Maple River Dam Removal Stream Ecology Data
Over the past two decades, dam removal has become an increasingly important aspect of aquatic ecology. The motivation for the removal broadly ranges from purely ecological terms, restoring stream or river connectivity, through safety concerns, as a result of crumbling infrastructure, to economic concerns, increasing local tourism, recreational fishing, or canoeing and kayaking. As a result of this work, ecological studies have arisen that monitor the changes to the riverine ecosystem as a result of removal. Unfortunately, given the uncertain nature of funding and public concerns over dam removal, long term longitudinal studies that cover multiple trophic levels are difficult to find. Fortunately, the University of Michigan Biological Station has been involved in the ecological monitoring of a headwater river (the Maple River) in the northern part of the lower peninsula of Michigan. Through the tremendous intellectual resources available at the station, the physical, chemical, and some biological aspects of this river’s ecology has been measured for eight years prior to the dam removal, during the dam removal, and for two years post-dam removal. The results presented here show that the ecology of the river recovered within this two-year period, but had a different ecological state driven. This new state is primarily driven increases in flow, ammonia, silica, and increases in the populations of the macroinvertebrate feeding guilds of filterers and scrapers. In addition, decreases in stream pH and water temperature contributed to this new state. The results and observations presented here may provide some guidance for other long term monitoring studies.

White oak and red maple foliar chemistry of urban and reference forests of the eastern US
Foliar chemistry values were obtained from two important native tree species (white oak (Quercus alba L.) and red maple (Acer rubrum L.)) across urban and reference forest sites of three major cities in the eastern United States during summer 2015 (New York, NY (NYC); Philadelphia, PA; and Baltimore, MD). Trees were selected from secondary growth oak-hickory forests found in New York, NY; Philadelphia, PA; and Baltimore, MD, as well as at reference forest sites outside each metropolitan area. In all three metropolitan areas, urban forest patches and references forest sites were selected based on the presence of red maple and white oak canopy dominant trees in patches of at least 1.5 hectares with slopes less than 25%, and well-drained soils of similar soil series within each metropolitan area. Within each city, several forest patches were selected to capture the variation in forest patch site conditions across an individual city. All reference sites were located in protected areas outside of the city and within intermix wildland-urban interface landscapes, in order to target similar contexts of surrounding land use and population density (Martinuzzi et al. 2015). Several reference sites were selected for each city, located within the same protected area considered representative of rural forests of the region. White oaks were at least 38.1 cm diameter at breast height (DBH), red maples were at least 25.4 cm DBH, and all trees were dominant or co-dominant canopy trees. The trees had no major trunk cavities and had crown vigor scores of 1 or 2 (less than 25% overall canopy damage; Pontius & Hallett 2014). From early July to early August 2015, sun leaves were collected from the periphery of the crown of each tree with either a shotgun or slingshot for subsequent analysis to determine differences in foliar chemistry across cities and urban vs. reference forest site types. The data were used to invstigate whether differences in native tree physiology occur between urban
Differential impacts of calcium and aluminum treatments on foliar and sapwood nutrition and metabolism of sugar maple trees growing at the west edge of WS6 of the Hubbard Brook Experimental Forest from 1997-2009.
Plot levels Ca and Al additions study at WS6 BACKGROUD: To better evaluate the interaction of Ca depletion and Al mobilization on a northern hardwood forest, the Nutrient Perturbation (NuPert) study was initiated in 1995, west of the biogeochemical reference watershed (W6) at the HBEF (43.95411°N, 71.74779°W). The study area is on a south-facing slope, with an elevational range of 700–760 m, and most soils are classified as either Aquic Haplorthods or Aquic Haplumbredts (Halman et al. 22015 and references therein). Twelve sugar maple (Acer saccharum Marshall) dominated plots (45 m × 45 m) were randomly assigned to one of three treatments (Ca addition, Al addition, or control (no addition)), yielding four replicates of each treatment in the study. In addition to sugar maple, American beech (Fagus grandifolia Ehrh.) and yellow birch (Betula alleghaniensis Britt.) are co-occurring tree species in these plots, whereas hobblebush (Viburnum lantanoides Michx.) and striped maple (Acer pensylvanicum L.) dominate the understory. Treatments began in 1995 with annual CaCl2 (2.5 g·m−2) and AlCl3 (0.9 g·m−2) applications occurring each fall or spring during leafless periods. The use of CaCl2 was halted in 1999 in favor of a one-time application (38 g·m−2) of wollastonite (CaSiO3, a slow-release form of Ca). Thereafter, AlCl3 additions occurred in alternate years in fall or spring. Foliage was collected from sunlit branches in the upper to mid canopy dominant sugar maple trees. Five trees per plot of each group were selected for sampling in August 2008. There was an ice storm in 1998 at this site which might have interfered with this study findings. In 2009, tiny sapwood plugs were also collected. All the analyses were carried out using the procedures described under section A (Ca-supplementation study). SUMMARY: Acid deposition induced losses of calcium (Ca) from northeastern forests have had negative effects on forest health for decades, including the mobilization of potentiall
Climate Change Across Seasons Experiment (CCASE) at the Hubbard Brook Experimental Forest; concentrations of foliar metabolites: polyamines, amino acids, chlorophyll, carotenoids, soluble proteins, soluble elements, sugars, and total nitrogen and carbon in red maple (Acer rubrum) trees.
Foliage was collected in 2015 and 2017 from red maple trees at the Climate Change Across Seasons Experiment (CCASE) as part of the Hubbard Brook Ecosystem Study (HBES). Analyses of foliar metabolites include polyamines, amino acids, chlorophylls, carotenoids, soluble proteins, soluble inorganic elements, sugars, and total nitrogen and carbon. There are six (11 x 14m) plots in total in this study; two control (plots 1 and 2), two warmed 5 degrees (°) Celsius (C) above ambient throughout the growing season (plots 3 and 4), and two warmed 5 °C in the growing season, with snow removal during the winter to induce soil freezing and then warmed with buried heating cables to create a subsequent thaw (plots 5 and 6). Each soil freeze/thaw cycle includes 72 hours of soil freezing followed by 72 hours of thaw. Four kilometers (km) of heating cable are buried in the soil to warm these four plots. Together, these treatments led to warmer growing season soil temperatures and an increased frequency of soil freeze-thaw cycles (FTCs) in winter. Our goal was to determine how these changes in soil temperature affect foliar nitrogen (N) and carbon metabolism of red maple trees. These data were gathered as a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
Vertical stratification of leaf physical traits exerts bottom-up pressures on insect herbivory in a sugar maple temperate forest
<p>Do vertical gradients in temperate forest structure insect herbivore communities? We tested the hypothesis that the increase in light intensity from understory to forest canopy level drives differences in leaf physical traits and budburst phenology that impact insect herbivores and thus play a role in structuring both herbivore communities and the leaf damages they cause. Twelve sugar maple <em>(Acer saccharum)</em> sites were monitored in southern Quebec, examining insect herbivore patterns from understory to the shaded and sun canopy over the summers of 2020, 2021, and 2022. Additionally, we recorded leaf physical traits, temperature, humidity, and sun exposure. Our findings revealed that leaf thickness increased along the vertical gradient in 2021, making leaves less favorable to herbivores in the canopy level. Accordingly, we recorded a consistent decrease in insect herbivory damage rates from the understory to the shaded canopy and sun canopy in 2020 and 2021, driven by leaf cutters, skeletonizers, stipplers, and leaf miners. These results support our hypothesis that variation in plant physical traits due to sun exposure contributes to the vertical stratification of insect damage. In 2022, the gradient of insect herbivore abundance corroborated the observed damage trends from the previous years. Moreover, we calculated an average annual herbivory rate of 9.1% of the leaf surface in our study site, suggesting limited evidence supporting a significant contribution of background herbivory to the decline of sugar maple forests. Overall, our study highlights the importance of vertical gradients in structuring insect herbivore communities and emphasizes the role of leaf traits in mediating these interactions.</p>
