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 mangroves …

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.


Assisted Migration Is Plausible For A Boreal Tree Species Under Climate Change: A Quantitative And Population Genetics Study Of Trembling Aspen (Populus Tremuloides Michx.) In Western Canada, Chen Ding, Jean S. Brouard 2022 Texas A&M Forest Service

Assisted Migration Is Plausible For A Boreal Tree Species Under Climate Change: A Quantitative And Population Genetics Study Of Trembling Aspen (Populus Tremuloides Michx.) In Western Canada, Chen Ding, Jean S. Brouard

Aspen Bibliography

A novel method was tested for improving tree breeding strategies that integrate quantitative and population genetics based on range-wide reciprocal transplant experiments. Five reciprocal common garden tests of Populus tremuloides were investigated including 6450 trees across western Canada focusing on adaptation traits and growth. Both genetic parameters and home-site transplant models were evaluated. We found a genetic trade-off between growth and early spring leaf flush and late fall senescence. Coefficients of phenotypic variation (CVp) of cell lysis (CL), a measure of freezing injury, shrank from 0.28 to 0.10 during acclimation in the fall, and the CVp slope versus …


Wetlands In Our Backyard: A Review Of Wetland Types In Virginia State Parks, Kirsten Bauer, Benjamin K. Campbell 2022 Longwood University

Wetlands In Our Backyard: A Review Of Wetland Types In Virginia State Parks, Kirsten Bauer, Benjamin K. Campbell

Virginia Journal of Science

Wetlands constitute a significant component of Virginia’s natural resources and heritage. Though historically they have been discounted—and often denigrated—the exceptional value of wetlands is currently growing in recognition and appreciation. In addition to the value provided by extracted resources and ecological regulation, wetlands also offer people the opportunity to enrich themselves through cultural, educational, and recreational pursuits. The state parks of Virginia provide access to a variety of ecosystems, including a wide array of wetland types. In this review, we document the diversity of wetlands in Virginia State Parks through a typology that groups wetland systems into the three principal …

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 stenoptera (Chopard, …

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 and …
