenon that disguises politics as recreation.

Untangling the Magelonidae (Annelida: Polychaeta) of southern Africa, including the description of a new species

‘A monograph on the Polychaeta of Southern Africa’ by J. H. Day, published in 1967 and covering over 700 species, was considered an essential reference text for marine biologists. Nonetheless, despite the major contribution it has made, we now know that the biodiversity of Polychaeta (commonly known as bristleworms) in southern Africa has been underestimated by more than 500 species. As one of the top 20 polychaete families highlighted as requiring revision in southern Africa, direct observation of magelonids in the collections of Iziko Museums of South Africa and Natural History Museum, London identified by John Day, and additional material has been carried out. This has revealed that the original description of Magelona capensis was based on two species. Consequently, an additional redescription of the holotype of M. capensis is provided herein, and the additional material is described as Magelona ekapa sp. nov. The new species shares similarities with eight species comprising the ‘Magelona pitelkai group’, which is further discussed. A redescription of M. cincta is also provided based on the holotype and freshly collected material. A specimen from Morrumbene Estuary, southern Mozambique, originally identified as M. cincta likely represents an undescribed species: images and a description are provided here, but the species will remain undescribed until further material becomes available. A dichotomous indentification key and a table of characters is provided for all known southern African species of the Magelonidae.

Effects of Anthropogenic and Climate-Induced Habitat Changes on Adult Female Mule Deer Survival

Increased wildfire size and frequency, invasion of non-native annual grasses, extensive fire suppression, climate change, and widespread juniper expansion have led to dramatic changes in sagebrush ecosystems, which provide habitat for a suite of wildlife species, including mule deer (Odocoileus hemionus). These landscape-level disturbances can cause habitat loss and degradation, which influence the quantity and quality of available forage and can negatively influence adult female mule deer survival. We used Program MARK to estimate survival rates using a known-fate model. Our dataset included 111 radio-collared female mule deer to estimate monthly survival rates and to investigate factors that may affect these rates, including movement behavior (migratory or resident) and habitat characteristics (wildfire and juniper canopy cover) in mule deer habitats supporting sagebrush potential vegetation types (PVTs). The dataset included 116 421 Global Positioning System (GPS) location points from 2015 to 2017 in the John Day Basin, Oregon, United States. Survival averaged 0.78 (95% confidence interval = 0.61–0.82) across the study period but was 0.69 (95% confidence interval = 0.59–0.77) in 2015. Our results indicated survival was positively influenced by the presence of small amounts of recent fire (< 15% of total winter range burned; 1−20 yr postfire) within an individual's winter range. Annual survival (0.78) was low compared with survival rates for adult female mule deer in other parts of their geographic range. These findings demonstrate how postfire vegetation response can have a positive effect on mule deer survival, regardless of their migration strategy. Our findings also indicate how climate change poses a growing threat to mule deer populations as prolonged periods of drought increase the spread of fatal diseases.

Two Asian cricetodontine-like muroid rodents from the Neogene of western North America

AbstractWe appraise the morphology and potential origin of two Neogene cricetodontine-like muroids, Pliotomodon primitivus from Late Miocene sediments in northern California and an undescribed muroid from the late Oligocene or Early Miocene of central Oregon. Superficial resemblance of the dentition of Pliotomodon with members of the North American galushamyinan neotominins is considered a result of parallel evolution, as shown by the large size and unreduced M3/m3 of the former. Dental features of Pliotomodon are similar to those of Eurasian genera such as Byzantinia, Hispanomys, and Ruscinomys, but the unusual morphology of M3/m3, with continuous enamel connections across their lingual surfaces closing the hypoflexus and posteroflexid, respectively, plus retention of only three roots on M1, suggests Pliotomodon arose from an ancestor distinct from the one that gave rise to the large late Neogene hypsodont cricetodontines of the Old World. In the absence of known ancestral taxa in North America, we postulate Pliotomodon dispersed to North America across Beringia during the Hemphillian (ca. 8.6 Ma, Hh-1). Another archaic cricetodontine-like rodent, from the Warm Springs region of the John Day Formation in Oregon, is named as a new species of Deperetomys, D. dingusi new species. Deperetomys dingusi n. sp. likely descended from a species of Deperetomys intermediate between archaic species such as D. calefactus and D. magnus and more dentally derived species such as D. intermedius and D. hagni, dispersing to North America during the late Oligocene or Early Miocene (Arikareean; ca. 23 Ma, Ar3 or Ar4).UUID: http://zoobank.org/b691db3a-79de-4d3e-8af0-3bda4957b119

Accuracy and ‘Error’ in the Production of John Foxe and John Day’s Acts and Monuments

Abstract This essay focuses upon John Foxe and John Day’s approach to the correction of error in the production of successive editions of Acts and Monuments, especially through the use of slip-cancels, tiny scraps of paper which are intended for pasting over erroneous text, as well as the use of stop-press correction and the labeling of the book’s well-known woodcut illustrations. The bibliographical nature of successive editions of Foxe’s book overseen by Day emerges as even more complex than previously described. The argument adds to scholarly understanding of the goals and methodologies of both Foxe and Day. Bibliographical fluidity associated with John Day’s approach to error during production points toward the better understanding of textual fluidity within successive editions of Foxe’s work.

The earliest dipodomyine heteromyid in North America and the phylogenetic relationships of geomorph rodents.

Dipodomyine heteromyids (kangaroo rats and mice) are a diverse group of arid-adapted ricochetal rodents of North America. Here, a new genus and species of a large dipodomyine is reported from early Miocene-aged deposits of the John Day Formation in Oregon that represents the earliest record of the subfamily. The taxon is known from a single specimen consisting of a nearly complete skull, dentary, partial pes, and caudal vertebra. The specimen is characterized by a mosaic of ancestral and highly derived cranial features of heteromyids. Specifically, the dental morphology and some cranial characteristics are similar to early heteromyids, but other aspects of morphology, including the exceptionally inflated auditory bullae, are more similar to known dipodomyines. This specimen was included in a phylogenetic analysis comprising 96 characters and the broadest sampling of living and extinct geomorph rodents of any morphological phylogenetic analysis to date. Results support the monophyly of crown-group Heteromyidae exclusive of Geomyidae and place the new taxon within Dipodomyinae. The new heteromyid is the largest known member of the family. Analyses suggest that large body size evolved several times within Heteromyidae. Overall, the morphology of the new heteromyid supports a mosaic evolution of the open-habitat adaptations that characterize kangaroo rats and mice, with the inflation of the auditory bulla appearing early in the group, and bipedality/ricochetal locomotion appearing later. We hypothesize that cooling and drying conditions in the late Oligocene and early Miocene favored adaptations for life in more open habitats, resulting in increased locomotor specialization in this lineage over time from a terrestrial ancestor.

The Sexual Politics of Paratexts: John Day’s Gorboduc

Abstract Because Gorboduc, or The Tragedie of Ferrex and Porrex (1561) sees a king divide his kingdom between his two sons while he still lives, much scholarship discusses the play as an Elizabeth succession parable. However, the printer John Day’s prefatory letter to his 1570 octavo (O2) provides a different frame, documenting an instance of Gorboduc’s later reception that scholarship has not yet recognized. This article argues that by comparing the playtext to a sexually assaulted woman Day does not merely advertise his edition’s supposed superiority to O1, as some have claimed. Considering Day’s reformist network, his investment in preserving Protestantism in England, and his output in 1570—including the massive second edition of Foxe’s Actes and Monuments and political treatises by Gorboduc’s co-author Thomas Norton—Day’s ‘better forme’ of Gorboduc becomes newly legible within histories of reading. For by claiming O2 will ‘play Lucreces part’, Day reads Gorboduc’s materialization of misrule’s effects through violence against ‘Mother Brittaine’ as anti-tyranny polemic—and asks book buyers to read it this way as well. Synthesizing historicist and feminist literary approaches with recent book historical work on paratexts, this article demonstrates how O2’s prefatory letter figures gender violence to justify resistance to tyranny.

The streamwater microbiome encodes hydrologic data across scales

Many fundamental questions in hydrology remain unanswered due to the limited information that can be extracted from existing data sources. Microbial communities constitute a novel type of environmental data, as they are comprised of many thousands of taxonomically and functionally diverse groups known to respond to both biotic and abiotic environmental factors. As such, these microscale communities reflect a range of macroscale conditions and characteristics, some of which also drive hydrologic regimes. Here, we assess the extent to which streamwater microbial communities (as characterized by 16S gene amplicon sequence abundance) encode information about catchment hydrology across scales. We analyzed 64 summer streamwater DNA samples collected from subcatchments within the Willamette, Deschutes, and John Day river basins in Oregon, USA, which range 0.03–29,000 km2 in area and 343–2334 mm/year of precipitation. We applied information theory to quantify the breadth and depth of information about common hydrologic metrics encoded within microbial taxa. Of the 256 microbial taxa that spanned all three watersheds, we found 9.6 % (24.5/256) of taxa, on average, shared information with a given hydrologic metric, with a median 15.6 % (range = 12.4–49.2 %) reduction in uncertainty of that metric based on knowledge of the microbial biogeography. All of the hydrologic metrics we assessed, including daily discharge at different time lags, mean monthly discharge, and seasonal high and low flow durations were encoded within the microbial community. Summer microbial taxa shared the most information with winter mean flows. Our study demonstrates quantifiable relationships between streamwater microbial taxa and hydrologic metrics at different scales, likely resulting from the integration of multiple overlapping drivers of each. Streamwater microbial communities are rich sources of information that may contribute fresh insight to unresolved hydrologic questions.

A ‘partial’ Orientalist

Abstract Lin Yutang 林语堂 (1895–1976) was a Chinese American writer based in the USA who produced thirty English works interpreting Chinese philosophy to a western audience between 1936 and 1966. Lin’s critics often accuse him of succumbing to colonial power dynamics between China and the west. Famous Chinese Short Stories: Retold by Lin Yutang (FCSS), published by the John Day Company in 1952, is a particularly revealing case in point. FCSS contains twenty tales selected from ancient Chinese culture, edited, and rewritten in English using western storytelling techniques. In response to critiques of Lin’s works including FCSS as being Orientalist, I re-examine the intricate process of Lin’s rewriting to reveal a more complex stance vis-à-vis Orientalism, characterizing his cultural position as that of a ‘partial’ Orientalist. This term implies that Lin recognizes the potential of Chinese tradition to provide an alternative modernity.

First occurrences of Palaeogale von Meyer, 1846 in the Pacific Northwest, United States

The feliform carnivoran Palaeogale von Meyer, 1846 first appears in the Eocene of North America and had a Holarctic distribution in the Oligocene and early Miocene. Despite its large range, Palaeogale has not previously been reported from the Pacific Northwest of North America. We report three new specimens from the John Day Basin of Oregon that fill in this geographic gap. The oldest of these is a largely complete cranium from the Turtle Cove Member of the John Day Formation (Oligocene, 30.0-28.9 Ma). The other two specimens are a left and a right dentary from separate individuals, both recovered from the Kimberly Member (Oligocene, 25.3-23.5 Ma). Because Palaeogale species are almost entirely distinguished by their lower dentition, the cranium cannot be identified to species. However, the cranium is the oldest occurrence of the genus in the Pacific Northwest. The absence of a posterior accessory cusp on the p4 and of lateral expansion of the m1 protoconid allows the dentaries to be assigned to an endemic North American species, P. dorothiae MacDonald, 1963. This is not only the first instance of this species in the Pacific Northwest and outside of South Dakota and Nebraska, but also the last known occurrence of P. dorothiae. We expect that these specimens will inform future analyses of phylogenetics, systematics, morphology, and biogeography in Palaeogale.

John Day’s Production of Woodcut Prints from John Foxe’s Acts and Monuments

Abstract Scholars have long suspected the existence of John Day’s independent commercial trade in woodcut prints from the illustrations of Foxe’s Acts and Monuments. This essay supplies bibliographical evidence in support of this hypothesis. The evidence consists of changes in typesetting found within the textblocks and captions used to identify the images, as well as deterioration patterns discernable within Foxe woodcuts used from the first (1563) to seventh (1631–32) editions of Acts and Monuments. By examining surviving examples of prints which Day included within successive editions, the analysis reveals that some prints are almost certainly not original to Day’s manufacture of the books which now preserve them, or to any other known early edition. Instead, some copies of these prints appear to have been inserted within books at the time of manufacture, most likely by Day, who drew upon a pre-existing stock of prints which he had independently manufactured.

Mineralogy and diagenesis of Mars-analog paleosols from eastern Oregon, USA

Ancient (4.1–3.7-billion-year-old) layered sedimentary rocks on Mars are rich in clay minerals which formed from aqueous alteration of the Martian surface. Many of these sedimentary rocks appear to be composed of vertical sequences of rocks containing Fe/Mg clay minerals overlain by rocks with Al clay minerals that altogether resemble paleosols (ancient, buried soils) from Earth. The types and properties of minerals in paleosols can be used to constrain the environmental conditions during formation to better understand weathering and diagenesis on Mars. This work examines the mineralogy and diagenetic alteration of volcaniclastic paleosols from the Eocene-Oligocene (43–28 Ma) Clarno and John Day Formations in eastern Oregon as a Mars-analog site. Here, paleosols rich in Al phyllosilicates and amorphous colloids overlie paleosols with Fe/Mg smectites that altogether span a sequence of ~ 500 individual profiles across hundreds of meters of vertical stratigraphy. Samples collected from three of these paleosol profiles were analyzed with visible/near-infrared (VNIR) spectroscopy, X-ray diffraction (XRD), and evolved gas analysis (EGA) configured to operate like the SAM-EGA instrument onboard Curiosity Mars Rover. Strongly crystalline Al/Fe dioctahedral phyllosilicates (montmorillonite and nontronite) were the major phases identified in all samples with all methods. Minor phases included the zeolite mineral clinoptilolite, as well as andesine, cristobalite, opal-CT and gypsum. Evolved H2O was detected in all samples and was consistent with adsorbed water and the dehydroxylation of a dioctahedral phyllosilicate, and differences in H2O evolutions between montmorillonite and nontronite were readily observable. Detections of hematite and zeolites suggested paleosols were affected by burial reddening and zeolitization, but absence of illite and chlorite suggest that potash metasomatism and other, more severe diagenetic alterations had not occurred. The high clay mineral content of the observed paleosols (up to 95 wt%) may have minimized diagenetic alteration over geological time scales. Martian paleosols rich in Al and Fe smectites may have also resisted severe diagenetic alteration, which is favorable for future in-situ examination. Results from this work can help differentiate paleosols and weathering profiles from other types of sedimentary rocks in the geological record of Mars.

The first records of &lt;i&gt;Sinclairella&lt;/i&gt; (Apatemyidae) from the Pacific Northwest, USA

Apatemyidae are a rare and enigmatic group of small insectivorous mammals that lived in North America and Europe in the Paleogene. The last known apatemyids in North America are two species in the genus Sinclairella, known from sites in the Great Plains and Florida. Here, I formally describe an upper second molar and lower incisor of the apatemyid, Sinclairella dakotensis, from the incredibly well-studied Turtle Cove Member of the John Day Formation in Oregon. These early Arikareean age specimens represent the first records of the family west of the Rocky Mountains. Sinclairella dakotensis filled a ‘woodpecking’ niche unlike any other mammal known from the region, and its co-occurrence with a number of forest-adapted mammal species is consistent with previous interpretations of environments at the time having been dominated by woodlands.
