Effects Of Proximity To Roads On Tissue Surface Ph, Conductivity And Heavy Metal Contents Of A Grazing Grass Species, C. Munyati, M. S. Mathole

IGC Proceedings (1997-2023)

Globally, road networks are expanding in the countryside. Though beneficial to society, the roads potentially have detrimental effects on grazing quality. The effects are seldom quantified. In this study Eragrostis lehmanniana, a common native grazing grass in parts of the world, was examined for indicative data on the impacts of roads on grasses. Aboveground tissue samples were collected monthly on three occasions during the growing season, at the same respective locations near three high traffic highways. Non-senescent specimens were sampled along transects of up to 400 m perpendicular to the highways, starting from the road edge and then at …

A Comparative Analysis Of Rainwater Ph Levels In Regions Iii, Ncr, And Iv-A Through A Citizen Science Approach, Nicolo Maria Andre O. Da Silva, Dannon Andre M. Lewis, Krista Isabel I. Tenorio, Jaerey Austin E. Quitangon

With acid rain among its direct consequences, air pollution has been documented to threaten manmade infrastructures, human health, and natural ecosystems. The COVID-19 pandemic restricted today’s source of air pollutants, as it compelled various countries worldwide to limit socio-economic activities and transportation to mitigate the transmission of SARS-CoV-2. However, local research on air pollution has tended to concentrate on the Philippines’ capital Metro Manila alone and the earlier stages of the COVID-19 pandemic in terms of location and time. Through citizen science, this study determined the pH levels of rainwater during the COVID-19 pandemic in areas within Central Luzon, Metro …

The Effect Of Soil Ph On The Integument Of Western Tiger Salamanders, Aaron Devine, Dennis M. Ferraro

UCARE Research Products

This study was done in an effort to better understand the multifaceted issues in amphibian decline, specifically within the eastern regions of Nebraska, to determine whether or not human-induced acid rain contributed to the decline. This is a heavily important topic of research as amphibians worldwide are declining related to many issues that stem from climate change and several other environmental issues of that nature. This study looked to use acidic pH within soil from western Nebraska to determine the reactionary impacts (primarily lesions) the western tiger salamander had after being subjected to it. It was found that pH did …

Tb180: Baseline Data For Long-Term Forest Vegetation Monitoring At Bear Brook Watershed In Maine, J. D. Eckhoff, G. B. Wiersma

Technical Bulletins

This report includes comprehensive information on the primary and meta forest vegetation data assembled from Bear Brook Watershed in Maine (BBWM). This information represents the first in-depth inventory of the forest vegetation, both woody and non-woody in multiple strata, within the two watersheds initially established at BBWM, West Bear and East Bear, and also the areas adjacent to the east and west of these watersheds. For long-term monitoring of vegetation responses to the continued manipulations and/or the recovery of the ecosystems at BBWM, access to the vegetation baseline information contained within this report is essential.

Epistomatal Wax Injury To Red Spruce Needles (Picea Rubens Sarg.) Grown In Elevated Levels Of Ozone And Acidified Rain, C. R. Krause, W. N. Cannon Jr.

Scanning Microscopy

Red spruce seedlings (Picea rubens Sarg.) were exposed to charcoal-filtered air, at 0.07 ppm or 0.15 ppm ozone (O₃), alone or in combination with pH 4.2 or pH 3.0 acidified rain, and examined with scanning electron microscopy (SEM) to determine if epistomatal wax fine structure was affected. Acidified rain in combination with 0.15 ppm O₃ produced changes in wax tubule morphology. Changes were moderate at pH 4.2 and severe at pH 3.0. Needles collected from Whiteface Mountain, New York, displayed injured epistomatal wax structure similar to that observed on needles exposed in the laboratory to 0.15 …
