<p>The Last Interglacial (LIG) period (~129,000–116,000 years BP) and the mid-Holocene (MH) (~6,000 years BP) are the two most recent intervals with temperatures comparable to low emissions scenarios for the end of the 21<sup>st</sup> century. During the LIG and the MH differences in the seasonal and latitudinal distribution of insolation led to enhanced northern hemisphere high-latitude warmth relative to the pre-industrial, despite similar greenhouse gas concentrations, marking these intervals as potentially useful analogs for future change in regions like North America. Further, the inclusion of both LIG (127 ka) and MH (6 ka) experiments in the CMIP6-PMIP4 effort provides an opportunity to better understand the regional hydroclimate responses to radiative forcing during these two intervals. The dense coverage of paleoclimate proxy records for North America during the MH (N=260 sites) reveals a pattern of relative aridity in the Pacific Northwest and Western Canada and wetness in the southern Great Basin and Mexico. However, the seasonality and driving mechanisms of rainfall patterns across the continent remain poorly understood. Our understanding of terrestrial hydroclimate in North America during the LIG is more limited (N=39 sites), largely because the LIG is beyond the range of radiocarbon dating.</p><p>Here we present spatial comparisons between output from 14 PMIP4 global circulation models and LIG and MH networks of moisture-sensitive proxies compiled for the North American continent. We utilize two statistical measures of agreement – weighted Cohen’s Kappa and Gwet’s AC2 – to assess the degree of categorical agreement between moisture patterns produced by the models and the proxy networks for each time-slice. PMIP4 models produce variable precipitation anomalies relative to the pre-industrial for both the LIG and MH experiments, often disagreeing on both the sign and magnitude of precipitation changes across much of North America. The models showing the best agreement with the proxy network are similar but not identical for the two measures, with Gwet’s AC2 values tending to be larger than Cohen’s Kappa values for all models. This pattern is enhanced for the much larger MH proxy network and is likely related to the fact that Gwet’s AC2 is a more predictable statistic in the presence of high agreement. Overall agreement is lower for the mid-Holocene than for the LIG, reflecting smaller MH rainfall anomalies in the models. The models with the highest agreement scores during the LIG produce aridity in the Rocky Mountains and Pacific Northwest and wetness in Alaska, the Yukon, the Great Basin, and parts of the Mid-West and Eastern US, although spatial coverage of the proxies in these latter two regions is poor. The models with the highest agreement score for the mid-Holocene tend to produce aridity across Canada and the northern US with dry conditions extending down the US Pacific coast and increased wetness in the American Southeast and across the North American Monsoon region. Our analyses help elucidate the driving mechanisms of rainfall patterns during past warm states and can inform which models may be the most useful for predictions of near-future hydroclimate change across North America.</p>

In a letter to a friend in the United States dated May 16, 1969, a leading Colombian sociologist declared:I have been trying to disattach myself from portions of the North American heritage which I had received, and with which I find myself increasingly at odds. For this reason, I cannot identify myself with any institution of the United States that would uphold or sustain the present economic and social policies pursued toward the Nations of the Third World.

The center of diversity for white pine blister rust (WPBR) (Cronartium ribicola J.C. Fischer) most likely stretches from central Siberia east of the Ural Mountains to Asia, possibly bounded by the Himalayas to the south. The alternate hosts for WPBR, Asian five-needled pines (Pinus L.) and Ribes L. native to that region have developed WPBR resistance. Because the dispersal of C. ribicola to Europe and North America occurred within the last several hundred years, the North American five-needled white pines, Pinus subsections, Strobus and Parya, had no previous selection pressure to develop resistance. Establishment of WPBR in North American resulted when plants were transported both ways across the Atlantic Ocean. In 1705, Lord Weymouth had white pine (P. strobis L.), also called weymouth pine in Europe, seed and seedlings brought to England. These trees were planted throughout eastern Europe. In the mid-1800s, WPBR outbreaks were reported in Ribes and then in white pines in eastern Europe. The pathogen may have been brought to Europe on an infected pine from Russia. In the late 1800s American nurserymen, unaware of the European rust incidence, imported many infected white pine seedlings from France and Germany for reforestation efforts. By 1914, rust-infected white pine nursery stock was imported into Connecticut, Indiana, Massachusetts, Minnesota, New Hampshire, Ohio, Pennsylvania, Vermont, and Wisconsin, and in the Canadian provinces of Ontario, Quebec, and British Columbia. The range of WPBR is established in eastern North America and the Pacific Northwest. New infection sites in Nevada, South Dakota, New Mexico and Colorado have been observed during the 1990s.

One of the greatest archaeological enigmas is in understanding the role of decision-making, intentionality and interventions in plant life cycles by foraging peoples in transitions to and from low-level food production practices. We bring together archaeological, palaeoclimatological and botanical data to explore relationships over the past 4000 years between people and camas ( Camassia quamash ), a perennial geophyte with an edible bulb common across the North American Pacific Northwest. In this region throughout the late Holocene, people began experimenting with selective harvesting practices through targeting sexually mature bulbs by 3500 cal BP, with bulb harvesting practices akin to ethnographic descriptions firmly established by 1000 cal BP. While we find no evidence that such interventions lead to a selection for larger bulbs or a reduction in time to maturity, archaeological bulbs do exhibit several other domestication syndrome traits. This establishes considerable continuity to human intervention into camas life cycles, but these dynamic relationships did not result in unequivocal morphological indications of domestication. This approach to tracking forager plant management practices offers an alternative explanatory framework to conventional management studies, supplements oral histories of Indigenous traditional resource management and can be applied to other vegetatively propagated species.

AbstractThe North American genusCeratagalliaKirkaldy, 1907 is redefined to include subgenusAceratagalliaKirkaldy, 1907 (=IoniaBall, 1933, syn.nov.) with 78 species in two subgenera. Two additional new species are unplaced to subgenus:C. aceratafrom Oregon, andC. emarginatafrom Mexico. The typical subgenusCeratagalliahas 30 species, includingC. gillettei(Osborn & Ball, comb.nov.),C. sordida(Oman, comb.nov.), and two new speciesC. anafrom Mexico andC. viperafrom Washington state. SubgenusAceratagalliahas 46 species, all new combinations underCeratagallia. The economic "species" formerly known as "sanguinolenta" is divided into the Canadian clover leafhopperC. humilis(Oman) and the American clover leafhopperC. agricolasp.nov. Other new taxa in subgenusAceratagalliainclude 18 new species and seven new subspecies:alaskana(ssp. ofsiccifolia)from Alaska;omanion the Pacific coast from Oregon to British Columbia;clinoandlophiafrom the Oregon interior;compressa(ssp. ofsiccifolia),gallus,modesta,okanagana, andzacki(ssp. ofnanella) from intermontane valleys of the Pacific northwest and southwestern mountains;interior(ssp. ofhumilis) androssifrom the Sonoran subregion;australis(ssp. ofnanella),coma,ebena,entoma,falcata,oionus, andvenosafrom Mexico and Texas;alvarana(ssp. ofhumilis),cerea,cristula,harrisi, semiarida, andviatorwidespread between the Appalachian and Rocky Mountains; andwhitcombi(ssp. ofrobusta) from Florida to Arizona. Four former species are reduced to subspecies:compactaOman andpoudrisOman inC. robusta(Oman),helveolaOman inC. cinerea(Osborn & Ball), andtruncataOman inC. humilis. The taxa are keyed and illustrated, and their phylogeny is discussed.

AbstractThe genus Porrhodites Kraatz is redescribed to include the Nearctic Paradeliphrum inflatum Hatch, as well as the Holarctic Porrhodites fenestralis (Zetterstedt). Orochares Kraatz is also redescribed to include Paradeliphrum (new synonymy). In addition to O. angustatus Erichson from Europe, O. japonicus Cameron from Japan and O. villiersi Jarrige from Iran, Orochares now includes two Nearctic species, Paradeliphrum tumidum Hatch from the Pacific Northwest and the new species O. suteri from Illinois and Wisconsin. Keys are provided to distinguish the North American species of each genus, and the major diagnostic characters of all included taxa are illustrated.

Abstract When tropical cyclones in the western North Pacific turn into midlatitude cyclones, it often perturbs the jet stream, resulting in amplified flow conditions in the north Pacific and various weather extremes in North America. Thus far, however, the complex impacts of extratropical transitioning cyclones (ETCs) on North American fire weather are undocumented. In this study, we group ETCs by the characteristics that are important for their interaction with the jet stream and document the response in North American fire weather, finding that ETCs are consistently associated with enhanced fire weather in North America through amplified pressure gradients and anomalous winds. While the chaotic nature of the ETC and jet stream interaction means that ETCs grouped by similar characteristics and locations can result in varying downstream responses, the composite analysis reveals some areas of consistently enhanced fire weather, including the Pacific Northwest and northern Intermountain West. At a time in which the risk and extent of wildfires in the Western United States is an issue of growing concern, this study represents the first holistic understanding of how ETCs’ downstream perturbations impact fire weather.
