European House Borer Regulations, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Pinewood movement restrictions

To minimise the spread of EHB in Western Australia (WA), restrictions on the movement of pinewood were implemented in 2006, and currently apply to areas where EHB occurs. By restricting the movement of pinewood from EHB infested areas, EHB has been contained to Restricted Movement Zones (RMZs) in the greater Perth metropolitan area.

The restrictions are described in the Agriculture and Related Resources Protection (European House Borer) Regulations 2006.

The regulations allowed for the establishment of quarantine zones, Priority Management Zones (PMZs) and RMZs, and placed restrictions not only on untreated pinewood movement from PMZs and RMZs …

How Elevation Affects Epiphyte Distribution: An Analysis In Epiphyte Distribution Changes At Different Elevations And Tree Strata In Santa Lucia Cloud Forest Reserve, Ecuador, Nicole L. Melnick

Independent Study Project (ISP) Collection

Cloud forests are unique ecosystems due to their tropical nature, high elevations, and extremely high presence of epiphytes that serve many important roles for the ecosystem’s biotic and abiotic components. As epiphytes can make up anywhere from one-quarter (Foster 2001) to a half (Gómez González et al. 2017) of all local plant species in cloud forests, it is essential to understand how their habitat distributions change with elevation and whether climate change will have a significant effect on that. This study used observational survey methods to record the amount of monocots (separately counted bromeliads and orchids), dicots, ferns, and percent …

Afforestation And Biodiversity: Bryophyte Richness Changes Between Icelandic Forest Types, Kian Mcdonough

Independent Study Project (ISP) Collection

Forest-dwelling bryophytes (mosses, liverworts, hornworts) greatly contribute to biodiversity and ecosystem function but are largely under-studied in comparison to vascular plants. With Iceland’s large-scale afforestation efforts there is a need to understand how different afforestation species are affecting biodiversity, including bryophyte diversity. This study looked at differences in ground-floor bryophyte richness across Sitka spruce, lodgepole pine, and downy birch forests and found that bryophyte richness was highest in the Sitka spruce forests and lowest in downy birch forests. While this suggests a negative correlation between bryophyte richness and light availability, since the conifer species have the densest copy cover, other …

Laguncularia Racemosa Top-Layer Sediment Microorganism Makeup In Relation To Differing Levels Of Perceived Anthropogenic Impact In Bocas Del Drago, Bocas Del Toro, Panama, Gabrielle Glendening

Independent Study Project (ISP) Collection

As mangrove forests are destroyed by human factors across the earth, many crucial ecological processes that take place in these systems of trees are obstructed. One of the most important roles played by mangroves is their ability to sequester carbon in the sediment, as this storage of carbon helps diminish atmospheric warming. Many sediment microorganisms help in this process of carbon sequestration and play various other vital roles in mangrove ecosystems. Microorganisms in marine sediments can be used to assess the health of the surrounding environment. Past research has found significant differences in sediment microorganism composition, abundance, and diversity in …

Creating Sustainable Biofuels Using Essential Oil Distillery Leaf Waste Near Vohimana Reserve, Ashley Cohen

Independent Study Project (ISP) Collection

Like most of Madagasacar’s population, people around Vohimana Reserve rely on traditional fuels like firewood and charcoal for cooking and heating. As a result, the region is facing deforestation, which poses a threat to biodiversity and the livelihoods of local populations. A local essential oil distillery was created by the NGO L’Homme et L’Environnement as a sustainable income generator to combat deforestation and protect biodiversity. The distillery produces leaf biomass that can be mixed with binding agent(s) and transformed into biofuel as a sustainable alternative to traditional fuels. 14 biofuels were created by combining distillery leaf biomass and various percent …

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 …

Observational Study Of Woolly Monkey Behavior And Vocalizations: Behavioral Time Allotment And Vocalization Habits Of A Small Population Of Poeppig’S Woolly Monkey (Lagothrix Lagotricha Poeppigii) In The Ecuadorian Amazon, Marina Smith-Hanke

Independent Study Project (ISP) Collection

Poeppig’s woolly monkey (Lagothrix lagotricha poeppigii), a species of primate native to the Amazonian regions of western Brazil, eastern Ecuador, and northeastern Peru, is classified as endangered by the IUCN. These large, frugivorous primates are threatened by habitat loss and climate change as a result of human interference. Deforestation, hunting, petroleum mining, and illegal trafficking are all huge threats to this species. As a result of these pressures, their populations have decreased by at least 30% over the past three generations. However, as keystone seed dispersers, they are essential for Amazonian ecosystem health; without their seed dispersal services, a loss …

What’S At “Steak”: The Drivers Of Deforestation In The Brazilian Amazon And Potential Multilateral Solutions, Soleil Gaylord

Independent Study Project (ISP) Collection

This paper examines the contemporary drivers of deforestation in the Brazilian Legal Amazon and how multilateral solutions can be employed to bring forest loss to zero. Insights from the scholarly literature and five expert interviews allow a critical assessment of how the rise of unilateralism presents a novel threat to the Brazilian Legal Amazon and, by proxy, those relying on the region’s raw resources and ecosystem services. Integrating analyses of both Brazilian institutional structures and global environmental governance frameworks, this study examines the primary historical and contemporary factors driving accelerated deforestation rates observed under Brazil’s President Jair Bolsonaro. In identifying …

The Role Of Frugivorous Birds As Seed Dispersers: Feeding Selection And Preference Of Madagascar’S Avian Frugivores In Analamazaotra Forest, Thaddeus Bashaw

Independent Study Project (ISP) Collection

Madagascar is a country rich in floral and faunal diversity. However, anthropogenic habitat destruction and climate change increasingly threaten its biodiversity. Endozoochorous plants that dependent on frugivory for seed dispersal are under threat due to increasing rates of localized extinctions of frugivorous lemurs, the primary seed dispersers of the island. While lemurs are the islands most abundant frugivores, other frugivorous vertebrates like birds and bats likely play a significant role in seed dispersal, although this role is still poorly understood. This study, conducted in Analamazaotra forest, compares the rates of visitation and consumption of six endemic fruiting tree species by …

Whole-Tree Harvest Effects On Macronutrients In An Oak-Dominated System After Seven Years, Robert Richard, Evan Kane, Dustin Bronson, Randall Kolka

Michigan Tech Publications, Part 1

This study assesses the impacts of whole-tree harvesting (WTH) versus stem-only harvest (SOH) on two oak-dominated stands located in Northern Wisconsin. Specifically, our study follows up on an experiment designed to better understand the impacts of WTH and whether stands are at risk of long-term nutrient losses, which could contribute to declines in productivity. The original study assessed: (i) full biomass removal (referred to as WTH), (ii) partial biomass removal (removal to 5 cm diameter bole), (iii) a traditional SOH (removal to 10 cm bole), and (iv) no harvest (control). Our data were collected 93 months after harvest and showed …

Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers

Aspen Bibliography

Upland aspen (Populus spp.) forests contribute significantly to biodiversity in their circumboreal role as keystone species. As aspen ecosystems flourish or diminish, myriad dependent species follow suit. The 43-hectare Pando aspen (Populus tremuloides Michx.) clone in Utah, USA, is thought to be the largest living organism on earth, but is faltering due to chronic herbivory. Long-term resilience in aspen communities, including Pando, rests on successful recruitment of vegetative suckers that are nutritiously desirable to browsing ungulates. Here, I evaluate aspen reproduction alongside numerous vital indicators of Pando's status in the first trend assessment of this embattled iconic forest. …

Recovery Of Soil Microbial Diversity And Functions Along A Tropical Montane Forest Disturbance Gradient, Renee Sniegocki, Jessica B. Moon, Abigail L. Rutrough, Jude Gireneus, Jaya Seelan Sathiya Seelan, Michael C. Farmer, David C. Weindorf, Kusum Naithani

Biological Sciences Faculty Publications and Presentations

Logging and forest conversion are occurring at alarming rates in tropical forests. These disturbances alter soil microbial community structure and functions. While direct links between changes in soil properties, such as pH and microbial community structure are well established, the indirect effects of logging and forest conversion on soil microbial community structure and functions are poorly understood. We used a space-for-time substitution to investigate the changes in soil microbial diversity and functions across a forest recovery gradient in the tropical montane forests of northern Borneo. We used surface (top 5 cm) soil to assess soil physicochemical and microbial (next-generation DNA …
