The Effects of Hackberry Psyllids on Refueling Migratory Songbirds and Autumnal Seed Rain
<p>Hackberry psyllids (<em>Pachypsylla sp</em>) are a galling insect native to North America’s hackberry trees (<em>Celtis sp</em>). Hackberry leaf-galling psyllids are ephemerally abundant during autumn, a period of time when migratory songbirds are traveling from their breeding areas in temperate …

Environmental Influences on Tree-driven Karst Bedrock Physical Weathering
… the root-rock interface for an American elm and Hackberry tree between September 2019 and May 2020. I used piezoelectric force sensors to determine if differences in species, tree size, the distance of roots from the tree, wind or precipitation conditions affected the frequency or magnitude of …

Application of thermocouple psychrometers to field measurements of soil moisture potential.
… The effect of Celtis pallida (desert hackberry), a native plant species, on the soil moisture regime is described. Moisture uptake by the plant, and precipitation input to the soil near the plant are described in terms of the potential variations they produce. The particular hackberry …

Mammal Damage and Movements of Deer Mice in South Dakota Shelterbelts
… mice moved significantly more in green ash and hackberry (Celtis occidentalis L. ) than other tree species.</p>

Comparison of Bare Root vs. Potted Plants, Species Selection, and Caging Types for Restoration of a Prairie Wetland, and Quantitative Analysis and Descriptive Survey of Plant Communities and Associations at Lewisville Lake Environmental Learning Area (LLELA), Lewisville, TX
… in an early successional stage, dominated by the hackberry-elm-ash alliance, with small remnants of native Cross Timbers found in isolated patches. Species richness and diversity were highest in the forests and lowest in the wetlands; evenness, though not different across ecosystems, demonstrated …

Ecology of Fish Communities in Nebraska Sandhill Lakes
… exploitation. Creel survey data for Pelican and Hackberry lakes (Cherry County) suggested that bluegill exploitation was <10%. However, one unexploited yellow perch population in a privately owned water body exhibited high condition, fast growth, and was composed of a high proportion of large …

Winter Behavior and Ecology of Eastern Bluebirds (<i>Sialia sialis</i>): Home Ranges, Habitat Use, and Effect of Weather on Foraging Behavior
… low wind speeds, and the presence of snow. Hackberry (<em>Celtis occidentalis</em>), mistletoe (<em>Phoradendron leucarpum</em>), and red cedar (<em>Juniperus virginiana</em>) were the most commonly consumed fruits, but high winds may restrict their potential as a food resource. High winds, …

Spring Phenology and Trophic Ecology of Trees, Caterpillars, and Migrating Neotropical -Nearctic Songbirds
… of an ephemerally abundant insect prey, the hackberry psyllid, Pachypsylla celtidismamma. Later migrants foraged on caterpillars. In general, yellow-rumped warbler tree species use was associated with tree phenology and caterpillar abundance. This community-level research documented the …

Foraging ecology and sampling of Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) and its host Halyomorpha halys (Stal) (Hemiptera: Pentatomidae) in wild host trees
… (Mill.) Swingle), male tree of heaven, or hackberry (Celtis occidentalis L.), captured significantly more H. halys adults and nymphs near the top of the canopy than at mid- or lower canopy, regardless of host plant. The majority of H. halys egg masses collected via destructive sampling of …

Changes in Leaf Area and Nutrient Content of Celtis spp. Across a Precipitation Gradient in Texas
Nitrogen is a key nutrient for cell and protein function in both plants and animals, and the ratio of carbon to nitrogen in leaves is a good indicator of nutrient quality within an ecosystem. Studies have shown that an increase in precipitation increases leaf size and the C/N ratio, but can …
