Population Ecology Of Spruce-Fir Forests Of The Interior West, Katheryn Little 2022 Utah State University

Population Ecology Of Spruce-Fir Forests Of The Interior West, Katheryn Little

All Graduate Theses and Dissertations

Spruce-fir forest type covers nearly 10 million acres of forested land in the interior west, but there is a lack of research defining how these forests grow for future planning. Stand density index (SDI) represents the average tree size and number of trees in a stand multiplied. Each species has specific maximum number the growing space can handle known as ‘fully stocked’. If the stand is fully stocked, it must wait until trees die for individuals to grow. Spruce and fir have similar maximum stocking values, and similar growth characteristics, allowing them to be plotted together. Using current forest data ...


Soil Carbon Within The Mangrove Landscape In Rufiji River Delta, Tanzania, Zhaohua Dai, Carl C. Trettin, Mwita M. Mangora, Wenwu Tang 2022 Michigan Technological University

Soil Carbon Within The Mangrove Landscape In Rufiji River Delta, Tanzania, Zhaohua Dai, Carl C. Trettin, Mwita M. Mangora, Wenwu Tang

Michigan Tech Publications

Mangroves are among the most carbon-rich terrestrial ecosystems, primarily attributable to the soil pool. There are substantial differences in soil carbon (C) and nitrogen (N) due to the disparities in geomorphic settings and ecological drivers, but this insight is drawn primarily from observational studies. An objective inventory of carbon stocks in mangroves of the Rufiji River Delta, Tanzania was conducted. Seventy-five soil cores were collected within a 12,164 ha inventory area, comprising the northern portion of the delta. Cores were collected from intact and dwarf mangroves, agricultural fields, and mudflats. The spatial mean soil organic carbon (SOC) density in ...

Research on mountain biking is growing across many academic disciplines, from medicine to outdoor recreation and tourism research. This bibliography includes peer-reviewed research published on mountain biking within the context of natural resource management from 1990-2021.


The Specific Richness Of Forest Cockroach Communities In The Region Of Aflou (Laghouat; Algeria), Fatiha Masna, Siham Bounadji, Saliha Benhissen, Zakaria Hedjouli, Abdelmadjid Yagoub Asloum, Sarra Habbachi, Waffa Habbachi 2022 Department of Natural Sciences, ENS Taleb Ebderrahman, Laghouat, Algeria

Journal of Bioresource Management

Forest cockroaches are among the insects that play an important and effective role in forest formations, they are insects with incomplete metamorphosis belonging to the order of Blattodea. This work is a contribution to the knowledge of Blattoptera species existing in the forest environments of Aflou’s region (Laghouat; Algeria).The inventory was carried out monthly in the El-Khnegue Forest (Aflou) from February 2019 to May 2019. It revealed the presence of six species of forest Cockroaches, which belongs to 4 genera of the Blattelidae family. After identification, it was demonstrated that, these species were: Dziriblatta nigriventris (Chopard, 1936), Dziriblatta ...


Image Processing In Dense Forest Areas Using Unmanned Aerial System (Uas), Parth Bhatt, Curtis Edson, Ann Maclean 2022 Michigan Technological University

Image Processing In Dense Forest Areas Using Unmanned Aerial System (Uas), Parth Bhatt, Curtis Edson, Ann Maclean

Michigan Tech Publications

Description:

A detailed workflow using Structure from Motion (SfM) techniques for processing high-resolution Unmanned Aerial System (UAS) NIR and RGB imagery in a dense forest environment where obtaining control points is difficult due to limited access and safety issues.

Abstract:

Imagery collected via Unmanned Aerial System (UAS) platforms has become popular in recent years due to improvements in a Digital Single-Lens Reflex (DSLR) camera (centimeter and sub-centimeter), lower operation costs as compared to human piloted aircraft, and the ability to collect data over areas with limited ground access. Many different application (e.g., forestry, agriculture, geology, archaeology) are already using ...

European Mushroom Assemblages Are Phylogenetically Structured By Temperature, Claus Bässler, Jacob Heilmann-Clausen, Carrie Andrew, Lynne Boddy, Ulf Büntgen, Jeffrey Diez, et. al. 2022 Goethe-Universität Frankfurt am Main

European Mushroom Assemblages Are Phylogenetically Structured By Temperature, Claus Bässler, Jacob Heilmann-Clausen, Carrie Andrew, Lynne Boddy, Ulf Büntgen, Jeffrey Diez, Et. Al.

Michigan Tech Publications

Recent global warming affects species compositions at an unprecedented rate. To predict climate-induced changes in species assemblages, a better understanding of the link between species occurrence and climate is needed. Macrofungal fruit body assemblages are correlated with the thermal environment at the European scale. However, it is still unknown whether macrofungal communities are also phylogenetically structured by thermal environments. Thermal environments are characterized by annual temperature means but also by intra-annual temperature variability (hereafter termed temperature seasonality), which are both considered in this study. Here, we used distribution data of 2882 species based on fruit body records across Europe to ...


Post-Fire Erosion Following The Czu Lightning Complex Fire: Quantifying Hillslope Erosion And Providing Guidance Towards Improving Post-Fire Response, Matthew C. Crockett, Matthew Crockett 2022 California Polytechnic State University, San Luis Obispo

Post-Fire Erosion Following The Czu Lightning Complex Fire: Quantifying Hillslope Erosion And Providing Guidance Towards Improving Post-Fire Response, Matthew C. Crockett, Matthew Crockett

Master of Science in Environmental Sciences and Management Projects

The size and severity of wildfires have increased in California during recent decades. This trend is highlighted through the CZU Lightning Complex fire of August 2020 which burned over 86,000 acres in the Santa Cruz mountains of California. The fire greatly impacted the Little Creek watershed, a roughly 1,300 acre watershed that exists largely within Cal Poly San Luis Obispo’s Swanton Pacific Ranch (SPR). The current trends of California’s increased wildfire regime are expected to continue, raising concerns regarding the direct and secondary effects on forest watersheds and the effectiveness of current post-fire erosion control management ...


Nutrient Dynamics And Ecosystem Development Of Urban Forests, Gisselle A. Mejía 2022 The Graduate Center, City University of New York

Nutrient Dynamics And Ecosystem Development Of Urban Forests, Gisselle A. Mejía

Dissertations, Theses, and Capstone Projects

Urban growth and expansion are a major component of global environmental change, with impacts on climate, air and water quality, biodiversity, and human well-being. Forests embedded in urban landscapes are critical in mitigating these impacts at local, regional, and continental scales. However, assessing urban forests is difficult because cities are heterogenous in physical, chemical, biological, and social dimensions. This heterogeneity has constrained how urban forests are defined, and therefore, how they are studied. The objective of this dissertation is to determine how these biophysical and social factors drive ecological processes in urban forests and will address three outstanding challenges in ...
