Abstract:
We report and describe the first species of Atheroides Haliday presumed to be native to North America, collected at the Valles Caldera National Preserve, New Mexico, USA. We hypothesize its placement among the Siphini based on morphological, phylogenetic analysis and extend the distribution of the genus to the Holoarctic. We expand the key of the known Atheroides to include the new species and discuss the current hypotheses of the geographic distribution of the type species, Atheroides serrulatus Haliday.

Abstract:
Catastrophic wildfire is increasingly common in forests of the western United States because climate change is increasing ambient temperatures and periods of drought. In 2011, the Las Conchas wildfire burned in the Santa Fe National Forest of New Mexico, including portions of ponderosa pine and mixed-conifer forests, and grasslands in the Valles Caldera National Preserve, a large, high-elevation volcanic caldera. Following the fire, Caldera staff began monitoring abiotic, plant, and animal responses. In this study, ground-dwelling arachnids were collected in pitfall traps in burned and unburned habitats from 2011–2015. Permutational multivariate analysis of variance (PERMANOVA) mostly at the genus level with some higher taxon levels showed significant fire, year, and interaction effects. Abundance was at or near unburned levels by 2014, but species composition changed in burned areas. Pardosa and Haplodrassus were dominant genera across habitats. Linyphiids were strong indicators of unburned sites. Harvestmen were among the dominant species in the forest habitats, and erythraeid mites were abundant in the burned ponderosa pine forest and the grassland. Years were not significantly autocorrelated, unsurprising given the interannual variation in precipitation in this generally arid region. Although fire is a common feature of these habitats, future fires may be outside of historical patterns, preventing spider communities from re-establishing fully.

Full text
Abstract:
Valles Caldera National Preserve (VCNP) managers were concerned about low elk recruitment observed at the same time as an apparent increase in sightings of coyotes and observations of coyote predation on elk calves. The goal of this study was to describe coyotes’ ecological interactions with elk, particularly coyote diet and movements on the Valle Grande, a large grassland meadow in the southeastern portion of the VCNP. We examined coyote diet by quantifying undigested remains of food items in coyote scats (feces). The most frequent taxa were rodents (montane voles and pocket gophers), elk (adult and calf), insects (grasshoppers and beetles), mountain cottontail rabbits, and plants. Most food types varied significantly seasonally and annually, likely due to climatic variation and the relative availability or vulnerability of food items. In particular, an increase in calf elk consumed during summer 2006 followed a dry winter when elk may have been in a lower nutritional state. We analyzed locations of 33 coyotes, obtained via global positioning system (GPS) collars and radio-tracking. We classified 23 coyotes as residents, living with a social group in a defined area (11.0 km2 mean), and 10 coyotes as transient, with less fidelity to specific areas and often travelling around the edges of the areas occupied by the four resident packs. Coyotes spent most of their time in dry meadow habitat. Coyotes spent more time in riparian habitat than expected based on its availability within home range and less time in forests. We found no relationship between coyote social cohesion (proximity of pack members to each other) and the proportion of elk in coyote diets. We concluded that coyote sociality on VCNP was relatively stable year-round despite changes in biological needs and prey size.

Abstract:
Montane ecosystems of the western United States have experienced dramatic changes in their fire regimes over the last 150 years. Fire behavior modeling enables understanding of how ecosystem changes have altered past fire regimes. The Valles Caldera National Preserve in the Jemez Mountains, northern New Mexico, contains one of the largest montane grasslands in North America. This area is used for multiple uses ranging from logging to grazing and recreation. These important ecosystems have experienced increased fuel loads and stem densities resulting from a century of fire exclusion and tree encroachment, resulting in potentially anomalous fire behavior. We investigated whether fire pathways tend to spread along the grassland-forest ecotone or if fire would spread directly across grasslands under extreme fire weather conditions. We used the program FlamMap to model fire behavior under a variety of weather and fuel conditions. Fire spread pathways and burn perimeters were computed for the 50th, 90th, and 99th percentiles of historic weather conditions. The results are compiled into a probability surface that represents the most parsimonious pathways of fire spread in this landscape. We found that pathways were related to the origin of ignition; fires tended to spread around the ecotone, facilitating fire spread to adjacent grasslands. These results, complemented with fire history studies in dendrochronology and empirical observations of the Las Conchas Fire in 2011, further the understanding of the role and dynamics of fire in maintaining the montane-grassland conifer ecotone, and can guide efforts to restore a landscape affected by the effects of fire exclusion.

Abstract:
The purpose of this study is to examine the interactions between physical and biological processes, and their influence on nutrient cycling and export in two semiarid, montane, headwater catchments. We measured stream chemistry in two neighboring catchments within the Valles Caldera National Preserve, New Mexico from February through August 2005 to identify (1) how variable water sources and flowpaths affect carbon and nutrient concentrations, and (2) how these solutes were modified as they were transported out of the catchments. Both catchments were characterized by a large snowmelt flush of carbon and nutrients in spring and a smaller flush of carbon and nutrients during the monsoon season. Although similar in elevation, soil, vegetation, and climate, the catchments exhibited significantly differences in stream water C, N, and P concentrations during the spring flush. End member mixing using conservative solutes identified the cause of this variability was due primarily to differences in hydro logic residence time and streamflow generation between catchments. These mixing models for each catchment indicated that variability in carbon and nutrients was explained by physical transport during the spring snowmelt and the first flushing events of the monsoon season. In contrast, conservative mixing did a poor job of predicting carbon and nutrient chemistry during other season suggesting biological modification during transport was a major control on streamwater chemistry. After correcting for variability in water sources, both catchments exhibited higher than expected N concentrations during winter and snowmelt, switching to higher than expected P concentrations during the summer monsoon season suggesting a seasonal switch in limiting nutrients. These data demonstrate how simple, quantitative evaluation of hydrologic flowpaths and residence time can be used to separate physical and biological controls on catchment-scale stream water chemistry.

Full text
Abstract:
I quantified the competing effects of forest vegetation on snow accumulation and ablation in a lower mid-latitude montane environment where solar radiation dominates winter snow-atmosphere energy fluxes and limited work has been focused. Detailed snowpit analyses and ultrasonic snow depth sensors indicated forest vegetation affected snowcover in three ways; canopy interception and sloughing, enhanced snowpack metamorphism and ablation, and shading of direct solar radiation. Competing accumulation and melt processes determine the snow cover duration, SWE yield, and potential meltwater inputs. On average, canopy interception resulted in 44% less SWE accumulating beneath the canopy. I observed an inverse correlation between snowpack density and grain size with distance from the tree bole at maximum accumulation. Larger grains and lower densities near the bole indicated enhanced metamorphism of the near tree snowpack. Snow surveys around 15 trees at max accumulation indicated that the north sides of trees had 24.6% (p=0.01) more SWE than south tree sides. Micro- to tree scale observations support our stand and catchment-scale finding that a shaded snowpack experiences increased SWE accumulation, decreased ablation and melt rates, and prolonged seasonal snow cover. Specifically, we found that vegetative shading may delay the basin average maximum SWE accumulation by up to three weeks and greatly increase snow cover duration by minimizing snowmelt rates. Data point to compelling differences in forest ablation and melt processes in this lower mid-latitude where enhanced insolation augments the physical processes observed elsewhere. A binary regression tree model indicated strong correlation (R 2 = 0.54) between micro-scale (i.e. 10-cm resolution) canopy structure indices and snow depth, suggesting that future remotely sensed vegetation data may improve snow distribution models. A better understanding of the effects of forest cover on a basin's snowpack will prepare us to more accurately predict the potentially wide-ranging hydrologic impacts of climate, land cover, and land use change in these seasonally snow covered forested environments.

Abstract:
Although forest properties are known to influence snowpack accumulation and spring runoff, the processes underlying the impacts of forest canopy cover on the input of snowmelt to the catchment remain poorly characterized. In this study I show that throughfall and canopy shading can combine to result in maximal snowpacks in forests of moderate canopy density. Snow depth and density data taken shortly before spring melt in the Jemez Mountains of New Mexico show strong correlation between forest canopy density and snow water equivalent, with maximal snow accumulation in forests with density between 25 and 45%. Forest edges are also shown to be highly influential on local snow depth variability, with shaded open areas holding significantly deeper snow than either unshaded open or deep forest areas. These results are broadly applicable in improving estimates of water resource availability, predicting the ecohydrological implications of vegetation change, and informing integrated water resources management.

Abstract:
River-groundwater exchange (hyporheic exchange) influences temperature, water chemistry, and ecology within rivers and alluvial aquifers. Rates and patterns of hyporheic exchange depend on riverbed permeability, pressure gradients created by current-obstacle interactions, and river stage fluctuations. I demonstrate the response of hyporheic exchange to three examples of these driving forces: fine-scale permeability structure in cross-bedded sediment, current interactions with large woody debris (LWD), and anthropogenic river stage fluctuations downstream of dams. Using numerical simulations, I show that cross-bedded permeability structure increases hyporheic path lengths and modifies solute residence times in bedforms. The tails of residence time distributions conform to a power law in both cross-bedded and internally homogeneous riverbed sediment. Current-bedform interactions are responsible for the decade-scale tails, rather than permeability heterogeneity. Like bedforms, wood debris interacts with currents and drives hyporheic exchange. Laboratory flume experiments and numerical simulations demonstrate that the amplitude of the pressure wave (and thus hyporheic exchange) due to a channel-spanning log increases with channel Froude number and blockage ratio (log diameter : flow depth). Upstream from LWD, downwelling water transports the river’s diel thermal signal deep into the sediment. Downstream, upwelling water forms a wedge of buffered temperatures. Hyporheic exchange associated with LWD does not significantly impact diel surface water temperatures. I tested these fluid and heat flow relationships in a second-order stream in Valles Caldera National Preserve (NM). Log additions created alternating zones of upwelling and downwelling in a reach that was previously losing throughout. By clearing LWD from channels, humans have reduced hydrologic connectivity at the meter-scale and contributed to degradation of benthic and hyporheic habitats. Dams also significantly alter hydrologic connectivity in modern rivers. Continuous water table measurements show that 15 km downstream of the Longhorn dam (Austin, Texas), river stage fluctuations of almost 1 m induce a large, unsteady hyporheic exchange zone within the bank. Dam-induced hyporheic exchange may impact thermal and geochemical budgets for regulated rivers. Together, these three case studies broaden our understanding of complex drivers of hyporheic exchange in small, natural streams as well as large, regulated rivers.<br>text

Abstract:
Valles Caldera National Preserve (VALL) encompasses 35,977 ha (88,900 ac) in the Jemez Mountains of north-central New Mexico and is surrounded by the Santa Fe National Forest, the Pueblo of Santa Clara, and Bandelier National Monument. VALL’s explosive volcanic origin, about 1.23 million years ago, formed the Valles Caldera—a broad, 19- to 24-km (12- to 15-mi) wide circular depression. It is one of the world’s best examples of a young caldera (in geologic time) and serves as the model for understanding caldera resurgence worldwide. A series of resurgent eruptions and magmatic intrusive events followed the original explosion, creating numerous volcanic domes in present day VALL—one of which is Redondo Peak at an elevation of 3,430 m (11,254 ft), which is the second highest peak in the Jemez Mountains. In fact, VALL in its entirety is a high-elevation preserve that hosts a rich assemblage of vegetation, wildlife, and volcanic resources. The National Park Service (NPS) Natural Resource Condition Assessment (NRCA) Program selected VALL to pilot its new NRCA project series. VALL managers and the NRCA Program selected seven focal study resources for condition evaluation. To help us understand what is causing change in resource conditions, we selected a subset of drivers and stressors known or suspected of influencing the preserve’s resources. What is causing change in resource conditions? Mean temperatures during the spring and summer months are increasing, but warming is slower at VALL than for neighboring areas (e.g., Bandelier National Monument). The proportion of precipitation received as snow has declined. From 2000 to 2018, forest pests damaged or killed 75% of the preserve’s forested areas. Only small, forested areas in VALL were affected by forest pests after the 2011 Las Conchas and the 2013 Thompson Ridge fires. The all-sky light pollution model and the sound pressure level model predict the lowest degree of impacts from light and sound to be in the western half of the preserve.
